An E-4B Airborne Command Post.An E-4B Airborne Command Post. [Source: US Air Force] (click image to enlarge)During the 1980s, top-secret exercises are regularly held, testing a program called Continuity of Government (COG) that would keep the federal government functioning during and after a nuclear war (see 1981-1992). The program includes a special plane called the National Emergency Airborne Command Post (NEACP). This is a modified Boeing 747, based at Andrews Air Force Base, near Washington, DC that has its own conference room and special communications gear. Nicknamed the “Doomsday” plane, it could act as an airborne command post from where a president could run the country during a nuclear war. One of the COG exercises run by the Reagan administration involves a team of officials actually staying aloft in the NEACP for three days straight. The team cruises across the US, and up and down the coasts, periodically being refueled in mid-air. [Schwartz, 1998; Mann, 2004, pp. 144] Dick Cheney and Donald Rumsfeld participate in the COG exercises, though whether they are aboard the NEACP in this particular one is unknown. [Atlantic Monthly, 3/2004] The plan that is being rehearsed for in the exercises will be activated in response to the 9/11 attacks (see (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001). Also on 9/11, three Doomsday planes (then known as “National Airborne Operations Center” planes) will be in the air, due to an exercise taking place that morning called Global Guardian (see Before 9:00 a.m. September 11, 2001).

Many aircraft at Andrews Air Force Base, which is just a few miles outside Washington, DC, are taking part in training exercises. James Ampey, an FAA air traffic controller who is currently on duty in the control tower at the base, will later recall that there are “an unusually high number of aircraft taking off and landing at Andrews [this] morning, because previously scheduled military exercises [are] underway.” [9/11 Commission, 7/28/2003 pdf file] It is unclear what specific exercises these aircraft are participating in, and the exact time period Ampey is referring to.
Militarized 747 Involved in 'Global Guardian' Exercise - According to journalist and author Dan Verton, around the time of the Pentagon attack, “civilian and military officials [are] boarding a militarized version of a Boeing 747, known as the E-4B National Airborne Operations Center (NAOC), at an airfield outside of the nation’s capital. They [are] preparing to conduct a previously scheduled Defense Department exercise” (see (9:27 a.m.) September 11, 2001). [Verton, 2003, pp. 143-144] This airfield is Andrews Air Force Base and the exercise being referred to is the US Strategic Command’s annual exercise, Global Guardian, for which three E-4Bs are launched (see 8:30 a.m. September 11, 2001 and Before 9:00 a.m. September 11, 2001). [Omaha World-Herald, 2/27/2002; Flying K, 9/7/2012 pdf file] Whether other aircraft that are taking off or landing at Andrews are participating in Global Guardian is unknown.
NORAD Exercise, 'Vigilant Guardian' - Another major exercise taking place this morning is called Vigilant Guardian. All of the North American Aerospace Defense Command (NORAD) is participating in it (see (6:30 a.m.) September 11, 2001). [Newhouse News Service, 1/25/2002; Aviation Week and Space Technology, 6/3/2002] However, Andrews is not one of NORAD’s seven “alert” sites around the US. [Airman, 12/1999] And the 113th Wing of the District of Columbia Air National Guard, which is based at Andrews, is not part of the NORAD air defense force. [Aviation Week and Space Technology, 9/9/2002; Filson, 2003, pp. 76] Furthermore, members of the 113th Wing have just returned from a major training exercise in Nevada (see Late August-September 8, 2001), and so, with only a few pilots and planes available, today is a “light flying day” for their unit. [9/11 Commission, 3/11/2004 pdf file] Presumably the 113th Wing is therefore not currently participating in Vigilant Guardian or any other major exercises.
Numerous Units at Andrews - There are, however, many units at Andrews that may be participating in exercises. Among more than 60 separate organizations located at the base are units from the Army, Navy, Marine Corps, Air Force Reserve, and Air National Guard. [DC Military (.com), 6/2001; GlobalSecurity (.org), 1/21/2006] These units include Marine Fighter Attack Squadron 321 (VMFA-321), which flies the F/A-18 Hornet fighter jet, and Naval Air Facility, Washington, DC, which has numerous aircraft available, including the F/A-18 Hornet. [DC Military (.com), 2/9/2001; DC Military (.com), 6/2001]
Andrews Units Respond to Attacks - DC Air National Guard fighters will later take off from Andrews to protect Washington in response to the morning’s attacks (see (10:38 a.m.) September 11, 2001, 10:42 a.m. September 11, 2001, and 11:11 a.m. September 11, 2001). [Aviation Week and Space Technology, 9/9/2002] And a member of VMFA-321 calls NORAD’s Northeast Air Defense Sector (NEADS) at around 9:50 a.m. to offer his unit’s assistance in response to the attacks (see (9:50 a.m.) September 11, 2001).

Offutt Air Force Base control tower during Global Guardian 1998.Offutt Air Force Base control tower during Global Guardian 1998. [Source: Jeffery S. Viano]As the 9/11 attacks are taking place, a large military training exercise called Global Guardian is said to be “in full swing.” It has been going on since the previous week. [Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/10/2002] Global Guardian is an annual exercise sponsored by US Strategic Command (Stratcom) in cooperation with US Space Command and NORAD. One military author defines Stratcom as “the single US military command responsible for the day-to-day readiness of America’s nuclear forces.” [Arkin, 2005, pp. 59]
Exercise Tests Military's Ability to Fight a Nuclear War - Global Guardian is a global readiness exercise involving all Stratcom forces and aims to test Stratcom’s ability to fight a nuclear war. It is one of many “practice Armageddons” that the US military routinely stages. [Bulletin of the Atomic Scientists, 11/1/1997; Associated Press, 2/21/2002; Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/10/2002] It links with a number of other military exercises, including Crown Vigilance (an Air Combat Command exercise), Apollo Guardian (a US Space Command exercise), and the NORAD exercises Vigilant Guardian and Amalgam Warrior. [US Department of Defense, 5/1997; GlobalSecurity (.org), 4/27/2005] Global Guardian is both a command post and a field training exercise, and is based around a fictitious scenario designed to test the ability of Stratcom and its component forces to deter a military attack against the US. Hundreds of military personnel are involved. [US Congress, n.d.; Collins Center Update, 12/1999 pdf file; Times-Picayune, 9/8/2002] The exercise involves “a lot of the elements of what ultimately would be the nuclear command and control system in support of a national emergency,” according to Admiral Richard Mies, the commander in chief of Stratcom. It includes an “exercise secretary of defense” and “an exercise president.” Mies will say that because of the exercise, “A lot of [Stratcom’s] command and control systems that, in peacetime, are normally not on alert were at a much, much higher state of alert [on September 11] and we had a number of aircraft, manned control aircraft that were airborne that were simulating their wartime roles.” [NET News, 12/27/2011]
Exercise Normally Held in October or November - According to a 1998 Internet article by the British American Security Information Council—an independent research organization—Global Guardian is held in October or November each year. [Kristensen, 10/1998] In his book Code Names, NBC News military analyst William Arkin dates this exercise for October 22-31, 2001. [Arkin, 2005, pp. 379] And a military newspaper reported in March 2001 that Global Guardian was scheduled for October 2001. [Space Observer, 3/23/2001, pp. 2 pdf file] If this is correct, then some time after March, the exercise must have been rescheduled for early September.
Exercise Includes a 'Computer Network Attack' - Furthermore, a 1998 Defense Department newsletter reported that for several years Stratcom had been incorporating a computer network attack (CNA) into Global Guardian. The attack involved Stratcom “red team” members and other organizations acting as enemy agents, and included attempts to penetrate the command using the Internet and a “bad” insider who had access to a key command and control system. The attackers “war dialed” the phones to tie them up and sent faxes to numerous fax machines throughout the Command. They also claimed they were able to shut down Stratcom’s systems. Reportedly, Stratcom planned to increase the level of computer network attack in future Global Guardian exercises. [IAnewsletter, 6/1998 pdf file] It is unclear if a computer network attack is incorporated into Global Guardian in 2001.

