Acting Chairman of the Joint Chiefs of Staff Richard Myers enters the National Military Command Center (NMCC) within the Pentagon, though exactly when this happens remains unclear. According to his own statements, he was on Capitol Hill, in the offices of Senator Max Cleland (D-GA), from just before 9:00 a.m. until around the time the Pentagon was hit. He’d then headed back to the Pentagon (see Shortly Before 9:00 a.m. September 11, 2001 and (Shortly After 9:37 a.m.) September 11, 2001). (Armed Forces Radio And Television Service 10/17/2001; Myers 9/11/2002; Myers 6/29/2006) According to the 9/11 Commission, Myers joins the air threat conference call from the NMCC at “shortly before 10:00.” (9/11 Commission 7/24/2004, pp. 38) But the American Forces Press Service reports that he arrives at the NMCC “about 15 minutes” before Secretary of Defense Donald Rumsfeld (who arrives around 10:30), meaning at about 10:15 a.m. (Garamone 9/8/2006) Rumsfeld claims that, as he enters the NMCC, Myers has “just returned from Capitol Hill.” (9/11 Commission 3/23/2004) Cleland verifies that Myers was with him on Capitol Hill until around the time of the Pentagon attack. (CNN 11/20/2001; Baxter and Galloway 6/16/2003) But counterterrorism “tsar” Richard Clarke claims that Myers has been taking part in a video conference since shortly after the second attack on the WTC, and has been visible on the Pentagon screen (see (9:10 a.m.) September 11, 2001 and 9:28 a.m. September 11, 2001), thereby implying Myers has been at the Pentagon all along. (Clarke 2004, pp. 3 and 5) Myers tells the 9/11 Commission, “After I reached the National Military Command Center (NMCC), I asked questions to determine where Secretary Rumsfeld was, how the FAA was handling airborne flights, and the status of fighters prepared to intercept any hijacked aircraft inbound to Washington.” (9/11 Commission 6/17/2004 pdf file)

FAA radar displays begin showing that a growing number of international flights approaching America are transmitting warning codes from their transponders. (Spencer 2008, pp. 196-197)
Airspace Shut Down - At around 9:45 a.m., the FAA shut down US airspace and ordered all aircraft to land (see (9:45 a.m.) September 11, 2001). Shortly afterwards, Canada took similar action. However, international flights that are over the oceans and approaching America are getting low on fuel. As their crews establish radio contact with air traffic controllers, they are told that American airspace is closed. Many of the worried pilots dial emergency codes into their transponders. (US Congress. House. Committee On Transportation And Infrastructure 9/21/2001; 9/11 Commission 7/24/2004, pp. 29; Spencer 2008, pp. 196)
Radar Screens Highlight Numerous Flights - A plane’s transponder is a device that sends that aircraft’s identifying information, speed, and altitude to radar screens. (Maraniss 9/16/2001) There are three specific codes that pilots can dial into their transponder to signal an emergency: “7500” signifies a hijacking, “7600” signifies a loss of radio, and “7700” signifies other emergencies. (Spencer 2008, pp. 25-26) Amid the current crisis, FAA radar screens begin highlighting a growing number of flights over the oceans that are transmitting warning codes. According to author Lynn Spencer, “One foreign crew dials in the four-digit code for ‘hijack,’ just to let the authorities know they are aware of what is taking place.” (Spencer 2008, pp. 196-197) In response to a request from the FAA, Canada will agree to open its airspace to all international flights that are diverted away from the United States, allowing those flights to land at Canadian airports (see 10:21 a.m. September 11, 2001). (CNN 9/12/2001; Donnelly 9/14/2001; NAV Canada 7/22/2005)

Lynne Cheney, the wife of Vice President Dick Cheney, joins her husband in an underground tunnel that leads to the Presidential Emergency Operations Center (PEOC) below the White House. (Cheney 11/9/2001; 9/11 Commission 7/24/2004, pp. 40) Cheney has been driven to the White House by her Secret Service agents after they evacuated her from a hair salon in Washington, DC (see (Shortly After 9:33 a.m.) September 11, 2001). (United States Secret Service 10/1/2001) As they were making their way through the White House, Cheney and the Secret Service agent accompanying her ran into I. Lewis “Scooter” Libby, the vice president’s chief of staff, and Libby then joined them as they headed toward the PEOC (see 9:52 a.m. September 11, 2001). In the underground tunnel that leads to the PEOC, Cheney, the Secret Service agent, and Libby find the vice president. (Libby 11/14/2001) Vice President Cheney was being taken to the PEOC by his Secret Service agents (see (9:36 a.m.) September 11, 2001), but stopped in an area of the underground tunnel where there is a secure telephone, in order to speak to President Bush (see (9:37 a.m.) September 11, 2001 and (9:45 a.m.-9:56 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 39-40) He is on the phone with Bush when his wife reaches him. (Cheney 9/11/2001; Cheney 11/9/2001) Dick and Lynne Cheney will enter the PEOC at around 9:58 a.m., according to the 9/11 Commission Report (see (9:58 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 40)

The air traffic control tower at Washington’s Reagan National Airport is evacuated, after it is informed that a suspicious aircraft—presumably Flight 93—is heading its way.
Warning of Approaching Aircraft - In the control tower, supervisor Chris Stephenson receives a call from the FAA’s Herndon Command Center, telling him: “You have another [aircraft] headed your way. Confirmed bomb on board.” This information also makes it to the Terminal Radar Approach Control (TRACON) at the airport. Around this time, the Command Center changes the information it has for Flight 93’s flight plan, so that it shows a destination of Reagan Airport (see 9:55 a.m. September 11, 2001). This means air traffic controllers are now able to track the flight on their situation displays. But in response to the news that the approaching aircraft has a bomb on board, the facility manager at Reagan Airport becomes concerned about the safety of his employees and decides to evacuate the control tower.
Tower Controllers Evacuated - Dan Creedon, a controller in the TRACON, tries calling the tower repeatedly, to pass on the manager’s instruction to evacuate, but he is unable to get through. He therefore leaves his post and takes the elevator up the tower. Once he reaches the control tower cab, he announces that there are to be “minimum bodies” in the tower, with only a skeletal staff remaining. Four controllers therefore volunteer to leave. (Spencer 2008, pp. 215-216) (Seven or eight controllers usually work in the tower during a given shift, so this would mean three or four controllers remain there. (9/11 Commission 7/28/2003 pdf file) )
Terminal Being Evacuated - When they make it down to the airport terminal, the controllers find that it too is being evacuated. Police are yelling at the crowd: “Everybody’s got to go! There are no more flights! Leave your stuff! Just go! It doesn’t matter where you go, just get away from the airport.”
Other Controllers Head to Mobile Unit - The controllers who had remained behind decide they too should leave the tower and relocate to an emergency mobile unit. Before doing so, they temporarily turn over the command and control of their airspace to Washington, DC, police helicopters. They are then escorted by members of the Secret Service down from the tower and through the terminal. (Spencer 2008, pp. 216)

At NORAD’s Northeast Air Defense Sector (NEADS), two weapons controllers are instructed to come up with a battle plan for defending the US, and in response quickly piece together an extensive strategy. Major James Fox, the leader of the weapons team, comes over to the weapons station on the NEADS operations floor. He points at weapons controllers Trey Murphy and Michael Julian, both of whom are graduates of the Air Force’s Fighter Weapons School, and says, “The boss wants you two.” Murphy and Julian head upstairs to the glass-enclosed battle cab, where battle commander Colonel Robert Marr is waiting for them. Murphy asks, “What do you need me to do?” Marr responds, “Un-f_ck this!” Murphy takes this to mean: “Right now, I have chaos. Bring me order. Make me a battle plan.” Murphy and Julian head back to the operations floor to get their notebooks and pens, and then look for somewhere quiet to work. They find an empty conference room, and immediately begin working on a defense strategy for the United States. The two men come up with everything that needs to be in place to defend the major cities: the fighter jets required, the altitudes the jets should fly at, the requirements for tanker planes, and the radio frequencies that will be needed. Within minutes, they have pieced together an extensive plan. Murphy and Julian then return to the battle cab, where they set about putting it into action. (Spencer 2008, pp. 188-190)

Two F-16s from the 147th Fighter Wing, Ellington Air National Guard Base, Texas, are said to be already airborne on a local training mission when they are instructed to escort Air Force One after it departs Sarasota, Florida, with President Bush on board. (Arnold 12/2001 pdf file; Code One Magazine 1/2002)

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; Carroll 9/2006 pdf file; Casey 9/6/2006; Spencer 2008, pp. 178) However, some accounts will claim the pilots are indeed ordered to intercept the suspect aircraft. (Raddatz 8/30/2002; Associated Press 8/30/2002; Baker 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; Carroll 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. (Casey 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.” (Carroll 9/2006 pdf file; Casey 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; Baker 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; Carroll 9/2006 pdf file; Casey 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.” (Carroll 9/2006 pdf file; Casey 9/6/2006)

A US Park Police helicopter flying above the burning Pentagon.A US Park Police helicopter flying above the burning Pentagon. [Source: Mark D. Faram / US Navy]A US Park Police helicopter that recently arrived over the Pentagon is contacted by an air traffic controller at Washington’s Reagan National Airport and given responsibility for controlling the airspace over Washington, DC, since the control tower at Reagan Airport is being evacuated. (Galey 11/20/2001; US Department of Health and Human Services 7/2002, pp. A-48 pdf file; McDonnell 2004, pp. 21 pdf file) The Park Police Aviation Unit’s two helicopters arrived at the Pentagon within minutes of the attack there (see Shortly After 9:37 a.m. September 11, 2001). (Forror 11/2001) While one of the helicopters landed to conduct medical evacuations, the other, which has the call sign “Eagle I,” circled overhead. (Galey 11/20/2001; McDonnell 2004, pp. 20-21 pdf file)
Airport Tower Being Evacuated - Eagle I has made three or four orbits around the Pentagon when a controller in the Reagan Airport tower radios its pilot, Sergeant Ronald Galey. The controller says the tower is currently evacuating. (Galey 11/20/2001; Galey 1/17/2002) According to some accounts, the tower is being evacuated due to reports of more hijacked aircraft heading in its direction (see (9:55 a.m.) September 11, 2001). (NBC 4 9/11/2003; Spencer 2008, pp. 215-216) But according to other accounts, the controller tells Galey the tower is evacuating because it is being affected by smoke that is drifting across from the burning Pentagon. (US Department of Health and Human Services 7/2002, pp. A-48 pdf file; McDonnell 2004, pp. 21 pdf file; Goldberg et al. 2007, pp. 162) Galey will recall the controller saying: “Eagle I, we can’t see anything outside the tower. [The smoke is] getting in our ventilation system. We’re abandoning the tower.” Therefore, the controller gives Galey control of the airspace for the entire Washington area, telling him, “You’ve got the airspace.” (Galey 11/20/2001; McDonnell 2004, pp. 21 pdf file)
Pilot Alarmed at Being Given Control of Airspace - The control tower at Reagan Airport is “normally the ‘nerve center’ for directing any response to this type of incident,” according to a National Park Service news article. (Line 9/21/2002) Galey is initially alarmed. He will recall thinking, “Exactly what I need right now is I’ve got control of the airspace.” (Galey 11/20/2001) However, he is unaware that the FAA has ordered that all airborne aircraft must land at the nearest airport (see (9:45 a.m.) September 11, 2001), which will make his task easier. (US Congress. House. Committee On Transportation And Infrastructure 9/21/2001; McDonnell 2004, pp. 21 pdf file; 9/11 Commission 7/24/2004, pp. 29)
NORAD Advises Pilot on Controlling Airspace - The controller gives Galey the radio frequency for NORAD, and tells him to contact NORAD. (Galey 1/17/2002; McDonnell 2004, pp. 21-22 pdf file) The person Galey then talks to at NORAD informs him: “Look, you have no [air] traffic in DC, except for the traffic that you’re calling. The aircraft that you’re calling in, we’re going to allow to come in. Other than that, there should be no one besides the military, and we’ll call you out the military traffic.” Galey will later reflect: “So that helped tremendously. That function alone was not very taxing.” (Galey 11/20/2001) The person at NORAD also tells Galey there is “an unauthorized aircraft inbound from the Pennsylvania area, with the estimated time of arrival approximately 20 minutes into DC.” Galey will recall that he and the rest of his crew discuss what they should do, and decide that “we’d take our chances and stay there [at the Pentagon], and do what we came there to do.” (Galey 1/17/2002)
Airspace Control Passed on to Metropolitan Police Helicopter - Eagle I becomes “the air traffic control function for the area, flying a slow racetrack pattern over the site and clearing aircraft in and out,” according to Lieutenant Philip Cholak, the Park Police Aviation Unit commander. (Wagstaff 10/1/2001) But after a time Galey asks his paramedic to request that a Metropolitan Police helicopter be launched to take over the command and control of the Washington airspace. He tells the paramedic: “You know we’re going to have to do a medevac mission here. We’re going to have to relinquish the command/control function to somebody else.” A Metropolitan Police helicopter subsequently arrives and relieves Eagle I of its command and control function. (Galey 11/20/2001; McDonnell 2004, pp. 22 pdf file)

An air traffic controller at the FAA’s Cleveland Center enters a new flight plan for Flight 93 into the FAA computer system, giving a new destination of Reagan National Airport in Washington, DC. Flight 93 is currently flying in the airspace covered by the Cleveland Center’s Imperial Sector radar position, which is being managed by controller Linda Justice. (Federal Aviation Administration 9/11/2001; Ballingrud 9/12/2001; 9/11 Commission 10/2/2003 pdf file; Lynn Spencer 2008)
Controller Enters New Flight Plan for Flight 93 - Justice changes the flight’s destination code from “SFO,” the code for San Francisco International Airport, to “DCA,” the code for Ronald Reagan Washington National Airport. (Ballingrud 9/12/2001) An FAA chronology will specify that she changes the flight plan “direct HGR [the code for Hagerstown Regional Airport in Maryland] to DCA.” (Federal Aviation Administration 9/11/2001) Another FAA chronology will similarly state that Justice reroutes Flight 93 “direct to Hagerstown direct to Washington National.” (Federal Aviation Administration 12/6/2001) Flight 93’s tag therefore now reads, “Hagerstown—National,” according to Justice. (9/11 Commission 10/2/2003 pdf file)
New Flight Plan Not Due to Communication with Pilot - The reason Justice enters a new flight plan for Flight 93 is unclear. A minute earlier, the hijacker pilot on Flight 93 reprogrammed the plane’s navigational system for the new destination of Reagan Airport (see 9:55 a.m. September 11, 2001). (Longman 2002, pp. 182; 9/11 Commission 7/24/2004, pp. 457) And according to the St. Petersburg Times, controllers typically only change a plane’s destination when this is requested by the pilots. (Ballingrud 9/12/2001) But one of the FAA chronologies will state that Justice’s change to the flight plan is “not a result of any communication with the pilot.” (Federal Aviation Administration 9/11/2001)
Flight Plan Changed to Aid Handoff to Washington Controllers - Justice will later explain why she changes the flight plan. She will state that Flight 93 appears to be heading toward the airspace of the FAA’s Washington Center, and so, in “an attempt to expedite the situation,” she enters the change of routing to reflect Hagerstown Airport to Reagan Airport. She will say she does this “only to forward [the] information [about Flight 93] to the sectors the aircraft appeared to be tracking toward.” (Federal Aviation Administration 9/12/2001 pdf file) Justice will tell the 9/11 Commission that she changes the routing when she sees Flight 93 is heading eastbound. She will say, “The easiest way to do a handoff is to change the flight plan,” and also say she changes the flight plan “to show that Washington Center was the recipient.” According to Justice, the “controversial step” she takes is “putting in Hagerstown, because the misconception was that she had communicated with the plane and cleared it through.” (9/11 Commission 10/2/2003 pdf file) John Werth, another controller at the Cleveland Center, will tell the 9/11 Commission that Justice enters the new destination for Flight 93 “because she knew it would be easier to track the primary [radar track for the aircraft] when the computer has a flight plan to work with.” (9/11 Commission 10/1/2003 pdf file) After changing the flight plan, Justice calls the Potomac Sector radar position at the Washington Center and tells the controller there to “pull up the data block” for Flight 93. Justice will say it is clear to the Washington Center controller that she has created the new destination in order to make it easier to locate the plane. (Federal Aviation Administration 9/12/2001 pdf file; 9/11 Commission 10/2/2003 pdf file)
New Flight Plan Causes False Reports of Plane Approaching Washington - According to author Lynn Spencer, the new flight plan creates a “coast track” of Flight 93 on the traffic situation displays at air traffic control facilities. “A coast track,” Spencer will write, “differs from a radar track in that it is not supported by radar returns but rather by a computer-generated, projected course for the flight. Although this track did not appear on controller radar screens, its presence on their [traffic situation displays] allowed Washington controllers to monitor the flight’s progression toward Washington.” According to Spencer, the presence of this coast track leads to incorrect reports of an aircraft approaching Washington in the minutes after Flight 93 crashes. She will write, “A controller in Washington, unaware that the flight had crashed, was calling position reports for the coast track of United 93 to the White House (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001)… as well as the FBI at the Pentagon (where firefighters were evacuated and the firefight suspended in anticipation of a second impact)” (see (10:15 a.m.-10:38 a.m.) September 11, 2001). (Lynn Spencer 2008)

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

Air Force One takes off and quickly gains altitude. One passenger later says, “It was like a rocket. For a good ten minutes, the plane was going almost straight up.” (CBS 9/11/2002) Once the plane reaches cruising altitude, it flies in circles. Journalists on board sense this because the television reception for a local station generally remains good. “Apparently Bush, Cheney, and the Secret Service argue over the safety of Bush coming back to Washington.” (Tapper 9/12/2001; Langley 12/16/2001) For much of the day Bush is plagued by connectivity problems in trying to call Cheney and others. He is forced to use an ordinary cell phone instead of his secure phone. (9/11 Commission 6/17/2004)

Douglas Cochrane, Vice President Dick Cheney’s military aide, joins Cheney in an underground tunnel that leads to the Presidential Emergency Operations Center (PEOC) below the White House and is told that an aircraft hit the Pentagon. After Flight 175 crashed into the World Trade Center at 9:03 a.m., Cochrane went from the White House to his office in the Eisenhower Executive Office Building, next to the White House, to fetch a special briefcase that holds the codes necessary to initiate a nuclear attack (see 9:03 a.m. September 11, 2001). When he arrived back at the White House, he saw Cheney being evacuated from his office by his Secret Service agents (see (9:36 a.m.) September 11, 2001). Cochrane tried to follow Cheney as he was being escorted to the underground tunnel that leads to the PEOC, but the door to the tunnel was shut behind the vice president. Cochrane said, “Open the door,” but agents there said they could not do this. He therefore had to take another route to get to the tunnel. Cochrane now joins Cheney. He finds that Lynne Cheney, the vice president’s wife, has joined Cheney in the tunnel (see (9:55 a.m.) September 11, 2001) and the group around the vice president is getting ready to head to the PEOC. While Cochrane is in the tunnel, a Secret Service agent tells him, “They just got the Pentagon.” Cochrane will later comment that before receiving this notification, he had been unaware that an aircraft was approaching Washington, DC. He will go with Cheney and the group accompanying the vice president into the PEOC (see (9:58 a.m.) September 11, 2001), and stay in the PEOC for the rest of the day. (9/11 Commission 4/16/2004)

Since 9:45 a.m., Flight 93 passenger Todd Beamer has been talking by Airfone to Lisa Jefferson, a GTE customer service supervisor (see 9:45 a.m.-9:58 a.m. September 11, 2001). Beamer is a devout Christian, and asks Jefferson to recite the Lord’s Prayer with him. He then recites the 23rd Psalm. He also gives her his home phone number and tells her to contact his wife if he does not survive, and let his family know how much he loves them. (van Derbeken 9/17/2001; McKinnon 9/22/2001; Longman 2002, pp. 198-200) He tells Jefferson that some of the passengers are going to “jump” the hijacker who claims to have a bomb, and try to seize control of the plane. He says, “We’re going to do something. I know I’m not going to get out of this.” In the background, Jefferson can hear an “awful commotion” of people shouting, and women screaming, “Oh my God,” “God help us,” and “Help us Jesus.” Beamer lets go of the phone but leaves it connected. Jefferson can hear him speaking to someone else, saying the words that later become famous: “Are you ready guys? Let’s roll” (alternate version: “You ready? Okay. Let’s roll”). (Breslau 9/22/2001; Pittsburgh Post-Gazette 10/28/2001; Longman 2002, pp. 203-204) Beamer reportedly talks to Jefferson for 13 minutes, meaning his last words to her are at 9:58 a.m. (McKinnon 9/16/2001; McKinnon 9/19/2001) Jefferson then hears more screaming and other commotion. She remains on the phone until after the time Flight 93 crashes (see (9:59 a.m.-10:49 a.m.) September 11, 2001). (Smith 9/5/2002)

