The specially modified C-135 nicknamed ‘Speckled Trout.’The specially modified C-135 nicknamed ‘Speckled Trout.’ [Source: United States Air Force]General Henry Shelton, the chairman of the Joint Chiefs of Staff, takes off to fly to Europe for a NATO conference, and will therefore be away from the US when the 9/11 terrorist attacks occur. [Giesemann, 2008, pp. 20, 22; Shelton, Levinson, and McConnell, 2010, pp. 430-433] Shelton is scheduled to attend a meeting of the Military Committee—NATO’s highest military authority—in Budapest, Hungary, on September 12, to discuss the situation in the Balkans, the European Security and Defense Identity, and NATO’s new force structure. On his return journey, he is set to stop in London, Britain, to be knighted by the Queen. [North Atlantic Treaty Organization, 9/10/2001; North Atlantic Treaty Organization, 9/11/2001; Shelton, Levinson, and McConnell, 2010, pp. 430] Shelton takes off from Andrews Air Force Base, just outside Washington, DC, on a specially modified C-135 (the military version of a Boeing 707) nicknamed “Speckled Trout.” Normally he flies on a VIP Boeing 757 often used by the vice president, but that aircraft is presently unavailable, so he is flying instead on the C-135, which is usually reserved for the Air Force chief of staff. Those accompanying Shelton on the flight include his wife, Carolyn; his executive assistant, Colonel Doug Lute; his aides, Master Sergeant Mark Jones and Lieutenant Commander Suzanne Giesemann; and his personal security agent, Chief Warrant Officer Marshall McCants. [Giesemann, 2008, pp. 20-22; Shelton, Levinson, and McConnell, 2010, pp. 431, 434] When Shelton is out of the country, General Richard Myers, the vice chairman of the Joint Chiefs of Staff, is designated by law as acting chairman of the Joint Chiefs of Staff in his place. Shelton will later recall, “Until I crossed back into United States airspace, all the decisions would be [Myers’s] to make, in conjunction with Secretary [of Defense Donald] Rumsfeld and the president.” [Myers, 2009, pp. 10; Shelton, Levinson, and McConnell, 2010, pp. 432] After learning of the attacks in New York, Shelton will give the order for his plane to return to the US (see (8:50 a.m.-10:00 a.m.) September 11, 2001). [Giesemann, 2008, pp. 22-23; Shelton, Levinson, and McConnell, 2010, pp. 431] However, the plane will repeatedly be denied permission to enter US airspace (see (After 9:45 a.m.) September 11, 2001) and will only land back in the US at 4:40 p.m. (see 4:40 p.m. September 11, 2001). Shelton will only arrive at the National Military Command Center at the Pentagon an hour after that (see 5:40 p.m. September 11, 2001).

Thomas White.Thomas White. [Source: US Department of Defense]Secretary of Defense Donald Rumsfeld hosts a breakfast meeting in his private dining room at the Pentagon. [Associated Press, 9/12/2001; US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] The meeting, which is attended by several members of Congress, is intended to discuss the Department of Defense’s Quadrennial Defense Review. As well as the secretary of defense, others in attendance include Rumsfeld’s senior military assistant, Navy Vice Admiral Edmund Giambastiani Jr.; Deputy Defense Secretary Paul Wolfowitz; Pete Geren, a special assistant to Rumsfeld; and Representatives John Mica (R-FL), Mark Steven Kirk (R-IL), Mac Thornberry (R-TX), Roger Wicker (R-MS), Robin Hayes (R-NC), Doug Bereuter (R-NE), John Hostettler (R-IN), Kay Granger (R-TX), John Shimkus (R-IL), Randy “Duke” Cunningham (R-CA), and Christopher Cox (R-CA). [Powell Moore, 9/10/2001 pdf file; Fort Worth Star-Telegram, 9/14/2001; Federal Computer Week, 3/31/2003; Vanity Fair, 5/9/2003; Powell Moore, 9/19/2003 pdf file; US Department of Defense, 9/10/2004; American Forces Press Service, 9/8/2006] Secretary of the Army Thomas White, who is at the meeting, appears to say it is also attended by numerous key military figures, later telling PBS: “Don Rumsfeld had a breakfast, and virtually every one of the senior officials of the Department of Defense—service chiefs, secretary, deputy, everybody, chairman of the Joint Chiefs of Staff. And as that breakfast was breaking up, the first plane had hit the World Trade tower.” [PBS Frontline, 10/26/2004; PBS, 10/26/2004] By “chairman of the Joint Chiefs of Staff,” White presumably means Richard Myers, who is the acting chairman on this day, in place of Henry Shelton who is out of the country (see 7:15 a.m. September 11, 2001). [American Forces Press Service, 9/8/2006] During the course of the meeting Rumsfeld predicts that some kind of “shocking” world event will occur in the near future (see (Before 8:46 a.m.) September 11, 2001). Most accounts suggest the meeting is adjourned soon after the time the first World Trade Center tower is hit, presumably around 8:50 a.m., though one report says it ends at about 9:00 a.m. Just prior to the meeting ending, Rumsfeld is handed a note informing him of the crash (see Shortly After 8:46 a.m. September 11, 2001). Giambastiani also sees this note. Whether the other people in attendance are notified of the crash at this time is unknown. [US Department of Defense, 12/5/2001; US Department of Defense, 8/12/2002; PBS, 10/26/2004; American Forces Press Service, 9/8/2006] White will later recall, “We all went on with the day’s business,” after leaving the meeting. White heads off to give a speech at the nearby Army Navy Country Club. [PBS Frontline, 10/26/2004] Rumsfeld, Wolfowitz, and Giambastiani return to their offices. [Vanity Fair, 5/9/2003; American Forces Press Service, 9/8/2006] The members of Congress leave the building. [Washington Post, 1/9/2002] If Myers is at the meeting, as White appears to say, he must head promptly to Capitol Hill, as he enters another meeting in the offices of Senator Max Cleland (D-GA) before the time when the second WTC tower is hit (see Shortly Before 9:00 a.m. September 11, 2001).

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.

John Mica.John Mica. [Source: Publicity photo]Defense Secretary Donald Rumsfeld, Deputy Defense Secretary Paul Wolfowitz, Representatives Christopher Cox (R-CA) and John Mica (R-FL), and numerous others are meeting in Rumsfeld’s private Pentagon dining room, discussing missile defense (see (8:00 a.m.-8:50 a.m.) September 11, 2001). Rumsfeld later recalls, “I had said at an eight o’clock breakfast that sometime in the next two, four, six, eight, ten, twelve months there would be an event that would occur in the world that would be sufficiently shocking that it would remind people again how important it is to have a strong healthy Defense Department that contributes to—that underpins peace and stability in our world.” [US Department of Defense, 12/5/2001] Wolfowitz recalls, “And we commented to them that based on what Rumsfeld and I had both seen and worked on the Ballistic Missile Threat Commission, that we were probably in for some nasty surprises over the next ten years.” [Vanity Fair, 5/9/2003] According to Mica, “the subject of the conversation Donald Rumsfeld was interested in was, the military had been downsized during the ‘90s since the fall of the Berlin Wall. And what we were going to do about [the] situation if we had another—the word [Rumsfeld] used was ‘incident.‘… And he was trying to make certain that we were prepared for something that we might not expect.” [US Congress. House. Oversight and Government Reform Committee, 8/1/2007] There are confused accounts that Rumsfeld says, “I’ve been around the block a few times. There will be another event,” just before the Pentagon is hit by Flight 77 (see (Before 9:37 a.m.) September 11, 2001), but such comments may have been made around this time instead. Shortly afterwards, someone walks in with a note informing Rumsfeld that a plane has just hit the WTC (see Shortly After 8:46 a.m. September 11, 2001). [US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] Mica later comments, “[L]ittle did we know that within a few minutes of the end of our conversation and actually at the end of our breakfast, that our world would change and that incident that we talked about would be happening.” [US Department of Defense, 9/10/2004]

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

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. [New York Times, 9/12/2001; State Government News, 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; State Government News, 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.” [New York Times, 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. [Stateline (.org), 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. [Stateline (.org), 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. [State Government News, 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. [Stateline (.org), 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. [New York Times, 9/12/2001; State Government News, 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.” [Stateline (.org), 9/13/2001; State Government News, 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.

Larry Di Rita.Larry Di Rita. [Source: US Department of Defense]Larry Di Rita, a special assistant to Defense Secretary Donald Rumsfeld, has sent a note to Rumsfeld to inform him of the first plane hitting the World Trade Center. Although some initial reports suggest the WTC may have been hit by just a small plane, according to Victoria Clarke, the assistant secretary of defense for public affairs, “Even in the accidental crash scenario, the military might be involved in some way. Rumsfeld needed to know.” Rumsfeld, who is currently hosting a breakfast meeting with several members of Congress (see (8:00 a.m.-8:50 a.m.) September 11, 2001), later acknowledges having received this note. Yet apparently he does nothing in response. He recalls, “Everyone assumed it was an accident, the way it was described.” He says only that “we adjourned the meeting, and I went in to get my CIA briefing.” [US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004; Clarke, 2006, pp. 217-218; Vogel, 2007, pp. 428]

[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; New York Times, 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).

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

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; Dayton Daily News, 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). [McClatchy Newspapers, 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. [Dayton Daily News, 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; Springfield News-Sun, 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; Politico Magazine, 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. [Cape Cod Times, 9/12/2001; Cape Cod Times, 9/12/2001] On a typical day, it has about a dozen pilots on duty. [Cape Cod Times, 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. [Boston Globe, 9/15/2001; Cape Cod Times, 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).

