About 100 members of the 174th Fighter Wing, part of the New York Air National Guard, are deployed to Sultan Air Base, Saudi Arabia, to patrol the no-fly zone over southern Iraq, as part of the ongoing Operation Southern Watch. This is the unit’s second deployment there, its first having been in March 2001. [Post-Standard (Syracuse), 9/11/2001; Post-Standard (Syracuse), 9/12/2001; US Congress, 3/1/2005; 174th Fighter Wing, 12/9/2005] The 174th FW is located at Hancock Field Air National Guard Base, five miles north of Syracuse, in Central New York State. It is currently equipped with 17 F-16 fighters. These are kept in a six-bay shelter where they are, reportedly, “ready to fly in any weather, at a moment’s notice.” [Airman, 1/2001; Post-Standard (Syracuse), 9/25/2001; GlobalSecurity (.org), 4/26/2005] However, Hancock Field is not one of NORAD’s two “alert” sites in the northeast US. [9/11 Commission, 6/17/2004] The unit has 350 full-time staff and 650 part-timers, who work one weekend each month plus two full weeks a year. [Post-Standard (Syracuse), 9/25/2001; Post-Standard (Syracuse), 10/24/2001] The 100 members of the unit who go to Saudi Arabia are due to arrive back at Hancock Field at around 3 p.m. on 9/11, but as a consequence of the day’s events are diverted to Canada. [Post-Standard (Syracuse), 9/14/2001] They will eventually arrive back at the base on September 14. [Post-Standard (Syracuse), 9/15/2001] In the months after 9/11, 174th FW fighters are involved in flying combat air patrols over New York City.

Jackie Chan.Jackie Chan. [Source: Reuters]A scene for a Hollywood movie about a terrorist plot to blow up the World Trade Center was originally scheduled to be filmed at the top of one of the Twin Towers at this time, but the filming has been canceled because the script for the scene is late to arrive. [ABC News, 9/19/2001; Empire, 9/19/2001; Orlando Sentinel, 9/27/2002] The action-comedy movie, titled Nosebleed, which was written in 1999 (see February 1999-September 11, 2001), is set to feature the well-known martial artist and actor Jackie Chan as a window washer at the WTC who uncovers a terrorist plot to bomb the Twin Towers. [Variety, 2/7/1999; Entertainment Weekly, 9/24/2001]
Actor 'Would Probably Have Died' if Filming Took Place - Chan will later tell the Hong Kong newspaper Oriental Daily News, “Filming was scheduled to have taken place at 7:00 a.m. [on September 11] and… I had to be at the top of one of the towers for one of the scenes.” [ABC News, 9/19/2001; Empire, 9/19/2001] The scene, Chan will say, was going to be filmed at the “Top of the World restaurant.” [Orlando Sentinel, 9/27/2002] Presumably he is referring to Windows on the World, the restaurant at the top of the North Tower. Everyone who is in Windows on the World when Flight 11 hits the North Tower at 8:46 a.m. (see 8:46 a.m. September 11, 2001) will subsequently die. [NPR, 9/11/2003] Chan will comment, “I would probably have died if the shooting had gone ahead as planned.” Today’s filming at the WTC has been canceled, reportedly because the script for the scene that would have been filmed is late. [ABC News, 9/19/2001; Empire, 9/19/2001] “The action was good, but, somehow, the script not ready,” Chan will say.
Actor Is in Canada for Another Film - Instead of doing the scene for Nosebleed, Chan is in Toronto, Canada, where filming began the previous day for another movie he is starring in. That movie, The Tuxedo, is an action-comedy that Steven Spielberg is involved in producing. Chan will say of The Tuxedo, “I only did this movie because Steven Spielberg asked me himself.” [Reuters, 6/17/2001; Canoe, 7/11/2001; Orlando Sentinel, 9/27/2002] He will recall learning of the attacks in New York during filming, saying: “After the first shot, I turned around and everyone was looking at one monitor, and nobody had responded to me. They said, ‘Jackie, a plane crashed into the World Trade Center.’ Then we [saw] the second plane crash. We knew it was a terrorist attack and everyone started crying.” Chan will add, “The whole day I was like a walking dead man.” [Columbia Chronicle, 9/23/2002]
Actor Learned 'Secrets' of the WTC in Preparation for Film - Chan has done a lot of groundwork for Nosebleed. “We had visited the [WTC] before September 11,” he will recall. “The producer. My manager. We had dinner upstairs. We were getting all kinds of information. I was going to play a window washer, so they were telling me things like how many windows the building had.” Chan has therefore learned “the ‘secrets’ of the towers—how air pressure was regulated with doors that might be useful as gags in one of his trademark fights—which sides of the buildings one could work on to avoid the wind,” according to the Orlando Sentinel. [Orlando Sentinel, 9/27/2002; Rocky Mountain News, 9/28/2002] Production of Nosebleed will be canceled as a result of the 9/11 attacks. [PBS, 10/24/2001; Village Voice, 12/4/2001]

American Airlines has problems contacting the FAA’s Command Center in Herndon, Virginia, about the problems with its aircraft, according to four managers working at the airline’s System Operations Control (SOC) center in Fort Worth, Texas, on this day. Craig Marquis, Craig Parfitt, Joe Bertapelle, and Mike Mulcahy will later tell the 9/11 Commission that American Airlines has “a hard time on 9/11 in getting in touch with Herndon.” They will say that “[p]recious minutes were lost in building the communications bridge” between the SOC and the Command Center. The cause of these communication problems is unknown. [9/11 Commission, 11/19/2003 pdf file] The SOC has known that there are problems on Flight 11 since 8:21 a.m., when Marquis received a call from a supervisor at the airline’s Southeastern Reservations Office in North Carolina, alerting him to a call that had been received from one of the plane’s flight attendants about the emergency taking place (see 8:21 a.m. September 11, 2001). Presumably the SOC starts trying to contact the FAA Command Center soon after receiving this call. It is known that the SOC will make contact with the Command Center at 9:16 a.m., if not earlier (see 9:16 a.m.-9:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 9, 15] Bill Halleck, an air traffic control specialist at the SOC, is at least able to reach the FAA’s Boston Center regarding Flight 11 at 8:29 a.m. (see 8:29 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 5, 453] The four American Airlines managers will also tell the 9/11 Commission, “In the event that the [American Airlines] SOC was aware that it was the first to know about an incident [with an aircraft], the protocol would have been for the SOC manager on duty [i.e. Marquis] to have immediately autodialed to the Herndon manager on duty [i.e. Ben Sliney] with the information.” However, the FAA “knew what was going on because of the intercepted communications from the cockpit.” [9/11 Commission, 11/19/2003 pdf file] (FAA air traffic controllers have been aware of problems with Flight 11 since around 8:14 a.m., when they lost communication with the plane (see 8:14 a.m.-8:24 a.m. September 11, 2001), and they subsequently hear communications made by the hijackers on the plane, beginning at 8:24 a.m. (see 8:24 a.m. September 11, 2001).

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.” [Boston Globe, 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.” [New York Times, 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.” [Washington Times, 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. [USA Today, 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).

Boston flight control reportedly “notifies several air traffic control centers that a hijack is taking place.” [Guardian, 10/17/2001] This is immediately after Boston controllers heard a transmission from Flight 11, declaring, “We have some planes” (see 8:24 a.m. September 11, 2001), and would be consistent with a claim later made to the 9/11 Commission by Mike Canavan, the FAA’s associate administrator for civil aviation security. He says, “[M]y experience as soon as you know you had a hijacked aircraft, you notify everyone.… [W]hen you finally find out, yes, we do have a problem, then… the standard notification is it kind of gets broadcast out to all the regions.” [9/11 Commission, 5/23/2003] An early FAA report will say only that Boston controllers begin “inter-facility coordination” with New York air traffic control at this time [Federal Aviation Administration, 9/17/2001 pdf file] , but the New York Times reports that controllers at Washington Center also know “about the hijacking of the first plane to crash, even before it hit the World Trade Center.” [New York Times, 9/13/2001] However, the Indianapolis flight controller monitoring Flight 77 claims to not know about this or Flight 175’s hijacking twenty minutes later at 8:56 a.m. (see 8:56 a.m. September 11, 2001). Additionally, the flight controllers at New York City’s La Guardia airport are never told about the hijacked planes and learn about them from watching the news. [Bergen Record, 1/4/2004] Boston Center also begins notifying the FAA chain of command of the suspected Flight 11 hijacking at this time (see 8:25 a.m. September 11, 2001), but it does not notify NORAD for another 6-15 minutes, depending on the account (see (8:37 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.” [Site Selection, 5/2000; Aviation International News, 8/1/2003] Poughkeepsie is about 70 miles north of New York City. [Pittsburgh Post-Gazette, 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. [New York Times, 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]

On 9/11 it is managed by Ben Sliney (not pictured here).The FAA Command Center, the center of daily management of the US air traffic system. On 9/11 it is managed by Ben Sliney (not pictured here). [Source: CNN]The FAA’s Boston Center calls the FAA Command Center and says it believes Flight 11 has been hijacked and is heading toward the New York Center’s airspace. The Command Center immediately establishes a teleconference between the Boston, New York, and Cleveland air traffic control centers, so Boston can help the other centers understand what is happening, in case Flight 11 should enter their airspace. Minutes later, in line with the standard hijacking protocol, the Command Center will pass on word of the suspected hijacking to the FAA’s Washington headquarters (see 8:32 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 19; 9/11 Commission, 8/26/2004, pp. 11; Spencer, 2008, pp. 21]
National Operations Manager Learns of Hijacking - A supervisor at the Command Center promptly passes on the news of the possible hijacking to Ben Sliney, who is on his first day as the national operations manager there. The supervisor says the plane in question is “American Flight 11—a 767 out of Boston for Los Angeles.” According to author Lynn Spencer, “Sliney flashes back to the routine for dealing with hijackings from the days when they were more common.” The procedure is to “[k]eep other aircraft away from the errant plane. Give the pilots what they need. The plane will land somewhere, passengers will be traded for fuel, and difficult negotiations with authorities will begin. The incident should resolve itself peacefully, although the ones in the Middle East, he recalls, often had a more violent outcome.” Apparently not expecting anything worse to happen, Sliney continues to the conference room for the daily 8:30 staff meeting there (see 8:30 a.m.-8:40 a.m. September 11, 2001).
Command Center a 'Communications Powerhouse' - The FAA Command Center is located in Herndon, Virginia, 25 miles from Washington, DC. According to Spencer, it “is a communications powerhouse, modeled after NASA’s Mission Control. The operations floor is 50 feet wide and 120 feet long, packed with tiered rows of computer stations, and at the front, seven enormous display screens show flight trajectories and weather patterns.” The center has nearly 50 specialists working around the clock, planning and monitoring the flow of air traffic over the United States. These specialists work with airlines and air traffic control facilities to fix congestion problems and deal with weather systems. [Spencer, 2008, pp. 1 and 19-20]

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. [Chicago Tribune, 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]

Flight controllers hear a hijacker on Flight 11 say to the passengers: “Nobody move, please, we are going back to the airport. Don’t try to make any stupid moves.” [New York Times, 10/16/2001; Guardian, 10/17/2001; Boston Globe, 11/23/2001; 9/11 Commission, 6/17/2004] This is the third hijacker transmission from Flight 11 heard by Boston Center. Following the previous two transmissions, controller Pete Zalewski had put the plane’s frequency on speakers so that others at the center could hear (see 8:24 a.m. September 11, 2001). This is therefore the first time some of them hear the hijacker’s voice. One controller says out loud, “That is really scary.” [MSNBC, 9/11/2002]

NORAD fails to notify the National Military Command Center (NMCC) at the Pentagon that aircraft have been hijacked before the NMCC initiates a significant event conference in response to the terrorist attacks. [9/11 Commission, 6/9/2004] NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the first hijacking, of Flight 11, at 8:37 a.m. (see (8:37 a.m.) September 11, 2001) and it is alerted to the second hijacking, of Flight 175, at 9:03 a.m. (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20, 23] And yet, according to an after-action report produced by the NMCC, NORAD does not contact the NMCC to alert it to these incidents before the significant event conference commences, at 9:29 a.m. (see 9:29 a.m.-9:34 a.m. September 11, 2001). [9/11 Commission, 6/9/2004]
NORAD Does Not Provide Information to Deputy Director - Captain Charles Leidig, the acting deputy director for operations in the NMCC, will later say that he “does not remember getting a lot of information from NORAD” before the significant event conference begins. [9/11 Commission, 4/29/2004 pdf file] NMCC personnel apparently learn that an aircraft has been hijacked when an officer in the center calls the FAA at 9:00 a.m. (see 9:00 a.m. September 11, 2001).

NORAD First Mentions a Hijacking at 9:33 a.m. - NORAD will apparently talk to the NMCC about a hijacking for the first time at around 9:33 a.m., when its representative on the significant event conference states that they “concur that [a] hijacked aircraft is still airborne [and] heading towards Washington, DC.” [US Department of Defense, 9/11/2001; US Department of Defense, 9/11/2001 pdf file] (They will presumably be referring to the incorrect information that Flight 11 is still in the air after it has crashed into the World Trade Center (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26] )
NORAD Does Not Request a Conference - Additionally, according to the NMCC’s after-action report, NORAD “does not request any conference at [National Command Authority] level” prior to the commencement of the significant event conference. [9/11 Commission, 6/9/2004] The significant event conference is actually initiated by Leidig. The NMCC has an important role to play in an emergency like the current crisis. Its job under these circumstances “is to gather the relevant parties and establish the chain of command between the National Command Authority—the president and the secretary of defense—and those who need to carry out their orders,” according to the 9/11 Commission Report. [9/11 Commission, 4/29/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 37] It is also “the focal point within [the] Department of Defense for providing assistance” when there is a hijacking in US airspace, according to a recent military instruction (see June 1, 2001).

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.

[Source: Family photo]Just after Flight 175 enters the airspace of the FAA’s New York Center (see 8:40 a.m. September 11, 2001), its pilot reports to the air traffic controller now managing the flight a suspicious transmission he had heard on departing Boston’s Logan Airport. The pilot, Captain Victor Saracini, tells the controller, Dave Bottiglia: “We figured we’d wait to go to your center. Ah, we heard a suspicious transmission on our departure out of Boston, ah, with someone, ah, it sounded like someone keyed the mikes and said, ah, ‘Everyone, ah, stay in your seats.’” [New York Times, 10/16/2001; 9/11 Commission, 7/24/2004, pp. 21; Spencer, 2008, pp. 36] Saracini is presumably referring to one of the three radio transmissions from Flight 11, where the voice of a hijacker could be heard (see 8:24 a.m. September 11, 2001 and (8:34 a.m.) September 11, 2001). However, none of these had included the hijacker telling people to stay in their seats, as Saracini describes, although the second and third transmissions included the hijacker telling the passengers, “Nobody move.” [9/11 Commission, 7/24/2004, pp. 19] Bottiglia responds: “Oh, okay. I’ll pass that along.” Referring to the fact that this was the end of the transmission he heard, Saracini adds, “It cut out,” and then asks Bottiglia, “Did you copy that?” [Gregor, 12/21/2001 pdf file; Spencer, 2008, pp. 36-37] This is the last radio transmission from Flight 175. The 9/11 Commission will conclude that the plane is hijacked within the next four minutes (see (Between 8:42 a.m. and 8:46 a.m.) September 11, 2001). [9/11 Commission, 8/26/2004, pp. 20] According to author Lynn Spencer, since controllers are only given information on a need-to-know basis, Bottiglia was unaware there were problems with Flight 11, which has not yet entered his airspace. He touches his computer screen to connect to the hotline for his sector controller, and then reports: “UAL 175 just came on my frequency and he said he heard a suspicious transmission when they were leaving Boston. ‘Everybody stay in your seats’—that’s what he heard… just to let you know.” [New York Times, 10/16/2001; Spencer, 2008, pp. 36-37]

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).

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; Rutgers Law Review, 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).

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; USA Today, 12/20/2001; Federal Emergency Management Agency, 5/1/2002, pp. 1-10; New York Times, 5/26/2002; USA Today, 8/12/2002; Associated Press, 8/21/2002; Newsday, 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). [New York Times, 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. [USA Today, 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).

John Odermatt.John Odermatt. [Source: Queens Gazette]New York City’s Office of Emergency Management (OEM) activates its Emergency Operations Center (EOC) on the 23rd floor of World Trade Center Building 7. The OEM is responsible for managing the city’s response to major incidents, including terrorist attacks. [9/11 Commission, 7/24/2004, pp. 283-284, 293] Its personnel arrived at WTC 7, where it has offices, early this morning to prepare for Tripod, a major biological terrorism training exercise scheduled for September 12 (see September 12, 2001). [Jenkins and Edwards-Winslow, 9/2003, pp. 15 pdf file]
Staffer Is Told to Open the Operations Center - OEM Commissioner John Odermatt and Richard Bylicki, a police sergeant assigned to the OEM, heard the explosion when Flight 11 crashed into the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). As they look out of the window at the burning North Tower, Odermatt debriefs Bylicki and instructs him to open the EOC for a fully staffed operation. Bylicki therefore sets about activating the operations center. [Bylicki, 6/19/2003]
Staffers Call Agencies and Tell Them to Send Their Representatives - EOC personnel start contacting agencies, including the New York Fire and Police Departments and the Department of Health, and instruct them to send their designated representatives to the center. They also call the State Emergency Management Office (SEMO) and the Federal Emergency Management Agency (FEMA), which they ask to send at least five federal urban search and rescue teams. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 293] Meanwhile, Bylicki helps the OEM’s Watch Command handle an “enormous influx” of phone calls, many of which are from senior city officials. [Bylicki, 6/19/2003]
Activation Proceeds without Any Problems - EOC personnel initially struggle to make sense of what has happened at the Twin Towers. [Wachtendorf, 2004, pp. 77] However, the activation apparently proceeds without any problems. Firefighter Timothy Brown, a supervisor at the OEM, is instructed by Calvin Drayton, a deputy director with the OEM, to go up to the 23rd floor of WTC 7 and make sure that personnel are getting the EOC up and running, and the Watch Command is being properly supervised. He goes up to the 23rd floor and first checks the Watch Command. He sees that its supervisor, Mike Lee, has things under control. Then, in the EOC, he sees Michael Berkowitz, a supervisor with the OEM, powering up all the computers and television screens necessary to handle the emergency, and beginning to notify the dozens of agencies that need to send representatives to the center. Berkowitz tells Brown he has the manpower he needs to get the center up and running. “I was very comfortable that OEM was beginning to do what we do in a major emergency,” Brown will later recall. Activating the EOC is something OEM personnel have “drilled for and drilled for and drilled for… and so we were very good at it,” he will comment. [City of New York, 1/15/2002; Project Rebirth, 6/30/2002 pdf file; Firehouse, 1/31/2003]
Center Is Designed for Managing a Crisis - The EOC, which opened in 1999 (see June 8, 1999), is a state-of-the-art facility designed to operate as a stand-alone center from which the city government can operate during a crisis. [City of New York, 2/18/2001] It is one of the most sophisticated facilities of its type in the world. It includes a communications suite, a conference room, a press briefing room, and a large number of staff offices, and has numerous computer-equipped workstations. [Disasters, 3/2003 pdf file] It has enough seating for 68 agencies to operate during an emergency. [City of New York, 2/18/2001] However, it will be evacuated at 9:30 a.m. due to reports of further unaccounted-for planes, according to the 9/11 Commission Report (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 305] Other accounts will indicate that it may be evacuated at an earlier time, possibly even before the second crash at the WTC occurs (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001).

