Bill Clinton is re-inaugurated as president. An extensive set of security measures to prevent airplanes as weapons crashing into the inauguration is used. These measures, first used at the 1996 Atlanta Olympics and thus referred to as the “Atlanta Rules,” include the closing of nearby airspace, the use of intercept helicopters, the basing of armed fighters nearby, and more. This plan will later be used for the 1999 North Atlantic Treaty Organization’s 50th anniversary celebration in Washington, the 2000 Republican convention in Philadelphia, the 2000 Democratic convention in New York, and the George W. Bush inauguration in 2001. [Clarke, 2004, pp. 110-11; Wall Street Journal, 4/1/2004]
Plans for Permanent Air Defense Unit Rejected - At some point near the end of the Clinton administration, the Secret Service and Customs Service will agree to create a permanent air defense unit to protect Washington. However, these agencies are part of the Treasury Department, and the leadership there will refuse to fund the idea. White House counterterrorism “tsar” Richard Clarke will later recount: “Treasury nixed the air defense unit, and my attempts within the White House to overrule them came to naught. The idea of aircraft attacking in Washington seemed remote to many people and the risks of shooting down aircraft in a city were thought to be far too high.” The permanent unit will not be created until after 9/11.

General Richard B. Myers takes over as commander in chief of the North American Aerospace Defense Command (NORAD), commander in chief of the US Space Command, and commander of the Air Force Space Command. He replaces General Howell M. Estes III. [North American Aerospace Defense Command, 6/3/1998; Air Force News, 8/19/1998] Myers will serve in these positions until February 22, 2000, when he will be replaced by General Ralph E. Eberhart. [Air Force News, 2/22/2000] On 9/11, Myers will serve as the acting chairman of the Joint Chiefs of Staff. [Myers, 2009, pp. 10]

At some point during his tenure as commander in chief of NORAD (see August 14, 1998), General Richard Myers expresses concerns about the adequacy of the radar system over the US, which NORAD shares with the Federal Aviation Administration (FAA) in what is called the Joint Surveillance System. Myers will later tell the 9/11 Commission that NORAD is unable to “correlate” over 50 percent of the unknown radar tracks it picks up, either because it cannot launch an interceptor aircraft in time or because it cannot deal with the tracks appropriately. Some of them disappear from radar before NORAD can correlate them with the FAA. Myers makes Pentagon officials aware of the problem, telling them, “don’t think we’re providing 100 percent air sovereignty here… we’re looking outward, and a number of those tracks are never correlated.” He will recall that in connection with the internal radar issue, “I saw a letter I put out talking about a potential terrorist issue… that’s why you would want these radars up… it’s kind of a future issue.” According to Myers, there is talk about the future potential of a terrorist threat as a rationale for “trying to get people to address the FAA/[Air Force] radar funding issue in a more robust way.” Myers also finds NORAD’s command and control software inadequate. He will tell the 9/11 Commission that the “system was very old and was contracted to be replaced, but the contractor did not perform. The issue was how many tracks the system could handle at once; NORAD kept modifying the equipment to allow more inputs but it needed a new system.” However, Myers will also confirm to the 9/11 Commission that “from a technical radar standpoint, NORAD had pretty good coastal range, and that the activity on 9/11 was within the radar area that was accessible to NORAD.” [9/11 Commission, 2/17/2004 pdf file; 9/11 Commission, 6/9/2004]