Air Force General Richard Myers, vice chairman of the Joint Chiefs of Staff, and acting chairman on 9/11. [Source: NORAD]According to his own account, Air Force General Richard Myers, the vice chairman of the Joint Chiefs of Staff, sees reports of the first WTC crash on television. Myers is acting chairman of the US military during the 9/11 crisis because Chairman of the Joint Chiefs of Staff Army General Henry Shelton is flying across the Atlantic for a NATO meeting in Europe. [ABC News, 9/11/2002; American Forces Press Service, 9/8/2006] Myers has a 9 o’clock appointment with Senator Max Cleland (D-GA) in one of the Senate office buildings. He is heading into this meeting and sees a television in Cleland’s outer office showing the burning North Tower, with the commentator suggesting it has been hit by an airplane. [MSNBC, 9/11/2002] Myers later recalls, “They thought it was a small plane or something like that.” [Armed Forces Radio And Television Service, 10/17/2001; American Forces Press Service, 10/23/2001] He says, “And we’re standing around saying, ‘What in the world happened?’ I remember the day being beautiful. I said, ‘How could a pilot be that stupid, to hit a tower? I mean, what’—but then you think, ‘Well, whatever.’” So he goes ahead and walks into the meeting, and is with Cleland at the time the second tower is hit (see (Shortly After 9:03 a.m.) September 11, 2001). [Council on Foreign Relations, 6/29/2006] On several occasions, Cleland will confirm that Myers had this meeting with him. [US Congress, 9/13/2001; CNN, 11/20/2001; Atlanta Journal-Constitution, 6/16/2003] But counterterrorism “tsar” Richard Clarke seems to contradict this account. He claims that, when he joins a video teleconference shortly after arriving at the White House, he sees Myers on screen, indicating that Myers is at the Pentagon rather than with Cleland (see (9:10 a.m.) September 11, 2001).

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. [Dover Post, 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.” [Dover Post, 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. [Syracuse University Magazine, 12/2001; Air Force Print News, 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.” [Dover Post, 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. [Syracuse University Magazine, 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. [Dover Post, 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.” [Midland Reporter-Telegram, 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). [Air Force Print News, 9/11/2003; Air Force Magazine, 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).

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. [New York Times, 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.” [New York Times, 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). [New Jersey Star-Ledger, 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. [Fire Engineering, 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.

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

[Source: Risk Assessment Network + Exchange]Secretary of Defense Donald Rumsfeld goes ahead with his daily intelligence briefing in his office at the Pentagon, even though Denny Watson, his CIA briefer, urges him to cancel it and respond to the terrorist attacks. [Rumsfeld, 2011, pp. 335; Priess, 2016, pp. 244] Rumsfeld has just been in a meeting in his private dining room that was attended by several members of Congress (see (8:00 a.m.-8:50 a.m.) September 11, 2001). During it, he was informed that a plane had crashed into the World Trade Center (see Shortly After 8:46 a.m. September 11, 2001). [Associated Press, 9/12/2001; US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004] He assumed the crash was an accident. [Vogel, 2007, pp. 428; Rumsfeld, 2011, pp. 335]
Rumsfeld Went to His Office for His Intelligence Briefing - After the meeting ended, apparently around 9:00 a.m., he returned to his office to receive his intelligence briefing. [Historical Office, Office of the Secretary of Defense, 7/18/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 37] Rumsfeld receives an intelligence briefing from Watson each morning, similar to the intelligence briefing provided to the president each day. The briefings usually last at least half an hour. [Rumsfeld, 2011, pp. 335; Priess, 2016, pp. 243] The briefing today is scheduled to run from 9:00 a.m. to 9:30 a.m. [US Department of Defense, 8/12/2002]
CIA Briefer Learned of the Crashes from TV - Watson, meanwhile, recently arrived at the Pentagon and learned about the crashes at the WTC. After she entered the building, she noticed people staring at a television, which showed the North Tower burning after being hit by a plane. She then went to the anteroom of Rumsfeld’s office, where she saw the second hijacked plane crashing into the WTC live on television (see 9:03 a.m. September 11, 2001). She immediately called the operations center at CIA headquarters to see if she could find out more about what was happening. She was told only that there were 50 planes still airborne that were unaccounted for.
Rumsfeld Refuses to Cancel the Briefing - Rumsfeld then calls Watson into his office. Assuming the briefing will be suspended due to what has happened in New York, the CIA analyst hasn’t even opened her briefcase to pull out her copy of the President’s Daily Brief (PDB). “Sir, you just need to cancel this,” she says to Rumsfeld as she enters the office. “You’ve got more important things to do,” she adds. Rumsfeld, however, wants to go ahead with the briefing. “No, no, we’re going to do this,” he says. Watson then sits down and tells Rumsfeld what she learned from the CIA’s operations center, but the secretary of defense simply nods his head and starts flipping through the PDB. [Priess, 2016, pp. 244] The PDB apparently contains no remarkable information today. “As we reviewed the threat reports from around the world, September 11 seemed to be no more or less different than any other day,” Rumsfeld will later comment. [Rumsfeld, 2011, pp. 336]
Rumsfeld Will Be Receiving the Briefing When the Pentagon Is Hit - Vice Admiral Edmund Giambastiani Jr., Rumsfeld’s senior military assistant, will come into the office around this time and tell the secretary of defense about the second crash at the WTC (see (Shortly After 9:03 a.m.) September 11, 2001). [Historical Office, Office of the Secretary of Defense, 7/18/2002 pdf file; US Department of Defense, 8/12/2002] Two of Rumsfeld’s aides will also come to the office and, like Watson, try, unsuccessfully, to persuade Rumsfeld to cancel his schedule so he can respond to the attacks (see a904rumsfeldrefuses). [Clarke, 2006, pp. 218-219; Priess, 2016, pp. 244] Rumsfeld will be in his office with Watson, still receiving his intelligence briefing, at 9:37 a.m., when the Pentagon is attacked (see 9:37 a.m. September 11, 2001).

National Security Adviser Condoleezza Rice tries to gather together the principals of the National Security Council (NSC), but is unable to get in touch with key officials. Rice realized the US was under terrorist attack during a staff meeting, when her assistant informed her of the second plane striking the World Trade Center (see (9:04 a.m.) September 11, 2001). She had then headed to the White House Situation Room’s operations center. [Newsweek, 12/30/2001; Bumiller, 2007, pp. xii] Here she intends to assemble the principals of the NSC for a crisis meeting. [O, the Oprah Magazine, 2/1/2002] Along with the national security adviser, the principal members of the NSC are the president, the vice president, the secretary of state, the secretary of the treasury, and the secretary of defense; additionally, the CIA director and the chairman of the Joint Chiefs of Staff are statutory advisers to the NSC. [US President, 2/13/2001; Felix, 2002, pp. 226] However, Rice remembers that Secretary of State Colin Powell is currently away in Peru (see (8:30 a.m.) September 11, 2001). [MSNBC, 9/11/2002] Treasury Secretary Paul O’Neill is away in Japan. [US Department of the Treasury, 11/29/2001; US Department of the Treasury, 1/23/2002] And Chairman of the Joint Chiefs of Staff Henry Shelton is on his way to Europe for a NATO meeting there. [CNN, 10/1/2001] Rice tries calling Defense Secretary Donald Rumsfeld, who is in his office at the Pentagon (see (Shortly After 9:03 a.m.) September 11, 2001), but cannot reach him. [PBS Frontline, 7/12/2002; Clarke, 2006, pp. 218-219; Cockburn, 2007, pp. 1] She is also unable to get a call through to CIA Director George Tenet. [Bumiller, 2007, pp. xii] (Tenet will later claim that, around this time, he is having trouble using his secure phone while being driven out to CIA headquarters (see (8:55 a.m.-9:15 a.m.) September 11, 2001). [Tenet, 2007, pp. 161-162] ) Also around this time, in the Secure Video Conferencing Center just off the main floor of the Situation Room, counterterrorism “tsar” Richard Clarke is trying to convene a video teleconference with other top officials (see (9:10 a.m.) September 11, 2001).

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

Laura Bush, the president’s wife, leaves the White House in her limousine, on her way to Capitol Hill where she is scheduled to testify before a Congressional committee, but she is unaware that a second plane has crashed into the World Trade Center. [Us Weekly, 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. [CNN, 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.” [USA Today, 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).

Around this time, according to his own account, counterterrorism “tsar” Richard Clarke reaches the Secure Video Conferencing Center just off the main floor of the Situation Room in the West Wing of the White House. From there, he directs the response to the 9/11 attacks and stays in contact with other top officials through video links. Clarke claims that on video he can see Defense Secretary Donald Rumsfeld, CIA Director George Tenet, FBI Director Robert Mueller, FAA Administrator Jane Garvey, Deputy Attorney General Larry Thompson (filling in for the traveling Attorney General John Ashcroft), Deputy Secretary of State Richard Armitage (filling in for the traveling Secretary of State Colin Powell), and Vice Chairman of the Joint Chiefs of Staff Richard Myers (filling in for the traveling Chairman Henry Shelton). National Security Adviser Condoleezza Rice is with Clarke, but she lets him run the crisis response, deferring to his longer experience on terrorism matters. Clarke is also told by an aide, “We’re on the line with NORAD, on an air threat conference call.” [Clarke, 2004, pp. 2-4; Australian, 3/27/2004] According to the 9/11 Commission, logs indicate that Clarke’s video teleconference only begins at 9:25 a.m. (see 9:25 a.m. September 11, 2001), which is later than Clarke suggests, and CIA and FAA representatives only join it at 9:40 a.m. [9/11 Commission, 7/24/2004, pp. 36 and 462] Other accounts claim that, rather than being involved in Clarke’s teleconference at this time, Donald Rumsfeld is still in his office waiting for his intelligence briefing (see (Shortly After 9:03 a.m.) September 11, 2001), and Richard Myers is in a meeting on Capitol Hill (see (Shortly After 9:03 a.m.) September 11, 2001). [Armed Forces Radio And Television Service, 10/17/2001; Clarke, 2006, pp. 218-219] The 9/11 Commission claims that, “While important,” Clarke’s conference has “no immediate effect on the emergency defense efforts.” [9/11 Commission, 6/17/2004] Yet, as the Washington Post puts it, “everyone seems to agree” Clarke is the chief crisis manager on 9/11. [Washington Post, 3/28/2004] Even Clarke’s later opponent, National Security Adviser Rice, calls him 9/11’s “crisis management guy.” [United Press International, 4/9/2004] The conference is where the government’s emergency defense efforts are concentrated.