[Source: Yvonne Vermillion/ MagicGraphix.com]White House officials and reporters who are traveling with President Bush in Florida learn that a plane has crashed into the World Trade Center while they are being driven to the Emma E. Booker Elementary School in Sarasota, but Bush is not notified about the crash at this time. [White House, 8/12/2002; St. Petersburg Times, 7/4/2004; Rochester Review, 9/2004] A number of senior officials who are together in a van learn about the crash as their vehicle is pulling into the school’s driveway. Those in the van include White House press secretary Ari Fleischer; White House communications director Dan Bartlett; Bush’s senior adviser, Karl Rove; Bush’s CIA briefer, Mike Morell; and White House photographer Eric Draper. [White House, 8/12/2002; Fleischer, 2005, pp. 138; Studies in Intelligence, 9/2006 pdf file]
Press Secretary Is Contacted by an Assistant - Fleischer is alerted to the crash by Brian Bravo, an assistant in the White House press office. Bravo learned what happened when he was called by a friend in New York who had seen Flight 11 hitting the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), and then saw the television coverage of the incident. In response, he sent a pager message to Fleischer, simply stating, “A plane has hit the World Trade Center.” [White House, 8/8/2002; Fleischer, 2005, pp. 138; Politico Magazine, 9/9/2016] After seeing the message, Fleischer exclaims: “Oh, my God! I don’t believe it! A plane just hit the World Trade Center.” [Albuquerque Tribune, 9/10/2002; Bamford, 2004, pp. 17] He turns to Morell and asks the CIA officer if he knows anything about the incident. Morell says no and that he will make some calls to try and find out more. He will call the CIA’s operations center to see what people there know (see Shortly Before 9:00 a.m. September 11, 2001). [Studies in Intelligence, 9/2006 pdf file; Morell and Harlow, 2015, pp. 47-48]
Other Officials Receive Calls from the White House - Around the time Fleischer is alerted to the crash, Rove is called from the White House by his assistant, Susan Ralston, who tells him what happened at the WTC (see (8:55 a.m.) September 11, 2001). [New Yorker, 9/25/2001; Filipinas, 2/2004] And Bartlett receives a call from his assistant at the White House, who tells him: “There’s just been an incredible accident or something. A plane has hit the World Trade Center.” [White House, 8/12/2002]
Military Officers Are Called about the Crash - In another vehicle in the motorcade, Navy Captain Deborah Loewer, the director of the White House Situation Room, receives a call from Rob Hargis, the senior duty officer in the Situation Room, alerting her to the crash. [Dayton Daily News, 8/17/2003; McClatchy Newspapers, 8/29/2011; Priess, 2016, pp. 239-240] Meanwhile, as his vehicle is arriving at the school, Lieutenant Colonel Thomas Herman, a senior presidential communications officer assigned to the White House, is contacted by his operations center, and notified that a plane has struck one of the Twin Towers and National Security Adviser Condoleezza Rice wants to talk on the phone with the president. [Marist Magazine, 10/2002]
Members of the Press Are Alerted to the Crash - Members of the press traveling in the motorcade also learn about the crash during the journey to the school. Reporter Richard Keil is told what happened when he talks on the phone with a friend who has seen the coverage of the incident on television. Keil then passes on the news to the other reporters and photographers in the press van. And Kia Baskerville, a CBS News White House producer, receives a call on her cell phone from a producer who tells her about the crash. [CBS News, 8/19/2002; Rochester Review, 9/2004]
President Is Not Told about the Crash - And yet, while these people are alerted to the crash, Bush reportedly is not called about it at this time and he will only be told what has happened after he arrives at the school (see (8:55 a.m.) September 11, 2001 and (Shortly After 8:55 a.m.) September 11, 2001). [St. Petersburg Times, 7/4/2004; Rove, 2010, pp. 249-250; Priess, 2016, pp. 240] This is despite the fact that his limousine is “bristling with communications gear,” according to the Los Angeles Times. [Los Angeles Times, 1/24/2001] “In the presidential limo, the communications system is almost duplicative of the White House,” author Philip Melanson will note. [St. Petersburg Times, 7/4/2004] “Yet despite having a secure STU-III phone next to him… and an entire national security staff at the White House,” author James Bamford will comment, “it appears that the president of the United States knew less than tens of millions of other people in every part of the country who were watching the attack as it unfolded.” [Bamford, 2004, pp. 17] “It mystifies me why they didn’t call the president,” Robert Plunket, a reporter who is waiting for the president at the school, will remark. “He’s totally surrounded by state-of-the-art communications equipment and nobody tells him.” [St. Petersburg Times, 7/4/2004]

Alan DeVona.Alan DeVona. [Source: Atlas Shrugs]An officer with the Port Authority Police Department (PAPD) calls for the evacuation of the upper floors of the North Tower of the World Trade Center over a PAPD radio channel. Transcripts of PAPD radio transmissions will show that at 8:49 a.m., three minutes after Flight 11 crashed into the North Tower (see 8:46 a.m. September 11, 2001), the PAPD officer talks to the PAPD desk, which is in Building 5 of the WTC, just northeast of the North Tower. He says: “Start doing the evac, the upper levels. Have the units put on the Scott air packs.” The officer at the PAPD desk then radios all PAPD units and tells them to “bring Scott air packs [to] One World Trade,” i.e. the North Tower. [Port Authority of New York and New Jersey, 9/11/2001, pp. 2 pdf file; Port Authority of New York and New Jersey, 11/12/2001, pp. 16 pdf file; National Institute of Standards and Technology, 9/2005, pp. 195]
Patrol Sergeant Recalls Requesting Evacuation - It is unclear which PAPD officer requests the evacuation at this time. According to some accounts, Alan DeVona, the PAPD patrol sergeant at the WTC, makes the request. [Port Authority of New York and New Jersey, 11/12/2001, pp. 16 pdf file; Dwyer and Flynn, 2005, pp. 78] DeVona will later recall that he had just walked out from the PAPD desk in WTC 5 when he heard the explosion as Flight 11 hit the North Tower. Along with his colleague, Anthony Basic, he radioed the PAPD desk and reported that the top floors of the North Tower were on fire, due to a “possible aircraft collision.” He headed into the North Tower to coordinate with emergency agencies as they arrived there. DeVona will recall that he then “radios to have all WTC police units get Scott air packs and begin evacuation of [the North Tower].” He will subsequently be “approached by numerous PAPD units as they entered the lobby” of the North Tower, and he “dispatches them through the concourse to evacuate the complex.” [Devona, 3/28/2002, pp. 24 pdf file]
Police Commander Recalls Requesting Evacuation - However, Captain Anthony Whitaker, the PAPD commanding officer at the WTC, will also say that he calls for the evacuation of the WTC around this time. Whitaker was on duty in the shopping mall beneath the Twin Towers when Flight 11 hit the North Tower. [Dwyer and Flynn, 2005, pp. 78] He heard a “strange roar” and saw a “gigantic fireball” coming out of the lobby of the North Tower. He then contacts the PAPD desk in WTC 5. Whitaker will recall, “I had no idea what had just happened, but I knew it was bad.” Therefore, he will say, “I ordered the cop at the desk to begin a full-scale evacuation of the entire complex.” This will mean the evacuation of “both towers and the adjoining buildings.” Whitaker contacts one of his sergeants and then, he will recall, “we started placing Port Authority cops in strategic locations in the shopping mall to direct the evacuation.” Whitaker will say that after 9/11, he is repeatedly asked, “Why did you give that order to evacuate at that particular time?” following the first crash, but before the second plane hit the WTC. His explanation will be: “It just occurred to me that whatever was going on—and I still didn’t know what that was—was beyond my ability as a commanding officer of that facility to do anything about it. So it seemed to me that the only prudent thing to do was start a full-scale evacuation and get everybody out of there.” [Fink and Mathias, 2002, pp. 23-24; Murphy, 2002, pp. 179-181]
Evacuation Orders Cannot Be Heard by Fire Safety Directors - At 9:00 a.m., Whitaker will call for an evacuation of the entire WTC complex (see 8:59 a.m.-9:02 a.m. September 11, 2001). However, both that instruction and the current one are given over PAPD radio channel W, which cannot be heard by the deputy fire safety directors in the Twin Towers, who are able to make announcements to the buildings’ occupants over the public address systems. [WTC News, 8/1995 pdf file; Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; 9/11 Commission, 7/24/2004, pp. 293; National Institute of Standards and Technology, 9/2005, pp. 195, 201] An announcement advising workers to evacuate will only go out over the public address system in the South Tower at 9:02 a.m. (see 9:02 a.m. September 11, 2001). And attempts to order workers to evacuate the North Tower are unsuccessful because that building’s public address system was damaged by the plane crash (see (Between 8:47 a.m. and 8:55 a.m.) September 11, 2001). [New York Times, 5/18/2004]
PAPD Investigates All Reports of Fires at WTC - The WTC is a Port Authority property, which means it is patrolled by the PAPD—the Port Authority’s independent police agency. Members of the PAPD respond to “thefts, injuries, fires, all species of crisis large and small, almost always more quickly than the city emergency responders could get there,” according to New York Times reporters Jim Dwyer and Kevin Flynn. “By plan,” Dwyer and Flynn will write, “the PAPD checked out every report of fire” and “its officers were trained in at least rudimentary firefighting.” [Dwyer and Flynn, 2005, pp. 78]

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. [USA Today, 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.” [PBS, 4/30/2002; Dwyer and Flynn, 2005, pp. 72] The announcement is made two or possibly three times, according to USA Today. [USA Today, 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.” [USA Today, 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.” [USA Today, 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). [ABC News, 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).

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. [Washington Post, 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). [Vanity Fair, 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.” [Vanity Fair, 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.

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).

One of the two fighter pilots who took off in response to the hijacked Flight 11 is told by air traffic control that Flight 11 has crashed into the World Trade Center, and yet both pilots will later claim they are unaware of this crash until after 9:03 a.m., when Flight 175 hits the WTC. [Federal Aviation Administration, 9/11/2001; Cape Cod Times, 8/21/2002; ABC News, 9/11/2002; Filson, 10/2/2002; Filson, 10/22/2002; 9/11 Commission, 2004] Lieutenant Colonel Timothy Duffy and Major Daniel Nash took off in their F-15s from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), but were unaware that at the same time, Flight 11 was crashing into the WTC (see 8:46 a.m. September 11, 2001). [Filson, 2003, pp. 57; 9/11 Commission, 7/24/2004, pp. 20]
Controller Tells Pilot that Flight 11 Crashed into WTC - Duffy has just checked in with the air traffic controller at the FAA’s Boston Center who is working at the Cape Sector radar position, and the controller has given him a new heading to fly toward (see 8:54 a.m.-8:55 a.m. September 11, 2001). The controller now asks Duffy, “I understand you’re going out to look for American 11, is that correct?” Duffy replies, “Affirmative.” The controller then tells Duffy that Flight 11 has crashed. He says, “Okay, I just got information that the aircraft has been, uh, crashed into the World Trade Center, so I’m not quite sure what your intentions are, if you’re still going to head that way or you may want to talk to your operations.” Duffy responds, “Okay, we’re going to go over and talk to Huntress right now.” (“Huntress” is the call sign for NORAD’s Northeast Air Defense Sector, NEADS.) [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 2004] Although Duffy contacts NEADS (see (8:56 a.m.-8:57 a.m.) September 11, 2001), it is unclear whether he talks about the crash, as he indicates he is going to, since, according to the 9/11 Commission Report, “there are no NEADS recordings available of the NEADS senior weapons director and weapons director technician position responsible for controlling the Otis [Air National Guard Base] scramble” (see (8:30 a.m.-3:00 p.m.) September 11, 2001). [9/11 Commission, 1/7/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 459] It is also unclear whether Duffy passes on the information about Flight 11 hitting the WTC to Nash. But in later interviews, both pilots will claim they were unaware of Flight 11 hitting the WTC until they were informed that a second aircraft had hit the WTC, shortly after that second crash occurred (see (9:03 a.m.) September 11, 2001 and 9:06 a.m.-9:07 a.m. September 11, 2001). [9/11 Commission, 2004; Spencer, 2008, pp. 84]
Pilots Deny Learning of First Crash - The Cape Cod Times will report that Nash “doesn’t even recall hearing that the first plane hit.” [Cape Cod Times, 8/21/2002] Nash will tell author Leslie Filson that when he and Duffy are informed of the second plane hitting the WTC, they are “still under [the] impression [that] American 11 was still airborne” and are “shocked, because we didn’t know the first one had even hit.” [Filson, 10/2/2002] And Nash will tell the 9/11 Commission that he “does not remember at which point during the morning of 9/11 he heard of the first crash at the WTC.” He will say he does “remember that the FAA controller he communicated with during flight told him of the second crash,” but add that “this was strange to hear at the time, since he had not been told of the first.” [9/11 Commission, 10/14/2003 pdf file] Duffy will tell ABC News that when he is informed of the second crash, “I thought we were still chasing American 11.” [ABC News, 9/11/2002] He will tell Filson that when he learns of this second crash, “I didn’t know [the] first one hit” the WTC. [Filson, 10/22/2002] And he will tell the 9/11 Commission that when he “received word that a second aircraft had hit the WTC,” he “still thought they were responding to a hijacked American [Airlines] airliner.” [9/11 Commission, 1/7/2004 pdf file]

Lieutenant Colonel Timothy Duffy, one of the two fighter pilots who took off in response to the hijacked Flight 11, contacts NORAD’s Northeast Air Defense Sector (NEADS) to request information on his target, but apparently neither Duffy nor the person he speaks with at NEADS mention that Flight 11 has already hit the World Trade Center during the call, even though both men should already be aware of the crash. [Federal Aviation Administration, 9/11/2001; Filson, 10/22/2002; Filson, 2003, pp. 60; 9/11 Commission, 1/7/2004 pdf file] Duffy and another pilot, Major Daniel Nash, took off from Otis Air National Guard Base at 8:46 a.m. (see 8:46 a.m. September 11, 2001), but they were unaware that at the same time, Flight 11 was crashing into the WTC (see 8:46 a.m. September 11, 2001). [Filson, 2003, pp. 57; 9/11 Commission, 7/24/2004, pp. 20] Duffy has just spoken to an air traffic controller at the FAA’s Boston Center (see 8:54 a.m.-8:55 a.m. September 11, 2001) and ended the call saying he would talk to NEADS “right now.” [Federal Aviation Administration, 9/11/2001] Duffy will later recall that he contacts NEADS at about 8:56 a.m. or 8:57 a.m. [9/11 Commission, 1/7/2004 pdf file]
Duffy Told His Target Is over JFK Airport - Duffy presumably talks with Steve Hedrick at NEADS, since Hedrick is responsible for controlling the two Otis fighters. [9/11 Commission, 10/27/2003 pdf file] As soon as he has checked in with NEADS, Duffy will recall, “I authenticate to make sure I’ve got the right person.” He then asks for “bogey dope,” meaning information on his target—Flight 11—“to try to find out where the contact is.” [Filson, 10/22/2002; Filson, 2003, pp. 60] Duffy is told, incorrectly, that his target is over New York’s JFK International Airport. Duffy replies, “Okay, I know where that is,” and then, he will recall, “we started heading right down to Long Island.” [Aviation Week and Space Technology, 6/3/2002; ABC News, 9/11/2002]
WTC Crash Apparently Not Discussed - However, it appears that neither Duffy nor the person he speaks with at NEADS mention the plane crash at the WTC during their conversation. Duffy will say that when he is subsequently informed that a second plane has hit the WTC (see (9:03 a.m.) September 11, 2001 and 9:06 a.m.-9:07 a.m. September 11, 2001), he is unaware that Flight 11 has already hit the WTC. [ABC News, 9/11/2002; Filson, 10/22/2002; 9/11 Commission, 1/7/2004 pdf file] And yet Duffy and personnel at NEADS have already been informed of that first crash.
Pilot and NEADS Previously Notified of Crash - Duffy has just been told of the crash during his conversation with the Boston Center controller (see 8:55 a.m. September 11, 2001). [Federal Aviation Administration, 9/11/2001] NEADS personnel learned of it at 8:51 a.m. (see 8:51 a.m. September 11, 2001), although there is now some confusion on the NEADS operations floor over whether the plane that crashed was indeed Flight 11 (see 8:55 a.m.-8:57 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 20; Vanity Fair, 8/1/2006] It will later be impossible to ascertain exactly what is said in the current conversation between Duffy and NEADS. Although tape recorders should be recording every radio channel at NEADS, because of a “technical issue,” the positions of Hedrick and his weapons director technician, Bradley Gardner, are supposedly not recorded (see (8:30 a.m.-3:00 p.m.) September 11, 2001). [9/11 Commission, 5/25/2004; 9/11 Commission, 7/24/2004, pp. 459; Vanity Fair, 8/1/2006]
Duffy Searches for Flight 11 on Radar Scope - Duffy will recall that following the call with NEADS, he is looking at his radar scope “to try and find a radar contact over the Kennedy sector with the hijacked aircraft.” Duffy will again contact NEADS to request “bogey dope” a few minutes later, and during that call is informed of the second plane hitting the WTC.

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.” [Popular Mechanics, 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).

