Pete Zalewski.Pete Zalewski. [Source: NBC]Because the talkback button on Flight 11 has been activated, Boston Center air traffic controllers can hear a hijacker on board say to the passengers: “We have some planes. Just stay quiet and you’ll be OK. We are returning to the airport.” (Johnson 11/23/2001; 9/11 Commission 7/24/2004, pp. 19) Air traffic controller Pete Zalewski recognizes this as a foreign, Middle Eastern-sounding voice, but does not make out the specific words “we have some planes.” He responds, “Who’s trying to call me?” Seconds later, in the next transmission, the hijacker continues: “Nobody move. Everything will be OK. If you try to make any moves you’ll endanger yourself and the airplane. Just stay quiet.” (Wald and Sack 10/16/2001; 9/11 Commission 6/17/2004; MSNBC 9/9/2006) Bill Peacock, the FAA director of air traffic services, later claims, “We didn’t know where the transmission came from, what was said and who said it.” David Canoles, the FAA’s manager of air traffic evaluations and investigations, adds: “The broadcast wasn’t attributed to a flight. Nobody gave a flight number.” (Murray 9/11/2002) Similarly, an early FAA report will state that both these transmissions came from “an unknown origin.” (Federal Aviation Administration 9/17/2001 pdf file) Zalewski asks for an assistant to help listen to the transmissions coming from the plane, and puts its frequency on speakers so others at Boston Center can hear. Because Zalewski didn’t understand the initial hijacker communication from Flight 11, the manager of Boston Center instructs the center’s quality assurance specialist to “pull the tape” of the transmission, listen to it carefully, and then report back. They do this, and by about 9:03 a.m. a Boston manager will report having deciphered what was said in the first hijacker transmission (see 9:03 a.m. September 11, 2001). (9/11 Commission 6/17/2004; MSNBC 9/9/2006) Fellow Boston controller Don Jeffroy also hears the tape of the hijacker transmissions, though he doesn’t state at what time. He says: “I heard exactly what Pete [Zalewski] heard. And we had to actually listen to it a couple of times just to make sure that we were hearing what we heard.” (MSNBC 9/11/2002) At some point, Ben Sliney, the national operations manager at the FAA’s Herndon Command Center, gets word of the “We have some planes” message, and later says the phrase haunts him all morning. American Airlines Executive Vice President for Operations Gerard Arpey is also informed of the “strange transmissions from Flight 11” at some point prior to when it crashes at 8:46 a.m. (Levin, Adams, and Morrison 8/12/2002) Boston Center will receive a third transmission from Flight 11 about ten minutes later (see (8:34 a.m.) September 11, 2001).

A Sikorsky S-76A helicopter flying over New York.
A Sikorsky S-76A helicopter flying over New York. [Source: Sikorsky]A helicopter is tracked on radar apparently crashing into the World Trade Center, according to a report later given by a New York air traffic controller over an FAA teleconference.
Helicopter Is 'the Only Target that We Saw ... to Fly into the Trade Center' - At around 10:15 a.m., Tom White, an operations manager at the FAA’s New York Terminal Radar Approach Control (TRACON), will tell those on the FAA teleconference that his facility tracked a Sikorsky helicopter that had taken off from the airport in Poughkeepsie, New York, and this helicopter appeared to fly into the WTC at 8:27 a.m. (see (10:15 a.m.) September 11, 2001). White will add that, after replaying radar information, it is concluded that the helicopter is “the only target that we saw in the vicinity of the Trade Center at 12:27 [Zulu time, or 8:27 a.m. Eastern time] to fly into the Trade Center.” (Federal Aviation Administration 9/11/2001; 9/11 Commission 5/21/2004) (However, the first crash at the WTC will not occur until 8:46 a.m. (see 8:46 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 7) ) The “Poughkeepsie airport” the helicopter took off from is presumably Dutchess County Airport. Sikorsky reportedly bases a fleet of its S-76 helicopters at Dutchess County Airport, “dispatching them to the New York metro areas as needed.” (Venable 5/2000; Wagstaff 8/1/2003) Poughkeepsie is about 70 miles north of New York City. (Sherman 2/3/2008)
Helicopter 'Consistent with the Speed' of What Hits WTC - White will say the helicopter’s tail number is N7601S, that it departed the Poughkeepsie airport at 8:03 a.m., and that it then headed south at a speed of around 160 knots, or 184 miles per hour. He will add: “The tower [presumably the air traffic control tower at the Poughkeepsie airport] says the only thing they had southbound at that time was a Sikorsky helicopter, which is consistent with the speed that we followed it down.… They’re saying they replayed the radar and it’s consistent with the speed of what went into the [WTC] tower.” (Federal Aviation Administration 9/11/2001) (However, an analysis by the US government will later estimate that Flight 11 hits the WTC at 494 miles per hour, or 429 knots, which is significantly faster than the helicopter was flying. (Lipton and Glanz 2/23/2002) )
Mistaken Information Later Corrected - It will apparently take until early afternoon for the suspicions about the Sikorsky helicopter hitting the WTC to be dismissed. An FAA chronology of this day’s events will state that at 1:00 p.m., the “Sikorsky helicopter” is “now believed not to have hit the WTC.” (Federal Aviation Administration 1/2/2002) Another FAA chronology will state that at 1:04 p.m., it is reported that the Sikorsky helicopter “landed 20 minutes early, normal GE run at 12:28Z [i.e. 8:28 a.m. Eastern time] to WTC.” (It is unclear what is meant by “normal GE run.”) (Federal Aviation Administration 9/11/2001)

Steve Bongardt.Steve Bongardt. [Source: Government Matters]Steve Bongardt, an agent at an FBI office in Manhattan, reads a report on his computer about Osama bin Laden reopening his underground facility in Afghanistan and he will subsequently determine that this incident is related to the attacks on the World Trade Center. (Wright 2006, pp. 356-357; Graff 2011, pp. 309-310) Bongardt is a member of the FBI’s I-49 squad. (Wright 2006, pp. 377) The squad is focused on bin Laden and al-Qaeda’s central command. It is based in an office on the eighth floor at 290 Broadway, across the street from the FBI’s New York field office at 26 Federal Plaza. (Graff 2011, pp. 205-206) Bongardt is one of the first people to arrive at the office this morning, coming into work sometime before 8:30 a.m. He turns on his computer and reads some of the day’s intelligence. He is puzzled by one particular piece of information he sees. “A report had Osama bin Laden reopening his large underground facility at Tora Bora in Afghanistan and sprucing it up,” journalist and author Garrett Graff will write. According to author Lawrence Wright, the report states that “the al-Qaeda camps in Tora Bora [are] being revitalized.” (Wright 2006, pp. 356-357; Graff 2011, pp. 309) The Tora Bora encampment is a “natural and manmade fortress of caves and bunkers,” according to the Chicago Tribune. It comprises a “series of rooms and tunnels,” and can “comfortably house 1,000 people,” according to an Afghan who visited the complex a few months ago. (Diamond and Lev 11/28/2001) “That can’t be good,” Bongardt thinks upon reading the report. “What the hell is [bin Laden] doing?” he wonders. Bongardt will feel the room shake when Flight 11 crashes into the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), and promptly head out of the building. He will realize what has happened when he sees that both of the Twin Towers are on fire and notices a massive jetliner engine lying on the street. He will then connect what is occurring to the report he read on his computer. He will understand that “this was the work of bin Laden,” according to Wright. “This is al-Qaeda. This is why they’re polishing up Tora Bora,” he will think. (Wright 2006, pp. 357-359; Graff 2011, pp. 309-310)

Captain Charles Leidig. 
Captain Charles Leidig. [Source: US Navy]Brigadier General Montague Winfield, the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, leaves his post to attend a pre-scheduled meeting, allowing a colleague, who only recently qualified to take over his position, to stand in for him, and not returning to his post until after the terrorist attacks have ended. (9/11 Commission 7/21/2003 pdf file; 9/11 Commission 4/29/2004 pdf file; 9/11 Commission 6/17/2004)
Winfield Attends Air Force-Convened Meeting - Winfield leaves his post to attend what a 9/11 Commission memorandum will call “an unrelated, closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers.” (9/11 Commission 7/21/2003 pdf file) Another Commission memorandum will state that this meeting is a “session for general officers who rated Air Force officers.” It is unclear whether the meeting takes place somewhere in the NMCC or outside the center. The Commission memorandum will only say that it takes place “elsewhere in [Joint Chiefs of Staff] spaces.” At least one of the NMCC’s other qualified DDOs, Brigadier General Norman Seip, is also attending it.
Winfield Asked Colleague to Replace Him on Previous Day - Winfield is temporarily replaced as DDO by Captain Charles Leidig. Leidig only joined the operations directorate of the Joint Chiefs of Staff in July 2001, when he assumed duties as the deputy for Command Center operations. In that, his usual role, he is responsible for the maintenance, operation, and training of watch teams for the NMCC. He qualified to stand in as the DDO in the NMCC about a month ago, in August 2001. The previous afternoon, Winfield asked Leidig to relieve him for a portion of his duty this morning, and Leidig agreed to do so.
Leidig Takes Over as DDO - As arranged, Leidig takes over from Winfield as DDO at 8:30 a.m., allowing Winfield to attend his meeting. Upon arrival at the NMCC, Leidig receives the intelligence and other turn over briefings. After seeing the reports of the plane crashes in New York on television, he will be responsible for convening a significant event conference (see 9:29 a.m.-9:34 a.m. September 11, 2001), which he soon upgrades to an air threat conference (see 9:37 a.m.-9:39 a.m. September 11, 2001). (9/11 Commission 4/29/2004 pdf file; 9/11 Commission 6/17/2004 pdf file)
Winfield Does Not Resume Duties until Attacks Are Over - Even though it becomes obvious that a coordinated attack is under way when television shows the second plane hitting the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Winfield apparently remains in his meeting instead of resuming his duties as DDO (see (Shortly After 9:03 a.m.) September 11, 2001). He will only take over from Leidig as DDO after Flight 93 crashes in Pennsylvania, apparently at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). (9/11 Commission 4/29/2004 pdf file; 9/11 Commission 6/17/2004) In later interviews for television, Winfield will give the impression that he remained in charge of the NMCC throughout the 9/11 attacks, and make no mention of having allowed a stand-in to take his place during this most critical period of time. (CNN 9/4/2002; ABC News 9/11/2002)

After being informed of the hijacking of Flight 11, Tim Spence, an operational supervisor at the FAA’s Cape Terminal Radar Approach Control (TRACON), calls the air traffic control tower and then the operations desk at Otis Air National Guard Base, to let them know that they might soon be receiving an order to scramble the base’s fighter jets. (9/11 Commission 9/30/2003 pdf file; 9/11 Commission 2004) Daniel Bueno, a supervisor at the FAA’s Boston Center, has just called Spence at the Cape TRACON, which is located on Otis Air Base at Cape Cod, Massachusetts, and said he wanted fighter jets scrambled in response to Flight 11, which is a “possible hijack.” Spence told Bueno he would contact Otis Air Base and see what it could do to help (see 8:34 a.m. September 11, 2001). (Federal Aviation Administration 4/19/2002; 9/11 Commission 9/30/2003 pdf file; 9/11 Commission 8/26/2004, pp. 12)
TRACON Supervisor Calls Otis Tower - Spence will later recall that in the five minutes following the call from Bueno, he makes “as many calls as possible.” He gets on the phone to the air traffic control tower at Otis Air Base, to notify the controllers there of the situation and receive information on who to call next, so as to facilitate Bueno’s request. Spence will recall that the Otis tower controller he speaks to gives him the telephone number for either Otis Air Base’s base operations or the supervisor of flying desk, which is the aviation section of the base operations desk. (He will be unable to recall exactly which number he is given.) Spence will say he “may have been given a second number” by the Otis tower controller, but he “does not recall directly.”
TRACON Supervisor Calls Operations Desk - Spence then calls Otis Air Base’s operations desk. He will later be unable to remember who he speaks with there. But, he will recall, the “general discussion” he has with them is “an introduction of his position, the relay of the information of a hijack from [the FAA’s Boston Center], and a request for information on how to get a fighter scramble.” During the call, Spence acknowledges that he has no authority to authorize a fighter scramble, but he advises those at the base to prepare to receive a scramble order (presumably from NEADS, NORAD’s Northeast Air Defense Sector), since such an order is “probably on its way.” The person at the operations desk gives Spence the phone number for NEADS.
Timing of Calls Unclear - The exact times when Spence calls the control tower and the operations desk at Otis Air Base are unclear. Spence will tell the 9/11 Commission that he makes the call to the control tower immediately after receiving the call from Bueno. (9/11 Commission 9/30/2003 pdf file) That call ended just before 8:36 a.m. (Federal Aviation Administration 4/19/2002) However, according to the 9/11 Commission Report, “the first notification received by the military—at any level—that American 11 had been hijacked” is when the FAA’s Boston Center calls NEADS just before 8:38 a.m. (see (8:37 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 20) If correct, that would indicate Spence calls the Otis tower at 8:38 a.m. or after. Bueno also called the Otis tower directly, to request military assistance in response to Flight 11 (see (Between 8:30 a.m. and 8:40 a.m.) September 11, 2001), and the tower controller subsequently contacts the base’s operations desk to alert it to the possible hijacking (see (Between 8:31 a.m. and 8:40 a.m.) September 11, 2001). (Filson 2003, pp. 47; Spencer 2008, pp. 22, 27-28) It is unclear whether the tower controller calls the operations desk before or after Spence calls it, although Spence will suggest to the 9/11 Commission that Otis Air Base “may have just received a call themselves regarding the situation” when he makes his calls, “but he is not sure.” (9/11 Commission 9/30/2003 pdf file)

Tech. Sgt. Jeremy Powell.Tech. Sgt. Jeremy Powell. [Source: Scott A. Gwilt/ Rome Sentinel]The FAA’s Boston Center calls NORAD’s Northeast Air Defense Sector (NEADS) in Rome, NY, to alert it to the suspected hijacking of Flight 11. According to the 9/11 Commission, this is “the first notification received by the military—at any level—that American 11 had been hijacked.” (9/11 Commission 7/24/2004, pp. 20; 9/11 Commission 8/26/2004, pp. 13) The call is made by Joseph Cooper, an air traffic controller at the Boston Center, and answered by Jeremy Powell, a technical sergeant on the NEADS operations floor. (Bronner 8/1/2006; Spencer 2008, pp. 25) Beginning the call, Cooper says: “Hi. Boston Center TMU [traffic management unit], we have a problem here. We have a hijacked aircraft headed towards New York, and we need you guys to, we need someone to scramble some F-16s or something up there, help us out.” Powell replies, “Is this real-world or exercise?” Cooper answers, “No, this is not an exercise, not a test.” (9/11 Commission 7/24/2004, pp. 20) Shortly into the call, Powell passes the phone on to Lieutenant Colonel Dawne Deskins (see (8:38 a.m.) September 11, 2001). Deskins identifies herself to Cooper, and he tells her, “We have a hijacked aircraft and I need you to get some sort of fighters out here to help us out.” (Seely 1/25/2002; ABC News 9/11/2002; Bamford 2004, pp. 8; Spencer 2008, pp. 26)
Military Claims Call Goes against Procedure - The 1st Air Force’s official history of the response to the 9/11 attacks will later suggest that Boston Center is not following normal procedures when it makes this call to NEADS. It states: “If normal procedures had taken place… Powell probably wouldn’t have taken that phone call. Normally, the FAA would have contacted officials at the Pentagon’s National Military Command Center who would have contacted the North American Aerospace Defense Command. The secretary of defense would have had to approve the use of military assets to assist in a hijacking, always considered a law enforcement issue.” The only explanation it gives for this departure from protocol is that “nothing was normal on Sept. 11, 2001, and many say the traditional chain of command went by the wayside to get the job done.” (Filson 2003, pp. 51)
Accounts Conflict over Time of Call - There will be some conflict between different accounts, as to when this vital call from Boston Center to NEADS occurs. An ABC News documentary will indicate it is made as early as 8:31 a.m. (ABC News 9/11/2002) Another ABC News report will state, “Shortly after 8:30 a.m., behind the scenes, word of a possible hijacking [reaches] various stations of NORAD.” (ABC News 9/14/2002) NEADS logs indicate the call occurs at 8:40 a.m., and NORAD will report this as the time of the call in a press release on September 18, 2001. (Federal Aviation Administration 9/17/2001 pdf file; North American Aerospace Defense Command 9/18/2001) The 8:40 time will be widely reported in the media prior to the 9/11 Commission’s 2004 report. (Associated Press 8/21/2002; BBC 9/1/2002; Adcock 9/10/2002; CNN 9/11/2002) But tape recordings of the NEADS operations floor that are referred to in the 9/11 Commission Report place the call at 8:37 and 52 seconds. (9/11 Commission 7/24/2004, pp. 20; Bronner 8/1/2006) If the 8:37 a.m. time is correct, this would mean that air traffic controllers have failed to successfully notify the military until approximately 12 minutes after they became certain that Flight 11 had been hijacked (see (8:25 a.m.) September 11, 2001), 16 minutes after Flight 11’s transponder signal was lost (see (Between 8:13 a.m. and 8:21 a.m.) September 11, 2001), and 24 minutes after the plane’s pilots made their last radio contact (see 8:13 a.m. September 11, 2001). (9/11 Commission 6/17/2004) At 8:34, the Boston Center tried contacting the military through the FAA’s Cape Cod facility, which is located on Otis Air National Guard Base, but was told that it needed to call NEADS (see 8:34 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 20; Spencer 2008, pp. 22)

Colin Scoggins, the military liaison at the FAA’s Boston Center, calls the FAA’s New York Center but is quickly cut off when the air traffic controller who answers says the center is busy dealing with a hijacking. According to author Lynn Spencer, Scoggins “calls New York Center to notify them that American 11 appears to be descending toward New York, most likely to land at JFK” International Airport. But the controller who takes the call snaps at him: “We’re too busy to talk. We’re working a hijack,” and then hangs up. According to Spencer, the New York Center controller is referring to Flight 175, but “Scoggins just figures that he’s talking about American 11. He has no idea that a second airliner is in crisis.” However, the timing of this call is unclear. If it is made while Flight 11 is descending toward New York, this would mean it occurs in the minutes before 8:46, when Flight 11 crashes (see 8:46 a.m. September 11, 2001). But in Spencer’s account, the call is made just after New York Center controller Dave Bottiglia notices that Flight 175’s transponder code has changed and he calls out to another controller, “I can’t get a hold of UAL 175 at all right now and I don’t know where he went to” (see 8:51 a.m.-8:53 a.m. September 11, 2001). (Spencer 2008, pp. 48-49) The transcript of radio communications between the New York Center and Flight 175 shows that this would mean Scoggins’s call occurs around 8:53 a.m.-8:54 a.m., about seven minutes after Flight 11 crashes. (New York Times 10/16/2001)

Employees at the American Airlines Southeastern Reservations Office in Cary, North Carolina, lose communication with Betty Ong, a flight attendant on the hijacked Flight 11. (American Airlines 9/11/2001, pp. 20-22; 9/11 Commission 7/24/2004, pp. 5-6)
Ong Stops Responding to Questions - For about the last 25 minutes, Ong has been on the phone with a number of employees at the reservations office, and has been providing them with information about the trouble on her plane. (9/11 Commission 8/26/2004, pp. 8) But now she stops responding to their communications. Nydia Gonzalez, one of the reservations office employees, continues questioning Ong. She says: “What’s going on Betty? Betty, talk to me. Betty, are you there? Betty?” Receiving no response, she asks her colleague Winston Sadler, who is also participating in the call, “Do you think we lost her?” On another phone line, Gonzalez immediately notifies a manager at the American Airlines System Operations Control center in Texas that contact with Ong has been lost (see 8:44 a.m. September 11, 2001). (American Airlines 9/11/2001, pp. 20-22; 9/11 Commission 8/26/2004, pp. 14)
Ong Asked Airline Employees to 'Pray for Us' - Toward the end of the call, Ong said repeatedly to the reservations office employees: “Pray for us. Pray for us.” (ABC News 7/18/2002) Gonzalez will say in an interview later today that Ong’s final words, before the call ends, were, “Oh my God, the flight, it’s going down, it’s going down.” (Federal Bureau of Investigation 9/11/2001, pp. 1-8) But in a subsequent interview, she will say that before the call ends, Ong “started to cry” and then her final words were, “Oh God, oh God, what is going on?” (Federal Bureau of Investigation 9/12/2001, pp. 69-71) The reservations office employees have lost communication with Ong by 8:44 a.m., according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 6) But according to a summary of phone calls from the hijacked flights presented at the 2006 trial of Zacarias Moussaoui, the call from Ong began at 8:18 a.m. and 47 seconds, and lasts exactly 27 minutes, meaning it ends at 8:45 a.m. and 47 seconds. (US District Court for the Eastern District of Virginia, Alexandria Division 7/31/2006) Flight 11 will crash into the World Trade Center less than a minute after that, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 7)

Amy Sweeney, a flight attendant on Flight 11, gives updates over the phone to Michael Woodward, an American Airlines flight services manager at Logan International Airport in Boston, as her plane approaches the World Trade Center, and then, after she reports that the plane is flying “very, very low,” the line goes dead. (Federal Bureau of Investigation 9/13/2001, pp. 1-2; 9/11 Commission 7/24/2004, pp. 6-7) Sweeney has been on the phone with the American Airlines flight services office at Logan Airport since 8:32 a.m., describing to Woodward the trouble on her plane (see (8:32 a.m.-8:44 a.m.) September 11, 2001). (9/11 Commission 8/26/2004, pp. 11)
Sweeney Says Plane Is 'in a Rapid Descent' - She now tells Woodward: “Something is wrong. We are in a rapid descent.” She says her plane is flying “all over the place.” (9/11 Commission 1/25/2004 pdf file; 9/11 Commission 8/26/2004, pp. 14) Around this time, Woodward tells Nancy Wyatt, another employee in the flight services office, that Sweeney has “started screaming that there’s something wrong with the airplane.” He adds: “In other words… [the original pilot is] not flying the airplane. They’re not flying the airplane.” (American Airlines 9/11/2001, pp. 34-41)
Sweeney Says Plane Is Flying 'Very Low' - Woodward asks Sweeney to look out of the window to see if she can determine where her plane is. (9/11 Commission 1/25/2004 pdf file; 9/11 Commission 8/26/2004, pp. 14) In an interview with the FBI a couple of days later, Woodward will say that Sweeney tells him: “I see water. I see buildings. We’re very, very low. Oh my God.” (Federal Bureau of Investigation 9/13/2001, pp. 1-2) In 2004, he will give a slightly different account, telling the 9/11 Commission that Sweeney says: “We are flying low. We are flying very, very low. We are flying way too low.” Seconds later she says, “Oh my God, we are way too low.” (9/11 Commission 1/25/2004 pdf file; 9/11 Commission 8/26/2004, pp. 14) Sweeney says “Oh my God” after taking “a very slow, deep breath,” Woodward will tell ABC News. She says these final words “[v]ery slowly, very calmly, very quietly. It wasn’t in panic,” Woodward will say.
Call Suddenly Cut Off - Woodward then hears what he will describe as “very, very loud static on the other end” of the line. (ABC News 7/18/2002) After a short time, the line goes dead. (Federal Bureau of Investigation 9/13/2001, pp. 1-2) Woodward looks up from the phone and tells everyone else in the office that the line has died. (Federal Bureau of Investigation 9/13/2001, pp. 3-4) Wyatt is on the phone with Ray Howland, an employee at the American Airlines System Operations Control center in Fort Worth, Texas, and has been passing on to him the information that Sweeney was providing to Woodward (see 8:40 a.m.-8:48 a.m. September 11, 2001). She now informs Howland, “Okay, we just lost connection” with Sweeney. (American Airlines 9/11/2001, pp. 34-41; et al. 9/7/2011, pp. 14 pdf file)
Flight Services Office Personnel Learn of Crash at WTC - Shortly after Sweeney’s call is cut off, Woodward’s operational manager, Craig Kopetz, will enter the flight services office and say that a plane has just crashed into the WTC. Woodward will not initially connect this news with the crisis he has been dealing with. (Federal Bureau of Investigation 9/13/2001, pp. 1-2; ABC News 7/18/2002) Those in the flight services office will then go to their command center. “Approximately 15 minutes later,” according to Elizabeth Williams, one of Woodward’s colleagues, the group will realize that “Flight 11 was the same flight which crashed into the WTC.” (Federal Bureau of Investigation 9/13/2001, pp. 3-4) The call between Sweeney and Woodward lasts “approximately 12 minutes” and ends at around 8:44 a.m., according to the 9/11 Commission. (9/11 Commission 2004, pp. 4; 9/11 Commission 8/26/2004, pp. 11, 14) But according to a summary of phone calls from the hijacked flights presented at the 2006 trial of Zacarias Moussaoui, the call began at 8:32 a.m. and 39 seconds, and lasts 13 minutes and 13 seconds, meaning it ends at 8:45 a.m. and 52 seconds. (US District Court for the Eastern District of Virginia, Alexandria Division 7/31/2006) Flight 11 crashes into the WTC less than a minute later, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 7)

An air traffic controller at the FAA’s Boston Center suggests that Flight 11 is going to crash into the World Trade Center. (The Learning Channel 8/20/2006) Flight 11 is heading southbound toward New York, descending at about 3,200 feet per minute. (National Transportation Safety Board 2/19/2002 pdf file) John Hartling, a controller at the Boston Center who has been monitoring it (see (8:34 a.m.) September 11, 2001), will later recall, “One of my fellow controllers on the other side of the room, I heard him say, ‘That airplane’s gonna hit the World Trade Center.’” (The Learning Channel 8/20/2006) Flight 11 will crash into the WTC at 8:46 a.m. (see 8:46 a.m. September 11, 2001). (National Transportation Safety Board 2/19/2002 pdf file)

The hole caused by the Flight 11 crash.The hole caused by the Flight 11 crash. [Source: Reuters]Flight 11 slams into the WTC North Tower (Building 1). Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. (CNN 9/12/2001; New York Times 9/12/2001; North American Aerospace Defense Command 9/18/2001; Cauchon 12/20/2001; Federal Emergency Management Agency 5/1/2002, pp. 1-10; Dwyer et al. 5/26/2002; Levin, Adams, and Morrison 8/12/2002; Associated Press 8/21/2002; Adcock 9/10/2002) The NIST report states the crash time to be 8:46:30. (National Institute of Standards and Technology 9/2005, pp. 19) The 9/11 Commission Report states the crash time to be 8:46:40. (9/11 Commission 7/24/2004, pp. 7) Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). (Dwyer et al. 5/26/2002) The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. (Cauchon 12/20/2001; National Institute of Standards and Technology 9/2005, pp. 20-22) The impact severs some columns on the north side of the North Tower. Each tower is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). (National Institute of Standards and Technology 9/2005, pp. 5-9, 20, 22) The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 percent. (National Institute of Standards and Technology 9/2005, pp. 6) The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” (National Institute of Standards and Technology 9/2005, pp. 107) According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. (National Institute of Standards & Technology 9/2005, pp. 189 pdf file) If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. (National Institute of Standards & Technology 9/2005, pp. xxxvi, 83 pdf file) Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). (National Institute of Standards and Technology 9/2005, pp. 23) According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).