The United Nations headquarters building in New York.The United Nations headquarters building in New York. [Source: Mark Garten / United Nations]The North American Aerospace Defense Command (NORAD) practices a scenario in which five terrorists take over a transcontinental aircraft with the intention of crashing it into the United Nations headquarters building in New York. The simulation takes place during a command post exercise conducted by the Continental United States NORAD Region, called Falcon Indian. NORAD’s three air defense sectors in the continental US, including the Northeast Air Defense Sector based in Rome, New York, take part in this exercise. General Richard Myers, currently the commander in chief of NORAD, will reveal the details of the scenario during an August 2004 hearing of the Senate Armed Services Committee. According to Myers, the scenario is based around a China Air aircraft flying from Los Angeles to JFK International Airport in New York, which is “hijacked east of Colorado Springs by five terrorists.” If the plane is not intercepted by the US military, the terrorists intend “to crash into [the] United Nations building.” [North American Aerospace Defense Command, 8/25/1989; US Congress. Senate. Committee on Armed Services, 8/17/2004; Arkin, 2005, pp. 362] The UN headquarters building is a 39-story high-rise, located a few miles from the World Trade Center. [New York Daily News, 12/2/1999; Evening Standard, 9/11/2002] In response to the simulated crisis, exercise participants have to follow hijack checklists, exercise command and control, coordinate with external agencies, and carry out a handover of responsibilities between NORAD sectors. [US Congress. Senate. Committee on Armed Services, 8/17/2004] Like in this scenario, the teams of hijackers that take over three of the four aircraft targeted in the 9/11 attacks will comprise of five terrorists. And all four of the aircraft targeted on 9/11 will be making transcontinental flights, like the plane hijacked in this scenario, although they will be flying from the east coast to the west rather than from the west to the east. [New York Times, 9/12/2001; CNN, 9/20/2001; 9/11 Commission, 7/24/2004, pp. 4, 11] A subsequent Falcon Indian exercise in June 2000 will include scenarios in which hijackers plan to crash aircraft into the White House and the Statue of Liberty (see June 5, 2000).

The Statue of Liberty, with the World Trade Center standing behind it.The Statue of Liberty, with the World Trade Center standing behind it. [Source: Port Authority of New York and New Jersey]The North American Aerospace Defense Command (NORAD) practices two scenarios in which aircraft are hijacked, and in one scenario the hijackers plan to crash the plane into the Statue of Liberty in New York Harbor, while in the other the hijackers plan to crash into the White House in Washington, DC. The scenarios are included in a command post exercise conducted by the Continental United States NORAD Region called Falcon Indian. NORAD’s three air defense sectors in the continental United States, including the Northeast Air Defense Sector based in Rome, New York, are participating in this exercise. [North American Aerospace Defense Command, 8/25/1989; US Congress. Senate. Committee on Armed Services, 8/17/2004; Arkin, 2005, pp. 362]
Hijackers Take Over Learjet, Plan to Crash into White House - The two hijacking scenarios will be described by General Richard Myers, currently the vice chairman of the Joint Chiefs of Staff, during a hearing of the Senate Armed Services Committee in August 2004. According to Myers, one of the scenarios involves a Learjet being hijacked and maintaining a “tight formation with [a] Canadair airliner, loaded with explosives.” (From Myers’s description it is unclear whether the Learjet or the Canadair airliner is the plane carrying explosives.) According to Myers, the “Learjet planned to crash into the White House.” In response to the simulated crisis, exercise participants have to follow hijack checklists, exercise command and control, and coordinate with external agencies.
Communist Group Plans to Crash Plane into Statue of Liberty - The other scenario is based around a “Communist Party faction” that hijacks an aircraft “bound from [the] western to [the] eastern United States,” according to Myers. There are “[h]igh explosives on board” the aircraft and the fictitious hijackers intend “to crash into the Statue of Liberty.” During the simulation, the FAA requests assistance from the military. Exercise participants have to again follow hijack checklists, exercise command and control, and coordinate with external agencies, as well as carrying out a handover of responsibilities between NORAD sectors. [US Congress. Senate. Committee on Armed Services, 8/17/2004] Even though these two NORAD exercise scenarios involve hijackers attempting to use planes as weapons, the 9/11 Commission will claim in its final report, “The threat of terrorists hijacking commercial airliners within the United States—and using them as guided missiles—was not recognized by NORAD before 9/11.” [9/11 Commission, 7/24/2004, pp. 17] A previous Falcon Indian exercise in November 1999 included a scenario of hijackers planning to crash an aircraft into the United Nations headquarters building in New York (see November 6, 1999).