Anthony Whitaker.Anthony Whitaker. [Source: ABC News]Sergeant Alan DeVona, an officer with the Port Authority Police Department (PAPD), calls for the evacuation of the Twin Towers over a PAPD radio channel, and his colleague, Captain Anthony Whitaker, then calls for the evacuation of the entire World Trade Center complex, but their orders are apparently not passed on [Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; 9/11 Commission, 5/18/2004 pdf file; Dwyer and Flynn, 2005, pp. 78-79; National Institute of Standards and Technology, 9/2005, pp. 200-202] DeVona, the PAPD patrol sergeant at the WTC, is currently in the lobby of the North Tower, coordinating with emergency agencies as they arrive there. [Devona, 3/28/2002, pp. 24 pdf file] Whitaker, the PAPD commanding officer at the WTC, is outside the Twin Towers, looking up at the burning North Tower. [Fink and Mathias, 2002, pp. 25; Murphy, 2002, pp. 184]
Officers Request Evacuation of the WTC - At 8:59 a.m., DeVona calls for the evacuation of the Twin Towers. “As soon as we’re able,” he says over the PAPD radio channel, “I want to start a building evacuation, Building 1 [i.e. the North Tower] and Building 2 [i.e. the South Tower], till we find out what caused this.” Immediately after DeVona says this, at 9:00 a.m., Whitaker makes a similar request over the same radio channel. “Let’s begin an evacuation of the entire complex,” he says. “All buildings, copy?” [Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; National Institute of Standards and Technology, 9/2005, pp. 200-201] Unlike DeVona, Whitaker is ordering the evacuation of not just the Twin Towers, “but also the five other buildings throughout the 16-acre complex—the mercantile exchange, offices of major investment banking concerns, and government agencies, including the FBI, the Secret Service, and the CIA,” according to New York Times reporters Jim Dwyer and Kevin Flynn. [Dwyer and Flynn, 2005, pp. 79] Whitaker has decided to evacuate the WTC complex “because of the danger posed by highly flammable jet fuel from Flight 11,” which crashed into the North Tower at 8:46 a.m. (see 8:46 a.m. September 11, 2001), and “because of the magnitude of the calamity in the North Tower,” according to the 9/11 Commission. [9/11 Commission, 5/18/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 293]
Request Is the Second Time Evacuation Is Called For - Whitaker will later say that his current request is the “second time” he has called for the evacuation of the WTC complex. He will recall making his previous request—for “a full-scale evacuation of the entire complex”—shortly after Flight 11 crashed. [Fink and Mathias, 2002, pp. 23-25; Murphy, 2002, pp. 180-181, 184-185] Transcripts of PAPD radio transmissions will show that an evacuation was requested at 8:49 a.m., but only for the upper floors of the North Tower (see 8:49 a.m. September 11, 2001). [Port Authority of New York and New Jersey, 9/11/2001 pdf file; National Institute of Standards and Technology, 9/2005, pp. 195] And according to some accounts, that request was made by DeVona, not Whitaker. [Port Authority of New York and New Jersey, 11/12/2001, pp. 16 pdf file; Devona, 3/28/2002, pp. 24 pdf file; Dwyer and Flynn, 2005, pp. 78]
Officer Repeats Order, for the Written Record - At 9:01 a.m., an officer at the PAPD desk in Building 5 of the WTC asks if they should evacuate their building. DeVona instructs the officer to wait, saying, “Stand by on Building 5.” Whitaker then asks the officer at the PAPD desk if they have started a “chrono log” yet. [Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; National Institute of Standards and Technology, 9/2005, pp. 201] A “chrono” is a written record of what the PAPD is doing. [Murphy, 2002, pp. 182] The officer replies, “That’s affirmative.” At 9:02 a.m., Whitaker repeats his previous instruction, apparently to make sure it is officially recorded. He says: “For the chrono, evacuate all buildings in the complex. You copy? All building in the complex.” The officer at the PAPD desk acknowledges the instruction and then radios all PAPD units in the field, and tells them to evacuate “all tenants in the buildings… at the Trade Center.” [Port Authority of New York and New Jersey, 9/11/2001 pdf file; Port Authority of New York and New Jersey, 11/12/2001, pp. 19 pdf file; National Institute of Standards and Technology, 9/2005, pp. 202]
Orders Not Passed on to Other Agencies - It is unclear whether DeVona and Whitaker’s orders to evacuate the WTC are passed on. Their orders are given over PAPD radio channel W, which cannot be heard by the deputy fire safety directors in the Twin Towers, who are able to make announcements over the buildings’ public address systems. [WTC News, 8/1995 pdf file; 9/11 Commission, 7/24/2004, pp. 293; National Institute of Standards and Technology, 9/2005, pp. 200-202] According to the 9/11 Commission, there is “no evidence” that the orders are “communicated to officers in other Port Authority Police commands or to members of other responding agencies.” [9/11 Commission, 5/18/2004 pdf file] Despite this, an announcement is made over the public address system in the South Tower, advising workers to evacuate, at 9:02 a.m. (see 9:02 a.m. September 11, 2001). Attempts to order workers to evacuate the North Tower are unsuccessful because that building’s public address system was damaged by the plane crash (see (Between 8:47 a.m. and 8:55 a.m.) September 11, 2001).

In the NORAD operations center in Cheyenne Mountain, Colorado, workers see the second aircraft crashing into the World Trade Center live on television. [Gazette (Colorado Springs), 10/7/2001] Major General Rick Findley, NORAD’s director of operations, later says that he now realizes “it was not an accident but a coordinated attack.” Then, he recalls, “At about that moment in time, every phone in this cab, and every phone over in the command center, and every phone in all the centers in this building were ringing off the hook.” Master Corporal Daniel Milne, the emergency action controller in the operations center, will similarly recall, “The feeling was total disbelief. Then the phones started ringing like crazy.” [Canadian Broadcasting Corporation, 9/11/2002; Legion Magazine, 11/2004] It is unclear what causes all the phones to simultaneously ring. According to Aviation Week and Space Technology magazine, after the second tower is hit, “Calls from fighter units… started pouring into NORAD and sector operations centers, asking, ‘What can we do to help?’” (see (After 9:03 a.m.) September 11, 2001) [Aviation Week and Space Technology, 6/3/2002] So this could be one factor. Also, a 1996 article in Airman magazine had quoted Stacey Knott, a technician in the NORAD operations center. She’d said, “Things can be pretty quiet in here.” However, “One of the busiest times is during exercises. This room fills up.… The phones are ringing off the hook, and I’ve got phones in each hand.” [Airman, 1/1996] On this morning, those in Cheyenne Mountain are in fact participating in a major exercise called Vigilant Guardian. [Aviation Week and Space Technology, 6/3/2002; CNN, 9/11/2006] This is reportedly only canceled “shortly after” the second attack (see (Shortly After 9:03 a.m.) September 11, 2001) [Airman, 3/2002; Filson, 2003, pp. 59] So it is plausible that this is also a factor in causing all the phones to suddenly ring. A similar thing appears to occur in the National Military Command Center (NMCC) at the Pentagon. According to a news article based on the recollections of two officers who are there, after the second plane hits the WTC, “Phones in the center began ringing off the hook.” [American Forces Press Service, 9/7/2006] Rick Findley later suggests that all the ringing phones are not a hindrance for NORAD, claiming, “The good news is we had lots of people here and we already had an operational architecture. We already had the command and control, the network, the phones, the data links. Everything was already in place that enabled us to react to the situation.” [Canadian Broadcasting Corporation, 9/11/2002]

The 119th is based at Langley Air Force Base, Virgnina.Amraam missiles being loaded onto a 119th Fighter Wing jet at an unknown time on the day of 9/11. The 119th is based at Langley Air Force Base, Virgnina. [Source: William Quinn]Shortly after the second World Trade Center crash, calls from fighter units begin “pouring into NORAD and sector operations centers, asking, ‘What can we do to help?’” From Syracuse, New York, a commander of the 174th Fighter Wing of the New York Air National Guard calls and tells Colonel Robert Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS): “Give me 10 [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 [Amraams].” Marr replies, “I want it all.” [Aviation Week and Space Technology, 6/3/2002; News 10 Now, 9/12/2006] Reportedly, Marr says: “Get to the phones. Call every Air National Guard unit in the land. Prepare to put jets in the air. The nation is under attack.” [Newhouse News Service, 1/25/2002] Canadian Major General Rick Findley, based in Colorado and in charge of NORAD on this day, reportedly has his staff immediately order as many fighters in the air as possible. [Ottawa Citizen, 9/11/2002] However, according to another account, NEADS does not accept the offers until about an hour later. The Toledo Blade will report, “By 10:01 a.m., the command center began calling several bases across the country for help.” [Toledo Blade, 12/9/2001] The 9/11 Commission will conclude that an order for other bases to prepare fighters to scramble is not given until 9:49 a.m. In fact, it appears the first fighters from other bases to take off are those from Syracuse at 10:42 a.m. (see 10:42 a.m. September 11, 2001). This is over an hour and a half after Syracuse’s initial offer to help, and not long after a general ban on all flights, including military ones, is lifted at 10:31 a.m. (see 10:31 a.m. September 11, 2001). These are apparently the fourth set of fighters scrambled from the ground. Previously, three fighters from Langley Air Force Base, two from Otis Air National Guard Base, and two from Toledo, Ohio, were scrambled at 10:01 a.m. (see 10:01 a.m. September 11, 2001), but did not launch until 15 minutes later.

[Aviation Week and Space Technology, 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.” [Newhouse News Service, 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. [Politico Magazine, 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 FAA Command Center in Herndon, Virginia.The FAA Command Center in Herndon, Virginia. [Source: Federal Aviation Administration]Ben Sliney, the national operations manager at the FAA’s Herndon Command Center, puts the word out that he wants all air traffic control facilities around the US to inform him of anything unusual that occurs with the flights they are handling. In response, news of suspicious activity quickly starts coming in to the Command Center. [Spencer, 2008, pp. 125-126]
Command Center Calls Field Facilities - Sliney wants air traffic control facilities to notify him of anything out of the ordinary, such as a radar target disappearing from the radar scope, loss of communication with an aircraft, or an aircraft making an unauthorized change of course. He also wants to know immediately of any glitches that occur, even if these are common, everyday problems, such as a flight deviating from its course, missing a frequency change, overlooking a radio call, or getting a transponder code wrong. The center’s controllers at each regional desk therefore start calling their field facilities, and ask them to report any unusual occurrences. [9/11 Commission, 7/22/2003 pdf file; Spencer, 2008, pp. 125] The Command Center has telecommunications lines to all the major air traffic control facilities in the US, which enables it to reach out to those facilities and establish the big picture about aircraft activity. [Freni, 2003, pp. 64]
'More and More' Responses Received - Following the call for information, numerous reports of suspicious activity are received from the air traffic control facilities. [Spencer, 2008, pp. 125-126] Linda Schuessler, the deputy director of system operations at the Command Center, will later recall, “[W]e started getting more and more calls about bomb threats, about aircraft that we had lost communication or radar identification with.” [Aviation Week and Space Technology, 12/17/2001]
Center Lists Suspect Aircraft - Sliney wants a list compiled of the reportedly suspicious aircraft. A dry-erase board is set up in the middle of the room. On it a manager keeps track of the reports that are coming in, writing down where each suspect aircraft was last seen, who was working it, where the flight originated, and where it is going. Another person contacts the field facilities to follow up on the reports. [9/11 Commission, 7/22/2003 pdf file; Spencer, 2008, pp. 126]
Two Dozen Suspicious Flights - Author Pamela Freni will later describe, “[F]or the next several hours the call signs and status” of every suspicious aircraft will be recorded. Command Center personnel call “airline operations centers, trying to determine any crises on each flight. Only when each plane landed or was found safe did its identification information disappear from the board. Upward to two dozen were listed at one time, but ultimately the number was whittled to 11 highly suspicious cases” (see (9:09 a.m. and After) September 11, 2001). “Nine of those airplanes would land safely. Two of them—AA 77 and UA 93—would not.” [Freni, 2003, pp. 64-65]

After being given a phone number she needs to call for more information, the woman at NEADS replies: “[D]o me a favor and have them call us? We cannot call out for some reason.” [North American Aerospace Defense Command, 9/11/2001]
bullet At around 10:31 a.m., someone from the 1st Fighter Wing, which is the host unit at Langley Air Force Base in Virginia, calls NEADS.

Daniel Bueno.Daniel Bueno. [Source: Discovery Channel]At “approximately 9:15 a.m.,” according to the 9/11 Commission, Daniel Bueno, a supervisor at the FAA’s Boston Center, asks the FAA’s Herndon Command Center to contact all the FAA centers nationwide and instruct them to issue an alert, informing all airborne aircraft of the events unfolding in New York and advising them to heighten their cockpit security. Boston Center air traffic controllers have recently issued a similar alert to all aircraft in their airspace (see 9:09 a.m.-9:10 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 25-26] However, the 9/11 Commission will conclude, “We have found no evidence to suggest that the Command Center acted on this request or issued any type of cockpit security alert.” [9/11 Commission, 7/24/2004, pp. 23] According to author Lynn Spencer, “The request never makes it to Ben Sliney,” the national operations manager at the Command Center. “Tragically, it is lost in the confusion and never gets past the staff person monitoring Sliney’s desk as events rapidly spiral out of control.” [Spencer, 2008, pp. 99] But Ellen King, a Command Center manager, offers a different explanation. She will tell the 9/11 Commission that the FAA culture and mindset on 9/11 are such that the FAA “would never have relayed this message directly to all pilots.… [T]he FAA would pass situational awareness to the airline company representatives who, in turn, would determine if such action was necessary.” [9/11 Commission, 8/26/2004, pp. 26 and 92]

The FAA’s New England regional office calls the FAA’s Herndon Command Center, and asks it to tell Cleveland Center to contact Delta Air Lines Flight 1989 and advise it to use extra cockpit security. The reason the New England regional office makes this request is unclear. [9/11 Commission, 7/24/2004, pp. 10] As the 9/11 Commission will describe, apparently in response to the request, “[A]t 9:19 the FAA… Command Center in Herndon ordered controllers to send a cockpit warning to Delta 1989 because, like American 11 and United 175, it was a transcontinental flight departing Boston’s Logan Airport.” [9/11 Commission, 7/24/2004, pp. 455] Minutes earlier, the FAA’s Boston Center asked the Command Center to contact the nation’s FAA centers and instruct them to tell all airborne aircraft to increase their cockpit security (see (9:15 a.m.) September 11, 2001). The Command Center’s instruction to air traffic controllers about Delta 1989 is apparently an exception, as the 9/11 Commission will say it found “no evidence to suggest that the Command Center acted on this request.” [9/11 Commission, 7/24/2004, pp. 23; 9/11 Commission, 8/26/2004, pp. 25-26] Delta 1989 will subsequently be 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).

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; Vanity Fair, 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.” [Associated Press, 9/11/2001]

Having just received an incorrect report that Flight 11—which has already hit the World Trade Center—is still airborne and heading toward Washington (see 9:21 a.m. September 11, 2001), technicians at NORAD’s Northeast Air Defense Sector (NEADS) try, unsuccessfully, to locate the aircraft on their radar screens. [Spencer, 2008, pp. 137-139] At NEADS, Major James Anderson says the hijackers are “probably not squawking anything anyway,” meaning their plane’s transponder is not broadcasting a signal. He adds, “I mean, obviously these guys are in the cockpit.” Major Kevin Nasypany, the mission crew commander, replies, “These guys are smart.” Another member of staff adds, “Yeah, they knew exactly what they wanted to do.” [Vanity Fair, 8/1/2006] After giving the order to launch the F-16s kept on alert at Langley Air Force Base (see 9:23 a.m. September 11, 2001), Nasypany calls out, “I need more trackers!” He needs his technicians to locate the hijacked plane on radar so that his weapons team can pass on its coordinates to the Langley fighters. But the trackers are unable to find the transponder code for Flight 11 on their radar screens. They begin calling up, one at a time, the tracks on their screens that are in the airspace between New York and Washington, and attach a tag to each after it has been identified. One technician draws a line on a map between New York and Washington, showing the area across which Flight 11 would be traveling. It includes Philadelphia, Atlantic City, and Baltimore. He looks at his radar screen and sees there are hundreds of tracks in that area. [Spencer, 2008, pp. 138-139] Colin Scoggins, the military liaison at the FAA’s Boston Center, who gave NEADS the incorrect report about Flight 11, will later say he’d only heard the plane was still airborne and heading for Washington on a conference call between FAA centers. According to Vanity Fair, air traffic controllers “were never tracking an actual plane on the radar after losing American 11 near Manhattan, but if it had been flying low enough, the plane could have gone undetected.” [Vanity Fair, 8/1/2006]

[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; Christian Science Monitor, 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. [Vanity Fair, 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.

FAA Administrator Jane Garvey. [Source: FAA]Time magazine later reports that Jane Garvey, head of the FAA, “almost certainly after getting an okay from the White House, initiate[s] a national ground stop, which forbids takeoffs and requires planes in the air to get down as soon as is reasonable. The order, which has never been implemented since flying was invented in 1903, applie[s] to virtually every single kind of machine that can takeoff—civilian, military, or law enforcement.” Military and law enforcement flights are allowed to resume at 10:31 a.m. (see 10:31 a.m. September 11, 2001) A limited number of military flights—the FAA will not reveal details—are allowed to fly during this ban. [Time, 9/14/2001] Garvey later calls it “a national ground stop… that prevented any aircraft from taking off.” [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001] Transportation Secretary Norman Mineta later says he was the one to give the order: “As soon as I was aware of the nature and scale of the attack, I called from the White House to order the air traffic system to land all aircraft, immediately and without exception.” [US Congress. Senate. Committee on Commerce, Science and Transportation, 9/20/2001] According to Mineta, “At approximately 9:45… I gave the FAA the final order for all civil aircraft to land at the nearest airport as soon as possible.” [9/11 Commission, 5/23/2003] At the time, 4,452 planes are flying in the continental US. A later account states that Ben Sliney, the FAA’s National Operations Manager, makes the decision without consulting his superiors, like Jane Garvey, first. It would be remarkable if Sliney was the one to make the decision, because 9/11 is Sliney’s first day on the job as National Operations Manager, “the chess master of the air traffic system.” [USA Today, 8/12/2002] When he accepted the job a couple of months earlier, he had asked, “What is the limit of my authority?” The man who had promoted him replied, “Unlimited.” [USA Today, 8/13/2002] Yet another account, by Linda Schuessler, manager of tactical operations at the FAA Command Center where Sliney was located, says, “… it was done collaboratively… All these decisions were corporate decisions. It wasn’t one person who said, ‘Yes, this has got to get done.’” [Aviation Week and Space Technology, 12/17/2001] About 500 planes land in the next 20 minutes, and then much more urgent orders to land are issued at 9:45 a.m. (see (9:45 a.m.) September 11, 2001).

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. [USA Today, 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).

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. [USA Today, 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; USA Today, 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). [USA Today, 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; USA Today, 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.” [USA Today, 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). [USA Today, 8/13/2002; 9/11 Commission, 10/2/2003 pdf file; Spencer, 2008, pp. 168; USA Today, 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).