Judy Martz.Judy Martz. [Source: Publicity photo]Emergency managers from around the US, including Federal Emergency Management Agency (FEMA) Director Joseph Allbaugh and representatives from the emergency management agencies of 47 states, are away from their home states at the time of the terrorist attacks, attending the annual conference of the National Emergency Management Association (NEMA) at a resort in Big Sky, Montana. The main focuses of the event have included the issues of domestic terrorism and weapons of mass destruction. (Janofsky 9/12/2001; DeMers 10/2001 pdf file) The conference began on September 8, and was originally planned to continue until September 12 (see September 8-11, 2001). (Natural Hazards Observer 3/2001; National Emergency Management Association 8/15/2001)
Emergency Managers Learn of Attacks - At 9:00 a.m., conference attendees are scheduled to participate in a series of sessions on domestic preparedness, which has been a key topic for NEMA over the past three years. (National Emergency Management Association 8/15/2001; DeMers 10/2001 pdf file) According to the New York Times, “One of the day’s main seminar topics was how to prepare for terrorist attacks.” (Janofsky 9/12/2001) However, numerous pagers go off as officials are notified of the events in New York. By the time officials gather around the television in the resort’s bar to see what is happening, the second plane has hit the World Trade Center (see 9:03 a.m. September 11, 2001) and the nature of the emergency is obvious. (Nagy 9/10/2002)
Emergency Managers Respond to Attacks - After the emergency managers at the conference see the coverage of the attacks on television, they “automatically organized themselves into particular groups to focus on transportation issues or to capture information,” Trina Hembree, the executive director of NEMA, will later recall. (Murphy 10/11/2001) The emergency managers, along with federal personnel and private-sector members, go about coordinating their jurisdictions’ responses to the attacks from the resort. Hotel employees add phone lines and equipment so as to enable communication and the tracking of events. A 24-hour emergency operations center is set up, and teams are organized to address specific areas, such as transportation and medical needs. The emergency managers monitor events and stay in contact with their agencies by phone, and also attend briefings at the resort, where they are updated on the national situation. (DeMers 10/2001 pdf file)
State of Emergency Declared in Montana - Partly due to concerns over the safety of the emergency management officials at the conference, Montana Governor Judy Martz declares a state of emergency. (Nagy 9/13/2001) Furthermore, roads to the Big Sky resort are closed, and security for the resort is provided by the local sheriff’s department and volunteer fire department, the Montana Highway Patrol, the Montana National Guard, and the FBI.
Arrangements Made to Fly Key Officials Home - The conference’s organizers arrange for military aircraft to fly state emergency management leaders back to their capitals. (Janofsky 9/12/2001; DeMers 10/2001 pdf file) Allbaugh and officials from several states that are directly involved in the attacks are flown home throughout the day (see (After 11:00 a.m.) September 11, 2001, (After 11:00 a.m.) September 11, 2001, and (After 4:30 p.m.) September 11, 2001), but others at the conference have to drive long distances back to their states.
Emergency Managers 'Not Where They Wanted to Be' - As one news report will later describe, when the attacks occur, “emergency managers were not where they wanted to be.” FEMA spokesman Mark Wolfson will note the inconvenient timing of the attacks, saying that FEMA officials do not know whether they were timed to catch emergency officials off guard. “That would be speculation,” he says. “But it is something that law enforcement investigators might be looking at.” (Nagy 9/13/2001; DeMers 10/2001 pdf file) NEMA is the professional association of state emergency management directors. (Natural Hazards Observer 3/2001) Hundreds of state emergency management officials, including almost all of the US’s state emergency management directors, and most of the senior FEMA staff are in Montana for its annual conference. (Nagy 9/13/2001; DeMers 10/2001 pdf file)

Personnel and aircraft at Barksdale Air Force Base in Louisiana are participating in the annual US Strategic Command (Stratcom) exercise Global Guardian (see 8:30 a.m. September 11, 2001) when the first crash at the World Trade Center is reported on television. (US Department of Defense 5/1997; Villafuerte 9/8/2002)
Nuclear Weapons Are Being Loaded onto Bombers - Global Guardian is based around the scenario of a rogue nation attacking the United States with nuclear weapons. At Barksdale, according to journalists Eric Schmitt and Thom Shanker, air crews taking part in the exercise have been “pulling nuclear bombs and missiles out of their heavily guarded storage sites and loading them aboard B-52s” this morning. Real, live nuclear weapons are being used, but “their triggers [are] not armed.” (Schmitt and Shanker 2011, pp. 22) “We were in the midst of this big annual exercise called Global Guardian. They loaded all the bombers, put the submarines out to sea, put the [intercontinental ballistic missiles] at nearly 100 percent,” Lieutenant General Thomas Keck, commander of the 8th Air Force at Barksdale, will later recall. “It was routine, you did it every year,” he will add. (Graff 9/9/2016)
Officers Realize America's Security Is at Risk - Colonel Mike Reese, director of staff for the 8th Air Force, is monitoring several television screens at the base as part of the exercise when he sees CNN cut into coverage of the first crash at the WTC, two minutes after it happens (see 8:48 a.m. September 11, 2001). He will see the second hijacked plane crashing into the WTC live on television at 9:03 a.m. (see 9:03 a.m. September 11, 2001). He will recall that at this point: “[W]e knew it wasn’t a mistake. Something grave was happening that put the nation’s security at risk.”
Exercise Participants Switch to Defending the Base - The New Orleans Times-Picayune will describe how awareness of the real attacks impacts those participating in the exercise, stating: “Immediately their focus turned to defense, securing Barksdale, Minot [North Dakota], and Whiteman [Missouri] air force bases, where dozens of aircraft and hundreds of personnel were involved in the readiness exercise ‘Global Guardian.’ The exercise abruptly ended as the United States appeared to be at war within its own borders.” (Villafuerte 9/8/2002)
Air Force Becomes Concerned about a Plane Being Crashed into the B-52s - The Air Force will be particularly concerned that terrorists might try to crash a hijacked plane into the B-52s with nuclear weapons on board that are on the tarmac at Barksdale. Although an attack of this kind would not set off a nuclear blast, it could cause a large explosion. “You would destroy half of Bossier City, Louisiana, with the explosions,” Al Buckles, Stratcom’s deputy director for operations, will comment. He will add: “That would have been a way to really cripple us. All these nuclear weapons were exposed.” (Liewer 9/9/2016) Four A-10s, aircraft not designed for air-to-air combat, from Barksdale’s 47th Fighter Squadron, will be placed on “cockpit alert,” the highest state of readiness for fighter pilots. “Within five minutes,” according to the Times-Picayune, “the A-10s, equipped only with high-intensity cannons, could have been launched to destroy unfriendly aircraft, even if it was a civilian passenger airliner.” Lieutenant Colonel Edmund Walker, commander of the 47th Fighter Squadron, and a novice pilot still in training will be sitting in their jets, ready to take off, when they are ordered back to the squadron office. They will be told they are no longer practicing. Walker will recall: “We had to defend the base against any aircraft, airliner, or civilian. We had no idea. Would it fly to the base and crash into the B-52s or A-10s on the flight line?” (Villafuerte 9/8/2002) When Air Force One with President Bush on board takes off from Sarasota, Florida, at around 9:55 a.m. (see 9:54 a.m. September 11, 2001), it will initially have no fixed destination. But after a short time, it will begin heading toward Barksdale Air Force Base and land there at 11:45 a.m. (see 11:45 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 39, 325)

Clyde Vaughn.Clyde Vaughn. [Source: Scott Davis / US Army]General John Keane, vice chief of staff of the Army, learns that a plane has crashed into the World Trade Center and consequently orders that the Army Operations Center (AOC) at the Pentagon be brought up to full manning. Keane is in his office at the Pentagon when one of his sergeants rushes into the room, tells him something terrible has happened in New York, and turns on the television. Keane sees the reports stating that a plane has hit the WTC and is immediately suspicious. “I noticed it was a blue-sky day and [thought] you could not hit the WTC by accident,” he will later recall. “I knew in 1993 terrorists had tried to bomb the WTC and bring it down from an underground parking garage,” he will say (see February 26, 1993). Therefore, he will recall, “I sensed it instinctively, what had happened, that this was a terrorist act.” He calls Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, who is in his office at the Pentagon, and tells him to bring the AOC up to full manning. (Baier 9/12/2011; Keane 9/10/2016; Swift 9/11/2016) The AOC, located in the basement of the Pentagon, is “the place that people will migrate” to during an emergency, according to Brigadier General Clyde Vaughn, the Army’s deputy director of operations, readiness, and mobilization. It is equipped with state-of-the-art communications equipment and television sets for monitoring news coverage. (Vogel 8/25/1995; Vaughn 2/12/2002; Schwab and Jewell 9/2004) Keane will subsequently see the second hijacked plane crashing into the WTC on television (see 9:03 a.m. September 11, 2001). Sometime after that, Chiarelli will call him to confirm that the AOC is fully manned (see Shortly Before 9:37 a.m. September 11, 2001). (Keane 9/10/2016) The AOC will remain manned throughout today’s attacks and their aftermath. Keane will go to it after the Pentagon is attacked, to provide leadership and guidance (see (Shortly After 9:37 a.m.) September 11, 2001). (Goldberg et al. 2007, pp. 135; Christopher N. Koontz 2011, pp. 56 pdf file; Baier 9/12/2011) The Army’s Crisis Action Team, whose members assemble in the AOC, will be activated sometime after Keane orders Chiarelli to bring the operations center up to full manning (see (Shortly After 9:03 a.m.) September 11, 2001). (Chiarelli 2/5/2002; Rossow 2003, pp. 64-65)

An announcement goes out over the public address system in the South Tower of the World Trade Center, telling workers that an incident has occurred in the other WTC tower and their building is safe, and advising them to stay in—or return to—their offices, rather than evacuate. (Moore and Cauchon 9/2/2002; 9/11 Commission 7/24/2004, pp. 287-288) After Flight 11 hit the North Tower at 8:46 a.m. (see 8:46 a.m. September 11, 2001), many people in the South Tower were unaware of what had happened. “Some believed an incident had occurred in their building; others were aware that a major explosion had occurred on the upper floors of the North Tower,” the 9/11 Commission Report will state. As a result, many workers decided to leave the South Tower. (9/11 Commission 7/24/2004, pp. 287) As they do so, an announcement is made over the public address system.
Announcement Says South Tower Is Secure - Brian Clark, an executive with Euro Brokers who also serves as a fire warden and is on the 84th floor of the South Tower, will later describe this announcement. “First, the strobe lights flashed, as they did during their normal fire drills,” he will say. “The alarm system gave a little bit of a whoop, whoop… to alert you to an announcement about to be made. Then the very familiar voice, the one we heard all the time, came over the system.” Clark will recall that the voice says: “Your attention, please, ladies and gentlemen. Building 2 [i.e. the South Tower] is secure. There is no need to evacuate Building 2. If you are in the midst of evacuation, you may use the re-entry doors and the elevators to return to your office. Repeat, Building 2 is secure.” (Clark 4/30/2002; Dwyer and Flynn 2005, pp. 72) The announcement is made two or possibly three times, according to USA Today. (Moore and Cauchon 9/2/2002) Florence Engoran, a credit analyst working in the South Tower, will recall it being made “[o]ver and over and over again.” (DiMarco 2007, pp. 50)
Announcement May Lead to Hundreds of Deaths - Many people in the South Tower remain on their floors after hearing the announcement, while others who were leaving the building turn around and head back upstairs. (9/11 Commission 7/24/2004, pp. 289) USA Today will suggest that the announcement therefore “may have led to the deaths of hundreds of people.” (Moore and Cauchon 9/2/2002) According to the National Institute of Standards and Technology, of those who die in the South Tower, only 11 are below where the plane hits the tower at 9:03 a.m. (see 9:03 a.m. September 11, 2001), and 619 are in or above the point of impact. (National Institute of Standards and Technology 9/2005, pp. 44)
Announcement Goes against Protocol - The announcement is later believed to have been made by Philip Hayes, a deputy fire safety director at the WTC, who is manning the fire command desk in the lobby of the South Tower. Fire safety directors are trained to read scripted announcements from a loose-leaf binder. But, according to the 9/11 Commission Report, the advice given in the announcement, for people to stay in, or return to, their offices, “did not correspond to any existing written protocol.”
Security Manager Decided to Instruct Workers Not to Evacuate - The 9/11 Commission Report will also state, “We do not know the reason for the announcement, as both [Hayes] and the director of fire safety for the WTC complex perished in the South Tower’s collapse.” (Moore and Cauchon 9/2/2002; 9/11 Commission 7/24/2004, pp. 288; Dwyer and Flynn 2005, pp. 26, 72) However, George Tabeek, a security manager with the Port Authority of New York and New Jersey, will admit having made the decision to instruct South Tower workers to return to their offices (see Shortly After 8:46 a.m. September 11, 2001). (Walmsley 9/10/2011) Some security officials in the South Tower instruct workers, in person, to return upstairs, rather than evacuate (see (8:47 a.m.-9:02 a.m.) September 11, 2001). But finally, about a minute before Flight 175 hits the South Tower, an instruction will be broadcast over the public address system informing workers that they can begin an evacuation if conditions warrant it (see 9:02 a.m. September 11, 2001). (Vulliamy 9/16/2001; 9/11 Commission 7/24/2004, pp. 289)

A typical F-15.A typical F-15. [Source: US Air Force]Radar data will show that the two F-15s scrambled from Otis Air National Guard Base in Cape Cod, Massachusetts, are airborne by this time. (Graham 9/15/2001; North American Aerospace Defense Command 9/18/2001; 9/11 Commission 7/24/2004, pp. 20) It is now eight minutes since the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) ordered that the jets be launched (see 8:45 a.m. September 11, 2001). (Bronner 8/1/2006) It is 40 minutes since air traffic controllers had their last communication with Flight 11 (see 8:13 a.m. September 11, 2001), and 28 minutes since they became certain that the aircraft was hijacked (see (8:25 a.m.) September 11, 2001). Flight 11 crashed into the World Trade Center seven minutes ago (see 8:46 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 7, 19 and 459)
Commander Wants Fighters Sent to New York - In Rome, New York, NEADS has just received news of the plane hitting the WTC (see 8:51 a.m. September 11, 2001). Major Kevin Nasypany, the facility’s mission crew commander, is asked what to do with the Otis fighters. He responds: “Send ‘em to New York City still. Continue! Go! This is what I got. Possible news that a 737 just hit the World Trade Center. This is a real-world.… Continue taking the fighters down to the New York City area, JFK [International Airport] area, if you can. Make sure that the FAA clears it—your route all the way through.… Let’s press with this.” (Bronner 8/1/2006) Yet there will be conflicting reports of the fighters’ destination (see (8:53 a.m.-9:05 a.m.) September 11, 2001), with some accounts saying they are directed toward military-controlled airspace off the Long Island coast. (Filson 2003, pp. 56-59; 9/11 Commission 6/17/2004)

An air traffic controller at the FAA’s Boston Center directs the two fighter jets that took off from Otis Air National Guard Base in response to the hijacked Flight 11 toward a new heading, based on instructions he has just received from NORAD’s Northeast Air Defense Sector (NEADS).
NEADS Gave New Heading for Fighters - The Boston Center controller, who is working at the Cape Sector radar position, has just been contacted by someone from NEADS. The caller from NEADS, referring to the two fighters from Otis Air Base, said, “The heading that we gave him on, I guess, is a bad heading.” (Federal Aviation Administration 9/11/2001; 9/11 Commission 2004) (The original flight strip for the fighters gave a destination of New York’s JFK International Airport. (9/11 Commission 9/22/2003 pdf file) ) The caller said the fighters’ target was “now south of JFK,” and added, “Can you direct the Panta flight [i.e. the two Otis fighters] towards that now?” The controller replied: “If I’m talking to him, I don’t know where that target [is]. I don’t even see the target at all.” (Federal Aviation Administration 9/11/2001) The “target,” Flight 11, crashed into the World Trade Center at 8:46 a.m. (see 8:46 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 7) However, the caller explained that NEADS had just talked to Colin Scoggins, the military liaison at the Boston Center, and Scoggins said the target was “south of JFK now.” The caller therefore reiterated, “We want to get [the Otis fighters] headed in that direction.” The controller confirmed, “I’ll do that.”
Controller Passes on New Heading to Pilot - Seconds later, Lieutenant Colonel Timothy Duffy, one of the pilots of the two fighters out of Otis Air Base, checks in with the Boston Center controller. Duffy says, “Boston Center, Panta 45 with you out of 13-5 for 290.” (Federal Aviation Administration 9/11/2001; 9/11 Commission 2004) (“Panta 45” is Duffy’s call sign. (Spencer 2008, pp. 113) ) The controller tells Duffy, “Panta 45, roger, fly heading of 260.” Duffy confirms the new heading. The controller then instructs, “Maintain block 290.” Duffy confirms, “Six zero on the heading, climbing to flight level [of] 290.” The controller will then tell Duffy that Flight 11 has crashed into the WTC (see 8:55 a.m. September 11, 2001). (Federal Aviation Administration 9/11/2001)

Captain Deborah Loewer.
Captain Deborah Loewer. [Source: Military Sealift Command]Navy Captain Deborah Loewer, director of the White House Situation Room, tells President Bush a plane has crashed into the World Trade Center when his limousine arrives at the Emma E. Booker Elementary School in Sarasota, Florida, where he is going to attend a reading demonstration. (Associated Press 11/26/2001; Lance 8/17/2003) Loewer learned about the crash when Rob Hargis, the senior duty officer in the Situation Room, called her as she was being driven to the school and told her what had happened (see (Between 8:48 a.m. and 8:55 a.m.) September 11, 2001). (Bohn 8/29/2011; Priess 2016, pp. 239-240) As soon as the president’s motorcade arrives at the school (see (8:55 a.m.) September 11, 2001), she runs toward Bush’s limousine to pass on the news to the president. (Lance 8/17/2003) She approaches Bush and Andrew Card, his chief of staff, as they are walking toward the school’s entrance. She says to Bush, “Mr. President, the Situation Room is reporting that one of the World Trade Center towers has been hit by a plane.” She adds, “This is all we know.” She also says experience has taught her that first reports are often wrong. Bush replies, “Thank you, Captain” as he continues making his way toward the school’s entrance and then says, “Keep me informed.” Loewer is “the first person to inform President Bush that terrorism had struck New York City,” according to the Associated Press. (Associated Press 11/26/2001; Stafford 9/9/2011; Bohn 2015, pp. 214; Priess 2016, pp. 240) However, some accounts will claim that either Karl Rove, Bush’s senior adviser, or Card is the first person to tell the president a plane has crashed into the WTC (see (Shortly After 8:55 a.m.) September 11, 2001). (Sammon 2002, pp. 41-42; Rove 2010, pp. 249-250; Graff 9/9/2016) After passing on the news about the crash, Loewer goes to the holding room next to the classroom where Bush is going to listen to some children reading. There, she will learn about Flight 175 crashing into the WTC when the attack occurs, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). (Bohn 2015, pp. 214; Priess 2016, pp. 240-241)

Paul Worcester.Paul Worcester. [Source: Paul Blackmore / Cape Cod Times]Senior commanders at Otis Air National Guard Base in Cape Cod, Massachusetts, become aware of the attacks on the World Trade Center from television coverage, and one commander then orders the base’s battle staff to assemble. The commanders have just been in the first of the base’s regular Tuesday morning meetings, which ended at 8:55 a.m. They are taking a short break before the next meeting, which is scheduled for 9:00 a.m., and are apparently unaware that a plane has crashed into the WTC.
Wing Commander Sees Burning WTC on Television - One of those in the meeting was Lieutenant Colonel Paul Worcester, the logistics group commander of the 102nd Fighter Wing, which is based at Otis. As Worcester walks past the break room he notices that everyone inside it is fixated on the television. He goes in to find what they are watching and gets his first sight of the coverage of the burning North Tower. Worcester finds it odd that a plane could have hit the WTC, and thinks to himself: “On such a clear day, planes don’t just go astray. That just doesn’t happen.” Although he is aware that the base’s two F-15s that are kept on alert have been scrambled in response to a suspected hijacking (see 8:46 a.m. September 11, 2001), he does not connect this with what he is seeing on television.
Commanders See Second Attack - Worcester is joined in the break room by more of the senior commanders. They watch as the live television coverage shows Flight 175 crashing into the South Tower (see 9:03 a.m. September 11, 2001), and all of them then realize that America is under attack. One commander immediately shouts out, “We need to go to battle staff!” The senior commanders disperse and head toward the adjacent operations building, where they will reconvene in the battle cab of the installation operations center (see Shortly After 9:03 a.m. September 11, 2001). A voice sounds out over the base’s loudspeakers: “The commander has ordered the 102nd core battle staff to assemble. Please report to the operations building immediately.”
Unit Mobilizes for War - Subsequently, as author Lynn Spencer will describe: “Under the leadership of the [102nd Fighter] Wing commander, the various subordinate group commanders cross-brief on scramble activity, training flight issues, available munitions, personnel available to begin uploading more fighters to combat-ready status, security force increases, and more. In short, they begin to mobilize the wing for war, keeping NEADS [NORAD’s Northeast Air Defense Sector] in the loop on their preparations.” (Spencer 2008, pp. 87-88, 153-154)
Base Learned of First Hijacking 20 Minutes Earlier - The 102nd Fighter Wing of the Massachusetts Air National Guard, which is based at Otis Air Base, is responsible for protecting the Northeast United States, including New York, Washington, and Boston. Its mission includes defending the region against terrorist attacks. (Kinsella and Dennehy 9/12/2001; Kinsella 9/12/2001) On a typical day, it has about a dozen pilots on duty. (Dennehy 9/15/2001) It is equipped with 18 F-15 fighter jets, two of which are kept on 24-hour alert, ready to be in the air within five minutes of being called upon. (Johnson 9/15/2001; Dennehy 9/21/2001) These were the two jets that launched at 8:46 a.m. in response to the hijacking of Flight 11. (9/11 Commission 7/24/2004, pp. 20) The base was notified about this first hijacking shortly after 8:34 a.m. (see (8:36 a.m.-8:41) September 11, 2001). (Spencer 2008, pp. 27-28) Why the senior commanders did not initiate their crisis response at that time is unclear.

The jet fuel that spilled from Flight 11 when it hit the North Tower (see 8:46 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which investigates the collapses, will say “The initial jet fuel fires themselves lasted at most a few minutes.” (National Institute of Standards and Technology 9/2005, pp. 183) Engineering professor Forman Williams will say the jet fuel “burned for maybe 10 minutes.” (Chertoff et al. 3/2005) Flight 11, a Boeing 767, had a fuel capacity of 23,980 gallons, but was only carrying about 10,000 gallons when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and a comparable amount was consumed in the fireballs outside the building. Therefore, approximately 7,000 gallons splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually have fewer combustibles than some other similar spaces due to the small number of interior walls and limited bookshelf space. NIST will later find that only three of sixteen perimeter columns it recovers reached a temperature of 250°C and neither of the two core columns it retrieves reached this temperature. NIST will also find that none of the samples it acquires reaches a temperature above 600°C (see August 27, 2003). Although steel does not melt until its temperature is about 1,600°C, it may begin to lose significant strength at over 500°C. (National Institute of Standards and Technology 9/2005, pp. 20, 29, 24, 77) The jet fuel will also burn up in the South Tower about 10 minutes after it is hit (see 9:13 a.m. September 11, 2001).

A special radio transmitter that is carried by aircraft and designed to go off automatically if a plane crashes is activated in the New York area, several minutes before Flight 175 hits the World Trade Center. David Bottiglia, an air traffic controller at the FAA’s New York Center, receives information from one of the aircraft he is monitoring. A few seconds before 8:59 a.m., the pilot of US Airways Flight 583 tells him, “I hate to keep burdening you with this stuff, but now we’re picking up another ELT on 21.5.” (Federal Aviation Administration 9/11/2001, pp. 37 pdf file; 9/11 Commission 10/1/2003 pdf file; 9/11 Commission 2004) An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically begin transmitting a distress signal if a plane should crash, so as to help search and rescue attempts at locating the downed aircraft. (Federal Aviation Administration 3/23/1990; US Department of the Army 8/12/2008, pp. E-6 pdf file; Aircraft Owners and Pilots Association 1/22/2009) “21.5” refers to the emergency frequency of 121.5 megahertz that ELTs transmit their distress signals on. (Aircraft Electronics Association 2009, pp. 36 pdf file) While the pilot’s information would mean an ELT is activated at around 8:58 a.m., Flight 175 will crash into the WTC several minutes later, at 9:03 a.m. and 11 seconds (see 9:03 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 8) And yet there are no reports of an ELT going off at the time of the crash itself. The pilot of Flight 583 earlier on informed Bottiglia of another ELT signal, which had been transmitted shortly before Flight 11 hit the WTC (see 8:44 a.m. September 11, 2001). (New York Times 10/16/2001; 9/11 Commission 10/1/2003 pdf file)

Mike Morell, President Bush’s CIA briefer, calls the CIA’s operations center to see if anyone there knows more about what has happened at the World Trade Center and is told that the WTC was hit by a large commercial airliner. (Morell 9/2006 pdf file; Morell and Harlow 2015, pp. 48) Morell learned that a plane had crashed into the WTC as he was being driven to the Emma E. Booker Elementary School in Sarasota, Florida, where Bush is going to attend a reading event. White House press secretary Ari Fleischer, who was in the same vehicle as him, received a pager message stating what had happened and then exclaimed, “A plane just hit the World Trade Center” (see (Between 8:48 a.m. and 8:55 a.m.) September 11, 2001). (Bamford 2004, pp. 17; Graff 9/9/2016) Fleischer asked Morell if he knew anything about the incident. “As the in-house intelligence officer, Morell was the man they looked to for the scoop when something startling happened,” journalist and author Mark Bowden will comment. (Bowden 2012, pp. 3) The CIA officer knew nothing about the incident but said he would make some calls to inquire about it.
CIA Officer Thought the Crash Was an Accident - Morell initially assumed the crash was an accident. “The image in my mind,” he will later recall, “was of a small plane losing its way in a storm or fog and hitting the World Trade Center. I figured the death toll would include only two or three people on the plane and perhaps a few more in offices at the point of impact.” All the same, after entering the school, he calls the operations center at CIA headquarters in Langley, Virginia, to see if anyone there knows more about the crash. He assumes someone there likely will because, he will write, “I had come to rely on the group of hard-working officers in the center, both to set aside for me key pieces of overnight reporting and to answer my many questions.”
CIA Officer Is Told a Large Plane Hit the WTC - However, the duty officer Morell talks to is able to tell him little more than what he already knows. The one new detail the duty officer provides, Morell will recall, is that “the initial reports indicated that the plane [that hit the WTC] was a large commercial jet.” “My hope that this was not terrorism started to fade,” he will write. Morell then walks into the holding room next to the classroom where Bush is going to listen to some children reading and notices that the time is 9:00 a.m. Minutes later, he will learn about Flight 175 crashing into the WTC (see 9:03 a.m. September 11, 2001) and realize immediately that the incident is a “deliberate act of terrorism.” (Morell 9/2006 pdf file; Morell and Harlow 2015, pp. 47-48)

Matt Swanson.Matt Swanson. [Source: Iowa State University]The Air Force’s Crisis Action Team (CAT) at the Pentagon is activated and will go on to play a key role in the Air Force’s response to the terrorist attacks. (Brown 9/19/2001; Prospectus 9/2006, pp. 3-6 pdf file) The CAT, which is under the command of the Air Force chief of staff, is a “disaster response group,” which, according to the Dover Post, “coordinates Air Force reaction to anything that might be a threat to the United States.” (Brown 9/19/2001; Federal Aviation Administration 9/11/2011) It carries out its activities in the Air Force Operations Center, in the basement of the Pentagon’s C Ring. (Yackel 12/2001; Sharp 9/11/2003) Its usual first in charge is away today and so Lieutenant Colonel Matt Swanson, its second in command, has to take their place supervising emergency operations for the Air Force. (Prospectus 9/2006, pp. 3-6 pdf file)
Crisis Team Becomes 'Eyes and Ears' of the Air Force - Prior to the Pentagon being hit at 9:37 a.m. (see 9:37 a.m. September 11, 2001), according to the Defense Department’s book about the Pentagon attack, “Members of the Air Force Crisis Action Team [have] already begun to assemble [in the Operations Center] for a 10:00 a.m. briefing.” This is because “one of their responsibilities [is] to work with the Army to provide assistance to civil authorities in New York.” (Goldberg et al. 2007, pp. 136) Major Donna Nicholas arrives in the Operations Center to assist the CAT at some time after 9:03 a.m., when the second hijacked plane crashes into the World Trade Center (see 9:03 a.m. September 11, 2001). When she gets there, someone tells her, “Just so you know, we’re considering that we’re under attack.” After arriving at her station and pulling out emergency checklists, she will later recall, Nicholas finds the area around her is “a flurry of activity as Air Force officials worked to gather information, both from the media and from their own intelligence sources.” (Brown 9/19/2001) The CAT becomes “the eyes and ears of the Air Force” as it responds to the terrorist attacks, according to Major Harry Brosofsky, who will go to the Operations Center to assist the CAT after the Pentagon is attacked. (Yackel 12/2001)
Air Force Leaders Only Join Crisis Team after Pentagon Attack - It is unclear when exactly the CAT is activated. Nicholas is told it has been activated at “about 9 a.m.,” according to the Dover Post. (Brown 9/19/2001) Tim Green, assistant executive to the Air Force chief of staff, will say that after senior Air Force officials who are together in a staff meeting (see (9:00 a.m.-9:20 a.m.) September 11, 2001) see the second crash at the WTC at 9:03 a.m., they “set up a Crisis Action Team down in our Operations Center and they began working immediately.” (Condon 4/2/2002) However, senior officials such as General John Jumper, the Air Force chief of staff, and James Roche, the secretary of the Air Force, will only head to the Operations Center to assist the response from there after 9:37 a.m., when the Pentagon is hit (see Shortly After 9:37 a.m. September 11, 2001). (Sharp 9/11/2003; Hebert 9/2011 pdf file) Swanson—the man in charge of the CAT today—will say he receives a phone call in his office at the Pentagon at some time after the second WTC tower is hit, in which he is told he has to go and join the CAT. However, he will apparently only reach the Operations Center to do so after the Pentagon is attacked: He will say that when he arrives, he is greeted by Jumper and Roche, and these two men only get there after the Pentagon is hit (see After 9:37 a.m. September 11, 2001). (Prospectus 9/2006, pp. 3-6 pdf file)

An announcement is made over the public address system in the South Tower of the World Trade Center, advising workers that they can begin an orderly evacuation of the building if conditions warrant it. (Dwyer 5/17/2004; 9/11 Commission 7/24/2004, pp. 289) A previous announcement over the public address system instructed people in the South Tower to stay in, or return to, their offices, rather than evacuate (see (8:50 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 287-288; Dwyer and Flynn 2005, pp. 72) The new announcement begins: “May I have your attention, please. Repeating this message: the situation occurred in Building 1 [i.e. the North Tower].” The announcer then says, “If the conditions warrant on your floor, you may wish to start an orderly evacuation.” (Dwyer 5/17/2004) The announcement is presumably made by Philip Hayes, the deputy fire safety director on duty at the fire command desk in the lobby of the South Tower. A button at the desk enables fire safety directors to deliver announcements over the public address system. (Dwyer and Flynn 2005, pp. 26)
Identity of Person Who Ordered Evacuation Unclear - The new advice, for tenants to evacuate, does “not correspond to any prewritten emergency instruction,” according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 289) It is unclear who told Hayes to make the announcement giving this advice. George Tabeek, the Port Authority’s security manager for the WTC, contacted the fire command desks in the Twin Towers immediately after Flight 11 hit the North Tower, with instructions about what to do. His orders for Hayes, however, were to “keep people inside the South Tower” (see Shortly After 8:46 a.m. September 11, 2001). (Grant 9/6/2011)
Police Commander Called for Evacuation of WTC - Captain Anthony Whitaker, the Port Authority Police Department (PAPD) commanding officer at the WTC, called for the evacuation of the WTC at 9:00 a.m. (see 8:59 a.m.-9:02 a.m. September 11, 2001). However, his instruction was given over PAPD radio channel W, “which could not be heard by the deputy fire safety director in the South Tower,” according to the 9/11 Commission Report. (Murphy 2002, pp. 184-185; 9/11 Commission 7/24/2004, pp. 293; National Institute of Standards and Technology 9/2005, pp. 201) Furthermore, according to the Port Authority, deputy fire safety directors do not generally take direct orders from the PAPD under the regular chain of command. Therefore, the 9/11 Commission Report will state, it is “not known if [Hayes] received the order by the PAPD to evacuate the complex.” (9/11 Commission 7/24/2004, pp. 544)
Fire Department Responsible for Ordering Evacuations - According to New York Times reporters Jim Dwyer and Kevin Flynn, “The authority to order an evacuation during a fire normally rests with the fire department.” (Dwyer and Flynn 2005, pp. 79) In a phone call with his counterpart in the North Tower, at 8:49 a.m., Hayes in fact said he would wait to hear from “the boss from the fire department or somebody” before ordering an evacuation of the South Tower (see 8:49 a.m. September 11, 2001). (Port Authority of New York and New Jersey 9/11/2001 pdf file; 9/11 Commission 7/24/2004, pp. 287; Dwyer and Flynn 2005, pp. 27) But whether someone from the fire department told Hayes to order an evacuation is unknown. It is also unclear how long announcements, advising an evacuation, continue for. Hayes and his counterpart in the North Tower are “making announcements that the situation was serious and that occupants should evacuate immediately” for “[a]s long as the [fire alarm system] was still operational,” according to Fire Engineering magazine. (Murphy 11/1/2002) However, the 9/11 Commission Report will state, “Evidence suggests that the public address system [in the South Tower] did not continue to function after the building was hit.” This would mean no announcements go out after 9:03 a.m., when Flight 175 hits the tower (see 9:03 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 295) By the time the South Tower collapses (see 9:59 a.m. September 11, 2001), out of around 8,540 people who were originally in the building, 7,940 (93 percent) have made it out and will survive, according to the National Institute of Standards and Technology. (National Institute of Standards and Technology 9/2005)

Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter.Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter. [Source: WABC 7/ Salient Stills]Flight 175 hits the South Tower of the World Trade Center (Tower Two). Seismic records pinpoint the time at six seconds before 9:03 a.m. (rounded to 9:03 a.m.). Hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, Mohand Alshehri, Hamza Alghamdi, and Ahmed Alghamdi presumably are killed instantly, and many more in the tower will die over the next few hours. (New York Times 9/12/2001; CNN 9/12/2001; CNN 9/17/2001; North American Aerospace Defense Command 9/18/2001; Cauchon 12/20/2001; Federal Emergency Management Agency 5/1/2002, pp. 1-10; Dwyer et al. 5/26/2002; Associated Press 8/21/2002; Moore and Cauchon 9/2/2002) According to the NIST report, the crash time is 9:02:59. (National Institute of Standards and Technology 9/2005, pp. 38) According to the 9/11 Commission Report, the crash time is 9:03:11. (9/11 Commission 7/24/2004, pp. 8) Millions watch the crash live on television. The plane strikes the 77th through 85th floors in the 110-story building. Approximately 100 people are killed or injured in the initial impact; 600 people in the tower eventually die. The death toll is far lower than in the North Tower because about two-thirds of the South Tower’s occupants have evacuated the building in the 17 minutes since the first tower was struck. (Cauchon 12/20/2001; National Institute of Standards and Technology 9/2005, pp. 5-9, 41) The combined death toll from the two towers is estimated at 2,819, not including the hijackers. (Associated Press 8/21/2002) The impact severs some columns on the south side of the South Tower. Each of the Twin Towers is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which is traveling at an estimated speed of around 500 mph (see October 2002-October 2005), severs 33 of the building’s 236 perimeter columns and damages another one. (National Institute of Standards and Technology 9/2005, pp. 39) The perimeter columns bear about half of the tower’s weight, so the damage to them reduces the tower’s ability to bear gravity loads by about 7.1 percent. (National Institute of Standards and Technology 9/2005, pp. 6) The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may be able to damage the core even after crashing through the exterior wall (see 8:46 a.m. September 11, 2001). (National Institute of Standards and Technology 9/2005, pp. 107) According to NIST’s base case model, five of the core columns are severed and another five suffer some damage. (National Institute of Standards & Technology 9/2005, pp. 235 pdf file) This may reduce the tower’s ability to bear loads by a further approximately 8 percent, meaning that the aircraft impact accounted for a loss of about 15 percent of the building’s strength. This damage will be cited as an event contributing to the building’s collapse after 9/11 (see October 23, 2002 and October 19, 2004). NIST’s base case estimate of damage to the North Tower’s core will be similar, even though the aircraft impact there was dissimilar (see 8:46 a.m. September 11, 2001). Flight 11 hit the North Tower’s core head on, whereas Flight 175 only hits the corner of the South Tower’s core. (National Institute of Standards and Technology 9/2005, pp. 20-23, 38-41) In addition, some of the fireproofing on the steel columns and trusses may be dislodged (see 8:46 a.m. September 11, 2001). (National Institute of Standards & Technology 9/2005, pp. xxxvi, 83 pdf file) Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but the National Institute of Standards and Technology (NIST) will try to estimate the damage to fireproofing using a series of computer models. Its severe case model (see (October 2002-October 2005)) will predict that 39 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 80,000 ft2 of floor area, the equivalent of about two floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). (National Institute of Standards and Technology 9/2005, pp. 41) According to NIST, less fireproofing is stripped from the North Tower (see 8:46 a.m. September 11, 2001).