A FedEx MD-11 aircraft.A FedEx MD-11 aircraft. [Source: Alan Radecki]The North American Aerospace Defense Command (NORAD) practices scenarios based around suicidal pilots planning to deliberately crash stolen aircraft into the United Nations headquarters—a skyscraper in New York. The two scenarios are practiced on October 16 and October 23 as part of NORAD’s annual command post exercise called Vigilant Guardian. All of NORAD, including its Northeast Air Defense Sector based in Rome, New York, participates in this exercise. [US Congress. Senate. Committee on Armed Services, 8/17/2004; Arkin, 2005, pp. 545; GlobalSecurity (.org), 4/27/2005]
Simulation Involves Planned Suicide Plane Attack - General Richard Myers, currently the vice chairman of the Joint Chiefs of Staff, will later describe the scenario practiced on October 16: “Due to recent arrests involving illegal drug trafficking in Maine, an individual steals a Federal Express plane and plans a suicide attack into the United Nations building in New York City.” In response to the simulated crisis, exercise participants follow hijack checklists, exercise command and control, and coordinate with external agencies.
Simulation Involves WMD Directed at the UN - The October 23 scenario, according to Myers, is based around “[w]eapons of mass destruction directed at the United Nations. An individual steals a Federal Express aircraft and plans a suicide attack on the United Nations building in New York City.” In response, exercise participants practice command and control, and coordinate with external agencies, and fighter jets conduct an interception of the stolen aircraft. [US Congress. Senate. Committee on Armed Services, 8/17/2004] Federal Express currently flies mostly the DC-10 and the MD-11, which are both large jet planes, so presumably one of these kinds of aircraft is considered in the exercise scenarios. [Washington Post, 1/17/2001] The UN headquarters building—the target in the scenarios—is a 39-story high-rise, located just a few miles from the World Trade Center. [New York Daily News, 12/2/1999; Evening Standard, 9/11/2002]
Scenarios Revealed in 2004 - The details of these two scenarios will come to light in August 2004 during a hearing of the Senate Armed Services Committee. They will be revealed by Myers, at that time the chairman of the Joint Chiefs of Staff, after Senator Mark Dayton (D-MN) asks him, “Did NORAD conduct exercises or develop scenarios, prior to September 11, 2001, to test a military reaction to an aircraft hijacking which appeared destined to result in a suicide crash into a high-value target?” [US Congress. Senate. Committee on Armed Services, 8/17/2004] NORAD will state in 2004 that, until 9/11, it conducts four major exercises each year. Most of these include a hijack scenario, but not all of them involve planes being used as weapons. [USA Today, 4/18/2004; CNN, 4/19/2004] NORAD’s next Vigilant Guardian exercise, in 2001, will actually be several days underway on 9/11 (see (6:30 a.m.) September 11, 2001). It will include a number of scenarios based around plane hijackings, with the fictitious hijackers targeting New York in at least one of those scenarios (see September 6, 2001, September 9, 2001, September 10, 2001, and (9:40 a.m.) September 11, 2001).

Acting on previous warnings that al-Qaeda would attempt to kill President Bush and other leaders, Italian authorities surround the summit with anti-aircraft guns. They keep fighter jets in the air and close off local airspace to all planes. [Los Angeles Times, 9/27/2001] The warnings are taken so seriously that Bush stays overnight on an aircraft carrier offshore, and other world leaders stay on a luxury ship. [CNN, 7/18/2001] No attack occurs. US officials state that the warnings were “unsubstantiated,” but after 9/11, they will claim success in preventing an attack. [Los Angeles Times, 9/27/2001] According to author Philip Shenon, National Security Adviser Condoleezza Rice is involved in discussions about the precautions, and this is the only time she focuses on al-Qaeda threats in the summer of 2001. Shenon will add: “There is no record to show that Rice made any special effort to discuss terrorist threats with Bush. The record suggested, instead, that it was not a matter of special interest to either of them that summer.” [Shenon, 2008, pp. 154]