The US Strategic Command (Stratcom) orders that its Global Guardian exercise be put on pause at this time, according to a 2006 article in The Bombardier, the newspaper for Barksdale Air Force Base, Louisiana. [Bombardier, 9/8/2006 pdf file] Global Guardian is an annual exercise sponsored by Stratcom, which has its headquarters at Offutt Air Force Base, Nebraska.

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

Noelia Rodríguez.Noelia Rodríguez. [Source: Harvard University]Laura Bush, the president’s wife, is told that a second plane has crashed into the World Trade Center and realizes this is a terrorist attack while she is being driven from the White House to Capitol Hill, where she is scheduled to testify before a Congressional committee. [Us Weekly, 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. [USA Today, 9/10/2001; CNN, 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).

Mike Fenzel.Mike Fenzel. [Source: Wall Street Journal]According to counterterrorism “tsar” Richard Clarke, around this time, National Security Adviser Condoleezza Rice says she is going down to the Presidential Emergency Operations Center (PEOC) below the White House to be with Vice President Dick Cheney. Clarke is currently convening a video teleconference with top officials from the Secure Video Conferencing Center, just off the main floor of the Situation Room (see (9:10 a.m.) September 11, 2001). Rice has just walked in with her deputy, Stephen Hadley. Clarke asks her, “Do you want to chair this as a principals meeting?” [Clarke, 2004, pp. 2-4] (A “principals meeting” includes the principals of the National Security Council, but not the president. [Bumiller, 2007, pp. 141] ) Rice declines, allowing Clarke to run the conference. Clarke will recall that Rice says to him: “You’re going to need some decisions quickly. I’m going to the PEOC to be with the vice president. Tell us what you need.” Clarke replies, “What I need is an open line to Cheney and you.” Clarke then turns to his White House Fellow, Army Major Mike Fenzel, and instructs him to “go with Condi to the PEOC and open a secure line to me. I’ll relay the decisions we need to you.” [Clarke, 2004, pp. 3-4] However, according to her own later recollections, Rice does not head down from the Situation Room to the PEOC until later, at some time shortly after the Pentagon is hit (see (9:45 a.m.) September 11, 2001).

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. [St. Petersburg Times, 7/4/2004; Politico Magazine, 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.” [Washington Times, 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). [Studies in Intelligence, 9/2006 pdf file; Politico Magazine, 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.” [Politico Magazine, 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. [Politico Magazine, 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. [St. Petersburg Times, 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.” [University Press, 9/18/2003] Bush “was courageously insistent about remaining on the ground to make a statement to the people of America,” Brogan will comment. [South Florida Sun-Sentinel, 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]

Ted Olson.
Ted Olson. [Source: US Department of Justice]Ted Olson, the solicitor general of the United States, calls the Department of Justice command center to pass on information he has received in a call from his wife, who is a passenger on Flight 77, and ask for someone there to come to his office. [9/11 Commission, 8/26/2004, pp. 32, 95] His wife, Barbara Olson, has just called him, and was able to say her plane had been hijacked and give him details of the hijacking before the call got cut off (see (Between 9:15 a.m. and 9:25 a.m.) September 11, 2001).
Olson Is Unable to Reach Attorney General Ashcroft - After the call from his wife has ended, Ted Olson tries to call Attorney General John Ashcroft on a direct line he has to Ashcroft, but receives no answer. He then calls the Department of Justice command center to pass on the details of his wife’s call. He contacts the command center, he will later say, because he wants to give Barbara Olson’s information “to someone who could possibly do something.” [Federal Bureau of Investigation, 9/11/2001; Newsweek, 9/28/2001] “I mainly wanted them know there was another hijacked plane out there,” he will comment. [Fox News, 9/14/2001]
Olson Is Told Command Center Personnel Are Unaware of the Hijacking - He tells the person who answers the call that his wife’s plane has been hijacked and gives them the number of the flight. [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 8/26/2004, pp. 32] “I want you to know there’s another plane that’s been hijacked; my wife is on it,” he says. [Newsweek, 9/28/2001] He adds that his wife is able to communicate from the plane, even though her call to him got cut off. [CNN, 9/14/2001] “They just absorbed the information,” he will recall, adding, “I expected them to pass the information on to the appropriate people.” [Fox News, 9/14/2001] He is told that officials in the command center know nothing about the hijacking of Flight 77. [Washington Post, 9/12/2001]
Olson Wants a Security Officer to Come to His Office - Ted Olson also requests that a security officer from the command center come to his office. According to Helen Voss, his special assistant, he does this because he thinks the security officer will be able to talk to Barbara Olson if she calls him again. [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 8/26/2004, pp. 32] But Ted Olson will comment that at this time, “I didn’t know that I was going to get another call [from Barbara Olson].” He is told someone will be sent to his office right away. [Fox News, 9/14/2001] Shortly after he contacts the command center, Barbara Olson will call him a second time and provide more details about the hijacking of Flight 77 (see (Between 9:20 a.m. and 9:30 a.m.) September 11, 2001). [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 7/24/2004, pp. 9; 9/11 Commission, 8/26/2004, pp. 32]
Security Officer Goes to Olson's Office - Meanwhile, Allen Ferber, a security officer in the command center, is told to go to Ted Olson’s office. He is told by the watch officer that the solicitor general’s wife is on a plane that has been hijacked, the hijackers were armed with knives, and the passengers have been moved to the back of the plane. He will arrive at Ted Olson’s office after Barbara Olson’s second call from Flight 77 has ended. He will stay there, watching the television coverage of the crashes at the World Trade Center with Ted Olson, for about 10 minutes. He will leave the office before the attack on the Pentagon is reported on television (see 9:39 a.m.-9:44 a.m. September 11, 2001) but return to it after the attack starts being reported (see (Shortly After 9:37 a.m.) September 11, 2001).

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. [US News and World Report, 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).

The telephone Ted Olson used when he spoke to his wife, who called him from Flight 77.The telephone Ted Olson used when he spoke to his wife, who called him from Flight 77. [Source: US Department of Justice]Barbara Olson, a passenger on Flight 77, talks over the phone with her husband, Ted Olson, the solicitor general of the United States, for a second time and is able to give him additional details of the hijacking of her plane before the call gets cut off. She has just called him at his office at the Department of Justice in Washington, DC, and was able to say her plane had been hijacked and give him details of the hijacking before the call got disconnected (see (Between 9:15 a.m. and 9:25 a.m.) September 11, 2001). [CNN, 9/14/2001; 9/11 Commission, 7/24/2004, pp. 9] Since then, Ted Olson has called the Department of Justice command center and passed on the information she provided (see (Between 9:17 a.m. and 9:29 a.m.) September 11, 2001). [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 8/26/2004, pp. 32]
Secretary Answers the Call - Shortly after making her first call to him, Barbara Olson calls Ted Olson again. [9/11 Commission, 7/24/2004, pp. 9] The call is initially answered by Lori Keyton, a secretary in Ted Olson’s office. When Keyton picks up the phone, Barbara Olson says, “It’s Barbara.” Keyton says she will put her through to her husband. [Federal Bureau of Investigation, 9/11/2001] Ted Olson is told his wife is on the phone again and the call is put through to him.
Barbara Olson Says Her Plane Has Been Circling Around - Barbara Olson then gives her husband additional information about the hijacking of Flight 77. She says the pilot announced that the plane had been hijacked. Ted Olson asks if she has any idea of her plane’s location. [Federal Bureau of Investigation, 9/11/2001; CNN, 9/14/2001; 9/11 Commission, 7/24/2004, pp. 9; 9/11 Commission, 8/26/2004, pp. 32] She says the plane was hijacked shortly after takeoff and has been circling around for a while. [CNN, 9/14/2001; Fox News, 9/14/2001] (However, according to the 9/11 Commission Report, Flight 77 was hijacked between around 8:51 a.m. and 8:54 a.m. (see 8:51 a.m.-8:54 a.m. September 11, 2001), more than 30 minutes after it took off (see (8:20 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 8] ) She says it is currently flying over some houses. After consulting another person on the plane, she says she thinks they are heading northeast.
Barbara Olson Asks What She Should Tell the Pilot - Ted Olson says two aircraft, besides Flight 77, were hijacked this morning and these planes subsequently crashed into the World Trade Center. Barbara Olson “absorbed the information,” the solicitor general will later recall. The couple then try to reassure each other. Ted Olson says, “It’s going to come out okay” and Barbara Olson tells him the same thing. She then says, “I love you.” Before the call ends, the couple “segued back and forth between expressions of feeling for one another and this effort to exchange information,” Ted Olson will recall. [Federal Bureau of Investigation, 9/11/2001; CNN, 9/14/2001; 9/11 Commission, 7/24/2004, pp. 9; 9/11 Commission, 8/26/2004, pp. 32] “We exchanged the feelings that a husband and wife who are extraordinarily close—as we are—those kind of sentiments,” he will say. [Fox News, 9/14/2001] The last thing Barbara Olson says is: “What shall I tell the pilot? What can I tell the pilot to do?” This implies that either the plane’s pilot or the co-pilot is at the back of the plane, where the hijackers moved the passengers, Ted Olson will note. [Washington Post, 9/12/2001; CNN, 9/14/2001]
Call Is Abruptly Cut Off - The call then ends abruptly, with the line suddenly going dead. It has lasted “two or three or four minutes,” Ted Olson will estimate. [Federal Bureau of Investigation, 9/11/2001; CNN, 9/14/2001; 9/11 Commission, 8/26/2004, pp. 32] Ted Olson will then return to watching the coverage of the attacks at the WTC on television. When he sees the reports about an attack at the Pentagon, he will immediately think his wife’s plane crashed there (see (Shortly After 9:37 a.m.) September 11, 2001). [Federal Bureau of Investigation, 9/11/2001; Federal Bureau of Investigation, 9/11/2001; Fox News, 9/14/2001]
Call Is Made Sometime between 9:20 a.m. and 9:30 a.m. - The exact time of Barbara Olson’s second call to her husband is unclear. A list compiled by the Department of Justice supposedly showing all of the calls made today from Flight 77 will include four “connected calls to unknown numbers” (see 9:15 a.m.-9:30 a.m. September 11, 2001) and the 9/11 Commission Report will determine that these include the two calls made by Barbara Olson. According to the information in the list, her second call must occur at 9:20 a.m., 9:25 a.m., or 9:30 a.m. and last for 4 minutes 34 seconds, 2 minutes 39 seconds, or 4 minutes 20 seconds. [9/11 Commission, 5/20/2004; 9/11 Commission, 7/24/2004, pp. 455; 9/11 Commission, 8/26/2004, pp. 94]
Call Is Made Directly to Ted Olson's Office - It is also unclear whether Barbara Olson makes this call using a cell phone or an Airfone. Keyton’s phone has no caller identification feature and so she is unable to determine what kind of phone Barbara Olson uses. [Federal Bureau of Investigation, 9/11/2001] But the Department of Justice will determine that all of the calls from Flight 77 were made using Airfones. [9/11 Commission, 5/20/2004] Barbara Olson makes the call by dialing “0,” apparently in an attempt to reach an operator, according to an FBI report. [Federal Bureau of Investigation, 9/20/2001] But Keyton will say that, unlike the first call, Barbara Olson’s second call to her husband is made directly to his office, rather than reaching it via an operator. [Federal Bureau of Investigation, 9/11/2001] And Mercy Lorenzo, the operator who connected Barbara Olson’s first call to Ted Olson’s office (see (Between 9:15 a.m. and 9:25 a.m.) September 11, 2001), will apparently mention dealing with only one call, not two, from Barbara Olson when she is interviewed by the FBI.