President Bush talks on the phone to Vice President Dick Cheney. Cheney recommends that Bush authorize the military to shoot down any plane that might be under the control of hijackers. “I said, ‘You bet,’” Bush later recalls. “We had a little discussion, but not much.” (Weisman 9/16/2001; Adcock, Donovan, and Gordon 9/23/2001; Balz and Woodward 1/27/2002; Kohn 9/2/2003) Bush recalls that this isn’t a difficult decision for him to make, “once I realized there was a protocol… because again, I now realized we’re under attack. This is a war.” According to journalists Bob Woodward and Bill Sammon, this call between Bush and Cheney takes place shortly after 9:56, when Air Force One took off from the Sarasota airport. (Sammon 2002, pp. 102; Woodward 2002, pp. 17-18; Balz and Woodward 1/27/2002) Consistent with this, Bush and Cheney will tell the 9/11 Commission that Bush gives the shootdown authorization during a call estimated to occur between about 10:00 and 10:15 (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). But the 9/11 Commission will say the authorization is given in a later call, at 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 40-41) Bush later indicates that he doesn’t make any major decisions about how to respond to the attacks until after boarding Air Force One, which fits with these accounts of him approving shootdown authorization after take off. (Bush 12/4/2001; Paltrow 3/22/2004 pdf file) But according to counterterrorism “tsar” Richard Clarke, the authorization is given earlier, at some point between about 9:38 and 9:56 (see (9:38 a.m.) September 11, 2001 and (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). (Koppel 11/29/2003; Clarke 2004, pp. 8)

One of the hijackers in the cockpit asks if anything is going on, apparently meaning outside the cockpit. “Fighting,” the other says. (Longman 2002, pp. 210) An analysis of the cockpit flight recording suggests that the passenger struggle actually starts in the front of the plane (where Mark Bingham and Tom Burnett are sitting) about a minute before a struggle in the back of the plane (where Todd Beamer is sitting). (Vulliamy 12/2/2001) Officials later theorize that the Flight 93 passengers reach the cockpit using a food cart as a battering ram and a shield. They claim digital enhancement of the cockpit voice recorder reveals the sound of plates and glassware crashing around 9:57 a.m. (Breslau, Clift, and Thomas 12/3/2001)

The sound of fighting can be heard from the cockpit of Flight 93 as passengers apparently begin a sustained attempt to retake control of the plane. Passengers on Flight 93 begin their revolt at 9:57 a.m., according to the 9/11 Commission Report (see 9:57 a.m. September 11, 2001). (Vulliamy 12/2/2001; 9/11 Commission 7/24/2004, pp. 13)
Hijacker Wonders if a Fight Is Taking Place - The cockpit voice recording from the plane will later reveal that hijackers in the cockpit, apparently aware of what is happening, start discussing the noise coming from outside the cockpit door around this time. Speaking in Arabic, one of them asks: “Is there something? A fight?” Another hijacker responds, “Yeah.” The sound of a light knock on the cockpit door is then picked up by the cockpit voice recorder, followed by the sound of the door opening. The sound of a male screaming in the distance is picked up, along with the sound of fighting in the background. One of the hijackers then apparently starts praying, saying: “Allah is greatest. Allah is greatest. Oh guys! Allah is greatest.” He then exclaims: “Oh Allah! Oh Allah! Oh, the most gracious!”
Hijacker Says to Hold the Cockpit Door Closed - As the sound of fighting continues, a person identified in an FBI transcript of the cockpit voice recording as a “native English-speaking male”—presumably one of the passengers—says: “In the cockpit! In the cockpit!” One of the hijackers, still speaking in Arabic, apparently comments on the passengers’ attempt to break into the cockpit. “They want to get in there,” he says. He then issues the instruction: “Hold [the door], hold from the inside. Hold from the inside. Hold.”
Passengers Struggle against the Hijackers - A male passenger then exclaims, “Stop him!” Apparently referring to the passengers, one of the hijackers says: “There are some guys. All those guys.” A male passenger says, “Let’s get them!” With the sound of fighting continuing in the background, one of the hijackers says, “Trust in Allah and in him.” In the space of 15 seconds, the cockpit voice recorder then picks up the sound of “a loud metal-to-metal snap,” the sound of a “loud thump,” a “series of very loud crashes,” and the sound of glasses and plates breaking. A hijacker shouts, “Ah!” and then the crashing sounds end. (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 102-103)
Investigators Will Determine that a 'Great Struggle' Occurs - The 9/11 Commission will suggest that the sounds picked up by Flight 93’s cockpit voice recorder at this time indicate that “a great struggle began at the back of the airplane and progressed toward the front.” (9/11 Commission 8/26/2004, pp. 45) David Novak, the lead prosecutor in the case of al-Qaeda conspirator Zacarias Moussaoui, will theorize what happened, based on the cockpit voice recording, saying that the passengers have advanced into the cockpit, using a food cart as a shield. Officials will suggest that the crashing sounds that are picked up by the cockpit voice recorder “could have come as passengers hurled plates and glasses, or as the dishes fell from a meal cart when the plane’s wings began rocking,” according to journalist and author Jere Longman. (Longman 2002, pp. 270-271)

Deena Burnett has just minutes earlier spoken by phone with her husband, Tom Burnett, a passenger on Flight 93 (see 9:54 a.m. September 11, 2001). According to Deena Burnett’s account that she presents in her own book in 2006, an FBI agent she talked with after her husband’s first call (see 9:31 a.m.-9:34 a.m. September 11, 2001) now calls and speaks to her again, briefly. She tells the agent she has just got off the phone with her husband. He wants to know if Tom provided any details of the hijackers, such as how many there are and what language they speak, but Deena says no. She says the only background noise she heard was other people who seemed to be sitting near her husband, speaking English. During Tom’s final call, the background was silent. The agent says the FBI has tried calling Tom’s cell phone, but there was no answer. (Burnett and Giombetti 2006, pp. 68-69) According to the account in Deena Burnett’s book, this appears to be her first contact with the FBI since she made her 911 call at 9:31. But according to journalist and author Jere Longman, Deena called the FBI shortly after 9:35, following her second call from her husband (see (Between 9:36 a.m. and 9:45 a.m.) September 11, 2001). (Longman 2002, pp. 110) Deena will speak with the FBI again more than two hours later, when three agents arrive at her house to interview her (see (12:30 p.m.) September 11, 2001).

[Source: Gonda Moncada / Texas Military Forces]Four armed F-16 fighter jets belonging to the Texas Air National Guard are directed toward Air Force One in order to escort the president’s plane.

SEADS Sends Fighters toward Air Force One - Air Force One has taken off from Sarasota, Florida (see 9:54 a.m. September 11, 2001), and the White House has requested a fighter escort for it (see 9:59 a.m. September 11, 2001). (Martin 7/4/2004; 9/11 Commission 7/24/2004, pp. 38) NORAD’s Southeast Air Defense Sector (SEADS) orders jets that belong to the 147th Fighter Wing of the Texas Air National Guard toward the president’s plane. (Hehs 4/2002; Filson 2003, pp. 87; Rosenfeld and Gross 2007, pp. 40) Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will later recall: “We were not told where Air Force One was going. We were told just to follow the president.” (Code One Magazine 1/2002)
Ellington Field an 'Alert' Site - The 147th Fighter Wing is based at Ellington Field, a joint civil and military use airport about 15 miles south of Houston. (Rendon 12/9/2003; GlobalSecurity (.org) 8/21/2005; GlobalSecurity (.org) 1/21/2006) Ellington Field is one of NORAD’s seven “alert” sites around the US, which all have a pair of armed fighters ready to take off immediately if called upon. (McKenna 12/1999; Hebert 2/2002)
Pilots Not Told What Their Target Is - Two of the F-16s sent toward Air Force One are on the ground at Ellington Field and have been placed on “battle stations,” with the pilots sitting in the cockpits, when the scramble order is received. (Hehs 4/2002) The other two have been flying a training mission (see After 9:55 a.m. September 11, 2001), and are pulled off it to escort Air Force One. (Arnold 12/2001 pdf file; Spencer 2008, pp. 255) Among the four pilots are Shane Brotherton and Randy Roberts. Their new mission is so secret that their commander does not tell them where they are going. When they ask what their target is, the commander says, “You’ll know when you see it.” Brotherton will later recall, “I didn’t have any idea what we were going up [for] until that point.” (Kohn 9/11/2002; Spencer 2008, pp. 255)
Jets First to Reach Air Force One - At least two of the 147th Fighter Wing F-16s will be seen from Air Force One at around 11:30 a.m., although an official will tell reporters on board that fighters are escorting the plane about 15 minutes before that time (see (11:29 a.m.) September 11, 2001). They are the first fighters to reach Air Force One after it left Sarasota, according to most accounts. (Keen and Carney 9/11/2001; Kohn 9/11/2002; Filson 2003, pp. 87; Martin 7/4/2004; Rosenfeld and Gross 2007, pp. 40; Spencer 2008, pp. 255) However, a few accounts will indicate the first jets to reach it belong to a unit of the Florida Air National Guard located at Jacksonville International Airport (see (10:00 a.m.) September 11, 2001). (US Department of Defense 9/2001; Langley 12/16/2001) The 147th Fighter Wing F-16s will accompany Air Force One all the way to Washington, DC. (Filson 2003, pp. 87-88; Cousins 7/9/2005)

McChord Air Force Base.McChord Air Force Base. [Source: Michel Teiten]Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), calls NORAD’s Western Air Defense Sector (WADS), which is at McChord Air Force Base in Washington State, to request assistance. He says: “I’d like to… steal some aircraft out of Fargo from you guys.… Bring up the weapons too, if possible,” to which WADS replies: “Yep, ok. We will do that.” (North American Aerospace Defense Command 9/11/2001) The three F-16s launched from Langley Air Force Base at 9:30 (see (9:25 a.m.-9:30 a.m.) September 11, 2001) are in fact from the North Dakota Air National Guard’s 119th Fighter Wing, which, though based at Fargo, ND, has had a detachment of two F-16s on alert at Langley since late 2000. However, these are under the command of NEADS, not WADS. (Sizemore 9/22/2001; Wald and Sack 10/16/2001; McChord Air Museum 2007) It is therefore not clear what specific fighters are now being referred to when Nasypany speaks of the “aircraft out of Fargo,” nor is it clear if and when these planes are launched. Colonel John Cromwell, the commander of WADS, will later recall that he calls every fighter wing commander west of the Mississippi, and by midday (3:00 p.m. ET) has more than 100 fighter jets on alert.

[Source: Shannon Stapleton]Almost all the occupants of the South Tower who are able to evacuate the building have done so and have crossed the street to safety. Only 11 occupants who were below the impact floors are still in the building when it collapses. However, 619 building occupants in or above the impact zone have either already died or perish in the collapse, as do many emergency workers. (National Institute of Standards and Technology 9/2005, pp. xxxix, 44) Most workers in the North Tower also leave the building before it collapses (see 10:27 a.m. September 11, 2001).

Edward Felt.
Edward Felt. [Source: Family photo]An emergency call is received at the 911 center in Westmoreland County, Pennsylvania, from Edward Felt, a passenger on Flight 93. (Gazarik 9/8/2002) Felt makes the 911 call using his cell phone. (9/11 Commission 8/26/2004, pp. 45; US District Court for the Eastern District of Virginia, Alexandria Division 7/31/2006) It is answered by dispatcher John Shaw, on a line at the center specifically for incoming cell phone calls. (Federal Bureau of Investigation 9/12/2001 pdf file; Longman 2002, pp. 193) Glenn Cramer, a supervisor at the 911 center, hears Shaw responding to the caller, “You are what hijacked?” and consequently picks up a phone that allows him to listen in on the rest of Felt’s call. (Federal Bureau of Investigation 9/12/2001 pdf file; Hoffman 12/7/2001)
Call Center Workers Mishear Name - Felt identifies himself. Shaw and Cramer apparently mishear, and both will recall that he says his name is “Ed Wart.” (Federal Bureau of Investigation 9/11/2001 pdf file; Federal Bureau of Investigation 9/12/2001 pdf file) (The FBI will initially refuse to disclose the caller’s name to the press, but he is later revealed to have been Edward Felt, a 41-year-old engineer from New Jersey. (Lane and Pan 9/12/2001; Longman 2002, pp. 194; Longman 3/27/2002) ) Felt says, “We are being hijacked, we are being hijacked!” He repeatedly states that his call is not a hoax. (ABC News 9/11/2001; Associated Press 9/11/2001) He says the passengers need help immediately. (Federal Bureau of Investigation 9/11/2001 pdf file)
Felt Answers Questions about His Flight, but Does Not Describe Hijackers - Shaw asks Felt standard questions, such as where is he? What type of plane is he on? And what has happened? (Pittsburgh Post-Gazette 9/11/2002) Felt tells Shaw his cell phone number and says he is on United Airlines Flight 93 from Newark to San Francisco. (Longman 2002, pp. 193-194; Frederick 9/11/2002; United States of America v. Zacarias Moussaoui, a/k/a Shaqil, a/k/a Abu Khalid al Sahrawi, Defendant. 4/11/2006 pdf file) He says he is locked in the bathroom of the plane, but does not say if this is its front or rear bathroom. He does not say anything about how many hijackers are on board, nor make any statements about any weapons the hijackers may possess. (Federal Bureau of Investigation 9/12/2001 pdf file) Nor does he mention any attempt by the passengers to regain control of the plane. (Longman 2002, pp. 196)
Felt Describes 'Lots of Passengers,' though Plane Is Mostly Empty - Shaw will recall to the FBI that Felt tells him the plane is loaded with numerous passengers. (Federal Bureau of Investigation 9/11/2001 pdf file) Glenn Cramer will similarly tell the FBI that Felt describes “lots of passengers” on board. (Federal Bureau of Investigation 9/12/2001 pdf file) Yet there are only 37 passengers (including the four hijackers) on Flight 93, constituting just 20 percent of its passenger capacity of 182. (9/11 Commission 8/26/2004, pp. 36) Felt says: “We’re going down. We’re going down.” (Longman 3/27/2002; Frederick 9/11/2002) Cramer will say that Felt describes an explosion on the aircraft and smoke coming from it, but others—including Shaw—will deny this (see (Between 9:58 a.m. and 9:59 a.m.) September 11, 2001). (Associated Press 9/11/2001; Federal Bureau of Investigation 9/12/2001 pdf file; Longman 2002, pp. 264; Biedka 9/11/2002)
Call Ends after One Minute - Shaw will tell the FBI the call lasts “less than five minutes” before the line disconnects. (Federal Bureau of Investigation 9/11/2001 pdf file) According to other accounts, it lasts just over one minute. (Wagner and McCall 9/12/2001; Longman 2002, pp. 197; Gazarik 9/8/2002; Biedka 9/11/2002) After the call ends, other employees at the Westmoreland County 911 center are instructed to notify the FBI and the FAA about it. (Federal Bureau of Investigation 9/12/2001 pdf file) When the FBI arrives at the center, it will immediately take possession of the tape of Felt’s call. (Lane and Pan 9/12/2001; Bunch 11/15/2001)

[Source: John Labriola]In the lobby of Building 7 of the WTC, EMS Division Chief John Peruggia is in discussion with Fire Department Captain Richard Rotanz and a representative from the Department of Buildings. As Peruggia later describes, “It was brought to my attention, it was believed that the structural damage that was suffered to the [Twin] Towers was quite significant and they were very confident that the building’s stability was compromised and they felt that the North Tower was in danger of a near imminent collapse.” Peruggia grabs EMT Richard Zarrillo and tells him to pass on the message “that the buildings have been compromised, we need to evacuate, they’re going to collapse.” Zarrillo heads out to the fire command post, situated in front of 3 World Financial, the American Express Building, where he relays this message to several senior firefighters. He says, “OEM says the buildings are going to collapse; we need to get out.” (OEM is the Mayor’s Office of Emergency Management, which has its headquarters in WTC 7.) Fire Chief Pete Ganci’s response is, “who the f___ told you that?” Seconds later, they hear the noise of the South Tower as it collapses. (Turi 10/23/2001; Peruggia 10/25/2001; Zarrillo 10/25/2001; Fortis 11/9/2001) Others also appear to have been aware of the imminent danger. Fire Chief Joseph Pfeifer, who is at the command post in the lobby of the North Tower, says, “Right before the South Tower collapsed, I noticed a lot of people just left the lobby, and I heard we had a crew of all different people, high-level people in government, everybody was gone, almost like they had information that we didn’t have.” He says some of them are moving to a new command post across the street. (Pfeifer 10/23/2001; Firehouse Magazine 4/2002; Dwyer and Flynn 2005, pp. 214) Mayor Giuliani also says he receives a prior warning of the first collapse, while at his temporary headquarters at 75 Barclay Street (see (Before 9:59 a.m.) September 11, 2001).

[Source: Family photo]CeeCee Lyles says to her husband, “Aah, it feels like the plane’s going down.” Her husband Lorne says, “What’s that?” She replies, “I think they’re going to do it. they’re forcing their way into the cockpit” (an alternate version says, “they’re getting ready to force their way into the cockpit”). A little later she screams, then says, “they’re doing it! they’re doing it! they’re doing it!” Her husband hears more screaming in the background, then he hears a “whooshing sound, a sound like wind,” then more screaming, and then the call breaks off. (Hillston 10/28/2001; Pittsburgh Post-Gazette 10/28/2001; Longman 2002, pp. 180)

Since around 9:54, Flight 93 passenger Elizabeth Wainio has been speaking by phone with her stepmother Esther Heymann (see (9:54 a.m.) September 11, 2001). (9/11 Commission 8/26/2004, pp. 44) Wainio ends her call saying, “They’re getting ready to break into the cockpit. I have to go. I love you. Good-bye.” She then hangs up. (Longman 2002, pp. 172) The 9/11 Commission concludes that the passengers’ revolt against the hijackers that Wainio is referring to begins at 9:57 a.m. (9/11 Commission 8/26/2004, pp. 45) Yet according to journalist and author Jere Longman, Wainio’s call lasts 11 minutes, and ends at “just past ten” o’clock, which is several minutes after the revolt starts. (Longman 2002, pp. 171-172) In fact, if Wainio’s call began around 9:54, as is officially claimed, and lasts 11 minutes, it would end around 10:05. This is after official accounts claim Flight 93 crashed, but before the crash time of 10:06 later provided by an analysis of seismic records (see (10:03 a.m.-10:10 a.m.) September 11, 2001). However, according to the 9/11 Commission and a summary of passenger phone calls presented at the 2006 Zacarias Moussaoui trial, Wainio’s call only lasts four-and-a-half minutes. This would mean it ends just shortly after the passenger revolt begins.

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

According to an emergency call center supervisor who listens in on the call, when passenger Edward Felt phones 911 from Flight 93 to report that his plane has been hijacked, he says he has heard an explosion and sees smoke coming from the plane. But others will explicitly deny this. (Associated Press 9/11/2001; Longman 3/27/2002) Felt called 911 on his cell phone at 9:58 a.m., and talks to a dispatcher at the 911 center in Westmoreland County, Pennsylvania (see 9:58 a.m. September 11, 2001). (Longman 2002, pp. 193; 9/11 Commission 8/26/2004, pp. 45)
Said to Mention Explosion - Glenn Cramer, a supervisor at the center, listens in on the call on a separate line. The following day, he will tell the FBI that Felt said “some sort of explosion had occurred aboard the aircraft,” and “that there was white smoke somewhere on the plane.” (Federal Bureau of Investigation 9/12/2001 pdf file; Hoffman 12/7/2001) Cramer will similarly tell the Pittsburgh Post-Gazette that Felt said he “did hear some sort of an explosion and saw white smoke coming from the plane, but he didn’t know where.” (Silver et al. 9/12/2001) Some people will later cite this account as evidence that Flight 93 was shot down by the military to prevent it reaching its target, or was brought down when a bomb on board went off. (Bunch 11/15/2001; Longman 3/27/2002; Carlin 8/13/2002; Wallace 9/12/2002; Bunch 9/16/2002)
Account Disputed - However, others dispute Cramer’s account. John Shaw, the dispatcher who Felt talks to, will apparently make no mention of Felt reporting an explosion or smoke when he is interviewed by the FBI later in the day. (Federal Bureau of Investigation 9/11/2001 pdf file) And, in 2002, Shaw will state specifically that Felt made no mention of any explosion or smoke. “Didn’t happen,” he will say. Sandra Felt, the wife of Edward Felt, will hear the recording of the 911 call and subsequently also say her husband did not mention an explosion or smoke. (Longman 2002, pp. 264; Longman 3/27/2002; Levin 4/21/2002; Biedka 9/11/2002) Authorities will not explain Cramer’s contradictory account, and in September 2002 Britain’s Daily Mirror will report, “Glenn Cramer has now been gagged by the FBI.” (Bunch 11/15/2001; Wallace 9/12/2002)

According to New York City Mayor Rudolph Giuliani’s 9/11 Commission testimony in 2004, about one minute before the first WTC tower falls, he is able to reach the White House by phone. Speaking to Chris Henick, deputy political director to President Bush, Giuliani learns the Pentagon has been hit and he asks about fighter cover over New York City. Henick replies, “The jets were dispatched 12 minutes ago and they should be there very shortly, and they should be able to defend you against further attack.” (9/11 Commission 5/19/2004) If this is true, it means fighters scramble from the Otis base around 9:46 a.m., not at 8:52 a.m., as most other accounts have claimed. While Giuliani’s account may seem wildly off, it is consistent with reports shortly after 9/11. In the first few days, acting Joint Chiefs of Staff Chairman Richard Myers, and a NORAD spokesman, Marine Corps Major Mike Snyder, claimed no fighters were scrambled anywhere until after the Pentagon was hit. (US Congress 9/13/2001; Johnson 9/15/2001) This story only changed on the evening of September 14, 2001, when CBS reported, “contrary to early reports, US Air Force jets did get into the air on Tuesday while the attacks were under way.” (CBS News 9/14/2001)

Some witnesses near the World Trade Center feel the ground shaking just before the South Tower starts to collapse:
bullet EMT Joseph Fortis is heading across West Street, when, he says, “the ground started shaking like a train was coming.” He then looks up and sees the South Tower starting to collapse. (Fortis 11/9/2001)
bullet Lonnie Penn, another EMT, is outside the Marriott Hotel, which is adjacent to the North Tower. He and his partner “felt the ground shake. You could see the towers sway and then it just came down.” (Penn 11/9/2001)
bullet Bradley Mann is at the EMS staging area on Vesey Street. He says, “Shortly before the first tower came down I remember feeling the ground shaking. I heard a terrible noise, and then debris just started flying everywhere.” (Mann 11/7/2001)
bullet Battalion Chief Brian O’Flaherty is walking into the lobby of the Marriott Hotel. He says, “I hear a noise. Right after that noise, you could feel the building start to shudder, tremble, under your feet.” He then hears the “terrible noise” of the South Tower collapsing. (O'Flaherty 1/9/2002) Witnesses will also notice the ground shaking before the North Tower collapses (see Shortly Before 10:28 a.m. September 11, 2001).