The Army Operations Center at the Pentagon.The Army Operations Center at the Pentagon. [Source: Soldiers]The Army’s Crisis Action Team (CAT) at the Pentagon is activated in response to the attacks on the World Trade Center. It is activated on the orders of Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization.
General Instructed Colleague to Activate Crisis Team - At around 9:00 a.m., while he was preparing to go to a scheduled meeting, Chiarelli was called by Major General Julian Burns, deputy chief of staff for operations of the US Army Forces Command. Burns asked him if he had seen what had happened at the WTC on the news. Chiarelli looked up at the muted television in his office and then, after turning up the volume, watched the coverage of the crash at the WTC on CNN. He also called to his office Lieutenant Colonel Kevin Stramara, his chief of operations, who is responsible for the CAT. When Stramara arrived, Chiarelli told him, “We need to look at standing up the CAT because I believe we’ve got ourselves a possibility of a mass casualty [incident].” Although Chiarelli was uncertain whether what happened at the WTC had been a terrorist attack, he told Stramara: “Kevin, it’s time to activate the CAT. Get it set up.”
General Said Pentagon Had to Be a Potential Target - As Stramara was about to leave the room, the two men saw the TV coverage of the second hijacked plane, Flight 175, crashing into the WTC (see 9:03 a.m. September 11, 2001). Realizing this was a terrorist attack, Chiarelli pointed out, “If there are other aircraft up there that have been hijacked or if there are other aircraft getting ready to do this, this building [i.e. the Pentagon] has got to be a target.” He asked Stramara, “Who has responsibility for this building?” Stramara responded: “I don’t know. I will check, but first I’ll stand up the CAT.” (Chiarelli 2/5/2002; Lofgren 2011, pp. 95-97)
Crisis Team Assembles in Army's 'Command and Control Center' - The CAT, according to author Robert Rossow, is “an organization of subject matter experts from throughout the Army staff who assemble in times of emergency in a special area within the AOC”—the Army Operations Center. (Rossow 2003, pp. 64) The AOC is located in the basement of the Pentagon, inside a bunker reinforced by steel and concrete 60 feet below the parking lot, and is equipped with state-of-the-art communications equipment, as well as television sets for monitoring news coverage. Chiarelli will describe it as “the Army’s command and control center.” (Vogel 8/25/1995; Schwab and Jewell 9/2004) It is “the place that people will migrate” to during an emergency, according to Brigadier General Clyde Vaughn, the Army’s deputy director of operations, readiness, and mobilization. (Vaughn 2/12/2002)
Crisis Team Members Are Summoned to Operations Center - When the CAT is activated, according to Rossow, its members “are called to the AOC to man their battle stations.” (Rossow 2003, pp. 64) A piece of equipment called a “dialogic machine” sends out a telephonic alert to summon Army personnel to join the CAT. The machine automatically calls these people and gives them a prerecorded message, instructing them to report immediately to the CAT floor. (Chiarelli 2/5/2002; Lofgren 2011, pp. 100) Their mission, according to Rossow, is then “to provide information from their organizations and work issues within their particular area of expertise.” (Rossow 2003, pp. 64)
Crisis Team Is Activated to Provide Assistance in New York - Chiarelli will subsequently be phoned by General Eric Shinseki, the Army chief of staff, and will only head to the AOC to join the CAT after the call ends (see (Shortly Before 9:37 a.m.) September 11, 2001). (Chiarelli 2/5/2002; Lofgren 2011, pp. 98) He will tell Shinseki that he has activated the CAT to provide assistance in New York if requested by state and local officials, since he anticipates that the disaster at the WTC will require significant rescue, firefighting, and recovery efforts. (Goldberg et al. 2007, pp. 134) The CAT will be “formally stood up” at 9:43 a.m., according to Rossow (see 9:43 a.m. September 11, 2001). (Rossow 2003, pp. 66) It will become “a focal point for all Pentagon activities,” according to Lieutenant Colonel Richard Kotch, who is working in the AOC this morning. (Cohn 9/8/2011) Army officers are in fact currently preparing for a CAT exercise, which is scheduled to take place during the forthcoming week, based on the scenario of a plane crashing into the WTC (see (September 4, 2001)). (Chiarelli 2/5/2002; Lofgren 2011, pp. 96-97)

Gary Walters.Gary Walters. [Source: C-SPAN]Gary Walters, the chief White House usher, and a few of his colleagues take the time to clear up the White House grounds ready for when President Bush returns, and even continue with the task after the White House is evacuated. Earlier this morning, many White House staffers were busy preparing for the annual Congressional picnic, which was scheduled to take place this evening (see 8:30 a.m. September 11, 2001). About 170 to 180 picnic tables have been set up on the South Lawn for the event. After he learns that a second plane has crashed into the World Trade Center (see 9:03 a.m. September 11, 2001), Walters decides to start moving the picnic tables off the lawn so Bush’s helicopter will be able to land on the grounds when the president returns to the White House. (National Journal 8/31/2002; Walters 4/4/2006; Peter Schnall 7/12/2016)
Usher Arranges to Clear the Lawn - He coordinates with the National Park Service, which is in charge of the White House grounds, to determine who will be clearing away the picnic tables. (Brower 2015, pp. 257) He then sets about moving the tables. “I got the staff together and started sending them out to the south grounds—anybody I could think of—because I knew that we had to try to move as quickly as possible,” he will later recall. (National Journal 8/31/2002) However, at about 9:45 a.m., the White House is evacuated after the Secret Service learns of a possible threat against it (see (9:45 a.m.) September 11, 2001). (Associated Press 2001 pdf file; CNN 9/12/2001)
Staffers Continue Clearing the Grounds, despite the Danger - Around this time, Walters sees the smoke coming from the Pentagon, which was attacked at 9:37 a.m. (see 9:37 a.m. September 11, 2001), and realizes the White House could be hit next. And yet he decides that he needs to stay where he is in order to clear up the grounds. “As far as I was concerned, my responsibility was there at the White House,” he will comment. (Brower 2015, pp. 258) “I knew we had to get those tables out,” he will state, adding, “I even felt more urgency, since obviously this was a coordinated attack now.” (National Journal 8/31/2002) While the Secret Service is ordering people to run for their lives, Walters grabs a few of his colleagues and tells them they need to stay and help clear away the picnic tables. “I got the word that everybody was evacuating, but we had something that we needed to do,” he will comment. (Brower 2015, pp. 258) After hearing that another suspicious plane is approaching, however, Walters and his colleagues go to the southeast knoll, a rise in the White House lawn, and just stand there, watching the sky and waiting.
Lawn Is Cleared by Early Afternoon - By around 11:00 a.m., they are becoming impatient. Walters therefore says, “Guys, let’s go move some picnic tables.” The men then start carrying the picnic tables off the lawn. A police officer joins them and eventually about a dozen people are helping them to move the tables. By around 1:00 p.m. all of the tables have been removed from the lawn. At about 3:45 p.m., Walters is called by someone from the military, who asks him to clear the South Lawn so the president’s helicopter will be able to land there. Walters laughs and says this has already been done. (National Journal 8/31/2002) The president’s helicopter, with Bush on board, will land on the South Lawn at around 6:55 p.m. (see (6:54 p.m.) September 11, 2001). (CNN 9/12/2001; Rove 2010, pp. 263)
Usher Will Later Justify His Actions - Walters will, in 2016, explain why he made the effort to clear up the White House grounds, despite the danger to himself and his colleagues. “One of the things that I turned to in my own mind on 9/11 was the role that the White House plays in disasters, wars,” he will say, adding, “People have a tendency to turn to the White House.” He will continue: “And I knew that the president wasn’t gonna be satisfied talking from a bunker somewhere or away from the White House. And that’s why we put the effort that we did into cleaning up the south grounds, so that [his] helicopter could land there. That was what the American people were used to seeing—the presidential helicopter coming in—and the president was going to address the nation from the Oval Office.” (Peter Schnall 7/12/2016)

Laura Bush, the president’s wife, leaves the White House in her limousine, on her way to Capitol Hill where she is scheduled to testify before a Congressional committee, but she is unaware that a second plane has crashed into the World Trade Center. (Burleigh 10/15/2001; National Journal 8/31/2002; Bush 2010, pp. 198) Bush is set to appear before the Senate Committee on Health, Education, Labor, and Pensions, where she will talk about early childhood education. (McCaleb 9/12/2001; CNN 9/11/2002) She was informed of the first crash at the WTC by her lead Secret Service agent as she was getting into her limousine (see (8:55 a.m.) September 11, 2001).
First Lady Unaware of Second Crash - The limousine leaves the White House at 9:07 a.m., according to Noelia Rodriguez, the first lady’s press secretary. (National Journal 8/31/2002) The second aircraft, Flight 175, hit the WTC four minutes earlier (see 9:03 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 8) However, Bush and those with her in the limousine are unaware of this. (Bush 2010, pp. 197-198)
First Lady Thinks about Canceling Hearing - Nevertheless, Bush already thinks the Senate hearing she is on her way to should perhaps be canceled, because New York Senator Hillary Clinton is on the education committee and is therefore supposed to attend. Bush will comment, “Even after the first [crash], when I thought it was just an accident, I thought we probably should cancel, because Mrs. Clinton was on the committee and she’s from New York, and she’d probably want to rush home at that time.” (McQuillan 9/10/2001; Gerhart 2004, pp. 162) All the same, Bush continues with the two-mile journey from the White House to Capitol Hill. She will learn of the second crash, and realize this is a terrorist attack, shortly before arriving at the Russell Senate Office Building, where the hearing is set to take place (see (9:14 a.m.) September 11, 2001).
Secret Service Allows Bush to Head to Event - Members of Bush’s Secret Service detail apparently raise no objection to Bush going ahead with her trip to Capitol Hill. (CNN 9/11/2002; Gerhart 2004, pp. 162; Bush 2010, pp. 198) The Secret Service is responsible for protecting the first lady, and she is considered to be one of the nation’s “most visible targets.” (US Department of the Treasury 5/8/2001; Office of Management and Budget 7/2001, pp. 82 pdf file) The agency’s mission includes keeping her “in sight and out of harm’s way,” according to a book about the Secret Service by author Philip Melanson. (Melanson 2002, pp. 273) And, as one of the Secret Service’s “permanent protectees,” the first lady, like the president, has a detail of special agents assigned to her. (United States Secret Service 2002) Bush currently travels with four Secret Service agents and two Secret Service cars. (Kessler 2006, pp. 136; Kessler 2009, pp. 181) However, the Secret Service will only take her away from Capitol Hill to a “secure location”—actually the agency’s headquarters—after the terrorist attacks have ended (see (10:10 a.m.-10:55 a.m.) September 11, 2001). (Associated Press 9/11/2001; National Journal 8/31/2002; Kessler 2006, pp. 136)

NEADS commander Robert Marr.NEADS commander Robert Marr. [Source: Dick Blume]Numerous reports incorrectly claiming that aircraft have been hijacked are received while the terrorist attacks are taking place and into the afternoon. (Code One Magazine 1/2002; Baker 3/31/2005; Graff 9/9/2016) There are “multiple erroneous reports of hijacked aircraft” during the morning, according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 28) At around 9:09 a.m., the FAA Command Center reports that 11 aircraft are either not communicating with FAA facilities or flying unexpected routes. (Scott 6/3/2002) Major General Larry Arnold, the commander of the Continental United States NORAD Region, will later claim that during the “four-hour ordeal” of the attacks, a total of 21 planes are identified as possible hijackings. (Filson 2002; Code One Magazine 1/2002; Filson 2003, pp. 71) Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS), will say, “At one time I was told that across the nation there were some 29 different reports of hijackings.” (Baker 3/31/2005) Secret Service agent Dave Wilkinson, who travels with President Bush on Air Force One after it leaves Sarasota, Florida (see 9:54 a.m. September 11, 2001), will recall that by the time the plane reaches Offutt Air Force Base in Nebraska, at 2:50 p.m. (see 2:50 p.m. September 11, 2001), “there were like 15 to 20 planes still unaccounted for” nationwide. “For everything we knew, they were all hijacked,” he will say. (Graff 9/9/2016) Officials will claim that these false reports cause considerable confusion. Arnold will recall that particularly during the time between the Pentagon being hit at, 9:37 a.m., and Flight 93 going down, at around 10:03 a.m., “a number of aircraft are being called possibly hijacked.… There was a lot of confusion, as you can imagine.” (Filson 2003, pp. 71-73) He will say: “We were receiving many reports of hijacked aircraft. When we received those calls, we might not know from where the aircraft had departed. We also didn’t know the location of the airplane.” (Code One Magazine 1/2002) Marr will comment: “There were a number of false reports out there. What was valid? What was a guess? We just didn’t know.” (Filson 2003, pp. 73) Assistant Secretary of Defense for Public Affairs Victoria Clarke, who is in the Pentagon during the attacks and for most of the rest of the day, will recall: “There were lots of false signals out there. There were false hijack squawks, and a great part of the challenge was sorting through what was a legitimate threat and what wasn’t.” (CNN 6/17/2004; Clarke 2006, pp. 215-231)

The US Strategic Command (Stratcom) orders that its Global Guardian exercise be put on pause at this time, according to a 2006 article in The Bombardier, the newspaper for Barksdale Air Force Base, Louisiana. (Bombardier 9/8/2006 pdf file) Global Guardian is an annual exercise sponsored by Stratcom, which has its headquarters at Offutt Air Force Base, Nebraska. The exercise tests Stratcom’s ability to fight a nuclear war (see 8:30 a.m. September 11, 2001). (Dejka 2/27/2002; GlobalSecurity (.org) 4/27/2005) Many aircraft and personnel at Barksdale, as well as other military bases, are involved in it (see 8:48 a.m. September 11, 2001). (Villafuerte 9/8/2002) Global Guardian will be formally terminated at 10:44 a.m., according to The Bombardier (see (10:44 a.m.) September 11, 2001), although other reports will say it is canceled earlier on, possibly after the second World Trade Center tower is hit at 9:03 a.m. (Dejka 2/27/2002; Dejka 9/8/2002; Bombardier 9/8/2006 pdf file)

The jet fuel that spilled from Flight 175 when it hit the South Tower (see 9:03 a.m. September 11, 2001) has mostly burned up by this time. The National Institute of Standards and Technology (NIST), which later investigates the collapses, will say the “initial jet fuel fires themselves lasted at most a few minutes.” (National Institute of Standards and Technology 9/2005, pp. 183) Engineering professor Forman Williams will say the jet fuel “burned for maybe 10 minutes.” (Chertoff et al. 3/2005) Flight 175, a Boeing 767, had a capacity of 23,980 gallons, but was only carrying about 9,100 gallons of fuel when it hit the WTC. NIST will estimate that less than 1,500 gallons were consumed in a fireball inside the tower and 910 to 2,275 gallons were consumed in the fireballs outside the building. Approximately 6,100 gallons therefore splashed onto the office furnishings and started fires on various floors. However, after the jet fuel is used up, office fires burn until the building collapses. NIST will calculate that there were about four pounds per square foot of combustibles in the office space, or about 60 tons per floor. Offices in the WTC actually had fewer combustibles than other similar spaces due to the small number of interior walls and limited bookshelf space. NIST will later find that only three of sixteen perimeter columns it recovers reached a temperature of 250°C and neither of the two core columns it retrieves reached this temperature. NIST will also find that none of the samples it acquires reached a temperature above 600°C (see August 27, 2003). While steel does not melt until its temperature is about 1,600°C, it may begin to lose significant strength at over 500°C. (National Institute of Standards and Technology 9/2005, pp. 29, 38, 42, 77) The jet fuel also burned up in the North Tower about 10 minutes after it was hit (see 8:57 a.m. September 11, 2001). When a group of firefighters reach the bottom impact floor in the South Tower just before collapse, they only find two isolated fires (see 9:52 a.m. September 11, 2001).

Noelia Rodríguez.Noelia Rodríguez. [Source: Harvard University]Laura Bush, the president’s wife, is told that a second plane has crashed into the World Trade Center and realizes this is a terrorist attack while she is being driven from the White House to Capitol Hill, where she is scheduled to testify before a Congressional committee. (Burleigh 10/15/2001; CNN 9/11/2002; Bush 2010, pp. 197-198) Bush is set to appear before the Senate Committee on Health, Education, Labor, and Pensions at 10:00 a.m., where she will talk about early childhood education. (McQuillan 9/10/2001; McCaleb 9/12/2001; CNN 9/11/2002) Her lead Secret Service agent informed her of the first crash at the WTC as she was getting into her limousine, outside the White House, but she’d thought the crash was an accident (see (8:55 a.m.) September 11, 2001). (National Journal 8/31/2002; Gerhart 2004, pp. 162)
First Lady Told of Second Crash, Knows It Is Terrorism - The Secret Service agents traveling with Bush now tell the first lady about the second crash at the WTC while her limousine is driving up Pennsylvania Avenue, approaching Capitol Hill. “The car fell silent; we sat in mute disbelief,” Bush will later recall. “One plane might be a strange accident; two planes were clearly an attack.” She will note, “We knew then that it was terrorism.” (CNN 9/11/2002; Bush 2010, pp. 198)
Members of First Lady's Staff Learn of Crash - Members of Bush’s staff also learn about the second crash around this time, while they are on their way to Capitol Hill. Ashleigh Adams, the first lady’s deputy press secretary, learns of it while traveling in the press van. “It must have been only a couple of minutes after we departed the White House,” Adams will recall, “that the reporters’ and photographers’ pagers and cell phones started to go off, and someone shouted to me, ‘Ashleigh, the second Twin Tower was hit.’” Adams calls Noelia Rodriguez, the first lady’s press secretary, who is traveling in the staff van, and tells her the news. After Rodriguez arrives on Capitol Hill, she will jump out of the staff van, run to Bush’s limousine, and get inside. But she will find that the first lady has already been informed of the second crash. (National Journal 8/31/2002)
First Lady Learns of Crash 11 Minutes after It Occurs - Bush will recall that she arrives at the Russell Senate Office Building, where the hearing she is set to attend is supposed to take place, two minutes after she is told about the second crash, at 9:16 a.m., meaning she learns of the crash at 9:14 a.m. (Bush 2010, pp. 198) This is 11 minutes after the second plane, Flight 175, hit the WTC (see 9:03 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 8)

Frank Brogan.Frank Brogan. [Source: Publicity photo]The Secret Service allows President Bush to stay at the Emma E. Booker Elementary School in Sarasota, Florida, after a reading demonstration he was participating in has ended, even though he could be in danger at the school. (Martin 7/4/2004; Graff 9/9/2016) Bush has just left the classroom where the reading demonstration was held and entered a holding room next to it. There, he talks on the phone with officials in Washington, DC, and works on a statement to the nation that he wants to deliver before leaving the school (see (9:16 a.m.-9:29 a.m.) September 11, 2001). Members of his staff in the holding room apparently have little information about the terrorist attacks beyond what has been reported on television. They are in contact with the White House Situation Room but not the Pentagon and, according to the 9/11 Commission Report, “No one in the traveling party had any information during this time that other aircraft were hijacked or missing.” (Sammon 10/7/2002; 9/11 Commission 7/24/2004, pp. 38-39) All the same, Secret Service agents and other personnel with the president are concerned that Bush could be in danger at the school, and some of them are worried that terrorists might attack the place (see (9:04 a.m.-9:33 a.m.) September 11, 2001). (Morell 9/2006 pdf file; Graff 9/9/2016)
Bush's Lead Agent Wants to Evacuate the President - Edward Marinzel, the head of Bush’s Secret Service detail, is “eager to get the president out of the school, to Air Force One, and airborne,” according to Karl Rove, Bush’s senior adviser. (Rove 2010, pp. 251) He therefore approaches Bush and tells him, “We need to get you to Air Force One and get you airborne.” (Graff 9/9/2016) However, his concern does not result in Bush being evacuated from the school right away. The Secret Service will later tell the 9/11 Commission that although its agents “were anxious to move the president to a safer location” while he was in the holding room, they “did not think it imperative for him to run out the door.” (9/11 Commission 7/24/2004, pp. 39)
Chief of Staff Wants Bush to Give His Speech before Leaving - Andrew Card, Bush’s chief of staff, suggests that Bush should be allowed to give his speech to the nation from the school before leaving. He says that “we have a whole auditorium full, waiting for the next event”—meaning Bush’s speech—and there is “no imminent threat there in Sarasota,” according to Dave Wilkinson, assistant special agent in charge of the presidential protection division. The Secret Service therefore accepts a compromise and agrees that Bush can give his speech before leaving. (Graff 9/9/2016)
Bush Should Be Taken to the 'Closest Secure Location' - Author Philip Melanson, an expert on the Secret Service, will criticize Bush’s Secret Service detail for failing to get the president away from the school immediately after the second hijacked plane crashed into the World Trade Center, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “With an unfolding terrorist attack, the procedure should have been to get the president to the closest secure location as quickly as possible, which clearly is not a school,” he will state. (Martin 7/4/2004) Bush himself will comment on the situation while he is in the holding room, saying, “One thing for certain: I needed to get out of where I was.” (Sammon 2002, pp. 93)
Bush Refuses to Leave - And yet the president refuses to leave the school at this time when he is urged to do so, according to Frank Brogan, lieutenant governor of Florida, who is in the holding room with him. “The Secret Service tried to get the president to return to Air Force One immediately,” Brogan will state, “but he refused, saying he was committed to staying on the ground long enough to write a statement about what was happening, read it to the nation, and lead a moment of silence for the victims.” (Frost 9/18/2003) Bush “was courageously insistent about remaining on the ground to make a statement to the people of America,” Brogan will comment. (Stein 9/11/2011) Bush will give his speech to the nation, which will be broadcast live on television, from the school library at 9:30 a.m. (see 9:30 a.m. September 11, 2001). (White House 9/11/2001; Bohn 2015, pp. 215) He will finally leave the school at around 9:35 a.m. (see (9:34 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 39)

Brian Wilson.Brian Wilson. [Source: Publicity photo]There is apparently no increase in the level of security at the Capitol building in Washington, DC, even though First Lady Laura Bush has arrived at the nearby Russell Senate Office Building and more than 10 minutes have passed since a second plane hit the World Trade Center. (Gilbert et al. 2002, pp. 64; 9/11 Commission 7/24/2004, pp. 8; Bush 2010, pp. 198) At 9:16 a.m., Bush arrived at the Russell Senate Office Building, located just north of the Capitol building, where she was scheduled to testify before a Senate committee at 10:00 a.m. (McQuillan 9/10/2001; McCaleb 9/12/2001; Bush 2010, pp. 198)
Reporter Sees No Signs of Increased Security - The first lady is considered one of the nation’s “most visible targets,” and, as one of the Secret Service’s “permanent protectees,” like the president, she has a detail of special agents assigned to her. (US Department of the Treasury 5/8/2001; Office of Management and Budget 7/2001, pp. 82 pdf file; United States Secret Service 2002) And yet, even though Bush has arrived on Capitol Hill, and over 10 minutes have passed since the second aircraft hit the WTC (see 9:03 a.m. September 11, 2001), there is apparently no increase in the level of security at the Capitol building. Fox News correspondent Brian Wilson will later recall that when reporting from the Capitol building around this time, he is “talking about the first lady being in the Capitol and saying that I had not seen any signs of tighter security in the building.”
Reporter Surprised at Plan to Hold a Photo Op - Wilson is also surprised that, although the Senate hearing Bush was scheduled to attend has been canceled, the first lady is still going to make a public appearance. He will comment that “they were (incredibly) trying to set up a brief photo opportunity.” (Gilbert et al. 2002, pp. 64; 9/11 Commission 7/24/2004, pp. 8) (Wilson is presumably referring to Laura Bush’s appearance before reporters and cameras alongside Senators Edward Kennedy (D-MA) and Judd Gregg (R-NH), which takes place at 9:41 a.m. (see 9:41 a.m. September 11, 2001). (Associated Press 9/11/2001; CNN 9/11/2001; Bush 2010, pp. 199) )
Capitol Evacuated Later On - The Capitol building will only be evacuated at 9:48 a.m., apparently in response to reports of a plane heading toward it (see 9:48 a.m. September 11, 2001). (Associated Press 9/11/2001; Associated Press 8/21/2002; CNN 9/11/2006) The first lady will only be taken away from the Russell Office Building to a “secure location” by members of the Secret Service at 10:10 a.m. (see (10:10 a.m.-10:55 a.m.) September 11, 2001). (Associated Press 9/11/2001; National Journal 8/31/2002; Bush 2010, pp. 200)

A meeting is held in the office of Carl Truscott, the Secret Service special agent in charge of the presidential protective division (PPD), during which Truscott and three other senior Secret Service agents discuss security enhancements at the White House. Truscott, who is responsible for the overall security of the White House, will later say that he contacted the three other agents after watching “the CNN broadcast of the aircraft crashing into the World Trade Center,” and asked them to come to his office in the Eisenhower Executive Office Building, next to the White House (see (After 8:48 a.m.) September 11, 2001). The names of these agents are unstated, but they are a deputy special agent in charge of the PPD, an assistant to the special agent in charge of the PPD, and an assistant division chief of the Secret Service’s technical security division. Their meeting begins at “approximately 9:18 a.m.,” according to Truscott. (United States Secret Service 10/1/2001)
Agents Discuss Measures to Increase Security - Truscott and the other agents briefly discuss the Secret Service assets that have so far been deployed in response to the crisis. (United States Secret Service 9/12/2001) Issues that are addressed during the meeting, according to Truscott, include placing counter-sniper support on the White House; placing counter-surveillance units near the White House; opening the Emergency Operations Center; increasing the number of emergency response teams; increasing technical security division support; providing counter-assault team support to First Lady Laura Bush’s Secret Service detail at the US Capitol building; providing protection for National Security Adviser Condoleezza Rice; and alerting the Army Corps of Engineers structural collapse team.
Agent Learns of Aircraft Approaching Washington - While the meeting is taking place, Truscott receives a call from Danny Spriggs, an agent at the Secret Service’s headquarters in Washington, DC, informing him that a suspicious aircraft is flying toward the capital (see (Shortly After 9:35 a.m.) September 11, 2001). And while he is on the phone with Spriggs, Truscott receives a call from a “White House security representative.” During that call, Truscott instructs the security representative to evacuate the White House. (United States Secret Service 10/1/2001) (The White House will begin evacuating at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). (Associated Press 2001 pdf file; CNN 9/12/2001) )
Agent Suggests Going to White House Bunker - At some point, Truscott suggests that those at the meeting go to the Presidential Emergency Operations Center (PEOC), a bunker below the White House. Truscott will subsequently head to the PEOC. Apparently at least one other person at the meeting—the assistant division chief of the technical security division—will head there with him. (United States Secret Service 9/12/2001) On his way to the PEOC, Truscott will meet Rice in the White House Situation Room and accompany her down to the PEOC (see (9:45 a.m.) September 11, 2001). (United States Secret Service 10/1/2001) Presumably as a result of the meeting in Truscott’s office, the Secret Service will implement “a number of security enhancements around the White House complex,” according to the 9/11 Commission Report (see (After 9:18 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 35-36)

Members of the Secret Service’s uniformed division.Members of the Secret Service’s uniformed division. [Source: Joe Marquette / Associated Press]The Secret Service begins implementing a number of security enhancements around the White House complex. (9/11 Commission 7/24/2004, pp. 35-36) The measures are apparently being implemented on the orders of a number of senior Secret Service agents who have been meeting in the office of Carl Truscott, the special agent in charge of the presidential protective division, who is responsible for the overall security of the White House (see (9:18 a.m.) September 11, 2001). During that meeting, according to Truscott, the agents have discussed “security enhancements at the White House,” such as “placing counter-sniper support on the White House” and “placing counter-surveillance units near the White House.” (United States Secret Service 10/1/2001) The officials who ordered the security enhancements “did not know that there were additional hijacked aircraft or that one such aircraft was en route to Washington,” according to the 9/11 Commission Report. The measures are simply “precautionary steps taken because of the strikes in New York.” (9/11 Commission 7/24/2004, pp. 36) However, once the Secret Service has established a perimeter around the White House, its uniformed division officers are ordered “to stow their submachine guns out of sight,” according to US News and World Report, because officials fear that they look too “militaristic.” The uniformed division officers are furious about this. “All we were left with were our pistols,” one of them will later complain. (Ragavan 12/1/2002) The security enhancements are initiated after 9:03 a.m., when the second plane hit the World Trade Center, according to the 9/11 Commission Report (see 9:03 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 35-36) However, the meeting of senior Secret Service agents during which the measures were discussed began at around 9:18 a.m., according to Truscott, which would indicate that the measures are initiated some time after 9:18 a.m. (United States Secret Service 10/1/2001) Furthermore, the Secret Service will only order that the White House be evacuated at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). (Associated Press 2001 pdf file; CNN 9/12/2001)