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; American Forces Press Service, 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).

According to the 9/11 Commission, by 9:30 a.m. American Airlines confirms that Flight 11 crashed into the World Trade Center. This is almost 45 minutes after the attack occurred. Earlier, at around 9:16, an American air traffic control specialist had only told the FAA that the airline “thought” the first plane to hit the WTC had been Flight 11 (see 9:16 a.m.-9:18 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 15-16] However, Colin Scoggins, a civilian manager at the FAA’s Boston Center, will later claim that American Airlines refused to confirm that its plane had hit the WTC for several hours afterwards. He will claim this lack of confirmation was a factor in his mistakenly reporting that Flight 11 was still airborne at 9:21 (see 9:21 a.m. September 11, 2001). He says, “When we phoned United [after the second tower was hit], they confirmed that United 175 was down, and I think they confirmed that within two or three minutes. With American Airlines, we could never confirm if it was down or not, so that left doubt in our minds.” [Vanity Fair, 8/1/2006] Yet American Airlines had the advantage over United that two of its flight attendants on Flight 11 had been in extensive contact by phone, up until a couple of minutes before their plane crashed. Amy Sweeney had been talking to Michael Woodward, a manager at the American Airlines flight services office at Boston’s Logan Airport (see 8:22 a.m.-8:24 a.m. September 11, 2001). And Betty Ong had been in contact with the airline’s Southeastern Reservations Office in North Carolina, with details of this call being continuously relayed to its System Operations Control (SOC) in Fort Worth, Texas (see 8:21 a.m. September 11, 2001).

At the FAA’s Cleveland Center, an air traffic controller hears a transmission, presumably made by Flight 93 hijacker-pilot Ziad Jarrah, stating: “Ladies and gentlemen: Here the captain, please sit down, keep remaining sitting. We have a bomb on board. So, sit.” [9/11 Commission, 7/24/2004, pp. 12; 9/11 Commission, 8/26/2004, pp. 39] As the 9/11 Commission later notes, “Like [Mohamed] Atta on Flight 11, Jarrah apparently did not know how to operate the communication radios; thus his attempts to communicate with the passengers were broadcast on the [air traffic control] channel.” [9/11 Commission, 8/26/2004, pp. 98] While this communication is assumed to have come from Flight 93, an early FAA report states that it came “from an unknown origin.” [Federal Aviation Administration, 9/17/2001 pdf file] According to Newsweek, just prior to the communication, Cleveland Center controllers heard the sound of screaming from the flight. [Newsweek, 9/22/2001] The 9/11 Commission states that, around the time of the transmission, the plane’s cockpit voice recording indicates “that a woman, most likely a flight attendant, was being held captive in the cockpit. She struggled with one of the hijackers who killed or otherwise silenced her.” [9/11 Commission, 7/24/2004, pp. 12; 9/11 Commission, 8/26/2004, pp. 39] Though the Cleveland air traffic controller understands the hijacker’s communication, he responds to it: “Calling Cleveland Center, you’re unreadable. Say again, slowly.” He also notifies his supervisor who passes the information up the chain of command, and the FAA’s Command Center is subsequently informed, “United 93 may have a bomb on board.” At 9:34 the Command Center will relay this information to FAA headquarters (see 9:34 a.m. September 11, 2001).

According to the 9/11 Commission, word of Flight 93’s hijacking reaches FAA headquarters. By this time, headquarters has established an open line of communication with the FAA Command Center at Herndon, Virginia. It had instructed the center to poll all flight control centers about suspect aircraft. So, at this time, the Command Center passes on Cleveland’s message: “United 93 may have a bomb on board.” The FAA headquarters apparently does not forward this information to the military, despite having the responsibility for doing so. Ben Sliney, the FAA’s national operations manager at its Herndon Command Center, will later recount, “I do know that all the information was being relayed to headquarters and, at least as far as we were concerned, it should have been. We thought it had been given to the military at each juncture.” The Command Center continually updates FAA headquarters on Flight 93 until it crashes. [9/11 Commission, 6/17/2004; CBC, 9/12/2006]

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]

Government buildings in Washington, DC, are not evacuated prior to the attack on the Pentagon at 9:37 a.m. As CNN will later describe, even after the attacks on the World Trade Center and the FAA’s warning to the military of a hijacked aircraft apparently heading toward Washington (see 9:21 a.m. September 11, 2001 and (9:24 a.m.) September 11, 2001), “the federal government failed to make any move to evacuate the White House, Capitol, State Department, or the Pentagon.” [CNN, 9/16/2001] Although a slow evacuation of the White House begins at around 9:20 a.m. (see (9:20 a.m.) September 11, 2001), it is not until 9:45 a.m. that the Secret Service orders people to run from there (see (9:45 a.m.) September 11, 2001). [CNN, 9/11/2001; CNN, 9/12/2001; ABC News, 9/11/2002] Other government buildings, including the Capitol (see 9:48 a.m. September 11, 2001), the Justice Department, the State Department, and the Supreme Court, will not be evacuated until between 9:45 a.m. and 10:45 a.m. [US News and World Report, 9/14/2001; US Department of State, 8/15/2002] Robert Bonner, who was recently nominated as Commissioner of Customs, will estimate that he was evacuated from the Treasury Department at “about 9:35 a.m.” [9/11 Commission, 1/26/2004; US Department of Homeland Security, 9/20/2004] But other accounts will say the Treasury Department was not evacuated until after the Pentagon attack. [Associated Press, 9/11/2001; Reuters, 9/11/2001; US Department of State, 9/11/2002] Furthermore, journalist and author Robert Draper will describe, even after the State and Treasury Departments have been evacuated, “no agents thought to take charge of the Commerce Department, which housed 5,000 employees.” [Draper, 2007, pp. 143] According to CNN, prior to the Pentagon attack: “[N]either the FAA, NORAD, nor any other federal government organ made any effort to evacuate the buildings in Washington. Officials at the Pentagon said that no mechanism existed within the US government to notify various departments and agencies under such circumstances [as occur today].” [CNN, 9/16/2001]

From the White House Situation Room, counterterrorism “tsar” Richard Clarke gives the instruction for fighter jets to establish patrols over all major US cities. Clarke has been talking with the FAA over the White House video conference, and his deputy, Roger Cressey, has just announced that a plane hit the Pentagon. According to his own recollection, Clarke responds: “I can still see [Defense Secretary Donald] Rumsfeld on the screen [for the Pentagon], so the whole building didn’t get hit. No emotion in here. We are going to stay focused.” He orders Cressey: “Find out where the fighter planes are. I want combat air patrol over every major city in this country. Now.” [Clarke, 2004, pp. 7-8; Australian, 3/27/2004] A combat air patrol (CAP) is an aircraft patrol over a particular area, with the purpose of intercepting and destroying any hostile aircraft before they reach their targets. [US Department of Defense, 4/12/2001] It is unclear how long it takes for CAPs to be formed over all major cities, as Clarke requests. At 9:49, NORAD Commander Ralph Eberhart will direct all the US’s air sovereignty aircraft to battle stations (see 9:49 a.m. September 11, 2001), but bases have reportedly been calling into NORAD and asking for permission to send up fighters since after the second WTC crash (see (After 9:03 a.m.) September 11, 2001). [Aviation Week and Space Technology, 6/3/2002; 9/11 Commission, 6/17/2004] At around 11:00 a.m. Eberhart will implement a plan called SCATANA, which clears the skies and gives the military control over US airspace (see (11:00 a.m.) September 11, 2001).

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. [Vanity Fair, 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. [USA Today, 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. [USA Today, 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. [New York Times, 10/18/2001; 9/11 Commission, 7/24/2004, pp. 32] Like those two aircraft, it is a Boeing 767. [USA Today, 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; Vanity Fair, 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. [Associated Press, 9/11/2001; New York Times, 10/18/2001; USA Today, 8/13/2002; Arizona Daily Star, 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; Vanity Fair, 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]

The transponder signal from Flight 93 ceases. [CNN, 9/17/2001; MSNBC, 9/3/2002; MSNBC, 9/11/2002; 9/11 Commission, 6/17/2004] However, the plane can be—and is—tracked using primary radar by Cleveland flight controllers and at United headquarters. Altitude can no longer be determined, except by visual sightings from other aircraft. The plane’s speed begins to vary wildly, fluctuating between 600 and 400 mph before eventually settling around 400 mph. [Longman, 2002, pp. 77, 214; 9/11 Commission, 6/17/2004]

After learning that Delta flight 1989 may have been hijacked from Boston flight control (see 9:39 a.m. September 11, 2001), NEADS calls Cleveland flight control, which is handling the flight, to discuss this. [9/11 Commission, 7/24/2004, pp. 14] Although Cleveland flight control has been aware that United 93 has been hijacked since before 9:30, it apparently fails to mention this to NEADS. According to the 9/11 Commission, the NMCC is not notified of United 93’s hijacking until 10:03 (see 10:03 a.m. September 11, 2001).

[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; Vanity Fair, 8/1/2006]

[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.” [Airman, 12/1999; US Air Force, 2004; 9/11 Commission, 7/24/2004, pp. 17]

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).

The FAA’s Cleveland Center receives a call from NORAD’s Northeast Air Defense Sector (NEADS), incorrectly notifying it that Delta Air Lines Flight 1989 is a confirmed hijacking. A supervisor then rushes around the center, informing all the controllers and managers of this. [9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 2004]
Cleveland Realized Delta 1989 Not Hijacked - At around 9:30 a.m., Cleveland Center air traffic controllers heard the sounds from Flight 93 as it was being hijacked, but initially thought these came from Delta 1989 (see (9:28 a.m.-9:33 a.m.) September 11, 2001). [USA Today, 8/13/2002] Due to the Delta pilots’ normal responses to subsequent radio transmissions, John Werth—the controller monitoring both flights—concluded that the hijacked aircraft was in fact Flight 93. [9/11 Commission, 10/1/2003 pdf file; USA Today, 9/11/2008] However, at around 9:39, the FAA’s Boston Center guessed that Delta 1989 might be hijacked and called NEADS to report the plane as a possible hijacking (see 9:39 a.m. September 11, 2001). [9/11 Commission, 2004; 9/11 Commission, 7/24/2004, pp. 28] NEADS then begins alerting FAA centers of this. [Vanity Fair, 8/1/2006]
NEADS Calls Cleveland Center - Greg Dukeman, the military operations specialist in the traffic management unit at Cleveland Center, receives a call from a female member of staff at NEADS, one of its ID technicians. He passes the call on to supervisor Kim Wernica. The caller says Delta 1989 is “a confirmed hijack.” Wernica then goes “running back and forth” around the center, informing controllers and managers of what she has been told. [North American Aerospace Defense Command, 9/11/2001; 9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 10/2/2003 pdf file; 9/11 Commission, 2004]
Controller Disputes NEADS's Information - Wernica rushes up to John Werth and tells him, “It’s the Delta, it’s the Delta!” She says a military liaison on the phone has confirmed that the Delta jet has been hijacked. Werth responds that he is pretty sure that Flight 93, not Delta 1989, has been hijacked. When Wernica returns a few moments later, Werth tells her that Delta 1989 is “fine—at least for now.” Wernica consults again on the phone and then comes back, saying, “They said it’s a confirmed hijack and a bomb threat.” Werth thinks to himself that the bomb threats had come from Flight 93 (see (9:32 a.m.) September 11, 2001 and (9:39 a.m.) September 11, 2001), and is therefore convinced the caller must be confusing the two flights. He tells Wernica, “Tell them they’re full of it!” [9/11 Commission, 10/1/2003 pdf file; USA Today, 9/11/2008]

Defense Secretary Donald Rumsfeld’s office, and acting Joint Chiefs of Staff Chairman Richard Myers’ office, report to the NMCC teleconference that they are still trying to track down Rumsfeld and Myers, respectively, and bring them into the conference.

Myers’ whereabouts in the period after the Pentagon crash have not been fully explained (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001).

General Ralph Eberhart.General Ralph Eberhart. [Source: NORAD]As the 9/11 Commission will later describe, the commander of NORAD, General Ralph Eberhart, now directs “all air sovereignty aircraft to battle stations, fully armed.” [9/11 Commission, 7/24/2004, pp. 38] Being at “battle stations” means the pilots have to suit up into their flight gear and get into their planes, ready to start the engines and taxi out if a scramble order follows. [Spencer, 2008, pp. 27] Senior NORAD officials will subsequently give the order to launch available fighter jets across the nation (see (Between 9:50 a.m. and 10:00 a.m.) September 11, 2001). [Spencer, 2008, pp. 178, 180]
Clarke Requested Combat Air Patrols - A few minutes earlier, according to his own account, counterterrorism “tsar” Richard Clarke, who is in the White House Situation Room, learned of an aircraft hitting the Pentagon and instructed his deputy: “Find out where the fighter planes are. I want combat air patrol over every major city in this country” (see (Between 9:38 a.m. and 9:45 a.m.) September 11, 2001). Whether Clarke’s actions influenced Eberhart to issue his order is unknown. [Clarke, 2004, pp. 7-8]
Fighter Units Possibly Offered Help Much Earlier - The Toledo Blade will state that NORAD’s Northeast Air Defense Sector (NEADS) only begins calling bases across the US to request help “[b]y 10:01 a.m.” [Toledo Blade, 12/9/2001] But an article in Aviation Week and Space Technology magazine will indicate that NORAD and NEADS began receiving calls from various fighter units, asking, “What can we do to help?” right after the second World Trade Center tower was hit at 9:03, when it had become obvious the US was under attack (see (After 9:03 a.m.) September 11, 2001). [Aviation Week and Space Technology, 6/3/2002] It is therefore unclear why the instruction to put available fighters on battle stations—or to scramble them—was not issued significantly earlier.

In the battle cab at NORAD’s Northeast Air Defense Sector (NEADS), Colonel Robert Marr instructs his troops to contact every Air National Guard unit in the Northeast US and tell them to get their fighter jets airborne. [Spencer, 2008, pp. 180] NEADS has already launched the four fighters in the Northeast US that are kept on alert, ready to take off at a moment’s notice: Two F-15s were scrambled from Otis Air National Guard Base at 8:46 (see 8:46 a.m. September 11, 2001) and two F-16s were scrambled from Langley Air Force Base at 9:24 (see 9:24 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 17, 20, 27]
NEADS Calls Air National Guard Units - Marr now realizes these four jets are not enough, and tells his troops: “The nation is under attack. Get ‘em in the air!” Officers in the NEADS battle cab and on its operations floor begin calling Air National Guard units, one after another. The NEADS officers are surprised to find that wing commanders have been anticipating their call for help, and have already started arming fighter jets. According to author Lynn Spencer: “Although wing commanders do not necessarily have the authority to arm their planes with live missiles, nor Marr the authority to call them into action, these are not ordinary times. Marr can’t help but think that the incredible response is due to the fact that the Guard units are Title 32, or state-owned. They report to the governors of their respective states, and the wing commanders have every confidence that their governors will support them.” [9/11 Commission, 10/30/2003 pdf file; Spencer, 2008, pp. 180]
Time of Order Unclear - Exactly when Marr instructs his officers to contact the Air National Guard units is unclear. It appears to be at around 9:50 a.m., or some time shortly after. At the Continental US NORAD Region (CONR) headquarters in Florida, CONR commander Major General Larry Arnold began contacting all three CONR sectors (which includes NEADS) at around 9:45 a.m., after learning the Pentagon had been hit and realizing the attacks were no longer isolated to New York. His instruction to the sectors was, “Generate, generate, generate!” meaning, “Get as many fighters as you can into the sky now!” [Spencer, 2008, pp. 177-178] General Ralph Eberhart, the commander of NORAD, directed “all air sovereignty aircraft to battle stations, fully armed,” at 9:49 a.m. (see 9:49 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 38] But “battle stations” means only that pilots get into their aircraft with the engines turned off, so they are ready to launch if a scramble order follows. [Filson, 2003, pp. 55; Spencer, 2008, pp. 27] The Toledo Blade will report, “By 10:01 a.m., [NEADS] began calling several bases across the country for help.” [Toledo Blade, 12/9/2001] According to the Newhouse News Service, though, Marr apparently gave his order significantly earlier. It will report that, when the South Tower was hit at 9:03, NEADS personnel “looked to Col. Robert Marr, who rallied the operation: Get to the phones. Call every Air National Guard unit in the land. Prepare to put jets in the air. The nation is under attack” (see (After 9:03 a.m.) September 11, 2001). [Newhouse News Service, 1/25/2002] Air National Guard jets will reportedly take off from Toledo Express Airport in Ohio at 10:17 a.m., in response to NEADS’s call for help, and, according to Spencer, NEADS instructs Otis Air Base to launch all its available aircraft at around 10:20 a.m. (see (10:20 a.m.) September 11, 2001).

Swanson / US Air Force]NORAD’s Northeast Air Defense Sector (NEADS) contacts Selfridge Air National Guard Base in Michigan to arrange for two of its F-16 fighter jets that are out on a training mission to intercept a suspicious aircraft. 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; Vanity Fair, 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). [USA Today, 8/13/2002; USA Today, 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.” [Vanity Fair, 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.” [ABC News, 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; Wolverine Guard, 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; Vanity Fair, 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 [USA Today, 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.” [Mount Clemens-Clinton-Harrison Journal, 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).