Lynne Cheney conferring with Dick Cheney in the early afternoon on 9/11.Lynne Cheney conferring with Dick Cheney in the early afternoon on 9/11. [Source: David Bohrer / White House]Vice President Dick Cheney, accompanied by his wife, enters the Presidential Emergency Operations Center (PEOC), a bunker below the East Wing of the White House, after being evacuated from his office by the Secret Service. (Thomas 12/30/2001; 9/11 Commission 7/24/2004, pp. 39-40) Secret Service agents hurried Cheney out of his office in the West Wing of the White House at around 9:36 a.m., according to some accounts (see (9:36 a.m.) September 11, 2001), although other accounts will suggest he was evacuated from there at around 9:03 a.m. (see (Shortly After 9:03 a.m.) September 11, 2001). (Safire 9/13/2001; ABC News 9/14/2002; 9/11 Commission 7/24/2004, pp. 39-40; Gellman 2008, pp. 115) Cheney paused in an underground tunnel leading to the PEOC (see (9:37 a.m.) September 11, 2001), where he talked on the phone with President Bush (see (9:45 a.m.-9:56 a.m.) September 11, 2001) and was joined by his wife, Lynne Cheney, after she arrived at the White House (see (9:55 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 40)
Cheney and Wife Go into Conference Room - After he finishes his call with the president, the vice president goes with his wife into the PEOC. (Cheney and Cheney 2011, pp. 2) They pass through a small communications studio and then turn left into a larger conference room. (Gellman 2008, pp. 116) There is “conflicting evidence” about when Cheney arrives in the conference room, according to the 9/11 Commission Report. The 9/11 Commission will conclude, however, that he enters it “shortly before 10:00, perhaps at 9:58.” (9/11 Commission 7/24/2004, pp. 40)
Cheney Now in a Position to 'Receive Reports' and 'Make Decisions' - In the middle of the conference room, according to journalist and author Stephen Hayes, “is a rectangular wood table, long enough to seat 16 people comfortably. At several places around the table, drawers contain a white telephone for secure communications. A second row of chairs along the wall provides room for support staff.” The vice president takes his place at the center of the table. (Hayes 2007, pp. 337-338) Cheney will describe: “On the wall across from me were two large television screens and a camera for videoconferencing. A side wall contained another video camera and two more TV screens.” (Cheney and Cheney 2011, pp. 2) He will comment that in the conference room, he is “in a position to be able to see all the stuff coming in, receive reports, and then make decisions in terms of acting with it.” (Cheney 9/16/2001)
Cheney Starts 'Working the Problem' - Cheney will recall that shortly after he enters the conference room, he watches the first World Trade Center tower collapsing on television (see 9:59 a.m. September 11, 2001). Then, he will say, he “plugged in and start[ed] working the phones and working the problem.” (Cheney 11/19/2001) A short time after he enters the PEOC, according to the 9/11 Commission Report, Cheney will talk over the phone with the president (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 40)

Large amounts of gold are stored in vaults in the massive basement below the WTC, and some of this is being transported through the basement this morning. Several weeks later, recovery workers will discover hundreds of ingots in a service tunnel below WTC 5, along with a ten-wheel lorry and some cars (which were, presumably, transporting the gold) (see (Mid-October-mid November 2001)). The lorry and cars had been crushed by falling steel, but no bodies will be reported found with them, so presumably they were abandoned before the first WTC collapse, at 9:59 a.m. (Gittrich, Zambito, and Standora 10/31/2001; Wapshott 11/1/2001)

National Security Adviser Condoleezza Rice enters the underground tunnel leading to the Presidential Emergency Operations Center (PEOC)—the bunker below the White House—where she encounters Vice President Dick Cheney, and then heads into the PEOC. Rice has been escorted down from the White House Situation Room by Carl Truscott, the Secret Service special agent in charge of the presidential protective division, who told her she had to go to the PEOC (see (9:45 a.m.) September 11, 2001). (United States Secret Service 10/1/2001; Rice 8/6/2002) Before she left the Situation Room, Rice briefly talked on the phone with President Bush (see (9:45 a.m.) September 11, 2001). (Rice 8/2/2002; Rice 8/6/2002)
Rice Meets Cheney in Underground Tunnel - When Rice and Truscott enter the underground tunnel that leads to the PEOC, they encounter Cheney and his wife, Lynne Cheney, along with one of Cheney’s Secret Service agents. (United States Secret Service 10/1/2001) Cheney was being taken to the PEOC by his Secret Service agents (see (9:36 a.m.) September 11, 2001, but stopped in an area of the underground tunnel where there is a secure telephone, in order to speak to Bush (see (9:37 a.m.) September 11, 2001 and (9:45 a.m.-9:56 a.m.) September 11, 2001). Lynne Cheney joined him there after she arrived at the White House (see (9:55 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 39-40) Cheney is still on the phone with Bush when Truscott and Rice meet him. Truscott advises the group assembled in the tunnel to move on to the PEOC. (United States Secret Service 10/1/2001)
Rice Heads into the PEOC - Rice subsequently goes from the tunnel into the PEOC, although the exact time when she does so is unclear. She enters the PEOC “shortly after the vice president,” according to the 9/11 Commission Report, which will state that Cheney arrives in the PEOC at around 9:58 a.m. (see (9:58 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 40) Rice must enter the PEOC before 9:59 a.m., since she is there at the time the South Tower of the World Trade Center collapses, as will be confirmed by a photo taken at that time (see 9:59 a.m. September 11, 2001). (Thomas 12/30/2001; Bumiller 2007, pp. xiii; Gellman and Becker 6/24/2007)
Rice Calls Relatives in Alabama - In the PEOC, Rice takes a seat next to Cheney. (9/11 Commission 7/24/2004, pp. 40; Bumiller 2007, pp. xiii) The first thing she does after arriving, according to some accounts, is call her aunt and uncle in Birmingham, Alabama, to tell them to inform her family that she is okay. (Rice 10/24/2001; O, the Oprah Magazine 2/1/2002; Rice 8/2/2002; Sanger 9/11/2002) But other accounts will say she called them just before she headed out from the Situation Room. (Rice 11/1/2001; Rice 8/7/2002; Associated Press 9/9/2002; Bumiller 2007, pp. xiii)

Will Jimeno.Will Jimeno. [Source: Todd Plitt / USA Today]Some witnesses reportedly see a massive fireball at ground level, coming from the South Tower just before it starts to collapse. According to a report by the Mineta Transportation Institute (a research institute founded by Transportation Secretary Norman Mineta), “People inside the South Tower felt the floor vibrate as if a small earthquake were occurring.… The vibration lasted for about 30 seconds. The doors were knocked out, and a huge ball of flame created by the exploding diesel fuel from the building’s own supply tank shot from the elevator shaft and out the doors of the South Tower, consuming everything in its path. Minutes later, at 9:59 a.m., the tower collapsed.” (Jenkins and Edwards-Winslow 9/2003, pp. 16 pdf file) Around the same time, Port Authority Police Officer Will Jimeno is in a corridor leading toward the North Tower. “Suddenly the hallway began to shudder,” and he sees “the giant fireball explode in the street,” when the South Tower begins to collapse. (James 1/2003) Ronald DiFrancesco is the last person to make it out of the South Tower before it collapses. As he is heading toward the exit that leads onto Church Street, he hears a loud roar as the collapse begins. According to the Ottawa Citizen, “Mr. DiFrancesco turned to his right in the direction of Liberty Street, to see a massive fireball—compressed as the South Tower fell—roiling toward [him].” He bolts for the exit, before being knocked unconscious and blown many yards across the street. (Cauchon 12/18/2001; Duffy 6/4/2005; Duffy 6/5/2005; Clark 9/5/2006) A number of other witnesses report feeling the ground shaking just seconds before the South Tower collapses (see Shortly Before 9:59 a.m. September 11, 2001).

Employees at CIA headquarters are aware that Flight 93 is unaccounted for, and assume their building is its intended target. This is according to CIA contractor Billy Waugh, who is currently doing some work for the agency and is at its Langley headquarters at the time of the attacks. In a 2004 book, Waugh will describe: “We had witnessed the hits on the World Trade Center and knew the hijacked United Airlines Flight 93 remained unaccounted for. It was a widespread assumption within the building that this flight was headed straight for us in the CIA headquarters.” (Waugh and Keown 2004, pp. 293-294) At around 10:00 a.m., much of CIA headquarters is evacuated, following reports of unresponsive aircraft possibly heading toward Washington (see (9:50 a.m.-10:00 a.m.) September 11, 2001). (Tenet 2007, pp. 164) Waugh recalls, “There was no panic, just an understanding that those in my division needed to walk to the west parking lot, away from the buildings, and await the inevitable impact.” He adds that, “Upon hearing that Flight 93 had gone down in a Pennsylvania field, a couple of us returned to the HQ building to pick up any necessary gear.” (Waugh and Keown 2004, pp. 294) The 9/11 Commission will state that Flight 93’s intended target is either the Capitol building or the White House, not CIA headquarters. (9/11 Commission 7/24/2004, pp. 14) However, in 2006 MSNBC will note, “to this day, the ultimate target of the terrorists on this aircraft has never been confirmed.” (Shuster 9/12/2006)

Mayor Rudolph Giuliani will become well known for his walking press conferences in the middle of the 9/11 crisis.Mayor Rudolph Giuliani will become well known for his walking press conferences in the middle of the 9/11 crisis. [Source: Time Magazine/ Salient Stills]Between 9:25 a.m. and 9:45 a.m., one senior New York fire chief recommends to the Fire Department Chief of Department that there might be a WTC collapse in a few hours, and, therefore, fire units probably shouldn’t ascend much above the sixtieth floor (presumably this assumes the collapse would be gradual so those on lower floors would still have time to evacuate). This advice is not followed or not passed on. Apparently, no other senior fire chiefs mention or foresee the possibility of the WTC towers falling. (9/11 Commission 5/19/2004) However, New York City Mayor Rudolph Giuliani later recounts, “I went down to the scene and we set up headquarters at 75 Barclay Street, which was right there, with the police commissioner, the fire commissioner, the head of emergency management, and we were operating out of there when we were told that the World Trade Center was going to collapse. And it did collapse before we could actually get out of the building, so we were trapped in the building for ten, 15 minutes, and finally found an exit and got out, walked north, and took a lot of people with us.” (ABC News 9/11/2001) As can be seen by another account of similar events, this happens before the first WTC tower falls, not the second. (9/11 Commission 5/19/2004) It is not clear who tells Giuliani to evacuate when no fire chiefs were considering the possibility of an imminent collapse. However, an EMT is also given a message around this time, warning that the towers are going to collapse. The origin of this information is apparently the Mayor’s Office of Emergency Management, so this may also have been from where Giuliani heard of the imminent collapse (see (Before 9:59 a.m.) September 11, 2001).

Directly behind Cheney are Norman Mineta and I. Lewis ‘Scooter’ Libby. National Security Advisor Condoleezza Rice stands behind Cheney’s left shoulder. [Source: David Bohrer / White House]In the conference room of the Presidential Emergency Operations Center (PEOC), Vice President Cheney, National Security Adviser Condoleezza Rice, and their aides watch the South Tower collapsing on television. (Thomas 12/31/2001) Cheney will later say that the WTC coming down “was a shock to everybody—it certainly was to me.” (PBS 9/9/2002) However, if he is indeed shocked, this is not how Cheney appears to others in the room. One witness who is present will later recall that, as the South Tower collapses, there is “a groan in the room that I won’t forget, ever. It seemed like one groan from everyone.” However, Cheney makes no sound, but closes his eyes for a long, slow blink. The witness says, “I remember turning my head and looking at the vice president, and his expression never changed.” (Gellman and Becker 6/24/2007) According to Mary Matalin, a counselor to the vice president, Cheney says nothing in response to the collapse, but “he emoted in a way that he emotes, which was to stop.” (CNN 9/11/2002; CNN 9/11/2002) When he is told that a casualty estimate ranges well into the thousands, the vice president reportedly just nods grimly. (Thomas 12/31/2001) According to the Washington Post, three people who are present say they see no sign now or later “of the profound psychological transformation that has often been imputed to Cheney.” What they see is “extraordinary self-containment and a rapid shift of focus to the machinery of power. While others assessed casualties and the work of ‘first responders,’ Cheney began planning for a conflict that would call upon lawyers as often as soldiers and spies.” He will promptly begin assembling the legal team that subsequently assists him in expanding presidential power (see (After 10:00 a.m.) September 11, 2001). (Gellman and Becker 6/24/2007)

According to Lyz Glick, as recounted in the book “Among the Heroes,” she is speaking to her husband Jeremy Glick on Flight 93 when he tells her that passengers have been hearing from other phone calls that planes are crashing into the World Trade Center. He asks her, “Are [the hijackers] going to blow this plane up?” Lyz replies that she doesn’t know, but tells him that it is true two planes have crashed into the World Trade Center. He asks her if they’re going to crash the plane into the World Trade Center. She replies, “No. They’re not going there.” He asks why, and she replies that one of the towers has just fallen. “They knocked it down.” The first World Trade Center tower collapses at 9:59 and is seen by millions on television. The book makes clear that this exchange takes place at “almost ten o’clock” —within a minute of the tower collapse. (Longman 2002, pp. 147) This account contradicts the 9/11 Commission’s conclusion that the passenger assault on the cockpit begins at 9:58, because the tower collapse was definitely at 9:59. Only later in the same phone call does Jeremy Glick mention that passengers are still taking a vote on whether or not to attack the hijackers. He confers with others and tells Lyz that they’ve decided to do so, and then gets off the phone line. (Longman 2002, pp. 153-54)

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). (Clarke 2004, pp. 7-8)

Deputy Fire Commissioner Thomas Fitzpatrick.Deputy Fire Commissioner Thomas Fitzpatrick. [Source: City of New York]Numerous witnesses to the collapse of the south WTC tower think it resembles a demolition using explosives. Some initially believe this is what is occurring:
bullet Reporter John Bussey watches the collapse from the Wall Street Journal’s offices across the street from the WTC. He says, “I… looked up out of the office window to see what seemed like perfectly synchronized explosions coming from each floor, spewing glass and metal outward. One after the other, from top to bottom, with a fraction of a second between, the floors blew to pieces.” (Bussey 9/12/2001)
bullet Deputy Fire Commissioner Thomas Fitzpatrick: “I remember seeing, it looked like sparkling around one specific layer of the building.… Then the building started to come down. My initial reaction was that this was exactly the way it looks when they show you those implosions on TV.” (Fitzpatrick 10/1/2001)
bullet Assistant Fire Commissioner Stephen Gregory: “I saw low-level flashes. In my conversation with Lieutenant Evangelista… he questioned me and asked me if I saw low-level flashes in front of the building, and I agreed with him… I saw a flash flash flash and then it looked like the building came down.… You know like when they demolish a building, how when they blow up a building, when it falls down? That’s what I thought I saw.” (Gregory 10/3/2001)
bullet Firefighter Richard Banaciski: “It seemed like on television they blow up these buildings. It seemed like it was going all the way around like a belt, all these explosions.” (Banaciski 12/6/2001)
bullet Firefighter Joseph Meola: “As we are looking up at the building, what I saw was, it looked like the building was blowing out on all four sides. We actually heard the pops.… You thought it was just blowing out.” (Meola 12/11/2001)
bullet Fire Chief Frank Cruthers: “[T]here was what appeared to be at first an explosion. It appeared at the very top, simultaneously from all four sides, materials shot out horizontally. And then there seemed to be a momentary delay before you could see the beginning of the collapse.” (Cruthers 10/31/2001)
bullet Battalion Chief Brian Dixon: “I was watching the fire… the lowest floor of fire in the South Tower actually looked like someone had planted explosives around it because the whole bottom I could see—I could see two sides of it and the other side—it just looked like that floor blew out.… I thought, geez, this looks like an explosion up there, it blew out.” (Dixon 10/25/2001)
bullet Firefighter Timothy Burke: “Then the building popped, lower than the fire… I was going oh, my god, there is secondary device because the way the building popped I thought it was an explosion.” (Burke 1/22/2002)
bullet Firefighter Edward Cachia: “It actually gave at a lower floor, not the floor where the plane hit, because we originally had thought there was like an internal detonation explosives because it went in succession, boom, boom, boom, boom, and then the tower came down.” (Cachia 12/6/2001)
bullet Firefighter Kenneth Rogers: “[T]here was an explosion in the South Tower… I kept watching. Floor after floor after floor. One floor under another after another and when it hit about the fifth floor, I figured it was a bomb, because it looked like a synchronized deliberate kind of thing.” (Rogers 12/10/2001)
bullet Reporter Beth Fertig: “The tower went down perfectly straight, as if a demolition crew had imploded it. I wondered if it was being brought down deliberately.” (Gilbert et al. 2002, pp. 78)
bullet Paramedic Daniel Rivera: “[D]o you ever see professional demolition where they set the charges on certain floors and then you hear ‘Pop, pop, pop, pop, pop’? That’s exactly what—because I thought it was that.” (Rivera 10/10/2001)
bullet Battalion Chief Dominick DeRubbio: “It was weird how it started to come down. It looked like it was a timed explosion.” (DeRubbio 10/12/2001)
bullet The Guardian will report that police on the scene said the collapse “looked almost like a ‘planned implosion’ designed to catch bystanders watching from the street.” (Borger et al. 9/12/2001)
However, the National Institute of Standards and Technology, which conducts a three-year study of the WTC collapses, will reject suggestions that the WTC towers were brought down with explosives (see August 30, 2006). CTV will assert, “[F]lashes of light that seemed to indicate bombs detonating were not explosions. They were pockets of airs being forced out of windows as the sagging floors pushed downward.” (Stittle 9/12/2006)

JFK International Airport.JFK International Airport. [Source: Eheik, via Wikimedia Commons]The two F-15 fighter jets launched from Otis Air National Guard Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) are about 15 miles from the World Trade Center, flying over New York’s JFK International Airport, when the first WTC tower collapses. (Dennehy 8/21/2002; Duffy 10/22/2002; Walling 2015, pp. 12) From 9:09 a.m. to 9:13 a.m., the fighters flew in a “holding pattern” in military-controlled airspace over the Atlantic Ocean (see 9:09 a.m.-9:13 a.m. September 11, 2001). At 9:13 a.m., they left their holding pattern and flew directly toward Manhattan (see 9:13 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 20, 24) However, the fighters are 15 miles away from the WTC 46 minutes later, when the South Tower collapses (see 9:59 a.m. September 11, 2001). (Dennehy 8/21/2002) “When the first tower collapsed, we were headed away from Manhattan over [JFK Airport],” Major Daniel Nash, the pilot of one of the fighters, will later recall. (Nash 10/2/2002) “When we turned around, all we saw was Lower Manhattan covered in dust and debris,” he will say. (Dennehy 8/21/2002) The other fighter is escorting a Delta Air Lines plane into JFK Airport at this time. Lieutenant Colonel Timothy Duffy, its pilot, will recall that as he is escorting the plane, “I just remember seeing some, some motion out of the corner of my eye and all I could see was a tan cloud that was over southern Manhattan.” (Shawn 9/8/2011; Corcoran 9/9/2011) Duffy says to Nash over the radio, “It looks like the building collapsed.” Nash thinks, “There were just tens of thousands of people killed.” “I thought it was the start of World War III,” he will comment. (Dennehy 8/21/2002) The two Otis fighters arrived over Manhattan at 9:25 a.m., according to the 9/11 Commission Report (see 9:25 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 24) However, the accounts of numerous witnesses on the ground will indicate that they arrive over Manhattan sometime after 10:00 a.m. (see (9:45 a.m.-10:45 a.m.) September 11, 2001).