The US Strategic Command command center.The US Strategic Command command center. [Source: US Strategic Command]At the time the attacks in New York occur, a small group of business leaders are having breakfast at Offutt Air Force Base in Omaha, Nebraska, where the US Strategic Command (Stratcom) is headquartered. With them is Admiral Richard Mies, the commander in chief of Stratcom. They are in town for an annual charity fundraiser event due to take place later in the day, hosted by the multi-billionaire Warren Buffett. Along with other visitors who have come for the fundraiser, they are scheduled to tour the Stratcom underground command center, located 60 feet below Offutt, and receive an unclassified mission briefing. According to the Omaha World-Herald, staff members have left the command center in advance of their visit. It is only after the second attack occurs, at 9:03, that Admiral Mies excuses himself from the breakfast and the battle staff reconvenes in the center. [San Francisco Business Times, 2/1/2002; Omaha World-Herald, 2/27/2002] It is unclear what effect the absence of Mies and the members of the battle staff have upon the military’s ability to respond effectively to the first attacks. However, the command center does have significant capabilities that would, presumably, be of much use under such a crisis. Stratcom is the military command responsible for the readiness of America’s nuclear forces. [Arkin, 2005, pp. 59] The Lincoln Journal Star describes its underground command center as “a military nerve center that collects and assesses information from high-tech ‘eyes and ears’ across—and above—the globe.” [Journal Star (Lincoln), 10/25/2000] The cavernous room has eight giant video screens and complex communications systems. [Associated Press, 2/21/2002; Omaha World-Herald, 2/27/2002] Stratcom itself states that the senior controller in the command center “has a direct line to the National Military Command Center in Washington, DC, and to the other major command headquarters.” This system, called the Joint Chiefs of Staff Alerting Network, allows the commander in chief of Stratcom to make “prompt contact with the president, the secretary of defense, the chairman of the Joint Chiefs of Staff, and other unified commanders.” Furthermore, “Through satellites and radio networks (VLF, LF, UHF and HF), the command center can communicate with aircraft in flight over any part of the world. A principal purpose of these networks is to pass National Command Authority [i.e. the president and secretary of defense] orders to the alert forces.” While only the president can order nuclear strikes, the commander in chief of Stratcom “can launch aircraft for survival.” [United States Strategic Command, 6/22/2001] With the command center’s sophisticated capabilities, after Mies returns to it from his breakfast, the eight video screens there are “loaded up with data,” providing him with “the latest information on the unfolding drama.” [Omaha World-Herald, 2/27/2002] And at the time President Bush arrives at Offutt, later in the day (see 2:50 p.m. September 11, 2001), the battle staff in the center will reportedly be “watching the skies over the United States” and “tracking a commercial airliner on its way from Spain to the United States.” [Washington Post, 1/27/2002; CBS News, 9/11/2002]

The hole caused by the Flight 11 crash.The hole caused by the Flight 11 crash. [Source: Reuters]Flight 11 slams into the WTC North Tower (Building 1). Hijackers Mohamed Atta Waleed Alshehri, Wail Alshehri, Abdulaziz Alomari, and Satam Al Suqami presumably are killed instantly, and many more in the tower will die over the next few hours. Seismic records pinpoint the crash at 26 seconds after 8:46 a.m. [CNN, 9/12/2001; New York Times, 9/12/2001; North American Aerospace Defense Command, 9/18/2001; USA Today, 12/20/2001; Federal Emergency Management Agency, 5/1/2002, pp. 1-10; New York Times, 5/26/2002; USA Today, 8/13/2002; 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.

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

Carl Truscott.Carl Truscott. [Source: ASERO Worldwide]Carl Truscott, the Secret Service special agent in charge of the presidential protective division (PPD), sees coverage of the plane crash at the World Trade Center on television, and calls several colleagues to his office for a meeting to discuss how to respond to the crisis. [United States Secret Service, 10/1/2001] Truscott is responsible for the overall security of the president, the first family, and the White House. [United States Secret Service, 4/1/2004 pdf file] He is in his office at the Eisenhower Executive Office Building, which is located next to the West Wing of the White House and is where most of the president’s staff works. Truscott will later recall that he has “observed the CNN broadcast of the aircraft crashing into the World Trade Center.” [United States Secret Service, 10/1/2001; WBKO, 12/19/2007; 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). [Observer, 9/16/2001; 9/11 Commission, 7/24/2004, pp. 289]

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).

Admiral Richard Mies.
Admiral Richard Mies. [Source: Public domain]Offutt Air Force Base, near Omaha, Nebraska, appears to be the headquarters of the US Strategic Command (Stratcom) exercise Global Guardian that is “in full swing” when the 9/11 attacks begin (see 8:30 a.m. September 11, 2001). At least the director of the exercise, Admiral Richard Mies, commander in chief of Stratcom, is at Offutt this morning. Because of Global Guardian, bombers, missile crews, and submarines around America are all being directed from Stratcom’s command center, a steel and concrete reinforced bunker below Offutt. [Bulletin of the Atomic Scientists, 11/12/1997; Associated Press, 2/21/2002; Omaha World-Herald, 2/27/2002; BBC, 9/1/2002; Omaha World-Herald, 9/10/2002] This bunker is staffed with top personnel and they are at a heightened security mode because of the exercise. [Associated Press, 2/21/2002; Air Force Weather Observer, 7/2002 pdf file]
'Doomsday' Planes Airborne for Exercise - Because of Global Guardian, three special military command aircraft with sophisticated communications equipment, based at Offutt, are up in the air this morning (see (9:27 a.m.) September 11, 2001, Shortly After 9:37 a.m. September 11, 2001, and (9:45 a.m.) September 11, 2001). These E-4B National Airborne Operations Center planes—nicknamed “Doomsday” planes during the Cold War—are intended to control nuclear forces from the air in times of crisis. They are capable of acting as alternative command posts for top government officials from where they can direct US forces, execute war orders, and coordinate the actions of civil authorities in times of national emergency. The federal advisory committee, whose chairman is retired Lieutenant General Brent Scowcroft, is aboard one of these Doomsday planes, being brought to Offutt to observe the exercise (see (Shortly After 9:03 a.m.) September 11, 2001). Global Guardian will reportedly be put on pause at 9:11 a.m. (see 9:11 a.m. September 11, 2001), but not formally terminated until 10:44 a.m. (see (10:44 a.m.) September 11, 2001), and the battle staff at Offutt will switch to “real-world mode” once the attacks are apparent. However, even after Global Guardian is called off, the three E-4Bs will remain airborne. Also this morning, a small group of business leaders are at Offutt because of a charity fundraiser event due to take place later in the day, hosted by the multi-billionaire Warren Buffett (see (8:45 a.m.-9:03 a.m.) September 11, 2001).

