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

The hole caused by the Flight 11 crash.The hole caused by the Flight 11 crash. [Source: Reuters]Flight 11 slams into the WTC North Tower (Building 1). Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. (CNN 9/12/2001; New York Times 9/12/2001; North American Aerospace Defense Command 9/18/2001; Cauchon 12/20/2001; Federal Emergency Management Agency 5/1/2002, pp. 1-10; Dwyer et al. 5/26/2002; Levin, Adams, and Morrison 8/13/2002; Associated Press 8/21/2002; Adcock 9/10/2002) The NIST report states the crash time to be 8:46:30. (National Institute of Standards and Technology 9/2005, pp. 19) The 9/11 Commission Report states the crash time to be 8:46:40. (9/11 Commission 7/24/2004, pp. 7) Investigators believe the plane still has about 10,000 gallons of fuel (see 8:57 a.m. September 11, 2001). (Dwyer et al. 5/26/2002) The plane strikes the 93rd through 99th floors in the 110-story building. No one above the crash line survives; approximately 1,360 people die. Below the crash line, approximately 72 die and more than 4,000 survive. Both towers are slightly less than half full at the time of the attack, with between 5,000 to 7,000 people in each tower. This number is lower than expected. Many office workers have not yet shown up to work, and tourists to the observation deck opening at 9:30 A.M. have yet to arrive. (Cauchon 12/20/2001; National Institute of Standards and Technology 9/2005, pp. 20-22) The impact severs some columns on the north side of the North Tower. Each tower is designed as a “tube-in-tube” structure and the steel columns which support its weight are arranged around the perimeter and in the core. The plane, which weighs 283,600 lb and is traveling at an estimated speed of around 430 mph (see October 2002-October 2005), severs 35 of the building’s 236 perimeter columns and damages another two. The damage to the South Tower’s perimeter will be similar (see 9:03 a.m. September 11, 2001). (National Institute of Standards and Technology 9/2005, pp. 5-9, 20, 22) The perimeter columns bear about half of the tower’s weight, so this damage reduces its ability to bear gravity loads by about 7.5 percent. (National Institute of Standards and Technology 9/2005, pp. 6) The actual damage to the 47 core columns is not known, as there are no photographs or videos of it, but there will be much speculation about this after 9/11. It will be suggested that some parts of the aircraft may have damaged the core even after crashing through the exterior wall. According to the National Institute of Standards and Technology (NIST): “Moving at 500 mph, an engine broke any exterior column it hit. If the engine missed the floor slab, the majority of the engine core remained intact and had enough residual momentum to sever a core column upon direct impact.” (National Institute of Standards and Technology 9/2005, pp. 107) According to NIST’s base case computer model, three of the core columns are severed and another ten suffer some damage. (National Institute of Standards & Technology 9/2005, pp. 189 pdf file) If this is accurate, it means that the impact damage to the core reduces the Tower’s strength by another approximately 7.5 percent, meaning that the building loses about 15 percent of its strength in total. This damage will be cited after 9/11 by NIST and others researchers as an event contributing to the building’s collapse (see October 23, 2002 and October 19, 2004). In addition, some of the fireproofing on the steel columns and trusses may be dislodged. The original fireproofing on the fire floors was mostly Blazeshield DC/F, but some of the fireproofing on the flooring has recently been upgraded to Blazeshield II, which is about 20 percent denser and 20 percent more adhesive. (National Institute of Standards & Technology 9/2005, pp. xxxvi, 83 pdf file) Photographs and videos of the towers will not show the state of fireproofing inside the buildings, but NIST will estimate the damage to it using a computer model. Its severe case model (see (October 2002-October 2005)) will predict that 43 of the 47 core columns are stripped of their fireproofing on one or more floors and that fireproofing is stripped from trusses covering 60,000 ft2 of floor area, the equivalent of about one and a half floors. NIST will say that the loss of fireproofing is a major cause of the collapse (see April 5, 2005), but only performs 15 tests on fireproofing samples (see October 26, 2005). (National Institute of Standards and Technology 9/2005, pp. 23) According to NIST, more fireproofing is stripped from the South Tower (see 9:03 a.m. September 11, 2001).

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

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

Carl Truscott.Carl Truscott. [Source: ASERO Worldwide]Carl Truscott, the Secret Service special agent in charge of the presidential protective division (PPD), sees coverage of the plane crash at the World Trade Center on television, and calls several colleagues to his office for a meeting to discuss how to respond to the crisis. (United States Secret Service 10/1/2001) Truscott is responsible for the overall security of the president, the first family, and the White House. (United States Secret Service 4/1/2004 pdf file) He is in his office at the Eisenhower Executive Office Building, which is located next to the West Wing of the White House and is where most of the president’s staff works. Truscott will later recall that he has “observed the CNN broadcast of the aircraft crashing into the World Trade Center.” (United States Secret Service 10/1/2001; WBKO 12/19/2007; Baker 1/8/2009) It is unclear if he is referring to the first crash at the WTC, which occurred at 8:46 a.m. (see 8:46 a.m. September 11, 2001) but was first reported on CNN at 8:48 a.m. (see 8:48 a.m. September 11, 2001), or the second crash, which was broadcast live at 9:03 a.m. (see 9:03 a.m. September 11, 2001). (Fox News 9/11/2003; Bamford 2004, pp. 16) Truscott then telephones and pages three senior Secret Service agents, and asks them to come to his office for a meeting to discuss security enhancements at the White House. The names of the three agents are unstated, but they are a deputy special agent in charge of the PPD, an assistant to the special agent in charge of the PPD, and an assistant division chief of the Secret Service’s technical security division, which “evaluates and implements technology-based protective countermeasures to safeguard Secret Service protectees and protected facilities, including the White House and [the] vice president’s residence.” The meeting will begin at around 9:18 a.m., according to Truscott (see (9:18 a.m.) September 11, 2001). (United States Secret Service 10/1/2001; United States Secret Service 9/20/2004 pdf file)