According to his own account, counterterrorism “tsar” Richard Clarke, started a video teleconference from the White House’s Secure Video Conferencing Center, next to the Situation Room, at around 9:10 a.m.(see (9:10 a.m.) September 11, 2001). However, the 9/11 Commission says that logs indicate this conference beginning 15 minutes later than this. Included in the conference are the FBI, the CIA, the FAA, the departments of State, Justice, and Defense, and the White House shelter. The FAA and CIA join at 9:40 a.m. The 9/11 Commission says, “It is not clear to us that the video teleconference was fully under way before 9:37, when the Pentagon was struck.” Furthermore, it states: “We do not know who from Defense participated, but we know that in the first hour none of the personnel involved in managing the crisis did. And none of the information conveyed in the White House video teleconference, at least in the first hour, was being passed to the NMCC [in the Pentagon].” Clarke’s video teleconference is not connected into the area of the NMCC from where the crisis is being managed. Consequently, “the director of the operations team-who was on the phone with NORAD-did not have the benefit of information being shared on the video teleconference.” And, “when the Secretary [of Defense Rumsfeld] and Vice Chairman [of the Joint Chiefs of Staff Myers] later participated in the White House video teleconference, they were necessarily absent from the NMCC and unable to provide guidance to the operations team.” Clarke, however, gives a specific recollection of Myers speaking over video at 9:28, which is seemingly at odds with the 9/11 Commission’s account (see 9:28 a.m. September 11, 2001). One witness later recalls: “[It] was almost like there were parallel decision-making processes going on; one was a voice conference orchestrated by the NMCC… and then there was the [White House video teleconference].… [I]n my mind they were competing venues for command and control and decision-making.” [9/11 Commission, 7/24/2004]

Brent Scowcroft.Brent Scowcroft. [Source: Publicity photo]An E-4B National Airborne Operations Center (NAOC) takes off from Andrews Air Force Base, just outside Washington, DC. The E-4B is a militarized version of a Boeing 747. Its purpose is to provide the president, vice president, and Joint Chiefs of Staff with an airborne command center that could be used to execute war plans and coordinate government operations during a national emergency. The E-4B taking off from Andrews, which has the call sign “Word 31,” is carrying civilian and military officials, and is launched in order to participate in a previously scheduled military exercise, according to journalist and author Dan Verton. [Federal Aviation Administration, 9/11/2001 pdf file; Verton, 2003, pp. 143-144; 9/11 Commission, 2/17/2004; NET Nebraska, 9/2/2011] This exercise would be Global Guardian, which is being conducted by the US Strategic Command (Stratcom) to test its ability to fight a nuclear war (see 8:30 a.m. September 11, 2001). Two other E-4Bs are also participating in Global Guardian today (see Before 9:00 a.m. September 11, 2001). [Omaha World-Herald, 2/27/2002]
Plane Ends Participation in Exercise after Taking Off - The E-4B taking off from Andrews Air Force Base is supposed to be using and testing its sophisticated technology and communications equipment for the exercise. It has “only just taken off” at the time the Pentagon is hit—9:37 a.m.—according to Verton. [Verton, 2003, pp. 144] But the flight tracking strip from Andrews will record it as having taken off at 9:27 a.m., 10 minutes before the Pentagon is hit. [Federal Aviation Administration, 9/11/2001 pdf file; 9/11 Commission, 2/17/2004] The crew will later be informed that after the plane launches, it flies “right over the top of the aircraft that eventually impacted the Pentagon.” [Flying K, 9/7/2012 pdf file] After taking off, the E-4B is “immediately ordered to cease the military exercise it was conducting and prepare to become the actual National Airborne Operations Center,” Verton will write. [Verton, 2003, pp. 144] (Global Guardian was reportedly put on pause at 9:11 a.m. (see 9:11 a.m. September 11, 2001), but it is not formally terminated until 10:44 a.m. (see (10:44 a.m.) September 11, 2001). [Bombardier, 9/8/2006 pdf file] ) The plane then converts “on the fly from exercise status to real-world crisis management.” [Verton, 2003, pp. 150]
Plane Flies Former National Security Adviser to Base in Nebraska - Former National Security Adviser Brent Scowcroft and his staff are on the E-4B, which will fly them to Offutt Air Force Base in Nebraska (see (Shortly After 9:03 a.m.) September 11, 2001). [Flying K, 9/7/2012 pdf file] The original plan had been for the aircraft to take them to Offutt to observe the Global Guardian exercise today. [Omaha World-Herald, 2/27/2002] After reaching the base, the E-4B will take off again and resume its airborne operations. [Flying K, 9/7/2012 pdf file] Minutes after the Pentagon is attacked, an unidentified four-engine jet plane will be seen circling above the White House (see (9:41 a.m.-9:42 a.m.) September 11, 2001). CNN will suggest this is an E-4B, so it is possible it is “Word 31.” [CNN, 9/12/2007] Another E-4B, with the call sign “Venus 77,” will take off from Andrews Air Force Base at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001).

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

A helicopter belonging to the US Park Police Aviation Unit.A helicopter belonging to the US Park Police Aviation Unit. [Source: United States Park Police]A US Park Police helicopter is directed to intercept the aircraft that subsequently hits the Pentagon, according to the later statements of US Navy historian John Darrell Sherwood. The helicopter’s pilot reportedly describes the incident when later interviewed by a US Marine Corps historian. Details of the pilot’s account are then revealed by Sherwood, who is a colleague of the Marine Corps historian, while he is interviewing Jeffrey Mark Parsons of the United States Border Patrol about his experiences of the 9/11 attacks.
Pilot Is Told to Prevent the Plane from Hitting the Pentagon - According to Sherwood, the helicopter pilot, who is “an aviation sergeant with the United States Park Police,” is “in the area [of the Pentagon] and he got a call saying, ‘Try to intercept this plane, try to distract the plane, try to do something to, you know, prevent the plane from going into the Pentagon.’” It is unclear from what Sherwood says whether the helicopter is on the ground or already airborne at this time. In response to the instruction, the helicopter goes “to try to distract” the approaching aircraft.
Helicopter Is Witnessed near the Pentagon - What is apparently this Park Police helicopter is then witnessed by Parsons out of a window on the 17th floor of the hotel he is staying at. Parsons sees it flying toward the helicopter landing pad at the Pentagon, two or three minutes before the Pentagon is attacked. [US Naval Historical Center, 12/13/2001; Goldberg et al., 2007, pp. 258] Other individuals near or inside the Pentagon see what is presumably the same helicopter around this time (see (9:35 a.m.-9:36 a.m.) September 11, 2001 and Shortly Before 9:37 a.m. September 11, 2001). [CNN, 9/11/2001; Washington Post, 9/5/2002; Priess, 2016, pp. 244-245] Parsons has been staying at the Marriott Residence Inn in Arlington, near the Pentagon, for almost a month, but, he will recall, he has “never seen a helicopter approach the Pentagon from that direction before.”
Pilot Sees the Pentagon Attack - At some point, the helicopter lands for a period near the Pentagon. According to Sherwood, it “landed, at one point, near the Memorial Bridge, and there’s that strip of land before you get to the Memorial Cemetery.” Its pilot reportedly witnesses the attack on the Pentagon. He “saw the plane go in, and then the next thing he started doing is medevacing people out of there,” according to Sherwood. When told while being interviewed by Sherwood that the helicopter pilot is instructed to intercept a plane approaching the Pentagon, Parsons will ask, “Then they knew [the plane] was headed toward the Pentagon before it actually hit the Pentagon, then?” To this, Sherwood will only answer, “I guess that helicopter swung around, but by the time he got around, the plane was already into the building.”
Park Police Flies Huey Helicopters - The helicopter is a white and blue Huey, according to Sherwood. [US Naval Historical Center, 12/13/2001] The Park Police Aviation Unit has two Bell 412 helicopters. [Aviation International News, 10/1/2001; Rotor and Wing, 11/2001; Rotor and Wing, 2/2002; National Park Service, 10/16/2004] (The Bell 412 is a more modern version of the “Huey” helicopter. [New York Times, 8/24/2003; USA Today, 10/25/2007] ) The aviation unit is located in Anacostia Park in southeast Washington, across the Potomac River from the Pentagon. [Aviation International News, 10/1/2001; National Park Service, 10/16/2004]
Witness Will Be Told, 'Don't Tell Anyone about' the Incident - Most accounts of the unit’s actions on this day will make no mention of this incident, and only describe Park Police helicopters taking off in the minutes after the attack on the Pentagon (see Shortly After 9:37 a.m. September 11, 2001). [Rotor and Wing, 11/2001; NBC 4, 9/11/2003; McDonnell, 2004, pp. 20 pdf file; Goldberg et al., 2007, pp. 161-162] However, it appears there may be an attempt to keep the incident secret. After Parsons recalls seeing the helicopter near the Pentagon minutes before the attack there, Sherwood will instruct him: “Don’t tell anyone about that story, because that’s one of our, I think that’s one of the best stories that’s going to come out of this. We don’t want the press to get this.” [US Naval Historical Center, 12/13/2001]