Thomas Keck.Thomas Keck. [Source: US Air Force]When Lieutenant General Thomas Keck, the commander of the 8th Air Force at Barksdale Air Force Base in Louisiana, is told that a plane has crashed into the World Trade Center, he mistakenly thinks this is a simulated scenario as part of a training exercise. [2d Bomb Wing, 6/30/2002, pp. 40 pdf file; American History, 10/2006 pdf file] Barksdale is one of a number of Air Force bases where aircraft and personnel are currently participating in the exercise Global Guardian (see 8:48 a.m. September 11, 2001). [Times-Picayune, 9/8/2002] This annual exercise is run by the US Strategic Command (Stratcom) and aims to test the command’s ability to fight a nuclear war (see 8:30 a.m. September 11, 2001). [Bulletin of the Atomic Scientists, 11/1/1997; Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/8/2002; GlobalSecurity (.org), 4/27/2005]
Keck Thinks Crash Is a 'Scenario Injection' - Keck is sitting in a windowless command center at Barksdale, monitoring the base’s participation in Global Guardian. Ground crews are practicing getting a fleet of B-52 bombers fueled, armed, and ready to get airborne for bombing runs. Keck watches on a monitor as, at exactly 9:00 a.m., an alarm sounds across the base and the crews rush to their planes. Then a younger officer taps him on the shoulder and tells him, “Sir, we just had an aircraft hit the World Trade Center.” Keck mistakenly thinks the officer is describing a simulated crisis that is being included in the exercise. He says: “That’s not the way you interject a situation into a training exercise! When you have a scenario injection, you say, ‘Sir, this is an exercise input,’ and then you give me the information.” But the younger officer replies, “No, sir,” and points at a television showing CNN, which is broadcasting live coverage of the burning WTC in New York.
Keck Thinks First Crash Is an Accident - Keck’s initial thought upon seeing the TV coverage is reportedly, “How could such a terrible accident happen?” It is only when Keck sees the second plane hitting the WTC at 9:03 a.m. that he will realize the US is under attack. He then yells to his staff, “Lock it down,” thereby signaling that the exercise is over. [American History, 10/2006 pdf file] (However, according to an article in The Bombardier, the newspaper for Barksdale Air Force Base, Stratcom will put Global Guardian on pause at 9:11 a.m. (see 9:11 a.m. September 11, 2001), but only terminate the exercise at 10:44 a.m. (see (10:44 a.m.) September 11, 2001). [Bombardier, 9/8/2006 pdf file] ) After seeing the second crash, Keck will leave the command center from where he has been monitoring the exercise and go to the 8th Air Force battle staff, to be briefed on reports coming from Air Force headquarters about the ongoing terrorist attacks. He will later on accompany President Bush while he is at Barksdale, after landing there on Air Force One at about 11:45 a.m. (see 11:45 a.m. September 11, 2001). [American History, 10/2006 pdf file]

An announcement is made over the public address system in the South Tower of the World Trade Center, advising workers that they can begin an orderly evacuation of the building if conditions warrant it. [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.

Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter.Flight 175 hits the WTC South Tower. The picture was taken from a traffic helicopter. [Source: WABC 7/ Salient Stills]Flight 175 hits the South Tower of the World Trade Center (Tower Two). Seismic records pinpoint the time at six seconds before 9:03 a.m. (rounded to 9:03 a.m.). Hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, Mohand Alshehri, Hamza Alghamdi, and Ahmed Alghamdi presumably are killed instantly, and many more in the tower will die over the next few hours. [New York Times, 9/12/2001; CNN, 9/12/2001; CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; 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).

Mark Pillar.Mark Pillar. [Source: US Air Force]Senior officers at Offutt Air Force Base in Nebraska hear incorrect reports about terrorist acts that have not actually happened, which they promptly look into. Brigadier General Mark Pillar and other senior officers at Offutt agreed that the US was under attack when they saw the second hijacked plane crashing into the World Trade Center on television, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). At that time, Pillar will later comment, “It was organized chaos, because there was so much we didn’t know.” Subsequently, he and other high-ranking officers at the base hear “rumors or suspicions” of possible terrorist activities, which turn out to be untrue. These alleged activities involve such things as “anthrax-carrying planes, the poisoning of drinking water supplies, and numerous bomb threats, from the Transamerica building in San Francisco to the John Hancock Tower in Boston,” Pillar will recall. Pillar and other senior officers “immediately” launch investigations into these rumors. The exact time at which these incorrect reports start being received is unstated. [Columbus Republic, 10/27/2016] Offutt Air Force Base is home to the US Strategic Command (Stratcom), which controls America’s nuclear weapons. [Associated Press, 9/11/2001] Personnel there were in the middle of a major training exercise called Global Guardian, which theorized that a rogue nation would attack the US with nuclear weapons, when the attacks began this morning (see 8:30 a.m. September 11, 2001 and Before 9:00 a.m. September 11, 2001). [Omaha World-Herald, 9/8/2002; Schmitt and Shanker, 2011, pp. 22; NET News, 12/27/2011] Air Force One, with President Bush on board, will land at Offutt at 2:50 p.m. this afternoon (see 2:50 p.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).

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

The US Strategic Command (Stratcom) orders that its Global Guardian exercise be put on pause at this time, according to a 2006 article in The Bombardier, the newspaper for Barksdale Air Force Base, Louisiana. [Bombardier, 9/8/2006 pdf file] Global Guardian is an annual exercise sponsored by Stratcom, which has its headquarters at Offutt Air Force Base, Nebraska. The exercise tests Stratcom’s ability to fight a nuclear war (see 8:30 a.m. September 11, 2001).

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).

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]

Fox News correspondent Brian Wilson will later recall that when reporting from the Capitol building around this time, he is “talking about the first lady being in the Capitol and saying that I had not seen any signs of tighter security in the building.”

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).

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).