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

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

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

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

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

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

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

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

Personnel on Air Force One, the president’s plane, are unclear about what is happening in the United States and receive a number of incorrect reports about the terrorist attacks, leading one officer to wonder if a nation-state is responsible for the attacks. (Graff 9/9/2016) Air Force One is currently on the ground at Sarasota-Bradenton International Airport in Florida. (US President 9/2001; Tillman 2/29/2012 pdf file) Master Sergeant Dana Lark, superintendent of communications on the plane, followed the television coverage of the first crash at the World Trade Center and then saw the second plane hitting the WTC live on TV, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). However, she and her colleagues are unable to acquire precise information about what is happening. She will later recall: “We still didn’t know what the hell was going on. We’re just monitoring the Secret Service and staff radio channels. It was chaos. What’s next?” They subsequently receive inaccurate reports about the attacks. “All of a sudden, other reports start coming in—explosion at the White House, car bomb at the State Department” (see (Between 9:50-10:40 a.m.) September 11, 2001), Lark will say. In the confusion, Lark wonders if a nation-state such as Russia is responsible for what is happening. “I’m thinking Cold War, the big bad Soviet bear,” she will recall. “This was an extensive attack. Could this be a nation-state?” Even after Air Force One takes off from the Sarasota airport, at around 9:55 a.m. (see 9:54 a.m. September 11, 2001), personnel on the plane continue receiving incorrect reports and remain unclear about what is going on. “As we’re taking off, you’re still getting all this misinformation” and “[y]our head was spinning, trying to figure out what had actually happened,” Lark will describe. “The only thing we knew for sure, because we’d seen it with our own eyes,” according to Lark, “was that the World Trade Center had been hit.” (Graff 9/9/2016)

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

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

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

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

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

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

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

Secret Service executives implement an “emergency call-up” of all their agency’s personnel at some time after 9:37 a.m., when the Pentagon was hit, according to US News and World Report. The reason why the Secret Service did not call up all its personnel earlier on is unstated, as is the reason it decides to do so now. (Ragavan 12/1/2002) The Secret Service is responsible for protecting the nation’s “most visible targets,” including the president, the vice president, and the White House complex. (US Department of the Treasury 5/8/2001; Office of Management and Budget 7/2001, pp. 82 pdf file) Brian Stafford, the agency’s director, realized the US was under attack after the second plane hit the World Trade Center at 9:03 a.m. (see 9:03 a.m. September 11, 2001), and then activated the Director’s Crisis Center at Secret Service headquarters to manage the agency’s response (see (Shortly After 9:03 a.m.) September 11, 2001). (United States Secret Service 10/1/2001; Peter Schnall 10/24/2004) And since around 9:18 a.m., a meeting has been taking place in the office of Carl Truscott, the special agent in charge of the presidential protective division, during which Truscott and three other senior Secret Service agents have discussed security enhancements at the White House (see (9:18 a.m.) September 11, 2001). (United States Secret Service 10/1/2001)

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

Bush boards Air Force One in Sarasota, Florida, waving to people below as if the day were like any other.Bush boards Air Force One in Sarasota, Florida, waving to people below as if the day were like any other. [Source: Agence France-Presse]President Bush and his entourage arrive at Sarasota-Bradenton International Airport, where Air Force One is waiting, and Bush hurriedly gets onto his plane. (BBC 9/1/2002; 9/11 Commission 7/24/2004, pp. 39) Bush left the Emma E. Booker Elementary School in Sarasota, Florida, at around 9:35 a.m. to be driven to Air Force One (see (9:34 a.m.) September 11, 2001). (Langley 12/16/2001; Bloomberg 6/17/2004)
Limousine Stops Right by Air Force One - His limousine now speeds past the airport’s main entrance, goes north, and veers down a tiny road leading to the airport, ignoring a sign that states, “No Airport Access.” It then passes through a small, unmarked gate in a chain-link fence and races across the tarmac toward Air Force One. It swings around the plane’s tail and stops behind the left wing. (Sammon 2002, pp. 98-99) The motorcade arrives at the airport between 9:42 a.m. and 9:45 a.m., according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 39) According to journalist and author Bill Sammon, Bush’s limousine reaches the airport at 9:43 a.m. (Sammon 2002, pp. 99; Sammon 10/8/2002)
Plane's Engines Are Already Running - Colonel Mark Tillman, the pilot of Air Force One, started two of the plane’s four engines while Bush was on his way to the airport. White House chief of staff Andrew Card will later comment that he is “struck that the engines on Air Force One [are] running” when the motorcade reaches the airport, since this is “normally a protocol no-no.” (Tillman 9/11/2011; Graff 9/9/2016) “Usually you don’t start the engine until the president is already on the plane,” he will say. (BBC 9/9/2011)
President Usually Takes His Time Saying Goodbye - Normally, when his motorcade arrives at Air Force One, the president “emerges from the limo, waves to the crowd behind barricades, thanks hosts who have accompanied him, and shakes hands with the airport personnel and guests who’ve come to see him off,” Karl Rove, Bush’s senior adviser, will write. The president then “walks alone up the steps to Air Force One at a leisurely pace, stopping to wave again to the people on the tarmac.” The other people in the motorcade usually only start to get on board once he is on the plane. (Rove 2010, pp. 252)
Bush Hurries up the Stairs onto Air Force One - Today, though, the Secret Service wants to get the president onto Air Force One as quickly as possible. (Graff 9/9/2016) Bush therefore walks briskly up the long mobile staircase behind the left wing. (Sammon 2002, pp. 99; Walsh 2003, pp. 207) He is “just trucking up the stairs” without his usual “Texas swagger,” Tillman will describe. (Graff 9/9/2016) He does find time, however, to pause at the doorway to wave to photographers before entering the plane. (Martin 7/4/2004) Once he is on board, he goes to his private cabin near the front of the aircraft. A Secret Service agent tells him, “Mr. President, we need you to get seated as soon as possible.” Bush then straps himself in, ready for takeoff. (Woodward 2002, pp. 16)
Chief of Staff Is Frustrated by the Passengers Delaying Takeoff - Meanwhile, everyone who is traveling on Air Force One apart from Bush and his senior staff boards the plane through its back stairs. But before doing so they are subjected to a strict security check (see (9:45 a.m.-9:53 a.m.) September 11, 2001). (Sammon 2002, pp. 99; Graff 9/9/2016) Card becomes frustrated that takeoff is being delayed due to the time it takes to get so many passengers onto the plane. (Card 8/16/2002; Adair and Hegarty 9/8/2002) Air Force One will take off unusually quickly once all the passengers are on board. (Keil 9/2004; Graff 9/9/2016) It usually takes another 15 minutes after everyone has boarded for the passengers to get seated, the doors to be closed, and the engines to power up, according to Rove. (Rove 2010, pp. 252) But today Air Force One will take off about 10 minutes after Bush’s motorcade reaches the airport, at around 9:55 a.m. (see 9:54 a.m. September 11, 2001). (Balz and Woodward 1/27/2002; 9/11 Commission 7/24/2004, pp. 39)