A number of witnesses see a helicopter flying near the Pentagon in the minutes before the attack there.
bullet Jeffrey Mark Parsons, an assistant chief patrol agent with the United States Border Patrol, sees a blue and white helicopter that appears as if it is coming in to land, from a window on the 17th floor of the hotel he is staying at, near the Pentagon. Parsons will later recall that two or three minutes before the Pentagon attack occurs: “I saw [the helicopter] circle… between the hotel and the Pentagon, going toward the landing pad [at the Pentagon] where that airliner ultimately hit. And I thought that he landed on the pad.” Parsons will say the helicopter flies in at “a weird angle,” and recall that he has been staying at the Marriott Residence Inn in Arlington for almost a month, but has “never seen a helicopter approach the Pentagon from that direction before.” He will recognize the helicopter as a Huey because he has flown Hueys and knows they make “a very distinct sound.” According to John Darrell Sherwood, a Navy historian who interviews Parsons about the incident, the helicopter belongs to the US Park Police and has been instructed to intercept the aircraft that subsequently hits the Pentagon (see Shortly Before 9:35 a.m. September 11, 2001). [US Naval Historical Center, 12/13/2001; Goldberg et al., 2007, pp. 258]
bullet A senior Air Force officer who is somewhere outside the Pentagon also sees a helicopter circling the Pentagon around this time, although he believes it to be a US military helicopter. Shortly after the Pentagon attack, the unnamed officer will tell a CNN reporter that the helicopter “disappeared behind the building where the helicopter landing zone is… and he then saw [a] fireball go into the sky” when the Pentagon is hit. [CNN, 9/11/2001]
bullet Jennifer Reichert, who is stuck in traffic on Route 27 in front of the Pentagon, will describe that just before the attack, “A helicopter takes off from the heliport at the Pentagon.” She will add: “Minutes—maybe seconds—later, I hear it: American Airlines Flight 77 screams toward the Pentagon. The explosion [of the crash] shakes my car.” [Washington Post, 9/5/2002]
bullet Secretary of Defense Donald Rumsfeld and Denny Watson, his CIA briefer, who are in Rumsfeld’s office at the Pentagon, see a helicopter flying very close to the building, outside the window of the office, and then pulling away just before the building is attacked (see Shortly Before 9:37 a.m. September 11, 2001). [Priess, 2016, pp. 244-245]
Perhaps due to the presence of this helicopter in the area, some people will initially think the attack on the Pentagon involves a helicopter hitting the building. Captain William Durm, the commander of the Pentagon’s Triservice Dental Clinic, will head to the building’s center courtyard shortly after the Pentagon is hit. Someone there will tell him a helicopter has hit the other side of the building. [Office of Medical History, 9/2004, pp. 11] Some early news reports will suggest a helicopter crashed into the Pentagon. [Thomas Crosbie Media, 9/11/2001; Poynter Institute, 9/2/2002] One report will claim that “one aircraft and a helicopter have crashed into the Pentagon.” [Airline Industry Information, 9/11/2001] Vice President Dick Cheney will tell NBC’s Meet the Press that “the first reports on the Pentagon attack suggested a helicopter” hit the building. [Meet the Press, 9/16/2001] The Guardian will report that one witness claims the explosion that occurs when the Pentagon is hit blows up a helicopter circling overhead. [Guardian, 9/12/2001] New York Times columnist William Safire will report that, at approximately this time, Cheney is told that either another plane or “a helicopter loaded with explosives” is heading for the White House.

Secretary of Defense Donald Rumsfeld and Denny Watson, his CIA briefer, see a helicopter flying very close to the Pentagon, just outside the window of Rumsfeld’s office, shortly before the Pentagon is attacked. [Priess, 2016, pp. 244-245] Watson has been giving Rumsfeld his daily intelligence briefing in his office at the Pentagon and they are both aware of the crashes at the World Trade Center (see (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 37; Rumsfeld, 2011, pp. 335] Rumsfeld is skimming through a copy of the President’s Daily Brief when the sound of a helicopter outside causes him to stop what he is doing. The helicopter, which is blue and white, is “hovering so close to the window that I could see what one of the men in it looked like,” Watson will later recall. He has “dark hair, a beard and a mustache, and reflector sunglasses.” Rumsfeld and Watson talk about how easy it would be for the pilot to turn the helicopter and crash into Rumsfeld’s office. Finally, the helicopter pulls away from the Pentagon. As it does, Rumsfeld and Watson feel the building shake due to it being attacked (see 9:37 a.m. September 11, 2001). [Priess, 2016, pp. 244-245] A number of other people will recall seeing a helicopter flying close to the Pentagon around this time (see (9:35 a.m.-9:36 a.m.) September 11, 2001). [CNN, 9/11/2001; Washington Post, 9/5/2002] One of them, Jeffrey Mark Parsons, will describe the helicopter he sees as being blue and white, so it is presumably the helicopter that Rumsfeld and Watson see. The helicopter belongs to the US Park Police and its pilot has been directed to try and intercept a plane, presumably Flight 77, that was approaching the Pentagon, according to US Navy historian John Darrell Sherwood (see Shortly Before 9:35 a.m. September 11, 2001).

According to most accounts, at the time the Pentagon is hit, Defense Secretary Donald Rumsfeld is in his office on the third floor of the Pentagon’s outer E Ring, receiving his daily intelligence briefing. [New York Times, 9/12/2001; Woodward, 2002, pp. 24; 9/11 Commission, 3/23/2004; Clarke, 2006, pp. 221; Cockburn, 2007, pp. 1; Goldberg et al., 2007, pp. 130; Vogel, 2007, pp. 438-439] As he later recalls, “the building shook and the tables jumped.” [Goldberg et al., 2007, pp. 130] Although he has been informed of the two aircraft hitting the World Trade Center (see Shortly After 8:46 a.m. September 11, 2001 and (Shortly After 9:03 a.m.) September 11, 2001), he supposedly does not initially suspect a plane has hit the Pentagon, thinking instead that a bomb has gone off. [ABC News, 9/16/2001; MSNBC, 9/30/2001; Washington Post, 1/9/2002] In his nearby office, Rumsfeld’s senior military assistant Vice Admiral Edmund Giambastiani Jr. also hears the explosion, and walks through his doorway toward Rumsfeld’s office. As the two meet, Rumsfeld asks Giambastiani, “What the hell’s happening?” [American Forces Press Service, 9/8/2006; Goldberg et al., 2007, pp. 130] Rumsfeld then looks out his window but, he later recalls, sees “nothing here.” [Parade Magazine, 10/12/2001; Washington Post, 1/9/2002] He goes into the hallway and, accompanied by his security guards, hurries toward the crash site (see 9:38 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 130] However, counterterrorism “tsar” Richard Clarke will later contradict these accounts. Clarke indicates that Rumsfeld has been participating in the video teleconference conducted from the White House Situation Room since shortly after the second WTC crash (see (9:10 a.m.) September 11, 2001). He claims that Rumsfeld is still involved in this conference at the time the Pentagon is hit, and he tells his deputy, “I can still see Rumsfeld on the screen, so the whole building didn’t get hit.” [Clarke, 2004, pp. 2-3 and 7-8] If Clarke’s account were correct, this would presumably mean Rumsfeld is in the Pentagon’s Executive Support Center (ESC), which has secure video facilities, rather than in his office. [Washington Times, 2/23/2004] But according to other accounts, Rumsfeld does not go to the ESC until around 10:15 a.m., after he returns from the crash site (see (10:00 a.m.-10:30 a.m.) September 11, 2001).

Davison Army Airfield.Davison Army Airfield. [Source: Airnav.com]Shortly after the Pentagon crash, an air traffic control supervisor at Davison Army Airfield sees two unidentified aircraft near the Pentagon on the radar of his facility, which is located at Fort Belvoir, about 12 miles south of the Pentagon. The supervisor, who is working in the airfield’s control tower, looks out the window toward where the Pentagon is and sees a large black cloud of smoke. He is told by a colleague that news reports are saying a small airplane has hit the Pentagon. He then looks at the facility’s radar scope, which shows two aircraft circling above the Pentagon. The transponder of one of these is transmitting the emergency code. The supervisor will recall: “I look at where the Pentagon area is [on the radar scope], and I look, and there was an aircraft squawking 7700, meaning emergency. And it was circling—it was coming down and fast.… [A]nd there was another target with no markings or anything—it was just a target,” with none of the accompanying information that would be emitted by a transponder. This second aircraft is “descending rapidly and very fast.” The supervisor will recall that the two aircraft “circled around and both tags they disappeared. But they stay in the air.” He will provide no further information on the identities of the aircraft or why one of them is transmitting the emergency code. [US Army Center for Military History, 11/14/2001 pdf file] There will be eyewitness accounts of aircraft near the Pentagon around this time (see (9:35 a.m.-9:36 a.m.) September 11, 2001, 9:37 a.m. September 11, 2001, and (9:41 a.m.-9:42 a.m.) September 11, 2001).