[Source: Smithsonian National Museum of American History]After Flight 93 passenger Todd Beamer has finished speaking to GTE customer service supervisor Lisa Jefferson (see Shortly Before 9:58 a.m. September 11, 2001), he puts down the seatback phone he has been talking on but leaves the line connected. Jefferson continues listening until after the time the plane crashes, yet does not hear any sound when the crash occurs. As she later recalls, “I was still on the line and the plane took a dive and by then, it just went silent. I held on until after the plane crashed—probably about 15 minutes longer and I never heard a crash—it just went silent because—I can’t explain it. We didn’t lose a connection because there’s a different sound that you use. It’s a squealing sound when you lose a connection. I never lost connection, but it just went silent.” She says that soon afterwards, “they had announced over the radio that United Airlines Flight 93 had just crashed in Shanksville, Pennsylvania, and a guy put his hand on my shoulder and said, ‘Lisa, you can release the line now. That was his plane.‘… [E]ventually I gave in and I hung the phone up.” (Jefferson 2006) According to a summary of the passenger phone calls presented at the 2006 trial of Zacarias Moussaoui, Beamer’s call lasts for “3,925 seconds.” As it began just before 9:44 a.m., this would mean it ends around 10:49 a.m. (US District Court for the Eastern District of Virginia, Alexandria Division 7/31/2006)

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

Numerous witnesses, including firefighters and other rescue workers, hear explosions at the start of, and during, the collapse of the south WTC tower. Some of them report hearing a single explosion:
bullet Jeff Birnbaum: “There was an explosion and the whole top leaned toward us and started coming down.” (Lucy 2/1/2002)
bullet Battalion Chief John Sudnik: “[W]e heard a loud explosion or what sounded like a loud explosion and looked up and I saw Tower Two start coming down.” (Sudnik 11/7/2001)
bullet Firefighter Edward Kennedy hears “a tremendous boom, explosion… and the top of the building was coming down at us.” (Kennedy 1/17/2002)
bullet Firefighter Edward Sheehey hears “an explosion, looked up, and the building started to collapse.” (Sheehey 12/4/2001)
bullet Battalion Chief Thomas Vallebuona: “I heard ‘boom,’ an exploding sound, a real loud bang. I looked up, and I could see the Trade Center starting to come down.” (Vallebuona 1/2/2002)
bullet EMT Julio Marrero: “I heard a loud bang. We looked up, and we just saw the building starting to collapse.” (Marrero 10/25/2001)
Other witnesses report hearing multiple explosions:
bullet Journalist Pete Hamill: “We heard snapping sounds, pops, little explosions, and then the walls bulged out, and we heard a sound like an avalanche.” (Hamill 9/11/2001)
bullet Police officer Sue Keane, who is an Army veteran, is located in the north WTC tower: “[I]t sounded like bombs going off. That’s when the explosions happened.… It started to get dark, then all of a sudden there was this massive explosion.” (Hagen and Carouba 2002, pp. 65)
bullet Firefighter Keith Murphy, who is in the lobby of the North Tower: “[T]he first thing that happened, which I still think is strange to me, the lights went out.… I had heard right before the lights went out, I had heard a distant boom boom boom, sounded like three explosions.… At the time, I would have said they sounded like bombs, but it was boom boom boom and then the lights all go out.… I would say about 3, 4 seconds, all of a sudden this tremendous roar.” (Murphy 12/5/2001)
bullet Firefighter Craig Carlsen hears “explosions coming from building two, the South Tower. It seemed like it took forever, but there were about ten explosions.… We then realized the building started to come down.” (Carlsen 1/25/2002)
bullet Firefighter Thomas Turilli, who is in the lobby of the North Tower: “[A]ll of a sudden you just heard like it almost actually that day sounded like bombs going off, like boom, boom, boom, like seven or eight, and then just a huge wind gust just came… It just seemed like a huge explosion.” (Turilli 1/17/2002)
bullet Firefighter Stephen Viola: “[T]hat’s when the South Tower collapsed, and it sounded like a bunch of explosions. You heard like loud booms.” (Viola 1/10/2002)
bullet Firefighter Lance Lizzul: “[W]e heard some bangs. That made us look up, and that’s when the first Trade Center came down.” (Lizzul 12/10/2001)
bullet Paramedic Kevin Darnowski: “I heard three explosions, and then we heard like groaning and grinding, and Tower Two started to come down.” (Darnowski 11/9/2001)
However, the National Institute of Standards and Technology, which conducts a three-year study of the WTC collapses, will subsequently claim it found “no corroborating evidence for alternative hypotheses suggesting that the WTC towers were brought down by controlled demolition using explosives” (see October 26, 2005). (National Institute of Standards and Technology 9/2005, pp. 146)

An F-16 flies over New York City on September 12, 2001. Smoke is still rising from the World Trade Center. [Source: Air National Guard]An air traffic controller at the FAA’s New York Center radios the pilots launched from Otis Air National Guard Base in response to Flight 11 (see 8:46 a.m. September 11, 2001) and tells them they may have to take out a hijacked aircraft. One of the two Otis pilots, Major Daniel Nash, will later recall, “The New York controller did come over the radio and say if we have another hijacked aircraft we’re going to have to shoot it down.” (BBC 9/1/2002) However, he will add that this is just “an off-the-cuff statement.” (Dennehy 8/21/2002) It is unclear at what time this communication occurs, though a BBC documentary will place it at about the time the South Tower collapses, which would be around 9:59 a.m. (BBC 9/1/2002) NORAD’s Northeast Air Defense Sector (NEADS) has already radioed one of the Otis pilots to check that he is prepared to shoot down a hijacked aircraft (see (9:35 a.m.) September 11, 2001). (Spencer 2008, pp. 153) But according to most accounts, the two pilots never receive an order from the military to shoot down hostile aircraft (see (After 9:35 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 43; Viser 9/11/2005)

Counterterrorism “tsar” Richard Clarke is told in private by Dale Watson, the head of the FBI’s Counterterrorism Division: “We got the passenger manifests from the airlines. We recognize some names, Dick. They’re al-Qaeda.” Clarke asks, “How the f_ck did they get on board then?” Watson replies: “Hey, don’t shoot the messenger, friend. CIA forgot to tell us about them.” As they are talking about this, they see the first WTC tower collapse on television. (Clarke 2004, pp. 13-14) Some hijacker names, including Mohamed Atta’s, were identified on a reservations computer over an hour earlier (see (Shortly After 8:32 a.m.) September 11, 2001).

Logo of the 148th Fighter Wing.Logo of the 148th Fighter Wing. [Source: Air National Guard]Although the White House has requested a fighter escort for Air Force One (see 9:59 a.m. September 11, 2001), fighter jets that are kept on alert at Tyndall Air Force Base in Florida reportedly fail to launch in order to accompany the president’s plane after it takes off from Sarasota, Florida (see 9:54 a.m. September 11, 2001). (Filson 2003, pp. 87; Martin 7/4/2004; 9/11 Commission 7/24/2004, pp. 38)
Fighters on 'Battle Stations' but Not Launched - The 148th Fighter Wing of the Minnesota Air National Guard has a full time active duty detachment at Tyndall Air Force Base, near Panama City. (Filson 1999; US Air Force 2004; GlobalSecurity (.org) 8/21/2005) This unit serves as one of NORAD’s seven “alert” sites around the US, which all have a pair of fighter jets on the runway, armed, fueled, and ready to take off within minutes if called upon. (McKenna 12/1999; Hebert 2/2002; Kelly 12/5/2003) But, according to the 1st Air Force’s book about 9/11, although NORAD’s Southeast Air Defense Sector (SEADS) puts the alert jets at Tyndall on “battle stations,” it does not launch them. The jets’ pilots sit “in their cockpits awaiting word to go, but Air Force One moved so quickly they were never scrambled.” Instead, F-16s from Ellington Field in Texas are scrambled, and escort Air Force One to Barksdale Air Force Base (see (After 9:56 a.m.) September 11, 2001 and (11:29 a.m.) September 11, 2001). (Filson 2003, pp. 87) However, in a 2002 interview, Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will claim that after NORAD is told “just to follow the president” on Air Force One, it “scrambled available airplanes from Tyndall and then from Ellington in Houston, Texas. The Ellington F-16s chased Air Force One and landed with the president at Barksdale AFB in Louisiana.” (Code One Magazine 1/2002)
Other Alert Fighters in Florida Not Launched - NORAD also keeps two fighters on alert at Homestead Air Reserve Base, near Miami, Florida, but it is unclear whether these are scrambled after Air Force One, and apparently they never accompany the president’s plane (see (10:00 a.m.) September 11, 2001). Philip Melanson, an expert on the Secret Service, will later comment: “I can’t imagine by what glitch the protection was not provided to Air Force One as soon as it took off. I would have thought there’d be something in place whereby one phone call from the head of the security detail would get the fighters in the air immediately.” (Filson 2003, pp. 87; Martin 7/4/2004)

Ian Sanderson.Ian Sanderson. [Source: Rome Sentinel]Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), complains about Lieutenant Colonel Ian Sanderson—an officer from the NEADS battle cab—spending time on the operations floor, where, Nasypany says, he has been “circumventing my system.” (North American Aerospace Defense Command 9/11/2001) Sanderson is the NEADS Sector Operations Control Center (SOCC) director. He is also beginning his training as a fighter director on this day. (9/11 Commission 10/29/2003 pdf file) He is one of a number of senior personnel working in the battle cab, which is a glass-walled room overlooking the NEADS operations floor. (Filson 2003, pp. 55; 9/11 Commission 10/30/2003 pdf file) However, he has also been spending time on the operations floor.
Director Is 'Circumventing My System' - Nasypany therefore now complains, “Got to get Ian [Sanderson] off the floor.” He adds that Sanderson has been “on it, circumventing my system here.” (North American Aerospace Defense Command 9/11/2001) (As the mission crew commander (MCC), Nasypany is supposed to be in charge of the entire operations floor. (Spencer 2008, pp. 25) ) He continues with his complaint, saying that Sanderson is “not an MCC” and so he “needs to stay up there” in the battle cab. (North American Aerospace Defense Command 9/11/2001)
Director Says He 'Did Not Interfere' - Despite Nasypany’s grievance that he has been “circumventing my system,” Sanderson will tell the 9/11 Commission that his “first inclination” after the first World Trade Center tower was hit had been to “step back and let everyone do their jobs.” He will say that in “wartime”—presumably referring to situations like the present crisis—“there really is no function for the SOCC director.” His role on this day is therefore, partly, “to stay out of everyone’s way.” Sanderson will also say he is “parental” to the NEADS personnel, and, in contrast with Nasypany’s complaint about him, will say he “did not interfere.”
Director Responsible for Recalling Off-Duty Personnel - The SOCC director, according to Sanderson, serves as “an internal look at the operations on the SOCC [operations] floor,” and “involves manning and procedures of floor operations.” On this day, Sanderson is responsible for ensuring that the operations floor has additional personnel, and for coordinating fighter jets from bases that are not NORAD assets. Sanderson will say he is “primarily concerned with calling back the operations personnel” who are off duty. (9/11 Commission 10/29/2003 pdf file)

An F-15 Eagle from the 125th Fighter Wing.An F-15 Eagle from the 125th Fighter Wing. [Source: Shaun Withers / US Air Force]Fighter jets belonging to a military unit in Jacksonville, Florida, launch to escort Air Force One after it takes off from Sarasota, Florida (see 9:54 a.m. September 11, 2001), some accounts will later indicate. (Sanger and van Natta 9/16/2001; Langley 12/16/2001) However, other accounts will indicate that these jets, if launched, never reach the president’s plane. (Code One Magazine 1/2002; Kohn 9/11/2002; Spencer 2008, pp. 255)
Fighters Reportedly Launched - The New York Times will report that at 10:41 a.m., Air Force One is “headed toward Jacksonville to meet jets scrambled to give the presidential jet its own air cover.” (Sanger and van Natta 9/16/2001) And, according to a report in the Daily Telegraph, after Air Force One climbs to 40,000 feet, it is “joined by an escort of F-16 fighters from a base near Jacksonville.” (Langley 12/16/2001) These reports are presumably referring to jets belonging to the 125th Fighter Wing, a unit of the Florida Air National Guard located at Jacksonville International Airport. The wing keeps two F-15s on alert at Homestead Air Reserve Base, near Miami, ready for immediate takeoff, as part of NORAD’s air sovereignty mission. (McKenna 12/1999; GlobalSecurity (.org) 8/21/2005; Florida Air National Guard 2009)
Fighters Likely Launched from Homestead - If 125th Fighter Wing jets are scrambled to accompany Air Force One, it appears they would be the unit’s F-15s on alert at Homestead, rather than its fighters at Jacksonville Airport. Major Charles Chambers, who is at the National Military Command Center at the Pentagon, will state within a week of the attacks, “Fighters had been scrambled from Homestead [Air Reserve Base] and were escorting Air Force One westward.” (US Department of Defense 9/2001) In contrast, at Jacksonville International Airport, according to a 2007 report in the Florida Times-Union, “Within hours of the 2001 terrorist attacks, the wing’s aircraft were sitting on a JIA runway ready for the order to scramble.” (Brumley 9/15/2007) And an account published by the Florida Air National Guard will only say, “On Sept. 11, 2001, several loaded F-15 aircraft lined Runway 13/31 [at Jacksonville Airport] for the first time in history.” (Guard 2007 pdf file)
Fighters Apparently Do Not Reach Air Force One - Most accounts will contradict Chambers’ claim that, if indeed 125th Fighter Wing jets are scrambled toward the president’s plane, they are subsequently “escorting Air Force One westward.” According to the 1st Air Force’s book about 9/11, it is in fact “[f]our F-16s from the 147th Fighter Wing, Texas Air National Guard,” that accompany Air Force One “from the panhandle of Florida to Barksdale Air Force Base.” (Filson 2003, pp. 87) CBS News will report that the first fighters to reach Air Force One are two F-16s from the 147th Fighter Wing (see (11:29 a.m.) September 11, 2001). (Kohn 9/11/2002; Spencer 2008, pp. 255) And Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will only say that 147th Fighter Wing F-16s “chased Air Force One and landed with the president at Barksdale AFB in Louisiana,” making no mention of any 125th Fighter Wing jets being scrambled. (Code One Magazine 1/2002) At NORAD’s other alert site in Florida besides Homestead—a unit at Tyndall Air Force Base—the two alert fighters are put on “battle stations,” but apparently do not take off to escort Air Force One (see (10:00 a.m.) September 11, 2001). (Filson 2003, pp. 87)

Jay Kopstein.Jay Kopstein. [Source: Jay Kopstein]Richard Ohlsen, an employee at the Federal Emergency Management Agency (FEMA) Region II office in Lower Manhattan, goes to the headquarters of the New York Police Department (NYPD), but is initially denied entry into the building and, once inside, experiences various difficulties as he tries to respond to the terrorist attacks. Following the second crash at the World Trade Center, the FEMA office was unable to communicate with Office of Emergency Management personnel in WTC Building 7 and so Ohlsen was told to go to WTC 7 to act as a liaison there (see (After 9:03 a.m.) September 11, 2001). As he was on his way out, though, the South Tower of the WTC collapsed (see 9:59 a.m. September 11, 2001).
FEMA Employee Is Denied Entry into the Police Headquarters - Consequently, instead of going to the WTC site, Ohlsen heads to the command center at NYPD headquarters, at One Police Plaza. When he arrives at NYPD headquarters, however, officers refuse to let him in because they do not recognize his FEMA identification as being official. Fortunately, Jay Kopstein, an inspector with the NYPD who happens to be passing by, recognizes him and takes him up to the command center.
Employee Lacks Priority Access to the Phone Network - Ohlsen’s problems continue, however, after he arrives there. Ohlsen does not have with him a special GETS (Government Emergency Telecommunications Service) phone card, which gives government and emergency workers priority to make phone calls during a crisis. Consequently, when he wants to reach FEMA headquarters in Washington, DC, he has to contact it through the normal collect call procedures, even though this is a national emergency. And when he does get through, he is told that responsibility for dealing with the attacks in New York has been transferred to FEMA’s Region I office in Massachusetts, as part of the agency’s standard continuity of operations procedures, and so all requests are meant to go through there.
Officials Refuse to Open an Equipment Cache - Ohlsen also runs into difficulty when he asks for an equipment cache that contains personal protective gear and search and rescue equipment for New York City’s urban search and rescue team to be opened. He is incredulous when, in light of the current situation, officials with the New York City Fire Department, which maintains the cache, refuse his request, supposedly because no one from the federal government has authorized the use of the equipment. Ohlsen apparently persists and eventually gets the cache opened, since he will later describe this setback as “the first problem he was able to resolve” after arriving at the command center. (9/11 Commission 3/16/2004 pdf file; Graff 2017, pp. 343-344)

Just after President Bush authorizes the military to shoot down threatening aircraft, he speaks with Secretary of Defense Donald Rumsfeld about this, according to some accounts. According to the Washington Post, Bush gave the shootdown authorization after taking off on Air Force One (see (Shortly After 9:56 a.m.) September 11, 2001). He then talks “to Rumsfeld to clarify the procedures military pilots should follow in trying to force an unresponsive plane to the ground before opening fire on it. First, pilots would seek to make radio contact with the other plane and tell the pilot to land at a specific location. If that failed, the pilots were to use visual signals. These included having the fighters fly in front of the other plane. If the plane continued heading toward what was seen as a significant target with apparently hostile intent, the US pilot would have the authority to shoot it down.” (Balz and Woodward 1/27/2002) Journalist and author Bill Sammon will give a similar account, saying that, having spoken with Vice President Dick Cheney soon after Air Force One took off, Bush “then explained the shootdown order to Donald Rumsfeld, who was at the still-burning Pentagon.” (Sammon 2002, pp. 102) The 9/11 Commission will concur that the “president apparently spoke to Secretary Rumsfeld for the first time… shortly after 10:00.” However, contradicting earlier accounts, it will say, “No one can recall the content of this conversation, but it was a brief call in which the subject of shootdown authority was not discussed” (see (10:00 a.m.-10:30 a.m.) September 11, 2001). According to the Commission, furthermore, the phone call between Bush and Cheney where the president gives the shootdown authorization is not until 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 41 and 43) Bush’s senior adviser Karl Rove, who is on Air Force One with the president, will also say this critical call occurs “at about 10:20,” and add that, after it, Bush reports that he has just talked to Rumsfeld as well as Cheney. (Rove 9/11/2002) Rumsfeld will indicate he first learns that shootdown authorization has been given from Cheney rather than Bush, telling the 9/11 Commission that the vice president “informed me of the president’s authorization to shoot down hostile aircraft” over the air threat conference call. (9/11 Commission 3/23/2004) The conversation he is referring to does not occur until 10:39 a.m. (see 10:39 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 43)

Someone falling from the WTC. Well over 50 jumped or fell from the North Tower, none from the South Tower.Someone falling from the WTC. Well over 50 jumped or fell from the North Tower, none from the South Tower. [Source: Associated Press]At some point between the collapse of the two WTC towers, it is claimed that fire chiefs order the firefighters to come down. It has not been reported exactly who issued this order or when. Witnesses claim that scores of firefighters, unaware of the danger, were resting on lower floors in the minutes before the second tower collapsed. “Some firefighters who managed to get out said they had no idea the other building had already fallen, and said that they thought that few of those who perished knew.” At least 121 firefighters in the remaining tower die. The Fire Department blames a faulty radio repeater. However, the Port Authority claims later transcripts of radio communications show the repeaters worked. (Dwyer and Flynn 11/9/2002)

Based on information from the plane’s flight data recorder, the National Transportation Safety Board will later determine that Flight 93’s autopilot is turned off at “about 10:00,” and remains off for the flight’s final minutes. (National Transportation Safety Board 2/13/2002 pdf file) Phil Bradshaw, whose wife is an attendant on Flight 93, will later hear the plane’s cockpit voice recording. Being a pilot himself, he recognizes on it the sound of the alarm that goes off when the autopilot is disconnected. (Ahearn 9/11/2002) CNN’s Kelli Arena will hear the recording during the 2006 Zacarias Moussaoui trial and will report that, shortly after this alarm sounds, “Another alarm goes off.” (CNN 4/12/2006) According to journalist and author Jere Longman, as well as the alarm set off when the autopilot was disconnected, another alarm “would have sounded because the plane was traveling at five hundred seventy-five miles an hour in the final minutes, far exceeding the design limits of four hundred twenty-five miles an hour below twenty thousand feet and two hundred eighty-seven miles an hour below ten thousand feet.” (Longman 2002, pp. 208) So presumably this is the second alarm described by Arena.

The pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) hear a warning over radio that errant aircraft will be shot down, and receive an instruction from the Secret Service to protect the White House. (Spencer 2008, pp. 222-223)
Pilots Learn of FAA Order - The three Langley fighter jets have now reached the Baltimore-Washington area. (Spencer 2008, pp. 222) The pilots hear over their radios that the FAA has ordered all civilian aircraft to land. (Wald and Sack 10/16/2001) (The FAA issued this instruction at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). (US Congress. House. Committee On Transportation And Infrastructure 9/21/2001; 9/11 Commission 7/24/2004, pp. 29) )
Borgstrom Hears Shootdown Warning - The three pilots are all on different radio frequencies, but are able to communicate between themselves on their auxiliary frequency. According to author Lynn Spencer, one of them, Captain Craig Borgstrom, hears a message over the emergency radio frequency that is in response to the FAA’s recent order: “Attention all aircraft! Attention all aircraft! You are ordered to land at the nearest suitable airport. All aircraft must land immediately. Violators will be shot down.” The source of this message is unstated. (Filson 2003, pp. 66; Spencer 2008, pp. 222-223) (Author Leslie Filson will describe the Langley pilots hearing what is apparently a separate but similar message later on, some time after 10:42 a.m. (see 10:05 a.m.-11:05 a.m. September 11, 2001). (Filson 2003, pp. 82) )
Instructed to Protect the White House - Around the time Borgstrom hears this, Major Dean Eckmann, the lead Langley pilot, is on the radio with the FAA’s Washington Center. A Secret Service agent has arrived there and wants to talk to him. (Filson 2003, pp. 68; Spencer 2008, pp. 222-223) Eckmann then receives a garbled message over his radio, which is difficult to make out. (Sack 11/15/2001) The message is, “Protect the house.” Eckmann will later recall, “I took it to mean protect the White House.” (Filson 2003, pp. 68) He notifies the two other pilots—Borgstrom and Major Brad Derrig—of this message. He tells them, “I think I just talked to the Secret Service, but I’m not sure.” (Sack 11/15/2001)
Possible Shootdown Order? - According to Spencer, this message means that “Unknown to NEADS” (NORAD’s Northeast Air Defense Sector), Eckmann has been “given shootdown authority directly from the Secret Service, bypassing the military chain of command.” (Spencer 2008, pp. 223) But Borgstrom and Derrig will later say they “never received explicit orders to fire on incoming planes perceived to be hostile.” (Sack 11/15/2001) Borgstrom radios NEADS weapons director Steve Citino and asks for specific instructions about what to do (see 10:07 a.m. September 11, 2001). (Spencer 2008, pp. 223) According to the 9/11 Commission, NEADS will only learn that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m., and even then it does not pass this order along to the fighter pilots under its command (see 10:31 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 42-43)

A security officer for one of the businesses in Building 7 of the World Trade Center (WTC 7) goes up WTC 7 and subsequently becomes trapped on its seventh floor. (National Institute of Standards and Technology 9/2005, pp. 109-110; National Institute of Standards and Technology 11/2008, pp. 298-299) Although most people were evacuated from the building around the time the South Tower was hit, if not earlier (see (9:03 a.m.) September 11, 2001), after the South Tower collapses at 9:59 a.m. the security officer heads up to a floor in the 40s in WTC 7, reportedly to check that all his personnel have left. (The name of the company he works for is unstated.) He is initially accompanied by a police officer, but at around the 10th floor this officer has difficulty breathing, and so goes back down and exits the building. When the North Tower collapses at 10:28 a.m., WTC 7 shakes and the stairwell goes dark. The security officer, who has reached the 30th floor by this time, heads back down the stairs. When he reaches the 23rd floor, where the headquarters of New York’s Office of Emergency Management (OEM) is located, he opens the door to check for any members of staff that might still be there, but finds the area filled with smoke. (The OEM was evacuated at about 9:30 a.m., if not earlier (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (9:30 a.m.) September 11, 2001).) He then continues down to the seventh floor, where he has to stop because he is unable to see or breathe. He is able to break a window, and calls for help. (National Institute of Standards and Technology 11/2008, pp. 298-299) At around 12:10 to 12:15 p.m., firefighters will enter the building and rescue the security officer, escorting him down the stairs and out of the building. They will also rescue two men who are trapped on the eighth floor (see 12:10 p.m.-12:15 p.m. September 11, 2001). (National Institute of Standards and Technology 6/2004; National Institute of Standards and Technology 9/2005, pp. 110)

Defense Secretary Donald Rumsfeld returns from the Pentagon crash site “by shortly before or after 10:00 a.m.” Then he has “one or more calls in my office, one of which was with the president,” according to his testimony before the 9/11 Commission. (9/11 Commission 3/23/2004) The commission later concludes that Rumsfeld’s call with President Bush has little impact: “No one can recall any content beyond a general request to alert forces.” The possibility of shooting down hijacked planes is not mentioned. (9/11 Commission 6/17/2004) Rumsfeld then goes to the Executive Support Center (ESC) located near his office, arriving there at around 10:15 a.m. In the ESC already are Stephen Cambone, Rumsfeld’s closest aide, Larry Di Rita, Rumsfeld’s personal chief of staff, and Victoria Clarke, the assistant secretary of defense for public affairs. Rumsfeld had instructed Di Rita and Clarke to go to the ESC and wait for him there when they’d come to his office soon after the second WTC tower was hit at 9:03 A.M. (see (Shortly After 9:03 a.m.) September 11, 2001). Presently, Rumsfeld gives them their first confirmation that a plane hit the Pentagon, saying, “I’m quite sure it was a plane and I’m pretty sure it’s a large plane.” According to Clarke, he pulls out a yellow legal pad and writes down three categories, “by which his thinking would be organized the rest of the day: what we needed to do immediately, what would have to be underway quickly, and what the military response would be.” (Clarke 2006, pp. 221-222; Cockburn 2007, pp. 5-6) The Executive Support Center has secure video facilities, and while there, Rumsfeld participates in the White House video teleconference. This is the video conference that counterterrorism “tsar” Richard Clarke claims Rumsfeld is a part of much of the morning (see (9:10 a.m.) September 11, 2001). Then at around 10:30 a.m., he moves on to the National Military Command Center NMCC, located next door to the ESC (see (10:30 a.m.) September 11, 2001). (Scarborough 2/23/2004; 9/11 Commission 6/17/2004; 9/11 Commission 7/24/2004, pp. 43-44) Those in the NMCC are apparently unaware of Rumsfeld’s whereabouts during the half-hour from 10 a.m. to 10:30 a.m.: Brigadier General Montague Winfield later recalls, “For 30 minutes we couldn’t find him. And just as we began to worry, he walked into the door of the [NMCC].” (ABC News 9/11/2002)

Dick Cheney talking to Condoleezza Rice.Dick Cheney talking to Condoleezza Rice. [Source: David Bohrer / White House] (click image to enlarge)According to the 9/11 Commission, Vice President Dick Cheney is told that the Air Force is trying to establish a combat air patrol (CAP) over Washington. Cheney, who is in the Presidential Emergency Operations Center (PEOC) below the White House, then calls President Bush on Air Force One to discuss the rules of engagement for this CAP. Cheney later tells the 9/11 Commission that he’d felt “it did no good to establish the CAP unless the pilots had instructions on whether they were authorized to shoot if the plane would not divert.” He recalls that “the president signed off on that concept.” Bush will recall this phone call and emphasize to the 9/11 Commission that, during it, he had authorized the shootdown of hijacked aircraft. National Security Adviser Condoleezza Rice, who is in the PEOC with Cheney, will tell the Commission she recalls hearing Cheney inform the president: “Sir, the CAPs are up. Sir, they’re going to want to know what to do.” Then she hears Cheney say, “Yes sir.” However, as the Commission will later note, “Among the sources that reflect other important events that morning there is no documentary evidence for this call, although the relevant sources are incomplete” (see (Mid 2004)). (9/11 Commission 7/24/2004, pp. 40-41) Reportedly, some members of the Commission’s staff will not believe this call between Bush and Cheney ever took place. (Klaidman and Hirsh 6/20/2004) Cheney phones Bush at 10:18 (see 10:18 a.m.-10:20 a.m. September 11, 2001). According to the 9/11 Commission, it is in fact during that call that Bush authorizes the military to shoot down threatening aircraft. (9/11 Commission 7/24/2004, pp. 41)

A Maryland State Police helicopter.A Maryland State Police helicopter. [Source: Maryland State Police]Sergeant Ronald Galey, the pilot of a US Park Police helicopter responding to the attack on the Pentagon, asks the Maryland State Police to send medical evacuation (medevac) helicopters to help out at the crash scene, but is told, “No, we can’t respond,” apparently because the airspace has been shut down. (Forror 11/2001; Galey 11/20/2001) Galey is flying one of the two Park Police Aviation Unit helicopters that arrived at the Pentagon within minutes of the attack there (see Shortly After 9:37 a.m. September 11, 2001). His helicopter has been circling overhead while the other Park Police helicopter landed to conduct medical evacuations. They are currently the only helicopters to have arrived on the scene.
Pilot Wants More Helicopters to Assist at the Pentagon - Realizing that his helicopter cannot provide its current command and control function and conduct medical evacuations at the same time, Galey requests assistance from other departments that have helicopters equipped to transport injured patients. The first department he calls is the Maryland State Police. (Galey 11/20/2001; McDonnell 2004, pp. 20-22 pdf file) The Maryland State Police Aviation Command owns 12 helicopters and most of its work involves medical transport, with its helicopters carrying injured patients to hospital. (Maryland State Police 2/16/2003; Desmon 3/7/2006) According to Galey, the unit has “the most resources for aircraft, medevac aircraft, that we knew were manned and ready to go.” However, Galey will later recall, in response to his request, “they came back and said, ‘No, we can’t respond.’”
Maryland Police Think They Cannot Launch Helicopters - When Galey is told that the unit cannot respond, he and the rest of his crew are “very shocked,” and, Galey will say, “[T]hat’s when we were starting to suspect there was something more to it.” According to later accounts, the unit cannot respond because the airspace has been shut down. (Forror 11/2001; Galey 11/20/2001) (The FAA has issued a nationwide “ground stop” that prevents any aircraft from taking off (see (9:26 a.m.) September 11, 2001) and has also ordered that all airborne aircraft must land at the nearest airport (see (9:45 a.m.) September 11, 2001). (US Congress. House. Committee On Transportation And Infrastructure 9/21/2001; 9/11 Commission 7/24/2004, pp. 25, 29) Galey is currently unaware that the airspace has been shut down. However, the Maryland State Police helicopters should be able to respond all the same, because NORAD has told him, “The aircraft that you’re calling in, we’re going to allow to come in” (see (Shortly After 9:55 a.m.) September 11, 2001). According to Galey, the Maryland State Police “just didn’t know [that] if we requested them they could come.”
Other Departments Send Helicopters - Galey then contacts MedStar at the Washington Hospital Center and AirCare at Inova Fairfax Hospital in Virginia. Each of them dispatches helicopters to the Pentagon. Galey will recall that these two departments “hadn’t gotten the word that the airspace was shut down, and since I’m the one who requested the aircraft and informed NORAD, NORAD allowed them to come in.” (Forror 11/2001; Galey 11/20/2001) It is unclear exactly when Galey contacts the different departments. But according to the Arlington County After-Action Report, the helicopter that MedStar launches arrives at the Pentagon at around 10:18 a.m. Inova Fairfax Hospital launches one helicopter at “approximately 10:00 a.m.” and then sends a second helicopter to the Pentagon at around 10:40 a.m. (US Department of Health and Human Services 7/2002, pp. A-45 pdf file)

Counterterrorist Center logo.Counterterrorist Center logo. [Source: CIA]At around 10 a.m., following reports that several aircraft were not responding to communications and could be heading toward Washington, CIA Director George Tenet orders the evacuation of the CIA headquarters building in Langley, Virginia (see (9:50 a.m.-10:00 a.m.) September 11, 2001). However, Cofer Black, the director of the Counterterrorist Center (CTC), is unhappy about this and tells Tenet, “Sir, we’re going to have to exempt CTC from this because we need to have our people working the computers.” The CTC, according to the Los Angeles Times, is “the nerve center for the CIA’s effort to disrupt and deter terrorist groups and their state sponsors.” About 200 employees are currently working in it. Eight of them are in the Global Response Center on the sixth floor of the building, monitoring the latest intelligence on terrorism throughout the world. The rest are in a windowless facility low down in the building. When Tenet points out that the Global Response Center staff will be at risk, Black responds, “They have the key function to play in a crisis like this. This is exactly why we have the Global Response Center.” When Tenet points out, “They could die,” Black replies, “Well, sir, then they’re just going to have to die.” After pausing, Tenet agrees, “You’re absolutely right.” Tenet later says, “Now that we were under attack, the Counterterrorist Center, with its vast data banks and sophisticated communications systems, was more vital than ever. Even as we were discussing going or staying, CTC was sending out a global alert to our stations around the world, ordering them to go to their liaison services and agents to collect every shred of information they could lay their hands on.” (Drogin 10/12/2001; Woodward 2002, pp. 8-9; Tenet 2007, pp. 164-165)

Members of Congress who are assembled at the headquarters of the Capitol Police in Washington, DC receive regular briefings from police officers, but these reveal little more than what is being reported in the news. (Lancaster and Dewar 9/12/2001) After being evacuated from the Capitol building, many members of Congress go to the Capitol Police headquarters, located a block and a half away (see (9:55 a.m. and After) September 11, 2001). (Daschle and D'Orso 2003, pp. 110-112) Throughout the day, several hundred of them go there, though some Congressional leaders are moved to a secure bunker outside Washington around late morning or early afternoon (see (Between Late Morning and Early Afternoon) September 11, 2001). (Balz and Woodward 1/27/2002; CNN 9/11/2002) According to Senate Majority Leader Tom Daschle (D-SD), the police headquarters becomes “Congress’s central command center for the rest of the day.” (Daschle and D'Orso 2003, pp. 112) But, CNN will report, “In a place where power means knowing things, nobody knew very much.” Deputy Chief James Rohan of the Capitol Police later describes, “There was somebody [at the headquarters] had brought out a little four inch black and white TV with just an antenna stick on it, plugged it in, and they were getting all their information from the networks from this tiny little TV.” (CNN 9/11/2002) The Senate and House members at the headquarters receive hourly briefings from Capitol Police officers. But, according to the Washington Post, “lawmakers privately described the sessions as ‘rudimentary,’ offering few details beyond published reports.” (Lancaster and Dewar 9/12/2001) According to Daschle, who is among those moved to the secure bunker outside Washington, members of Congress who remain at the police headquarters spend the day “crammed into several conference rooms and offices, working the telephones and watching the TV monitors for developing news,” though he gives no specific details of what they do. (Daschle and D'Orso 2003, pp. 112) Late in the afternoon, about 50 of them speak by phone with the Congressional leaders at the secure bunker (see (5:00 p.m.) September 11, 2001), and during the evening, many of them will join the leaders on the steps of the Capitol building for a press conference (see 7:24 p.m. September 11, 2001).

Hijackers in the cockpit of Flight 93 react to the passengers who are apparently trying to retake control of the aircraft and one of them appears to ask if they should fly the plane into the ground. (9/11 Commission 8/26/2004, pp. 45-46) Passengers on the flight have apparently been trying to force their way into the cockpit, using a food cart as a shield (see 9:57 a.m.-9:59 a.m. September 11, 2001). (Vulliamy 12/2/2001; Longman 2002, pp. 270-271)
Hijacker Asks if He Should 'Finish It Off' - The cockpit voice recording from the plane will later reveal that, in response to this, a hijacker in the cockpit apparently suggests crashing the plane into the ground. Speaking in Arabic, he asks: “Is that it? Shall we finish it off?” Another hijacker in the cockpit replies: “No. Not yet. When they all come, we finish it off!”
Passengers Try to Get into the Cockpit - Seconds later, a male passenger shouts: “Ah! I’m injured.” A hijacker then exclaims: “Oh Allah! Oh Allah! Oh gracious!” A male passenger apparently instructs those with him to continue trying to force their way into the cockpit. “In the cockpit,” he shouts, adding, “If we don’t, we’ll die!” A hijacker then makes some unusual statements. He says: “Up, down. Up, down, in the cockpit. The cockpit. Up, down.” He adds, “Saeed, up, down!” (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 103-104) “Saeed” is presumably Saeed Alghamdi, one of the alleged hijackers of Flight 93. (9/11 Commission 8/26/2004, pp. 35)
Hijacker Again Suggests Crashing the Plane - The cockpit voice recorder then picks up the sound of a male passenger, in the distance, giving the instruction, “Roll it!” He is possibly talking about rolling the food cart forward, journalist and author Tom McMillan will suggest. This is followed by the sound of glasses and plates breaking. A hijacker then apparently starts praying, saying: “Allah is the greatest! Allah is the greatest!” He then appears to suggest crashing the plane into the ground again. “Is that it? I mean, shall we pull it down?” he asks. “Yes, put it in it and pull it down,” another hijacker replies.
Hijacker Says to Shut Off the Oxygen Supply - One of the hijackers then suggests that they turn off the oxygen supply to the cabin, saying: “Cut off the oxygen! Cut off the oxygen! Cut off the oxygen! Cut off the oxygen!” (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 104) (However, cutting off the oxygen below an altitude of 10,000 feet would have little or no effect on the passengers, aviation officials will comment. (Longman 2002, pp. 271) ) About 20 seconds later, he makes more unusual statements, saying: “Up, down. Up, down. Up, down.”
Passengers Continue Their Assault - Within the next 20 seconds, the cockpit voice recorder picks up the sounds of loud crashes, snaps, loud grunts, and a male passenger shouting, “Ah!” A passenger then issues some commands. “Go! Go!” they say. “Move! Move!” they shout. A male passenger—perhaps the same person—then yells loudly, “Turn it up!” What they mean by this is unclear. (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 104) The passengers will apparently continue to struggle against the hijackers until the plane crashes, at 10:03 a.m. (see 10:02 a.m.-10:03 a.m. September 11, 2001). (9/11 Commission 8/26/2004, pp. 46)

Ray Downey.Ray Downey. [Source: Unknown]When the WTC’s South Tower collapses, Father John Delendick—one of New York Fire Department’s chaplains—runs down a ramp to the garages below the nearby World Financial Center, to escape the dust cloud. He speaks there with Fire Chief Ray Downey, and asks him if the jet fuel from the plane had blown up, causing the collapse. (Delendick 12/6/2001) Downey is in fact a renowned expert on building collapses. Robert Ingram, a battalion chief in the New York Fire Department later refers to him as “the premiere collapse expert in the country.” (US Congress. Senate. Committee on Commerce 10/11/2001 pdf file) 9/11 Commissioner Timothy Roemer calls Downey a “very, very respected expert on building collapse.” (9/11 Commission 5/18/2004) And Fire Chief Mike Antonucci, who is a best friend of Downey’s, says he “was probably the most knowledgeable person on building collapses there was. That was his [hobby], to study building collapses—what affected the engineering of buildings, how they [would] weaken and how he could respond and stay safe.” (Marquez 9/7/2006) In response to Delendick’s question, Downey replies that, “at that point he thought there were bombs up there because [the collapse] was too even.” (Delendick 12/6/2001) Earlier on, Downey told other fire chiefs responding at the WTC that he was worried about “explosive devices” in the Twin Towers “that could hurt the firemen” (see (9:20 a.m.) September 11, 2001). He is killed when the North Tower collapses at 10:28 a.m. (Dwyer and O'Donnell 9/9/2005)

United Airlines temporarily loses communication with three of its aircraft. Andrew Studdert, United Airlines’ chief operating officer, will tell the 9/11 Commission that at around 10:00 a.m., the airline loses contact with Flight 399, Flight 415, and Flight 641. Persistent attempts to communicate with these “missing” aircraft are eventually successful. (9/11 Commission 1/27/2004) At 10:45 a.m., the FAA’s Cleveland Center will report that Flight 641 is on the ground at Detroit Metro Airport in Michigan. (Federal Aviation Administration 9/11/2001)

Robert Natter.Robert Natter. [Source: CBS]Rudy Washington, who is one of Rudolph Giuliani’s deputy mayors, had earlier on called Admiral Robert Natter, the commander of the US Atlantic Fleet at Norfolk Naval Station, Virginia, and requested air cover over New York (see (Between 8:46 a.m. and 9:03 a.m.) September 11, 2001). After the WTC’s South Tower collapses at 9:59, Washington heads to City Hall, where he again communicates with Natter. Natter informs him that the Pentagon has been hit, and says he has now gotten permission from NORAD to send some fighter jets over the city. (Crouch 5/20/2004) However, when exactly these jets are launched and when they arrive over New York is unstated. Patrick Burns, who is currently at the Norfolk Naval Station for his two-week Naval Reserve obligation, later recalls, “Air cover was already up with Navy jets out of Naval Air Station Oceana.” Naval Air Station Oceana, in Virginia Beach, Virginia, is home to F-14 Tomcat and F/A-18 Hornet fighters. But Burns does not state a time for when these fighters are airborne. (Riley 9/22/2001; Richards 10/2001; Burns 4/2007) The 9/11 Commission Report will make no mention of any Naval fighters. (9/11 Commission 7/24/2004)