A television broadcast falsely describes smoke coming from Washington Mall instead of its true source, the Pentagon.A television broadcast falsely describes smoke coming from Washington Mall instead of its true source, the Pentagon. [Source: CNN]There are numerous false reports of additional terror attacks. Before 10:00 a.m., some hear reports on television of a fire at the State Department. At 10:20 a.m., and apparently again at 10:33 a.m., it is publicly reported this was caused by a car bomb. (Ottawa Citizen 9/11/2001; Langley 12/16/2001; Miller 8/26/2002) At 10:23 a.m., the Associated Press reports, “A car bomb explodes outside the State Department, senior law enforcement officials say.” (Miller 8/26/2002) Counterterrorism “tsar” Richard Clarke hears these reports at this time and asks Deputy Secretary of State Richard Armitage in the State Department to see if the building he’s in has been hit. Armitage goes outside the building, finds out there’s no bomb, and calls his colleagues to inform them that the reports are false. Reports of a fire on the Capitol Mall also appear and are quickly found to be false. (ABC News 9/15/2002; Clarke 2004, pp. 8-9) There are numerous other false reports over the next hour, including explosions at the Capitol building and USA Today headquarters. (Miller 8/26/2002) For instance, CNN reports an explosion on Capitol Hill at 10:12 a.m. CNN then announces this is untrue 12 minutes later. (Ottawa Citizen 9/11/2001)

Mark Tillman.Mark Tillman. [Source: US Air Force]Colonel Mark Tillman, the pilot of Air Force One, is warned about an unidentified man, possibly carrying a gun, who is standing at the end of the runway at the airport in Sarasota, Florida, as he is preparing to take off with President Bush on the plane. (Shawn 9/6/2011; Tillman 2/29/2012 pdf file) Bush arrived at Sarasota-Bradenton International Airport after being driven away from the Emma E. Booker Elementary School and is now on Air Force One (see (9:43 a.m.) September 11, 2001). (Sammon 2002, pp. 98-99; Martin 7/4/2004) While the plane’s crew members were waiting for him to arrive, they were told there was “great potential that we are going to be under attack sitting on the ramp” and they received “reports of unidentified people all around the airport,” according to Tillman (see (9:04 a.m.-9:55 a.m.) September 11, 2001). (Tillman 9/11/2011)
Secret Service Alerts Pilot to Man Carrying a 'Long Gun' - Now, as Air Force One is taxiing out for takeoff, Tillman receives a warning from the Secret Service about an unidentified man who is standing by the fence at the end of the runway and carrying some type of device. The Secret Service “didn’t know what the gentleman had, but he had something in his hand; they thought it might have been a long gun,” Tillman will later recall. (Shawn 9/6/2011) “It is almost impossible to defend against a long gun if he’s going to shoot me on the ground,” Tillman will note. He is told that “shooters have [the unidentified man] in sight” and “will take him down if he moves.” He is instructed, “[P]lease, do not taxi by him and take off,” even though the direction of the prevailing wind would normally lead to the plane going by the man while taking off. (Tillman 2/29/2012 pdf file) Tillman therefore has to launch in the opposite direction, with a tail wind, in order to stay away from the man. (McMillin 11/13/2012)
Plane Takes Off 'Like a Rocket' - Air Force One will take off at about 9:54 a.m. (see 9:54 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 39) Tillman will climb the plane steeply. This, he will say, is “what we needed to do to make sure that [the man] didn’t have a correct line of sight to fire at the aircraft.” (Peter Schnall 1/25/2009) “I start hauling down the runway,” he will describe. “Pull back, went up at about 8,000 feet per minute, and just put the plane on its tail, rolled it off towards the Gulf of Mexico, because I didn’t want the shooter to get us.” (Tillman 2/29/2012 pdf file) White House communications director Dan Bartlett, who is on Air Force One, will note that the plane takes off “like a rocket.” He will recall that “for a good 10 minutes, the plane was going almost straight up.” (Bartlett 8/12/2002) White House adviser Karl Rove, who is also on Air Force One, will comment that he has not previously “been in a jet at such a steep incline.” He will also say the Secret Service is “concerned about the possibility of terrorists with shoulder-launched ground-to-air missiles” and it therefore wants the plane “out of range quickly.” (Rove 2010, pp. 252-253)
Suspicious Man Found to Be Not a Threat - The fear over the unidentified man at the end of the runway will turn out to be unfounded. The man, according to Tillman, is just someone who has come to the airport with his children to see Air Force One leaving Sarasota, and the device he is carrying is just a video camera.

Air Force One departs Sarasota.Air Force One departs Sarasota. [Source: Associated Press]Air Force One takes off from off from Sarasota-Bradenton International Airport in Florida with President Bush on board. (Keen and Carney 9/11/2001; Balz and Woodward 1/27/2002; 9/11 Commission 7/24/2004, pp. 39) The plane takes off without any fighter jets protecting it. “The object seemed to be simply to get the president airborne and out of the way,” an administration official will later say. (Langley 12/16/2001) There are still 3,520 planes in the air over the US. (Adams, Levin, and Morrison 8/13/2002) About half of the planes in the Florida region where Bush’s plane is are still airborne. (Heller 9/7/2002) Apparently, fighters don’t meet up with Air Force One until over an hour and a half later (see (11:29 a.m.) September 11, 2001). Counterterrorism “tsar” Richard Clarke will claim to have heard at around 9:50 a.m. from the White House bunker containing Vice President Dick Cheney that a fighter escort had been authorized. (Clarke 2004, pp. 8-9)