The Pentagon on fire.The Pentagon on fire. [Source: Press Association]Television news reports describe an explosion and fire occurring at the Pentagon, but do not specify that a plane hit it:
bullet Two seconds after 9:39 a.m., reporter Jim Miklaszewski states on NBC News: “I don’t want to alarm anybody right now, but apparently, there—it felt, just a few moments ago, like there was an explosion of some kind here at the Pentagon. We’re on the E-ring of the Pentagon. We have a window that faces out toward the Potomac, toward Kennedy Center. We haven’t been able to see or—or hear anything after the initial blast. I just stepped out in the hallway. Security guards were herding people out of the building, and I saw just a moment ago as I looked outside, a number of construction workers who have been working here, have taken flight. They’re running as far away from the building as they can right now. I—I hear no sirens going off in the building; I see no smoke, but the building shook for just a couple of seconds. The windows rattled and security personnel are doing what they can momentarily to clear this part of the building. Again, I have no idea whether it was part of the construction work, whether it was an accident or what is going on. We’re going to try to find those details and get them to you as soon as possible. But interestingly enough, one intelligence official here in the building said when he saw what appeared to be the coordinating attack on the World Trade Center, his advice was to stay away from the outside of the building today just in case.” [NBC, 9/11/2001]
bullet At 9:40, CNN coverage includes a banner stating, “Reports of fire at Pentagon.” [CNN, 9/11/2001] Three minutes later, CNN producer Chris Plant reports from the Pentagon: “It’s impossible for me to say… exactly what caused this. I did not hear an explosion but there is certainly a very, very significant fire in this enormous office building.” [CNN, 9/11/2001]
bullet At 9:42, ABC News reports smoke coming from somewhere behind the Old Executive Office Building, next to the White House. Two minutes later it reports a “fire confirmed at the Pentagon.” [ABC News, 9/11/2001]
bullet At 9:43, CBS News reports “smoke pouring out of the Pentagon,” but adds, “We don’t know whether this is the result of a bomb or whether it is yet another aircraft that has targeted a symbol of the United States’ power.” [CBS, 9/11/2001]
However, no media outlets record video footage of the Pentagon crash, and the cause of the explosion remains unknown for some minutes afterward. The Associated Press is apparently the first source to report that a plane hit the Pentagon (see 9:43 a.m.-9:53 a.m. September 11, 2001).

The ‘white jet’ seen circling above the White House and Capitol. The ‘white jet’ seen circling above the White House and Capitol. [Source: Discovery Channel]Several television networks interrupt their coverage of events in New York to report that a mysterious white aircraft is circling over the White House and the Capitol.
bullet At 9:41 a.m., Peter Jennings of ABC News reports that “there is a plane circling the White House at the moment. And they’re clearing the grounds there.… And this plane circling the White House adds to the trauma that people are feeling today, but we have no idea precisely what the means.” [ABC News, 9/11/2001]
bullet At 9:52 a.m., CNN correspondent John King, who is standing about 200 yards from the White House, says: “About 10 minutes ago, there was a white jet circling overhead. Now, you generally don’t see planes in the area over the White House. That is restricted air space. No reason to believe that this jet was there for any nefarious purposes, but the Secret Service was very concerned, pointing up at the jet in the sky. It is out of sight now, best we can tell.” [CNN, 9/11/2001] Another CNN correspondent, Kate Snow, also reports seeing a plane at around this time, “circling over the Capitol.” She says: “Now whether that may have been an Air Force plane, it’s unclear. But that seemed to be the reason, according to security guards that I talked with, towards the evacuation of the Capitol.” [CNN, 9/11/2001] (The Capitol is reportedly evacuated at 9:48 a.m. (see 9:48 a.m. September 11, 2001). [Fox News, 9/11/2003] )
bullet At 9:55 a.m., NBC News turns to a live report from its correspondent Bob Kur, who recalls: “And in the most surreal of this morning’s scenes here at the White House, a white plane, a very big jet, was flying an unusual pattern near the White House over Lafayette Park, very slowly. It made one circle and then we have not seen it since. There was a lot of concern about what that plane might be. But, again, it’s only speculation, but most people say that since flights have been cleared from US air space, and it was a totally white plane, looked unusual to all of us, that it was a government plane of some kind.” [NBC 4, 9/11/2001]
A CNN comparison between video footage of this plane and an official Air Force photograph will suggest it is an E-4B. This is a militarized version of a Boeing 747 that is used as a flying command post. An E-4B has in fact just been launched from Andrews Air Force Base, just outside Washington, DC (see (9:27 a.m.) September 11, 2001), so this could plausibly be the same plane as is witnessed by the reporters. Two government sources familiar with the incident will later tell CNN the plane was a military aircraft, but that its details are classified. Even by 2007, the Pentagon, FAA, and Secret Service will have offered no public explanation for this plane over the White House. [Verton, 2003, pp. 143-144; CNN, 9/12/2007] In 2009, John Farmer, the former senior counsel to the 9/11 Commission, will claim that this “mystery plane” is an E-4B with the call sign “Venus 77” that takes off from Andrews Air Force Base at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001).

Initial television reports stated there had been an explosion at the Pentagon, but not that a plane caused it (see 9:39 a.m.-9:44 a.m. September 11, 2001). Minutes later, there is still uncertainty over what caused the explosion.

The US military has four of these planes. [Federation of American Scientists, 4/23/2000; Dayton Daily News, 9/12/2001; Verton, 2003, pp. 143] Venus 77 takes off at 9:43 a.m., according to John Farmer, who will be senior counsel to the 9/11 Commission. [Farmer, 2009, pp. 206] But the flight tracking strip from Andrews Air Force Base will record it as having taken off at 9:45 a.m. [Federal Aviation Administration, 9/11/2001 pdf file; 9/11 Commission, 2/17/2004] The plane is initially directed toward Offutt Air Force Base in Nebraska. But shortly after taking off, its pilot tells air traffic control that he wants to fly to Wright-Patterson Air Force Base in Ohio. [Farmer, 2009, pp. 206] Wright-Patterson is one of the few designated bases for the E-4B. Another E-4B has actually been on the ground there and takes off around this time (see Shortly After 9:37 a.m. September 11, 2001). [Dayton Daily News, 9/12/2001] The pilot of Venus 77 is cleared to head to Wright-Patterson and so he turns west. But he then says he wants to turn back east and hold south of Washington. He will be cleared to do so at 9:47 a.m. and his plane will eventually settle into a holding pattern over Richmond, Virginia. [Farmer, 2009, pp. 206-207] Farmer will claim that Venus 77 is the “mystery plane”—an unidentified white aircraft—seen over Washington around this time (see (9:41 a.m.-9:42 a.m.) September 11, 2001).

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

Eventually… the personal BlackBerrys that bring your e-mail to you, they went down. And inside the Capitol, remember [there are] still switchboard operators there. Inside the Capitol, the phones worked only on and off.” According to Senator Edward Kennedy (D-MA), there is “no communication whatsoever going on.” [CNN, 9/11/2002] Senate Majority Leader Tom Daschle (D-SD) will recall: “People were punching their cell phones to no avail. The lines were jammed.” [Daschle and D'Orso, 2003, pp. 110] Consequently, for more than an hour Daschle’s own staff is unable to establish where he is. [Washington Post, 1/27/2002] House Speaker Dennis Hastert (R-IL) was experiencing communications problems even before he was evacuated from the Capitol, while trying to contact Vice President Dick Cheney by phone (see (9:04 a.m.-9:45 a.m.) September 11, 2001). [Hastert, 2004, pp. 6; Hayes, 2007, pp. 336] Whether others at the Capitol also experienced similar difficulties prior to the evacuation is unclear. What causes these problems is uncertain. However, numerous other people in the Washington area, including senior government officials, also experience serious communications problems throughout the day (see (After 8:55 a.m.) September 11, 2001).

Speaker of the House Dennis Hastert (R-IL), who is third in line for the presidency, is evacuated from the US Capitol building and flown to a secret underground bunker in Virginia, where he remains until late in the afternoon. [ABC News, 9/11/2001; ABC News, 9/15/2002] Around 9:48, the Capitol building had begun evacuating (see 9:48 a.m. September 11, 2001). At that time, Hastert was on the House floor. Two members of his security detail now enter the chamber and tell him, “We’re going to evacuate the Capitol, and you’re going to a secure location.” They take him out of the building and drive him hurriedly to Andrews Air Force Base, ten miles southeast of Washington. After he arrives there, Hastert is finally able to communicate with Vice President Dick Cheney, who is at the White House. (Hastert had been trying to contact Cheney earlier on, but without success (see (9:04 a.m.-9:45 a.m.) September 11, 2001.) Cheney tells Hastert: “There’s a real danger. I want you to go to a secure location.” [Hastert, 2004, pp. 8-9] Hastert gets on a helicopter and is flown to the secret underground bunker at Mount Weather in Bluemont, Virginia, 48 miles outside Washington—about 20 minutes journey by air. [Bulletin of the Atomic Scientists, 11/2001; ABC News, 9/15/2002; Bamford, 2004, pp. 81] In the following hours, other top members of the House and Senate leaderships will join him there (see (Between Late Morning and Early Afternoon) September 11, 2001). [ABC News, 9/11/2001; Hastert, 2004, pp. 10] Hastert remains at the secure facility for several hours, and will return to Washington late in the afternoon (see (Between 5:00 p.m. and 6:00 p.m.) September 11, 2001). [Daily Herald (Arlington Heights), 9/11/2002] Hastert’s evacuation to Mount Weather is the result of “Continuity of Government” (COG) orders, which provide for evacuating the third and fourth in the line of presidential succession during a national emergency, in order to protect the nation’s constitutional leadership. [Washington Post, 1/27/2002] Counterterrorism “tsar” Richard Clarke activated the COG plan shortly before 10:00 a.m. this morning (see (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001).