Abu Laila.Abu Laila. [Source: Democratic Front for the Liberation of Palestine]The Democratic Front for the Liberation of Palestine (DFLP), a radical Palestinian group, denies responsibility for the terrorist attacks in the US after an Arab television station said it admitted responsibility for them. (Wilkinson and Curtius 9/12/2001; Geisler 9/2/2002) At around 9:43 a.m., Abu Dhabi television reported that it had received a call from the DFLP, claiming responsibility for crashing the planes into the World Trade Center (see (9:43 a.m.) September 11, 2001). (BBC 9/12/2001) Now, however, a spokesman for the DFLP denies that the group was behind the attacks. (Geisler 9/2/2002) The spokesman who issues the denial at this time is apparently Qais Abdel Rahim, the leader of the DFLP. Speaking from the West Bank, Rahim says his group condemns the attacks. “We are not responsible for this type of terror attack. We are against it,” he says. (Associated Press 9/11/2001; Liverpool Daily Post 9/12/2001)
Group's Leaders Are Unaware of the Attacks - DFLP officials will subsequently review the group’s worldwide operations to see if the group has any links to the attacks. “I called all the DFLP offices outside Palestine; I made sure they had no connection to the attacks—or even to the media reports,” Abu Laila, a senior figure in the DFLP, will later recall. The group’s leaders will tell him that “they were not even aware of the attacks.”
Official Statement Will Deny Responsibility for the Attacks - The DFLP will issue an official statement later today, denying responsibility for the attacks in the US. (Baboun and Hale 9/11/2011) “The Democratic Front rejects any kind of operation outside of the land of occupied Palestine, away from the immediate battlefield confronting the occupation forces and the armed settlers,” the statement will say. The DFLP will blame the false attribution of responsibility on “the Israeli security intelligence agencies,” which, it will state, “are trying to frame us.” These agencies, according to the statement, “orchestrated the set-up to criminalize our struggle because of our fidelity to this struggle, and our sophisticated way of organizing under the leadership of the working class and the progressive people of Palestine.” (Democratic Front for the Liberation of Palestine 9/11/2001)
Experts Believe that Palestinian Groups Are Not to Blame - Most experts in the US will agree that “no Palestinian faction has the wherewithal to carry out such a coordinated and well-executed series of attacks” as have occurred today, according to the Los Angeles Times. (Wilkinson and Curtius 9/12/2001) One expert, Eli Carmon of the Herzliya Interdisciplinary Center’s counterterrorism department, will say it is unlikely that any Palestinian groups are involved. “They have a lot to lose because America would react very harshly against the Palestinians,” he will say. (Irish Examiner 9/11/2001) “The DFLP does not even confront Israel; how would it confront the US?” Laila will comment. (Baboun and Hale 9/11/2011)

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. (Bronner 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). (Wasilewski 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; Bronner 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.” (Bronner 8/1/2006)

Steve Lanoce.Steve Lanoce. [Source: Gamezebo]A group of police officers tries to enter World Trade Center Building 7 in order to get out of the WTC plaza, but they find the door is locked and the building is on fire. The seven officers are members of New York Police Department’s Emergency Service Unit (ESU). They were about 60 yards north of the South Tower when it collapsed, at 9:59 a.m. (see 9:59 a.m. September 11, 2001). When the dust began to clear, they made their way to the WTC plaza. But as they then tried to get out of the plaza, they found that every corner they ran to was blocked.
Officers Find the Door to WTC 7 Is Locked - The ESU officers now notice the bridge that leads from the plaza to WTC 7, and wonder if they can get out of the plaza by entering WTC 7 and then making their way down to the street below. (Hanley 6/2002 pdf file; Appel 2009, pp. 99-100) WTC 7, a 47-story office building, is located to the north of the Twin Towers. It is linked to the main WTC complex by a glass-enclosed pedestrian bridge at the third-floor level. (Federal Emergency Management Agency 5/1/2002, pp. 5-2; National Institute of Standards and Technology 11/2008, pp. 2) The officers walk across the bridge, but when they reach the door that leads into WTC 7 they find it is locked. “Why anyone would lock a door under these circumstances was anybody’s guess,” author Anthea Appel will later comment.
Officers Find WTC 7 Is on Fire - One officer, Steve Lanoce, decides to try to break the door. He takes out his handgun and fires a shot at the bottom glass pane of the door. The glass, however, turns out to be bullet-proof and cracks but does not break. Furthermore, Lanoce’s shot sets off the burglar alarm in WTC 7. Fortunately, Lanoce’s colleagues are able to kick in the cracked glass and create an opening large enough to crawl through. They find, though, that the building on the other side of the door is on fire and they have to jump back to avoid the flames. (Hanley 6/2002 pdf file; Appel 2009, pp. 99-100)
WTC 7 Suffered Only Minor Damage When the South Tower Collapsed - The cause of the fire in WTC 7 is unclear. The National Institute of Standards and Technology, which will investigate the collapse of WTC 7 that occurs later today (see (5:20 p.m.) September 11, 2001), will state that the building suffered only minor damage when the South Tower collapsed. “A few windows on lower floors of the south face of WTC 7 were broken, and dust and small debris were deposited in the third-floor lobby,” it will describe. However, it will add, “None of the large pieces of debris from [the South Tower] hit WTC 7 because of the large distance between the two buildings and there was no evidence of structural damage to WTC 7.” (National Institute of Standards and Technology 11/2008, pp. 16) The ESU officers then notice a stream of people making their way out of the North Tower. They therefore abandon their plan to get out of the WTC complex and instead go to help evacuate the civilians from the tower. (Hanley 6/2002 pdf file; Appel 2009, pp. 101)

The fire alarm system in World Trade Center Building 7 detects a possible fire somewhere in the building, although the exact location of this possible fire is not signified. The alarm system has been placed on “test condition,” which causes any alarms to be ignored, for a period of eight hours, beginning at 6:47 a.m. this morning (see 6:47 a.m.-2:47 p.m. September 11, 2001). (National Institute of Standards and Technology 6/2004, pp. 28) But less than two minutes after the South Tower collapsed (see 9:59 a.m. September 11, 2001), while it is in this condition, the system registers an alarm. This does not necessarily mean there is a fire in the building, however. “Even though a fire alarm is indicated,” a report by the National Institute of Standards and Technology (NIST) will later comment, “the record might have been the result of dust entering smoke detectors.” The alarm record will show that the fire condition occurs in “AREA 1.” However, NIST will be informed that AREA 1 is not a specific area within WTC 7, but instead refers to the entire building. This means that “a fire detected in any fire alarm zone in the building would have resulted in the same AREA 1 identification,” NIST will state. While the alarm system is in test condition, as is currently the case, records of an alarm are recorded in its history file but alarm signals do not appear on the operator’s display. And NIST will state that none of the interviews conducted by its investigation team, which examines the collapse of WTC 7, “contained any mention of an alarm received at the fire command station” in the building’s third-floor lobby. (National Institute of Standards and Technology 11/2008, pp. 68-70)

When a housekeeper at the Park Inn in Boston, where 9/11 hijackers Wail and Waleed Alshehri stayed before the attacks, attempts to clean their room, a “male of foreign descent” tells her she should not clean it yet and should return in the early afternoon, as someone is still asleep there. The hijackers are thought to have left the hotel and checked in for their flights several hours previously (see (6:20 a.m.-7:48 a.m.) September 11, 2001). The male’s identity is unknown and the housekeeper’s story appears to confuse the FBI, as an entry about it in an FBI timeline drafted after the attacks ends with five question marks. (Federal Bureau of Investigation 10/2001, pp. 292 pdf file)

William Zika.William Zika. [Source: William Zika]Inspector Joseph Morris, a commanding officer with the Port Authority Police Department (PAPD), gives the order to move the PAPD’s mobile command post further away from the World Trade Center and thereby likely prevents those in it being killed or seriously injured when the North Tower collapses. (Keegan and Davis 2006, pp. 100-101) The mobile command post is a vehicle the size of a bus that was dispatched from the PAPD’s headquarters in Jersey City when word reached there about the crash at the North Tower (see 8:46 a.m. September 11, 2001). It arrived near the Twin Towers at around 9:30 a.m. and was parked just north of the intersection of West and Vesey Streets, next to Building 6 of the WTC. (Morris 1/2002; Accardi 3/7/2002 pdf file; Keegan and Davis 2006, pp. 8, 100) After the South Tower collapsed (see 9:59 a.m. September 11, 2001), Port Authority personnel gathered at the vehicle to regroup.
Police Captain Says the North Tower Will Collapse - At some point, Captain Anthony Whitaker, the PAPD commanding officer at the WTC, comes to the mobile command post and warns that the North Tower is in danger of collapsing, like the South Tower did. (9/11 Commission 5/18/2004 pdf file) He is convinced that the North Tower is “about to come down any minute,” he will later recall. (Murphy 2002, pp. 187) He approaches Morris outside the vehicle and urgently tells him that “the area is not safe, because [the North Tower] is coming down.” (9/11 Commission 11/10/2003) Presumably in response to Whitaker’s warning, Morris decides that the vehicle needs to be moved to somewhere safer. “I knew that the mobile command post must be moved north on West Street,” he will state. (9/11 Commission 5/18/2004 pdf file) He gets into the vehicle and gives the order, “Move the command post.”
Instruction Is Given to Move the Command Bus - Those in the vehicle groan in frustration when they hear Morris’s order, since “[p]eople were in motion, the command post was almost operational, [and] no one wanted to disconnect everything and start all over,” according to a book by Lieutenant William Keegan of the PAPD. But Morris ignores their objections, points to a location on a map of the city, and says, “Move it there.” (9/11 Commission 11/10/2003; Keegan and Davis 2006, pp. 100)
Fire Trucks Move to Allow the Vehicle to Drive Away - Sergeant William Zika, who is at the mobile command post with Morris, talks with Police Officer Frank Accardi, the vehicle’s driver, and Police Officer Thomas Kennedy “about moving the bus further north to a safer location.” (Zika 3/9/2002) But before they can start the vehicle, Accardi and Kennedy have to clean its air filter, which became clogged with debris when the South Tower collapsed. (Merrill 2011, pp. 232; Law Officer 8/16/2011) Meanwhile, Whitaker starts yelling at the fire trucks parked nearby to free up space so the vehicle can get away. (Murphy 2002, pp. 187)
Moving the Command Bus Reportedly Saves Lives - Accardi then starts the mobile command post, moves it north, and parks it on West Street, between Murray and Chambers Streets. The North Tower of the WTC will collapse while the vehicle is at this location, at 10:28 a.m. (see 10:28 a.m. September 11, 2001). (Accardi 3/7/2002 pdf file; 9/11 Commission 11/10/2003; 9/11 Commission 5/18/2004 pdf file) The tower will crush Building 6 of the WTC, “covering the exact spot where the command post had stood with tons of debris,” Keegan will write. This will mean that Morris’s order to move the vehicle “prevented the deaths of everyone in the PAPD command post,” according to Keegan. (Keegan and Davis 2006, pp. 100-101)

Clifford Allen.Clifford Allen. [Source: New York Daily News]Officers belonging to New York Police Department’s elite Emergency Service Unit (ESU) who are making their way out of the North Tower of the World Trade Center encounter a man of Middle Eastern appearance who is behaving very suspiciously and subsequently arrest him. (Appel 2009, pp. 125-128) The ESU officers were on the 31st floor of the North Tower when the South Tower collapsed, at 9:59 a.m. (see 9:59 a.m. September 11, 2001). A colleague who was outside at the time of the collapse promptly radioed them to say what had happened and instruct them to get out of the building. (9/11 Commission 5/18/2004; Lambkin 9/9/2011)
Suspicious Man Is Apparently Slipping Back into the Tower - As the officers are making their way down the stairs, one of them, Detective Timothy Morley, overhears transmissions coming over the radios of the firefighters he passes about a “suspicious man” who has been ignoring the Fire Department’s orders and is “talking gibberish on his cell phone.” As they approach the 21st floor, Morley and his colleagues encounter this man. They see him watching firefighters going down the stairs and, once he is sure they have gone, slowly making his way into the stairwell. They find it odd that someone is apparently sneaking back into the building while it is being evacuated.
Man Refuses to Say Who He Is - Morley asks the man what he is doing. The man turns around and the ESU officers see that he is about 40 years old, is well dressed, wearing a suit and tie, and has an olive complexion, dark hair, and dark eyes. They think he looks Middle Eastern. He is holding a leather valise in front of him. Morley asks him, “Do you work here?” but the man just stands still and says nothing. Morley then asks, “Who are you?” and again the man says nothing. Suddenly, the man opens his valise and pulls out a white, fluffy, stuffed toy rabbit and shoves it into Morley’s face. Another officer, David Norman, knocks the toy rabbit out of the man’s hand and onto the floor.
Officers Think the Man's Phone May Be a Detonator Device - A few firefighters who are coming down the stairs see the man and ask the ESU officers: “What’d we got? A terrorist?” In response, the man says, menacingly: “You want to know who I am? Let me show you.” He then reaches for a cell phone that is hooked to his belt. Seeing the man’s fingers just an inch from the phone’s keypad, Morley shouts out, “You’re not pressin’ any buttons!” Concerned that the cell phone might be a detonator device, Morley, Norman, and another ESU officer, Clifford Allen, snatch it off the man and toss it onto the floor.
Senior Officer Wants the Man to Be Taken out of the Tower - By this time, more people have come down the stairs and are watching the commotion. Among them are two civilians who work on the 65th floor. Someone asks them if they recognize the suspicious man. They have a good look at him and say, “He’s not from that floor,” referring to the 21st floor. Deciding now that the man doesn’t belong in the building, ESU Lieutenant Venton Hollifield orders: “Get this guy outta here. We’ll find out what he is and who he is later.” A Port Authority Police Department sergeant who is on the stairs starts gathering up the man’s belongings, but when he goes to pick up the toy rabbit, Morley orders him to leave it where it is.
Man Goes into a Rage and Is Then Arrested - The ESU officers then start escorting the man down the stairs. But a couple of flights down, he goes into a rage and tries to get past them to run back upstairs. He starts swearing while flailing his arms, and punching and kicking at the officers. The officers are easily able to restrain him, but at this point Hollifield instructs Morley to arrest him. Morley does so and handcuffs the man behind his back. The man then quietens down and everyone is able to continue down the stairs. But occasionally the man makes an outrageous statement. For example, he says, “I was a soldier in my country” and when he is asked what his country is, he replies, “The Ukraine,” even though he doesn’t look Ukrainian.
Man Laughs When He Sees the Destruction outside the Tower - When the ESU officers reach the plaza level, they see the devastation caused by the collapse of the South Tower through the windows. But while everyone else is shocked at what they see, the suspicious man giggles and says: “Look at the fire. Nice, nice fire.” (Appel 2009, pp. 125-129) Morley and Hollifield will escort the man away from their colleagues and eventually pass him on to the FBI. However, a man in a dark suit—apparently some kind of government agent—will subsequently instruct Morley to keep quiet about the strange man he’d arrested in the North Tower (see After 10:30 a.m. September 11, 2001). (Appel 2009, pp. 131, 173-175) Curiously, considering that the suspicious man threatened the ESU officers with a toy stuffed rabbit, a week later, the New York State Police will be warned that terrorists might try to get bombs onto commercial planes by hiding them inside stuffed toys. But the man’s toy rabbit will never be recovered from the rubble of the North Tower and therefore is not examined to see if it contains explosives. (Appel 2009, pp. 340)

Potential pilots Don Greene and Andrew Garcia.
Potential pilots Don Greene and Andrew Garcia. [Source: Family photos]During this time, there apparently are no calls from Flight 93. Several cell phones that are left on record only silence. For instance, although Todd Beamer does not hang up, nothing more is heard after he puts down the phone, suggesting things are quiet in the back of the plane. (Longman 2002, pp. 218) The only exception is Richard Makely, who listens to Jeremy Glick’s open phone line after Glick goes to attack the hijackers. A reporter summarizes Makely explaining that, “The silence last[s] two minutes, then there [is] screaming. More silence, followed by more screams. Finally, there [is] a mechanical sound, followed by nothing.” (van Derbeken 9/17/2001) The second silence lasts between 60 and 90 seconds. (Longman 2002, pp. 219) Near the end of the cockpit voice recording, loud wind sounds can be heard. (Longman 2002, pp. 270-271; Hirschkorn and Mattingly 4/19/2002) “Sources claim the last thing heard on the cockpit voice recorder is the sound of wind—suggesting the plane had been holed.” (Wallace 9/12/2002) There was at least one passenger, Don Greene, who was a professional pilot. Another passenger, Andrew Garcia, was a former flight controller. (Breslau 9/22/2001; Pittsburgh Post-Gazette 10/28/2001; Harnden 7/31/2002)

Some time after the first WTC tower collapse, counterterrorism “tsar” Richard Clarke orders all landmark buildings and all federal buildings in the US evacuated. He also orders all harbors and borders closed. (Clarke 2004, pp. 14-15) The Sears Tower in Chicago begins evacuation around 10:02 a.m. Other prominent buildings are slower to evacuate. (Ottawa Citizen 9/11/2001)

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. (Sallah and Mahr 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. (McKenna 12/1999; Sallah and Mahr 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; Bronner 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. (McKenna 12/1999; Sallah and Mahr 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). (Sallah and Mahr 12/9/2001; WTOL 9/11/2006)

Bill Wright.Bill Wright. [Source: WTAE-TV]Bill Wright is piloting a small plane when an air traffic controller asks him to look around outside his window, according to his later claims. Wright sees Flight 93 three miles away—close enough that he can see the United Airlines colors. Air traffic control asks him the plane’s altitude, and then commands him to get away from the plane and land immediately. Wright sees the plane rock back and forth three or four times before he flies from the area. He will later say, “That’s one of the first things that went through my mind when they told us to get as far away from it as fast as we could—that either they were expecting it to blow up or they were going to shoot it down, but that’s pure speculation.” (Pittsburgh Channel 9/19/2001) According to the 9/11 Commission, the FAA Command Center tells FAA headquarters that a nearby plane has seen Flight 93 “waving his wings.” The Commission will say, “The aircraft had witnessed the radical gyrations in what we believe was the hijackers’ effort to defeat the passenger assault.” (9/11 Commission 6/17/2004) This presumably is a reference to Wright.