According to former counterterrorism “tsar” Richard Clarke, around this time the acting Chairman of the Joint Chiefs of Staff Richard Myers speaks to him via video link (see 9:28 a.m. September 11, 2001). During their conversation, Myers mentions, “We are in the middle of Vigilant Warrior, a NORAD exercise.” [Clarke, 2004, pp. 5] However, no other references have been found to this exercise, “Vigilant Warrior.” Considering that exercise terms are “normally an unclassified nickname,” [Chairman of the Joint Chiefs of Staff, 4/23/1998 pdf file] this is perhaps a little odd. Could Richard Clarke have mistakenly been referring to the Vigilant Guardian exercise (see (6:30 a.m.) September 11, 2001), which is taking place on 9/11? According to a later news report though, NORAD confirms that “it was running two mock drills on Sept. 11 at various radar sites and Command Centers in the United States and Canada,” one of these being Vigilant Guardian. [New Jersey Star-Ledger, 12/5/2003] If this is correct then there must be another NORAD exercise on 9/11. If not “Vigilant Warrior,” a possibility is that the exercise referred to by Richard Clarke is in fact “Amalgam Warrior,” which is a NORAD-sponsored, large-scale, live-fly air defense and air intercept field training exercise. Amalgam Warrior usually involves two or more NORAD regions and is held twice yearly, in the spring for the West Coast and in the autumn for the East Coast. [US Congress, n.d.; Airman, 1/1996; Arkin, 2005, pp. 254; GlobalSecurity (.org), 4/27/2005] Is it possible that in 2001 the East Coast Amalgam Warrior is being held earlier than usual (like Global Guardian (see 8:30 a.m. September 11, 2001)) and is taking place on 9/11? In support of this possibility is a 1997 Defense Department report that describes the Stratcom exercise Global Guardian, saying it “links with other exercise activities sponsored by the Chairman, Joint Chiefs of Staff, and the Unified Commands.” The exercises it links with are Crown Vigilance (an Air Combat Command exercise), Apollo Guardian (a US Space Command exercise), and—significantly—the NORAD exercises Vigilant Guardian and Amalgam Warrior. [US Department of Defense, 5/1997; GlobalSecurity (.org), 4/27/2005] Since in 2001, Vigilant Guardian (see (6:30 a.m.) September 11, 2001) is occurring the same time as Global Guardian, might Amalgam Warrior be as well? In his book Code Names, William Arkin says that Amalgam Warrior is “sometimes combined with Global Guardian.” [Arkin, 2005, pp. 254] Amalgam Warrior tests such activities as tracking, surveillance, air interception, employing rules of engagement, attack assessment, electronic warfare, and counter-cruise-missile operations. A previous Amalgam Warrior in 1996 involved such situations as tracking unknown aircraft that had incorrectly filed their flight plans or wandered off course, in-flight emergencies, terrorist aircraft attacks, and large-scale bomber strike missions. Amalgam Warrior 98-1 was NORAD’s largest ever exercise and involved six B-1B bombers being deployed to Eielson Air Force Base, Alaska, to act as an enemy threat by infiltrating the aerial borders of North America. [Airman, 1/1996; Arkin, 2005, pp. 254; GlobalSecurity (.org), 4/27/2005] Another Amalgam Warrior in fall 2000 similarly involved four B-1 bombers acting as enemy forces trying to invade Alaska, with NORAD going from tracking the unknown aircraft to sending up “alert” F-15s in response. [Eielson News Service, 10/27/2000; Associated Press, 10/29/2000] If either one (or both) of these exercises ending with the name “Warrior” is taking place on 9/11, this could be very significant, because the word “Warrior” indicates that the exercise is a Joint Chiefs of Staff-approved, Commander in Chief, NORAD-sponsored field training exercise. [North American Aerospace Defense Command, 8/25/1989] Real planes would be pretending to be threats to the US and real fighters would be deployed to defend against them.

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). [9/11 Commission, 5/18/2004 pdf file; National Institute of Standards and Technology, 9/2005, pp. 109]

Bill Grimes.Bill Grimes. [Source: Lori A. Bultman / US Air Force]Colonel Bill Grimes receives a call in which he is asked about getting the Predator drone, a remotely controlled, unmanned plane, ready to fly over Afghanistan. [Whittle, 2014, pp. 235] Grimes is the director of Big Safari, a highly secretive Air Force program based at Wright-Patterson Air Force Base in Ohio that specializes in modifying standard Air Force aircraft for time-sensitive and highly classified operations. [Defense Update, 5/3/2013; Wired, 12/17/2015] He was in his office at Wright-Patterson this morning when a colleague told him an airplane had crashed into the World Trade Center. He then joined others watching the television coverage of the incident in the conference room next to his office and saw the second hijacked plane crashing into the WTC, at 9:03 a.m. (see 9:03 a.m. September 11, 2001). “Within a few minutes” of the second crash, according to journalist and author Richard Whittle, Grimes is called back to his office to take a call from Lieutenant Colonel Kenneth Johns, who is at Air Force headquarters at the Pentagon. Johns wants to know what needs to be done to get three Predators, and whatever is needed to fly them over Afghanistan, ready to go. But just as the two men start discussing the matter, Johns says he will have to call again later, since the Pentagon is being evacuated. This evacuation is presumably in response to the attack on the Pentagon, which occurs at 9:37 a.m. (see 9:37 a.m. September 11, 2001). Grimes says he will have answers by the time the two men talk again. [Whittle, 2014, pp. 235] He will subsequently call members of his team, and tell them to pack their bags and prepare to deploy. He will instruct them to go to the airfield at Palmdale, California, where a C-17 cargo plane will arrive soon to pick them up. Grimes will later write that he starts calling the members of his team “[m]ere moments after the second airliner crashed into the World Trade Center.” According to Whittle, he starts making the calls “shortly after” the second crash at the WTC. However, if his conversation with Johns occurs around the time of the Pentagon attack, he presumably only starts calling the members of his team after 9:37 a.m. A C-17 will set off tomorrow to fly three Predators, along with members of Grimes’s team, from California to Washington, DC (see September 12-14, 2001).

Minutes after the attack on the Pentagon, an E-4B National Airborne Operations Center plane takes off from Wright-Patterson Air Force Base, near Dayton, Ohio, bound for an undisclosed location. E-4Bs are highly modified Boeing 747s, fitted with sophisticated communications equipment, that act as flying military command posts. Nicknamed “Doomsday” planes during the Cold War, they serve the president and the Joint Chiefs of Staff. They can also support the Federal Emergency Management Agency (FEMA) during major disasters, like hurricanes or earthquakes. Wright-Patterson is one of the few designated bases for these special planes. The US military possesses four of them in total, one of which is constantly kept on alert. [Federation of American Scientists, 4/23/2000; Dayton Daily News, 9/12/2001] Three of the E-4Bs are airborne this morning, due to their role in a pre-scheduled military exercise called Global Guardian (see Before 9:00 a.m. September 11, 2001, (9:27 a.m.) September 11, 2001, and (9:45 a.m.) September 11, 2001).

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

Alice Hoglan, the mother of Mark Bingham, a passenger on Flight 93, informs the FBI that her son has just phoned her from the plane, and then calls Bingham’s cell phone and leaves two voicemail messages. [Federal Bureau of Investigation, 9/17/2001; Barrett, 2002, pp. 157-158] Alice Hoglan is currently staying at the home of her brother, Vaughn Hoglan, and his wife in Saratoga, California. [Longman, 2002, pp. 129; San Francisco Chronicle, 9/10/2003] Bingham has just called her and told her his flight was taken over by three men who said they had a bomb, but the call got broken off after less than three minutes (see (9:37 a.m.) September 11, 2001). [Federal Bureau of Investigation, 9/11/2001; 9/11 Commission, 5/13/2004 pdf file; 9/11 Commission, 8/26/2004, pp. 41, 99]
Bingham's Mother Realizes Flight 93 Will Likely Crash - No one in the Hoglan household was aware of the terrorist attacks in New York and at the Pentagon. But after the call from Bingham ends, Vaughn Hoglan switches on the television to see if there is any news about Flight 93 and the family sees, for the first time, the recorded footage of Flight 175 crashing into the World Trade Center (see 9:03 a.m. September 11, 2001). [BBC, 12/2001; Barrett, 2002, pp. 157] Alice Hoglan then realizes the hijacking of Flight 93 is part of a “grand and ugly scheme,” and that her son’s plane will likely crash, too.