According to the 9/11 Commission, NEADS is contacted by the FAA’s Boston Center. Colin Scoggins, Boston Center’s military liaison, tells it: “I just had a report that American 11 is still in the air, and it’s on its way towards—heading towards Washington.… That was another—it was evidently another aircraft that hit the tower. That’s the latest report we have.… I’m going to try to confirm an ID for you, but I would assume he’s somewhere over, uh, either New Jersey or somewhere further south.” The NEADS official asks: “He—American 11 is a hijack?… And he’s heading into Washington?” Scoggins answers yes both times and adds, “This could be a third aircraft.” Somehow Boston Center has been told by FAA headquarters that Flight 11 is still airborne, but the 9/11 Commission will say it hasn’t been able to find where this mistaken information came from.
Scoggins Makes Error - Vanity Fair magazine will later add, “In Boston, it is Colin Scoggins who has made the mistaken call.” Scoggins will explain why he believes he made this error: “With American Airlines, we could never confirm if [Flight 11] was down or not, so that left doubt in our minds.” He says he was monitoring a conference call between FAA centers (see 8:28 a.m. September 11, 2001), “when the word came across—from whom or where isn’t clear—that American 11 was thought to be headed for Washington.” However, Boston Center was never tracking Flight 11 on radar after losing sight of it near Manhattan: “The plane’s course, had it continued south past New York in the direction it was flying before it dipped below radar coverage, would have had it headed on a straight course toward DC. This was all controllers were going on.” Scoggins says, “After talking to a supervisor, I made the call and said [American 11] is still in the air.” (Northeast Air Defense Sector 9/11/2001; 9/11 Commission 6/17/2004; Bronner 8/1/2006)
Myers Refers to Mistaken Report - In the hours following the attacks, acting Chairman of the Joint Chiefs of Staff Richard Myers will apparently refer to this erroneous report that Flight 11 is still airborne and heading toward Washington, telling the Associated Press that “prior to the crash into the Pentagon, military officials had been notified that another hijacked plane had been heading from the New York area to Washington.” Myers will say “he assumed that hijacked plane was the one that hit the Pentagon, though he couldn’t be sure.” (Fournier 9/11/2001)

Rich Miles, the manager of United Airlines’ System Operations Control center, located outside Chicago, issues an advisory to all United Airlines facilities, including the flight dispatchers. This advisory, which is issued under the name of UAL Chief Operating Officer Andy Studdert, states that Flight 175 has been involved in an accident in New York City, and that the airline’s crisis center has been activated. (Mccartney and Carey 10/15/2001; 9/11 Commission 8/26/2004, pp. 26) This appears to be United Airlines’ first proper confirmation that Flight 175 has crashed. However, it will not issue a press release confirming the crash until 11:53 a.m. (see 11:53 a.m. September 11, 2001). (United Airlines 9/11/2001)

Alan Scott.Alan Scott. [Source: United States Air Force]NORAD’s Northeast Air Defense Sector (NEADS) processes and transmits an order to Langley Air Force Base in Virginia, to scramble three of its F-16 fighter jets. (North American Aerospace Defense Command 9/18/2001; Tyson 4/16/2002; 9/11 Commission 8/26/2004, pp. 16) NEADS mission crew commander Major Kevin Nasypany instructed his personnel to issue this order one minute earlier (see 9:23 a.m. September 11, 2001). Although he’d originally wanted the Langley jets sent to the Washington area, he will soon adjust this heading to send them to the Baltimore area. (9/11 Commission 7/24/2004, pp. 27)
NEADS Orders Jets North - A NEADS officer calls Langley Air Force Base and instructs: “Langley command post, this is Huntress with an active air defense scramble for Quit 2-5 and Quit 2-6.… Scramble immediately.… Scramble on a heading of 010, flight level 290.” This means the jets are to head in a direction just east of north, at an altitude of 29,000 feet. (9/11 Commission 1/9/2004; 9/11 Commission 8/26/2004, pp. 96; Spencer 2008, pp. 142) At Langley Air Force Base, a Klaxon horn will sound, notifying the pilots of the scramble order (see 9:24 a.m. September 11, 2001), and they will be airborne by 9:30 (see (9:25 a.m.-9:30 a.m.) September 11, 2001). (Filson 2003, pp. 63; 9/11 Commission 8/26/2004, pp. 16; Spencer 2008, pp. 141)
Fighters Launched in Response to Flight 77? - In later testimony, military officials will give contradictory explanations for why the Langley F-16s are scrambled. An early NORAD timeline will indicate the fighters are launched in response to NORAD being notified at 9:24 that Flight 77 has been hijacked (see (9:24 a.m.) September 11, 2001). (North American Aerospace Defense Command 9/18/2001) Colonel Alan Scott, the former vice commander of the Continental US NORAD Region (CONR), will suggest the same, telling the 9/11 Commission: “At 9:24 the FAA reports a possible hijack of [Flight] 77.… And at that moment as well is when the Langley F-16s were scrambled out of Langley.” (9/11 Commission 5/23/2003; 1st Air Force 8/8/2006) And a timeline provided by senior Defense Department officials to CNN will state, “NORAD orders jets scrambled from Langley” in order to “head to intercept” Flight 77. (CNN 9/17/2001)
In Response to Flight 93? - However, Major General Larry Arnold, the CONR commander, will give a different explanation. He will tell the 9/11 Commission, “we launched the aircraft out of Langley to put them over top of Washington, DC, not in response to American Airline 77, but really to put them in position in case United 93 were to head that way.” (9/11 Commission 5/23/2003)
In Response to Incorrect Report about Flight 11? - In 2004, the 9/11 Commission will dispute both these previous explanations, and conclude that the Langley jets are scrambled in response to an incorrect report that Flight 11 is still airborne and heading toward Washington, DC (see 9:21 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 26-27; 9/11 Commission 8/26/2004, pp. 15) Tape recordings of the NEADS operations floor will corroborate this account. (Bronner 8/1/2006) According to the 9/11 Commission, its conclusion is also confirmed by “taped conversations at FAA centers; contemporaneous logs compiled at NEADS, Continental Region headquarters, and NORAD; and other records.” (9/11 Commission 7/24/2004, pp. 34) Major Nasypany will tell the Commission that the reason the Langley jets are directed toward the Baltimore area is to position them between the reportedly southbound Flight 11 and Washington, as a “barrier cap.” (9/11 Commission 7/24/2004, pp. 27 and 461) John Farmer, senior counsel to the 9/11 Commission, will later suggest that NORAD deliberately misled Congress and the Commission by hiding the fact that the Langley scramble takes place in response to the erroneous report that Flight 11 is still airborne. He will write that the mistaken report “appears in more logs, and on more tapes, than any other single event that morning.… It was the reason for the Langley scramble; it had triggered the Air Threat Conference Call. Yet it had never been disclosed; it was, instead, talked around.” (Farmer 2009, pp. 266-267)
Conflicting Times - Early news reports will put the time of the scramble order slightly later than the 9/11 Commission places it, between 9:25 and “about 9:27.” (Washington Post 9/12/2001; CNN 9/17/2001; CNN 9/19/2001) But a NORAD timeline released a week after the attacks will give the same time as the Commission does, of 9:24. (North American Aerospace Defense Command 9/18/2001; 9/11 Commission 7/24/2004, pp. 27)

Captain Craig Borgstrom.Captain Craig Borgstrom. [Source: US Air Force / Austin Knox]The three F-16 fighter jets ordered to scramble from Langley Air Force Base in Virginia (see 9:24 a.m. September 11, 2001) take off and, radar data will show, are airborne by 9:30 a.m. (North American Aerospace Defense Command 9/18/2001; Tyson 4/16/2002; 9/11 Commission 7/24/2004, pp. 27)
Delayed during Launch - Major Dean Eckmann will recall that, after receiving the scramble order, he and the two other pilots have “a pretty quick response time. I believe it was four to five minutes we were airborne from that point.” (BBC 9/1/2002) According to the 1st Air Force’s book about 9/11, the three fighters are “given highest priority over all other air traffic at Langley Air Force Base” as they are launching. (Filson 2003, pp. 63) But, according to author Lynn Spencer, in spite of this, the jets are delayed. As Eckmann is approaching the runway, he calls the control tower for clearance to take off, but the tower controller tells him, “Hold for an air traffic delay.” Air traffic controllers at the FAA’s Washington Center “have not had time to clear airliners out of the way for the northerly heading. Dozens of aircraft at various altitudes fill the jets’ route.” After having to wait two minutes, Eckmann complains: “We’re an active air scramble. We need to go now!” Finally, the tower controller tells him, “Roger, Quit flight is cleared for takeoff, 090 for 60,” meaning the fighters are to fly due east for 60 miles (see (9:30 a.m.) September 11, 2001).
Taking Off - The three jets launch 15 seconds apart, with Eckmann in front and the two other jets following. (Spencer 2008, pp. 143-144) Pilot Craig Borgstrom will later recall, “[W]e took off, the three of us, and basically the formation we always brief on alert, we’ll stay in a two- to three-mile trail from the guy in front.” (Filson 2003, pp. 63) According to the BBC, the pilots get a signal over their planes’ transponders, indicating an emergency wartime situation. (BBC 9/1/2002)
Could Reach Washington before Pentagon Attack - F-16s have a maximum speed of 1,500 mph at high altitude, or 915 mph at sea level, so the three fighters could plausibly travel the 130 miles from Langley Air Force Base to Washington in just minutes. (Chant 1987, pp. 404; Associated Press 6/16/2000; Weisman 9/16/2001; Graham 9/16/2001 pdf file; US Air Force 10/2007) Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will tell the 9/11 Commission, “I think if those aircraft had gotten airborne immediately, if we were operating under something other than peacetime rules, where they could have turned immediately toward Washington, DC, and gone into burner, it is physically possible that they could have gotten over Washington” before 9:37, when the Pentagon is hit. (9/11 Commission 5/23/2003) Yet according to the 9/11 Commission, the jets are redirected east over the Atlantic Ocean and will be 150 miles from the Pentagon when it is hit (see 9:30 a.m.-9:37 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 27)
Conflicting Times - Some early news reports after 9/11 will say the Langley jets take off at the later time of 9:35 a.m. (Washington Post 9/12/2001; CNN 9/14/2001; Graham 9/15/2001; CNN 9/17/2001) But according to Colonel Alan Scott, the former vice commander of the Continental US NORAD Region, though the jets are airborne at 9:30, the report of this does not come down until 9:35, so this fact may account for the conflicting times. (9/11 Commission 5/23/2003)

The FAA’s Boston Center contacts NORAD’s Northeast Air Defense Sector (NEADS) and reports that another aircraft, Delta Air Lines Flight 1989, is missing. (9/11 Commission 5/23/2003; 9/11 Commission 6/17/2003; 9/11 Commission 2004) Why the Boston Center does this is unclear, since Delta 1989 is currently being handled by the FAA’s Cleveland Center, not the Boston Center. (Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 7/24/2004, pp. 10) And, according to the 9/11 Commission, Delta 1989 “never turned off its transponder,” so it should still be clearly visible on radar. (9/11 Commission 7/24/2004, pp. 16, 28) Twelve minutes later, at 9:39, Boston Center will call NEADS and incorrectly tell it that Delta 1989 is a possible hijack (see 9:39 a.m. September 11, 2001). (9/11 Commission 2004; Bronner 8/1/2006)

A Delta Air Lines Boeing 767, the same kind of aircraft as Delta 1989.A Delta Air Lines Boeing 767, the same kind of aircraft as Delta 1989. [Source: Public domain]The FAA’s Cleveland Center incorrectly concludes that Delta Air Lines Flight 1989 has been hijacked, but accounts will conflict over how it comes to this conclusion. (Adams, Levin, and Morrison 8/13/2002; Spencer 2008, pp. 167) Delta 1989, a Boeing 767, is currently in the sector of airspace being monitored by Cleveland Center air traffic controller John Werth. (9/11 Commission 10/2/2003 pdf file; Levin 9/11/2008) It is flying west over Pennsylvania, approaching the Ohio border, and is about 25 miles behind Flight 93. FBI agents suspected Delta 1989 might be the next plane to be hijacked and called the Cleveland Center after the second attack on the World Trade Center, with the warning to watch this flight (see Shortly After 9:03 a.m. September 11, 2001). (Adams, Levin, and Morrison 8/13/2002) A supervisor at the center told Werth to keep an eye on the flight because, as Werth will later recall, “he was a suspected hijacking because he had taken off from Boston at approximately the same time as” the first two hijacked aircraft, Flights 11 and 175. (9/11 Commission 10/1/2003 pdf file; Levin 9/11/2008)
Controllers Hear Suspicious Communications - When, at 9:28, Werth hears the sound of screaming (subsequently determined to have come from Flight 93) over the radio (see (9:28 a.m.) September 11, 2001), he is unsure which of seven or eight possible aircraft it is coming from. The radio frequency is put on the speaker so other controllers can hear it, and they subsequently make out the words, “get out of here.” (9/11 Commission 10/1/2003 pdf file; 9/11 Commission 7/24/2004, pp. 11, 28)
Controllers Think Delta 1989 Is Hijacked - According to USA Today, when Cleveland Center controllers then hear a voice with a heavy accent over the radio, saying “Ladies and gentlemen: Here the captain.… We have a bomb on board” (see (9:32 a.m.) September 11, 2001), they mistakenly think it is coming from Delta 1989, not Flight 93. They suspect the flight has been hijacked, and start informing their chain of command. “Officials at Cleveland Center rush word to Washington: Hijackers have another flight. At the Federal Aviation Administration’s Command Center in Herndon, Virginia, Delta Flight 1989 joins a growing list of suspicious jets.” (Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 7/24/2004, pp. 12)
Werth Decides Hijacked Aircraft Is Flight 93 - Werth then calls all of the aircraft in his sector, and Flight 93 is the only one that does not respond. He also sees Flight 93 go into a quick descent and then come back up again. Werth therefore concludes that it is Flight 93, not Delta 1989, that has been hijacked, and instructs his supervisor to “tell Washington” of this. (9/11 Commission 10/1/2003 pdf file; 9/11 Commission 10/2/2003 pdf file) However, events in the following minutes will cause Cleveland Center controllers to remain suspicious of Delta 1989 (see (Shortly After 9:44 a.m.) September 11, 2001 and 9:45 a.m. September 11, 2001). (Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 10/2/2003 pdf file; Spencer 2008, pp. 168; Levin 9/11/2008)
Book Gives Alternative Account - In a book published in 2008, author Lynn Spencer will give a different explanation for why Cleveland Center becomes suspicious of Delta 1989. According to her account, after hearing a later radio transmission where a hijacker again says “There is a bomb on board” (see (9:39 a.m.) September 11, 2001), Werth begins to hand off his flights to other controllers so he can devote his full attention to Flight 93. “In the distraction of the emergency, the crew of Delta 1989 misses the hand-off to the new frequency. The new sector controller for Delta 1989 calls out to the plane several times and gets no response.” As a result, “News travels fast,” and “Soon, word on the FAA’s open teleconference call is that a fifth aircraft is out of radio contact: Delta 1989… is added to the list of suspect aircraft.” (Spencer 2008, pp. 167) At 9:39 a.m., even though it is not responsible for handling Delta 1989, the FAA’s Boston Center will call NORAD’s Northeast Air Defense Sector (NEADS) and incorrectly tell it that Delta 1989 is another possible hijack (see 9:39 a.m. September 11, 2001). (9/11 Commission 2004; Bronner 8/1/2006)

The National Miilitary Command Center, inside the Pentagon.The National Miilitary Command Center, inside the Pentagon. [Source: US Department of Defense]The National Military Command Center (NMCC) at the Pentagon finally commences and runs a “significant event conference” in response to the ongoing crisis, 26 minutes after the second plane hit the World Trade Center and officers in the NMCC realized the US was under terrorist attack. (9/11 Commission 6/17/2004 pdf file; 9/11 Commission 7/24/2004, pp. 37; Garamone 9/7/2006)
NMCC Directors Decided to Establish Conference - After those in the NMCC saw Flight 175 hitting the WTC live on television at 9:03 a.m. (see 9:03 a.m. September 11, 2001), Captain Charles Leidig, the acting deputy director for operations (DDO) in the center throughout the attacks, and Commander Pat Gardner, the assistant DDO, talked about the need to convene a significant event conference so there could be a discussion of what actions were to be taken in response. The DDO and the assistant DDO are the two officers responsible for deciding what type of conference the NMCC should convene, and when it should do so. Because there is no specific procedure for dealing with terrorist attacks, Leidig and Gardner decided a significant event conference would most suit their needs, because it would have the flexibility of allowing more people to be added in as required. They also discussed who would need to be on this conference. (9/11 Commission 4/29/2004 pdf file) But Major Charles Chambers, who is currently on duty in the NMCC, will give a slightly different account. According to Chambers, Staff Sergeant Val Harrison had a phone in her hand and said NORAD was asking for a significant event conference. Leidig had agreed, and so Harrison started establishing the conference.
Conference Begins with Recap of Situation - According to Chambers, “The computer does a mass dialing to connect to those command centers that are always included” in an NMCC conference call, but Harrison also had to manually call the civilian agencies that were going to be included in the conference, such as the FAA, the FBI, and the Federal Emergency Management Agency (FEMA). (US Department of Defense 9/2001) The conference then begins at 9:29 a.m. with a brief recap: Two aircraft have hit the WTC, there is a confirmed hijacking of Flight 11, and fighter jets have been scrambled from Otis Air National Guard Base in Massachusetts (see 8:46 a.m. September 11, 2001). The FAA is asked to provide an update, but its line is silent as the agency has not yet been added to the call (see (9:29 a.m.-12:00 p.m.) September 11, 2001). A minute later, Leidig states that it has just been confirmed that Flight 11 is still airborne and is heading toward Washington, DC. (This incorrect information apparently arose minutes earlier during a conference call between FAA centers (see 9:21 a.m. September 11, 2001).) (9/11 Commission 7/24/2004, pp. 37) NMCC conference calls are moderated by the DDO. (9/11 Commission 7/21/2003 pdf file) Leidig will tell the 9/11 Commission that they are conducted over “a special phone circuit, and it’s classified to be able to pass information, relay information between very senior leadership all the way over to the White House.” (9/11 Commission 6/17/2004)
NMCC Struggled to Convene Conference - Some officers currently on duty in the NMCC will later complain about circumstances that delayed the establishing of the significant event conference. Chambers will recall that the conference took “much longer than expected to bring up.” (US Department of Defense 9/2001) Gardner will tell the 9/11 Commission that the NMCC had been “struggling to build the conference,” which “didn’t get off as quickly as hoped.” (9/11 Commission 5/5/2004) He will describe his “frustration that it wasn’t brought up more quickly.” (9/11 Commission 5/12/2004)
Other Conference and Connection Problems Delayed Call - Preparations for the conference were disrupted as a result of the CIA convening a National Operations and Intelligence Watch Officer Network (NOIWON) conference call between government agencies in the Washington area, reportedly at sometime between 9:16 a.m. and 9:25 a.m. (see (Between 9:16 a.m. and 9:25 a.m.) September 11, 2001). According to a 9/11 Commission memorandum, the NMCC had “abandoned its attempt to convene a [significant event conference] so its watch officers could participate in the NOIWON conference.” (Federal Aviation Administration 9/11/2001; Federal Aviation Administration 9/11/2001; 9/11 Commission 7/21/2003 pdf file) Another factor that slowed attempts to convene the significant event conference was a problem with connecting some agencies to it. According to Chambers, “A couple of the civil agencies couldn’t be reached and others kept dropping off moments after connecting.” He will recall, “We finally decided to proceed without those agencies that were having phone problems.” (US Department of Defense 9/2001) Leidig had announced that the NMCC would have to start without those agencies and add them to the conference later on. (9/11 Commission 5/12/2004)
Call Ends after Five Minutes - The significant event conference ends after only a few minutes, following a recommendation by NORAD that it be reconvened as an “air threat conference.” It is brought to an end at around 9:34 a.m., and will resume as an air threat conference at 9:37 a.m. (see 9:37 a.m.-9:39 a.m. September 11, 2001).

Thomas Von Essen.Thomas Von Essen. [Source: Publicity photo]The Office of Emergency Management’s Emergency Operations Center (EOC) in World Trade Center Building 7 is evacuated in response to a report that more commercial planes are unaccounted for. (9/11 Commission 7/24/2004, pp. 305) The EOC, which opened in 1999 (see June 8, 1999), is a state-of-the-art facility on the 23rd floor of WTC 7 that is intended to serve as a meeting place for city leaders in the event of an act of terrorism or other kind of crisis. (CNN 6/7/1999; City of New York 2/18/2001) Office of Emergency Management (OEM) officials activated it shortly after Flight 11 crashed into the North Tower of the WTC (see (Shortly After 8:46 a.m.) September 11, 2001). (Bylicki 6/19/2003; 9/11 Commission 7/24/2004, pp. 293)
Staffers Discussed Evacuation after the First Crash - Soon after the crash occurred, officials in the EOC “began discussing with OEM staff whether or not they should evacuate the building,” according to a report by Tricia Wachtendorf of the Disaster Research Center at the University of Delaware. (Wachtendorf 2004, pp. 77) Richard Rotanz, deputy director of the OEM, and some other officials in the EOC conducted a “threat analysis” after the second hijacked plane crashed into the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). (Rotanz 1/2002)
Staffers Want to Stay in the Operations Center - Personnel are reluctant to leave the EOC because in it they have “a tremendous amount of resources at their fingertips” and they are “best able to handle an emergency of this scale,” Wachtendorf will later write. Furthermore, there is no clear procedure to move to or establish an alternative operations center if it is abandoned. “I couldn’t think of where we would go if we left the EOC because at that time we didn’t have a backup facility,” one official will recall. There is, in fact, “no formalized evacuation plan for the EOC,” according to Wachtendorf. (Wachtendorf 2004, pp. 77-79)
OEM Deputy Director Orders the Evacuation - However, Richard Bylicki, a police sergeant assigned to the OEM, was told during a call with the FAA that at least one other plane, in addition to the two that hit the Twin Towers, is unaccounted for and possibly heading for New York (see (9:30 a.m.) September 11, 2001), and he passed this information on to Rotanz. (Bylicki 6/19/2003) Rotanz was given the same warning by a Secret Service agent who works in WTC 7. (Rotanz 1/2002; 9/11 Commission 7/24/2004, pp. 305) Based on this information, he “surmised that [WTC 7] was potentially the next target,” Bylicki will recall. He consequently now orders all OEM employees to leave the building. (Bylicki 6/19/2003; 9/11 Commission 4/7/2004) A Secret Service agent, presumably the one who told Rotanz about the additional unaccounted-for planes, also reportedly advises EOC personnel to evacuate. He says, “There’s a reported third plane headed toward the East Coast and we’re warning everybody to vacate the building,” Fire Department Captain Abdo Nahmod will recall. (Journal of Emergency Medical Services 9/2011, pp. 42 pdf file)
Some Liaisons Have Come to the Operations Center - Various city agencies were contacted after the EOC was activated and instructed to send their designated representatives to the center. None of these representatives have arrived by the time the EOC is evacuated, according to the 9/11 Commission Report. (9/11 Commission 5/18/2004 pdf file; 9/11 Commission 7/24/2004, pp. 293, 305) However, contradicting this claim, a number of emergency responders will recall arriving at the EOC before it is evacuated, to serve as representatives for their agencies. (Nahmod 10/11/2001; Zarrillo 10/25/2001; Yakimovich 12/4/2001; Journal of Emergency Medical Services 9/2011, pp. 42 pdf file)
Staffers Are Initially Slow to Leave - Personnel reportedly do not initially respond to the evacuation order with a sense of urgency. They “calmly collected personal belongings and began removing OEM records,” a report by the Mineta Transportation Institute will state. But they are subsequently “urged to abandon everything and leave the building quickly.” (Jenkins and Edwards-Winslow 9/2003, pp. 16 pdf file) After evacuating from the EOC, they assemble in the lobby of WTC 7 and await further instructions over radio. (Bylicki 6/19/2003) Most of them think they are only temporarily abandoning their facility and expect to return to it later in the day. They do not anticipate WTC 7 being affected by fires (see 4:10 p.m. September 11, 2001) and then collapsing late this afternoon (see (5:20 p.m.) September 11, 2001). (Wachtendorf 2004, pp. 84)
Fire Commissioner Will Be Surprised That the Center Is Evacuated - Fire Commissioner Thomas Von Essen will be surprised when he finds that the EOC has been evacuated, since the center was designed for dealing with a crisis like the one currently taking place. “I thought that was where we should all be because that’s what [it] was built for,” he will comment. He will arrive at WTC 7 looking for Mayor Rudolph Giuliani shortly before 9:59 a.m., when the South Tower collapses (see 9:59 a.m. September 11, 2001). When he learns that the EOC has been evacuated, he will think: “How ridiculous. We’ve got a 13-million-dollar command center and we can’t even use it.” He will say in frustration: “How can we be evacuating OEM? We really need it now.” (Essen 2002, pp. 26; Fink and Mathias 2002, pp. 230)
Time of the Evacuation Is Unclear - It is unclear exactly when the EOC is evacuated. The order to evacuate is issued at “approximately 9:30” a.m., according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 305) But, according to a report by the National Institute of Standards of Technology, the evacuation occurs slightly later than this, at “approximately 9:44 a.m.” (National Institute of Standards and Technology 9/2005, pp. 109) Other accounts will suggest it may even have taken place before the second attack on the WTC occurred (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001). (Barrett and Collins 2006, pp. 34; Dylan Avery 2007) Many people in the rest of WTC 7 left the building earlier on, around the time of the second attack (see (9:03 a.m.) September 11, 2001). (9/11 Commission 5/18/2004 pdf file; National Institute of Standards and Technology 9/2005, pp. 109)

The OEM command bus.The OEM command bus. [Source: New York City Office of Emergency Management]Personnel from New York’s Office of Emergency Management (OEM) use the OEM command bus as their command post after their command center in World Trade Center Building 7 has been evacuated. (Jenkins and Edwards-Winslow 9/2003, pp. 20 pdf file; 9/11 Commission 4/7/2004) The OEM command center, on the 23rd floor of WTC 7, is intended to coordinate the city’s response to emergencies, including terrorist attacks. (Miller 6/8/1999) However, it was evacuated at around 9:30 a.m., according to the 9/11 Commission Report, although other accounts will suggest the evacuation occurs at an earlier or later time (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001, (Shortly Before 9:03 a.m.) September 11, 2001, and (9:30 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 305; National Institute of Standards and Technology 9/2005, pp. 109; Barrett and Collins 2006, pp. 34) OEM personnel therefore now have to operate from the their command bus. (Jenkins and Edwards-Winslow 9/2003, pp. 20 pdf file; 9/11 Commission 4/7/2004) The bus, known as the Interagency Command Center (ICC), is equipped with computers, a state-of-the-art communications system, and on-board electrical generation. It also has its own conference room. (Sandberg 9/21/2001; Jenkins and Edwards-Winslow 9/2003, pp. 20 pdf file; Power 2004, pp. 172) It can be deployed to the location of a major emergency, to serve as an on-scene command post for coordinating interagency operations and communications. (City of New York 2001, pp. 8 pdf file) The OEM’s emergency plans and vital records are kept in WTC 7, and, due to the evacuation of the command center, are now inaccessible. Fortunately, after they move to the ICC, OEM personnel are able to implement their emergency action plans from memory and by utilizing their combined knowledge. (Jenkins and Edwards-Winslow 9/2003, pp. 20 pdf file) After the Twin Towers collapse, the ICC will move to a firehouse on Houston Street, to provide support to Mayor Rudolph Giuliani and his entourage, who have set up a temporary headquarters at that location (see (After 10:28 a.m.-12:00 pm.) September 11, 2001). (Sandberg 9/21/2001; 9/11 Commission 4/7/2004)

A group from FAA headquarters, who are apparently oblivious to the morning’s crisis, request and are given a tour of the air traffic control tower at Washington’s Reagan National Airport, until they are forced to leave there just before the time of the Pentagon attack. (Spencer 2008, pp. 157-158) Reagan Airport is located less than a mile from the Pentagon. (Adair and Garza 10/3/2001)
Tour Group Wants to See Tower - At 9:32, the tower supervisor, Chris Stephenson, receives a phone call from one of the airport’s maintenance workers. The maintenance worker says he has a group there from the FAA’s Washington headquarters that is visiting the airport to go over some maintenance issues, but they are also curious to see what goes on in the control tower. It appears the FAA personnel are unaware of the attacks in New York, and Stephenson is asked if it is okay to bring them up. Though he is busy dealing with the chaos resulting from the ground stop recently ordered by the FAA’s Command Center (see (9:26 a.m.) September 11, 2001), Stephenson reluctantly agrees. The group arrives moments later, but Stephenson tries to ignore them. According to author Lynn Spencer, Stephenson is as yet unaware that an errant aircraft has been spotted heading toward Washington (see (9:33 a.m.) September 11, 2001). (Spencer 2008, pp. 157) But according to USA Today, the Secret Service warned him about this aircraft at around 9:30 a.m. (see (9:30 a.m.) September 11, 2001). (Levin 8/11/2002)
Group Ordered to Leave - Shortly after the group arrives, Stephenson is called by a controller at the TRACON and notified of the unidentified aircraft (presumably Flight 77), which is five miles west of the tower (see (9:36 a.m.) September 11, 2001). When he looks out the window, he sees it, now less than a mile away and approaching fast. Stephenson yells at the tour group: “Out! Get out!” The FAA group heads off down the stairs, but the last in the line looks out the window at the descending aircraft and asks, “What’s that guy doing?” ”Get out!” Stephenson repeats, and pushes the man into the stairwell. Soon afterwards, the Pentagon is hit (see 9:37 a.m. September 11, 2001). (Spencer 2008, pp. 158)

Bush’s motorcade on its way to the Sarasota airport.Bush’s motorcade on its way to the Sarasota airport. [Source: CBC]President Bush’s motorcade leaves the Emma E. Booker Elementary School in Sarasota, Florida, to take Bush and his entourage to Air Force One, but it initially heads in the wrong direction and has to turn around in order to proceed toward the airport. (Sammon 10/8/2002; Canadian Broadcasting Corporation 9/10/2006) Bush has just participated in a reading demonstration at the school (see 9:02 a.m. September 11, 2001) and given a brief statement to the nation in which he addressed the attacks on the World Trade Center (see 9:30 a.m. September 11, 2001). (White House 9/11/2001; Associated Press 8/25/2002) He now heads out of the school and gets into his limousine, which then speeds off to take him to his plane. (Sammon 2002, pp. 98-99; Rove 9/3/2013) Sarasota-Bradenton International Airport, where Air Force One is waiting, is three and a half miles away from the school. (Paltrow 3/22/2004 pdf file; Morell 9/2006 pdf file) Bush’s motorcade drives there much faster than it normally travels. Whereas it usually goes at around 40 to 45 miles per hour, on this occasion the vehicles are driven at 80 to 85 miles per hour. (Rove 9/3/2013) However, it initially speeds off in the wrong direction and, after several kilometers, the vehicles have to perform a U-turn in order to head toward the airport. (9/11 Commission 6/17/2004; Canadian Broadcasting Corporation 9/10/2006) During the journey, Bush notices people at the sides of the road, smiling and waving at him, apparently unaware of the crisis that is taking place. (Sammon 2002, pp. 98) The Secret Service is concerned that he might be attacked on his way to the airport and provides a high level of security for him during the journey (see (Between (Between 9:35 a.m. and 9:43 a.m.) September 11, 2001). (BBC 9/1/2002; Rove 2010, pp. 251; Graff 9/9/2016) Bush will learn about the attack on the Pentagon while he is being driven to the airport (see (Between 9:38 a.m. and 9:43 a.m.) September 11, 2001). His motorcade will arrive at the airport between 9:42 a.m. and 9:45 a.m. (see (9:43 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 39)