Secret Service emergency response team officers patrolling the South Lawn of the White House.Secret Service emergency response team officers patrolling the South Lawn of the White House. [Source: Associated Press]Laura Bush, the president’s wife, is escorted out of the Russell Senate Office Building in Washington, DC, by members of the Secret Service with their guns drawn, to be driven away to a secure location. (National Journal 8/31/2002; Bush 2010, pp. 200) People began evacuating from the Russell Senate Office Building and the nearby Capitol building at 9:48 a.m., apparently due to concerns that a plane was heading toward Capitol Hill (see 9:48 a.m. September 11, 2001). (Associated Press 9/11/2001; Associated Press 8/21/2002; CNN 9/11/2006) While Bush and her staff were waiting for the Secret Service emergency response team to arrive and take them away from the Russell Office Building, they stayed in the office of Senator Judd Gregg (R-NH) (see (9:50 a.m.-10:00 a.m.) September 11, 2001).
Emergency Response Team Arrives with Guns Drawn - Secret Service agents collect the first lady from Gregg’s office at “[s]ometime after 10:00 a.m.,” Bush will later recall. (Bush 2010, pp. 200) Bush usually travels with four Secret Service agents. (Kessler 2006, pp. 136; Kessler 2009, pp. 181) But her usual agents are now joined by “an additional Secret Service detail and an emergency response team, dressed in black tactical clothing like a SWAT force and moving with guns drawn.” As Bush is being hurried through the hallways, past panicked staffers leaving their offices, members of the emergency response team escorting her shout, “Get back!” and cover her every move with their guns. (Bush 2010, pp. 200)
First Lady Escorted to Her Limousine - Noelia Rodriguez, the first lady’s press secretary, will recall that she and several other members of Bush’s staff reach Bush’s limousine before the first lady does. While they are waiting there, they chat excitedly, asking each other: “What could this be? Where are we going? What’s next?” But the driver instructs them to be quiet, saying, “Ladies, this is a time to pay attention.” “Just then,” Rodriguez will say, “what seemed like two dozen of these ninja guys surrounded the car—Secret Service agents all dressed in black. Mrs. Bush then got in the car.” (National Journal 8/31/2002) Bush will describe, “We reached the underground entrance; the doors on the motorcade slammed shut, and we sped off.” (Bush 2010, pp. 200)
Motorcade Delayed before Leaving Capitol Hill - However, Bush and those accompanying her reportedly face a delay as they are about to drive off. Ashleigh Adams, the first lady’s deputy press secretary, will describe, “At one point, we were all going to leave, and then Mrs. Bush got out of the motorcade and they [presumably members of the Secret Service] told us to stay in the staff van.” At this point, Adams will say, “Everyone was distraught” and they “didn’t know what was going on.” She will add: “We knew something was going on in DC, because we could see people running around. A lot of us were under the impression that there were car bombs going off throughout the city.” Bush and those accompanying her leave Capitol Hill at 10:10 a.m., according to Rodriguez. (National Journal 8/31/2002) Bush’s Secret Service agents say they are going to take everyone to a secure location. This turns out to be the Secret Service headquarters in Washington (see (10:10 a.m.-10:55 a.m.) September 11, 2001). (Kessler 2006, pp. 136)

David Addington.David Addington. [Source: David Bohrer / White House]According to an in-depth examination by the Washington Post, within hours of the 9/11 attacks, Vice President Dick Cheney begins working to secure additional powers for the White House. Cheney had plans in place to begin acquiring these powers for the executive branch before the attacks, but had not begun to execute them.
Gathering the Team - David Addington, Cheney’s general counsel and legal adviser, had been walking home after having to leave the now-evacuated Eisenhower Executive Office Building. He receives a message from the White House telling him to turn around, because the vice president needs him. After Addington joins Cheney in the Presidential Emergency Operations Center (PEOC) below the East Wing of the White House, the pair reportedly begin “contemplating the founding question of the legal revolution to come: What extraordinary powers will the president need for his response?” Later in the day, Addington connects by secure video with Timothy Flanigan, the deputy White House counsel, who is in the White House Situation Room. John Yoo, the deputy chief of the Office of Legal Counsel, is also patched in from the Justice Department’s command center. White House counsel Alberto Gonzales joins them later. This forms the core legal team that Cheney will oversee after the terrorist attacks. Associate White House counsel Bradford Berenson will later recall: “Addington, Flanigan and Gonzales were really a triumvirate. [Yoo] was a supporting player.” Addington dominates the group. Gonzales is there primarily because of his relationship with President Bush. He is not, Yoo will later recall, “a law-of-war expert and [doesn’t] have very developed views.” Along with these allies, Cheney will provide what the Washington Post calls “the rationale and political muscle to drive far-reaching legal changes through the White House, the Justice Department, and the Pentagon,” which will free the president to fight the war on terror, “as he saw fit.”
Drafting the AUMF - The team begins drafting the document that will become the Authorization to Use Military Force (AUMF—see October 10, 2002) passed by Congress for the assault on Afghanistan. In the words of the group, the president is authorized “to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States.”
Extraordinarily Broad Language - The language is extraordinarily broad; Yoo will later explain that they chose such sweeping language because “this war was so different, you can’t predict what might come up.” The AUMF draft is the first of numerous attempts to secure broad powers for the presidency, most justified by the 9/11 attacks. The Washington Post will later report, “In fact, the triumvirate knew very well what would come next: the interception—without a warrant—of communications to and from the United States” (see September 25, 2001). (CNN 9/11/2001; CNN 9/12/2001; Unger 2007, pp. 220-221; Gellman and Becker 6/24/2007)

Rich Gibaldi.Rich Gibaldi. [Source: Rich Gibaldi]Colonel Ed Boyle, director of intelligence for the Air Combat Command (ACC), and Colonel Rich Gibaldi, another senior Air Force intelligence officer, are ordered to return to Langley Air Force Base in Virginia to get the Predator drone, a remotely controlled, unmanned plane, ready to deploy over Afghanistan. Boyle spent part of the summer organizing an expanded “expeditionary intelligence squadron” to fly Predators over Afghanistan for the CIA, beginning on September 25, but he has recently had time for some other business. He and Gibaldi flew to Davis-Monthan Air Force Base in Arizona, where, yesterday, they attended some meetings.
Officers Learned of the Attacks While Driving to an Army Base - The two officers learned of the attacks on the World Trade Center this morning as they were driving from there to Fort Huachuca, an Army base in southern Arizona, where they were going to attend a change of command ceremony. They heard of the crashes on the car radio. After hearing about the second one, Boyle told his colleague, “We’ve got a problem.” The officers arrived at Fort Huachuca within half an hour.
Officer Was Told to Return to Langley Air Force Base - While they were at the gate, Boyle’s cell phone rang. On the other end of the line was Lieutenant General Donald Cook, acting commander of the ACC, calling from ACC headquarters at Langley Air Force Base. After Boyle said where he and Gibaldi were, Cook told him to get back to Langley Air Force Base as soon as possible and ordered him to call back from a secure phone. Boyle was unable to use a secure phone at Fort Huachuca. But with the ceremony there canceled in response to the terrorist attacks, he and Gibaldi apparently left the base promptly to head back to Davis-Monthan Air Force Base.
Commander Asks about Getting Drones Airborne - Now, as they are driving to Davis-Monthan, Boyle calls Cook and explains that it will be some time before he can call from a secure phone. Cook then tells him he will need to get Predator drones ready for use as soon as possible. “You need to get your butt back here,” he says. He adds that General John Jumper, the Air Force chief of staff, “wants to know when you can be operational and flying.”
Officer Is Told the White House Wants Drones over Afghanistan - After Boyle and Gibaldi arrive back at Davis-Monthan Air Force Base, Boyle finds a secure phone and calls Cook. (Whittle 2014, pp. 232-233, 236) Cook received a call earlier this morning in which he was told the White House wanted to know when Predators could be deployed (see (Before 9:45 a.m.) September 11, 2001). (Whittle 3/2015) He now tells Boyle about this call, saying the White House wants to know how soon the Air Force can get three Predators, armed with Hellfire missiles, over Afghanistan. Boyle and Gibaldi will subsequently have to drive the long distance from Davis-Monthan Air Force Base to Langley Air Force Base, and will arrive at Langley early on the morning of September 14. (Whittle 2014, pp. 236, 238-239) The first Predator mission over Afghanistan will take place on September 18 and on October 7, the first day of the war in Afghanistan, the first armed Predator mission will be flown (see September 18-October 7, 2001 and October 7, 2001). (9/11 Commission 3/24/2004 pdf file; Grimes 2014, pp. 335)

An aircraft that is in Sarasota, Florida, in support of President Bush’s visit there takes off with people and equipment on board shortly after Air Force One leaves Sarasota, and will eventually make its way back to Washington, DC. (Bates 10/2002) Air Force One took off from Sarasota-Bradenton International Airport with Bush on board at around 9:54 a.m. (see 9:54 a.m. September 11, 2001). (Balz and Woodward 1/27/2002; 9/11 Commission 7/24/2004, pp. 39) Members of the president’s entourage who have stayed behind in Sarasota subsequently load the second aircraft with vehicles and other items. The aircraft would normally be used just to transport people back to Washington. But Lieutenant Colonel Thomas Herman, a senior presidential communications officer, will later recall that all of the presidential limousines “and a bunch of equipment we had which I can’t really discuss” are loaded onto it. The aircraft then takes off from the Sarasota airport “not too long after the president got airborne.” Those on the aircraft, as well as Herman, include members of the Secret Service and Major Paul Montanus, one of the president’s military aides. Herman will not say where the aircraft goes, or why, after it leaves Sarasota. “Obviously we were in the air for a reason, for any contingency,” he will say. “Basically we could have gone to any city or county or location in the United States, and landed and supported the president at that location.” Herman will add that the flight “became a special mission.” The aircraft will land at Andrews Air Force Base, just outside Washington, “about 15 minutes after the president,” according to Herman. (Bates 10/2002) This would mean it lands at around 6:45 p.m. (Sammon 2002, pp. 127; Rove 2010, pp. 263)

Pilots from the 180th Fighter Wing who are called to service on 9/11.Pilots from the 180th Fighter Wing who are called to service on 9/11. [Source: WTOL]Two fighter pilots with a Toledo, Ohio, military unit that answer a call from NORAD’s Northeast Air Defense Sector (NEADS), requesting assistance in response to the morning’s attacks, respond as if they think the call is a joke. (Spencer 2008, pp. 178-179) The pilots belong to the 180th Fighter Wing of the Ohio Air National Guard, which is based at Toledo Express Airport. (GlobalSecurity (.org) 1/1/2002; WTOL 9/11/2006)
Pilot Puzzled by Call - When a weapons technician at NEADS contacts the Toledo unit, his call is answered by F-16 pilot Ed Rinke. The weapons technician says, “We need you to scramble two airplanes right now.” However, according to author Lynn Spencer, “to Rinke, the order makes no sense.” The Toledo unit “is not an alert squadron and does not report to NEADS.” Rinke is only a part-time pilot, and thinks someone more suitable should be taking the call. He shouts down the hall: “Hey, we’ve got a phone call at the duty desk. Some guy wants us to launch alert fighters!” Pilot Scott Reed responds: “What? We don’t do that!” Pushing the phone toward Reed, Rinke says: “You take it! It’s somebody on drugs.”
Second Pilot Tells NEADS It Is Calling 'the Wrong People' - After Reed takes the phone, the weapons technician repeats his request, saying, “Major Reed, we need you to scramble two airplanes.” Yet Reed sounds as baffled as Rinke had been. He answers: “You’re calling Toledo, Ohio. Do you not understand who you’re calling here? Who are you trying to call, because you are obviously calling the wrong people. This is Toledo. We don’t have any alert birds. This is Toledo. Do you understand that?”
Commander Takes Call, Orders Launch - Fortunately, the two pilots’ wing commander then takes over the call and responds to it more appropriately. Within minutes, according to Spencer, he will instruct Reed and Rinke to take off in two F-16s. Rinke reportedly thinks to himself, “Things must be really bad if NEADS is launching Toledo on an active air scramble!” (Spencer 2008, pp. 178-179) The Toledo Blade will later comment, “Toledo’s response on Sept. 11 is believed to be the first time the unit has answered a call from the North American Aerospace Defense Command.” Two 180th Fighter Wing jets will take off from the Toledo unit at 10:17 a.m., but accounts will conflict over who the pilots are (see 10:17 a.m. September 11, 2001).

John McWethy.John McWethy. [Source: Steve Fenn / ABC]ABC News correspondent John McWethy was at the Pentagon at the time it was hit. (Peyser 9/24/2001) At some later time, an army general he knows offers to take him in closer to the crash site. McWethy recalls: “I got in very close, got a look early on at the bad stuff. I could not, however, see any plane wreckage—it was well inside and had been, basically, vaporized.” (Gilbert et al. 2002, pp. 187) The following day, Arlington County Fire Chief Ed Plaugher will similarly tell reporters: “[T]here are some small pieces of aircraft visible from the interior during this firefighting operation… but not large sections. In other words, there’s no fuselage sections and that sort of thing.” (US Department of Defense 9/12/2001) According to the Defense Department’s book about the Pentagon attack: “The front part of the relatively weak fuselage [of Flight 77] disintegrated, but the mid-section and tail-end continued moving for another fraction of a second.… The chain of destruction resulted in parts of the plane ending up inside the Pentagon in reverse of the order they had entered it, with the tail-end of the airliner penetrating the greatest distance into the building.” (Goldberg et al. 2007, pp. 17) Navy Lt. Kevin Shaeffer reportedly sees a “chunk of the 757’s nose cone and front landing gear” in the service road between the Pentagon’s B and C Rings. (Swift 9/9/2002) Other witnesses say they see a large airplane tire. (Office of Medical History 9/2004, pp. 117-118; Goldberg et al. 2007, pp. 54) Army Staff Sgt. Mark Williams, whose search and rescue team enters the Pentagon less than four hours after the attack, recalls seeing “the scorched bodies of several airline passengers… still strapped into their seats” inside the building.

Air traffic controllers at the Cleveland Terminal Radar Approach Control (TRACON) remain suspicious of Delta Air Lines Flight 1989 as it is coming in to land at Cleveland Hopkins Airport, due to the pilot’s failure to use an important standard term in his communications with them. (Federal Aviation Administration 9/16/2001) A TRACON is an FAA facility that guides aircraft approaching or departing an airport. Flights coming in to land will subsequently be passed on to the airport’s air traffic control tower once they are within five miles of the airport and below 2,500 feet. (Federal Aviation Administration 3/24/2006) The Cleveland TRACON is in contact with Delta 1989 as it descends from 9,000 feet down to 3,000 feet. (Federal Aviation Administration 9/16/2001) Delta 1989, a Boeing 767 out of Boston, is mistakenly suspected of being hijacked (see 9:39 a.m. September 11, 2001 and (Shortly After 9:44 a.m.) September 11, 2001) and has been instructed to land as soon as possible in Cleveland (see (9:42 a.m.) September 11, 2001). (Adams, Levin, and Morrison 8/13/2002; 9/11 Commission 7/24/2004, pp. 27-28; Spencer 2008, pp. 167-168; Levin 9/11/2008)
Pilot Does Not Use Term 'Heavy' - A detailed timeline provided by the Cleveland Airport control tower shortly after 9/11 will describe, “One anomaly that perpetuated concern by approach controllers in the face of constant information that there was nothing going on with [Delta 1989] was that the pilot never used the HEAVY designator in his communications.” (Federal Aviation Administration 9/16/2001) The term “heavy” alerts controllers to provide extra spacing behind very large aircraft, which are above a certain weight, because these aircraft generate significant wake turbulence. (Getline 6/1/2005; Getline 5/22/2006)
Controllers Skeptical of Delta 1989's Security - While the TRACON controllers use the “heavy” designator, “the pilot [of Delta 1989] did not respond with it.” The control tower’s timeline will state that, while this detail “may seem minor,” it “should not be overlooked. The use of HEAVY in the terminal environment is of the highest importance. Increased separation standards are required, and misapplication of separation standards can be disastrous. For pilots, not referring to a heavy aircraft as HEAVY is tantamount to calling a doctor ‘Mister.’” As a result, “This omission, along with all of the other information flying around, kept everyone alert and skeptical of the security of the flight.” (Federal Aviation Administration 9/16/2001)

Dorothy Garcia.Dorothy Garcia. [Source: Darryl Bush / San Francisco Chronicle]Andrew Garcia, a passenger on Flight 93, makes a phone call to his wife, Dorothy Garcia, but is quickly cut off and does not call again. (Longman 2002, pp. 190-191; Discovery Channel 2005) Garcia, a 62-year-old businessman from Portola Valley in the San Francisco Bay Area, calls his wife on his cell phone. He is only able to get out one word, her name “Dorothy.” (Los Angeles Times 9/14/2001; Seshadri 9/26/2001; Squatriglia 12/27/2001) According to Garcia’s son, the line then “got staticky and faded out.” (Goodyear et al. 9/14/2001)

Richard Dearlove.Richard Dearlove. [Source: Daily Express]CIA Director George Tenet later recalls that, at some unspecified time during this day, a commercial passenger jet on its way to Britain behaves suspiciously, raising fears that al-Qaeda might have launched a two-continent attack. Aircraft are equipped with a device called a transponder, which transmits information to controllers on the ground, such as the plane’s flight number, altitude and speed. But this plane is emitting all kinds of “squawks,” with its transponder going off and on. Tenet calls Richard Dearlove, his counterpart at the British Secret Intelligence Service (MI6), to inform him of what is going on. Eventually, according to Tenet, the problem is resolved, and it turns out to have been caused simply by the transponder being faulty. (Lane, Phillips, and Snyder 9/17/2001; Tenet 2007, pp. 166)

General Henry Shelton, the chairman of the Joint Chiefs of Staff, talks over the phone with General Richard Myers, the vice chairman of the Joint Chiefs of Staff, who is at the Pentagon, and is given information about the Pentagon attack and the military’s response to the terrorist attacks. Shelton took off at 7:15 a.m. to fly to Europe for a NATO conference (see 7:15 a.m. September 11, 2001). He learned of the attacks in New York while his plane was over the Atlantic Ocean, and has just been told of a “big explosion at the Pentagon” (see (8:50 a.m.-10:00 a.m.) September 11, 2001).
First Report Is of a Hand Grenade Going Off at Pentagon - Shelton heads to the communications console just behind the plane’s cockpit. From there, he talks over a secure, encrypted phone line with Myers, who is in the National Military Command Center (NMCC) at the Pentagon. Myers updates Shelton on what is known about the explosion at the Pentagon. He says the first report is that a hand grenade went off in the Pentagon parking lot.
Myers Updates Shelton on Military Response to Attacks - Myers then gives Shelton a complete status report. He says: “We’ve transitioned the SIEC [significant event conference] into an air threat conference call, which is in progress as we speak (see 9:29 a.m.-9:34 a.m. September 11, 2001 and 9:37 a.m.-9:39 a.m. September 11, 2001). FAA has requested that NORAD take over control of US airspace. Fighters have scrambled to escort Air Force One (see (After 9:56 a.m.) September 11, 2001) and we’re sending AWACS up to provide further monitoring (see Before 9:55 a.m. September 11, 2001). We’ve escalated to Threatcon Delta and are about to launch the NAOC [National Airborne Operations Center plane]. Bases around the world are locked tight, [Deputy Secretary of Defense Paul] Wolfowitz has been relocated to Site R (see (11:00 a.m.) September 11, 2001), plus, [Deputy National Security Adviser Stephen] Hadley has requested we implement full ‘Continuity of Government measures’ (see 9:59 a.m. September 11, 2001), and we are proceeding along those lines.”
Myers Says Plane Hit the Pentagon - Myers is then interrupted by some commotion in the background. When he returns to the line, he tells Shelton, “Okay, we just got the word: the prior report was incorrect; it was not a hand grenade that exploded, it was another commercial airline that struck the Pentagon.” He then continues with his status report, saying, “[P]er the president, we’ve gone weapons free in the event of a hijacked aircraft or one that threatens the White House.” (Giesemann 2008, pp. 20, 22-24; Shelton, Levinson, and McConnell 2010, pp. 430-433)
Shelton Wants to Return to Washington - Myers will tell the 9/11 Commission that after he arrives at the NMCC—presumably referring to the time of this phone call—he “recommended General Shelton return to Washington, DC.” (9/11 Commission 6/17/2004 pdf file) But Shelton will recall that he tells Myers, “I need you to call Ed Eberhart [General Ralph Eberhart, the commander of NORAD] at NORAD and let him know that we’re coming back [to Washington] on Speckled Trout [the nickname of the plane he is on], and tell him that I would consider it a personal favor if he would see to it that the chairman and his crew are not shot down on their way back to Andrews.” Myers confirms, “Will do.” According to Shelton, his plane is called back 10 minutes later “with confirmation that we had been officially cleared to fly through the shutdown airspace.” (Shelton, Levinson, and McConnell 2010, pp. 433) But according to Captain Rob Pedersen, the flight navigator on Shelton’s plane, it is several hours before the plane is cleared to enter the US airspace (see (After 9:45 a.m.) September 11, 2001). (McCullough 9/2011 pdf file) The plane will therefore only land at Andrews Air Force Base, near Washington, at 4:40 p.m. (see 4:40 p.m. September 11, 2001) and Shelton will only arrive at the NMCC an hour after that (see 5:40 p.m. September 11, 2001). (Federal Aviation Administration 9/11/2001 pdf file; Myers 2009, pp. 159) The exact time of the call between Shelton and Myers is unclear, though it would be at some time after about 10:00 a.m., when Myers arrives at the NMCC (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001).