Bingham's Mother Tells the FBI about the Hijacking - Being a flight attendant with United Airlines, she calls her airline to ask about her son’s plane. [Los Gatos Patch, 8/25/2011] However, she will later recall, all she gets is a recorded message, which states, “United Flight 93 left Newark at 8:01 a.m. and will arrive San Francisco, Gate 82, at 11:19 a.m.” [BBC, 12/2001] She also calls 9-1-1 to report what has happened. She is put through to the San Francisco division of the FBI and speaks to an agent there. [Federal Bureau of Investigation, 9/17/2001] The agent asks her a series of questions about the hijackers on Flight 93, but she is unable to answer them.
Bingham's Mother Leaves Messages for Her Son - Alice Hoglan then tries calling her son twice on his cell phone, intending to let him know the full scale of the attack that his plane’s hijacking is part of. On both occasions, she has to leave messages on his voicemail. She makes the first call at 9:54 a.m. (Because she is flustered, she miscalculates the East Coast time by an hour during the call and also mistakenly says Flight 93 might be used as a “target” rather than as a “weapon.”) She says: “Mark, this is your mom. It’s 10:54 a.m. [Eastern Time]. The news is that it’s been hijacked by terrorists. They are planning to probably use the plane as a target to hit some site on the ground. So, if you possibly can, try to overpower these guys if you can, ‘cause they will probably use the plane as a target. I would say go ahead and do everything you can to overpower them, because they’re hellbent. Try to call me back if you can. You know the number here. Okay, I love you sweetie. Bye.” A minute or so later she calls Bingham’s cell phone again and leaves a second, similar message. Among other things, she urges her son to “group some people and perhaps do the best you can to get control of [the plane].” [Barrett, 2002, pp. 157-158; San Jose Mercury News, 9/10/2011; McMillan, 2014, pp. 122] Bingham will never receive these messages. [ABC News, 3/30/2002] His plane will crash in a field in Pennsylvania at 10:03 a.m. (see (10:03 a.m.-10:10 a.m.) September 11, 2001 and (10:06 a.m.) September 11, 2001).

An E-4B National Airborne Operations Center, with the call sign “Venus 77,” takes off from Andrews Air Force Base, near Washington, DC, in response to the attack on the Pentagon. [Federal Aviation Administration, 9/11/2001 pdf file; 9/11 Commission, 2/17/2004; Farmer, 2009, pp. 206] The E-4B is a highly modified Boeing 747, fitted with sophisticated communications equipment, which can serve as a flying military command post during a national emergency. 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). [Farmer, 2009, pp. 372] However, that plane was reported to be “circling the White House” at 9:41 a.m., before Venus 77 takes off. [ABC News, 9/11/2001] Another E-4B, with the call sign “Word 31,” took off from Andrews Air Force Base at around 9:27 a.m. (see (9:27 a.m.) September 11, 2001), so that aircraft might be the “mystery plane” seen flying over Washington.

[Source: White House]President Bush and his staff have difficulty communicating with colleagues in Washington, DC, while they are traveling on Air Force One, after the plane takes off from Sarasota-Bradenton International Airport (see 9:54 a.m. September 11, 2001). [Northwest Indiana Times, 9/22/2002; Canadian Broadcasting Corporation, 9/10/2006; Politico Magazine, 9/9/2016] Bush had problems calling his colleagues at the White House while he was being driven to the airport, after leaving the Emma E. Booker Elementary School in Sarasota, Florida, at around 9:35 a.m. (see (9:34 a.m.-9:43 a.m.) September 11, 2001). [9/11 Commission, 6/17/2004; Canadian Broadcasting Corporation, 9/10/2006]
Air Force One Should Have 'Outstanding Communications' - He ought to have more success after he boards Air Force One, at around 9:45 a.m. (see (9:43 a.m.) September 11, 2001), since the plane has state-of-the-art communications systems. [Inside the White House, 9/1998; Hardesty, 2003, pp. 167] Its capabilities are “just as good as the communications from the Oval Office in terms of [the president] being able to call, in a secure way, the secretary of defense, the secretary of state, the generals that might have to fight a war, or the vice president or… the national security adviser,” White House chief of staff Andrew Card will later comment. The plane has the “capacity to have… outstanding communications,” he will say. [White House, 8/12/2002]
Communications Systems Are 'All Jammed' - However, Bush and his staff have great difficulty sending and receiving information about the day’s events while they are on Air Force One. [Northwest Indiana Times, 9/22/2002] The “multiple [communications] systems—commercial and terrestrial systems” on the plane are “all jammed,” according to Master Sergeant Dana Lark, superintendent of communications. Lark actually wonders, “Did someone sabotage our comms?” [Politico Magazine, 9/9/2016]
Bush Has Problems Communicating with Vice President Cheney - Bush finds that his calls are successful only intermittently. [Canadian Broadcasting Corporation, 9/10/2006] Attempts are made to establish an open line with Vice President Dick Cheney and National Security Adviser Condoleezza Rice, who are at the White House, but the line keeps dropping. [Bush, 2010, pp. 131] “It was absolutely stunning, standing next to the president as he was talking to the vice president, then holding the phone off his ear because it cut off,” White House press secretary Ari Fleischer will comment. [Politico Magazine, 9/9/2016] At one point, Bush pounds his desk in frustration and shouts: “This is inexcusable. Get me the vice president.” [CBS News, 9/11/2002] He also has difficulty reaching his wife, Laura, since the line keeps dropping when he tries to call her. He eventually talks to her shortly before 11:45 a.m., when Air Force One is approaching Barksdale Air Force Base in Louisiana (see (Shortly Before 11:45 a.m.) September 11, 2001). [Bush, 2010, pp. 132]
Officials in Washington Are Unable to Call the Plane - Some key individuals in Washington are unsuccessful when they try calling Air Force One. Scott Heyer, a communications officer in the White House Situation Room, is unable to contact the plane while it is flying from Sarasota to Barksdale Air Force Base, even when he tries calling its satellite phone (see 9:54 a.m.-11:45 a.m. September 11, 2001). [9/11 Commission, 3/16/2004] And White House counselor Karen Hughes is unable to reach the president when she tries calling him while he is airborne (see (Between 10:31 a.m. and 11:45 a.m.) September 11, 2001). [Washington Post, 1/27/2002; NBC, 4/4/2004]
Bush Has His First Teleconference Hours after Leaving Sarasota - As a result of his problems communicating from the plane, Bush will hold his first teleconference with his principal advisers at around 3:15 p.m. (see (3:15 p.m.) September 11, 2001)—more than five hours after he takes off from Sarasota—after he arrives at Offutt Air Force Base in Nebraska, where there is sophisticated communications equipment (see 2:50 p.m. September 11, 2001). [Northwest Indiana Times, 9/22/2002; Business Week, 11/4/2002; 9/11 Commission, 7/24/2004, pp. 326] By that time, the communication problems will apparently have started to ease. Lark will recall that as Air Force One is flying to Offutt, “some of the commercial systems finally began to become available” and she actually receives a call from her chief. [Politico Magazine, 9/9/2016]
Good Communications Are 'Critical' for the President - Bush’s communication problems may have a significant impact on the government’s ability to respond to the terrorist attacks. Thomas Kean, the chairman of the 9/11 Commission, will explain why the president’s ability to communicate during a crisis is so important, saying, “In the case of any kind of attack in the United States, what you’re supposed to do is get the president off the ground and Air Force One then becomes the command center.” Once he is airborne, the president is “commanding the forces of the United States from the air,” Kean will say. [Canadian Broadcasting Corporation, 9/10/2006] “The president literally can’t function in his constitutional role unless he can communicate, so [good communications are] absolutely critical,” Lieutenant Colonel Thomas Herman, a senior presidential communications officer, will similarly comment. [Marist Magazine, 10/2002] The president “is the only one who can give certain orders that need to be given,” Kean will note. [Canadian Broadcasting Corporation, 9/10/2006] However, Mark Rosenker, director of the White House Military Office, will claim that the communication problems have only a limited impact. “[F]or the most part I believe the president had the ability to do what was necessary to be in control and have command of his forces, and talk with his national security structure,” he will say. [White House, 8/29/2002]
Communications Systems Are Supposedly 'Saturated' - Lark will learn at a later date that the communication problems occur because, she will say, “the commercial systems were all just saturated.” [Politico Magazine, 9/9/2016] Rosenker will similarly suggest that the problems may be partly due to the fact that communications from Air Force One “have to get through a regular telephone network,” and when there is a crisis, the increased volume of communications “jam and overuse the structure.” [White House, 8/29/2002] On top of their problems making and receiving calls, Bush and his staffers have difficulty monitoring the television coverage of the attacks while they are airborne, because the reception on the plane is poor and intermittent (see (9:54 a.m.-6:54 p.m.) September 11, 2001).