Thomas Gould.Thomas Gould. [Source: Nathan Lipscomb / US Air Force]A discussion takes place on Air Force One between Andrew Card, the White House chief of staff, Edward Marinzel, the head of President Bush’s Secret Service detail, Lieutenant Colonel Thomas Gould, Bush’s military aide, and Colonel Mark Tillman, the pilot, about where the president’s plane should go. (9/11 Commission 7/24/2004, pp. 39) Air Force One’s original flight plan had Washington, DC, as the destination. (White House 8/29/2002) And Bush has been anxious to return to Washington, to lead the government’s response to the terrorist attacks. (Card 8/12/2002; Card 8/16/2002; Bush 2010, pp. 130) But when it took off from Sarasota-Bradenton International Airport in Florida (see 9:54 a.m. September 11, 2001), Air Force One had no fixed destination. According to the 9/11 Commission Report, the objective had been “to get up in the air—as fast and as high as possible—and then decide where to go.”
Washington Considered 'Too Unstable for the President to Return' - Now, in the discussion, it is decided that the plane should head somewhere other than Washington. Marinzel says he feels “strongly that the situation in Washington [is] too unstable for the president to return there” and Card agrees with him, according to the 9/11 Commission Report. (Card 8/12/2002; 9/11 Commission 7/24/2004, pp. 39) Mark Rosenker, the director of the White House Military Office, who is also on Air Force One, will recall that the decision to head to a destination other than Washington is “made based on the fact that the Pentagon had been hit, Washington was now clearly a target. There were a host of reports coming in that we could not tell [if they] were factual or not.” There is therefore “a consensus type of a decision made that perhaps we should look at an alternative site, clear the fog, and then make the final decision on where we would be going.” (It is unclear, however, whether Rosenker participates in the meeting between Card, Marinzel, Gould, and Tillman.) (White House 8/29/2002)
President Reluctantly Accepts Decision - The time when the discussion of Air Force One’s destination takes place is unclear. Apparently describing this meeting, Card will say it takes place “up in the bedroom compartment” of the plane during the first “maybe five or 10 minutes of the flight,” meaning between around 9:55 a.m. and 10:05 a.m. (Card 8/16/2002) But according to the 9/11 Commission Report, it takes place at about 9:45 a.m. (9/11 Commission 7/24/2004, pp. 39) After the meeting, Bush will reluctantly accept the advice he is given, to head for a destination other than Washington, and at around 10:10 a.m. Air Force One will change course and fly west (see (10:10 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 315; Bush 2010, pp. 130)

Two F-16s belonging to the 147th Fighter Wing.Two F-16s belonging to the 147th Fighter Wing. [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. (BBC 9/1/2002; Kohn 9/11/2002; Bombardier 9/8/2006 pdf file; Rosenfeld and Gross 2007, pp. 40)
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)

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

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

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)

Air Force One, the president’s plane, changes course and heads west instead of north toward Washington, DC, but it currently has no specific destination. (9/11 Commission 7/24/2004, pp. 325) Washington had been Air Force One’s original destination. (White House 8/29/2002; Scully 9/11/2011) And President Bush has been anxious to return to the capital. (Card 8/12/2002; Card 8/16/2002) But when it took off from Sarasota-Bradenton International Airport in Florida (see 9:54 a.m. September 11, 2001), Air Force One had no fixed destination. There has been a discussion between the plane’s pilot, the lead Secret Service agent on the plane, Bush’s military aide, and Bush’s chief of staff, about where to go, and it was decided that Washington was too unsafe to be their destination (see (9:55 a.m.-10:04 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 39) This decision is now passed on to the president.
President Notified of Decision to Change Course - In his 2010 memoir, Bush will recall that “[s]hortly after we took off from Sarasota,” Andrew Card, his chief of staff, and Edward Marinzel, the lead Secret Service agent, “said conditions in Washington were too volatile, the danger of attack too high. The FAA believed six planes had been hijacked, meaning three more could be in the air.” (Bush 2010, pp. 130) Card tells Bush: “We’ve got to let the dust settle before we go back. We’ve got to find out what’s going on.” (Card 8/16/2002) Bush tells Card and Marinzel he is “not going to let terrorists scare me away.” He says: “I’m the president. And we’re going to Washington.” However, Card and Marinzel refuse to back down. (Bush 2010, pp. 130) Finally, “Bush reluctantly acceded” to their advice, and so “Air Force One changed course and began heading due west,” according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 325) Bush wants to know where they are now going. Card tells him that their new destination is still being decided. (Card 8/16/2002)
Plane Turns West within '20 Minutes of Takeoff' - Air Force One begins heading west “at about 10:10,” according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 325) A reporter who is traveling on Air Force One at this time will write that the plane “suddenly veered west” within “perhaps 20 minutes of takeoff,” meaning before 10:15 a.m. Describing the plane’s initial route after taking off, this reporter will write, “Assuming that a direct flight from Sarasota to Barksdale Air Force Base [in Louisiana] would have taken us over the Gulf of Mexico, we can conclude that we flew east (to within sight of the Atlantic Ocean), then north, then west.” (Keen and Carney 9/11/2001) However, a few accounts will claim that Air Force One continues flying toward Washington at this time, and only changes course and heads west at around 10:45 a.m. (see (10:45 a.m.) September 11, 2001). (Sammon 2002, pp. 108-109; Balz and Woodward 1/27/2002; National Journal 8/31/2002) At around 10:20 a.m., according to the 9/11 Commission Report, Barksdale Air Force Base will be identified “as an appropriate interim destination,” and so Air Force One heads toward there (see (10:20 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 325)

Michael Irwin.Michael Irwin. [Source: Publicity photo]Lieutenant Colonel Thomas Gould, a military aide who is accompanying President Bush on his visit to Florida, makes a call requesting a fighter escort and other assets to support Air Force One as it flies away from Sarasota. Gould, who has tactical control of all the military assets that support the president, including presidential aircraft, was with Bush on Air Force One when the plane took off from Sarasota-Bradenton International Airport (see 9:54 a.m. September 11, 2001). He has talked with Colonel Mark Tillman, Air Force One’s pilot, about the plane’s ability to evade other aircraft. “At this point we don’t know the scope of this attack and what’s in front of us,” Gould will later recall. Gould will say that because he “thought there was a threat,” he makes a phone call and asks for three things: fighter jets to escort Air Force One, a refueling plane, and an AWACS (Airborne Warning and Control System plane) to provide the ability to “see” around the president’s plane.
Request Relayed over Conference Call - Gould will say, in 2011, that he calls the Pentagon to make this request. (Scully 9/11/2011; Wallace 9/11/2011) However, other evidence indicates that he contacts the Presidential Emergency Operations Center (PEOC) below the White House with the request, and the request is then passed on to the Pentagon over the air threat conference call. A transcript of the air threat conference call shows that at 10:14 a.m., Colonel Michael Irwin, the director of operations for the White House Military Office, who is in the PEOC, says he has “just talked to [the] mil aide” on Air Force One, and then adds: “We’d like AWACS over Louisiana. We’d like fighter escort.” (US Department of Defense 9/11/2001 pdf file)
Fighters and AWACS Later Accompany Air Force One - An AWACS on a training mission off the coast of Florida is directed toward Air Force One and will accompany it all the way to Washington, DC (see Before 9:55 a.m. September 11, 2001). (Code One Magazine 1/2002) Fighters will also arrive to escort the president’s plane. However, it will be over an hour before they reach it (see (11:29 a.m.) September 11, 2001). (Keen and Carney 9/11/2001) It is unclear if and when a refueling plane reaches Air Force One.