Personnel at NORAD’s Northeast Air Defense Sector (NEADS) are following Flight 93 while it is still flying west and before it reverses course, according to the accounts of some NEADS and NORAD officials, but their claims will be disputed by the 9/11 Commission. (Filson 2003, pp. 68, 71; 9/11 Commission 10/30/2003 pdf file; 9/11 Commission 8/26/2004, pp. 100-101)
NEADS Watches Flight 93 Heading West - Colonel Robert Marr, the battle commander at NEADS, will later recall that around this time, “his focus” is on Flight 93, which, he will say, is “circling over Chicago.” (9/11 Commission 10/27/2003 pdf file) Marr will tell author Leslie Filson that the flight is being monitored by NEADS personnel while it is still flying west. He will describe: “We don’t have fighters that way and we think [Flight 93 is] headed toward Detroit or Chicago. I’m thinking Chicago is the target.” Marr will say NEADS contacts an Air National Guard base in the area, “so they [can] head off 93 at the pass” (see (9:55 a.m.) September 11, 2001). (Filson 2003, pp. 68)
NORAD Watching Flight 93 When It Changes Course - Lieutenant Colonel Mark Stuart, an intelligence officer who is in the NEADS battle cab with Marr, will give a similar account. He will say that when the Flight 93 “incident began to unfold,” it was his “professional judgment that the plane was going to strike the Sears Tower in Chicago, and he passed that judgment to Colonel Marr.” (9/11 Commission 10/30/2003 pdf file) And Major General Larry Arnold, the commander of the Continental United States NORAD Region, will say that NORAD personnel are already following Flight 93 at 9:36 a.m., when it reverses course and heads back east (see (9:36 a.m.) September 11, 2001). He will tell Filson, “[W]e watched the 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward [Washington,] DC.” (National Transportation Safety Board 2/19/2002 pdf file; Filson 2003, pp. 71; 9/11 Commission 8/26/2004, pp. 41) Marr will similarly say “that he distinctly remembers watching [Flight 93] come west and turn over Cleveland.” (9/11 Commission 1/23/2004 pdf file)
9/11 Commission Says No One at NORAD Watches Flight 93 - However, the 9/11 Commission will dispute these accounts. It will state: “The record demonstrates… that no one at any level in NORAD… ever ‘watched the 93 track’ start to turn south towards Washington, DC. In fact, the military never saw Flight 93 at all.” (9/11 Commission 8/26/2004, pp. 101) NEADS will first be alerted to Flight 93 significantly later, at 10:07 a.m., according to the 9/11 Commission (see 10:05 a.m.-10:08 a.m. September 11, 2001).
Officer May Have Confused Flight 93 with Delta 1989 - The 9/11 Commission will suggest to Marr that he was mistaking Flight 93 for Delta Air Lines Flight 1989, an aircraft that is incorrectly reported as having been hijacked around this time (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001). Marr will respond that he may have confused Flight 93 with Delta 1989, but say that “he believes the last point at which he saw Flight 93 was when it was over Ohio, before it turned off its transponder,” which happens at 9:41 a.m. (see (9:40 a.m.) September 11, 2001). (9/11 Commission 1/23/2004 pdf file; 9/11 Commission 7/24/2004, pp. 27-30) Senior officials, including Marr and Arnold, will claim that the US military continues following Flight 93 after it reverses course and is heading toward Washington (see (9:36 a.m.-10:06 a.m.) September 11, 2001). (Filson 2003, pp. 71, 73) Stuart will say that after Flight 93 changes course, he “and other NEADS people knew it was headed to DC.” (9/11 Commission 10/30/2003 pdf file)

Eric Shinseki.Eric Shinseki. [Source: US Army]Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, is informed that a hijacked aircraft is thought to be heading toward Washington, DC, and is possibly aiming for the Pentagon. Chiarelli was in his office at the Pentagon, preparing to go to a scheduled meeting, when he learned of the attacks on the World Trade Center. In response, he instructed a colleague to activate the Army’s Crisis Action Team (CAT) (see (Shortly After 9:03 a.m.) September 11, 2001). Shortly after doing so, he was phoned by General Eric Shinseki, the Army’s chief of staff who is currently in Singapore, attending a conference. Shinseki asked for a situation report. “All I could tell him, basically, was what I had seen on TV,” Chiarelli will later recall. “I didn’t have any time to leave the room, to go to the CAT, to check with the intel folks,” he will add. Now, while Chiarelli is still on the phone with Shinseki, Oscar Benjamin, an analyst in the Army’s Antiterrorism Operations Intelligence Cell (ATOIC), comes into his office. (Chiarelli 2/5/2002; Rossow 2003, pp. 65; Lofgren 2011, pp. 95-98) The ATOIC is responsible for providing terrorism early warning to the Army. (University of Wisconsin 2/25/2009) Benjamin reports that additional aircraft have been hijacked and one of these aircraft is thought to be heading toward Washington—“in his opinion for the Pentagon,” according to author Robert Rossow. Chiarelli passes this information on to Shinseki. Realizing there is little he can do from Singapore, Shinseki says he will call back later and ends the call. Chiarelli then heads to the Army Operations Center in the basement of the Pentagon, where the CAT is assembling. Just after he arrives on the CAT floor, one of his intelligence officers (possibly Benjamin, although this is unstated) comes in and, he will recall, tells him “that they had credible information that one of the [additional hijacked] aircraft was headed for DC.” Chiarelli will then hear the sound of the impact as the Pentagon is hit. (Chiarelli 2/5/2002; Rossow 2003, pp. 65-66; Lofgren 2011, pp. 98-99) (The Pentagon is hit at 9:37 a.m. (see 9:37 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 10) )

The Pentagon explodes. 
The Pentagon explodes. [Source: Donley/ Sipa]Flight 77 crashes into the Pentagon. All 64 people on the plane are killed. A hundred-and-twenty-four people working in the building are killed, and a further victim will die in hospital several days later. Hijackers Hani Hanjour, Khalid Almihdhar, Majed Moqed, Nawaf Alhazmi, and Salem Alhazmi presumably are killed instantly. (Typically, they are not included in the death counts.) (CNN 9/17/2001; North American Aerospace Defense Command 9/18/2001; Ellison 10/17/2001; Vogel 11/21/2001; Levin, Adams, and Morrison 8/12/2002; Associated Press 8/21/2002; MSNBC 9/3/2002; ABC News 9/11/2002; CBS 9/11/2002) Flight 77 hits the first floor of the Pentagon’s west wall. The impact and the resulting explosion heavily damage the building’s three outer rings. The path of destruction cuts through Army accounting offices on the outer E Ring, the Navy Command Center on the D Ring, and the Defense Intelligence Agency’s comptroller’s office on the C Ring. (Vogel 2007, pp. 431 and 449) Flight 77 strikes the only side of the Pentagon that had recently been renovated—it was “within days of being totally [renovated].” (US Department of Defense 9/15/2001) “It was the only area of the Pentagon with a sprinkler system, and it had been reconstructed with a web of steel columns and bars to withstand bomb blasts. The area struck by the plane also had blast-resistant windows—two inches thick and 2,500 pounds each—that stayed intact during the crash and fire. While perhaps, 4,500 people normally would have been working in the hardest-hit areas, because of the renovation work only about 800 were there.” More than 25,000 people work at the Pentagon. (Schrader 9/16/2001) Furthermore, the plane hits an area that has no basement. As journalist Steve Vogel later points out, “If there had been one under the first floor, its occupants could easily have been trapped by fire and killed when the upper floors collapsed.” (Vogel 2007, pp. 450)

General John Keane, vice chief of staff of the Army, initially goes to assist people near the crash site after the Pentagon is hit but subsequently goes to the Army Operations Center (AOC) in the basement of the Pentagon to help the military respond to the terrorist attacks. Keane ordered Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization, to bring the AOC up to full manning after he learned a plane had crashed into the World Trade Center (see (Between 8:49 a.m. and 9:02 a.m.) September 11, 2001). (Keane 9/10/2016; Swift 9/11/2016) The AOC is “the Army’s command and control center,” according to Chiarelli. (Schwab and Jewell 9/2004) It is “the place that people will migrate” to during an emergency, according to Brigadier General Clyde Vaughn, the Army’s deputy director of operations, readiness, and mobilization. (Vaughn 2/12/2002) And yet Keane did not go there himself in response to the attacks on the WTC and was still in his office when the Pentagon was hit. Although his office is located far away from where the attack occurred, it shook violently from the impact and subsequently started filling with smoke.
Keane Tells His Staffers to Go Home - Following the attack, Keane tells his immediate staff to call home and then evacuate. “Look, call your homes right now and make sure everybody knows you’re alright,” he says, “and then I want you to all to leave the building immediately.” He keeps just his executive officer and his aide with him, and decides to head to the scene of the attack. “Let’s go on down there and see if we can help some of these people,” he says. Keane and his colleagues grab some T-shirts, soak them in water, and wrap them around their noses and mouths for protection. They then make their way toward the crash site.
Keane Is Advised to Go to the Operations Center - About 100 yards from it, the smoke becomes thicker. People there are running away from the area of the attack. Keane and his two colleagues take time ensuring that everyone is able to get out of the Pentagon. After a while, though, Keane’s executive officer determines that they should be in the AOC. He tells Keane: “Look, you’ve got to take charge of the Army, so let’s get to the operations center. We’ll leave the recovery to other people.” “I knew immediately that he was right,” Keane will later comment. He and his two colleagues therefore go to the AOC. (Keane 9/10/2016; Swift 9/11/2016)
Keane Provides 'Leadership and Guidance' - When they get there, Keane talks to Chiarelli, who went to the operations center before the Pentagon was hit, and asks him for a situation report. Chiarelli says what he currently knows about the attacks. “I was able to tell [Keane] basically what had occurred at the World Trade Center,” he will recall, adding, “We were able to tell him that the [Pentagon] had been hit—he knew the building had been hit—and that there were other aircraft in the air.” (Chiarelli 2/5/2002; Lofgren 2011, pp. 100) Keane subsequently provides “leadership and guidance” to the personnel in the AOC, according to a report published by the Army. (Christopher N. Koontz 2011, pp. 56 pdf file) He apparently stays in the operations center for the rest of the day. (Keane 9/10/2016; Swift 9/11/2016) Other senior Army leaders also go to the AOC following the attack on the Pentagon. (Chiarelli 2/5/2002; Rossow 2003, pp. 67; Goldberg et al. 2007, pp. 135)

Stacia Rountree.Stacia Rountree. [Source: Vanity Fair]Colin Scoggins, the military liaison at the FAA’s Boston Center, contacts NORAD’s Northeast Air Defense Sector (NEADS) and incorrectly notifies it that another aircraft, Delta Air Lines Flight 1989, is a possible hijacking. (9/11 Commission 2004; Bronner 8/1/2006) Boston Center previously called NEADS at 9:27 and said that Delta 1989 was missing (see 9:27 a.m. September 11, 2001). (North American Aerospace Defense Command 9/11/2001; 9/11 Commission 5/23/2003)
NEADS Technicians Respond - At NEADS, Stacia Rountree, the ID technician who takes Scoggins’s call, announces to her colleagues: “Delta ‘89, that’s the hijack. They think it’s possible hijack.… South of Cleveland.” The plane’s transponder is still on, and she adds, “We have a code on him now.” Rountree’s team leader, Master Sergeant Maureen Dooley, instructs: “Pick it up! Find it!” The NEADS technicians quickly locate Delta 1989 on their radar screens, just south of Toledo, Ohio, and start alerting other FAA centers to it. (Bronner 8/1/2006; Spencer 2008, pp. 177) NEADS mission crew commander Major Kevin Nasypany will be notified by his staff of the suspected hijacking at about 9:41 or 9:42 a.m. (9/11 Commission 1/22/2004 pdf file) NEADS never loses track of Delta 1989. It will follow it on radar as it reverses course over Toledo, heads east, and then lands in Cleveland (see (10:18 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 28) It will order Air National Guard fighter jets from Selfridge and Toledo to intercept the flight (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001). (Spencer 2008, pp. 178-179) But it will soon learn that Delta 1989 is not in fact hijacked. (9/11 Commission 7/24/2004, pp. 28)
Cleveland Center, Not Boston, Handling Delta 1989 - Although Boston Center notifies NEADS of the suspected hijacking, Delta 1989 is in fact being handled by the FAA’s Cleveland Center. (Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 7/24/2004, pp. 10-12) Cleveland Center air traffic controllers suspected that Delta 1989 had been hijacked at around 9:30 a.m. (see (9:28 a.m.-9:33 a.m.) September 11, 2001), but apparently only informed the FAA’s Command Center, and not NEADS, of this. (Adams, Levin, and Morrison 8/13/2002) To explain why Boston Center alerts NEADS to the flight, the 9/11 Commission will later comment that, “Remembering the ‘we have some planes’ remark” (see 8:24 a.m. September 11, 2001), the Boston Center simply “guessed that Delta 1989 might also be hijacked.”
Similar to First Two Hijacked Planes - Like Flights 11 and 175, the two aircraft that have crashed into the World Trade Center (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001), Delta 1989 took off from Boston’s Logan Airport. (9/11 Commission 7/24/2004, pp. 27-28) According to the New York Times, it left there at about the same time as Flights 11 and 175 did, meaning around 8:00 to 8:15 a.m. (Wald and van Natta 10/18/2001; 9/11 Commission 7/24/2004, pp. 32) Like those two aircraft, it is a Boeing 767. (Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 7/24/2004, pp. 27-28) But, unlike those flights, its transponder has not been turned off, and so it is still transmitting a beacon code. (9/11 Commission 7/24/2004, pp. 28; Bronner 8/1/2006) It is unclear what Delta 1989’s intended destination is. According to some accounts, like Flights 11 and 175 were, it is bound for Los Angeles. (Singer 9/11/2001; Wald and van Natta 10/18/2001; Adams, Levin, and Morrison 8/13/2002; Velez 9/24/2007; Spencer 2008, pp. 167) Other accounts will say that its destination is Las Vegas. (9/11 Commission 7/24/2004, pp. 28; Bronner 8/1/2006) Personnel at NEADS are apparently informed that Las Vegas is the intended destination. Around this time, one member of staff there tells her colleagues that the flight is “supposed to go to Vegas.” (North American Aerospace Defense Command 9/11/2001)
One of Numerous Incorrect Reports - The 9/11 Commission will comment: “During the course of the morning, there were multiple erroneous reports of hijacked aircraft (see (9:09 a.m. and After) September 11, 2001). The report of American 11 heading south was the first (see 9:21 a.m. September 11, 2001); Delta 1989 was the second.” (9/11 Commission 7/24/2004, pp. 28)

Marc Sasseville.Marc Sasseville. [Source: CBC]Four pilots with the District of Columbia Air National Guard (DCANG) at Andrews Air Force Base, near Washington, finally receive authorization to get airborne in their fighter jets, and are given instructions on their mission. The pilots are Lieutenant Colonel Marc Sasseville, Lieutenant Heather Penney Garcia, Captain Brandon Rasmussen, and Major Daniel Caine.
Pilot Waiting 'for Somebody to Task Me with Something' - Rasmussen will later recall that, although he and his colleagues at the unit had been aware of the attacks in New York, it is only after the Pentagon is hit (see 9:37 a.m. September 11, 2001) that “we knew that we were going to be sticking around home and being quite busy.” And until the pilots are authorized to take off, he is “just kind of standing back, waiting for somebody to task me with something.” He will recall, “I was just waiting at the ops desk for someone to say, ‘Okay, we’ve been cleared to take off and go.’”
Sasseville Briefs Other Pilots - Rasmussen says that, after Sasseville and Caine receive authorization from their wing commander to get airborne and to use missiles, Sasseville, who is the acting operations group commander, looks at Penney Garcia and says, “You’re flying with me, and [Caine] you’re flying with [Rasmussen], do suit up and get out there as quick as possible.” According to another account, Sasseville gives his three fellow pilots a short briefing, telling them: “I have no idea what’s going on, but we’re flying. Here’s our frequency. We’ll split up the area as we have to. Just defend as required. We’ll talk about the rest in the air.” (Scott 9/9/2002; Filson 2003, pp. 82-84; Rasmussen 9/18/2003) Sasseville will recall, “There wasn’t a whole hell of a lot to talk about, because we didn’t know what was going on.” (Vogel 2007, pp. 446)
Pilots Prepare to Fly - According to Rasmussen: “We were relieved to actually be given permission to go up and do something instead of feeling totally helpless. I mean we are fighter pilots, just like guard dogs chomping at the bit ready to go.” The four pilots run down the hallway and throw on their gear, grabbing their helmets, g-suits, and parachute harnesses, before heading to the operations desk to get their aircraft assignments. (Scott 9/9/2002; Rasmussen 9/18/2003)
Commander Gives Instructions - According to author Leslie Filson, before Sasseville and Penney Garcia head to their jets, Brigadier General David Wherley, the commander of the DC Air National Guard, gives them instructions, regarding their mission. As Wherley will later recall, “My translation of the rules [of engagement] to [Sasseville] was, ‘You have weapons free flight-lead control.’” (Filson 2003, pp. 82) “Weapons free” means the decision whether to shoot at a hostile aircraft rests with the lead pilot. (9/11 Commission 7/24/2004, pp. 44) Wherley says, “Do you understand what I’m asking you to do?” and both pilots respond, “Yes.” Wherley then tells them to be careful. “It was important for them to understand that this was weapons free,” he will recall. (Filson 2003, pp. 82) However, Sasseville will tell the 9/11 Commission that he does not remember receiving the rules of engagement he is supposed to follow until later on, after he has taken off. (9/11 Commission 3/8/2004 pdf file)
Jets Don't Launch until 10:42 and After - The exact times when the four pilots are authorized to get airborne and receive their mission instructions are unclear. But Sasseville and Penney Garcia will take off from Andrews at 10:42 a.m., with their planes armed only with guns, and no missiles (see 10:42 a.m. September 11, 2001). Rasmussen and Caine take off at 11:11 a.m., by which time their jets have been armed with missiles (see 11:11 a.m. September 11, 2001). (Filson 2003, pp. 82-84; 9/11 Commission 2004)

Alice Hoglan, the mother of Mark Bingham, a passenger on Flight 93, informs the FBI that her son has just phoned her from the plane, and then calls Bingham’s cell phone and leaves two voicemail messages. (Federal Bureau of Investigation 9/17/2001; Barrett 2002, pp. 157-158) Alice Hoglan is currently staying at the home of her brother, Vaughn Hoglan, and his wife in Saratoga, California. (Longman 2002, pp. 129; Ganahl 9/10/2003) Bingham has just called her and told her his flight was taken over by three men who said they had a bomb, but the call got broken off after less than three minutes (see (9:37 a.m.) September 11, 2001). (Federal Bureau of Investigation 9/11/2001; 9/11 Commission 5/13/2004 pdf file; 9/11 Commission 8/26/2004, pp. 41, 99)
Bingham's Mother Realizes Flight 93 Will Likely Crash - No one in the Hoglan household was aware of the terrorist attacks in New York and at the Pentagon. But after the call from Bingham ends, Vaughn Hoglan switches on the television to see if there is any news about Flight 93 and the family sees, for the first time, the recorded footage of Flight 175 crashing into the World Trade Center (see 9:03 a.m. September 11, 2001). (BBC 12/2001; Barrett 2002, pp. 157) Alice Hoglan then realizes the hijacking of Flight 93 is part of a “grand and ugly scheme,” and that her son’s plane will likely crash, too. (Yun 1/28/2005; Sulek 9/10/2011)
Bingham's Mother Tells the FBI about the Hijacking - Being a flight attendant with United Airlines, she calls her airline to ask about her son’s plane. (Sanchez 8/25/2011) However, she will later recall, all she gets is a recorded message, which states, “United Flight 93 left Newark at 8:01 a.m. and will arrive San Francisco, Gate 82, at 11:19 a.m.” (BBC 12/2001) She also calls 9-1-1 to report what has happened. She is put through to the San Francisco division of the FBI and speaks to an agent there. (Federal Bureau of Investigation 9/17/2001) The agent asks her a series of questions about the hijackers on Flight 93, but she is unable to answer them.
Bingham's Mother Leaves Messages for Her Son - Alice Hoglan then tries calling her son twice on his cell phone, intending to let him know the full scale of the attack that his plane’s hijacking is part of. On both occasions, she has to leave messages on his voicemail. She makes the first call at 9:54 a.m. (Because she is flustered, she miscalculates the East Coast time by an hour during the call and also mistakenly says Flight 93 might be used as a “target” rather than as a “weapon.”) She says: “Mark, this is your mom. It’s 10:54 a.m. [Eastern Time]. The news is that it’s been hijacked by terrorists. They are planning to probably use the plane as a target to hit some site on the ground. So, if you possibly can, try to overpower these guys if you can, ‘cause they will probably use the plane as a target. I would say go ahead and do everything you can to overpower them, because they’re hellbent. Try to call me back if you can. You know the number here. Okay, I love you sweetie. Bye.” A minute or so later she calls Bingham’s cell phone again and leaves a second, similar message. Among other things, she urges her son to “group some people and perhaps do the best you can to get control of [the plane].” (Barrett 2002, pp. 157-158; Sulek 9/10/2011; McMillan 2014, pp. 122) Bingham will never receive these messages. (ABC News 3/30/2002) His plane will crash in a field in Pennsylvania at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001).

An F-16C Fighting Falcon of the 148th Fighter Wing.An F-16C Fighting Falcon of the 148th Fighter Wing. [Source: Brett R. Ewald / US Air Force]NORAD’s Northeast Air Defense Sector (NEADS) tries to get fighter jets from a military unit in Duluth, Minnesota, sent after Delta Air Lines Flight 1989, but the unit is unable to respond. (9/11 Commission 1/22/2004 pdf file) NEADS has been contacted by the FAA’s Boston Center and incorrectly told that Delta 1989 is a possible hijacking (see 9:39 a.m. September 11, 2001). The aircraft is just south of Toledo, Ohio, and Colonel Robert Marr and Major Kevin Nasypany order the troops at NEADS to call Air National Guard bases in that area to see if any of them can launch fighters. (9/11 Commission 2004; Bronner 8/1/2006)
NEADS Calls Duluth - The staff attempts to get a unit in Duluth to send jets toward the Delta flight. (9/11 Commission 1/22/2004 pdf file; 9/11 Commission 1/23/2004 pdf file) Presumably the unit they call is the 148th Fighter Wing of the Minnesota Air National Guard, which is located at the Duluth International Airport and flies the F-16 Fighting Falcon. (GlobalSecurity (.org) 8/21/2005) Unlike Otis Air National Guard Base and Langley Air Force Base, the 148th FW at Duluth is not one of NORAD’s seven “alert” sites around the US. However, its mission does include “air superiority and air defense functions.” (McKenna 12/1999; US Air Force 2004; 9/11 Commission 7/24/2004, pp. 17)
Duluth Has 'Nobody Available' - The Duluth unit is unable to respond to NEADS’s request for help. (9/11 Commission 1/22/2004 pdf file) The reason for this is unclear. At 9:46 a.m., a member of staff on the NEADS operations floor will report that “Duluth has night flying, so there’s nobody available.” (North American Aerospace Defense Command 9/11/2001; Donaldson and Johnson 6/2008, pp. 47 pdf file) Marr will subsequently instruct NEADS personnel to contact every Air National Guard unit in the Northeast US with instructions to get their fighters airborne (see (Between 9:50 a.m. and 10:00 a.m.) September 11, 2001). NEADS will also order Air National Guard jets from Selfridge and Toledo to intercept Delta 1989 (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001).

John Keane.John Keane. [Source: US Army]The Army’s Crisis Action Team (CAT) at the Pentagon is “formally stood up” and its members respond to the terrorist attacks. (Rossow 2003, pp. 66; Goldberg et al. 2007, pp. 135; Cohn 9/8/2011) Lieutenant Colonel Kevin Stramara activated the CAT after the second hijacked aircraft crashed into the World Trade Center, at 9:03 a.m., on the orders of Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization (see (Shortly After 9:03 a.m.) September 11, 2001). (Chiarelli 2/5/2002; Lofgren 2011, pp. 96-97) Chiarelli’s intention was, he said, “to respond to the contingency in New York if requested by state and local officials.” (Goldberg et al. 2007, pp. 134) The CAT is now “formally stood up,” according to author Robert Rossow, although exactly what this means is unstated.
Senior Officials Come to Operations Center - When the CAT is activated, its members assemble in the Army Operations Center (AOC) in the basement of the Pentagon. (Rossow 2003, pp. 64, 66) Numerous senior officials now start arriving in the AOC. These include General John Keane, vice chief of staff of the Army; Brigadier General Clyde Vaughn, deputy director of operations, readiness, and mobilization; Major General Philip Kensinger, assistant deputy chief of staff for operations and plans; and Thomas White, the secretary of the Army. More senior officers come to the AOC than would usually be the case in a crisis, according to Chiarelli, “because a large portion of the Army section of the building had been destroyed” in the attack on the Pentagon. “People had been forced out of their space,” he will later say, and “were looking for some place to go.” (Chiarelli 2/5/2002; Vaughn 2/12/2002; Goldberg et al. 2007, pp. 135; Lofgren 2011, pp. 98-101; Baier 9/12/2011)
Operations Center Personnel Unaware that a Plane Hit the Pentagon - Chiarelli arrived at the AOC shortly before the Pentagon was hit (see (Shortly Before 9:37 a.m.) September 11, 2001) and, he will recall, heard a “muffled noise” when the attack occurred, at 9:37 a.m. (see 9:37 a.m. September 11, 2001). (Chiarelli 2/5/2002; Lofgren 2011, pp. 98-99) Colonel Henry Huntley, who also arrived at the AOC around the time of the Pentagon attack, will recall, “Alarms started going off and there was an announcement that an explosion had gone off in the building.” (Ellich 7/8/2008) However, those in the AOC are apparently initially unaware that a plane has hit their building. Vaughn, who witnessed the attack from the road outside the Pentagon, calls Major George Sterling, the AOC commandant, and says to him, “You know that you’ve been hit by an airplane?” Sterling responds, “Is that what happened?” Vaughn will comment that “many people… didn’t find out for some time” that the Pentagon had been hit by an airplane. (Vaughn 2/12/2002; Rossow 2003, pp. 15-16; Lofgren 2011, pp. 3-4)
Support Agency Commander Unaware that the US Is under Attack - Colonel Bruce Bachus, commander of the Command and Control Support Agency, who is responsible for keeping the AOC operating, arrived at the Pentagon around the time the attack there occurred and yet he is unaware of the crisis taking place in the US when he gets to the AOC. In the AOC, Dick Mansfield, deputy director of the Command and Control Support Agency, says to him: “We’ve been hit! The CAT has been stood up!” But Bachus appears to be puzzled. Mansfield therefore asks him, “Sir, do you know what’s going on?” Bachus says no and that he had not been listening to the radio—like he usually does—while he drove to work. He says he heard a loud sound while he was in the Pentagon’s A-E Drive, and saw people shouting and running down the corridors, but he’d had no idea what was going on. Mansfield therefore has to quickly brief him on the catastrophic events of the past hour. (Rossow 2003, pp. 9, 68)
Crisis Team Assesses How Many Army Staffers Are Missing - The “first big task” for the CAT, according to Vaughn, is “to get a count on how many people were missing on the Army staff.” Chiarelli instructs Vaughn to focus on this assignment. Vaughn then announces on the CAT floor that he wants each section “to start that process of figuring out who was missing and who was not.” “For a long time, our number one priority was locating and identifying and taking care of… our soldiers and civilians,” Vaughn will say. (Vaughn 2/12/2002) Lieutenant Colonel Richard Kotch, who is working in the AOC this morning, will recall that those in the operations center also “assured continuity of operations after the impact [i.e. the attack on the Pentagon].” (Cohn 9/8/2011)
Intelligence Officers Give Inaccurate Reports of Hijackings - Meanwhile, after he arrives at the AOC, Chiarelli receives reports from his intelligence officers informing him, inaccurately, about additional hijacked aircraft. He is told there are “a minimum of four aircraft that were hijacked and a possibility, at one time, [of] as high as seven.” (Chiarelli 2/5/2002; Lofgren 2011, pp. 99)
Operations Center Has Sophisticated Equipment - The CAT, according to Soldiers magazine, “consists of a dedicated ‘hot’ desk with classified and unclassified computers, and secure telephones for 24 separate Army staff sections.” (Schwab and Jewell 9/2004) The AOC, where its members assemble, is equipped with state-of-the-art communications equipment and has television sets for monitoring news coverage. (Vogel 8/25/1995) A glassed-in balcony overlooks the main floor and four giant screens are on the wall above the computer workstations. (Chiarelli 2/5/2002; Lofgren 2011, pp. 99-100)
Watch Team Regularly Communicates with Government Agencies - AOC personnel usually work around the clock to keep senior Army leaders aware of issues and events around the world. A watch team monitors the world constantly and is ready to sound the alarm if a crisis erupts somewhere. The watch team also “directs hundreds of communications daily to the FBI, the State Department, the White House command center, local law enforcement agencies, and others,” according to Soldiers magazine. The AOC is equipped with an “emergency action console,” which is a switchboard with a sophisticated communications system that allows watch team members to contact, at the touch of a button, the White House, the secretary of defense’s office, and Army commands around the world. (Vogel 8/25/1995; Schwab and Jewell 9/2004) The CAT will become “a focal point for all Pentagon activities” in response to the terrorist attacks, according to Kotch. (Cohn 9/8/2011) It will continue working around the clock in the aftermath of the attacks. (Chiarelli 2/5/2002)

Donald Cook.Donald Cook. [Source: US Air Force]Lieutenant General Donald Cook, acting commander of the Air Combat Command (ACC), receives a call in which he is told the White House wants to know how quickly the Predator drone, a remotely controlled, unmanned plane, can be deployed over Afghanistan. Cook, who is currently at ACC headquarters at Langley Air Force Base, Virginia, receives the call “less than one hour after” the first hijacked plane crashed into the World Trade Center (see 8:46 a.m. September 11, 2001), according to journalist and author Richard Whittle, which means the call is made before around 9:45 a.m. The caller, Whittle will write, says that the “White House [wants] to know how soon the Air Force could get three Predators over Afghanistan—with missiles under their wings.” The identity of the caller is unstated. Later this morning, Cook will talk to Colonel Ed Boyle, director of intelligence for the ACC, who is away in Arizona, and pass on this information to him (see (After 10:00 a.m.) September 11, 2001). (Whittle 2014, pp. 236; Whittle 3/2015) The first Predator mission over Afghanistan will take place on September 18 and on October 7, the first day of the war in Afghanistan, the first armed Predator mission will be flown (see September 18-October 7, 2001 and October 7, 2001).