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

[Sammon, 2002, pp. 106-107; Woodward, 2002, pp. 18; CBS News, 9/11/2002] The White House has just received an anonymous phone call in which the caller said the president’s plane would be the next terrorist target (see (10:30 a.m.) September 11, 2001). [Woodward, 2002, pp. 18; 9/11 Commission, 7/24/2004, pp. 554] The caller referred to the plane as “Angel,” which is the Secret Service’s code name for Air Force One. [Fleischer, 2005, pp. 141-142] Details of the call were passed on to government officials, including Cheney, in the Presidential Emergency Operations Center (PEOC) below the White House. [White House, 11/19/2001; Newsweek, 12/30/2001; 9/11 Commission, 7/24/2004, pp. 554]
Cheney Tells Bush about a 'Credible' Threat - Cheney now tells Bush: “We’re getting reports of a threat against you. It appears credible,” Major Robert Darling of the White House Military Office, who is with Cheney in the PEOC, will later recall. Cheney says, “We’re scrambling fighter escorts and the Secret Service is taking internal precautions on board Air Force One.” [Darling, 2010, pp. 61] Bush turns to Lieutenant Colonel Thomas Gould, his military aide, and passes on the news, saying, “A call came into the White House switchboard saying, ‘Angel is next.’” Bush then continues talking with Cheney and says, “We’re at war, Dick, and we’re going to find out who did this and we’re going to kick their ass.” [Sammon, 2002, pp. 107; Fleischer, 2005, pp. 141-142]
Pilot Is Told of the Threat and Asks for a Guard at the Cockpit Door - Colonel Mark Tillman, the pilot of Air Force One, is told about the threat. [CBS News, 9/11/2002] Noting that “Angel” is “a classified call sign of Air Force One,” Tillman will comment that “the only people that knew that call sign was us, [the] Secret Service, and the staff.” Therefore, he will say, “for somebody [to] call into the White House and say that Angel was next, that was just incredible.” [US Air Force, 2/29/2012 pdf file] “It was serious before that, but now… no longer is it a time to get the president home,” Tillman will comment. “We actually have to consider everything we say. Everything we do could be intercepted and we have to make sure that no one knows what our position is.” Tillman asks to have an armed guard at his cockpit door. Will Chandler, the chief of security, is therefore summoned to the front of the plane and stands watch at the base of the stairs leading to the cockpit. No one is then allowed up these stairs. Secret Service agents double-check the identity of everyone on the plane, while the crew reviews the emergency evacuation plan. [CBS News, 9/11/2002; Politico Magazine, 9/9/2016]
Threat Influences the Decision to Fly to Nebraska - White House press secretary Ari Fleischer, who is on Air Force One with Bush, will say the threat against the president’s plane is what leads to the decision to take Bush to Offutt Air Force Base in Nebraska (see 2:50 p.m. September 11, 2001) and is also one of the reasons why Bush does not head back to Washington, DC, right away. [White House, 9/12/2001] However, during the afternoon, the Secret Service will determine that the reported threat was unfounded. [9/11 Commission, 7/24/2004, pp. 554] Shortly after Bush learns about the threat, Tillman will be informed that an aircraft that may have been hijacked is heading toward Air Force One (see (10:35 a.m.) September 11, 2001). [CBS News, 9/11/2002; CBS News, 1/17/2009] White House chief of staff Andrew Card will say he in fact learned a threat had been made against Air Force One almost an hour earlier, while he was being driven with Bush to Sarasota-Bradenton International Airport (see (Between 9:35 a.m. and 9:43 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).

Doug Lomheim.Doug Lomheim. [Source: US Air Force]An Airborne Warning and Control System (AWACS) plane takes off from Tinker Air Force Base in Oklahoma and subsequently accompanies Air Force One as it makes its way back to Washington, DC, after leaving Barksdale Air Force Base in Louisiana. [Air Force Print News, 9/9/2011; Kennedy et al., 2012, pp. 61] An AWACS, also called the E-3 Sentry, is a modified Boeing 707 that provides surveillance, command, control, and communications to military commanders. [New York Times, 9/23/1995; GlobalSecurity (.org), 4/16/2006; US Air Force, 9/22/2015] The AWACS that scrambles from Tinker Air Force Base is apparently piloted by Air Force reservists Major Doug Lomheim and Captain Greg Miller. The two men had been preparing for a student training sortie on their E-3 early this morning but then learned of the crashes at the World Trade Center during a delay due to one of the plane’s engines failing to start. After being told they would be assigned to do something in response to the terrorist attacks, they sent their students back to the training squadron and gathered their “NORAD material.” Lomheim and Miller take off from Tinker Air Force Base at around midday and check in with NORAD’s Southeast Air Defense Sector (SEADS). SEADS instructs them to head to Barksdale Air Force Base, where Air Force One, with President Bush on board, recently landed (see 11:45 a.m. September 11, 2001). “We want you to escort [Bush] wherever he goes,” they are told. Their plane goes into an orbit over western Louisiana while Bush is at Barksdale. They then accompany Air Force One after it leaves the base (see 1:37 p.m. September 11, 2001) and orbit overhead after it lands at Offutt Air Force Base in Nebraska (see 2:50 p.m. September 11, 2001). They continue following the president’s plane after it takes off from Offutt and heads toward Washington (see (4:33 p.m.) September 11, 2001). [Air Force Print News, 9/9/2011; Kennedy et al., 2012, pp. 61] An AWACS plane that had been flying a training mission was instructed to accompany Air Force One earlier on, after it took off from Sarasota, Florida (see Before 9:55 a.m. September 11, 2001). Whether that plane is escorting Air Force One while Lomheim and Miller’s plane follows it is unclear. [Filson, 2003, pp. 86-87]

[GlobalSecurity (.org), 1/21/2006]
SEADS Scrambles Fighters - Although the wing is not one of NORAD’s alert units around the US, NORAD’s Southeast Air Defense Sector (SEADS) scrambles four of its fighters around the time President Bush is leaving Barksdale Air Base on board Air Force One (see 1:37 p.m. September 11, 2001). The fighters had already been loaded with live missiles by the time Air Force One landed at the base (see 11:45 a.m. September 11, 2001). According to weapons officer Major Jeff Woelbling, “As we were all watching the news, the wing leadership decided to configure our jets and get ready.”
Military Unaware of Air Force One's Route - At the time Air Force One leaves Barksdale, SEADS is unaware of its next destination. Lieutenant Colonel Randy Riccardi, the commander of the 122nd Fighter Squadron, which is part of the 159th Fighter Wing, will later recall, “When Air Force One took off out of Barksdale, we were scrambled because SEADS didn’t know his route of flight.” Riccardi will add: “We were in a four-ship and turned north toward Barksdale and the president was already airborne. We were 300 miles behind him since SEADS didn’t know where he was going.” The 159th Fighter Wing jets will accompany Air Force One until it is near Offutt Air Force Base, Nebraska (see 2:50 p.m. September 11, 2001). They then turn around and return to base. [Filson, 2003, pp. 87] When Air Force One landed at Barksdale, it was already being escorted by jets from the 147th Fighter Wing of the Texas Air National Guard (see (After 9:56 a.m.) September 11, 2001 and (11:29 a.m.) September 11, 2001). Those jets will continue escorting the president’s plane until it reaches Washington, DC. [Galveston County Daily News, 7/9/2005; Bombardier, 9/8/2006 pdf file]