The North American Aerospace Defense Command (NORAD) practices for dealing with the simulated hijackings of two commercial aircraft by terrorists, as part of its annual training exercise called Vigilant Guardian. Whether the simulated hijackings take place simultaneously or at different times of the day is unclear. [9/11 Commission, 2004; Spencer, 2008, pp. 3]
Terrorists Threaten to 'Rain Terror from the Skies' - One of the two exercise scenarios involves the hijacking of a Boeing 747 bound from Tokyo, Japan, to Anchorage, Alaska. According to a document later produced by the 9/11 Commission, the scenario involves the “[t]hreat of harm to [the plane’s] passengers and possibly [a] large population within [the] US or Canada.” It includes what is apparently a fictitious Asian terrorist group called “Mum Hykro,” which is threatening to “rain terror from the skies onto a major US city unless the US declares withdrawal from Asian conflict.” During the hijacking scenario, some of the plane’s passengers are killed. The plane’s course is changed to take it to Vancouver, Canada, and then to San Francisco, California. In response to the hijacking, the chairman of the Joint Chiefs of Staff and FAA headquarters direct military assistance, in the form of “covert shadowing” of the hijacked aircraft. NORAD has to liaise with the appropriate air traffic control centers. Its Alaskan region (ANR) and its Canadian region (CANR) participate in the scenario.
Group Threatens to Blow up Plane - In the other hijacking scenario, 10 members of another fictitious terrorist group, “Lin Po,” seize control of a Boeing 747 bound from Seoul, South Korea, to Anchorage. The hijackers have weapons on board that were smuggled onto the plane in small tote bags by ground crew members prior to takeoff. Gas containers were also smuggled onto the aircraft by baggage handlers before takeoff. Arming devices are attached to these containers, which can be remotely detonated. The terrorist group issues demands and threatens to blow up the plane if these are not met. The CIA and NSA caution that the group has the means and motivation to carry out a chemical and biological attack. The group kills two of the plane’s passengers and threatens to use the gas it has on board in some manner. In response to the simulated hijacking, NORAD directs fighter jets to get in a position to shoot down the hijacked airliner, and orders ANR to intercept and shadow it. In the scenario, the 747 eventually lands in Seattle, Washington. [9/11 Commission, 2004]
Most NORAD Exercises Include Hijack Scenario - Vigilant Guardian is one of four major exercises that NORAD conducts each year. Most of these exercises include a hijack scenario. [USA Today, 4/18/2004] Ken Merchant, NORAD’s joint exercise design manager, will tell the 9/11 Commission in 2003 that he cannot “remember a time in the last 33 years when NORAD has not run a hijack exercise.” [9/11 Commission, 11/14/2003 pdf file] This year’s Vigilant Guardian will include additional aircraft hijacking scenarios on September 9 and September 10 (see September 9, 2001 and September 10, 2001), and a further simulated plane hijacking is scheduled for the morning of September 11 (see (9:40 a.m.) September 11, 2001).

Personnel at NORAD’s Northeast Air Defense Sector (NEADS) practice their responses to a simulated plane hijacking in which terrorists plan to blow up a hijacked airliner over New York City. The scenario is part of the annual NORAD training exercise Vigilant Guardian. [9/11 Commission, 2004; Spencer, 2008, pp. 3] In the scenario, the fictitious hijackers take over a McDonnell Douglas DC-10 aircraft bound from London, Britain, to JFK International Airport in New York. According to a document later produced by the 9/11 Commission, the terrorist hijackers have explosives on the plane and “plan to detonate them over NYC.” As the scenario plays out, a “Blue Force” is able to divert the hijacked aircraft. When the terrorists then realize they are not near New York, they “detonate [the] explosives over land near the divert location.” There are no survivors. [9/11 Commission, 2004] NEADS is based in Rome, New York, and will play a key role in coordinating the US military’s response to the 9/11 attacks two days later. On the morning of September 11, its personnel will be scheduled to practice another scenario based around an aircraft hijacking, presumably as part of the same Vigilant Guardian exercise (see (9:40 a.m.) September 11, 2001).