[Source: Associated Press]The White House is evacuated after the Secret Service receives what the Associated Press describes as a credible threat of a terrorist attack against it. (Associated Press 2001 pdf file; CNN 9/11/2001; CNN 9/12/2001) Minutes earlier, in the White House Situation Room, Secret Service Director Brian Stafford informed counterterrorism “tsar” Richard Clarke that an aircraft was heading in their direction, and said he was going to order the evacuation of the White House (see (9:37 a.m.) September 11, 2001). (Clarke 2004, pp. 7) The Secret Service learned of this aircraft by monitoring radar and over an open line with the FAA (the “hijack net”), which enable them to receive real time information about the hijacked aircraft. The Secret Service, which has been using an air surveillance system called Tigerwall for some time (see (September 2000 and after)), tracks both American 77 and United 93 as they approach Washington and assumes the White House is a target. Secret Service agent Barbara Riggs will later say, “The Secret Service prepared to defend the facility,” although the precise nature of the preparations is unclear. (New York Times 9/12/2001; MSNBC 9/22/2001; Langley 12/16/2001; Balz and Woodward 1/27/2002; Associated Press 8/21/2002; 9/11 Commission 6/17/2004; PCCW Newsletter 3/2006) A slow and orderly evacuation of the White House had in fact begun earlier on (see (9:20 a.m.) September 11, 2001). But now the Secret Service orders people to run so as to evacuate faster. (CNN 9/11/2001; ABC News 9/11/2002)

Engine Company 16.Engine Company 16. [Source: District of Columbia Fire and Emergency Medical Services Department]The District of Columbia Fire Department (DCFD) sends engines to the White House after the Secret Service incorrectly reports that a plane has crashed into the presidential residence and the building is on fire. As well as reporting the supposed plane crash and fire, the Secret Service says the White House, or at least part of it (the specific details are unclear), has collapsed. In response to the report, the fire communications center dispatches a “box alarm” from Engine Company 16, the station that serves the White House. (Witt 9/21/2001; Ward 4/2002 pdf file; Smith 10/31/2002) A box alarm consists of four engines, two trucks, a rescue company, and a battalion chief. (Ward 4/2002 pdf file) Since the alleged incident is at the White House—the home of the US president—the response is increased by sending an additional battalion chief and the deputy fire chief, Rogers Massey, to deal with it. And because a building collapse has been reported, the DCFD’s cave-in task force, which comprises Rescue 3, Battalion Chief 3, Engine 15, and the hazmat (hazardous materials) task force, is also sent. However, when the crews arrive at the White House, they are promptly told to leave. A uniformed Secret Service officer waves them away and says: “Get the f_ck outta here! There’s a plane coming in!” Lieutenant Jeff Wright, one of the firefighters involved in the response, will later recall the turn of events, saying: “It was mass confusion. We go down to the White House and no one knows what’s going on. We could see smoke coming from Virginia [where the Pentagon is located].” The report of the incident at the White House is investigated and determined to be unfounded. However, after he receives intelligence reports from the FBI, Special Operations Battalion Chief Michael Sellitto decides he will keep his units near the White House in case attacks should subsequently occur there or at the Capitol building. (Witt 9/21/2001; Ward 4/2002 pdf file; Smith 10/31/2002) The DCFD will also respond to the attack on the Pentagon, which occurred at 9:37 a.m. (see 9:37 a.m. September 11, 2001). It will dispatch a box alarm to the Department of Defense’s headquarters at around 9:48 a.m. (DCFD (.com) 9/12/2001; Witt 9/21/2001; Goldberg et al. 2007, pp. 72)

A man who is on the 105th floor of the South Tower calls emergency 9-1-1 to report that floors below his location, “in the 90-something floor,” have collapsed. The 9-1-1 operator types a record of this call into the Special Police Radio Inquiry Network (SPRINT) data link, which will be passed on to the New York fire department’s Emergency Medical Service (EMS). It isn’t known when the call is made exactly, but the EMS Dispatch computer apparently receives the call record at this time. However, because it is classified as a “supplement message,” it is not yet read by anyone. The police dispatcher dealing with the area around the WTC also receives the call record, but misinterprets it as meaning that the floor the person is on has collapsed. EMS dispatchers are dealing with an enormous volume of calls as well as performing many other tasks under extreme pressure during the crisis, so a report later concludes that the EMS operators didn’t have the time to review the information before the collapse of the South Tower at 9:59 (see 9:59 a.m. September 11, 2001), and the fire chiefs never received the information.

(Associated Press 8/21/2002) It is the first time in US history this has ever happened. (Zuckman 9/12/2001; Mitchell and Seelye 9/12/2001) Both the Senate and the House are in session at the time. (CNN 8/17/2002) Capitol Police officers go through the building and order people to leave at once. (Lancaster and Dewar 9/12/2001; CNN 9/11/2002)
Reports of Plane Approaching the Capitol - The evacuation appears to be in response to reports of a plane heading toward the Capitol. (Associated Press 9/11/2001; CNN 8/17/2002; Bamford 2004, pp. 80-81) According to CNN congressional correspondent Dana Bash, “the Capitol Police were hearing, in their radio, that there was a plane—another plane in the air, likely headed for the Capitol.” (CNN 9/11/2006) When a Capitol Police officer instructs Senate Majority Leader Tom Daschle (D-SD) to leave the building, he says: “We have word that an airplane is heading this way and could hit the building anytime. You need to evacuate.”
'Nothing Orderly' about Evacuation - However, there are problems with the evacuation. According to Daschle, “The fire alarm system, which was working in the nearby Senate office buildings, was never activated in the Capitol, so there were people who weren’t aware that an evacuation was taking place.” Also, some individuals are reluctant to leave. (Daschle and D'Orso 2003, pp. 109-110) Rep. Bob Stump (R-AZ) will recall: “They tried to throw me out three times, but they didn’t succeed. I figured I was safer in the building than out on the street.” (Associated Press 9/11/2001) Daschle will recall that there is “nothing orderly” about the evacuation. Outside the building “No one knew what to do or where to go. People congregated on the grass and in the parking lot. Senators and staff were mixed in with tourists, all staring up at the sky, wondering what might be headed our way.” (Daschle and D'Orso 2003, pp. 110) CNN will report, “[S]ome of the most high ranking officials in the United States government were just kind of scattered around this area without a gathering point.” (CNN 9/11/2006)
Sergeant at Arms Concerned over Poor Security - Al Lenhardt, the Senate’s sergeant at arms, will later say how alarmed he was “to see members of Congress and their staffs mixed in with visitors and passersby wandering in the open around the Capitol grounds. One of the tactics that terrorists have been known to employ is to create a diversion to move their intended target to the area where the actual attack will take place. Al imagined a bomb or gunfire erupting right there on the lawn outside the Capitol.” (Daschle and D'Orso 2003, pp. 111) Eventually, many of the members of Congress go to the Capitol Police headquarters, which then serves as their command center for the day (see (9:55 a.m. and After) September 11, 2001 and (10:00 a.m.-6:30 p.m.) September 11, 2001).

After spending about 40 minutes at the disaster scene, on the World Trade Center site, New York City Mayor Rudolph Giuliani relocates to a small office building at 75 Barclay Street, about two blocks from the WTC, hoping to establish a command post there. His usual command center, in WTC 7, was evacuated at around 9:30 a.m. (see (9:30 a.m.) September 11, 2001). With him are several colleagues, including Police Commissioner Bernard Kerik and Office of Emergency Management Director Richard Sheirer. (Kerik 2001, pp. 334; Giuliani 2002, pp. 10; 9/11 Commission 5/18/2004 pdf file; 9/11 Commission 5/19/2004; Barrett and Collins 2006, pp. 10) While at Barclay Street, Giuliani is able to get in touch with the White House, and speaks to Chris Henick, the deputy political director to President Bush (see 9:58 a.m. September 11, 2001). Immediately afterwards, he receives a phone call from Vice President Cheney, though this is cut off before either one is able to speak. Giuliani also claims he is given advance warning of the South Tower’s collapse while at this command post (see (Before 9:59 a.m.) September 11, 2001). After the South Tower collapses outside, Giuliani and his colleagues all decide to evacuate, going through the basement into a neighboring building, 100 Church Street. They will then leave this and head north, being joined by cameras and press. (Fink and Mathias 2002, pp. 112; 9/11 Commission 5/19/2004; Barrett and Collins 2006, pp. 348)

Ronald Bucca.
Ronald Bucca. [Source: Public domain]Two firefighters climbing up the South Tower, Orio Palmer and Ronald Bucca, have reached its 78th floor, the lower end of the impact zone where Flight 175 hit. (Dwyer and Fessenden 8/4/2002) They are just two floors below the level where, minutes later, its collapse initiates. (Federal Emergency Management Agency 5/1/2002, pp. 2-34) Over radio, Palmer tells firefighter Joseph Leavey, “We’ve got two isolated pockets of fire. We should be able to knock it down with two lines.” (Dwyer and Flynn 2005, pp. 206) The fact that they reached so high up the tower only comes to light almost a year later, when a tape of radio communications from 9/11 is made public (see August 4, 2002). The New York Times will report “[N]owhere on the tape is there any indication that firefighters had the slightest indication that the tower had become unstable or that it could fall.” (Dwyer and Flynn 11/9/2002) Palmer’s communication appears to contradict claims that “extreme fires” contributed to the tower’s collapse. (Barter 9/13/2001; Lipton 10/20/2004) Ronald Bucca, a Special Forces veteran, had actually conducted his own private research into Islamic militancy following the 1993 WTC bombing. He’d even taken time, in 1996, to attend the beginning of the trial of Ramzi Yousef, a mastermind of the bombing (see September 5, 1996). (Lance 2003, pp. 180-183, 333-334)

(Langley 12/16/2001) There are still 3,520 planes in the air over the US.

Accounts will conflict over whether this aircraft is Flight 93 or Delta Air Lines Flight 1989, which is wrongly thought to have been hijacked. (Associated Press 8/30/2002; ABC News 9/11/2002; Bronner 8/1/2006; Spencer 2008, pp. 178) Delta 1989 was flying about 25 miles behind Flight 93 when air traffic controllers mistakenly suspected it might be hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001), and since then it has been instructed to land at Cleveland Hopkins Airport in Ohio (see (9:42 a.m.) September 11, 2001). (Adams, Levin, and Morrison 8/13/2002; Levin 9/11/2008) Flight 93 is currently flying east across Pennsylvania. (National Transportation Safety Board 2/19/2002 pdf file) NEADS has already tried getting fighter jets from a unit in Duluth, Minnesota, sent after Delta 1989, but the unit was unable to respond (see (Shortly After 9:41 a.m.) September 11, 2001). (9/11 Commission 1/22/2004 pdf file; 9/11 Commission 1/23/2004 pdf file)
NEADS Calls Selfridge Base - A NEADS weapons technician now calls the 127th Wing at Selfridge Air National Guard Base. He knows the unit has two F-16s in the air on a training mission. Although these jets are unarmed and only have a limited amount of fuel remaining, the commander at the Selfridge base agrees to turn them over to NEADS. (Spencer 2008, pp. 178) The commander says: “[H]ere’s what we can do. At a minimum, we can keep our guys airborne. I mean, they don’t have—they don’t have any guns or missiles or anything on board.” The NEADS technician replies, “It’s a presence, though.” (Bronner 8/1/2006)
Fighters May Have to Crash into Hijacked Plane - Military commanders realize that, without weapons, the Selfridge fighter pilots might have to slam their jets into a hijacked plane to stop it in its tracks. Colonel Robert Marr, the NEADS battle commander, will later reflect, “As a military man, there are times that you have to make sacrifices that you have to make.” (Raddatz 8/30/2002; ABC News 9/11/2002) However, the Selfridge jets never have to intercept either of the two suspect aircraft, and instead are able to head back to base. (Filson 2003, pp. 70; Carroll 9/2006 pdf file)
Selfridge Called due to Concerns about Delta 1989? - According to author Lynn Spencer, the NEADS weapons technician’s call to the Selfridge unit is made in response to a report NEADS received about the possible hijacking of Delta 1989 (see 9:39 a.m. September 11, 2001). (Spencer 2008, pp. 178) Vanity Fair magazine and the 9/11 Commission will also say NEADS calls the Selfridge unit in response to this report about Delta 1989. (9/11 Commission 7/24/2004, pp. 28; Bronner 8/1/2006)
NORAD Commander Gives Different Account - However, Larry Arnold, the commander of the Continental United States NORAD Region, will suggest the Selfridge unit is called due to concerns about both Delta 1989 and Flight 93. He will say: “We were concerned about Flight 93 and this Delta aircraft [Flight 1989] and were trying to find aircraft in the vicinity to help out. We didn’t know where it was going to go. We were concerned about Detroit… and the fighters up there were out of gas with no armament.” (Filson 2003, pp. 71)
NEADS Commander Claims Fighters Sent toward Flight 93 - Robert Marr will give another different account. He will claim that NEADS contacts the Selfridge base solely because of its concerns over Flight 93. He tells author Leslie Filson that before Flight 93 reversed course and headed back east (see (9:36 a.m.) September 11, 2001), NEADS thought it was “headed toward Detroit or Chicago. I’m thinking Chicago is the target and know that Selfridge Air National Guard Base has F-16s in the air.” NEADS contacts “them so they could head off 93 at the pass.” (Filson 2003, pp. 68) Marr will tell the 9/11 Commission that the Selfridge F-16s are going to be “too far from Cleveland to do any good,” and so he believes NEADS directs them to intercept Flight 93. (9/11 Commission 1/23/2004 pdf file) (Presumably, he means the jets cannot be responding to Delta 1989, which has been told to land in Cleveland (Levin 9/11/2008) )
9/11 Commission Disputes Arnold's and Marr's Accounts - The 9/11 Commission will reject Arnold’s and Marr’s accounts. It will state, “The record demonstrates, however, that… the military never saw Flight 93 at all” before it crashes, and conclude, “The Selfridge base was contacted by NEADS not regarding Flight 93, but in response to another commercial aircraft in the area that was reported hijacked (Delta Flight 1989, which ultimately was resolved as not hijacked).” (9/11 Commission 8/26/2004, pp. 101) Lt. Col. Doug Champagne, the pilot of one of the Selfridge F-16s, will recall that “he and his colleague never received orders to intercept [Flight 93] in any way.” (Casey 9/6/2006) Reports based on interviews with the two Selfridge pilots will make no mention of the jets being directed to intercept Delta 1989 either (see (9:56 a.m.-10:29 a.m.) September 11, 2001). (Filson 2003, pp. 68-70; Carroll 9/2006 pdf file; Casey 9/6/2006)

Members of New York Police Department’s elite Emergency Service Unit (ESU) are given an order that means they have to get out of the World Trade Center or delay entering it and consequently many of them will avoid being killed when the South Tower collapses, at 9:59 a.m. (Keegan and Davis 2006, pp. 101-102; Appel 2009, pp. 112-113) The ESU is a highly trained organization comprised of first response rescuers. (City of New York 6/29/2002) Its members respond to situations that require the most specialized training, such as hostage taking and water rescue, and use the most advanced equipment. (Keegan and Davis 2006, pp. 101)
Officers Are Ordered to Come Down from the WTC - Inspector Ronald Wasson, commanding officer of the ESU, earlier on divided his officers into four teams of five or six men and then sent two teams into each of the Twin Towers to assist the rescue operation. (McPhee and O'Shaughnessy 11/11/2001) But now, ESU commanders give the order for the unit’s members to “go tactical.” This means the officers in the towers have to come out of the buildings and go to the unit’s SWAT (special weapons and tactics) vans; put on their BDU (battle dress uniform) suits, flak jackets, and Kevlar helmets; and arm themselves with heavy weapons and assault rifles.
Commander Thinks Terrorists Might Attack the First Responders - The decision to order ESU officers to go tactical is made by Wasson, according to a book by Lieutenant William Keegan of the Port Authority Police Department. (Keegan and Davis 2006, pp. 101-102) Wasson is currently assembled with a number of other ESU officers outside the Twin Towers, at the corner of West and Vesey Streets. (Appel 2009, pp. 68) He decides that ESU officers should go tactical due to his concern that armed terrorists might attack the first responders at the WTC. He is “worried that with all his personnel inside the buildings, he [has] no way to protect the cops, firefighters, or civilians from the kind of low-intensity warfare—snipers, automatic weapons, car bombs, hostage situations—he [is] sure [will] follow the attack,” Keegan will write. He believes it is the responsibility of the New York Fire Department to deal with the fires in the Twin Towers, while the Police Department should be preparing for what might happen next. Many ESU members will come out of the towers after receiving the order to go tactical, according to Keegan. (Keegan and Davis 2006, pp. 101-102)
Order Is Given after an Officer Hears of the Pentagon Attack - However, according to author Anthea Appel, the order to go tactical is made by Sergeant Tom Sullivan, another ESU officer. Sullivan is currently at the corner of West and Vesey Streets along with Wasson, getting ready to take two teams into the WTC. At 9:56 a.m., after hearing over his radio about the attack on the Pentagon, which occurred at 9:37 a.m. (see 9:37 a.m. September 11, 2001), he exclaims, “Screw rescue!” He then pulls his men back and announces that all ESU teams will be “going in tactical,” according to Appel. “I want heavy vests, helmets, rifles, and machine guns,” he says. In response to his announcement, ESU officers start taking off their rescue gear and putting on combat gear. They take off their safety helmets and replace them with ballistic helmets. They take off their air tanks, unbuckle their Roco harnesses, and put on more body armor over their bulletproof vests. They also unlock their gun bins and take out shotguns, submachine guns, and assault rifles. Some officers grumble under their breath, annoyed at being held back. “They didn’t like wasting time fiddling around with equipment,” Appel will comment, “and this sudden switch interrupted their adrenaline momentum.” They will be in the middle of changing into their combat gear when the South Tower collapses (see 9:59 a.m. September 11, 2001). (Appel 2009, pp. 112-113)
Order Is Wrong but Saves Lives - The order to go tactical will turn out to be mistaken as there are no attacks by armed terrorists on the first responders at the WTC. However, as a result of it being issued, numerous ESU members will be outside the Twin Towers instead of inside the buildings when the South Tower comes down and many of them will therefore avoid being killed in the collapse. While 14 ESU members will die in the WTC collapses, a far greater number will survive, Keegan will write, “because Wasson’s order pulled them out of the towers and saved their lives.” (Keegan and Davis 2006, pp. 102) One ESU member, Detective Frank DeMasi, will conclude that Sullivan “definitely saved his life when he made that last-minute decision to switch from rescue to tactical mode,” according to Appel, since the delay while they changed into their combat gear “kept DeMasi and his teammates from walking into the South Tower before it collapsed.” (Appel 2009, pp. 265-266)

James Nieckarz.James Nieckarz. [Source: Maryknoll Mission Archives]Police officers order members of the public to get away from the World Trade Center, telling them the Twin Towers are in danger of collapsing. Shanthy Nambiar, a reporter for BridgeNews in New York, is standing on Vesey Street, beneath Building 7 of the WTC. She hears someone shout, “You guys shouldn’t be in this area.” She will later recall, “Police officers ordered people to start fleeing the area, saying the towers were in danger of collapse.” She runs north one block and then sees the South Tower coming down (see 9:59 a.m. September 11, 2001). (Casey 2001, pp. 156) Priest Father James Nieckarz is also standing outside Building 7 around this time. He will recall that a couple of police officers come along, shouting out to everyone on the street: “Everyone run to the north. The tower is shaking and may come down.” Nieckarz goes around Building 7 and then, as he is walking north, hears “a loud rumbling roar” behind him as the South Tower collapses. (Milisic 9/12/2001; United States Conference of Catholic Bishops 9/2003, pp. 15) Why the police officers encountered by Nambiar and Nieckarz believe the Twin Towers are in danger of collapsing is unclear. Although a New York City Police Department (NYPD) helicopter has reported “large pieces” falling from the South Tower (see (9:49 a.m.) September 11, 2001), the 9/11 Commission Report will state, “Prior to 9:59, no NYPD helicopter pilot predicted that either tower would collapse.” (9/11 Commission 7/24/2004, pp. 304)

The South Tower of the World Trade Center collapses.The South Tower of the World Trade Center collapses. [Source: Associated Press]The South Tower of the World Trade Center tilts to the southeast and then collapses. It was hit by Flight 175 at 9:03 a.m., 56 minutes earlier (see 9:03 a.m. September 11, 2001). (Washington Post 9/12/2001; New York Times 9/12/2001; MSNBC 9/22/2001; Cauchon 12/20/2001; Associated Press 8/21/2002; ABC News 9/11/2002; National Institute of Standards and Technology 9/2005, pp. 44) The first sign of the collapse is visible on floor 82. (National Institute of Standards and Technology 9/2005, pp. 87) The angle of the tilt will be disputed after 9/11 (see September-November 2005), as will the time it takes the towers to fall to the ground (see September 12, 2001-September 2005). (Ashley 10/9/2001; Eagar and Musso 12/2001; PBS Nova 5/2002; National Institute of Standards and Technology 8/30/2006)

Twenty minutes after the 9/11 attacks in New York (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001) and Washington (see 9:37 a.m. September 11, 2001), a bomb truck is stationed in downtown Oklahoma City, in preparation for any potential bombing related to the 1995 Oklahoma City bombing (see 8:35 a.m. - 9:02 a.m. April 19, 1995). Additionally, an Oklahoma County Sheriff’s Department command post is activated where convicted bombing conspirator Terry Nichols (see September 5, 2001) is being held. (The Oklahoman 4/2009)

George Piro.George Piro. [Source: FBI]George Piro and Ken Williams, two agents at the FBI field office in Phoenix, Arizona, visit a flight school in Phoenix to see if any suspicious students have attended it recently and the manager immediately informs them about Hani Hanjour, one of the alleged hijackers of Flight 77. As they watched the terrorist attacks unfolding on television, Piro and Williams decided they wanted to start responding to the crisis on their own initiative, rather than sitting around and waiting for an order. They know Phoenix has the second-highest concentration of flight schools in the nation. Piro therefore looked in the Yellow Pages and found three programs that offer commercial pilot licenses. With this information in hand, the two agents set out to visit some flight schools. The first one they go to is the Sawyer School of Aviation at Sky Harbor Airport in Phoenix. They ask the manager there if any suspicious students have attended recently. Almost without hesitation, she gives them the file of one such student: Hanjour. (Graff 2011, pp. 325; Graff 5/5/2011) Hanjour received training at the flight school earlier this year and, previously, in 1998 (see 1998 and Summer 2001). (Goldstein, Sun, and Lardner 10/15/2001; Berry 12/29/2001; 9/11 Commission 7/24/2004, pp. 529) He allegedly flew Flight 77 into the Pentagon (see 9:37 a.m. September 11, 2001). (Zimmerman 1/7/2016) Just after they are given the file, Piro receives a call on his cell phone from an agent from the FBI’s Boston office. The agent, who is currently at Logan International Airport in Boston, says he has a name from the passenger manifest for Flight 77 that the Phoenix agents should look into: Hani Hanjour. To the agent’s surprise, Piro replies, “I’m holding his file in my hands right now.” Piro and Williams then head back to their office to report their progress. At the office, Piro tells their squad leader, “I’ve identified one of the hijackers.” Incredulous at this news, the squad leader replies, “Get out of here—I don’t have time for jokes today.” (Graff 2011, pp. 325-326; Graff 5/5/2011)

Roger Cressey.Roger Cressey. [Source: Publicity photo]Roger Cressey, the deputy for counterterrorism on the National Security Council, suggests activating the Emergency Alert System (EAS) to address the nation, but no one with him knows what could be said to calm the public. (Graff 2017, pp. 341) Cressey is one of about a dozen people who remained in the White House Situation Room after most staffers evacuated from the White House (see (Shortly After 9:45 a.m.) September 11, 2001). (Clarke 2004, pp. 10; Gardham 9/10/2010) Apparently sometime shortly after Ralph Seigler, the Situation Room deputy director, reported that the Secret Service was saying a hostile aircraft was approaching Washington, DC (see (After 10:06 a.m.) September 11, 2001), Cressey proposes to his colleagues that they activate the EAS to give a message to the American public. However, Richard Clarke, the White House counterterrorism chief, promptly rejects his suggestion. “And have them say what?” Clarke asks. (Clarke 2004, pp. 9)
Alert System Is Not Used in Response to Today's Attacks - The EAS, known as the Emergency Broadcast System until the 1990s, was created in 1951 as part of America’s response to the threat of nuclear attack. It serves as a tool for the president and others to warn the American public about emergency situations. However, it is not activated at any point today in response to the terrorist attacks. Richard Rudman, chairman of the EAS National Advisory Committee, will later justify this, explaining that the EAS is intended to alert the public to the danger before an incident occurs, not afterward. “Some events really do serve as their own alerts and warnings,” he will comment. Referring to today’s attacks, he will say, “With the immediate live media coverage, the need for an EAS warning was lessened.” One broadcast engineer will say that activating the EAS after the first hijacked plane crashed into the World Trade Center (see 8:46 a.m. September 11, 2001) might have caused more harm than good. “At that point, it could have stirred up even more panic,” the engineer will say. (Stine 9/26/2001; Moore 8/13/2004, pp. 1 pdf file)

The military liaison at the FAA’s Cleveland Center calls NORAD’s Northeast Air Defense Sector (NEADS) and alerts it to the hijacked Flight 93. According to the 9/11 Commission, this is the first notification NEADS receives about Flight 93, but it comes too late, since the plane has already crashed (see (10:06 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 30; 9/11 Commission 8/26/2004, pp. 46)
'Bomb on Board' Flight 93 - At 10:05 a.m., the military liaison at the Cleveland Center, who is unaware that Flight 93 has just crashed, calls NEADS to inform it that Flight 93 is heading toward Washington, DC. Even though communicating with NEADS is not one of his responsibilities, he wants to make sure it is in the loop. (Spencer 2008, pp. 224) At NEADS, the call is answered by Tech Sergeant Shelley Watson. Shortly into the call, at 10:07, the military liaison tells her: “We got a United 93 out here. Are you aware of that?” He continues, “That has a bomb on board.” Watson asks: “A bomb on board? And this is confirmed? You have a mode three [beacon code], sir?” The military liaison replies, “No, we lost his transponder” (see (9:40 a.m.) September 11, 2001). The news about Flight 93 is shouted out to Major Kevin Nasypany, the NEADS mission crew commander. Nasypany responds: “Gimme the call sign. Gimme the whole nine yards.… Let’s get some info, real quick. They got a bomb?”
Liaison Wants Fighters Sent toward Flight 93 - The military liaison continues, asking Watson if NEADS scrambled fighter jets in response to Delta 1989, an aircraft that was mistakenly reported as having been hijacked (see (9:28 a.m.-9:33 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001). Watson replies: “We did. Out of Selfridge and Toledo” (see (9:55 a.m.) September 11, 2001 and 10:01 a.m. September 11, 2001), and says these jets are airborne. When the military liaison asks if the fighters can be directed to where Flight 93 is, Watson asks him if the Cleveland Center has latitude and longitude coordinates for this aircraft. The military liaison replies that he has not got this information available right now. All he knows is that Flight 93 has “got a confirmed bomb on board… and right now, his last known position was in the Westmoreland area.… Which is… in the Pittsburgh, Pennsylvania, area.” (North American Aerospace Defense Command 9/11/2001; Bronner 8/1/2006)
NEADS Searches on Radar - The news of a bomb on board Flight 93 spreads quickly at NEADS, and personnel there search for the aircraft’s primary return on their radar screens. But because the plane has already crashed, they will be unable to locate it. NEADS will only learn that Flight 93 has crashed at 10:15 a.m., during a call with the FAA’s Washington Center (see 10:15 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 30-31)
FAA Failed to Notify Military Earlier - The Cleveland Center’s notification to NEADS about Flight 93 comes 39 minutes after the plane was hijacked (see (9:28 a.m.) September 11, 2001) and 33 minutes after FAA headquarters was alerted to the hijacking (see 9:34 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 11, 28) At the time NEADS is alerted to Flight 93, NORAD is similarly uninformed about this aircraft, according to the 9/11 Commission. The Commission will state, “At 10:07, its representative on the air threat conference call stated that NORAD had ‘no indication of a hijack heading to DC at this time.’” According to the Commission, the National Military Command Center (NMCC) at the Pentagon learned about the Flight 93 hijacking slightly earlier on, at 10:03 a.m. (see 10:03 a.m. September 11, 2001). However, the NMCC was notified by the White House, not the FAA. (9/11 Commission 7/24/2004, pp. 42) A former senior FAA executive, speaking on condition of anonymity, will later try to explain why it takes the FAA so long to alert NEADS to Flight 93. He will say, “Our whole procedures prior to 9/11 were that you turned everything [regarding a hijacking] over to the FBI.” (Bronner 8/1/2006) Yet military instructions contradict this, stating, “In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA.” (US Department of Defense 7/31/1997 pdf file; US Department of Defense 6/1/2001 pdf file)
NORAD Commanders Claim Earlier Awareness of Flight 93 - Two senior NORAD officials will contradict the 9/11 Commission’s conclusion, and claim they were aware of Flight 93 well before it crashed (see Shortly Before 9:36 a.m. September 11, 2001 and (9:36 a.m.-10:06 a.m.) September 11, 2001). (Filson 2003, pp. 68, 71-73) Colonel Robert Marr, the NEADS battle commander, will tell the Commission that, while the flight was still airborne, “his focus was on UAL 93, which was circling over Chicago,” and he “distinctly remembers watching the flight UAL 93 come west, and turn over Cleveland.” (9/11 Commission 10/27/2003 pdf file; 9/11 Commission 1/23/2004 pdf file) Major General Larry Arnold, the commander of the Continental US NORAD Region, will recall, “[W]e watched the [Flight] 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward DC.” (Filson 2003, pp. 71)

Flight 93 crashed in the Pennsylvania countryside. Resue vehicles arrive in the distance.Flight 93 crashed in the Pennsylvania countryside. Resue vehicles arrive in the distance. [Source: Keith Srakocic/ Associated Press]Flight 93 crashes into an empty field just north of the Somerset County Airport, about 80 miles southeast of Pittsburgh, 124 miles or 15 minutes from Washington, D.C. Presumably, hijackers Ziad Jarrah, Ahmed Alhaznawi, Ahmed Alnami, Saeed Alghamdi, and all the plane’s passengers are killed instantly. (CNN 9/12/2001; North American Aerospace Defense Command 9/18/2001; Ellison 10/17/2001; Hillston 10/28/2001; Levin, Adams, and Morrison 8/12/2002; Associated Press 8/21/2002; MSNBC 9/3/2002) The point of impact is a reclaimed coal mine, known locally as the Diamond T Mine, that was reportedly abandoned in 1996. (Pittsburgh Tribune-Review 9/12/2001; Zapinski 9/12/2001; Frederick 9/11/2002) Being “reclaimed” means the earth had been excavated down to the coal seam, the coal removed, and then the earth replaced and planted over. (Kashurba 2002, pp. 121) A US Army authorized seismic study times the crash at five seconds after 10:06 a.m. (Kim and Baum 2002 pdf file; Perlman 12/9/2002) As mentioned previously, the timing of this crash is disputed and it may well occur at 10:03 a.m., 10:07 a.m., or 10:10 a.m.