President Bush asks Mike Morell, his CIA briefer, who is responsible for today’s attacks on the US and Morell says he is sure al-Qaeda is to blame. About 15 minutes after Air Force One left Barksdale Air Force Base (see 1:37 p.m. September 11, 2001), White House chief of staff Andrew Card enters the staff section of the plane, where Morell is seated, and tells Morell that the president wants to see him. Morell goes to Bush’s office, where he then sits alone with the president and Card.
CIA Briefer Says He'd Bet Al-Qaeda Was behind the Attacks - Bush wants to know who Morell thinks is responsible for today’s attacks. “Michael, who did this?” he asks. Morell explains that he doesn’t have any intelligence indicating who is to blame, so he will simply provide his personal opinion. “I said that there were two countries capable of carrying out an attack like this, Iran and Iraq, but I believed both would have everything to lose and nothing to gain from the attack,” he will later recall. The culprit was almost certainly a non-state actor, he says, adding that he has no doubt that the trail of evidence will lead to the doorstep of Osama bin Laden and al-Qaeda. “I’d bet my children’s future on that,” he says.
Briefer Is Unsure How Long It Will Take to Determine Who Is Responsible - “When will we know?” Bush asks. Morell replies, “I can’t say for sure,” and then goes over some recent terrorist attacks and says how long it took the CIA to determine, with any certainty, who was responsible. He says that in the case of the 1998 bombings of the US embassies in Kenya and Tanzania (see 10:35-10:39 a.m., August 7, 1998), it took a couple of days; with the bombing of the USS Cole in Yemen in 2000 (see October 12, 2000), it took a couple of months; but with the 1996 bombing of the Khobar Towers in Saudi Arabia (see June 25, 1996), it had taken over a year. He says the CIA may know soon who is to blame for today’s attacks, but then again it might take some time. Bush says nothing in response once Morell has finished giving his views on who is responsible for today’s attacks and the men sit in silence for a while. Finally, Morell asks, “Is there anything else, Mr. President?” and Bush replies, “No, Michael, thank you.” Morell then returns to his seat in the staff section of the plane. [Studies in Intelligence, 9/2006 pdf file; Morell and Harlow, 2015, pp. 55-56; Politico Magazine, 9/9/2016] Bush will learn that the CIA has linked al-Qaeda to today’s attacks later this afternoon, after Air Force One lands at Offutt Air Force Base in Nebraska (see 2:50 p.m. September 11, 2001). During a video teleconference, CIA Director George Tenet will tell him that early signs indicate the terrorist group is behind the attacks (see (3:15 p.m.) September 11, 2001).

[Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/8/2002; Omaha World-Herald, 9/9/2016] They have, however, taken the initiative to start preparing for his arrival. “There were pretty wide-scale preparations going on anticipating that the president might come, without knowing for sure, even before we got notice that he was coming,” Admiral Richard Mies, commander in chief of Stratcom, will later recall. “We’d started to evacuate the main quarters that could be used for VIPs and install some of the protection there that’d be needed in case [Bush] needed to spend the night,” Mies will say. [NET News, 12/27/2011; Politico Magazine, 9/9/2016] Journalists on Air Force One were not told they would be landing at Offutt.

President Bush gets off Air Force One and is taken to a command center several stories underground at Offutt Air Force Base in Nebraska. [Salon, 9/12/2001; Bamford, 2004, pp. 89] At 2:50 p.m., the president’s plane landed at Offutt, home of the US Strategic Command (Stratcom), which controls America’s nuclear weapons (see 2:50 p.m. September 11, 2001). [Associated Press, 9/11/2001; 9/11 Commission, 7/24/2004, pp. 326] About 10 minutes later, Bush emerges from the plane. [Salon, 9/12/2001] Admiral Richard Mies, commander in chief of Stratcom, along with a driver and a Secret Service agent, has come in a car to meet Air Force One on the runway. After getting off the plane, Bush gets into the back of the car with Mies. [Sammon, 2002, pp. 121; NET News, 12/27/2011; Politico Magazine, 9/9/2016] His staffers, meanwhile, get onto buses. [Studies in Intelligence, 9/2006 pdf file] The vehicles are driven away from the plane and across the large base. [Sammon, 2002, pp. 121]
Bush Goes to the Underground Command Center - Bush and his staffers are then taken to Stratcom’s underground command center. [CBS News, 9/2/2003] They are taken by Mies through the center’s fire escape in order to reach it. [NET News, 12/27/2011; Omaha World-Herald, 9/9/2016] They are driven to a small, concrete building, resembling a hut, go through a door in it, and then head down a staircase. [White House, 8/12/2002; Fleischer, 2005, pp. 147-148] “We went down and down and down, pretty far underground,” Brian Montgomery, the White House’s director of advance, will later recall. [Politico Magazine, 9/9/2016] “It’s a long way down,” Karl Rove, Bush’s senior adviser, will describe, “and then you emerge and go through a series of hallways and special doors, blast doors… and then you enter into a conference center, which is… several stories underground.” [ABC News, 9/11/2002]
Exercise Means Extra People Are in the Command Center - The command center, according to author James Bamford, is “a cavernous two-story war room with banks of dark wooden desks curved away from a giant projection screen on which [is] displayed the status of military forces around the world.” [Bamford, 2004, pp. 89] Eight giant video screens are loaded with data and numerous military personnel are seated at computer terminals that are hooked into satellites monitoring activities around the world. [Washington Post, 1/27/2002; Omaha World-Herald, 2/27/2002] Stratcom was in the middle of a major training exercise, called Global Guardian, when the attacks began this morning (see 8:30 a.m. September 11, 2001 and Before 9:00 a.m. September 11, 2001) and consequently many more people are in the command center than would normally be there.
Bush Is Briefed on the Attacks - When Bush enters, Rear Admiral Jay Donnelly, the operations officer in the center, announces, “Ladies and gentlemen, the president.” Everyone comes to attention. Bush then tells them to sit down. Mies gives Bush a briefing in the command center. “The president sat down and I briefed him on what each of [the] screens was displaying,” he will recall, adding, “Gave him, as best I could, an update from [Stratcom’s] perspective of what was happening based on what we knew.” [Omaha World-Herald, 9/8/2002; NET News, 12/27/2011] After being briefed, Bush and Andrew Card, his chief of staff, will be taken to a teleconference center.