Personnel at NORAD’s Southeast Air Defense Sector (SEADS) at Tyndall Air Force Base, Florida, practice for the scenario of an aircraft being hijacked by Cuban asylum seekers. The scenario is part of the annual NORAD training exercise, Vigilant Guardian. [9/11 Commission, 2004; Spencer, 2008, pp. 3] In the scenario, the fictitious hijackers take over an Ilyushin IL-62 jet airliner that took off from Havana, Cuba. The hijackers, who are “demanding political asylum, demand to be taken to” New York City, according to a document later produced by the 9/11 Commission. As the scenario plays out, the FAA requests support from NORAD. The FAA directs the plane toward Jacksonville, Florida, but the hijackers then demand to be taken to Atlanta, Georgia. Finally, the hijacked plane lands safely at Dobbins Air Force Base in Georgia. [9/11 Commission, 2004] The following morning, September 11, personnel at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York, are scheduled to practice what is apparently a similar plane hijacking scenario, presumably as part of the same Vigilant Guardian exercise (see (9:40 a.m.) September 11, 2001). According to Vanity Fair, that scenario will involve “politically motivated perpetrators” seeking asylum “on a Cuba-like island.” [Vanity Fair, 8/1/2006]

NORAD is conducting a week-long, large-scale exercise called Vigilant Guardian. [Newhouse News Service, 1/25/2002] Deskins is regional mission crew chief for the Vigilant Guardian exercise. [ABC News, 9/11/2002]
Exercise Includes Simulated Attack on the US - Vigilant Guardian is described as “an exercise that would pose an imaginary crisis to North American Air Defense outposts nationwide”; as a “simulated air war”; and as “an air defense exercise simulating an attack on the United States.” According to the 9/11 Commission, it “postulated a bomber attack from the former Soviet Union.” [Newhouse News Service, 1/25/2002; Filson, 2003, pp. 55 and 122; 9/11 Commission, 7/24/2004, pp. 458] Vigilant Guardian is described as being held annually, and is one of NORAD’s four major annual exercises. [Filson, 2003, pp. 41; Arkin, 2005, pp. 545; GlobalSecurity (.org), 4/27/2005] However, one report says it takes place semi-annually. [Aviation Week and Space Technology, 6/3/2002] Accounts by participants vary on whether 9/11 is the second, third, or fourth day of the exercise. [Code One Magazine, 1/2002; Newhouse News Service, 1/25/2002; Ottawa Citizen, 9/11/2002] Vigilant Guardian is a command post exercise (CPX), and in at least some previous years was conducted in conjunction with Stratcom’s Global Guardian exercise and a US Space Command exercise called Apollo Guardian. [US Congress, n.d.; Arkin, 2005, pp. 545; GlobalSecurity (.org), 4/27/2005] All of NORAD is participating in Vigilant Guardian on 9/11. [Aviation Week and Space Technology, 6/3/2002]
Exercise Includes Simulated Hijacking - Vanity Fair reports that the “day’s exercise” (presumably Vigilant Guardian) is “designed to run a range of scenarios, including a ‘traditional’ simulated hijack in which politically motivated perpetrators commandeer an aircraft, land on a Cuba-like island, and seek asylum.” [Vanity Fair, 8/1/2006] However, at NEADS, most of the dozen or so staff on the operations floor have no idea what the exercise is going to entail and are ready for anything. [Utica Observer-Dispatch, 8/5/2004]
NORAD Fully Staffed and Alert - NORAD is currently running a real-world operation named Operation Northern Vigilance (see September 9, 2001). It may also be conducting a field training exercise calling Amalgam Warrior on this morning (see 9:28 a.m. September 11, 2001). NORAD is thus fully staffed and alert, and senior officers are manning stations throughout the US. The entire chain of command will be in place and ready when the first hijacking is reported. An article later says, “In retrospect, the exercise would prove to be a serendipitous enabler of a rapid military response to terrorist attacks on September 11.” [Aviation Week and Space Technology, 6/3/2002; Bergen Record, 12/5/2003] Colonel Robert Marr, in charge of NEADS, will say: “We had the fighters with a little more gas on board. A few more weapons on board.” [ABC News, 9/11/2002] However, Deskins and other NORAD officials later are initially confused about whether the 9/11 attacks are real or part of the exercise (see (8:38 a.m.-8:43 a.m.) September 11, 2001).