Douglas Champagne.Douglas Champagne. [Source: David Kujawa / US Air Force]Although NORAD’s Northeast Air Defense Sector (NEADS) has contacted Selfridge Air National Guard Base in Michigan, reportedly to arrange that two of its F-16s be diverted from a training mission to intercept either Flight 93 or Delta Air Lines Flight 1989 (accounts conflict over which aircraft is concerned), the pilots of those jets apparently never receive an order to intercept a plane, and so return directly to their base. [Filson, 2003, pp. 68, 71; Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006; Spencer, 2008, pp. 178] However, some accounts will claim the pilots are indeed ordered to intercept the suspect aircraft. [ABC News, 8/30/2002; Associated Press, 8/30/2002; Post-Standard (Syracuse), 3/27/2005; Spencer, 2008, pp. 188]
Jets Returning from Training Mission - The F-16s, piloted by Lieutenant Colonel Tom Froling and Major Douglas Champagne of the 127th Wing, had taken off from Selfridge Air National Guard Base at around 8:50 a.m. for a routine training mission at Grayling Range in central northern Michigan. The two pilots were oblivious to the attacks taking place in New York and Washington. [Filson, 2003, pp. 68; GlobalSecurity (.org), 4/26/2005; Wolverine Guard, 9/2006 pdf file] When they started heading back to Selfridge after completing their training mission, they began hearing “unusual radio traffic” as air traffic controllers began diverting flights from their original destinations. [Mount Clemens-Clinton-Harrison Journal, 9/6/2006]
Pilots Learn of Plane Hitting Pentagon - Froling will later recall: “Something strange was occurring and I couldn’t put my finger on what was happening. I could hear [the FAA’s] Cleveland Center talking to the airlines and I started putting things together and knew something was up.” [Filson, 2003, pp. 68-70] Champagne hears an air traffic controller stating that a plane has crashed at the Pentagon. He then hears the Cleveland Center announcing a “demon watch,” which means pilots have to contact their operations center for more information.
Commander Asks if Pilots Have Used up Their Ammunition - When Champagne calls the Selfridge base, his operations group commander, General Michael Peplinski, wants to know if he and Froling have used up their ammunition during the training mission. Champagne will recall: “[Peplinski] asked if we had expended all our munitions and specifically asked if we had strafed. We replied that all ordnance was gone. I assumed we had strafed without clearance and had injured someone down range. We had no idea what was happening on the Eastern seaboard.” [Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006]
Pilots Directed to Return to Base - According to author Lynn Spencer, because a commander with the 127th Wing agreed to turn the two F-16s over to NEADS (see (9:55 a.m.) September 11, 2001), Champagne and Froling are instructed to call NEADS. When they do so, they are ordered to intercept Delta 1989. [Spencer, 2008, pp. 178, 180, 188] But according to other accounts, they are “ordered south in case United Airlines 93 was targeting Chicago.” [ABC News, 9/11/2002; Post-Standard (Syracuse), 3/27/2005] However, according to two reports based on interviews with Champagne, Peplinski only instructs the two pilots to return to their base and land on its auxiliary runway.
Pilots Apparently Not Ordered to Intercept Aircraft - Accounts based on interviews with the pilots will make no mention of the jets being directed to intercept Delta 1989 or Flight 93. According to Champagne, the air traffic controller’s announcement that an aircraft hit the Pentagon “was the only indication we received that other aircraft and buildings were involved.” Champagne will say that “he and his colleague never received orders to intercept [Flight 93] in any way.” The two pilots “had no ammunition… and only an hour’s worth of fuel remaining. And as they approached Selfridge amid the puzzling radio transmissions, they still were oblivious to what was transpiring.” [Filson, 2003, pp. 68-70; Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006]
Jets Land at Base - The two F-16s land back at Selfridge Air National Guard Base at 10:29 a.m. [9/11 Commission, 10/27/2003 pdf file] As Champagne pulls in his aircraft, his friend Captain Sean Campbell approaches and mouths the words to him: “It’s bad. It’s really, really bad.” [Wolverine Guard, 9/2006 pdf file; Mount Clemens-Clinton-Harrison Journal, 9/6/2006]

According to the 9/11 Commission: “An Air Force lieutenant colonel working in the White House Military Office [joins] the [NMCC’s air threat] conference and state[s] that he had just talked to Deputy National Security Adviser Stephen Hadley. The White House request[s]: (1) the implementation of Continuity of Government measures, (2) fighter escorts for Air Force One, and (3) the establishment of a fighter combat air patrol over Washington, DC.” [9/11 Commission, 6/17/2004] Counterterrorism “tsar” Richard Clarke gave the order to implement the Continuity of Government plan a few minutes earlier, from inside the White House Situation Room (see (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). Before that, he had requested a fighter escort for Air Force One (see (Between 9:30 a.m. and 9:37 a.m.) September 11, 2001) and combat air patrols over all major US cities (not just Washington), according to his own recollection (see (Between 9:38 a.m. and 9:45 a.m.) September 11, 2001).

NORAD’s Northeast Air Defense Sector (NEADS) receives a call from a NORAD unit in Canada, reporting another suspected hijacked aircraft that is heading south from Canada, across the border toward Washington, DC. [Vanity Fair, 8/1/2006]
Aircraft Reported on Chat System - A member of staff at NEADS relays to their colleagues that the aircraft is from an “unknown departure airport, heading towards Washington,” but they do not “know any codes or anything” else about it. [North American Aerospace Defense Command, 9/11/2001] Another member of staff at NEADS calls the Canadian unit for more information. A Lance Corporal Nicholson there says only that he has seen “something on the chat” about a “possible” aircraft. [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] (Nicholson is presumably referring to NORAD’s computer chat system. [Spencer, 2008, pp. 139] )
Fighter Unit Contacted - According to author Lynn Spencer, NEADS battle commander Colonel Robert Marr contacts a military unit in Syracuse, New York, to get fighter jets sent after the suspicious flight. [Spencer, 2008, pp. 223] However, the first jets to launch from Syracuse will not take off until 10:42 a.m. (see 10:42 a.m. September 11, 2001). [Post-Standard (Syracuse), 9/12/2001]
Report Is a False Alarm - The suspected hijacking is soon revealed to be a false alarm. Nicholson will call from Canada and tell NEADS: “Be advised… that our [intelligence team] is not assessing that there is an actual aircraft problem. It’s just that there could be problems from our area.… There’s no actual aircraft that we suspect as being a danger.” He will add that his intelligence people “haven’t got any particular aircraft in mind.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
Numerous Erroneous Reports - This is one of the numerous mistaken reports of hijackings received during the course of the morning (see (9:09 a.m. and After) September 11, 2001). According to Vanity Fair: “In the barrage of information and misinformation, it becomes increasingly difficult for the controllers [at NEADS] to keep count of how many suspected hijackings are pending. So far, it is known that three have hit buildings, but given the uncertainty about the fates of American 11 and American 77—no one knows yet that this is the plane that hit the Pentagon—the sense at NEADS is that there are possibly three hijacked jets still out there, and who knows how many more yet to be reported.” At the time NEADS is informed of the suspicious aircraft coming in from Canada, “no one on the military side is aware that United 93 has been hijacked.” [Vanity Fair, 8/1/2006]

NORAD’s Northeast Air Defense Sector (NEADS) contacts an Air National Guard unit in Toledo, Ohio, and requests that it launch two fighter jets in response to the attacks. [WTOL, 9/11/2006; Lynn Spencer, 2008; Spencer, 2008, pp. 178]
First Time that Unit Has Answered a NORAD Request - The 180th Fighter Wing of the Ohio Air National Guard is based at Toledo Express Airport. It has 20 F-16 fighter jets and about three dozen pilots. [Toledo Blade, 12/9/2001] Its “primary mission” is “to provide combat ready F-16C and support units capable of deploying worldwide in minimum response time.” [180th Fighter Wing, 9/19/2001; GlobalSecurity (.org.), 10/21/2001] The unit is not one of NORAD’s seven alert facilities around the US, and this is believed to be the first time it has ever answered a request for help from NORAD. [Airman, 12/1999; Toledo Blade, 12/9/2001]
Call due to Concern over Delta 1989 - According to author Lynn Spencer, a weapons technician at NEADS makes the call to the 180th FW due to concerns about Delta Air Lines Flight 1989, which is incorrectly thought to have been hijacked (see 9:39 a.m. September 11, 2001). [Spencer, 2008, pp. 177-178] NEADS has already contacted units in Minnesota and Michigan about this aircraft (see (Shortly After 9:41 a.m.) September 11, 2001 and (9:55 a.m.) September 11, 2001). [9/11 Commission, 1/23/2004 pdf file; Vanity Fair, 8/1/2006] The weapons technician calls the Toledo unit after Master Sergeant Joe McCain gives an update across the NEADS operations floor: “Delta [19]89! Hard right turn!” According to Spencer, the weapons technician knows the 180th FW is much better positioned than the Selfridge unit’s fighters are to reach Delta 1989. [Spencer, 2008, pp. 178]
NORAD Commander Gives Different Explanation - But according to Larry Arnold, the commander of the Continental United States NORAD Region, the weapons technician’s call might also be in response to concerns over Flight 93. Arnold will say that NEADS calls the 180th FW “because we thought [Flight] 93 or Delta Flight 1989 might be headed toward Chicago.” [Filson, 2003, pp. 71] Two Toledo pilots who initially answer the call from NEADS appear to believe the call is a joke, but their wing commander then picks up the line and responds appropriately (see 10:01 a.m. September 11, 2001). [Spencer, 2008, pp. 178-179]
Unit Prepared for Crisis Like This - Although it is not one of NORAD’s alert facilities, Lt. Col. Gary Chudzinski, a former commander of the 180th FW, will later comment that the Toledo unit has always been aware that it could be alerted to crises such as the current one, “but you just don’t expect it.” According to General Paul Sullivan, who heads all Ohio Air National Guard units, the 180th FW’s pilots practice “air interception,” but a typical mission focuses on either a plane ferrying drugs or enemy fighters approaching America’s coasts. [Airman, 12/1999; Toledo Blade, 12/9/2001] Two 180th FW jets will take off from the Toledo unit at 10:17 a.m. (see 10:17 a.m. September 11, 2001). [Toledo Blade, 12/9/2001; WTOL, 9/11/2006]

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; Daily Telegraph, 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.

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; Vanity Fair, 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.” [Vanity Fair, 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]

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.” [Aviation Week and Space Technology, 6/3/2002; News 10 Now, 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).

Mission Unclear - It is unclear what role the two jets play in defending the nation. Toledo Air National Guard officials will later refuse to talk about this morning’s events, even in the general terms permitted by the military. [Toledo Blade, 12/9/2001] According to Spencer, NEADS wanted the 180th FW jets to respond to Delta Air Lines Flight 1989, which is incorrectly thought to have been hijacked and will land in Cleveland at around 10:18 (see (10:18 a.m.) September 11, 2001). The 9/11 Commission will similarly say the Toledo jets are ordered to intercept Delta 1989. [Federal Aviation Administration, 9/16/2001; 9/11 Commission, 7/24/2004, pp. 27-28; Spencer, 2008, pp. 177-178] But Larry Arnold, the commander of the Continental United States NORAD Region, will say the 180th FW was contacted “because we thought [Flight] 93 or Delta Flight 1989 might be headed toward Chicago.” [Filson, 2003, pp. 71] NEADS battle commander Colonel Robert Marr will say the two F-16s “never had a track close enough that they were directed to engage. [But] if a valid direction had come from the appropriate level to engage a target, or shoot down a target at some time, they could have done that.”
Response Is 'Very Quick' - Marr will describe the 180th FW’s response to NEADS’s request for assistance as “very, very, very quick.” [Toledo Blade, 12/9/2001] However, the fourth hijacked aircraft, Flight 93, has already crashed by the time the two jets take off (see (10:06 a.m.) September 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; USA Today, 8/13/2002; 9/11 Commission, 7/24/2004, pp. 27-28; WKYC, 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; USA Today, 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). [WKYC, 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; USA Today, 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. [Associated Press, 9/11/2001; Associated Press, 9/11/2001; Federal Aviation Administration, 9/17/2001 pdf file]

Jon Treacy.Jon Treacy. [Source: US Air Force]Otis Air National Guard Base in Cape Cod, Massachusetts, receives the order from NORAD’s Northeast Air Defense Sector (NEADS) to launch all its available fighter jets.
Commander Briefs Pilots - A number of Otis pilots that were recalled from a training mission about an hour earlier (see (9:25 a.m.-9:45 a.m.) September 11, 2001) and other pilots that have recently come to the base from their homes are gathered in front of the operations desk. Squadron commander Lieutenant Colonel Jon Treacy tells them: “This is what we know. This is clearly a national emergency. Two aircraft have been hijacked and flown into the World Trade Center. The Pentagon has been attacked. We need to get all our jets ready to go because we’re not sure where this is heading. We have information that there are more coming.” He instructs the pilots: “You must be prepared to meet any surprise.… You may be taking out an airliner. You must engage. You cannot fail. Our nation is relying on us.” He gives them their assignments, saying whether they are required to fly now or whether they will be needed later on, to take over when other pilots have landed.
Launch Order Received - Just after Treacy finishes giving his briefing, someone comes into the room yelling out that NEADS has called the base with important orders. The person says, “We have to get everything we have airborne now!” [Spencer, 2008, pp. 244-245] NEADS started contacting Air National Guard bases around the Northeast US by about 10:00 a.m., with the instruction to get their fighters airborne (see (Between 9:50 a.m. and 10:00 a.m.) September 11, 2001). [Toledo Blade, 12/9/2001; Spencer, 2008, pp. 180]
Pilots Head Out, but Most Jets Not Yet Armed - Treacy yells at his men, “Go, go, go!” and then the pilots run out to their aircraft. But, according to author Lynn Spencer, since the time the group of pilots returned from their training mission, “there has not been time to do much more than fuel their jets.” Most of the base’s fighters “are still unarmed. Despite the furious pace of the weapons handlers, only a handful of jets have been uploaded with some armament.” The first two F-15s that take off from Otis Air Base in response to the NEADS order will both be unarmed (see (10:30 a.m.) September 11, 2001). [Spencer, 2008, pp. 245-246] Another two F-15s will take off shortly after them with their guns loaded, but one of them will have only one missile loaded instead of two (see (Shortly After 10:30 a.m.) September 11, 2001). [Cape Cod Times, 9/11/2006; Richard, 2010, pp. 15-16, 18] Two F-15s that are kept on alert at Otis Air Base took off at 8:46 a.m. in response to the hijacking of Flight 11 (see 8:46 a.m. September 11, 2001).

Brigadier General David Wherley, the commander of the District of Columbia Air National Guard (DCANG) at Andrews Air Force Base, near Washington, wants his fighter jets to intercept a suspicious aircraft coming down the Potomac River toward the capital, which is apparently thought to be Flight 93, although that plane has already crashed (see (10:06 a.m.) September 11, 2001). [Washington Post, 4/8/2002; Filson, 2003, pp. 79-81; 9/11 Commission, 8/28/2003]
Numerous Suspicious Aircraft - According to the Washington Post, the DCANG has learned there are “about a half-dozen suspicious aircraft in the air across the country, among them hijacked United Airlines Flight 93, on a path toward Washington.” Wherley will add: “Nobody knew it had crashed. We just knew there was an airplane out there that could be coming to Washington. We knew the threat was real.”
Fighters Launched due to False Report - The first three DCANG fighters to take off in response to the attacks are ordered to go after this alleged inbound aircraft. [Washington Post, 4/8/2002] Lieutenant Colonel Phil Thompson, the chief of safety for the DC Air National Guard, will later recall: “We had something coming down the Potomac at low altitude. Brigadier General Wherley is standing here, and we’ve got the tower with the Secret Service agent, and they want us to launch anything we’ve got. And the general said, ‘Do it.’” [Filson, 2003, pp. 81] DCANG pilot Billy Hutchison, who takes off at 10:38 a.m. (see (10:38 a.m.) September 11, 2001), will describe, “There was an aircraft coming down the Potomac that they needed me in the air for” that had to “be prevented from reaching the DC area.” He is told this aircraft is “coming from Pennsylvania.” [9/11 Commission, 2/27/2004] And pilot Marc Sasseville, who, along with Heather Penney Garcia, takes off at 10:42 a.m. (see 10:42 a.m. September 11, 2001), later says: “We all realized we were looking for an airliner—a big airplane. That was Flight 93; the track looked like it was headed toward DC at that time.” [Aviation Week and Space Technology, 9/9/2002; Vogel, 2007, pp. 446]
Incorrect Report Comes from Secret Service - According to Major David McNulty, the senior intelligence officer of the DCANG, his understanding is that “the information about the plane coming down the river” came from the Secret Service’s White House Joint Operations Center. [9/11 Commission, 3/11/2004 pdf file] FAA personnel are also receiving similar information from the Secret Service. At 10:32, an FAA employee tells John White, a manager at the FAA’s Herndon Command Center, “Secret Service is reporting one unknown eight miles out, flying inbound.” Two minutes later, this employee says they are “[t]rying to tell [the] Secret Service about [Flight] 93,” because the Secret Service is “a little bit behind, still getting reports.” They then tell White, “Secret Service is saying the aircraft they are talking is coming up the Potomac right now.” [9/11 Commission, 11/4/2003] Fire and rescue workers are evacuated away from the Pentagon site around this time, in response to a report from the FBI of a hijacked aircraft flying toward Washington (see (10:15 a.m.-10:38 a.m.) September 11, 2001). This may be the same alleged plane that the DCANG and FAA learn of. [US Department of Health and Human Services, 7/2002, pp. A30 pdf file; Fire Engineering, 11/2002]
Aircraft Supposedly a Helicopter - The incoming aircraft is apparently a false alarm. [9/11 Commission, 8/28/2003] After searching for it, Hutchison will be instructed to fly back toward Washington because, he will say, “the plane had been lost.” [9/11 Commission, 2/27/2004] According to a 9/11 Commission memorandum, “FAA tapes and transcripts” reveal the aircraft to be “an Army National Guard helicopter based out of Davison Field, Fort Belvoir, Virginia, which had become isolated in Maryland as events unfolded and which wanted to return to its home field.” [9/11 Commission, 3/11/2004 pdf file]
Secret Service Thinks Plane Crashed at Camp David - However, at 10:36, the FAA employee relays that the “Secret Service is saying they believe United 93 hit Camp David.” Seconds later, they add that the Secret Service is “confirming that UA 93 did go into Camp David.” [9/11 Commission, 11/4/2003] Even President Bush is given an incorrect report of a plane going down near Camp David around this time (see (10:37 a.m.-11:09 a.m.) September 11, 2001). [Sammon, 2002, pp. 108] So this erroneous information may be what leads to Hutchison being informed that the aircraft he was sent after has been lost. [9/11 Commission, 2/27/2004]

The FAA allows “military and law enforcement flights to resume (and some flights that the FAA can’t reveal that were already airborne).” All civilian, military, and law enforcement flights were ordered at 9:26 a.m. to land as soon as reasonably possible. [Time, 9/14/2001] Civilian flights remain banned until September 13. Note that the C-130 cargo plane that witnessed the Flight 77 crash (see 9.36 a.m. September 11, 2001) and which came upon the Flight 93 crash site (see 10:08 a.m. September 11, 2001) right after it had crashed was apparently not subject to the grounding order issued about an hour earlier.