President Bush takes part in a video teleconference at Offutt Air Force Base. Chief of Staff Andrew Card sits on his left, and Admiral Richard Mies sits on his left. [Source: White House]At Offutt Air Force Base in Nebraska, President Bush convenes the first meeting of the National Security Council since the attacks occurred. [Woodward, 2002, pp. 26] He begins the video conference call from a bunker beneath the base. He and Chief of Staff Andrew Card visually communicate directly with Vice President Cheney, National Security Adviser Rice, Defense Secretary Rumsfeld, Deputy Secretary of State Richard Armitage, CIA Director Tenet, Transportation Secretary Norman Mineta, counterterrorism “tsar” Richard Clarke, and others. [Daily Telegraph, 12/16/2001; ABC News, 9/11/2002; Washington Times, 10/8/2002] According to Clarke, Bush begins the meeting by saying, “I’m coming back to the White House as soon as the plane is fueled. No discussion.” But according to Condoleezza Rice, he begins with the words, “We’re at war.” Clarke leads a quick review of what has already occurred, and issues that need to be quickly addressed. Bush asks CIA Director Tenet who he thinks is responsible for the day’s attacks. Tenet later recalls, “I told him the same thing I had told the vice president several hours earlier: al-Qaeda. The whole operation looked, smelled, and tasted like bin Laden.” Tenet tells Bush that passenger manifests show that three known al-Qaeda operatives had been on Flight 77. According to Tenet, when he tells the president in particular about Nawaf Alhazmi and Khalid Almihdhar (two of the alleged Flight 77 hijackers), Bush gives Mike Morell, his CIA briefer, “one of those ‘I thought I was supposed to be the first to know’ looks.” (Other evidence indicates the third al-Qaeda operative whose name is on the passenger manifest would be Salem Alhazmi (see 9:53 p.m. September 11, 2001).) Tenet tells the meeting that al-Qaeda is “the only terrorist organization capable of such spectacular, well-coordinated attacks,” and that “Intelligence monitoring had overheard a number of known bin Laden operatives congratulating each other after the attacks. Information collected days earlier but only now being translated indicated that various known operatives around the world anticipated a big event. None specified the day, time, place or method of attack.” Richard Clarke later corroborates that Tenet had at this time told the president he was certain that al-Qaeda was to blame. Yet only six weeks later, in an October 24, 2001 interview, Rice will claim differently. She will say, “In the first video conference, the assumption that everybody kind of shared was that it was global terrorists.… I don’t believe anybody said this is likely al-Qaeda. I don’t think so.” Tenet also relays a warning the CIA has received from French intelligence, saying another group of terrorists is within US borders and is preparing a second wave of attacks. Defense Secretary Rumsfeld briefs on the status of US forces, and states that about 120 fighters are now above US cities.

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

Fighter pilots who have been escorting Air Force One as it transports President Bush across the US are not informed that the president’s plane is departing Offutt Air Force Base, Nebraska, and have to try and catch up with it after they hear it taking off. The pilots belong to the 147th Fighter Wing of the Texas Air National Guard. Four F-16s from the wing have been escorting Air Force One since before it landed at Barksdale Air Force Base, Louisiana (see (11:29 a.m.) September 11, 2001).
Pilots Told They Would Be Called When Air Force One Is Leaving - After Air Force One landed at Offutt Air Force Base (see 2:50 p.m. September 11, 2001), the F-16s landed there as well. The fighter pilots then met with Colonel Mark Tillman, the pilot of Air Force One. Tillman asked them about the capabilities of the F-16. He also took down their cell phone numbers and said he would call them when Air Force One would be leaving the base. However, he was unable to tell them where Air Force One would be going next, so the fighter pilots could not file a flight plan. The fighter pilots then headed off to get a snack and a drink.
Air Force One Takes Off, Pilots Not Informed - However, they are not informed when Air Force One, with Bush on board, takes off from Offutt (see (4:33 p.m.) September 11, 2001). One of the fighter pilots, Major Shane Brotherton, will later recall: “We were eating our snacks and heard jet noise. It was Air Force One and they’d never called us. We got to the jets and he’s taxiing fast and never stopped. Now we’re taxiing fast and we blast off.” By the time the fighters are airborne, Air Force One is 100 miles ahead of them. Some Iowa Air National Guard fighters from Sioux City are also now airborne to protect the president’s plane, but the 147th Fighter Wing jets continue to follow it. Brotherton will recall: “All across the country we were playing catch up, because [Air Force One] was moving. And we didn’t catch up until we were nearing Washington.” [Filson, 2003, pp. 87-88]

[Washington Post, 9/27/2001; Slate, 9/28/2001; Wall Street Journal, 3/22/2004 pdf file] The White House reportedly received an anonymous phone call at around 10:30 a.m. on September 11 in which the caller said Air Force One would be the next terrorist target and used code words indicating they had inside information about government procedures (see (10:30 a.m.) September 11, 2001). Vice President Dick Cheney promptly phoned President Bush on Air Force One and told him about the threat (see (10:32 a.m.) September 11, 2001). [New York Times, 9/13/2001; Woodward, 2002, pp. 18; 9/11 Commission, 7/24/2004, pp. 554]
Press Secretary Reveals Threat during News Briefing - White House press secretary Ari Fleischer reveals the existence of the threat on September 12, after conferring with Cheney and White House counselor Karen Hughes about whether the administration should respond to criticisms of Bush’s failure to return to Washington, DC, immediately after the previous day’s attacks. Hughes advises Fleischer to mention the threat during his press briefing on this day. [9/11 Commission, 7/24/2004, pp. 554; Fleischer, 2005, pp. 157] Fleischer therefore says in the briefing, “[W]e have specific and credible information that the White House and Air Force One were also intended targets of these attacks.” He says the threat against the president’s plane led to the decision to take Bush to Offutt Air Force Base in Nebraska (see 2:50 p.m. September 11, 2001) and was one of the reasons why Bush did not head back to Washington right away in response to the attacks. [White House, 9/12/2001]
Cheney Recalls 'Credible Threat' - On September 16, Cheney similarly tells NBC’s Meet the Press, “We received a threat to Air Force One,” and adds, “I think it was a credible threat, enough for the Secret Service to bring it to me.” [Meet the Press, 9/16/2001] And later in the month, White House adviser Karl Rove, who was with Bush on Air Force One on September 11, recalls that those on the president’s plane were informed of “a specific threat made to Air Force One,” which was a “declaration that Air Force One was a target.” [New Yorker, 9/25/2001]
Unnamed Officials Doubt whether Threat Was Made - Other officials, however, contradict these accounts. Near the end of September, CBS News reports that the phone call in which the threat was reportedly made “simply never happened.” It says that, according to unnamed sources, “White House staffers apparently misunderstood comments made by their security detail.” [Slate, 9/28/2001] And some unnamed Bush administration officials tell the Associated Press that “they now doubt whether there was actually a call made threatening Air Force One.” The officials say they “have been unsuccessful in trying to track down whether there was such a call, though officials still maintain they were told of a telephone threat [on] September 11 and kept Bush away from Washington for hours because of it.” [Associated Press, 9/26/2001] Fleischer will later recall that he learns, weeks after publicly revealing the existence of the supposed threat against Air Force One, “that the threat was unfounded.” [9/11 Commission, 7/24/2004, pp. 554] “I learned it was a mistake from the press,” he will say, “who had been tipped by someone who knew.” [Fleischer, 2005, pp. 158]
Threat Was 'Almost Surely Bogus' - At the start of November, when asked about the alleged call in which Air Force One was threatened, National Security Adviser Condoleezza Rice says: “I don’t know if it was a crank call or a real threat. I don’t think we’re going to ever know.” [White House, 11/1/2001] And at the end of 2001, Newsweek reports that the reported threat to Air Force One has been determined to be “almost surely bogus,” although it adds, “White House officials say they do not know where it came from.” [Newsweek, 12/30/2001] White House spokesman Dan Bartlett says in 2004 that “there hadn’t been any actual threat” against Air Force One on September 11. Word of a threat, he says, “resulted from confusion in the White House bunker, as multiple conversations went on simultaneously.” Around the same time, however, Cheney’s office says it still cannot rule out that a threat to Air Force One was made.

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.

[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).

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]