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

Doug Lute.Doug Lute. [Source: Joint Chiefs of Staff]General Henry Shelton, the chairman of the Joint Chiefs of Staff, learns of the terrorist attacks in New York and at the Pentagon while flying to Europe, but his plane is then initially denied permission to return to the US. Shelton’s plane took off from Andrews Air Force Base, near Washington, DC, at 7:15 a.m. to transport the chairman to Hungary for a NATO conference (see 7:15 a.m. September 11, 2001). [Federal Aviation Administration, 3/21/2002, pp. G-1 pdf file; Giesemann, 2008, pp. 20, 22-23; Shelton, Levinson, and McConnell, 2010, pp. 430-432]
Shelton Learns of First Crash - About an hour and a half into the flight, while the plane is over the Atlantic Ocean, a member of the flight crew approaches Colonel Doug Lute, Shelton’s executive assistant, and tells him a small aircraft has crashed into one of the World Trade Center towers. Lute says, “That doesn’t sound good.” He goes to the chairman’s cabin at the rear of the aircraft and tells Shelton, “Sir, just to advise you, the pilot has received word that a civilian aircraft has just struck the World Trade Center.” Shelton is reminded of a speech he recently gave, in which he warned of the possibility of a terrorist attack on US soil (see (Shortly Before September 11, 2001)), and says to his wife, Carolyn, who is with him in the cabin, “I sure hope that is not a terrorist attack.” He will later recall, “This had the potential to play out exactly as I had warned.”
Shelton Learns of Second Crash - About 10 minutes after Lute returns to his seat, the member of the flight crew comes out again and reports that a second plane has crashed into the WTC. Lieutenant Commander Suzanne Giesemann, one of Shelton’s aides, says to Lute, “That can’t be an accident.” Lute goes again to Shelton’s cabin and tells the chairman, “Sir, it’s a second plane and it’s hit the other tower of the World Trade Center.” Shelton exclaims: “Doug, that’s no coincidence. Have them turn us around, we’re going back. Then I want General Myers on the line.” (General Richard Myers is the vice chairman of the Joint Chiefs of Staff.) After Lute returns to his seat, he and Giesemann put on headsets and make calls to the Pentagon. Giesemann talks to Kris Cicio, Shelton’s personal assistant, who tells her that the WTC towers were hit not by small planes, but by jetliners full of innocent passengers. Giesemann then loses her connection with Cicio, and so listens instead to BBC news reports through her headset and passes on what she learns to the other members of Shelton’s staff on the flight. Lute talks with someone in the National Military Command Center (NMCC) at the Pentagon. After the call, he heads to Shelton’s cabin. [Giesemann, 2008, pp. 22-23; Shelton, Levinson, and McConnell, 2010, pp. 431]
Controllers Deny Request to Enter US Airspace - Having learned of the attack on the Pentagon (which takes place at 9:37 a.m.), Lute tells Shelton that there has been “some type of big explosion at the Pentagon.” He also tells the chairman that air traffic controllers have refused their request to fly into Washington. Lute says: “[W]e’ve been denied permission to return. All US airspace has been shut down” (see (9:45 a.m.) September 11, 2001). But Shelton retorts: “Doug, tell the pilot we’ll ask for forgiveness instead of permission, so have him turn us around. We’re going home.” Shelton will later recall, “I knew there was no way they were going to shoot down a 707 with UNITED STATES AIR FORCE emblazoned along the side.” [Federal Aviation Administration, 3/21/2002, pp. G-1 pdf file; Shelton, Levinson, and McConnell, 2010, pp. 432]
Shelton's Plane Supposedly Cleared to Fly into Washington - After Lute returns from Shelton’s cabin, he nods to Giesemann and says, “We’re going back.” Giesemann will recall that she then heads into the cockpit and orders the pilot, “Major, take us back to Andrews.” The pilot replies, “Yes, ma’am.” [Giesemann, 2008, pp. 23] According to an FAA report, “minutes” after the initial denial of permission to return to the US, Shelton’s plane is granted clearance. [Federal Aviation Administration, 3/21/2002, pp. G-1 pdf file] The pilot turns the plane around and heads back toward Washington, according to Shelton. [Shelton, Levinson, and McConnell, 2010, pp. 432] But according to Captain Rob Pedersen, the flight navigator on Shelton’s plane, it is several hours before the plane is cleared to enter the US airspace (see (After 9:45 a.m.) September 11, 2001). [Air Force Magazine, 9/2011 pdf file] The plane will consequently only land at Andrews Air Force Base at 4:40 p.m. (see 4:40 p.m. September 11, 2001) and Shelton will only arrive at the NMCC an hour after that (see 5:40 p.m. September 11, 2001).