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

It was hit by Flight 175 at 9:03 a.m., 56 minutes earlier (see 9:03 a.m. September 11, 2001).

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

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

US military installations are placed on the highest state of alert, known as Force Protection Condition Delta (FPCON Delta), in response to the terrorist attacks in New York and at the Pentagon. The raised threat level applies to every US military installation across the country and around the world, and every member of the US armed forces. [Associated Press, 9/11/2001; US Department of Defense, 9/11/2001; New York Times, 9/12/2001] Measures that are taken once FPCON Delta has been declared include placing more guards on duty at installations, having all vehicles on installations identified, and having all personnel positively identified. Additionally, all suitcases, briefcases, and packages brought into an installation must be searched. [Slate, 9/12/2001]
Rumsfeld and Myers Decide to Raise FPCON - The decision to raise the force protection condition is apparently made by Secretary of Defense Donald Rumsfeld and/or acting Chairman of the Joint Chiefs of Staff Richard Myers. Rumsfeld will tell the 9/11 Commission that after he arrives at the Pentagon’s National Military Command Center (NMCC) (see (10:30 a.m.) September 11, 2001), he and Myers “discussed, and I recommended… increasing the force protection level.” [9/11 Commission, 3/23/2004] Myers will later write that after he arrives at the NMCC (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001), he “recommended that all American military commands and units worldwide go to [FPCON] Delta.” He will add: “Terrorists had staged major attacks in New York and Washington. Although we did not yet have reliable intelligence on when and where they would strike next, it seemed likely that they would.” [Myers, 2009, pp. 153] But White House counterterrorism chief Richard Clarke will write that he gave the instruction to raise the force protection condition, at around 9:30 a.m. (see (9:29 a.m.) September 11, 2001). [Clarke, 2004, pp. 5-6]
Conflicting Times Given for Raising of FPCON - The exact time at which the force protection condition is raised is unclear. CNN’s Barbara Starr will report that “all US military forces [are] ordered to Condition Delta” at 10:10 a.m. [CNN, 9/4/2002] However, other evidence indicates the force protection condition is raised at a later time, around 10:35 a.m. Rumsfeld only enters the NMCC at about 10:30 a.m., indicating it is raised after that time. [9/11 Commission, 7/24/2004, pp. 43-44] And at 10:38 a.m., after Vice President Dick Cheney asks him on the air threat conference call if US forces are on “heightened alert,” Rumsfeld will reply, “Yes,” and say they are at FPCON Delta. [US Department of Defense, 9/11/2001 pdf file]
Some Areas Already at FPCON Delta - Although the entire US military is now under the same FPCON level, usually, different locations can have different FPCON levels. [Slate, 9/12/2001] US forces in some parts of the world, particularly the Middle East and the Persian Gulf region, are in fact already at FPCON Delta. [New York Times, 9/12/2001] (The force protection condition was raised in those areas in late June, after intelligence reports suggested that terrorists might attack American military or civilian targets in the region (see June 21, 2001). [Los Angeles Times, 6/23/2001; National Public Radio, 5/23/2002; 9/11 Commission, 7/24/2004, pp. 257] ) Shortly after the force protection condition is raised, Rumsfeld will order that the defense readiness condition also be raised (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 326, 554]
Five Possible Force Protection Conditions - The force protection condition is a “chairman of the Joint Chiefs of Staff-approved standard for identification of, and recommended responses to, terrorist threats against US personnel and facilities,” according to the Department of Defense. [US Department of Defense, 11/8/2011 pdf file] It was created in June 2001 and replaced the “terrorist threat condition,” or “Threatcon.” [Los Angeles Times, 1/22/2002] There are five possible force protection conditions. The lowest, FPCON Normal, means no threat of terrorist activity is present. The other conditions are Alpha, Bravo, Charlie, up to the highest, FPCON Delta, which means a terrorist attack has occurred or intelligence has been received indicating that action against a specific location is likely.

Defense Secretary Donald Rumsfeld, missing for at least 30 minutes, finally enters the NMCC, where the military’s response to the 9/11 attacks is being coordinated. [CNN, 9/4/2002; 9/11 Commission, 6/17/2004] Rumsfeld later claims that he only started to gain a situational awareness of what was happening after arriving at the NMCC. [9/11 Commission, 6/17/2004] Rumsfeld was in his office only 200 feet away from the NMCC until the Pentagon crash at 9:37 a.m. (see 9:37 a.m. September 11, 2001). His activities during this period are unclear. He went outside to the Flight 77 crash site and then stayed somewhere else in the Pentagon until his arrival at the NMCC.

Personnel in the White House Situation Room learn of a plane supposedly flying toward the United States from Europe that appears to be hijacked, but it is subsequently determined that the alleged flight does not exist. Those in the Situation Room receive word confirming that a suspicious Northwest Airlines flight from Portugal to Philadelphia is heading toward Washington, DC. The plane is not responding to radio calls and its transponder is squawking the code for a hijacking. White House counterterrorism chief Richard Clarke gives orders for someone to find out more about the flight and what assets the US military has available to intercept it at the coast. Meanwhile, the FAA searches its data for information about the flight and officials try to contact Northwest Airlines to find out more. Those participating in Clarke’s video teleconference (see (9:10 a.m.) September 11, 2001 and 9:25 a.m. September 11, 2001) grow increasingly anxious, since no action can be taken until more details about the flight are found. Then Timothy Flanigan, the deputy White House counsel, who is in the Situation Room, has an idea. He leaves the room and finds an unsecure computer. On this, he searches travel websites for details of the suspicious flight, but finds nothing. He then checks on the Northwest Airlines website and again finds no reference to the flight. He quickly jots down everything he can find about Northwest Airlines flights from Europe and then goes to pass on his findings. After taking a seat at the conference table, he addresses Clarke, who is still searching for information about the plane. “I’ve checked and there’s no such flight,” he says. Astonished at this news, Clarke asks, “How did you check?” “I looked on their website,” Flanigan replies. Clarke then passes on the news to the other participants in the video teleconference. “I have information that there is no such flight,” he says and adds, “Check that again.” [Eichenwald, 2012, pp. 36-37] The 9/11 Commission Report will later note that there are “multiple erroneous reports of hijacked aircraft” this morning (see (9:09 a.m. and After) September 11, 2001).

Vice President Dick Cheney tries to bring Defense Secretary Donald Rumsfeld up to date over the National Military Command Center’s (NMCC) conference call (see 9:29 a.m.-9:34 a.m. September 11, 2001), as Rumsfeld arrived at the NMCC just minutes earlier (see (10:30 a.m.) September 11, 2001). Cheney explains that he has given authorization for hijacked planes to be shot down and that this has been passed on to the fighter pilots. Rumsfeld asks, “So we’ve got a couple of aircraft up there that have those instructions at the present time?” Cheney replies: “That is correct. And it’s my understanding they’ve already taken a couple of aircraft out.” Then Rumsfeld says: “We can’t confirm that. We’re told that one aircraft is down but we do not have a pilot report that they did it.” Cheney is incorrect about his authorization having reached the pilots (see 10:31 a.m. September 11, 2001).

Defense Secretary Donald Rumsfeld refuses to leave the Pentagon, despite the smoke leaking into the National Military Command Center (NMCC) where he is currently working, the danger of a second attack on the Pentagon, and a White House request to begin implementing Continuity of Government (COG) measures. [Goldberg et al., 2007, pp. 132] After being out of touch with his colleagues at the Pentagon since the time of the attack there (see (9:38 a.m.-10:00 a.m.) September 11, 2001 and 9:39 a.m. September 11, 2001), Rumsfeld finally entered the NMCC at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 43-44; Cockburn, 2007, pp. 2-6] It is now noticed that smoke is seeping into the center. With people beginning to cough, aides suggest Rumsfeld should leave the building, but he is uninterested in their advice. Even when they warn that the smoke might be toxic, he still ignores them. Rumsfeld’s deputy, Paul Wolfowitz, tells him he should leave the Pentagon. But Rumsfeld instead orders Wolfowitz to leave the NMCC and fly to Site R, the alternate command center outside Washington (see (11:00 a.m.) September 11, 2001). According to journalist and author Steve Vogel, this is “contrary to the established Continuity of Government plan, which called for the secretary of defense to relocate to the alternate command center.… The secretary figured the 45 minutes to an hour it would take to evacuate to Site R would leave him out of touch for too long.” Rumsfeld will later explain: “That’s life. That’s what deputies are for.” [Vogel, 2007, pp. 441]