President Bush’s travels on 9/11.President Bush’s travels on 9/11. [Source: Yvonne Vermillion / MagicGrapix.com]Air Force One begins heading for Barksdale Air Force Base in Louisiana after the base is identified as a suitable interim destination for the president’s plane. (9/11 Commission 7/24/2004, pp. 325) Washington, DC, was the plane’s original destination. (White House 8/29/2002; Scully 9/11/2011) But after taking off from Sarasota-Bradenton International Airport in Florida without a fixed destination (see 9:54 a.m. September 11, 2001), Air Force One changed course at around 10:10 a.m. and headed west (see (10:10 a.m.) September 11, 2001). This was because it had been determined that Washington was too unsafe for President Bush to return there (see (9:55 a.m.-10:04 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 39, 325) At that time, the plane’s new destination was undecided.
Military Base Sought for President to Make a Statement - Andrew Card, Bush’s chief of staff, who is with the president on Air Force One, will later recall, “And so we started looking at potential Air Force bases or Navy bases where we could land the plane.” (Card 8/16/2002) Mark Rosenker, the director of the White House Military Office, will recall that Card comes up to him in the communications area of the plane and says, “We need to find a facility, a base that we can get to in a relatively short period of time so that the president can make a statement.” (White House 8/29/2002)
Secret Service Told of Bush's Desire to Land - Card will recall: “I had a goal of landing the plane within an hour and a half. It was somewhat arbitrary, but I wanted to get the president down.” (Card 8/16/2002) Card similarly tells Edward Marinzel, the head of the president’s Secret Service detail, that Bush wants to land so he can make a statement to the press. It is also noted “that the stop would provide an opportunity for the airplane to be refueled and those on board to effect necessary communication,” Marinzel will say. (United States Secret Service 2001)
Offutt Air Base Rejected as Destination - Lieutenant Colonel Thomas Gould, Bush’s military aide, quickly researches the possibilities. (9/11 Commission 7/24/2004, pp. 325) The first plan that is considered, according to Rosenker, is to fly all the way out to Offutt Air Force Base in Nebraska, but this idea is dismissed because it would take too long to get there, and it is “very important to the president to address the nation and make sure that the people could see that he was safe and in total control of the situation.” (White House 8/29/2002) (Air Force One will in fact head to Offutt later in the day, landing there at 2:50 p.m. (see 2:50 p.m. September 11, 2001).)
Barksdale Makes 'the Greatest Sense' - Instead, at around 10:20 a.m., Gould identifies Barksdale Air Force Base as “an appropriate interim destination,” according to the 9/11 Commission Report. (9/11 Commission 7/24/2004, pp. 325-326) Rosenker will recall: “Barksdale made the greatest sense to us. It was a highly secure Air Force base, had B-52s there; they had the capability to do what was necessary to secure Air Force One and to make sure that the president was safe, and make sure that we could provide the appropriate communications facility so the president could make his statement.” (White House 8/29/2002)
Bush Agrees with Decision to Head to Barksdale - The final decision to head to Barksdale Air Base is made by Card, “after talking to the military and the Secret Service,” according to White House press secretary Ari Fleischer. (Fleischer 2005, pp. 142) Bush agrees with the decision and Barksdale becomes his plane’s new destination. (Bush 2010, pp. 130; Rove 2010, pp. 255) Air Force One will land at Barksdale Air Force Base at around 11:45 a.m. (see 11:45 a.m. September 11, 2001). (9/11 Commission 7/24/2004, pp. 325)

Personnel at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York, learn that Air Force One is airborne, around half an hour after it took off from Florida, and are told the plane is heading toward Washington, DC. (North American Aerospace Defense Command 9/11/2001; North American Aerospace Defense Command 9/11/2001; 9/11 Commission 7/24/2004, pp. 325)
NEADS Learns President's Plane Is Airborne - Major Kevin Nasypany, the mission crew commander at NEADS, is briefed by a colleague that “Air Force One is airborne out of Florida, heading to Washington.” This is apparently the first time NEADS knows that the president’s plane is in the air. (North American Aerospace Defense Command 9/11/2001; North American Aerospace Defense Command 9/11/2001) But Air Force One took off from Sarasota-Bradenton International Airport in Florida about half an hour ago (see 9:54 a.m. September 11, 2001). (Balz and Woodward 1/27/2002; 9/11 Commission 7/24/2004, pp. 325) And while some later accounts will state that the plane is indeed heading north, toward Washington, at this time (see (10:45 a.m.) September 11, 2001), according to other accounts, including the 9/11 Commission Report, it has turned west (see (10:10 a.m.) September 11, 2001) and is now flying toward Barksdale Air Force Base in Louisiana (see (10:20 a.m.) September 11, 2001). (Keen and Carney 9/11/2001; Sammon 2002, pp. 108; Balz and Woodward 1/27/2002; 9/11 Commission 7/24/2004, pp. 325)
Commander Told Fighters Will Escort Air Force One - Nasypany’s colleague continues: “We’ve got those four F-15s coming out of Langley. They’re done rolling.” (North American Aerospace Defense Command 9/11/2001) He is presumably referring to F-15 fighter jets belonging to the 1st Fighter Wing at Langley Air Force Base in Virginia. (Langley Air Force Base 11/2003; Airman 9/2005) He says, “Two of [the F-15s] will be diverted to escort [Air Force One] at the appropriate time.” Nasypany says, “We need a plane out of the Air Force One.” He then asks his colleague, “Is he airborne now?” The colleague says yes.
Commander Told SEADS Is Providing Fighter Escort - Nasypany then says, “We’ve identified [Air Force One] as a special one.” His colleague replies: “We haven’t got him. Southeast does,” meaning NORAD’s Southeast Air Defense Sector (SEADS) at Tyndall Air Force Base, Florida. Referring to SEADS, Nasypany asks, “So they’ll have fighters on him?” His colleague says yes. (North American Aerospace Defense Command 9/11/2001) However, fighters will only be noticed escorting Air Force One by those on the plane more than an hour later (see (11:29 a.m.) September 11, 2001). (Keen and Carney 9/11/2001)
Commander Passes on News about Air Force One - Nasypany then passes on the information about Air Force One to another colleague. He tells them: “Air Force One is airborne out of Florida, going to Washington. There should be F-15s on them by the time they hit our AOR [area of responsibility].” Nasypany restates that the president’s plane is “going to Washington. This is what I was just passed.” He says, “SEADS should be putting fighters on it,” but adds that “we’ll have to take over [in providing a fighter escort for Air Force One] once they hit our AOR.” (North American Aerospace Defense Command 9/11/2001)