The FAA’s Cleveland Center, which had the last contact with Flight 93 before it crashed, suggests that no distress signal indicating a plane crash has occurred was picked up at the time Flight 93 went down. (Federal Aviation Administration 9/11/2001; Federal Aviation Administration 9/11/2001) Flight 93 reportedly crashed in rural Pennsylvania at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001). (National Transportation Safety Board 2/19/2002 pdf file; 9/11 Commission 7/24/2004, pp. 30; Levin 9/11/2008) An air traffic controller at the Cleveland Center now says, apparently over an FAA teleconference, that someone has reported seeing black smoke in the vicinity of Flight 93’s last known position, near Johnstown, Pennsylvania. The controller then says, “We’re trying to see if we can get an ELT check.” (Federal Aviation Administration 9/11/2001; Federal Aviation Administration 9/11/2001) An “ELT” is an emergency locator transmitter, a device carried on most general aviation aircraft in the US that is designed to automatically start transmitting a distress signal if a plane should crash, so as to help search and rescue efforts in locating the downed aircraft. (Federal Aviation Administration 3/23/1990; Federal Aviation Administration 7/12/2001; Aircraft Owners and Pilots Association 1/22/2009) The Cleveland Center controller’s information, as an FAA timeline will later state, therefore indicates that “[n]o ELT” signal has been picked up in the area where Flight 93 apparently crashed “at this time.” (Federal Aviation Administration 9/11/2001) Someone at the FAA’s Command Center in Herndon, Virginia, acknowledges the controller’s communication, responding, “Copy that, Command Center.” (Federal Aviation Administration 9/11/2001) Whether anyone will subsequently report picking up an ELT signal in the area where Flight 93 apparently crashed is unclear. Major Allan Knox, who works at the Air Force Rescue Coordination Center, which is “the contact for credible” ELT signals, will tell the 9/11 Commission that he “does not recall an ELT detection being brought to his attention” today. (9/11 Commission 10/1/2003 pdf file; 9/11 Commission 10/6/2003 pdf file) However, an ELT signal was picked up in the New York area by the pilot of an aircraft minutes before Flight 11 crashed into the North Tower of the World Trade Center (see 8:44 a.m. September 11, 2001) and another ELT signal was picked up in the New York area by the same pilot minutes before Flight 175 crashed into the South Tower (see 8:58 a.m. September 11, 2001). (Federal Aviation Administration 9/11/2001 pdf file; New York Times 10/16/2001)

Ashleigh Adams, the first lady’s deputy press secretary, will later recall, “It felt like we were in a war, because the Secret Service was driving next to the motorcade and they were hanging out of the windows with their machine guns out.” She will add that she has “been around the agents” before, but has “never seen them with their guns.”
Motorcade Delayed by Traffic - However, the motorcade is slowed by the heavy traffic. Bush will describe, “Outside our convoy windows, the city streets were clogged with people evacuating their workplaces and trying to reach their own homes.” Rodriguez will say, “In the car, we seemed to be going in slow motion.” (National Journal 8/31/2002; Bush 2010, pp. 200) “The traffic was so bad that everything was stopped,” Andi Ball, Bush’s chief of staff, will recall. One of the Secret Service agents escorting Bush and her staff will later say a car sideswiped them during the journey.
Secure Location Is Secret Service Headquarters - The “secure location” that Bush and her staff are being taken to turns out to be the Secret Service headquarters. (Kessler 2006, pp. 136) The Secret Service headquarters, according to journalist and author Ronald Kessler, is “an anonymous nine-story tan brick building on H Street at Ninth Street NW in Washington.” (Kessler 2009, pp. 23) It is located a few blocks from the White House. After the Oklahoma City bombing in 1995 (see 8:35 a.m. - 9:02 a.m. April 19, 1995) it was reinforced to survive a large-scale blast. Bush and her entourage arrive there through an underground entrance. (Bamford 8/23/2009; Bush 2010, pp. 200-201)
Journey Reportedly Takes 45 Minutes - The exact time they arrive at is unclear. According to Washington Post reporter Bob Woodward, “In the traffic jam from the Capitol, it took 45 minutes to get [Bush] to Secret Service headquarters.” This would mean the first lady arrives there at around 10:55 a.m. (Woodward 2002, pp. 17) However, Bush will write that she watches the North Tower of the World Trade Center collapsing “live in front of my eyes,” on a screen at the headquarters. (Bush 2010, pp. 201) If this is correct, she must arrive at the headquarters sometime before 10:28 a.m., when the North Tower comes down (see 10:28 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 311) White House spokespeople will refuse to disclose where the first lady has been taken to, only saying she is at a “secure location.” (Associated Press 9/11/2001; McCaleb 9/12/2001; CNN 9/11/2002)

Someone from the 174th Fighter Wing, which is based at Hancock Field Air National Guard Base near Syracuse, NY, calls NORAD’s Northeast Air Defense Sector (NEADS) and speaks with Major Kevin Nasypany, the mission crew commander there. (North American Aerospace Defense Command 9/11/2001) Earlier on, shortly after seeing the second plane hitting the World Trade Center at 9:03, a commander of the 174th Fighter Wing called NEADS to offer fighter jets to help (see (After 9:03 a.m.) September 11, 2001). They’d said: “Give me ten [minutes] and I can give you hot guns. Give me 30 [minutes] and I’ll have heat-seeker [missiles]. Give me an hour and I can give you slammers.” (Scott 6/3/2002; Carey 9/12/2006) Yet, now, more than an hour after the second attack, these fighters have still not been launched. Syracuse tells Nasypany, “I’ve got guys that’ll be launching in about 15 minutes.” Despite the earlier promise to have heat-seekers and slammers on the planes, Syracuse says: “We’ve got hot guns. That’s all I’ve got.” Nasypany says: “I’ve got another possible aircraft with a bomb on board. It’s in Pennsylvania, York, approximate area.” He adds that there is “another one, that’s possibly at Cleveland area.” These aircraft, he says, are United Airlines Flight 93 and Delta ‘89, respectively. (Although Flight 93 has already crashed, NEADS apparently does not learn of this until 10:15 (see 10:15 a.m. September 11, 2001).) NEADS was alerted to Delta Flight 1989 at 9:41, and mistakenly suspects it has been hijacked (see 9:39 a.m. September 11, 2001). Syracuse says: “I’ve got two jets right now. Do you need more than two?” After NEADS requests another two, Syracuse replies, “Get four set up, yep.” (North American Aerospace Defense Command 9/11/2001) According to the Syracuse Post-Standard, the first fighters to launch from Hancock Field are two F-16s that take off at 10:42 a.m. A further three take off at about 1:30 p.m., and two more launch around 3:55 p.m. (see 10:42 a.m. September 11, 2001).

Dutchess County Airport.Dutchess County Airport. [Source: Phillip Capper]Tom White, a New York air traffic controller, incorrectly reports over an FAA teleconference that the first aircraft to hit the World Trade Center appears to have been a Sikorsky helicopter. (Federal Aviation Administration 9/11/2001; Federal Aviation Administration 1/2/2002; 9/11 Commission 5/21/2004) White is an operations manager at the FAA’s New York Terminal Radar Approach Control (TRACON) in Westbury, Long Island. (9/11 Commission 12/15/2003 pdf file) He says over the FAA teleconference that the Sikorsky helicopter had been heading south from Poughkeepsie, New York, and appeared to hit the WTC at 8:27 a.m. (see 8:27 a.m. September 11, 2001)—nearly 20 minutes before the first crash there actually took place (see 8:46 a.m. September 11, 2001).
TRACON Previously Said Small Plane Hit the WTC - About 20 minutes earlier, someone from the TRACON—presumably White—suggested over the teleconference that the first aircraft to hit the WTC was a small twin-engine plane. At around 9:55 a.m. they said: “I think we’ve identified the location of a departure point for aircraft number one [presumably a reference to the plane that hit the North Tower]. At approximately 12:03 Zulu time [i.e. 8:03 a.m. Eastern time], aircraft number one appears to have departed Poughkeepsie airport and established a southerly heading at a speed of about 160 knots [i.e. 184 miles per hour]. The profile looks like it might be a light twin.” Asked if they had any more information, the TRACON employee replied: “I tried to get in touch with Poughkeepsie tower. However, the phone lines are overloaded and the circuits are busy.” (Federal Aviation Administration 9/11/2001) The “Poughkeepsie airport” the helicopter took off from is presumably Dutchess County Airport. Sikorsky bases a fleet of its S-76 helicopters at Dutchess County Airport, which it dispatches to the New York metro areas as needed. (Venable 5/2000; Wagstaff 8/1/2003) Poughkeepsie is about 70 miles north of New York City. (Sherman 2/3/2008)
Radar Information Suggests Helicopter Hit WTC - White now gives an update over the FAA teleconference, and suggests the first aircraft to hit the WTC was in fact a helicopter. He says: “We tracked a Sikorsky helicopter… from Poughkeepsie to the Trade Center. It appeared to fly into the Trade Center at 12:27 [Zulu time, or 8:27 a.m. Eastern time]. That is preliminary information.” White then clarifies that this conclusion has been reached partly through replaying radar data. He says: “[T]he only target that we saw in the vicinity of the Trade Center at 12:27, to fly into the Trade Center, we, we played the radar and tracked it up through Westchester and Stewart. We had a departure off a Poughkeepsie at 12:03. The tower says the only thing they had southbound at that time was a Sikorsky helicopter, which is consistent with the speed that we followed it down.” (Federal Aviation Administration 9/11/2001; Federal Aviation Administration 9/11/2001)
Long Delay before False Information Is Corrected - The New York TRACON’s reports about a helicopter or small plane hitting the WTC are subsequently confirmed to be mistaken. However it apparently takes several hours before the erroneous information is corrected. David LaCates, the deputy operations manager at the FAA’s New York Center, will tell the 9/11 Commission that “he did hear rumors that the aircraft that struck the WTC was in fact a small airplane from Poughkeepsie,” and he “believes this rumor persisted for over an hour.” (9/11 Commission 10/2/2003 pdf file) According to one FAA chronology of this day’s events, it is only at 1:00 p.m. that the “Sikorsky helicopter” is “now believed not to have hit the WTC.” (Federal Aviation Administration 1/2/2002) Another FAA chronology will state that at 1:04 p.m. it is reported that the Sikorsky helicopter “landed 20 minutes early, normal GE run at 12:28Z [i.e. 8:28 a.m. Eastern time] to WTC.” (It is unclear what is meant by “normal GE run.”) (Federal Aviation Administration 9/11/2001)

An aircraft at Cleveland Hopkins International Airport.An aircraft at Cleveland Hopkins International Airport. [Source: Cleveland Plain Dealer]Delta Air Lines Flight 1989, a Boeing 767 out of Boston that is wrongly suspected of being hijacked (see 9:39 a.m. September 11, 2001 and (Shortly After 9:44 a.m.) September 11, 2001), lands at Cleveland Hopkins Airport in Ohio, and is directed to a remote area of the airport. (Federal Aviation Administration 9/16/2001; Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 7/24/2004, pp. 27-28; O'Mara 9/11/2006)
Plane Flies Long Path toward Airport - Delta Air Lines had been concerned about Flight 1989, and ordered it to land as soon as possible in Cleveland (see (9:42 a.m.) September 11, 2001). (Spencer 2008, pp. 167; Levin 9/11/2008) As it was heading in to land, air traffic controllers instructed Delta 1989 to follow a trajectory that initially took it far past Cleveland Airport. Unknown to the plane’s pilots, the controllers incorrectly believe the flight has been hijacked and contains a bomb, and they were therefore making time to evacuate the airport before the plane landed (see (9:50 a.m. and After) September 11, 2001). (Spencer 2008, pp. 191)
Plane Directed to Remote Area - Once Delta 1989 is on the ground, the Cleveland Terminal Radar Approach Control (TRACON) informs the FAA’s Cleveland Center that Delta 1989 is “on the ground at 1418,” where “1418” means 10:18 a.m. Cleveland Center asks, “Very safely too, I hope?” The TRACON responds that the plane is being taken to the bomb area to check. (Federal Aviation Administration 9/16/2001) Delta 1989 is directed to “taxi left onto taxiway Bravo and wait there.” This taxiway leads to a remote part of the airport that is far away from the terminal. The pilot does as instructed. (Spencer 2008, pp. 229)
Passengers Not Allowed Off - The pilots radio the airport’s air traffic control tower and say: “Just to make sure we don’t have any misunderstandings here, our flaps are up, we are landing only as a precaution at the company’s request. You understand that?” They ask if they are going to get to their gate soon, but the controller responds that city authorities are in charge and he believes people will be coming to search the aircraft. The controller advises that city authorities have said to keep the plane’s passengers on the aircraft for now. (Federal Aviation Administration 9/16/2001) The passengers and crew will have to remain on board for perhaps a couple of hours, until FBI agents allow them off (see 11:28 a.m.-12:23 p.m. September 11, 2001). (O'Mara 9/11/2006; Spencer 2008, pp. 270-271)
Conflicting Reports of Landing Time - Subsequent accounts will give conflicting times for when Delta 1989 lands at Cleveland Airport. According to a detailed timeline provided by the airport’s control tower, the aircraft is “on the ground” at 10:18 a.m. (Federal Aviation Administration 9/16/2001) Several accounts will give similar landing times of between 10:05 a.m. and 10:10 a.m. (Federal Aviation Administration 1/2/2002; Adams, Levin, and Morrison 8/13/2002) But a NORAD official will tell the 9/11 Commission that Delta 1989 landed at 9:47 a.m. (9/11 Commission 5/23/2003) Other accounts will say it lands at between 10:33 a.m. and 10:45 a.m. (Singer 9/11/2001; Singer 9/11/2001; Federal Aviation Administration 9/17/2001 pdf file)

Damage to the southwest corner of WTC 7.Damage to the southwest corner of WTC 7. [Source: Arquelio Galarza]World Trade Center Building 7 (WTC 7) suffers some damage, caused by debris from the collapse of the north WTC tower, according to later official reports. (Federal Emergency Management Agency 5/1/2002, pp. 5-16; National Institute of Standards and Technology 11/2008, pp. 16)
WTC 7 Undamaged by South Tower Collapse - WTC 7 is a 47-story office building located 370 feet north of the North Tower (WTC 1). In the final report of its investigation into WTC 7’s collapse, published in November 2008 (see November 20, 2008), the National Institute of Standards and Technology (NIST) will state that although a few windows on the lower floors of WTC 7’s south face were broken when the South Tower (WTC 2) collapsed at 9:59 a.m. (see 9:59 a.m. September 11, 2001), “None of the large pieces of debris from WTC 2 hit WTC 7, because of the large distance between the two buildings,” and there is “no evidence of structural damage to WTC 7” as a result of the South Tower’s collapse.
Debris Reportedly Damages Exterior Columns - However, when the North Tower collapses (see 10:28 a.m. September 11, 2001), some fragments of debris are “forcibly ejected” from it, and travel “distances up to hundreds of meters.” According to NIST, pieces of this debris “hit WTC 7, severing six columns on floors 7 through 17 on the south face and one column on the west face near the southwest corner.” NIST will add that the debris also causes “structural damage between floor 44 and the roof,” and breaks a large number of windows on WTC 7’s south face.
Building Core Undamaged - However, NIST will state, based on “photographic evidence, witness accounts, and engineering judgment, it is likely that the structural damage (steel and floor slabs) did not penetrate beyond the perimeter of the building core. At the southwest corner, the structural damage extended only about one-third of the distance from the exterior wall to the building core.” NIST will comment, “Compared to the airplane impact damage to the WTC towers, there was relatively little damage to the interior of WTC 7.” There is also “no superficial or structural damage” to WTC 7’s north and east faces. And the sprayed fire resistive material that has been applied to the building’s steel columns, girders, and beams is only damaged in the “immediate vicinity of the WTC 1 debris impact.” NIST will admit, however, that there are “uncertainties” in its accounting of the events leading up to the collapse of WTC 7, because “the remains of all the WTC buildings were disposed of before Congressional action and funding was available for [its] investigation [of the WTC collapses] to begin” (see Shortly After September 11, 2001 and September 12-October 2001). (National Institute of Standards and Technology 8/21/2008; National Institute of Standards and Technology 11/2008, pp. 15-16)
FEMA Describes WTC 7 Damage - According to an earlier report on the collapse of WTC 7, published by the Federal Emergency Management Agency (FEMA) in May 2002 (see May 1, 2002), at that time, the “extent and severity of the resulting damage to WTC 7” when the North Tower collapses “are currently unknown.” But based on “photographic evidence and eyewitness accounts,” it is “assumed that the south side of the building was damaged to some degree.” FEMA’s report will state: “It does not appear that the collapse of WTC 1 affected the roof, or the east, west, and north elevations of WTC 7 in any significant way. However, there was damage to the southwest corner of WTC 7 at approximately floors 8 to 20, 24, 25, and 39 to 46.” The report will add: “According to firefighters’ eyewitness accounts from outside of the building, approximately floors 8-18 were damaged to some degree. Other eyewitness accounts relate that there was additional damage to the south elevation.” (Federal Emergency Management Agency 5/1/2002, pp. 5-16, 5-20)
Structural Damage Not Responsible for Collapse - WTC 7 will collapse at 5:20 p.m. this afternoon (see (5:20 p.m.) September 11, 2001). (National Institute of Standards and Technology 8/21/2008) However, NIST will conclude that the structural damage the building suffers plays no role in causing it to come down. NIST will state, “Other than initiating the fires in WTC 7, the damage from the debris from WTC 1 had little effect on initiating the collapse of WTC 7.” (National Institute of Standards and Technology 11/2008, pp. xxxvii) WTC 7 suffers fires on some floors, which are reportedly initiated by debris from the collapse of the North Tower (see (10:28 a.m.-5:20 p.m.) September 11, 2001). According to NIST, it is these fires, “rather than the structural damage that resulted from the impacts” of debris, which “initiated the building’s collapse.” (National Institute of Standards and Technology 8/21/2008)

FBI agents in New York quickly set up a temporary field office in an FBI parking garage, where they will be based for the next few weeks, after the attacks on the World Trade Center rendered their original office unusable. The New York office is the FBI’s largest field office, comprising some 1,100 special agents. It is located at 26 Federal Plaza, just a few blocks away from the WTC site. However, the collapses of the Twin Towers (see 9:59 a.m. September 11, 2001 and 10:28 a.m. September 11, 2001) disabled its telephone service, thereby rendering it useless. Officials are also concerned that 26 Federal Plaza might be the target of another terrorist attack.
New Facility Is Set Up in 24 Hours - Therefore, “Almost immediately” after the Twin Towers came down, according to the New York Times, the FBI starts relocating to a garage in Manhattan. The block-long, multilevel garage at 26th Street and the West Side Highway is usually used by the FBI to store and repair its fleet of vehicles. But within 24 hours of the attacks on the WTC, a temporary field office is up and running there. The facility is equipped with about 100 laptop computers. Three hundred phone lines are installed, with phones hooked up to a satellite truck positioned outside the garage.
Investigation Is Coordinated from the Temporary Facility - Officials from over two dozen federal, state, and local agencies are then based at the makeshift facility. Barry Mawn, director of the FBI’s New York office, and key federal prosecutors, including Mary Jo White, US Attorney for the Southern District of New York, coordinate the work of almost 2,000 investigators from there. The garage will serve as the command center for the first four weeks of the FBI’s investigation of the terrorist attacks. (Rashbaum 9/24/2001; Thompson 10/20/2001; Kessler 2002, pp. 5, 424; Garcia 3/2002 pdf file) It will be “New York’s nerve center for information about the attacks,” according to the Associated Press. (Associated Press 9/27/2001) Agents will move back to their original field office at 26 Federal Plaza early in October. (Thompson 10/20/2001)

Brigadier General Montague Winfield finally returns to his post as the deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon, after leaving a colleague, who only recently qualified to take over the position, to stand in for him throughout the terrorist attacks. (9/11 Commission 4/29/2004 pdf file; 9/11 Commission 6/17/2004) At 8:30 a.m. Winfield left his post to attend a pre-scheduled meeting that was unrelated to the morning’s attacks and had been convened by the Air Force. Since that time, Captain Charles Leidig has replaced him as the DDO (see 8:30 a.m. September 11, 2001). Leidig, the deputy for Command Center operations, only qualified to stand in as the DDO in the NMCC about a month ago. Even though officers in the NMCC realized the US was under terrorist attack when the second plane hit the World Trade Center at 9:03 a.m., Winfield did not return to his post at that time (see (Shortly After 9:03 a.m.) September 11, 2001). (9/11 Commission 7/21/2003 pdf file; 9/11 Commission 4/29/2004 pdf file; 9/11 Commission 6/17/2004 pdf file)
Winfield Returns to His Post, but Timing Unclear - Now Winfield finally relieves Leidig and resumes his duties as DDO. This happens after Flight 93 has crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001), although the exact time is unclear. In a private interview with the 9/11 Commission, Leidig will say he is “certain that Winfield returned [from the meeting] after the Pentagon was hit” at 9:37 a.m. (see 9:37 a.m. September 11, 2001), but he “is not certain of Winfield’s arrival in relationship with the vice chairman” of the Joint Chiefs of Staff, General Richard Myers. (9/11 Commission 4/29/2004 pdf file) (According to the 9/11 Commission Report, Myers arrived at the NMCC shortly before 10:00 a.m. (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 38) ) Winfield then takes over as DDO “at some point in relation to the report of the Pennsylvania crash,” according to Leidig. As the 9/11 Commission will point out, since the crash of Flight 93 happened around 10:03 a.m., “any reporting would be after that time.” (9/11 Commission 4/29/2004 pdf file) During a public hearing of the 9/11 Commission, Leidig will similarly say that Winfield takes over from him “[r]ight after we resolved what was going on with United 93.” He will also say that a report over the NMCC’s air threat conference at 10:37 a.m., about an anonymous threat against Air Force One (see (10:32 a.m.) September 11, 2001), occurs “right after I was relieved on the watch by General Winfield.” (9/11 Commission 6/17/2004) This would indicate that Winfield takes over from Leidig at around 10:30 a.m.
Unclear If Winfield Returns to Post Immediately after Meeting - It is also unclear whether Winfield returns to his position as DDO immediately after leaving the Air Force-convened meeting, or he allowed Leidig to continue in his place even while he was available to resume his duties. A 9/11 Commission memorandum will state, “Winfield transitioned into the position [of DDO] upon his return to the NMCC,” following the meeting. (9/11 Commission 7/21/2003 pdf file) Leidig will recall that he “looked up at one point and General Winfield was standing next to him.” He will also recall that Myers “looked at him at one time and realized the coordinator [i.e. the DDO] was not a general as the position called for, and asked who the general or admiral was that had duty that day.” The guidance that was subsequently given was “to get General Winfield briefed up and in the chair.”
Leidig Listens to Conference before Returning to Post - After Winfield returns to his position as DDO, Leidig initially “stands next to him and listens to the [NMCC’s air threat] conference.” Leidig will then transition into his regular job, which involves making sure the NMCC operates properly, and start dealing with the smoke coming into the center and other issues effecting operations there. (9/11 Commission 4/29/2004 pdf file)

Secretary of the Army Thomas White is ordered to leave the Pentagon and go to Site R, an alternate military command center outside Washington, DC, but the decision to send him there will subsequently be found to have been a mistake and so he will return to the Pentagon later in the day. (Chiarelli 2/5/2002; Christopher N. Koontz 2011, pp. 57 pdf file; Arkin 2013, pp. 176) White arrived at the Army Operations Center (AOC) in the basement of the Pentagon sometime after 9:37 a.m., when the Pentagon was attacked (see 9:43 a.m. September 11, 2001). (Chiarelli 2/5/2002; White 10/26/2004; Goldberg et al. 2007, pp. 135) While there, he has provided leadership and guidance to personnel in the center. (Christopher N. Koontz 2011, pp. 56 pdf file)
Army Secretary Is Ordered to Leave the Pentagon - After he has spent some time in the AOC, though, he is ordered to leave the Pentagon and go to Site R, a secure complex of buildings on the Pennsylvania-Maryland border. (Goldberg et al. 2007, pp. 135; Arkin 2013, pp. 176) The facility was designed as a duplicate of the Pentagon’s National Military Command Center (NMCC) that would serve as the Pentagon’s primary command center if the NMCC was destroyed in an attack or needed to be evacuated. (Creed and Newman 2008, pp. 174) White is ordered to go there by Major General Peter Chiarelli, the Army’s director of operations, readiness, and mobilization. Chiarelli will later recall that he issued the order to White after he “got word that we were going to exercise a relocation plan of key leaders to a place called Site R.”
White Initially Objects to Leaving the Pentagon - White is unhappy when he is first told that he has to leave the Pentagon and refuses to go. “He communicated he was not leaving, he was staying in the building,” Chiarelli will recall. But the officer in charge of the relocation and continuity of operations plan then explains to Chiarelli that White has to go to Site R. He says: “Sir, he has no choice at this time. This has been directed and he must immediately proceed to leave here. This is bigger than him. This is continuity of the government of the United States.” Chiarelli asks the officer, “Are you sure of this?” and the officer replies: “Yes, I’m sure. Sir, you need to go up and tell him he needs to get up and go.” Chiarelli therefore goes up to White and tells him that he has “no choice; he was bound to do this; we had gotten word that this portion of the implementation plan was in effect, and that he must proceed directly to a specified place in the building where he would get in a helicopter and leave.” White then agrees to go to Site R.
Order to Send White Away Will Be Found to Be Unnecessary - He leaves the Pentagon at the same time as Deputy Secretary of Defense Paul Wolfowitz does (see (11:00 a.m.) September 11, 2001) and the two men are flown to the secure facility in the same helicopter, according to Chiarelli. However, personnel in the AOC will subsequently discover that the decision to send White to Site R was a mistake. “We found out that it wasn’t required for him to leave at that particular point in time, because the level of evacuation did not reach his level,” Chiarelli will say. The unnecessary order came about because the person who said White had to leave the Pentagon “misspoke over the phone,” he will add. White will therefore return to the Pentagon about four hours after leaving it. (Chiarelli 2/5/2002)
Army Vice Chief of Staff Will Be in Charge While White Is Away - As secretary of the Army, White is the top civilian leader for the US Army and is responsible for the effective and efficient functioning of the Army. (US Department of the Army 7/9/2002 pdf file; Collins 4/7/2017) He is also the “top executive agent in the Pentagon hierarchy,” the “coordinator of continuity for the Pentagon,” and the “middleman for military support to civil authorities,” according to military expert and author William Arkin. But while he is away from the Pentagon, General John Keane, vice chief of staff of the Army, will be “in charge of the Army (and of decisions relating to military support to civil authorities),” Arkin will write. (Arkin 2013, pp. 176)

[Source: Greg Schaler / FEMA]Joseph Allbaugh, the director of the Federal Emergency Management Agency (FEMA), is flown back to Washington, DC, after leaving a major conference he has been attending in Montana. (DeMers 10/2001 pdf file; CNN 10/4/2001; Borgstrom 10/25/2001) Allbaugh was one of hundreds of emergency management officials from around the US attending the annual conference of the National Emergency Management Association (NEMA) in Big Sky, Montana, which began on September 8 and was originally scheduled to continue until September 12 (see September 8-11, 2001). He was the keynote speaker at the conference, and in his speech the previous day, September 10, talked about his focus on improving capabilities and preparing for disaster.

Allbaugh Sees Second Attack on TV - Allbaugh will later recall that on this morning, he “turned on CNN” and “actually saw the second plane hit the tower.” He will comment, “I thought it was a movie clip,” but then “reality started sinking in.” When he learned that the plane was the second to have hit the World Trade Center, he knew “immediately it was terrorism.” (CNN 10/4/2001) Allbaugh went into the meeting he was due to attend and announced: “You all will have to excuse me. I have more pressing matters.” (Fournier 9/8/2002) He was then one of the first to leave the NEMA conference. (Janofsky 9/12/2001)
Conflicting Accounts of Flight - Allbaugh is subsequently flown back to Washington, although there are conflicting accounts of his journey. Allbaugh will later recall that after leaving the conference, he moved on to the city of Bozeman, Montana, and then “waited a couple of hours for a plane.” Finally, he will say, a KC-135 military tanker plane flies him back to the capital. (CNN 10/4/2001) According to another account, Major Rick Gibney, a pilot with the 119th Fighter Wing of the North Dakota Air National Guard, was originally tasked with flying Allbaugh home in his F-16 fighter jet, but, instead, an Air Force C-17 cargo plane is diverted to transport the FEMA director back to Washington. (Borgstrom 10/25/2001) But the Gainesville Sun will report that Allbaugh initially headed out from the conference with Craig Fugate, the director of Florida’s Division of Emergency Management. Fugate rented a car to drive back to Florida and Allbaugh joined him as a passenger. Allbaugh was then dropped off in Missouri, from where he is flown back to Washington. (Arndorfer 10/22/2005) Other emergency management officials that were at the NEMA conference are also flown home on military aircraft throughout the day (see (After 11:00 a.m.) September 11, 2001 and (After 4:30 p.m.) September 11, 2001). (Nagy 9/13/2001; DeMers 10/2001 pdf file; Murphy 10/11/2001)
Allbaugh Joins President and Others at the White House - Allbaugh will recall that his flight to Washington takes four and a half hours. After arriving back in the capital, he heads directly to the White House, where he spends the evening with the president, vice president, and many others. (CNN 10/4/2001) It is unclear when exactly Allbaugh arrives in Washington, though he will be at the White House by 7:15 p.m., when he gives a press briefing. (White House 9/11/2001)
Allbaugh in Charge of Responding to Domestic Terrorist Attacks - In May this year, President Bush put Allbaugh, as FEMA director, in charge of “consequence management” in response to any terrorist attacks in the United States. Allbaugh was charged with creating an Office of National Preparedness to coordinate the government’s response to any such attack (see May 8, 2001). (White House 5/8/2001; Gerstenzang 5/9/2001) FEMA plays an important part in the government’s response to the attacks in New York and Washington on this day. It puts its “federal response plan” into effect, which involves coordinating with 28 other federal agencies and the American Red Cross; it dispatches eight urban search and rescue teams to New York to search for victims in the rubble of the WTC; and it has four urban search and rescue teams sifting through the remains of the crash at the Pentagon. (Ballard and Lunney 9/11/2001; White House 9/11/2001)

United Airlines issues a press release confirming that Flight 93 has crashed. Flight 93 went down in Pennsylvania shortly after 10:00 a.m. (see (10:06 a.m.) September 11, 2001). The release states: “United Airlines has confirmed one of its flights has crashed near Pittsburgh, Pennsylvania. United Flight 93, a Boeing 757 aircraft, is the flight number involved. The flight originated in Newark and was bound for San Francisco.” The release adds, “United is deeply concerned about a further flight, United Flight 175, a Boeing 767, which was bound from Boston to Los Angeles.” (United Airlines 9/11/2001) Although Flight 175 hit the World Trade Center at 9:03 (see 9:03 a.m. September 11, 2001), United Airlines will not publicly confirm it has crashed until 11:53 a.m. (see 11:53 a.m. September 11, 2001).

American Airlines issues a statement confirming that it has lost two of its aircraft in “tragic incidents this morning.” The statement identifies the aircraft as “Flight 11, a Boeing 767 en route from Boston to Los Angeles,” and “Flight 77, a Boeing 757 operating from Washington Dulles to Los Angeles.” The statement adds, “Because of the heightened security due to the nature of today’s events, American said it is working closely with US government authorities and will not release more information at this time.” (Associated Press 2001 pdf file; Associated Press 9/11/2001; CNN 9/12/2001) Flight 11 hit the North Tower of the World Trade Center at 8:46 a.m. (see 8:46 a.m. September 11, 2001) and Flight 77 hit the Pentagon at 9:37 a.m. (see 9:37 a.m. September 11, 2001). (9/11 Commission 6/17/2004)

At around 8:00 p.m., Afghanistan time (11:30 a.m., New York time), Taliban leader Mullah Omar allegedly says, “Things have gone much further than expected.” This is according to what the New Yorker will describe as “Afghan intelligence sources” who monitor the call. (It is unclear what “Afghan intelligence sources” means, since the Taliban control nearly all of Afghanistan at this time, but it could be a reference to Northern Alliance forces; the CIA gave them equipment to monitor the Taliban (see Winter 1999-March 2000).) Omar’s comment takes place over an hour after one of the World Trade Center towers collapsed, which means thousands have been killed in the attacks, not hundreds (see 9:59 a.m. September 11, 2001). An Afghan intelligence official will later say: “They were expecting a reaction. But they thought it would be a Clinton-type reaction. They didn’t anticipate the kind of revenge that occurred.” (Anderson 6/10/2002) The “Clinton-type reaction” presumably is a reference to the August 1998 missile strikes on Sudan and Afghanistan during the Clinton administration (see August 20, 1998).