The press incorrectly reports that an airliner has crashed on or near Camp David. [Daily Record (Baltimore), 9/12/2001; US Department of Transportation, 3/2002] Camp David is the presidential retreat, located about 70 miles north of Washington, DC, in the Catoctin Mountains of Maryland. [Federation of American Scientists, 10/2/2000; Associated Press, 7/30/2007] On Air Force One, at 10:37, White House chief of staff Andrew Card relays to the president the incorrect report of the crash. [Sammon, 2002, pp. 108] At around 11:09, CBS News reports that “a plane apparently has crashed at or near Camp David.” [Broadcasting and Cable, 8/26/2002] An early article by Forbes states, “There are reports of a fourth airliner [having] been brought down near Camp David… by US military fighters.” [Forbes, 9/11/2001] And an early report by the Northwestern Chronicle similarly states, “Air Force officials say an airliner has been forced down by F-16 fighter jets near Camp David.” [Northwestern Chronicle, 9/11/2001] Theresa Hahn, the catering manager for a restaurant in the Camp David area, hears the erroneous report. She subsequently describes, “Lots of fire trucks were on the road and no one can get up there.” But J. Mel Poole, the Catoctin Mountain Park superintendent, states there has been “no crash at Camp David.” [Daily Record (Baltimore), 9/12/2001] At some point, the FAA calls the military to confirm the crash, and is reassured that no crash occurred at Camp David. [Freni, 2003, pp. 42] The actual Flight 93 crash site is about 85 miles northwest of Camp David. [PBS, 9/11/2001] The Secret Service reportedly tells the White House that Flight 93 may have been on a course for Camp David. [Pittsburgh Channel, 9/11/2001] And, following a military briefing, Representative James Moran (D-VA) tells reporters that Flight 93 was apparently heading for Camp David. [Associated Press, 9/11/2001; Wall Street Journal, 9/12/2001] (However, the 9/11 Commission will later state that its intended target was either the White House or the Capitol building. [9/11 Commission, 7/24/2004, pp. 14] ) The source of the incorrect report of the Camp David crash is unclear. However, when the FAA’s Washington Center first informed NEADS that Flight 93 had crashed, at 10:15, it simply reported that it had gone down “somewhere up northeast of Camp David” (see 10:15 a.m. September 11, 2001), so this may have created some of the confusion. [Vanity Fair, 8/1/2006] There are also numerous false reports of terrorist attacks having taken place in Washington, DC around this time (see (Between 9:50-10:40 a.m.) September 11, 2001). Some commentators make the connection that the 9/11 attacks come 23 years after the signing of the Camp David accords—a peace agreement between Israel and Egypt—on September 17, 1978. [Forbes, 9/11/2001; Village Voice, 9/11/2001; Daily Record (Baltimore), 9/12/2001] WCBS reports, “[T]here is speculation that perhaps, perhaps, this may be in retaliation for those accords.” [Broadcasting and Cable, 8/26/2002]

Two F-16 fighters take off from Hancock Field Air National Guard Base, near Syracuse, NY. The fighters belong to the 174th Fighter Wing, a unit of the New York Air National Guard. A commander from Syracuse had called NORAD’s Northeast Air Defense Sector (NEADS) offering to help earlier in the morning (see (After 9:03 a.m.) September 11, 2001). Although at that time they’d promised: “Give me 30 minutes and I’ll have heat-seeker [missiles]. Give me an hour and I can give you slammers,” the fighters now launching have bullets but no missiles. [Post-Standard (Syracuse), 9/12/2001; Aviation Week and Space Technology, 6/3/2002; Post-Standard (Syracuse), 10/18/2002] The Hancock pilots are ordered to “Identify all aircraft… Intercept them. Tell them to land. ‘Engage’ them if they [don’t].” [Post-Standard (Syracuse), 9/25/2001] Also at some time this morning, following the attacks, 174th FW officials form a command center to monitor the situation across the US. [Post-Standard (Syracuse), 9/11/2001; Post-Standard (Syracuse), 9/12/2001] A hundred of the 174th FW’s staff have spent the last month deployed to Saudi Arabia and are due back this afternoon. However, they are diverted to Canada and arrive back at the base later in the week (see Mid-August-September 11, 2001).

At the NORAD operations center in Cheyenne Mountain, Colorado, NORAD commander in chief, General Ralph Eberhart, orders a limited version of a little known plan to clear the skies and give the military control over US airspace. [Aviation Week and Space Technology, 6/3/2002; 9/11 Commission, 6/17/2004] The plan, Security Control of Air Traffic and Navigation Aids (SCATANA), was developed in the 1960s as a way to clear airspace above the US and off the US coast in the event of a confirmed warning of a nuclear attack by the Soviet Union. Once it is activated a wartime air traffic priority list is established, allowing essential aircraft and personnel to use the airspace. Among others, this list includes the US president, essential national security staff, aircraft involved in continental defense missions, and airborne command posts. [Schwartz, 1998]
Eberhart Suggests Limited Version of Plan - Eberhart and his staff suggest implementing the limited version of SCATANA over the air threat conference call. Transportation Secretary Norman Mineta immediately concurs. [Aviation Week and Space Technology, 6/3/2002; Filson, 2003, pp. 73] Unlike a full SCATANA, this modified version allows ground navigation aids to stay on, for the benefit of aircraft that are still airborne. Under the plan, for about the next three days all flights other than military, law enforcement, fire fighters, and medevac, will require approval from the national Defense Department/FAA Air Traffic Services Cell, located within the FAA’s Herndon Command Center. [Bulletin of the Atomic Scientists, 11/2001; Aviation Week and Space Technology, 6/10/2002; 9/11 Commission, 6/17/2004] Notice is sent out to all civil and military air traffic control facilities, informing them that the skies now officially belong to NORAD. [Spencer, 2008, pp. 269]
Order Supposedly Made Late Due to Safety Concerns - The SCATANA order is issued over an hour after the FAA ordered all planes down (see (9:45 a.m.) September 11, 2001), and after at least three-quarters of them have already landed. [USA Today, 8/13/2002] Eberhart will later say the delay is due to safety concerns, because NORAD would have been unable to control US airspace—with over 4,000 planes airborne at the time of the attacks—with its radar capabilities. [9/11 Commission, 6/17/2004] Defense Week magazine will suggest SCATANA is not implemented until even later, at around 2:00 p.m. It says NORAD issues a “notice to airmen” implementing the modified version of SCATANA about five hours after Flight 11 hit the World Trade Center.

Passengers and crew members on board Delta Air Lines Flight 1989, which was wrongly suspected to have been hijacked, are finally allowed to get off their plane and are taken to be interviewed by the FBI. [Federal Aviation Administration, 9/16/2001; Federal Aviation Administration, 9/17/2001 pdf file; WKYC, 9/11/2006] Delta 1989 made an emergency landing at Cleveland Hopkins Airport in Ohio after FAA and military personnel mistakenly thought it was hijacked and might have a bomb on board (see (10:18 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 27-28; WKYC, 9/11/2006; Spencer, 2008, pp. 167-169] The plane was directed to a remote part of the airport, far away from the terminal, and the pilots were told not to allow passengers off.
No Evidence of Hijacking or Bomb - At 11:28 a.m., Cleveland Airport’s air traffic manager calls city officials and says he has no apparent reason to believe Delta 1989 has been hijacked, and he does not have any specific bomb threats. He says he has just received clearance from the FAA headquarters, which told him the airport had no reason to hold the aircraft unless city officials have other information from the FBI. [Federal Aviation Administration, 9/16/2001; Spencer, 2008, pp. 229]
SWAT Team and FBI Approach Plane - Delta 1989’s pilots, Captain Paul Werner and First Officer David Dunlap, are finally informed that the Cleveland Police SWAT (special weapons and tactics) team and a team of FBI agents are coming out to their aircraft. While the FBI agents approach the plane, the SWAT team takes up a position about 50 yards behind it. Lt. Bernie Barabas, the leader of the SWAT team, will later recall, “If there had been some sort of problem and this turned into a situation where this was a live hijacking, or if they started killing Americans, we were going to act.”
SWAT Team Sees Pilot with Bloodied Face - Suspicion is aroused when Werner accidentally knocks his head and cuts it while returning to his seat, after going to the cabin to speak to the plane’s passengers. The members of the SWAT team outside are perplexed when they see him leaning out of the window to give the “all clear” signal, with blood running down his face. They then board the plane. [WKYC, 9/11/2006; Spencer, 2008, pp. 270]
Passengers Taken off Plane - By 11:34 a.m., according to an FAA chronology, the FBI has commenced a controlled debarkation of Delta 1989. [Federal Aviation Administration, 9/17/2001 pdf file] The FBI agents slowly and carefully remove the passengers in small groups. [WKYC, 9/11/2006] According to some accounts, there are 78 people on the plane. [Associated Press, 9/11/2001; Federal Aviation Administration, 9/16/2001] But other accounts say there are about 200 on it. [Associated Press, 9/11/2001; Newsnet 5, 9/11/2001; WCPN, 9/12/2001] The FBI then instructs everyone that has got off to gather their belongings and line them up on the tarmac. [Spencer, 2008, pp. 270] Every piece of luggage and carry-on baggage will be opened and examined by security agents. [WKYC, 9/11/2006] Bomb-sniffing dogs board the aircraft, which is then searched, but no explosives will be found.
Passengers Taken Away and Interviewed - The SWAT team gathers the plane’s crew and passengers onto nearby buses. [Associated Press, 9/11/2001; Spencer, 2008, pp. 271] According to a timeline provided by the Cleveland Airport air traffic control tower, at 12:23 p.m. the passengers are taken to the Federal Facilities Building, located on the opposite side of the airfield to the terminal, where they are debriefed by the FBI. [Federal Aviation Administration, 9/16/2001] But the Associated Press will report that they are taken to a nearby NASA facility, presumably the Glenn Research Center, which is located next to the Cleveland airport. [Associated Press, 9/11/2001; National Journal's Technology Daily, 11/27/2002] After being interviewed separately by FBI agents, the passengers will be put up at a local Holiday Inn.

[Source: CBC]Air Force One, with President Bush on board, lands at Offutt Air Force Base near Omaha, Nebraska, accompanied by two F-16 fighter jets. [Salon, 9/12/2001; Bamford, 2004, pp. 89; 9/11 Commission, 7/24/2004, pp. 326] Offutt is the home of the US Strategic Command (Stratcom), which controls America’s nuclear weapons. [Associated Press, 9/11/2001; US Air Force, 9/6/2011] The large base is one of the most heavily defended in the US. [Daily Telegraph, 12/16/2001] Personnel there were told earlier in the day that the president might come to Offutt during the crisis but they only received confirmation that he would be landing at the base about 20 to 30 minutes ago. [Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/8/2002; Omaha World-Herald, 9/9/2016] They have, however, taken the initiative to start preparing for his arrival. “There were pretty wide-scale preparations going on anticipating that the president might come, without knowing for sure, even before we got notice that he was coming,” Admiral Richard Mies, commander in chief of Stratcom, will later recall. “We’d started to evacuate the main quarters that could be used for VIPs and install some of the protection there that’d be needed in case [Bush] needed to spend the night,” Mies will say. [NET News, 12/27/2011; Politico Magazine, 9/9/2016] Journalists on Air Force One were not told they would be landing at Offutt.

A US Airways airliner.A US Airways airliner. [Source: Public domain]A US Airways plane that is flying to the United States from Madrid, Spain, is incorrectly suspected of being hijacked. [Federal Aviation Administration, 9/11/2001; White House, 10/24/2001] It is stated over an FAA teleconference that the White House has reported this suspicious aircraft, which is heading to Philadelphia International Airport, and the military is scrambling fighter jets in response to it. [Federal Aviation Administration, 1/2/2002] NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the plane by US Customs and the FBI, according to a NORAD representative on the Pentagon’s air threat conference call (see 9:37 a.m.-9:39 a.m. September 11, 2001). NORAD has been unable to locate the aircraft on radar, according to the NORAD representative. [US Department of Defense, 9/11/2001] Accounts conflict over whether the plane is US Airways Flight 930 or Flight 937. [Federal Aviation Administration, 9/2001; Federal Aviation Administration, 9/11/2001; Federal Aviation Administration, 1/2/2002]
Plane Is Reportedly Transmitting the Hijack Signal - Lewis Libby, Vice President Dick Cheney’s chief of staff, who is in the Presidential Emergency Operations Center (PEOC) below the White House, will later recall that when those in the PEOC learn of the suspect flight, “we got word that it was only 30 minutes or so outside of US airspace.” According to Libby, the plane’s transponder is transmitting the code for a hijacking: He will say it is reported that the flight has been “showing hijacking through some electronic signal.” [White House, 11/14/2001] However, according to the NORAD representative on the air threat conference call, the plane’s transponder has not been “squawking” the code for a hijacking. “We do not have squawk indication at this point,” he has said.
Plane Is Reportedly Diverted to Pittsburgh - An FAA representative on the air threat conference call apparently says an e-mail has been sent from the suspicious aircraft, stating that the plane is being diverted to Pittsburgh, although the FAA representative’s communications are distorted and therefore unclear. [US Department of Defense, 9/11/2001]
President Says Fighters Can Shoot Down the Plane - President Bush discusses the suspicious US Airways flight with Secretary of Defense Donald Rumsfeld over the air threat conference call after landing at Offutt Air Force Base in Nebraska (see 2:50 p.m. September 11, 2001) and Major General Larry Arnold, the commander of the Continental United States NORAD Region (CONR), listens in. [Filson, 2003, pp. 87-88] Rumsfeld wants Bush to confirm that fighters are authorized to shoot down the plane if it is considered a threat to a city in the US. “The reason I called… was just to verify that your authorization for the use of force would apply as well in this situation,” he says. Bush replies, “It does, but let us make sure that the fighters and you on the ground get all the facts.” [US Department of Defense, 9/11/2001]
Plane Is on the Ground in Spain - After a time, it will be found that the plane is not a threat and is on the ground in Spain. Arnold will be called by Colonel Robert Marr, the battle commander at NEADS, and told, “We just talked to the airline and that aircraft is back on the ground in Madrid.” [Filson, 2003, pp. 88] According to Libby, “It turned out that, I think, it was only 35 minutes out of Spanish airspace, not out of our airspace.” [White House, 11/14/2001] Reggie Settles, the FAA representative at NORAD’s Cheyenne Mountain Operations Center in Colorado, will be informed by US Airways that Flight 937 in fact never existed. However, he will be told, there is a US Airways Flight 911, which “took off from Madrid,” but “has turned back and returned to Madrid,” and “is not en route to the United States.” [US Department of Defense, 9/11/2001]
President Decides to Leave Offutt after the Concerns Are Resolved - After he learns that the suspicious plane is back in Spain, Arnold will pick up the hot line and tell Bush: “Mr. President, this is the CONR commander.… No problem with Madrid.” According to Arnold, Bush will reply, “Okay, then I’m getting airborne.” [Filson, 2003, pp. 88] Bush will take off from Offutt aboard Air Force One at around 4:30 p.m. (see (4:33 p.m.) September 11, 2001).

Carl Levin.Carl Levin. [Source: Publicity photo]Air Force General Richard Myers is questioned about the US military’s response to the 9/11 attacks when he appears before the Senate Armed Services Committee for his confirmation hearing as chairman of the Joint Chiefs of Staff, but his answers are vague and confused, and he claims, incorrectly, that no fighter jets were scrambled in response to the hijackings until after the Pentagon was hit. [Shenon, 2008, pp. 119; Farmer, 2009, pp. 241-243] Myers has been the vice chairman of the Joint Chiefs of Staff since March 2000. [US Air Force, 9/2005] With General Henry Shelton, the chairman of the Joint Chiefs of Staff, flying toward Europe on the morning of September 11 (see (8:50 a.m.-10:00 a.m.) September 11, 2001), he served as the acting chairman of the Joint Chiefs of Staff during the 9/11 attacks. [Myers, 2009, pp. 10; Shelton, Levinson, and McConnell, 2010, pp. 431-433]
Myers Says Fighters Were Only Scrambled after the Pentagon Attack - During the hearing, Senator Carl Levin (D-MI) asks if the Department of Defense was contacted by “the FAA or the FBI or any other agency” after the first two hijacked aircraft crashed into the World Trade Center, at 8:46 a.m. and 9:03 a.m. (see 8:46 a.m. September 11, 2001 and 9:03 a.m. September 11, 2001), but before 9:37 a.m., when the Pentagon was hit (see 9:37 a.m. September 11, 2001). Myers replies, “I don’t know the answer to that question.” Levin then asks if the military was “asked to take action against any specific aircraft” during the attacks. Myers answers, “When it became clear what the threat was, we did scramble fighter aircraft, AWACS, radar aircraft, and tanker aircraft to begin to establish orbits in case other aircraft showed up in the FAA system that were hijacked.” Myers elaborates later in the hearing, telling Senator Bill Nelson (D-FL): “[A]fter the second tower was hit, I spoke to the commander of NORAD, General [Ralph] Eberhart (see (9:37 a.m.) September 11, 2001). And at that point, I think the decision was at that point to start launching aircraft.” But he tells Levin that “to the best of my knowledge,” the order to scramble fighters was only given “after the Pentagon was struck.”
Flight 93 Was Not Shot Down, Myers Says - Myers addresses the military’s response to Flight 93, the fourth hijacked plane, which crashed in a field in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). He says: “[I]f my memory serves me… we had launched on the one that eventually crashed in Pennsylvania. I mean, we had gotten somebody close to it, as I recall.” However, he adds, “I’ll have to check that out.” When Levin mentions that there have been “statements that the aircraft that crashed in Pennsylvania was shot down,” Myers responds, “[T]he armed forces did not shoot down any aircraft.” He says, “[W]e never actually had to use force.” Although Myers appears unclear about when the North American Aerospace Defense Command (NORAD) launched fighters in response to the hijackings, he is more confident when he states: “At the time of the first impact on the World Trade Center, we stood up our Crisis Action Team. That was done immediately. So we stood it up. And we started talking to the federal agencies.” [US Congress, 9/13/2001]
NORAD and the 9/11 Commission Contradict Myers's Account - Myers’s claim that fighters were only launched in response to the hijackings after the Pentagon was hit will later be contradicted by the accounts of NORAD and the 9/11 Commission, which state that fighters were ordered to take off from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001) and from Langley Air Force Base in Virginia at 9:24 a.m. (see 9:24 a.m. September 11, 2001). [North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 20, 27] The 9/11 Commission will also contradict Myers’s claim that the military launched fighters in response to Flight 93 and “had gotten somebody close to it.” “By the time the military learned about the flight,” the 9/11 Commission Report will state, “it had crashed.” [9/11 Commission, 7/24/2004, pp. 34]
Myers's Testimony Prompts Criticism in the Media - Journalist and author Philip Shenon will question why Myers, a veteran Air Force fighter pilot, would give such an inaccurate account of the military’s response to the 9/11 attacks during the hearing. “It seemed obvious that Myers, of all people at the Pentagon, would want to know—would demand to know—how jet fighters under NORAD’s control had responded on the morning of September 11 to the threat in the skies,” he will write. [US Congress, 9/13/2001; Shenon, 2008, pp. 119] John Farmer, the senior counsel to the 9/11 Commission, will comment that “Myers’s evident confusion about precisely what had occurred prompted criticism in the media and a quick, if contradictory, response from the administration.” [Farmer, 2009, pp. 243] Major General Paul Weaver, director of the Air National Guard, will provide a more detailed account of the military’s response to the hijackings in an “impromptu hallway interview” at the Pentagon on September 14 (see September 14, 2001). [Dallas Morning News, 9/14/2001] And four days later, NORAD will release a timeline of its response to the hijackings (see September 18, 2001). [North American Aerospace Defense Command, 9/18/2001]