A US Park Police helicopter that has been assisting in the response to the Pentagon attack has to respond to a sudden influx of reports of emergencies that are in fact false alarms. (Bohn 11/19/2001; Goldberg et al. 2007, pp. 164) The helicopter, with the call sign “Eagle II,” is one of two Park Police Aviation Unit helicopters that arrived at the Pentagon shortly after the attack there (see Shortly After 9:37 a.m. September 11, 2001). (NBC 4 9/11/2003; Goldberg et al. 2007, pp. 161-162) After transporting two patients from the Pentagon to the Washington Hospital Center, Eagle II returned to the aviation unit’s hangar in Anacostia Park to pick up a Secret Service agent. (McDonnell 2004, pp. 22 pdf file) Sergeant Keith Bohn, the pilot of Eagle II, will later recall: “The Secret Service had some requests for us to check. Things like the White House perimeter, the downtown areas, the rooftops. There were a lot of things coming up.” Suddenly, the helicopter has to respond to a mass of reports of additional emergencies. According to Bohn, “All of a sudden, everything was just unbelievable—to check bridges for abandoned cars, which were believed to be packed with explosives.” Eagle II is then “running from one report of things to another report.” These reported emergencies turn out to be false alarms. According to Bohn, “Actually, in the city [of Washington, DC], nothing else, in essence, happened that day, but… lots of fear was running rampant.” Bohn will add, “We were chasing our tail and everyone else’s all around town from Memorial Bridge, 14th Street Bridge, the White House; the Capitol was involved in wanting some perimeter checks, doing all that.” (Bohn 11/19/2001; Goldberg et al. 2007, pp. 164) Numerous emergencies in the Washington area are being incorrectly reported around this time (see (Between 9:50-10:40 a.m.) September 11, 2001). (Miller 8/26/2002)

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

Air Force One, with President Bush on board, changes course and heads west toward Barksdale Air Force Base in Louisiana around this time, according to some reports, significantly later than is claimed in other accounts, such as the 9/11 Commission Report. (Sammon 2002, pp. 108-109; Balz and Woodward 1/27/2002; 9/11 Commission 7/24/2004, pp. 325) The president’s plane is currently flying off the coast of South Carolina and is about half way through its 900-mile journey from Sarasota, Florida (see 9:54 a.m. September 11, 2001), to Washington, DC, according to journalist and author Bill Sammon. (Sammon 2002, pp. 109) At 10:41 a.m., Vice President Dick Cheney called Bush from the White House and urged him not to come back to Washington, because, Cheney told Bush, the capital was still too unsafe for him to return there (see 10:41 a.m. September 11, 2001). (Sanger and van Natta 9/16/2001; Balz and Woodward 1/27/2002)
Air Force One Turns West - According to the 9/11 Commission Report, Air Force One changed course and headed west at around 10:10 a.m. (see (10:10 a.m.) September 11, 2001), and it began flying toward Barksdale Air Force Base at about 10:20 a.m. (see (10:20 a.m.) September 11, 2001). (9/11 Commission 7/24/2004, pp. 325) However, Sammon will write that Bush gives the order to divert his plane after receiving the 10:41 a.m. call from Cheney. (Sammon 2002, pp. 108-109) “Within minutes” of Cheney calling Bush, according to the Washington Post, “those on board the president’s plane could feel it bank suddenly and sharply to the left, its course now westerly toward Barksdale Air Force Base.” (Balz and Woodward 1/27/2002) Barksdale is about 800 miles away, according to Sammon. (Sammon 2002, pp. 109) Representative Dan Miller (R-FL), who is on Air Force One, will support the claim that the plane changes course at this time, around 10:45 a.m. According to the St. Petersburg Times, Miller thought Air Force One “flew due north for about 45 minutes. Then it turned west.” (Martin 7/4/2004) Miller will tell the National Journal, “I would say 10:45, maybe 10:30 or so, the plane changed course.” (National Journal 8/31/2002)
Other Evidence Indicates Plane Is Already Flying West - However, in addition to the 9/11 Commission Report, several other accounts will indicate that Air Force One turned west and headed toward Barksdale Air Force Base significantly earlier than this. A reporter who is on Air Force One will write that the plane “suddenly veered west” within “perhaps 20 minutes of takeoff,” meaning before 10:15 a.m. (Keen and Carney 9/11/2001) And Ann Compton, another reporter on Air Force One, writes in her notebook that at 10:29 a.m., “We were not en route to Washington.” (Gilbert et al. 2002, pp. 131-132) Furthermore, at 10:42 a.m., an ID technician at NORAD’s Northeast Air Defense Sector (NEADS) received a call about Air Force One, in which they were told, “It looks like he’s going westbound now.” The caller, someone at NORAD’s Southeast Air Defense Sector (SEADS), added that the plane was “west of Tallahassee,” which is in north Florida, and said, “We called [the FAA’s Jacksonville Center] to see if he was deviating and they said he, it’s unknown where he’s going at this time.” (North American Aerospace Defense Command 9/11/2001)

A member of staff at NORAD’s Northeast Air Defense Sector (NEADS) tells someone he is talking to on the phone to keep quiet about the location of Air Force One and the fact that the plane is airborne. (North American Aerospace Defense Command 9/11/2001) Air Force One took off from Sarasota-Bradenton International Airport in Florida with President 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) Personnel at NEADS, however, only learned it was airborne about half an hour later (see 10:26 a.m. September 11, 2001). (North American Aerospace Defense Command 9/11/2001) A member of staff at NEADS, whose identity is unstated, is on the phone with someone whose identity is also unstated. He tells them, “If anybody calls, you get a phone call, anything, you pass [on] no information as to where Air Force One is and [the fact] that it’s airborne.” The person on the phone acknowledges the instruction, saying, “Copy.” A second member of staff at NEADS jokes, “I don’t know where he [i.e. Air Force One] is anyway” and laughs. The person on the phone then says he “didn’t know he [i.e. Air Force One] was airborne until you told me.” (North American Aerospace Defense Command 9/11/2001) It is unclear why the NEADS staffer wants details about Air Force One kept quiet. Some NEADS personnel have already discussed the plane and the need to provide fighter jets to escort it among themselves. (North American Aerospace Defense Command 9/11/2001) And an ID technician at NEADS talked about the location of the plane and its possible destination over the phone with someone at NORAD’s Southeast Air Defense Sector (SEADS) (see (10:45 a.m.) September 11, 2001). (North American Aerospace Defense Command 9/11/2001) A few minutes later, the member of staff at NEADS will again assert the need to keep quiet about what is happening this morning. At around 11:01 a.m., they will tell someone they are talking to on the phone, apparently the same person as before, “If you get phone calls from anybody on anything that’s going on, don’t forget: you direct them to public affairs or the MCC.” (The MCC is Major Kevin Nasypany, the NEADS mission crew commander.) The person on the phone will acknowledge the instruction, saying, “Copy.” (North American Aerospace Defense Command 9/11/2001)