Air Force One at Barksdale Air Force Base.Air Force One at Barksdale Air Force Base. [Source: Win McNamee / Reuters]Air Force One, with President Bush on board, lands at Barksdale Air Force Base—the home of the B-52 bomber—near Shreveport, Louisiana. (Sanger and van Natta 9/16/2001; Langley 12/16/2001; BBC 9/1/2002) The president’s plane was escorted by fighter jets from the 147th Fighter Wing of the Texas Air National Guard as it came in to land (see (11:29 a.m.) September 11, 2001). (Gibbs 9/14/2001; Filson 2003, pp. 87; Bush 2010, pp. 132) Two of those fighters now land at Barksdale with Air Force One while the other two remain airborne, flying a combat air patrol over Shreveport and Bossier City. Aircraft and personnel at Barksdale were participating in the major training exercise Global Guardian this morning, before the terrorist attacks began (see 8:48 a.m. September 11, 2001), and after touching down, Air Force One taxies past 40 fully loaded B-52s. (Villafuerte 9/8/2002; Bombardier 9/8/2006 pdf file; Draper 2007, pp. 141) Air Force personnel dressed in full combat gear and brandishing M-16s then set up a perimeter around the plane. (Gibbs 9/14/2001) Bush initially remains on board, gathering more intelligence. There is no mobile gangway on the tarmac and so he is unable to get off through his usual door in the top half of Air Force One. Instead, the flight crew opens a hatch near the belly of the plane and lowers a set of retractable stairs while Bush continues working the phones. The president finally gets off the plane just before noon and is then escorted away from it amid tight security (see (11:55 a.m.) September 11, 2001). (Sammon 2002, pp. 111-112) The Daily Telegraph will later comment, “The official reason for landing at Barksdale was that Mr. Bush felt it necessary to make a further statement (see 12:36 p.m. September 11, 2001), but it isn’t unreasonable to assume that—as there was no agreement as to what the president’s movements should be—it was felt he might as well be on the ground as in the air.” (Langley 12/16/2001) Bush will remain at Barksdale Air Force Base for almost two hours before taking off again on Air Force One (see 1:37 p.m. September 11, 2001). (Tapper 9/12/2001; 2d Bomb Wing 6/30/2002 pdf file)

United Airlines finally issues a press release confirming that Flight 175 has crashed, nearly three hours after this aircraft hit the World Trade Center (see 9:03 a.m. September 11, 2001). The release states, “United Airlines has now confirmed that two of its aircraft have crashed.” These include “United Flight 175, a Boeing 767 aircraft, [that] departed from Boston at 7:58 a.m. local time, bound for Los Angeles, with 56 passengers onboard, two pilots and seven flight attendants.” (United Airlines 9/11/2001) United Airlines previously issued a press release, at 11:17, confirming the crash of Flight 93 (see 11:17 a.m. September 11, 2001), but this had stated that the airline was, at that time, only “deeply concerned” about Flight 175. (United Airlines 9/11/2001) However, at 9:22, the United Airlines System Operations Control manager had issued an advisory to all the airline’s facilities, stating that Flight 175 had been in an accident in New York (see 9:22 a.m. September 11, 2001). (9/11 Commission 8/26/2004, pp. 26) And Colin Scoggins, the military liaison at the FAA’s Boston Center, will later claim that United confirmed to the center that Flight 175 was down, “within two or three minutes” (see (9:06 a.m.) September 11, 2001). (Bronner 8/1/2006)

The Federal Aviation Administration (FAA) sends a fax to the White House Situation Room, giving positive identification of the four hijacked aircraft involved in the morning’s attacks. However, two of the four flight numbers it provides are wrong. (Draper 2007, pp. 143) Yet, by late morning, American Airlines and United Airlines had already issued press releases confirming that the four planes that crashed were flights 11, 175, 77, and 93 (see 11:17 a.m. September 11, 2001, (11:18 a.m.) September 11, 2001, and 11:53 a.m. September 11, 2001). (Associated Press 9/11/2001; United Airlines 9/11/2001; United Airlines 9/11/2001) Journalist and author Robert Draper will later comment that, while there is much heroism on September 11, the FAA’s erroneous fax is an example of how the day is also “marred by appalling haplessness.” (Draper 2007, pp. 143)

Barry Jennings, a City Housing Authority worker who had become trapped in World Trade Center Building 7, finds the building’s lobby in ruins as he is being rescued from it, and steps over what feels to him like dead bodies. (Dylan Avery 2007) After the first plane hit the WTC, Jennings had gone up to the emergency command center on the 23rd floor of WTC 7 along with Michael Hess, New York’s corporation counsel (see (Shortly Before 9:03 a.m.) September 11, 2001). (Associated Press 9/11/2001; Dylan Avery 2007) After heading down the stairs, the two men became trapped on the building’s eighth floor (see (Between 9:15 a.m. and 12:00 p.m.) September 11, 2001). Some time later, firefighters come into WTC 7 to help the two men out of the building. (UPN 9 9/11/2001; National Institute of Standards and Technology 9/2005, pp. 109-110)
Lobby Is 'Total Ruins' - According to Jennings, when he gets down to the lobby, he is astonished to find it totally ruined. In a 2007 interview he will recall: “[W]hen I came in there, the lobby had nice escalators. It was a huge lobby.” But reaching it again, he asks the firefighter who is escorting him, “Where are we?” and the firefighter answers, “This was the lobby.” Jennings finds this “unbelievable,” and says, “You gotta be kidding me.” He will describe the lobby as being “total ruins.”
'Stepping over People' - Furthermore, Jennings steps over what may be dead bodies in the lobby. He will say: “[T]he firefighter that took us down kept saying, ‘Do not look down,’ and I kept saying, ‘Why is that?’ [He said,] ‘Do not look down.’ And, stepping over people. And you know you could feel when you’re stepping over people.” (Dylan Avery 2007) Yet most people were evacuated from WTC 7 around 9:03 a.m., if not earlier (see (9:03 a.m.) September 11, 2001). (National Institute of Standards and Technology 9/2005, pp. 109) The very latest that people left the building, according to official accounts, was 9:30 a.m. (see (9:30 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 305) In a later interview, Jennings will clarify: “I never saw dead bodies.… [I]t felt like I was stepping over them but I never saw them.” The BBC will say, “There is no evidence that anyone died in Tower 7 on 9/11.” (BBC 7/4/2008; BBC 7/6/2008) According to the National Institute of Standards and Technology (NIST), firefighters lead Jennings and Hess out of WTC 7 at around 12:10 p.m. to 12:15 p.m. (see 12:10 p.m.-12:15 p.m. September 11, 2001). (National Institute of Standards and Technology 6/2004, pp. L-18)

The FBI arrives at Washington’s Dulles International Airport and begins its investigation of the hijacking of Flight 77, which departed from the airport this morning. (9/11 Commission 9/29/2003 pdf file; Goldberg et al. 2007, pp. 161) Flight 77 took off from Dulles Airport at 8:20 a.m. (see (8:20 a.m.) September 11, 2001) and crashed into the Pentagon at 9:37 a.m. (see 9:37 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 8, 10) The FBI’s Washington Field Office (WFO) was reportedly notified of the hijacking of Flight 77 at around 9:20 a.m. (see (9:20 a.m.) September 11, 2001). (US Department of Health and Human Services 7/2002, pp. C-45 pdf file) Dulles Airport has now been locked down, preventing people from entering or leaving it, and the terminals have been evacuated (see (Between 9:38 a.m. and 11:37 a.m.) September 11, 2001). (9/11 Commission 10/16/2003 pdf file; Trento and Trento 2006, pp. 36; Priska Neely 10/21/2010)
Fifty FBI Agents Arrive at Dulles Airport - The FBI is responsible for investigating the hijacking of Flight 77, and so Special Agent in Charge Arthur Eberhart has sent a team of 50 agents to the airport to look into it and provide additional security to prevent another hijacking. (US Department of Health and Human Services 7/2002, pp. A-23, C-45 pdf file) However, the agents only arrive there at around 12:40 p.m., according to a 9/11 Commission memorandum. (9/11 Commission 9/29/2003 pdf file) The first thing they do there is seize the security tape at the main terminal’s west checkpoint, according to Ed Nelson, a security manager at the airport. (Trento and Trento 2006, pp. 36) They also interview ticket agents, security personnel, baggage and food handlers, and other personnel, and collect evidence. (Eberhart 1/15/2002; Goldberg et al. 2007, pp. 161) They order the confiscation of the 52 computer hard drives that record all electronic television and security information at the airport. The hard drives contain all of the video recorded by the airport’s surveillance cameras and all records of electronic badges used to gain access to secure areas. (Trento and Trento 2006, pp. 34)
Agents Assess the Passengers on Grounded Planes - Airport officials have received no guidance regarding how passengers on planes that have been grounded in response to the terrorist attacks this morning should be processed. But the FBI agents at the airport now take the lead in reviewing the passengers who have deboarded from planes. (9/11 Commission 9/29/2003 pdf file) The FBI will set up a command post and a substantial operation at Dulles Airport to carry out its investigation of the hijacking of Flight 77. Van Harp, head of the WFO, will assume responsibility for its response at the airport. (Harp 12/12/2001)

Federal agents ask managers Steve Wragg and Ed Cox to help identify the screeners who worked at the checkpoint at Washington’s Dulles International Airport that the alleged hijackers of Flight 77 passed through this morning, and suggest these screeners could be guilty of collusion with the hijackers. (Trento and Trento 2006, pp. 129) Flight 77 took off from Dulles Airport at 8:20 a.m. (see (8:20 a.m.) September 11, 2001) and crashed into the Pentagon at 9:37 a.m. (see 9:37 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 8, 10) Wragg works as the district manager in charge of the airport for Argenbright Security, which handles the passenger security checkpoints, baggage, and other services there for American Airlines and United Airlines. (Atlanta Business Chronicle 10/12/2001; Trento and Trento 2006, pp. 125) Cox is the airport security coordinator at Dulles Airport. (9/11 Commission 10/16/2003 pdf file) Wragg was away from work when the crashes at the World Trade Center took place but promptly headed to Dulles Airport when he learned of them (see After 11:00 a.m. September 11, 2001). (Trento and Trento 2006, pp. 128) Cox, meanwhile, was at work in the airport operations office when they occurred. (9/11 Commission 10/16/2003 pdf file)
Agents Say They Are 'Looking for Collusion' - At some point this afternoon, CIA and FBI agents who have come to the airport to look into the hijacking of Flight 77 ask the two men to help identify the screeners who were working at a security checkpoint at the airport when the hijackers passed through it. The agents apparently believe that some of the screeners may be complicit in this morning’s attacks. “We want you to identify the screeners and quite frankly we’re looking for collusion here,” they say. They show Wragg and Cox video on which the alleged hijackers can be seen passing through the checkpoint (see 7:18 a.m. September 11, 2001, 7:35 a.m. September 11, 2001, and 7:36 a.m. September 11, 2001). (It is unclear whether Wragg and Cox are shown footage of all the hijackers going through the checkpoint or just some of them.)
Agents Seem Desperate to Find Incriminating Evidence - Wragg gets the impression that the federal agents are desperate to find something incriminating on the video. As one of the hijackers is shown walking through a metal detector, an agent asks, “Is he looking at your agent there?” Presumably referring to hijacker Nawaf Alhazmi, an FBI agent asks: “Can you zoom in on that guy’s back pocket? Zoom in. Is that a box cutter? Zoom in on that.” Wragg just laughs at this, which strikes him as “absolutely just a stupid comment.” “You could not identify what it was” in the pocket and the screener “had done everything perfectly,” he will remark. A screener is shown randomly selecting Alhazmi to have his carry-on luggage traced with the explosive detection system. “It was perfect procedure,” Wragg will opine. The fact that the hijacker was chosen for this procedure at random “just shows that we were doing everything we were supposed to,” he will add.
Agents Copy All the Files with Details of the Screeners - The federal agents want details of all the screeners who were working at Dulles Airport this morning and so they go to Argenbright Security’s office at the airport and copy all of the files with information about them. “Anything we had on them was copied, and we copied and copied and copied,” Wragg will recall. He will add that the agents “came back on more than one occasion and asked for the same copies they had already taken earlier.” However, Wragg notices nothing incriminating in the evidence he reviews with the federal agents. He sees no evidence “that any of the hijackers had gone through security at Dulles with any weapon, legal or illegal,” according to investigative journalists Joseph Trento and Susan Trento. (9/11 Commission 8/26/2004, pp. 27; Trento and Trento 2006, pp. 129-130)

The main gate at Bolling Air Force Base.The main gate at Bolling Air Force Base. [Source: US Air Force]A temporary Air Force Operations Center is established at Bolling Air Force Base in Washington, DC, after the original Operations Center at the Pentagon had to be evacuated due to smoke from the burning building coming in. (CNN 10/10/2001; Goldberg et al. 2007, pp. 136; Hebert 9/2011 pdf file) Air Force personnel had been responding to the terrorist attacks in the Operations Center in the basement of the Pentagon. The Air Force’s Crisis Action Team (CAT) was activated in response to the attacks in New York and carried out its activities there (see (9:00 a.m.) September 11, 2001). (Brown 9/19/2001; Yackel 12/2001) Senior officials, including General John Jumper, the Air Force chief of staff, and James Roche, the secretary of the Air Force, arrived at the Operations Center after the Pentagon was hit and assisted the Air Force’s response to the attacks (see After 9:37 a.m. September 11, 2001). (CNN 10/10/2001; Scully 9/11/2003; Goldberg et al. 2007, pp. 136) But as the morning went on, thick smoke from the burning building started coming into the Operations Center and became a major problem. Air Force officials therefore decided to set up a temporary Operations Center at Bolling Air Force Base, just across the Potomac River from the Pentagon. At 12:20 p.m., Air Force leaders and assistants left the Operations Center at the Pentagon, and were flown by helicopter to the replacement facility. Member of the CAT also relocated to the new facility, which is functioning by 1:00 p.m. At the new Operations Center, Air Force Surgeon General Paul Carlton Jr. briefs Roche and Jumper on what medical assistance the Air Force might provide to help the emergency response efforts in New York and the Washington area. The two men approve his plan to send medical personnel and equipment to McGuire Air Force Base in New Jersey, to support the emergency response efforts in New York as required. By 3:00 a.m. on September 12, conditions at the Pentagon will have improved sufficiently for operational command to be moved back to the Air Force’s original Operations Center, and that center will be fully operational again at 5:30 a.m. (Prospectus 9/2006, pp. 3-6 pdf file; Goldberg et al. 2007, pp. 117, 136; Hebert 9/2011 pdf file)

Deena Burnett, whose husband Tom Burnett was on Flight 93, is told by United Airlines it isn’t aware this plane has crashed. Deena had earlier on learned of an aircraft crashing in Pennsylvania, and a police officer with her informed her that this was her husband’s flight. Yet in her own book, published in 2006, Deena Burnett will describe that she now calls “United Airlines and asked about Flight 93. ‘Were there any survivors?’” She will recall: “They said they didn’t know the plane had even crashed. They suggested I call back or they would contact me when they knew something.” According to her own description, Deena appears to make this call shortly before 11:00 a.m. Pacific Time, meaning close to 2:00 p.m. Eastern Time. (Burnett and Giombetti 2006, pp. 71-72 and 79) Yet by 10:15 a.m. ET, United Airlines’ headquarters had confirmed that an aircraft had crashed in Pennsylvania, and believed this was Flight 93 (see (10:07 a.m.-10:15 a.m.) September 11, 2001). (9/11 Commission 8/26/2004, pp. 47) And at 11:17 a.m. ET, the airline had issued a press release confirming the crash of Flight 93 (see 11:17 a.m. September 11, 2001). (United Airlines 9/11/2001) At what time Deena Burnett hears back from United Airlines after making this call is unstated.

The New York City Police Academy.The New York City Police Academy. [Source: Heather Holland / DNAinfo]New York City’s Office of Emergency Management (OEM) establishes an alternate Emergency Operations Center (EOC) at the New York City Police Academy. The OEM’s original EOC, on the 23rd floor of World Trade Center Building 7, was evacuated at around 9:30 a.m. due to a report that more commercial planes were unaccounted for (see (9:30 a.m.) September 11, 2001). (Rashbaum 9/17/2001; 9/11 Commission 5/18/2004 pdf file; 9/11 Commission 7/24/2004, pp. 305, 311) Since then, the OEM command bus has served as the office’s command post (see (Shortly After 9:30 a.m.) September 11, 2001). (9/11 Commission 4/7/2004)
Police Commissioner Recommended Going to the Police Academy - Following the collapse of the North Tower of the WTC, at 10:28 a.m. (see 10:28 a.m. September 11, 2001), Mayor Rudolph Giuliani and the officials with him considered where to set up their operations. After they spent some time at a firehouse (see (After 10:28 a.m.-12:00 pm.) September 11, 2001), Police Commissioner Bernard Kerik recommended they use the Police Academy as their command center since, he will later recall, it is “a centrally located building of modest height and design, and an unlikely target if the terrorists should strike again.” Additionally, it has “phones and meeting rooms, and could be secured easily.” Consequently, the academy, on East 20th Street, was selected as the new location for the EOC. (Kerik 2001, pp. 340-342; 9/11 Commission 4/6/2004; 9/11 Commission 5/19/2004) Giuliani and his entourage arrived there at around midday and were soon at work, planning the city’s response to the terrorist attacks. (Giuliani 2002, pp. 19)
New Operations Center Is Activated Early in the Afternoon - Meanwhile, the New York Police Department and the OEM set up the new EOC in the library at the academy. In the space of around two and a half hours, the facility is fully operational, with phone lines and computers available, and spaces for at least 30 agencies. (9/11 Commission 5/18/2004 pdf file) It is activated at around 2:00 p.m., according to a report by Tricia Wachtendorf of the Disaster Research Center at the University of Delaware. (Wachtendorf 2004, pp. 76)
Phones and Computers Keep Going Down - OEM personnel promptly get to work, in collaboration with other agencies, on the logistics of the rescue operation. Among other things, they set about ordering supplies and equipment for the rescue effort, determining where and how they can move in trucks and heavy machinery, and developing plans for how to move and where to locate the steel and debris from the WTC site. (9/11 Commission 5/18/2004 pdf file) However, they experience problems as they try to carry out their operations. “The phones kept going down, the little computer network we jerry-rigged kept going down, so everything had to be done with pen and paper,” Henry Jackson, deputy director for administration at the OEM who is responsible for setting up the temporary facility, will complain. The EOC will be located at the Police Academy until September 14, when it will move to a larger space at Pier 92 on the Hudson River. (Griscom 10/15/2001; ArcNews 12/2001; 9/11 Commission 5/19/2004)

No relatives of the Flight 93 passengers are waiting at San Francisco International Airport at the time when the plane is scheduled to have arrived there. A counseling center has been set up at the airport for any relatives that might show up, and dozens of clergy members gave gathered at United Airlines’ VIP lounge to await the families. San Francisco Mayor Willie Brown has arranged to come and meet them. But at 11:15 a.m. Pacific Time (2:15 p.m. Eastern Time), when Flight 93 was scheduled to arrive, no family members have shown up, nor have any arrived by midday (3:00 p.m. ET). Willie Brown cancels his trip to meet the families when it appears none will show up. Knight Ridder will suggest the reason no relatives have come is that United Airlines employees contacted many of them before they left home. (Wong 9/12/2001; Rogers and Fernandez 9/12/2001) Also, United Airlines publicly confirmed that Flight 93 had crashed several hours earlier (see 11:17 a.m. September 11, 2001), so passengers’ relatives may have realized for themselves what has happened by now. (United Airlines 9/11/2001) Another possible factor could be that many of the passengers—at least 16 out of a mere 33—were not originally scheduled to be on Flight 93, and only arranged to be on it at the last minute or switched from another flight (see Shortly Before September 11, 2001-Early Morning September 11, 2001), so their relatives may not initially realize they had been on the plane. (Longman 9/11/2002) In contrast, some relatives of passengers on the other three hijacked planes have gone to Los Angeles International Airport, the destination of those planes: The New York Times will describe “a few grieving relatives” there, and the Associated Press describes, “In Los Angeles, several dozen relatives met grief counselors at an airport hotel.” (Associated Press 9/11/2001; Glaberson 9/12/2001)

James L. Jones.James L. Jones. [Source: US Marine Corps]The Navy establishes a new command center at the Navy Annex in Arlington, Virginia, after its original command center was destroyed in the attack on the Pentagon. The original Navy Command Center, located on the first floor of the Pentagon, provided Navy leaders with timely information and intelligence about operations around the world. But it was destroyed, and many of its personnel died, when the Pentagon was hit (see 9:37 a.m. September 11, 2001 and 9:37 a.m. September 11, 2001). (Leiby 1/20/2002; Goldberg et al. 2007, pp. 133) Reportedly, 70 percent of the Navy’s spaces in the Pentagon were damaged or destroyed in the Pentagon attack. (Brown 10/1/2001)
Navy Invited to Join Marines at Navy Annex - General James Jones, the commandant of the Marine Corps, therefore invited several of his Navy counterparts and their staffs to co-locate with the Marine Corps at the Navy Annex. (Brill 1/2002) The Navy Annex is a huge building located a few hundred yards uphill from the Pentagon. It has enough room for 6,000 employees. Currently, about 100 Navy personnel work in it, and most of the space is used by the Marine Corps. (Garamone 9/24/2001; Goldberg et al. 2007, pp. 14; GlobalSecurity (.org) 5/7/2011) It is the location of the Marine Corps Command Center. (Brill 1/2002) Admiral William Fallon, the vice chief of naval operations, has consequently made arrangements for the Navy’s leadership and support personnel to move to the Navy Annex. (Goldberg et al. 2007, pp. 133)
Building Manager Unhappy about Moving People to Navy Annex - At around 3:00 p.m., Coneleous Alexander, a building manager at the Navy Annex, learns from one of the Marine Corps administrative managers of the plan to relocate the Navy Command Center to his building. The new command center will be set up in an area on the fourth floor that, Alexander will later say, “had been demolished for use by the build out for ballistic missiles.” (Alexander 12/21/2001) It is unclear from Alexander’s account whether he means that missiles are being stored at the Navy Annex, or is referring to the Ballistic Missile Defense Organization, which has been housed at the Navy Annex since February this year. (US Department of Defense 11/30/2001; Kadish 5/2/2002) Alexander is unsure whether it is a good idea to move personnel to the Navy Annex. One reason for his uncertainty, he will say, is “the ballistic missiles” being there. He thinks a better choice would be to move people to Henderson Hall, the Marine Corps headquarters, which is located next to the Navy Annex.
Only Mission-Essential Personnel Allowed into Building - All the same, Marines start moving equipment into the Navy Annex, and maintenance crews set up portable air conditioners and exhaust fans for the Navy’s new command center there. It is decided that, due to the fear of another attack, only mission-essential personnel may enter the building. (Alexander 12/21/2001; Goldberg et al. 2007, pp. 133) While some Navy staffs will be able to promptly return to their spaces at the Pentagon, others have to temporarily move to offices at locations that, as well as the Navy Annex, include the Washington Navy Yard and Northern Virginia’s Crystal City office complex.

Gallatin Field Airport in Bozeman, Montana.Gallatin Field Airport in Bozeman, Montana. [Source: Gallatin Field Airport]Several dozen emergency management officials and federal staff from Eastern US states, including Virginia and Washington, DC, are flown back to their home states from Montana. They are among hundreds of emergency management personnel who have been attending the annual conference of the National Emergency Management Association (NEMA) in Big Sky, Montana, which began on September 8 (see September 8-11, 2001). (Natural Hazards Observer 3/2001; DeMers 10/2001 pdf file) The emergency managers learned of the attacks in New York while waiting to participate in a series of conference sessions on domestic preparedness (see After 8:46 a.m. September 11, 2001). (DeMers 10/2001 pdf file; Nagy 9/10/2002) The conference’s organizers then began arranging for military aircraft to fly state emergency management leaders back to their capitals. (Janofsky 9/12/2001)
Seven Hours before Plane Cleared to Fly Managers Home - An Air Force C-17 cargo plane now flies more than 40 emergency managers and federal staff from the airport in Bozeman, Montana, back to their home states. They have had to wait at the airport for more than seven hours while others at the conference site arranged clearance from the FAA for the aircraft to take them home. (DeMers 10/2001 pdf file) Military aircraft reportedly fly about 23 emergency management directors back to their home states on this day. (Murphy 10/11/2001) Ed Jacoby, the director of the New York State Emergency Management Office, was flown back to New York State earlier on (see (After 11:00 a.m.) September 11, 2001). (Borgstrom 10/25/2001; Nagy 9/10/2002) Many of those attending the NEMA conference who are unable to get on emergency military flights to take them home have to instead drive hundreds, or in some cases thousands, of miles to get back to their states. (DeMers 10/2001 pdf file)

An internal FAA memorandum is written, which mentions that Daniel Lewin, a passenger on Flight 11, was shot dead by hijacker Satam Al Suqami, but various agencies and investigations will later determine that the alleged shooting never happened. (Eggen 3/2/2002; General Accounting Office 8/30/2002; 9/11 Commission 2003; 9/11 Commission 8/26/2004, pp. 16-17) The memo, titled “Executive Summary,” is prepared by civil aviation security personnel officials in the aviation command center at FAA headquarters in Washington, DC, and intended for distribution to the office of FAA Administrator Jane Garvey. It is based on information received in the command center from numerous sources throughout the day that was recorded in an official log. (Morrison 2/27/2002; 9/11 Commission 2003; 9/11 Commission 9/11/2003 pdf file) The details of the alleged shooting on Flight 11 come from information entered into the log based on notes made by Janet Riffe, the FAA’s principal security inspector for American Airlines, in which she described a phone conversation she had this morning with Suzanne Clark, a manager of corporate security at American Airlines (see 9:20 a.m. September 11, 2001). (General Accounting Office 8/30/2002; 9/11 Commission 9/11/2003 pdf file)
Memo States that a Flight Attendant Reported a Shooting - The memo states that it is “a summary of the events which have occurred” today and includes brief descriptions of the four hijackings that took place this morning. In its description of the hijacking of Flight 11, it states that at 9:20 a.m., Riffe “was notified by Suzanne Clark of American Airlines corporate headquarters that an onboard flight attendant contacted American Airlines operations center and informed that a passenger located in seat 10B shot and killed a passenger in seat 9B.” The memo names Lewin as the passenger who was killed and Al Suqami as the passenger who shot him. Just one bullet was reported to have been fired, it states. It also states incorrectly that Flight 11 crashed into one of the towers at the World Trade Center at 9:25 a.m. (Federal Aviation Administration 9/11/2001) (Flight 11 actually crashed into the North Tower of the WTC at 8:46 a.m. (see 8:46 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 7) )
Agencies Will Dismiss the Allegation of a Shooting - Various agencies and investigations will determine that the reported shooting on Flight 11 never occurred. After the memo is leaked to the press in 2002, FAA and FBI officials will say the report of a gun on the plane was a mistake. The FAA will say the memo is just a “first draft” and the final draft omits any claim of a gun being fired. FAA spokeswoman Laura Brown will say the mistaken information was due to “a miscommunication” and add that the memo “was corrected that very evening.” (Morrison 2/27/2002; Eggen 3/2/2002; United Press International 3/6/2002)
GAO Will Find No Corroboration for the Allegation - The General Accounting Office (GAO) will conduct a comprehensive investigation of the alleged shooting in which it interviews FAA personnel and senior managers, and American Airlines personnel. Based on these interviews, it will subsequently state, “American Airlines personnel deny ever reporting a shooting on any of the hijacked flights on September 11, 2001.” The GAO will conclude that “there is no information to corroborate a shooting on American Airlines Flight 11.” (General Accounting Office 8/30/2002)
Accounts of Calls from Flight 11 Will Not Support the Allegation - The 9/11 Commission will subsequently also investigate whether there was a shooting on Flight 11 and determine, “The evidence derived from eyewitness accounts of the events that unfolded on [Flight 11] does not support a conclusion that a shooting on the flight is likely to have occurred.” (9/11 Commission 2003) In explaining how it reached its conclusion, the Commission will point out that “authoritative information about whether a shooting occurred on Flight 11 could have come only from individuals on the aircraft who were reporting events to contacts on the ground.” It will note that two flight attendants on Flight 11—Betty Ong and Amy Sweeney—“placed calls to ground contacts to report what was happening on the aircraft.” But, it will state, in none of the tape recordings of these calls and accounts of witnesses to them “is the presence of a gun or the occurrence of a shooting reported.” In contrast, witnesses to the calls stated that the two flight attendants were “quite specific about the presence of knives, and the stabbing or slashing of two crew members and a passenger.” Furthermore, the victim of the alleged shooting is said in the memo to have been in seat 9B, which was the same seat that “according to several of the witness accounts from the aircraft, was assigned to the passenger who was stabbed.” (9/11 Commission 8/26/2004, pp. 16-17) (9B was Lewin’s seat. (Leibovitz 9/11/2013) )
FAA and the FBI Will Find No Evidence of a Gun on Flight 11 - Additionally, the Commission will state that the “FAA has no information which confirms the presence of a gun on… Flight 11” and the FBI has similarly advised that it has “no evidence of a gun being used onboard the aircraft.” (9/11 Commission 2003) The Commission will point out that “while investigators have uncovered evidence of numerous knife purchases by the 19 hijackers leading up to September 11, 2001, there was no evidence that they purchased or possessed firearms.” Furthermore, while the four hijacking teams generally used similar tactics, “No evidence has been uncovered to suggest that the hijackers on any of the other flights [besides Flight 11] used firearms.” The Commission will comment that it “seems unlikely that one of the teams would depart from the tactical discipline of the plotters’ mutual strategy.” (9/11 Commission 8/26/2004, pp. 17)
American Airlines Manager Will Deny that a Shooting Occurred - The Commission will state that in interviews it conducted, while Riffe said the information in the memo was accurate, Clark denied having reported a shooting. The Commission will also mention that around the time the memo was written, someone in the aviation command center contacted American Airlines to verify the account of a shooting and was informed that it was incorrect. American Airlines “reported that it had no information about anyone being shot,” the Commission will state. (9/11 Commission 2003; 9/11 Commission 9/11/2003 pdf file; 9/11 Commission 11/18/2003 pdf file) Most evidence will indicate that, rather than being shot, Lewin had his throat slashed by Al Suqami (see (8:14 a.m.) September 11, 2001). (9/11 Commission 8/26/2004, pp. 16-17; Raskin 2013, pp. 218) However, one other incident supports the allegation in the memo of a shooting on Flight 11. At 8:44 a.m., the operations center at FAA headquarters was told that a passenger on the plane had been shot over a conference call with the FAA’s New England Regional Operations Center (see 8:44 a.m. September 11, 2001). (Federal Aviation Administration 9/2001; General Accounting Office 8/30/2002)