Major General Paul Weaver, director of the Air National Guard, provides reporters with details of the 9/11 attacks and the US military’s response to the hijackings. Speaking at the Pentagon, Weaver gives reporters a detailed account of what happened on September 11. He says Air National Guard planes responded to the hijackings on orders from NORAD’s Northeast Air Defense Sector (NEADS), which was alerted to the hijackings by the Federal Aviation Administration (FAA).
Fighters Took Off Too Late to Catch Flight 175 - Weaver says that at 8:53 a.m., seven minutes after Flight 11 crashed into the North Tower of the World Trade Center (see 8:46 a.m. September 11, 2001), two F-15 fighter jets took off from Otis Air National Guard Base in Cape Cod, Massachusetts, in pursuit of Flight 175, the second plane to be hijacked (see 8:46 a.m. September 11, 2001 and 8:53 a.m. September 11, 2001). However, Weaver says, the FAA had only told NEADS that “there was an airplane that had a problem,” and at that time it was unclear if Flight 175 had been hijacked. He says that although the fighters flew at over 500 miles per hour, they were unable to catch up with Flight 175 before it hit the South Tower of the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001).
More Fighters Were Launched Just before Pentagon Was Hit - Weaver says Flight 77, the third aircraft to be hijacked, flew west for 45 minutes and then turned east, and its transponder was turned off. He does not claim that the military received notice that it had been hijacked, but says NEADS scrambled F-16 fighters that were on alert at Langley Air Force Base in Virginia at 9:35 a.m. (see 9:24 a.m. September 11, 2001 and (9:25 a.m.-9:30 a.m.) September 11, 2001). Two minutes later, at 9:37 a.m., the Pentagon was hit (see 9:37 a.m. September 11, 2001). The F-16s, he says, subsequently remained on patrol over the Pentagon.
No Fighters Took Off to Intercept Flight 93 - Weaver says no fighters were scrambled to chase after Flight 93, the fourth hijacked plane, which crashed in a field in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). “There was no notification for us to launch airplanes,” he tells the reporters. “We weren’t even close.” [Dallas Morning News, 9/14/2001; Farmer, 2009, pp. 244] (However, also on this day, Deputy Defense Secretary Paul Wolfowitz contradicts Weaver’s claim. He tells PBS’s NewsHour, “[W]e were already tracking in on that plane that crashed in Pennsylvania,” and adds, “[T]he Air Force was in a position to do so [i.e. shoot Flight 93 down] if we had had to.” [NewsHour with Jim Lehrer, 9/14/2001; Farmer, 2009, pp. 245] ) Weaver says that even if fighters had caught up with the hijacked planes, they may have been unable to stop them reaching their targets. “You’re not going to get an American pilot shooting down an American airliner,” he says. “We don’t have permission to do that.” According to Weaver, only the president can issue an order to shoot down an American airliner. [Dallas Morning News, 9/14/2001]
Weaver's Account Is the 'Most Accurate' Prior to the 9/11 Commission's Investigation - The account he gives to reporters today, according to John Farmer, the senior counsel to the 9/11 Commission, will be “the last public statement uttered by General Weaver on the subject and proved to be the most accurate account of events issued until the 9/11 Commission’s investigation.” [Farmer, 2009, pp. 245] Apparently after Weaver issues his statement to the reporters, an Air Force spokesman, speaking on condition of anonymity, adds that no regular Air Force planes were scrambled during the 9/11 attacks, “because continental air defense is the mission of the Air National Guard.” He says regular Air Force fighters “have air superiority as their mission,” which means they train “to deploy somewhere where we are engaged in hostile action and secure the skies.” These fighters, according to the spokesman, “ordinarily are not ready to fly on short notice and their pilots are not on standby to defend the United States.” [Dallas Morning News, 9/14/2001]
Pentagon Has Been Slow to Answer Questions about Response to Hijackings - The Washington Post will comment, “Questions about the time it took US military planes to respond to the threat of several hijacked aircraft speeding toward the nation’s financial and military centers have dogged the Pentagon since the attacks.” It will add, “Top Pentagon officials have been slow to respond to press inquiries for a timeline that would establish the exact times that civil aviation authorities became aware of the hijackings, when US military commanders were notified, and when US fighter jets took to the air.” [Washington Post, 9/15/2001] The previous day, Air Force General Richard Myers was questioned about the military’s response to the attacks before the Senate Armed Services Committee, but his answers were vague and confused (see September 13, 2001). [US Congress, 9/13/2001; Farmer, 2009, pp. 241-242] NORAD will release its own timeline of the events of September 11 and its response to the hijackings on September 18 (see September 18, 2001).

The Federal Aviation Administration (FAA) produces a chronology of the events of September 11, which it uses when it briefs the White House today, but the document fails to mention when NORAD’s Northeast Air Defense Sector (NEADS) was alerted to two of the hijacked planes. The FAA’s chronology, titled “Summary of Air Traffic Hijack Events,” incorporates “information contained in the NEADS logs, which had been forwarded, and on transcripts obtained from the FAA’s Cleveland Center, among others,” according to John Farmer, the senior counsel to the 9/11 Commission.
Document Includes Notification Times for First Two Hijacked Flights - The chronology refers “accurately to the times shown in NEADS logs for the initial notifications from FAA about the hijacking of American 11 and the possible hijacking of United 175,” according to the 9/11 Commission. It gives 8:40 a.m. as the time at which the FAA alerted NEADS to Flight 11, the first plane to be hijacked (see (8:37 a.m.) September 11, 2001), and 9:05 a.m. as the time when the FAA alerted NEADS to Flight 175, the second plane to be hijacked (see (9:03 a.m.) September 11, 2001). However, it makes no mention of when the FAA alerted NEADS to Flight 77 and Flight 93, the third and fourth planes to be hijacked. The FAA’s omission of these two notification times is “suspicious,” according to the 9/11 Commission, “because these are the two flights where FAA’s notification to NEADS was significantly delayed.”
Document Omits Notification Times for Flights 77 and 93 - The chronology, as Farmer will later point out, “makes no mention… of the notification to NEADS at 9:33 that American 77 was ‘lost’ (see 9:34 a.m. September 11, 2001) or of the notification to NEADS at 9:34 of an unidentified large plane six miles southwest of the White House (see 9:36 a.m. September 11, 2001), both of which are in the NEADS logs that the FAA reviewed” when it was putting together the timeline. It also fails to mention the call made by the FAA’s Cleveland Center to NEADS in which, at 10:07 a.m., the caller alerted NEADS to Flight 93 and said there was a “bomb on board” the plane (see 10:05 a.m.-10:08 a.m. September 11, 2001), even though this information was also “duly noted in the NEADS logs” that the FAA has reviewed.
Chronology Omits Other Key Information - The chronology, Farmer will write, reflects “a time at which the FAA was notified that the Otis [Air National Guard Base] fighters were scrambled” in response to the hijacking of Flight 11 (see 8:46 a.m. September 11, 2001), but it gives “no account of the scramble of the fighters from Langley Air Force Base” (see 9:24 a.m. September 11, 2001). It also fails to mention the report that NEADS received after Flight 11 crashed, in which it was incorrectly told the plane was still airborne and heading toward Washington, DC (see 9:21 a.m. September 11, 2001). Despite lacking information about the times when the FAA alerted NEADS to Flights 77 and 93, the FAA’s chronology is one of the documents used to brief the White House about the 9/11 attacks today (see September 17, 2001).
Investigators Were Told to Determine Exact Notification Times - The chronology is the product of investigations that began promptly in response to the 9/11 attacks. According to senior FAA officials, FAA Administrator Jane Garvey and Deputy Administrator Monte Belger “instructed a group of FAA employees (an ‘after-action group’) to reconstruct the events of 9/11.” This group, according to the 9/11 Commission, “began its work immediately after 9/11 and reviewed tape recordings, transcripts, handwritten notes, logs, and other documents in an effort to create an FAA chronology of events.” The group, according to one witness, “was specifically asked to determine exactly when the FAA notified the military that each of the four planes had been hijacked,” and “[s]everal people worked on determining correct times for FAA notifications to the military.” [Federal Aviation Administration, 9/17/2001 pdf file; 9/11 Commission, 7/29/2004; Farmer, 2009, pp. 245-247] NORAD will release a timeline of the events of September 11 and its response to the attacks a day after the FAA chronology is published (see September 18, 2001).

The North American Aerospace Defense Command (NORAD) releases a chronology of the events of September 11 and its response to the terrorist attacks that day, but the accuracy of this account will later be challenged by the 9/11 Commission. [North American Aerospace Defense Command, 9/18/2001; 9/11 Commission, 7/24/2004, pp. 34; 9/11 Commission, 7/29/2004]
NORAD Learned of First Hijackings Too Late to Defend the WTC - The chronology provides the times at which NORAD’s Northeast Air Defense Sector (NEADS) was alerted to the hijackings and when fighter jets were scrambled in response to the hijackings. It states that the Federal Aviation Administration (FAA) notified NEADS about Flight 11, the first hijacked aircraft, at 8:40 a.m. In response, the order was given to scramble two F-15 fighters from Otis Air National Guard Base in Cape Cod, Massachusetts, at 8:46 a.m. (see 8:46 a.m. September 11, 2001), the same time that Flight 11 crashed into the World Trade Center (see 8:46 a.m. September 11, 2001), and the fighters were airborne at 8:52 a.m. (see 8:53 a.m. September 11, 2001). The FAA notified NEADS about Flight 175, the second hijacked aircraft, at 8:43 a.m., according to the chronology. When Flight 175 crashed into the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001), the chronology states, the Otis fighters were 71 miles away from New York.
Fighters Were Scrambled in Response to Flight 77 Hijacking - NEADS was alerted to Flight 77, the third hijacked aircraft, at 9:24 a.m., according to the chronology. In response, the order was given to scramble two F-16 fighters from Langley Air Force Base in Virginia (see 9:24 a.m. September 11, 2001) and these were airborne at 9:30 a.m. (see (9:25 a.m.-9:30 a.m.) September 11, 2001). But the F-16s were 105 miles from the Pentagon when it was hit at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Regarding the fourth hijacked aircraft, Flight 93, the chronology gives “N/A” as the time the FAA alerted NEADS, but it also states that the FAA and NEADS discussed the flight on “a line of open communication.” At 10:03 a.m., when Flight 93 crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001), the chronology states, the F-16s launched from Langley Air Force Base in response to the hijacking of Flight 77 were “in place to protect DC.” [North American Aerospace Defense Command, 9/18/2001]
9/11 Commission Disputes NORAD's Account - The 9/11 Commission Report, released in 2004, will highlight what it says are inaccuracies in NORAD’s timeline of the events of September 11. It will state that NORAD’s claim that NEADS was alerted to Flight 77 at 9:24 a.m. was incorrect. The notice NEADS received at that time, according to the report, was the incorrect claim that Flight 11 “had not hit the World Trade Center and was heading for Washington, DC” (see 9:21 a.m. September 11, 2001). “NEADS never received notice that American 77 was hijacked,” the report will state. “It was notified at 9:34 that American 77 was lost (see 9:34 a.m. September 11, 2001). Then, minutes later, NEADS was told that an unknown plane was six miles southwest of the White House” (see 9:36 a.m. September 11, 2001). The report will state that NORAD’s claim that the Langley fighters were scrambled in response to the notification about Flight 77 is also incorrect. Instead, it will state, the fighters were scrambled in response to the incorrect report that Flight 11 was still airborne and heading south. [9/11 Commission, 7/24/2004, pp. 34]
9/11 Commission Disputes NORAD's Account regarding Flights 175 and 93 - Furthermore, whereas NORAD’s chronology claims that NEADS discussed Flight 93 with the FAA on “a line of open communication,” the 9/11 Commission Report will state that NEADS “first received a call about United 93 from the military liaison at [the FAA’s] Cleveland Center at 10:07,” by which time the plane “had already crashed” (see 10:05 a.m.-10:08 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 30] And while NORAD states that the FAA notified NEADS about Flight 175 at 8:43 a.m., according to the report, the first notification came “in a phone call from [the FAA’s] New York Center to NEADS at 9:03” (see (9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 23]
Military Has Been Slow to Provide Details of Its Response on September 11 - US military officials, according to the Washington Post, “have been slow to respond to press inquiries for a timeline that would establish the exact times that civil aviation authorities became aware of the hijackings, when US military commanders were notified, and when US fighter jets took to the air.” [Washington Post, 9/15/2001] On September 13, Air Force General Richard Myers was questioned about the military’s response to the 9/11 attacks before the Senate Armed Services Committee, but his answers were vague and confused (see September 13, 2001). [US Congress, 9/13/2001; Farmer, 2009, pp. 241-242] A day later, Major General Paul Weaver, director of the Air National Guard, provided reporters with details of the military’s response to the hijackings in an “impromptu hallway interview” at the Pentagon (see September 14, 2001).

Senate, 10/25/2001; 9/11 Commission, 7/29/2004; Farmer, 2009, pp. 248] Eberhart was at NORAD headquarters at Peterson Air Force Base, Colorado, and then went to NORAD’s operations center in Cheyenne Mountain when the 9/11 attacks were taking place. [9/11 Commission, 3/1/2004 pdf file; 9/11 Commission, 3/1/2004] NORAD released a timeline of its response to the hijackings on September 18 (see September 18, 2001) and Eberhart’s testimony is consistent with that account. [North American Aerospace Defense Command, 9/18/2001]
Eberhart Says Fighters Were Scrambled in Response to First Hijacking - During the hearing, Eberhart tells Senator Wayne Allard (R-CO) that after the Federal Aviation Administration (FAA) alerted NORAD to the first hijacking, of Flight 11 (see (8:37 a.m.) September 11, 2001), NORAD ordered two F-15 fighter jets to take off from Otis Air National Guard Base in Cape Cod, Massachusetts (see 8:46 a.m. September 11, 2001), “almost simultaneously to the first crash” at the World Trade Center (see 8:46 a.m. September 11, 2001). Eberhart says that after he learned a plane had hit the WTC, he was initially unsure if that plane was Flight 11. “I’m sitting there hoping that someone has made a mistake; there has been an accident; that this isn’t the hijacked airplane [that hit the WTC], because there is confusion,” he recalls. He says he was informed that “it was a light commuter airplane” that hit the WTC, although, he says, it “didn’t look like that was caused by a light commuter airplane.”
Fighters Didn't Have Enough Time to Stop Second Crash - Eberhart says the FAA notified NORAD that there was “a second hijacked plane”—referring to Flight 175—“somewhere in there,” but although the Otis fighters were “flying toward New York” after being scrambled, they were still eight minutes away from the city when Flight 175 crashed into the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “Tragically, there was just too much distance between Otis and New York City to get there in time,” Eberhart comments.
Eberhart Says NORAD Learned Flight 77 Was Hijacked before It Crashed - Eberhart says the first documented instance NORAD has of the FAA notifying it about Flight 77, the third aircraft to be hijacked, was at 9:24 a.m. After the hearing, in responses submitted for the record, Eberhart adds that the FAA notified NORAD’s Northeast Air Defense Sector (NEADS) that Flight 77 “was headed towards Washington, DC.” NEADS, he states, “then passed this information to NORAD’s Air Warning Center and Command Center in Cheyenne Mountain, and to the Continental US NORAD Region’s Regional Air Operations Center.”
Fighters Were Scrambled Too Late to Prevent the Pentagon Attack - Eberhart says NORAD launched two F-16 fighters from Langley Air Force Base in Virginia “as soon as” the FAA alerted it to the hijacking of Flight 77 (see 9:24 a.m. September 11, 2001). However, he says, these fighters were still “approximately 13 minutes away from Washington, DC, when that tragic crash [at the Pentagon] occurred.”
Eberhart Is Unaware of Reason for FAA's Delay in Contacting NORAD - Senator Carl Levin (D-MI) tells Eberhart: “The timeline that we’ve been given is that at 8:55 on September 11, American Airlines Flight 77 began turning east, away from its intended course. And at 9:10, Flight 77 was detected by the FAA radar over West Virginia heading east. That was after the two planes had struck the World Trade Center towers. Then 15 minutes later, at 9:25, the FAA notified NORAD that Flight 77 was headed toward Washington.” In light of this, he asks, “[D]o you know why it took 15 minutes for the FAA to notify NORAD?” Eberhart replies: “I do not know, sir, why it took that amount of time for FAA. I hate to say it, but you’ll have to ask FAA.” Senator John Warner (R-VA), who has an extensive military background, tells Eberhart he is “a little bit stunned that you don’t know why that delay occurred.” He continues, saying, “I would have thought by now all of you in this chain would have gone back, rehearsed these things, figured out what happened, what went wrong, so that we ensure it won’t happen again.” In his responses submitted for the record, Eberhart suggests possible reasons for the delay, stating that after the FAA lost radar contact with Flight 77, it “began to receive calls from outside agencies with reports of a possible downed aircraft. Additionally, the loss of radio contact with the aircraft added to the confusion.” Consequently, he states, “I believe the FAA was faced with conflicting information, which hindered them from making an accurate assessment of the actual location of the aircraft.”
Eberhart Says NORAD Was Following Flight 93 before It Crashed - Eberhart says NORAD was aware of the problems with Flight 93, the fourth hijacked plane, before it crashed in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). He tells Allard that the FAA “knew before it deviated its flight pattern” that Flight 93 “was hijacked.” He says NORAD had been “trying to decide, initially, if that flight was going to continue west and if there was some other target for that flight. Was it Chicago? Was it St. Louis? And what might we do to launch an aircraft to intercept it.” But he says that after the FAA reacquired Flight 93 on radar, NORAD thought the plane “was headed probably for Washington, DC, but maybe New York.” He says NORAD decided at that time to keep the Otis and Langley fighters in place over New York and Washington. If another suspicious plane was approaching, he says, “our intent was to go out and meet that aircraft and destroy it if we needed to, if it entered either Washington, DC, or New York City airspace.” However, in his responses submitted for the record, Eberhart states that the “data/log entries received by NORAD from the FAA [after September 11] do not show a time or entry indicating the FAA specifically notified the Pentagon that United Airlines Flight 93 was hijacked.” He also states that NORAD “did not notify” the National Military Command Center (NMCC) at the Pentagon that Flight 93 had been hijacked.
9/11 Commission Disputes Some of Eberhart's Claims - Several claims Eberhart makes in the hearing will be contradicted by evidence uncovered by the 9/11 Commission during its investigation of the terrorist attacks. Whereas Eberhart says the military was first notified about the hijacking of Flight 77 at 9:24 a.m. and implies that this notification prompted the scrambling of fighters from Langley Air Force Base, according to John Farmer, the senior counsel to the 9/11 Commission, “[T]he first notification regarding American 77 occurred at 9:34, when it was reported ‘lost’” (see 9:34 a.m. September 11, 2001). [US Congress. Senate, 10/25/2001; Farmer, 2009, pp. 248-254] The notice NEADS received at 9:24 a.m., according to the 9/11 Commission Report, was the incorrect claim that Flight 11 “had not hit the World Trade Center and was heading for Washington, DC” (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 34] Consequently, Farmer will write, “the scramble of the Langley fighters did occur as an immediate reaction to a notification about hijacking, but that notification was not, as [Eberhart’s] testimony implies, a report that American 77 was hijacked, but the report that American 11 was still airborne and heading for Washington.” And while Eberhart claims the FAA told NEADS that Flight 77 was heading toward Washington, according to Farmer: “The FAA never notified NEADS that American 77 was heading for Washington, DC. There is no such notification recorded on any tape or in any log maintained at NEADS or at NORAD.” Furthermore, while Eberhart claims the military was following Flight 93 on radar before it crashed and was in position to shoot it down if it approached Washington, Farmer will write that “in fact, NEADS never located United 93 on radar, because the plane had already crashed by the time NEADS was notified.” [Farmer, 2009, pp. 251, 254-255]