The headquarters of the American Enterprise Institute in Washington, DC.The headquarters of the American Enterprise Institute in Washington, DC. [Source: Vornado / Charles E. Smith]David Frum, a speechwriter for President Bush, spends an hour on the phone with Richard Perle, the chairman of the Defense Policy Board, and Perle tells him the president needs to say he will hold not just terrorists but also the nations that harbor them responsible for the morning’s attacks. (Tanenhaus 7/2003) Frum is currently at the headquarters of the American Enterprise Institute (AEI) think tank in Washington, DC, while Perle is at his vacation home in the south of France. (Packer 2005, pp. 40) Frum went to the AEI headquarters after he was evacuated from the Eisenhower Executive Office Building, next to the White House (see (9:45 a.m.) September 11, 2001). On the way, he was joined by John McConnell, Vice President Dick Cheney’s chief speechwriter. After they arrived at the AEI headquarters, sometime after 10:00 a.m., Chris DeMuth, AEI’s president, offered the two men the use of offices, telephones, and Internet connections. (Frum 2003, pp. 115-117)
Frum and Perle Discuss Attacks and How the US Should Respond - Frum therefore talks over the phone with Perle for about an hour. (Tanenhaus 7/2003) “We had a very long conversation,” Frum will later recall, “and touched on a lot of things: where [the attacks] had come from and the mistakes of the past, things to be avoided.” The thing that emerges “most clearly” from the conversation, according to Frum, is how important it is for the president to “make it clear at the start: this was not going to be more law enforcement—they were not going to be indicting these terrorists—that this was to be understood as war.” (Frum 7/7/2004) Therefore, Perle says to Frum, “Whatever else the president says, he must make clear that he’s holding responsible not just terrorists but whoever harbors those terrorists.” (Tanenhaus 7/2003)
Speechwriters Leave AEI to Join Other White House Staffers - Frum and McConnell will subsequently leave the AEI headquarters and head to the DaimlerChrysler building in Washington, where dozens of White House employees go to continue their work. There, the two men will work on a statement for Bush to deliver when he returns to the capital. (Frum 2003, pp. 117-118, 120; McBride 9/9/2011) After he arrives back at the White House, Bush will give a speech to the nation from the Oval Office (see 8:30 p.m. September 11, 2001). (CNN 9/12/2001; Balz and Woodward 1/27/2002) The speech Frum and McConnell work on, however, will have been discarded, with the president using something different. (Frum 7/7/2004) But Bush will say in his speech that America “will make no distinction between the terrorists who committed these acts and those who harbor them.” (US President 9/17/2001) Referring to the speech, journalist and author George Packer will comment: “Bush followed Perle’s advice to the word and then expanded on it: The rest of the world was either with America or with the terrorists.” (Packer 2005, pp. 40)

Rudy Washington.Rudy Washington. [Source: Congress of Racial Equality]After being caught in the dust plume when the WTC’s South Tower collapses at 9:59, Rudy Washington, who is one of Rudolph Giuliani’s deputy mayors, heads to City Hall, where he coordinates the city’s emergency response to the attacks. He is in contact with New York Governor George Pataki, high-ranking New York Police Department officers, and Navy Admiral Robert Natter, the commander of the US Atlantic Fleet (see (Shortly After 9:59 a.m.) September 11, 2001). He orders the closing of bridges. (Though, according to some accounts, the New York Port Authority ordered all bridges to be closed earlier on, at 9:21 (see 9:21 a.m. September 11, 2001).) As New York Daily News columnist Stanley Crouch later describes, Washington also finds “heavy machinery to get downtown for the cleanup and got the Navy to guard against a seaborne attack. He evacuated City Hall, which shook like crazy when the second tower fell. He gathered people who could give medical help, gave the order to find lights that could be used at Ground Zero and worked out new phone communications, since power was being lost. Accompanied by city engineers, he went into the streets around the fallen towers, testing the ground to make sure it would hold when the heavy equipment came in.” Washington’s efforts at developing an emergency strategy are reportedly aided by what he learned at an anti-terrorist training session chaired by counterterrorism “tsar” Richard Clarke and held at the WTC, in preparation for the millennium celebration (see (Late 1999)). Stanley Crouch later credits Rudy Washington with having “ran New York for the first few hours after the attack during a period when Giuliani was thought to have been killed inside the first building that went down.” (Crouch 5/20/2004) During the initial hours following the attacks, between around 9:50 a.m. and midday, Mayor Giuliani is moving around between a series of temporary command posts (see (9:50 a.m.-10:10 a.m.) September 11, 2001 and (After 10:28 a.m.-12:00 pm.) September 11, 2001).

Throughout the day of 9/11 and after, members of the public in New York City experience significant communications problems, particularly with cell phones. “In the aftermath [of the attacks], and for several days afterwards, cellular phone services were either not working or were severely overloaded.” (SatNews 10/19/2001) As Time magazine reports, “Lines formed, at least 20 people long, at all pay phones, because cell phones were not working.” (Gibbs 9/14/2001) (Reportedly, though, the 911 system is not disrupted.) Later accounts will suggest that an increased volume of phone calls being made in response to the attacks may have overloaded networks. Within minutes of the first attack, according to the New York Times, there were “tens of millions of [phone] calls—many from worried relatives and friends—that threatened to clog the system.” (Guernsey 9/20/2001) The call volume of Verizon Communications, which has its main regional switching station across the street from the World Trade Center, reaches twice its normal daily rate of 115 million calls in New York City. “And although it remained operational, the wireless network experienced massive congestion that prevented most calls from getting through. During the peak of the chaos, Verizon experienced nearly 100 percent more traffic than normal on its nationwide wireless network.” (Verton 2003, pp. 148) Some of the communications problems in the New York area are later attributed to physical damage to the infrastructure. A report by the Mineta Transportation Institute will summarize, “The collapse of the World Trade Center towers knocked out Verizon’s switching center in Lower Manhattan and severely damaged the infrastructure for cellular telephones. Telephone communications for NYPD Command and Control was also destroyed in the attack. As a consequence, cell phone service was subsequently overloaded. NYC Transit lost a key portion of its fiber-optic network in one tunnel.” (Jenkins and Edwards-Winslow 9/2003, pp. 33 pdf file) Similar communication problems are also experienced around Washington, DC, and some top government officials are affected (see (After 8:55 a.m.) September 11, 2001). According to one government official, the nation was “deaf, dumb, and blind” for much of the day. (Verton 2003, pp. 151)

Shortly after arriving at Washington’s Dulles Airport, from which Flight 77 took off, the FBI confiscates a security tape from a checkpoint through which the hijackers passed before boarding the plane. Airport security manager Ed Nelson will later say: “They pulled the tape right away.… They brought me to look at it. They went right to the first hijacker on the tape and identified him. They knew who the hijackers were out of hundreds of people going through the checkpoints. They would go ‘roll and stop it’ and showed me each of the hijackers.… It boggles my mind that they had already had the hijackers identified.… Both metal detectors were open at that time, and lots of traffic was moving through. So picking people out is hard.… I wanted to know how they had that kind of information. So fast. It didn’t make sense to me.” (Trento and Trento 2006, pp. 37) Some of the hijackers are identified on the passenger manifests around this time (see (9:59 a.m.) September 11, 2001), and this knowledge is disseminated in the US intelligence community (see (1:00 p.m.) September 11, 2001 and (11:00 a.m.) September 11, 2001).

At the instruction of National Security Adviser Condoleezza Rice, Deputy Secretary of State Richard Armitage sends a cable out around the world saying the US government is still functioning. (Rice 9/8/2006) Having recently arrived at the Presidential Emergency Operations Center (PEOC) below the White House (see (Shortly Before 9:59 a.m.) September 11, 2001), the first thing that occurs to Rice, she will later say, is that it is important to get a cable out to all diplomatic posts around the world, to say the United States government has “not been decapitated by this attack.… I thought to myself, we need to let everybody know that we’re still up and running.” (Rice 9/11/2002) She therefore tells her deputy, Stephen Hadley, to call Armitage at the State Department, and urge him to send a cable to all overseas posts with this message. (Rice 8/1/2002 pdf file; Bumiller 2007, pp. xvi)

Passengers on Flight 93 continue struggling against the hijackers as they try to retake control of the plane, up to the point when the plane crashes. The passengers have been carrying out a sustained attempt to force their way into the cockpit and, in response, one of the hijackers apparently suggested flying the plane into the ground (see 9:57 a.m.-9:59 a.m. September 11, 2001 and 10:00 a.m.-10:02 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 13-14)
Hijackers Possibly Fight over the Plane's Controls - The cockpit voice recording from the plane will later reveal that a hijacker in the cockpit, speaking in Arabic, now gives the instruction: “Down, down. Pull it down! Pull it down!” (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 104) At this point, the 9/11 Commission Report will comment, the hijackers are still “at the controls, but must have judged that the passengers were only seconds from overcoming them.” (9/11 Commission 7/24/2004, pp. 14) The hijacker then shouts, “Down!” A hijacker, possibly the same one, exclaims: “Hey! Hey!” He then says: “Give it to me. Give it to me. Give it to me. Give it to me. Give it to me. Give it to me. Give it to me. Give it to me.” (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 104-105) This indicates that the hijackers might be fighting among themselves over the plane’s controls, Newsweek will suggest. (Breslau, Clift, and Thomas 12/3/2001)
Loud Air Noise Is Heard in the Cockpit - Over about the next 20 seconds, the cockpit voice recorder picks up the sounds of grunting and loud air noise. A hijacker then prays, saying: “Allah is the greatest! Allah is the greatest! Allah is the greatest! Allah is the greatest! Allah is the greatest!” The sound of a struggle is picked up by the cockpit voice recorder and a male passenger shouts loudly, “No!”
Passengers Are Apparently in the Cockpit When the Plane Crashes - While some people are screaming, a hijacker whispers: “Allah is the greatest! Allah is the greatest! Allah is the greatest! Allah is the greatest!” Finally, at 10:03 a.m. and 10 seconds, everything goes silent and the cockpit voice recording ends. (Federal Bureau of Investigation 12/4/2003; McMillan 2014, pp. 105) Flight 93 crashes in a field in Shanksville, Pennsylvania, one second later, according to the 9/11 Commission Report (see (10:03 a.m.-10:10 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 14, 30) In the final moments of the struggle, voices that previously seemed muffled and distant on the cockpit voice recording suddenly become clearer, according to relatives of Flight 93’s passengers who will hear the recording in 2002 (see April 18, 2002). These relatives will see this as evidence that passengers made it into the cockpit before the plane crashed. (Longman 2002, pp. 271; MSNBC 7/30/2002)

Vice President Cheney and other leaders now in the White House bunker begin receiving reports from the Secret Service of a presumably hijacked aircraft heading toward Washington. The Secret Service is getting this information about Flight 93 through links to the FAA. However, they are looking at a projected path, not an actual radar return, so they do not realize that the plane crashes minutes later. (9/11 Commission 6/17/2004)

The cockpit voice recording of Flight 93 was recorded on a 30-minute reel, which means that the tape is continually overwritten and only the final 30 minutes of any flight would be recorded. The government later permits relatives to hear this tape. Apparently, the version of the tape played to the family members begins at 9:31 a.m. and runs for 31 minutes, ending one minute before, according to the government, the plane crashes. (Longman 2002, pp. 206-207; Hirschkorn and Mattingly 4/19/2002) The New York Observer comments, “Some of the relatives are keen to find out why, at the peak of this struggle, the tape suddenly stops recording voices and all that is heard in the last 60 seconds or so is engine noise. Had the tape been tampered with?” (Sheehy 6/20/2004)

Flight 93’s transponder, which was switched off after Flight 93 was hijacked, is turned back on just before the plane crashes, thereby revealing the plane’s altitude to air traffic controllers at the FAA’s Cleveland Center. (Federal Bureau of Investigation 9/11/2001; MSNBC 9/11/2002) A transponder is a device that sends a plane’s identifying information, speed, and altitude to controllers’ radar screens. (Maraniss 9/16/2001) Flight 93’s transponder was switched off at around 9:40 a.m. (see (9:40 a.m.) September 11, 2001), although Cleveland Center controllers have still been able to follow Flight 93 on “primary radar,” which shows less information about a flight (see (9:41 a.m.-10:06 a.m.) September 11, 2001). (Federal Bureau of Investigation 1/8/2002; 9/11 Commission 7/24/2004, pp. 29; Sangiacomo 7/3/2011)
Plane Shown to Be Flying at 8,200 Feet - Flight 93’s transponder is reactivated at 10:02 a.m. and 50 seconds, and then stays on for “approximately 20 seconds,” according to “information from the flight data” provided to the FBI later today by Rick Kettell, the manager of the Cleveland Center. After the transponder is turned back on, Flight 93’s radar track is observed by Cleveland Center controllers Linda Justice and Stacey Taylor. The information from the transponder shows them that Flight 93 is at an altitude of 8,200 feet. (Federal Bureau of Investigation 9/11/2001; Federal Aviation Administration 9/16/2001 pdf file; 9/11 Commission 10/2/2003 pdf file)
Plane Soon Disappears from Radar Screens - Flight 93 will crash into the ground at 10:03 a.m. and 11 seconds, according to the 9/11 Commission Report, less than 30 seconds after the transponder is reactivated (see (10:03 a.m.-10:10 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 30) Cleveland Center controllers will see the plane completely disappear from their radar screens around that time. (MSNBC 9/11/2002) A Cleveland Center controller will then report, apparently over an FAA teleconference, that Flight 93’s transponder “came on briefly and then it went back off with the primary, and now we’ve lost him completely.” (Federal Aviation Administration 9/11/2001) “I had two radar hits on [Flight 93],” Taylor will recall, adding that she then “lost the primary target on [Flight 93] and we suspected it had gone down.” (Federal Aviation Administration 9/16/2001 pdf file) The reason Flight 93’s transponder is switched back on just before the plane crashes is unclear. Taylor will comment, a year after 9/11: “That’s something we’ve always wanted to know. Why did the transponder come back on?” She will say Cleveland Center controllers wondered this because they believed that “the hijackers had shut it off so that they couldn’t be tracked.” (MSNBC 9/11/2002)

The NORAD representative on the Pentagon’s air threat conference call reports that General Ralph Eberhart, the commander in chief of NORAD, has declared “concern” for the crisis that is taking place. At around 9:39 a.m., the NORAD representative said over the conference call that “[n]o assessment for the overall air situation” had been given by NORAD at that point (see (9:39 a.m.) September 11, 2001). But now he says an assessment has been issued. He reports over the conference call: “At this time, CINC [commander in chief] NORAD”—meaning Eberhart—“has declared an assessment of concern for the air events does hold. I say again, an assessment of concern does hold for the air events.” (US Department of Defense 9/11/2001; US Department of Defense 9/11/2001 pdf file) Eberhart will tell the 9/11 Commission that at NORAD, he alone would be responsible for making an assessment of concern. He will say that at around 9:40 a.m. to 9:45 a.m., he received a lot of pressure from personnel at NORAD’s Cheyenne Mountain Operations Center to say that “yes,” he did assess concern. If he makes an assessment of concern, Eberhart will comment, it triggers a “Defcon surge.” What he means by a “Defcon surge” is unclear. (9/11 Commission 3/1/2004) (The military’s defense readiness condition (Defcon) will in fact be raised to Defcon 3, on the orders of Secretary of Defense Donald Rumsfeld, at 10:52 a.m. (see (10:43 a.m.-10:52 a.m.) September 11, 2001). (US Department of Defense 9/11/2001 pdf file; 9/11 Commission 7/24/2004, pp. 326; Goldberg et al. 2007, pp. 131) ) Eberhart will also say that an assessment of concern is “tied basically to a foreign attack” and making it triggers a number of consequences that, among other things, would impact Russia. (9/11 Commission 3/1/2004)

In the tiny town of Boswell, about ten miles north and slightly to the west of Flight 93’s crash site, Rodney Peterson and Brandon Leventry notice a passenger jet lumbering through the sky at about 2,000 feet. They realize such a big plane flying so low in that area is odd. They see the plane dip its wings sharply to the left, then to the right. The wings level off and the plane keeps flying south, continuing to descend slowly. Five minutes later, they hear news that the plane has crashed. Other witnesses also later describe the plane flying east-southeast, low, and wobbly. (Longman and Thomas 9/14/2001; Longman 2002, pp. 205-206) “Officials initially say that it looks like the plane was headed south when it hit the ground.” (News Channel 5 (Cleveland) 9/11/2001)

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

Paula Pluta, a resident of Stonycreek Township, Pennsylvania, sees Flight 93 crashing behind some trees about 1,500 yards from her home and then calls 9-1-1, becoming the first person to call the emergency services to report the crash. (Pittsburgh Tribune-Review 9/12/2001; East Bay Times 9/10/2005) Pluta is at her home, watching television, unaware of the terrorist attacks on the World Trade Center and at the Pentagon. Everything has been quiet and normal. Suddenly, though, her house starts to vibrate, and things in it start rattling and shaking. She hears a roar coming from the skies above her that gets louder and louder. “I heard this noise like a dive bomber; you know, one of those planes they use in war,” she will later recall. When she looks out the living room window, though, she sees nothing unusual outside. She then goes out onto the front porch. From there, she sees a “silver streak” plummeting toward the ground at an angle of about 45 degrees. “It looked like a silver bullet,” she will describe. (Braun and Zitner 9/12/2001; McMillan 2014, pp. 106; Friends of Flight 93 National Memorial 3/17/2016) Flight 93 crashes into the ground at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). (Seelye 9/9/2011; National Park Service 5/2013, pp. 13 pdf file) Pluta is unable to see the impact, since the plane disappears behind a line of trees before hitting the ground, but she feels the ground shaking when the plane crashes. “It hit so hard that it almost took my feet out from underneath me,” she will recall. (Braun and Zitner 9/12/2001; McMillan 2014, pp. 106; Friends of Flight 93 National Memorial 3/17/2016) She also sees a huge fireball about 150 feet up in the air and a plume of smoke coming from behind the trees. (Keller and Yates 9/12/2001; National Park Service 3/2017, pp. 15 pdf file) The explosion damages the outside of her home. Pluta notices that a garage door has buckled and a latched window has been sucked open. She immediately calls 9-1-1 to report the incident. “Oh my God!” she tells the operator. “There was an airplane crash here!” She is the first of about 20 local residents to report the crash of Flight 93 to the authorities. She will promptly head to the site where the crash occurred and be surprised at the lack of wreckage there (see (After 10:03 a.m.) September 11, 2001). (Pittsburgh Tribune-Review 9/12/2001; McMillan 2014, pp. 106-107; Friends of Flight 93 National Memorial 3/17/2016)

According to the 9/11 Commission, the NMCC learns about the Flight 93 hijacking at this time. Since the FAA has not yet been patched in to the NMCC’s conference call, the news comes from the White House. The White House learned about it from the Secret Service, and the Secret Service learned about it from the FAA. NORAD apparently is still unaware. Four minutes later, a NORAD representative on the conference call states, “NORAD has no indication of a hijack heading to Washington, D.C., at this time.” (9/11 Commission 6/17/2004)

Smoke rising, minutes after Flight 93 crashes in Pennsylvania.Smoke rising, minutes after Flight 93 crashes in Pennsylvania. [Source: CNN]Exactly when Flight 93 crashes is unclear. According to NORAD, Flight 93 crashes at 10:03 a.m. (North American Aerospace Defense Command 9/18/2001) The 9/11 Commission gives an exact time of 11 seconds after 10:03 a.m. It will claim this “time is supported by evidence from the staff’s radar analysis, the flight data recorder, NTSB [National Transportation Safety Board] analysis, and infrared satellite data.” It does note that “[t]he precise crash time has been the subject of some dispute.” (9/11 Commission 6/17/2004) However, a seismic study authorized by the US Army and drafted by scientists Won-Young Kim and Gerald Baum to determine when the plane crashed will conclude that the crash happened at 10:06:05 a.m. (Kim and Baum 2002 pdf file; Perlman 12/9/2002) The discrepancy is so puzzling that the Philadelphia Daily News will publish an article on the issue, titled “Three-Minute Discrepancy in Tape.” This notes that leading seismologists agree on the 10:06 a.m. time, give or take a couple of seconds. (Bunch 9/16/2002) The New York Observer will note that, in addition to the seismology study, “The FAA gives a crash time of 10:07 a.m. In addition, the New York Times, drawing on flight controllers in more than one FAA facility, put the time at 10:10 a.m. Up to a seven-minute discrepancy? In terms of an air disaster, seven minutes is close to an eternity. The way our nation has historically treated any airline tragedy is to pair up recordings from the cockpit and air traffic control and parse the timeline down to the hundredths of a second. However, as [former Inspector General of the Transportation Department] Mary Schiavo points out, ‘We don’t have an NTSB (National Transportation Safety Board) investigation here, and they ordinarily dissect the timeline to the thousandth of a second.’” (Sheehy 2/15/2004)

The FBI is reportedly in “chaos,” in particular because its Critical Incident Response Group (CIRG) is stranded away from Washington, DC, being instead in California for a major training exercise. The CIRG would normally coordinate the FBI’s rapid response to a crisis incident, such as a terrorist attack. (NBC 4 9/11/2001; Darling 2010, pp. 73-75) But NBC News reports that the FBI has been “operating a massive exercise from their hostage rescue unit. All of their top teams, about 50 personnel, helicopters, equipment, [have been] in Monterey, California, for the last two days, scheduled to fly back today commercially. So all of those people are out of place.” (NBC 4 9/11/2001) USA Today will add that the day’s attacks are “so unexpected that a joint FBI/CIA anti-terrorist task force that specifically prepared for this type of disaster was on a training exercise in Monterey.” (Nichols 9/11/2001) NBC News concludes: “It’s fair to say, according to sources that we’ve talked to here at NBC, that the FBI rescue operations and other FBI operations are really in chaos right now, because they can’t reach their officials in New York, all of their phone lines are down. And now you’ve got all of their special experts on this stuck in Monterey, California.… So they are seriously out of pocket, and there is a real breakdown of the FBI anti-terror coordination team, which is of course the principal team that would lead any effort.” (NBC 4 9/11/2001) The US politics website will similarly conclude, “[J]ust as the worst terrorist act was being committed on American lives and property, the chief federal agency responsible for preventing such crimes was being AWOL.” (Evote [.com] 9/11/2001) The CIRG arrived in California the previous day for a week of special weapons and tactics (SWAT)-related field training (see September 10, 2001). Its members will be flown back to Washington around late afternoon on a specially arranged flight (see Late Afternoon September 11, 2001). (Darling 2010, pp. 75-76)