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

President Bush (center, bending) and others look out  the windows of Air Force One as their fighter escort arrives.President Bush (center, bending) and others look out the windows of Air Force One as their fighter escort arrives. [Source: White House]President Bush, his entourage, and reporters accompanying them on board Air Force One notice fighter jets escorting their plane for the first time. Air Force One is currently flying westward over Mississippi, toward Barksdale Air Force Base in Louisiana. (Keen and Carney 9/11/2001; Sammon 2002, pp. 109; Kohn 9/11/2002) The White House requested a fighter escort for it (see 9:59 a.m. September 11, 2001) and the Secret Service asked Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, to provide that escort. (Code One Magazine 1/2002; 9/11 Commission 7/24/2004, pp. 38; Spencer 2008, pp. 255)
Passengers Notice Fighters - Now, air traffic control radios Colonel Mark Tillman, the pilot of Air Force One, and notifies him, “[Y]ou’ve got two F-16s at about your—say, your 10 o’clock position.” (Kohn 9/11/2002; Spencer 2008, pp. 255) Reporters on board notice a fighter flying alongside the plane’s right wing, and then spot another one alongside its left wing. (Keen and Carney 9/11/2001) According to a photographer on the plane, these jets are “so close that we could see the pilot’s head.” (BBC 9/1/2002) Bush also notices the fighters. (Sammon 2002, pp. 109) White House Communications Director Dan Bartlett will later recall: “The staff, and the president and us, were filed out along the outside hallway of his presidential cabin there and looking out the windows. And the president gives them a signal of salute, and the pilot kind of tips his wing, and fades off and backs into formation.” (Kohn 9/11/2002)
Fighters Maybe Arrived Earlier, but Remained out of Sight - According to most accounts, the jets alongside Air Force One belong to the 147th Fighter Wing of the Texas Air National Guard. (Kohn 9/11/2002; Filson 2003, pp. 87; Martin 7/4/2004; Rosenfeld and Gross 2007, pp. 40; Spencer 2008, pp. 255) But a few accounts will indicate they belong to a unit of the Florida Air National Guard in Jacksonville (see (10:00 a.m.) September 11, 2001). (US Department of Defense 9/2001; Langley 12/16/2001) Four 147th Fighter Wing jets have been directed toward the president’s plane to accompany it (see (After 9:56 a.m.) September 11, 2001). (Filson 2003, pp. 87; Rosenfeld and Gross 2007, pp. 40) But according to Sarasota Magazine, Air Force One is “currently being escorted by six jet fighters.” (Plunket 11/2001) Fifteen minutes earlier, at 11:14 a.m., an official, whose identity is unstated but who is not a member of the White House staff, told the reporters on Air Force One that the plane already had plenty of military escort, but the fighters were not visible at that time, presumably meaning they were escorting the plane from a distance. (Keen and Carney 9/11/2001)
Jets Protecting '80-Mile Bubble' around Air Force One - The two jets seen by the passengers on Air Force One are reportedly being flown by pilots Shane Brotherton and Randy Roberts of the 147th Fighter Wing. Roberts will later recall, “We were trying to keep an 80-mile bubble… around Air Force One, and we’d investigate anything that was within 80 miles.” (Kohn 9/11/2002; Spencer 2008, pp. 255) The 147th Fighter Wing jets will accompany Air Force One to Barksdale Air Force Base, then on to Offutt Air Force Base, Nebraska, and finally to Andrews Air Force Base, near Washington, DC. (Filson 2003, pp. 87-88; Cousins 7/9/2005)

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

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

Major General Paul Weaver, director of the Air National Guard, provides reporters with details of the 9/11 attacks and the US military’s response to the hijackings. Speaking at the Pentagon, Weaver gives reporters a detailed account of what happened on September 11. He says Air National Guard planes responded to the hijackings on orders from NORAD’s Northeast Air Defense Sector (NEADS), which was alerted to the hijackings by the Federal Aviation Administration (FAA).
Fighters Took Off Too Late to Catch Flight 175 - Weaver says that at 8:53 a.m., seven minutes after Flight 11 crashed into the North Tower of the World Trade Center (see 8:46 a.m. September 11, 2001), two F-15 fighter jets took off from Otis Air National Guard Base in Cape Cod, Massachusetts, in pursuit of Flight 175, the second plane to be hijacked (see 8:46 a.m. September 11, 2001 and 8:53 a.m. September 11, 2001). However, Weaver says, the FAA had only told NEADS that “there was an airplane that had a problem,” and at that time it was unclear if Flight 175 had been hijacked. He says that although the fighters flew at over 500 miles per hour, they were unable to catch up with Flight 175 before it hit the South Tower of the WTC at 9:03 a.m. (see 9:03 a.m. September 11, 2001).
More Fighters Were Launched Just before Pentagon Was Hit - Weaver says Flight 77, the third aircraft to be hijacked, flew west for 45 minutes and then turned east, and its transponder was turned off. He does not claim that the military received notice that it had been hijacked, but says NEADS scrambled F-16 fighters that were on alert at Langley Air Force Base in Virginia at 9:35 a.m. (see 9:24 a.m. September 11, 2001 and (9:25 a.m.-9:30 a.m.) September 11, 2001). Two minutes later, at 9:37 a.m., the Pentagon was hit (see 9:37 a.m. September 11, 2001). The F-16s, he says, subsequently remained on patrol over the Pentagon.
No Fighters Took Off to Intercept Flight 93 - Weaver says no fighters were scrambled to chase after Flight 93, the fourth hijacked plane, which crashed in a field in Pennsylvania (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001). “There was no notification for us to launch airplanes,” he tells the reporters. “We weren’t even close.” (Whittle 9/14/2001; Farmer 2009, pp. 244) (However, also on this day, Deputy Defense Secretary Paul Wolfowitz contradicts Weaver’s claim. He tells PBS’s NewsHour, “[W]e were already tracking in on that plane that crashed in Pennsylvania,” and adds, “[T]he Air Force was in a position to do so [i.e. shoot Flight 93 down] if we had had to.” (Wolfowitz 9/14/2001; Farmer 2009, pp. 245) ) Weaver says that even if fighters had caught up with the hijacked planes, they may have been unable to stop them reaching their targets. “You’re not going to get an American pilot shooting down an American airliner,” he says. “We don’t have permission to do that.” According to Weaver, only the president can issue an order to shoot down an American airliner. (Whittle 9/14/2001)
Weaver's Account Is the 'Most Accurate' Prior to the 9/11 Commission's Investigation - The account he gives to reporters today, according to John Farmer, the senior counsel to the 9/11 Commission, will be “the last public statement uttered by General Weaver on the subject and proved to be the most accurate account of events issued until the 9/11 Commission’s investigation.” (Farmer 2009, pp. 245) Apparently after Weaver issues his statement to the reporters, an Air Force spokesman, speaking on condition of anonymity, adds that no regular Air Force planes were scrambled during the 9/11 attacks, “because continental air defense is the mission of the Air National Guard.” He says regular Air Force fighters “have air superiority as their mission,” which means they train “to deploy somewhere where we are engaged in hostile action and secure the skies.” These fighters, according to the spokesman, “ordinarily are not ready to fly on short notice and their pilots are not on standby to defend the United States.” (Whittle 9/14/2001)
Pentagon Has Been Slow to Answer Questions about Response to Hijackings - The Washington Post will comment, “Questions about the time it took US military planes to respond to the threat of several hijacked aircraft speeding toward the nation’s financial and military centers have dogged the Pentagon since the attacks.” It will add, “Top Pentagon officials have been slow to respond to press inquiries for a timeline that would establish the exact times that civil aviation authorities became aware of the hijackings, when US military commanders were notified, and when US fighter jets took to the air.” (Graham 9/15/2001) The previous day, Air Force General Richard Myers was questioned about the military’s response to the attacks before the Senate Armed Services Committee, but his answers were vague and confused (see September 13, 2001). (US Congress 9/13/2001; Farmer 2009, pp. 241-242) NORAD will release its own timeline of the events of September 11 and its response to the hijackings on September 18 (see September 18, 2001). (North American Aerospace Defense Command 9/18/2001; 9/11 Commission 7/29/2004)