Joseph Trombino.Joseph Trombino. [Source: Family photo]An armored truck that was parked in the basement of the World Trade Center on the morning of 9/11 is discovered by recovery workers, who find that diamonds and bonds worth over a million dollars are inexplicably missing from it. The Brink’s armored truck was driven down to the underground receiving platform of the North Tower sometime before 8:46 a.m. on September 11, to deliver $14 million in cash. As well as this cash, the vehicle was carrying negotiable bonds and diamonds.
Driver Stayed with His Truck after Flight 11 Hit the WTC - Its driver, Joseph Trombino, waited while his three fellow guards dropped off the cash with some Bank of Nova Scotia guards, who put the money into canvas carts to be taken to a vault. Trombino was still in his vehicle when Flight 11 crashed into the North Tower, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). His fellow guards were subsequently evacuated from the tower. But instead of leaving, Trombino stayed with his vehicle, perhaps to protect the cargo or because he expected his colleagues to return. At 9:15 a.m., he called Brink’s and reported that a police officer had told him to move his truck because the tower was unstable. He also reported that the building was shaking and water was cascading down. He was killed when the North Tower collapsed, at 10:28 a.m. (see 10:28 a.m. September 11, 2001).
Recovery Workers Discover the Armored Truck - Now, over three months later, a recovery team unearths part of the roof of Trombino’s truck in the wreckage of the WTC. Sergeant Kevin Murphy of the Port Authority Police Department (PAPD) calls Lieutenant William Keegan, who is in charge of the PAPD’s nighttime rescue and recovery operation at Ground Zero, and tells him about the find. Keegan, in turn, contacts Brink’s to alert it to the discovery of one of its vehicles. Brink’s says it will send someone to the WTC site as soon as possible and mentions that the truck contains over a million dollars’ worth of valuables, comprising $250,000 in diamonds and $750,000 in negotiable bonds. The company also says the truck’s driver—Trombino—is still missing. Keegan then heads to the WTC site and a Brink’s supervisor also goes there.
Diamonds and Bonds Are Missing from the Truck - Once enough rubble has been removed to see inside the truck, Keegan and the other workers notice that the cab is empty. Keegan will later wonder if Trombino sought refuge under his truck when the Twin Towers collapsed, got into the back of it for safety, or left the vehicle and tried to get up to the street. Keegan wants to get into the back of the truck to remove the valuables from there. To get inside, the workers cut into a section of the roof with a circular saw and peel it back to create an opening. PAPD officer Tony Demeri is then lowered down through the hole. But after he carries out a full inspection, Demeri reports that the truck is empty, with no bonds or diamonds to be found. [New York Times, 9/17/2001; Chicago Tribune, 9/22/2001; Keegan and Davis, 2006, pp. 147-149] Trombino’s wife, Jean Trombino, will say in January 2002 that although her husband’s body has been recovered, she hasn’t been told where it was found. [New Jersey Star-Ledger, 1/2/2002] Brink’s will report in 2014 that the body was found near the water fountain between the Twin Towers, in the WTC plaza, along with Trombino’s messenger bag. [Brink's Blog, 9/10/2014] The canvas carts filled with the $14 million that Trombino delivered on September 11 will be discovered in the rubble of the WTC in February 2002. However, Keegan will write in 2006, “Neither the bonds nor the diamonds have ever been recovered.” [Keegan and Davis, 2006, pp. 149]

One of the key variables in the computer simulations used by the National Institute of Standards and Technology (NIST) (see (October 2002-October 2005)) to explain the WTC collapses is the speed of the aircraft that hit the towers. However, there is no consensus on how fast the planes were traveling. The first estimate was contained in an initial research paper by engineers Zdenek Bazant and Yong Zhou, who stated that the planes were traveling at 342 miles per hour. [Bazant and Zhou, 1/2002 pdf file] However, the Federal Emergency Management Agency (FEMA) and American Society of Civil Engineers (ASCE) report said that the plane that hit the North Tower was traveling at 470 miles per hour, whereas the plane that hit the South Tower was traveling at 590 miles per hour (see May 1, 2002). [Federal Emergency Management Agency, 5/1/2002, pp. 31] NIST initially estimates speeds of 435 miles per hour for the plane that hit the North Tower and 497 miles per hour for the plane that hit the South Tower. These estimates closely match figures produced by the Massachusetts Institute of Technology, which finds speeds of 429 miles per hour and 503 miles per hour for the two planes. However, NIST is dissatisfied with these results and does a second study, which finds speeds of 466 and 545 miles per hour. It then uses speeds of 472 and 570 miles per hour in its severe case model, on which its final report is based. In this model, the simulation of the planes traveling faster means greater damage to the towers’ structure, making them more unstable.

Matthys Levy.Matthys Levy. [Source: PBS]A report is made publicly available, which the Engineering News-Record calls the “most comprehensive study yet on the destruction of the World Trade Center.” The study was commissioned by WTC leaseholder Silverstein Properties Inc. to support a $7 billion insurance claim, and conducted by a team of engineers from several leading firms, including Weidlinger Associates, LZA Technology/Thornton-Tomasetti, and ARUPFire. It is intended to build on a previous study sponsored by FEMA (see May 1, 2002). The report’s findings are based on an analysis of original structural drawings, thousands of photos, and dozens of videos. Investigators used fire evaluation techniques and powerful computer software to simulate the condition of each tower at critical times between the planes’ impacts and the towers’ collapses. The earlier FEMA investigators had no access to such computer modeling. Matthys Levy, the chairman of Weidlinger Associates and one of the engineers on the study team, says, “The buildings had tremendous reserve capacity and that was reflected in all of the elements we analyzed. In fact, because there were so much excess capacity, the columns even in the impact floors did not buckle immediately, but failed as the result of the fire.” The report states that failure of the WTC’s steel floor supports (“trusses”) did not contribute to the collapses. Instead, the collapses were caused by the failure of steel structural columns that were either destroyed when the planes hit or lost fireproofing, leaving them vulnerable to the weakening effects of the ensuing fires. It says that debris and dust distributed by the plane crashes inhibited the fires, such that the average air temperatures on the impact floors were between 400 and 700°C (750-1,300°F): significantly lower than those associated with typical “fully developed” office fires. However, says Matthys Levy, “By the time the temperature inside the buildings reached 400 degrees, the steel would have lost approximately 50% of its strength. Eventually, gravity took over and the towers began to fall.” Then, according to the analysis led by researchers from LZA Technology/Thornton-Tomasetti, “Once collapse initiated in each tower, essentially all of the interior structure of the tower fell straight down with floors pancaking on top of one another. The network of perimeter steel columns and spandrels acted like a chute to funnel the interior contents into the tower footprint.” According to the computer simulations, the damage to the South Tower’s steel core columns was so severe that the tower should have collapsed immediately after the plane hit. Civil engineer John Osteraas says this incorrect result casts doubt upon some of the study’s predictions. The report concludes that the collapse of the South Tower did not cause or contribute to the subsequent collapse of the North Tower, thus supporting Silverstein Properties’ claim that the terrorist attack represented two occurrences, entitling it to two $3.5 billion insurance policy limits. A separate study commissioned by the insurers contradicts this (see October 23, 2002). The Silverstein report apparently does not examine the collapse of WTC Building 7, a 47-story skyscraper that also collapsed on 9/11 (see (5:20 p.m.) September 11, 2001). It has been passed on to the National Institute of Standards and Technology (NIST), which is undertaking its own investigation of the WTC collapses (see August 21, 2002).

The 9/11 Commission holds a public hearing at which it takes testimony from military officials about the timeline of events on the day of 9/11. The key witness is retired Air Force General Larry Arnold, who commanded NORAD’s Continental US Region on the day of 9/11. Under questioning from commissioner Richard Ben-Veniste, Arnold says, “I believe that to be a fact: that 9:24 was the first time that we had been advised of American 77 as a possible hijacked airplane.” However, the Commission will later conclude that the military was not notified of the hijacking at this time, although it had been mistakenly advised Flight 11 was inbound to Washington three minutes previously (see 9:21 a.m. September 11, 2001 and (9:24 a.m.) September 11, 2001). Arnold adds that if the military was slow in responding to Flight 77, it was because “our focus—you have got to remember that there’s a lot of other things going on simultaneously here—was on United 93.” However, Flight 93 was not hijacked until a few minutes after 9:24 (see (9:28 a.m.) September 11, 2001). Arnold adds: “It was our intent to intercept United Flight 93. And in fact, my own staff, we were orbiting now over Washington, DC, by this time, and I was personally anxious to see what 93 was going to do, and our intent was to intercept it.” However, the Commission will later conclude that the military did not learn that Flight 93 had been hijacked until around 10:00 a.m. (see 10:03 a.m. September 11, 2001). Prior to the hearing, the Commission’s staff had been concerned about the inaccuracy of timelines offered by the military. Author Philip Shenon will write: “It seemed all the more remarkable to [Commission staffer John Farmer] that the Pentagon could not establish a clear chronology of how it responded to an attack on the Pentagon building itself. Wouldn’t the generals and admirals want to know why their own offices—their own lives—had been put at risk that morning?” Therefore, Farmer thought that the hearing should clear things up, but, according to Shenon, he and his colleagues are “astonished” when they analyze what Arnold says, although he is not under oath on this day. Shenon will add, “It would later be determined that almost every one of those assertions by General Arnold in May 2003 was flat wrong.” [Shenon, 2008, pp. 119-121]

Shyam Sunder.Shyam Sunder. [Source: NIST]The National Institute of Standards and Technology (NIST) releases nearly 500 pages of documents, detailing the latest findings of its investigation of the WTC collapses on 9/11. These include its hypotheses for the collapse sequences of each of the Twin Towers; details of their analysis of interviews with nearly 1,200 building occupants, emergency responders, and victims’ relatives; and information from their analysis of the emergency response and evacuation procedures. Their investigation into the collapses is based upon an analysis of thousands of photos and videos, examination of many of the elements used to construct the towers, and computer-enhanced modeling of the plane impacts and the spreading of the fires. Their hypothesis is that the towers collapsed ultimately due to the fires they suffered: As the fires burned, the buildings’ steel core columns buckled and shortened. This shifted more load to the buildings’ perimeter columns, which were already affected by the heat of the fires, and caused them to give way under the increased stress. Investigators have conducted a test with a reconstructed section of the WTC floor, and found that the original fireproofing was sufficient to meet the New York City building code. They say that had a typical office fire occurred in the towers, without the structural damage and the loss of some fireproofing caused by the plane impacts, it is likely the buildings would have remained standing. Lead investigator Dr. Shyam Sunder says, “The buildings performed as they should have in the airplane impact and extreme fires to which they were subjected. There is nothing there that stands out as abnormal.” NIST’s theories of why the WTC buildings collapsed conflict with an earlier investigation by FEMA, which claimed the collapse of the North Tower had begun in its core, rather than its perimeter columns (see May 1, 2002).

The National Institute of Standards and Technology (NIST), which is conducting an investigation into the WTC collapses on 9/11, releases three new reports. Investigators say that the Twin Towers would probably have remained standing if the fireproofing material that surrounded the buildings’ structural steel had not been stripped away when the planes hit. Their report states that “[t]he jet fuel, which ignited the fires, was mostly consumed within the first few minutes after impact. The fires that burned for almost the entire time that the buildings remained standing were due mainly to burning building contents and, to a lesser extent, aircraft contents, not jet fuel.” However, they claim, without the loss of fireproofing during the planes’ impacts, the heat from the fires would have been insufficient to cause the buildings to collapse. They say that although the architects had in 1964 tested the impact of a Boeing 707 airplane crashing into the 80th floor of one of the towers, they never envisioned the intense fires that ensued. NIST also reports that the time taken by survivors from the North Tower to descend a flight of stairs was about double the slowest evacuation speed estimated in a standard fire engineering text. They state: “approximately 87 percent of the WTC tower occupants, including more than 99 percent below the floors of impact, were able to evacuate successfully.” However, they say, if each tower had been full when they were hit, as many as 14,000 people could have died.

A report is secretly delivered to Congress by the Pentagon’s Office of Inspector General, regarding the inaccuracy of statements made by Defense Department officials on the military’s response to the September 11 hijackings. The 9/11 Commission made a formal request in summer 2004 for the inspector general to investigate the matter, because military officials had given testimony that was later proved to have been false (see Shortly before July 22, 2004). For example, they claimed that NORAD had been tracking Flight 93 on 9/11 and was ready to shoot it down if it threatened Washington (see Shortly Before 9:36 a.m. September 11, 2001 and (9:36 a.m.-10:06 a.m.) September 11, 2001). Yet audiotapes obtained under subpoena showed NORAD was unaware of this flight until after it crashed. In its report, the inspector general’s office states that it found “the inaccuracies, in part, resulted because of inadequate forensic capabilities.” It says that commanders found it difficult to create an accurate timeline of the events of 9/11 due to the lack of a well-coordinated system in logging information about air defense operations. At the time, air defense watch centers had used handwritten logs, and these could be unreliable. Following the attacks, the report claims, commanders failed to press hard enough for an accurate timeline to be produced for the benefit of investigations, like the 9/11 Commission. Yet, as some of the Commission’s staff will later point out, the military had already reviewed the NORAD audiotapes chronicling the events of 9/11 prior to its officials giving their incorrect testimonies. In response to a freedom of information request by the New York Times, the inspector general’s report will be publicly released in August 2006, but the equivalent of several pages will be blacked out on national security grounds. [Vanity Fair, 8/1/2006; Washington Post, 8/2/2006; New York Times, 8/5/2006; Reuters, 8/5/2006; US Department of Defense, 9/12/2006 pdf file]
9/11 Staff Member Criticizes Report - In his 2009 book The Ground Truth, John Farmer, who served as senior counsel to the 9/11 Commission, will criticize the inspector general’s report. Farmer says the report mischaracterizes the 9/11 Commission’s referral by saying the Commission had alleged officials knowingly made false statements, when instead it had simply “documented the facts concerning what occurred on 9/11, the disparity between those facts and what the government had been telling the public with total assurance since 9/11, and the relative ease with which anyone looking could have uncovered those facts.” He faults the inspector general for interpreting the issue narrowly, by focusing on statements made to the 9/11 Commission; ignoring the larger context in which the events of 9/11 were extremely significant and so it should have been extremely important for the military to understand the truth of what happened, in order to correct any problems, as well as to be able to present an accurate account to the White House and to the public; and failing to address the question of whether the false accounts had served anyone’s interests. The inspector general’s report affirms the claims of top NORAD commanders that, in Farmer’s words, they had been “simply too busy fixing the system and fighting the war on terror to concern themselves with piecing together the facts of 9/11.” Farmer will ask, “[H]ow… could the Department of Defense identify and correct operational weaknesses without knowing precisely what had occurred that morning?” He will question the report’s determination that the Defense Department lacked the forensic capabilities for maintaining logs, video and audio recordings, and storing radar information, and had not coordinated with the FAA on reconstructing the events of 9/11, as the Commission had documented evidence that the two agencies had indeed coordinated while developing their reconstructions of events. Farmer will write that “it is impossible to conclude honestly, from the two inspector general reports, that the official version of the events of 9/11 was the result of mere administrative incompetence; too many questions remain unanswered.” He will add, “History should record that whether through unprecedented administrative incompetence or orchestrated mendacity, the American people were misled about the nation’s response to the 9/11 attacks.” [Farmer, 2009, pp. 283-289]

National Institute of Standards and Technology (NIST) releases a 12-page appendix to its final reports on the WTC collapses (see October 26, 2005) detailing tests it conducted on samples of the type of fireproofing used in the WTC. An earlier NIST report had concluded that loss of fireproofing was a major factor in the collapses (see April 5, 2005). The appendix was not included in earlier drafts of the report (see June 23, 2005) [National Institute of Standards and Technology, 6/23/2005 pdf file; National Institute of Standards & Technology, 9/2005, pp. 263-274 pdf file; National Institute of Standards and Technology, 9/2005, pp. 149] NIST conducted a series of fifteen tests. In the tests projectiles were fired at fireproofing mounted on 12 inch x 12 inch plates, and steel bars with a one inch diameter. The fireproofing used in the tests was Blazeshield DC/F, one of the two grades of fireproofing used on the impact floors. In thirteen of the tests the projectiles were buckshot, which was fired at the steel samples from a modified shotgun at a distance of 29.5 ft. The other two tests used steel bolts and hexagon nuts, fired with less velocity and at closer range. According to NIST, “The test results support the assumption that, within the debris field created by the aircraft impact into WTC 1 and WTC 2, the SFRM [i.e., fireproofing] used for thermal insulation of structural members was damaged and dislodged.” [National Institute of Standards & Technology, 9/2005, pp. 83, 263-274 pdf file]