The US military’s defense readiness condition is raised from Defcon 5, the lowest possible level, to Defcon 3, an intermediate level that requires a heightened alert status for US armed forces worldwide, and which is the highest the defense readiness condition has been for 28 years. [Historical Office, Office of the Secretary of Defense, 7/18/2002 pdf file; 9/11 Commission, 7/24/2004, pp. 326, 554; Goldberg et al., 2007, pp. 131; Rumsfeld, 2011, pp. 338]
Rumsfeld Recommends Raising Defcon - The decision to go to Defcon 3 is reportedly made by Secretary of Defense Donald Rumsfeld. [US Department of Defense, 8/12/2002] Rumsfeld will later recall that after he arrives at the Pentagon’s National Military Command Center (NMCC) (see (10:30 a.m.) September 11, 2001), he talks with General Richard Myers, the vice chairman of the Joint Chiefs of Staff, and “[w]e discussed and I recommended raising the defense condition level from five to three.” [9/11 Commission, 3/23/2004]
Teleconference Participants Told to 'Hold Off' on Defcon 3 - Rumsfeld directs that the US military go to Defcon 3. At 10:43 a.m., it is announced on the air threat conference call that the secretary of defense “has directed that we go to Defcon 3 and be prepared to go to [Defcon] 2.” However, a minute later, Rumsfeld talks to Vice President Dick Cheney on the conference call, and Cheney says he will have to run the decision to go to Defcon 3 by the president, “and let him make the call.” Therefore, at 10:45 a.m., those on the conference call are told to “hold off on Defcon 3.”
Order to Raise Defcon Reinstated - But Rumsfeld believes raising the defense readiness condition is urgent. [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 326, 554] There is therefore a “historical discussion about how the move to Defcon 3 went during previous crises, Cuba specifically [i.e. the Cuban missile crisis in 1962],” Captain Charles Leidig, who is also in the NMCC, will later recall. With their reference being “a book on the shelf,” according to Leidig, Myers is shown that he has “approval authority to go to Defcon 3.” [9/11 Commission, 4/29/2004 pdf file] After consulting Defense Department directives, Rumsfeld concludes that he has the authority to issue the order to raise the defense readiness condition. [9/11 Commission, 7/24/2004, pp. 554] Therefore, at 10:46 a.m., those on the air threat conference call are told: “Override last instructions. The vice chairman [i.e. Myers] is directing we go to Defcon 3.” A few minutes later, an announcement is made on the conference call, “Emergency action message released at 14:52 [Zulu time, i.e. 10:52 a.m. Eastern time], re: Defcon 3.” [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 2004]
Raising Defcon Is a 'Huge Move' - Rumsfeld will later agree with an interviewer that raising the defense readiness condition is “a very serious step for the nation.” [US Department of Defense, 8/12/2002] It was last raised to Defcon 3 during the 1973 Arab-Israeli war, when Rumsfeld had been the United States ambassador to NATO. Regarding the decision to raise it, Myers tells Rumsfeld, “It’s a huge move, but it’s appropriate.” [US Department of Defense, 1/9/2002; Wall Street Journal, 3/22/2004 pdf file; Rumsfeld, 2011, pp. 338]
President Later Told of Decision - The decision to go to Defcon 3 will soon be communicated within NORAD (see 11:03 a.m.-11:12 a.m. September11, 2001). [9/11 Commission, 6/17/2003; 9/11 Commission, 2004; 9/11 Commission, 2/3/2004 pdf file] Rumsfeld will brief President Bush on the decision (see (11:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 554; Bush, 2010, pp. 133] Apparently around the time the defense readiness condition is raised, Rumsfeld and/or Myers also decide to raise the force protection condition of US military installations (see (Between 10:10 a.m. and 10:35 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 3/23/2004; Myers, 2009, pp. 153]
Defcon 3 Intended for Cold War - Some individuals will later be critical of the decision to raise the defense readiness condition at this time. John Farmer, the senior counsel to the 9/11 Commission, will write that Defcon 3 is in fact “a Cold War-era designation, devised to respond to a nuclear threat.” [Farmer, 2009, pp. 235] According to Farmer and other 9/11 Commission staffers, it is “suited more to a Cold War conflict than to al-Qaeda’s attack.” [Rutgers Law Review, 9/7/2011 pdf file] General Ralph Eberhart, the commander of NORAD, will similarly say that Defcon 3 is “not intended for [events like] the attacks of 9/11 and thus could have complicated the response to the attacks.” He will say he does not think that raising the condition would have “done anything for us” within the continental United States. [9/11 Commission, 3/1/2004 pdf file]
Defcons Are Phased Increases in Combat Readiness - The defense readiness condition is a “uniform system of progressive alert postures for use between the chairman of the Joint Chiefs of Staff and the commanders of unified and specified commands, and for use by the [armed] services,” according to the Department of Defense. [US Department of Defense, 11/8/2011 pdf file] Defcons are phased increases in combat readiness and are graduated to match situations of varying military severity. They are numbered, from Defcon 5, which means “normal peacetime readiness,” down to Defcon 1, which means “maximum force readiness.” The current level, Defcon 3, represents an “increase in force readiness above normal readiness.” [Federation of American Scientists, 4/29/1998] The defense readiness condition will remain at Defcon 3 until three days later, when it will be reduced one notch, to Defcon 4 (see September 14, 2001).

The US Strategic Command (Stratcom) formally terminates its Global Guardian exercise at this time, according to a 2006 article in The Bombardier, the newspaper for Barksdale Air Force Base, Louisiana. Global Guardian was put on pause just over 90 minutes earlier, according to the same article (see 9:11 a.m. September 11, 2001). [Bombardier, 9/8/2006 pdf file] However, other reports will suggest that Global Guardian was canceled significantly earlier than 10:44 a.m. One article in the Omaha World-Herald will state, “When the second World Trade Center tower was hit,” at 9:03 a.m., “the exercise was canceled, and the battle staff [at Offutt Air Force Base, Nebraska] moved to the real-world crisis.” [Omaha World-Herald, 9/8/2002] But an earlier article in the World-Herald will say that military authorities canceled Global Guardian “after the attacks on the World Trade Center towers and the Pentagon,” suggesting some time after 9:37 a.m., when the Pentagon was hit. [Omaha World-Herald, 2/27/2002] An E-4B National Airborne Operations Center aircraft that was involved in Global Guardian was reportedly only told to pull out of the exercise just after the Pentagon was hit (see (9:27 a.m.) September 11, 2001).

Secretary of Defense Donald Rumsfeld speaks with President Bush, and they discuss the rules of engagement for fighter pilots and Rumsfeld’s decision to raise the defense readiness condition to Defcon 3. [9/11 Commission, 7/24/2004, pp. 465, 554] Rumsfeld is in the National Military Command Center (NMCC) at the Pentagon and Bush is on board Air Force One, flying toward Barksdale Air Force Base in Louisiana. [9/11 Commission, 3/23/2004; St. Petersburg Times, 7/4/2004] After Rumsfeld entered the NMCC at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001), he had been concerned with ensuring that fighter pilots defending US airspace have a clear understanding of their rules of engagement, so they know “what they could and could not do” (see (10:30 a.m.-1:00 p.m.) September 11, 2001). [9/11 Commission, 3/23/2004; 9/11 Commission, 7/24/2004, pp. 43-44] He also directed that the nation’s armed forces go to Defcon 3, an increased state of military readiness (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 326; Goldberg et al., 2007, pp. 131]
President Approves Decision to Raise Defcon - Rumsfeld now speaks with Bush and, according to the 9/11 Commission Report, tells him that the Department of Defense is “working on refining the rules of engagement, so pilots would have a better understanding of the circumstances under which an aircraft could be shot down.” Also at this time, according to the 9/11 Commission Report, Rumsfeld briefs Bush on his decision to raise the defense readiness condition to Defcon 3. When Rumsfeld ordered that the condition be raised, Vice President Dick Cheney told him to run the issue by the president; Rumsfeld replied that he would “call him shortly.” [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 465, 554] Bush gives Rumsfeld his approval for having raised the defense readiness condition. [Washington Post, 9/12/2001; Bush, 2010, pp. 133]
Defense Readiness Condition Possibly Discussed at Later Time - Although the 9/11 Commission Report will say Rumsfeld and Bush’s discussion of the defense readiness condition occurs at 11:15 a.m., in his 2010 book Decision Points, Bush will write that he approves Rumsfeld’s decision when he speaks to Rumsfeld from the office of Lieutenant General Thomas Keck at Barksdale Air Force Base. [Bush, 2010, pp. 133] If correct, this would mean the relevant phone call takes place sometime after 12:11 p.m., when Bush goes to Keck’s office (see (12:11 p.m.-1:20 p.m.) September 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).

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

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

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

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).

Several months into its investigation, the 9/11 Commission is already dissatisfied with the Department of Defense (see July 7, 2003).
Recorded Conversations Not Provided to Commission - When its staff take a tour of a Northeast Air Defense Sector (NEADS) facility in Rome, New York, which helped coordinate the air defense on the day of 9/11, the staff enter the operations room, which has “more than 20 banks of operators: some weapons controllers and some flight controllers.” The staff find that the operators’ conversations are always tape-recorded, but the tapes for 9/11 have not yet been sent to the Commission. In addition, according to Commission Chairman Tom Kean and Vice Chairman Lee Hamilton, “there were also discrepancies between things NORAD was telling [the Commission] about their performance on the morning of September 11—things that the agency had stated publicly after 9/11—and the story told by the limited tapes and documents the Commission had received.”
'Egregious' Failure - Upon learning of the existence of the tapes, team leader John Farmer immediately suspends the tour and the interviews and flies to meet Kean in New Jersey. [Kean and Hamilton, 2006, pp. 85-88] Farmer will say that the failure to produce the tapes was “egregious,” as, “Those tapes told the story of the air defense better than anything else that anyone could have given us.”
Subpoena Demanded - Farmer demands that a subpoena be issued to the Pentagon for the tapes. He tells Kean: “Listen, we have to subpoena this stuff. We may not get it, but if we don’t try to get it, how can you explain to the public that we have done our job?” Farmer is aware that it will be difficult to get a subpoena on the Pentagon—“When you’re talking about subpoenaing the DOD, the room goes quiet”—but he decides privately: “I would have quit if we didn’t. I felt we were becoming a laughingstock.” [Shenon, 2008, pp. 204]
Lost Time - Despite opposition from its Vice Chairman Lee Hamilton (see (Late October-Early November 2003)) and, allegedly, its Executive Director Philip Zelikow (see November 5, 2003), the Commission will subpoena NORAD for the tapes (see November 6, 2003). However, according to Kean and Hamilton, this means that “the staff had lost so much time that our hearing on the 9/11 story in the skies was postponed for months. Indeed, the delays from NORAD and the FAA made it highly unlikely that the team could complete its work as scheduled.” [Kean and Hamilton, 2006, pp. 85-88] Chapter 1 of the Commission’s final report will draw heavily on the tapes. [9/11 Commission, 7/24/2004, pp. 1-46]
Contrast with Other Aspects of Investigation - However, the Commission does not make the same effort with all day of 9/11 recordings. For example, it does not even find out which person(s) from the Department of Defense participated in a White House video conference chaired by counterterrorism “tsar” Richard Clarke during the attacks (see (9:10 a.m.) September 11, 2001).

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

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

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]