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

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

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

Matthys Levy.Matthys Levy. [Source: PBS]A report is made publicly available, which the Engineering News-Record calls the “most comprehensive study yet on the destruction of the World Trade Center.” The study was commissioned by WTC leaseholder Silverstein Properties Inc. to support a $7 billion insurance claim, and conducted by a team of engineers from several leading firms, including Weidlinger Associates, LZA Technology/Thornton-Tomasetti, and ARUPFire. It is intended to build on a previous study sponsored by FEMA (see May 1, 2002). The report’s findings are based on an analysis of original structural drawings, thousands of photos, and dozens of videos. Investigators used fire evaluation techniques and powerful computer software to simulate the condition of each tower at critical times between the planes’ impacts and the towers’ collapses. The earlier FEMA investigators had no access to such computer modeling. Matthys Levy, the chairman of Weidlinger Associates and one of the engineers on the study team, says, “The buildings had tremendous reserve capacity and that was reflected in all of the elements we analyzed. In fact, because there were so much excess capacity, the columns even in the impact floors did not buckle immediately, but failed as the result of the fire.” The report states that failure of the WTC’s steel floor supports (“trusses”) did not contribute to the collapses. Instead, the collapses were caused by the failure of steel structural columns that were either destroyed when the planes hit or lost fireproofing, leaving them vulnerable to the weakening effects of the ensuing fires. It says that debris and dust distributed by the plane crashes inhibited the fires, such that the average air temperatures on the impact floors were between 400 and 700°C (750-1,300°F): significantly lower than those associated with typical “fully developed” office fires. However, says Matthys Levy, “By the time the temperature inside the buildings reached 400 degrees, the steel would have lost approximately 50% of its strength. Eventually, gravity took over and the towers began to fall.” Then, according to the analysis led by researchers from LZA Technology/Thornton-Tomasetti, “Once collapse initiated in each tower, essentially all of the interior structure of the tower fell straight down with floors pancaking on top of one another. The network of perimeter steel columns and spandrels acted like a chute to funnel the interior contents into the tower footprint.” According to the computer simulations, the damage to the South Tower’s steel core columns was so severe that the tower should have collapsed immediately after the plane hit. Civil engineer John Osteraas says this incorrect result casts doubt upon some of the study’s predictions. The report concludes that the collapse of the South Tower did not cause or contribute to the subsequent collapse of the North Tower, thus supporting Silverstein Properties’ claim that the terrorist attack represented two occurrences, entitling it to two $3.5 billion insurance policy limits. A separate study commissioned by the insurers contradicts this (see October 23, 2002). The Silverstein report apparently does not examine the collapse of WTC Building 7, a 47-story skyscraper that also collapsed on 9/11 (see (5:20 p.m.) September 11, 2001). It has been passed on to the National Institute of Standards and Technology (NIST), which is undertaking its own investigation of the WTC collapses (see August 21, 2002). (Glanz and Lipton 9/30/2002; McLeod 10/23/2002; Silverstein Properties, Inc. 10/23/2002 pdf file; Post 10/25/2002; Glanz and Lipton 10/29/2002; Post 11/4/2002; Misonzhnik 4/30/2003)

Shyam Sunder.Shyam Sunder. [Source: NIST]The National Institute of Standards and Technology (NIST) releases nearly 500 pages of documents, detailing the latest findings of its investigation of the WTC collapses on 9/11. These include its hypotheses for the collapse sequences of each of the Twin Towers; details of their analysis of interviews with nearly 1,200 building occupants, emergency responders, and victims’ relatives; and information from their analysis of the emergency response and evacuation procedures. Their investigation into the collapses is based upon an analysis of thousands of photos and videos, examination of many of the elements used to construct the towers, and computer-enhanced modeling of the plane impacts and the spreading of the fires. Their hypothesis is that the towers collapsed ultimately due to the fires they suffered: As the fires burned, the buildings’ steel core columns buckled and shortened. This shifted more load to the buildings’ perimeter columns, which were already affected by the heat of the fires, and caused them to give way under the increased stress. Investigators have conducted a test with a reconstructed section of the WTC floor, and found that the original fireproofing was sufficient to meet the New York City building code. They say that had a typical office fire occurred in the towers, without the structural damage and the loss of some fireproofing caused by the plane impacts, it is likely the buildings would have remained standing. Lead investigator Dr. Shyam Sunder says, “The buildings performed as they should have in the airplane impact and extreme fires to which they were subjected. There is nothing there that stands out as abnormal.” NIST’s theories of why the WTC buildings collapsed conflict with an earlier investigation by FEMA, which claimed the collapse of the North Tower had begun in its core, rather than its perimeter columns (see May 1, 2002). (National Institute of Standards and Technology 10/19/2004; Lipton 10/20/2004)

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

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