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).

Alan Scott.Alan Scott. [Source: United States Air Force]NORAD’s Northeast Air Defense Sector (NEADS) processes and transmits an order to Langley Air Force Base in Virginia, to scramble three of its F-16 fighter jets. [North American Aerospace Defense Command, 9/18/2001; Christian Science Monitor, 4/16/2002; 9/11 Commission, 8/26/2004, pp. 16] NEADS mission crew commander Major Kevin Nasypany instructed his personnel to issue this order one minute earlier (see 9:23 a.m. September 11, 2001). Although he’d originally wanted the Langley jets sent to the Washington area, he will soon adjust this heading to send them to the Baltimore area. [9/11 Commission, 7/24/2004, pp. 27]
NEADS Orders Jets North - A NEADS officer calls Langley Air Force Base and instructs: “Langley command post, this is Huntress with an active air defense scramble for Quit 2-5 and Quit 2-6.… Scramble immediately.… Scramble on a heading of 010, flight level 290.” This means the jets are to head in a direction just east of north, at an altitude of 29,000 feet. [9/11 Commission, 1/9/2004; 9/11 Commission, 8/26/2004, pp. 96; Spencer, 2008, pp. 142] At Langley Air Force Base, a Klaxon horn will sound, notifying the pilots of the scramble order (see 9:24 a.m. September 11, 2001), and they will be airborne by 9:30 (see (9:25 a.m.-9:30 a.m.) September 11, 2001). [Filson, 2003, pp. 63; 9/11 Commission, 8/26/2004, pp. 16; Spencer, 2008, pp. 141]
Fighters Launched in Response to Flight 77? - In later testimony, military officials will give contradictory explanations for why the Langley F-16s are scrambled. An early NORAD timeline will indicate the fighters are launched in response to NORAD being notified at 9:24 that Flight 77 has been hijacked (see (9:24 a.m.) September 11, 2001). [North American Aerospace Defense Command, 9/18/2001] Colonel Alan Scott, the former vice commander of the Continental US NORAD Region (CONR), will suggest the same, telling the 9/11 Commission: “At 9:24 the FAA reports a possible hijack of [Flight] 77.… And at that moment as well is when the Langley F-16s were scrambled out of Langley.” [9/11 Commission, 5/23/2003; 1st Air Force, 8/8/2006] And a timeline provided by senior Defense Department officials to CNN will state, “NORAD orders jets scrambled from Langley” in order to “head to intercept” Flight 77. [CNN, 9/17/2001]
In Response to Flight 93? - However, Major General Larry Arnold, the CONR commander, will give a different explanation. He will tell the 9/11 Commission, “we launched the aircraft out of Langley to put them over top of Washington, DC, not in response to American Airline 77, but really to put them in position in case United 93 were to head that way.” [9/11 Commission, 5/23/2003]
In Response to Incorrect Report about Flight 11? - In 2004, the 9/11 Commission will dispute both these previous explanations, and conclude that the Langley jets are scrambled in response to an incorrect report that Flight 11 is still airborne and heading toward Washington, DC (see 9:21 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 26-27; 9/11 Commission, 8/26/2004, pp. 15] Tape recordings of the NEADS operations floor will corroborate this account. [Vanity Fair, 8/1/2006] According to the 9/11 Commission, its conclusion is also confirmed by “taped conversations at FAA centers; contemporaneous logs compiled at NEADS, Continental Region headquarters, and NORAD; and other records.” [9/11 Commission, 7/24/2004, pp. 34] Major Nasypany will tell the Commission that the reason the Langley jets are directed toward the Baltimore area is to position them between the reportedly southbound Flight 11 and Washington, as a “barrier cap.” [9/11 Commission, 7/24/2004, pp. 27 and 461] John Farmer, senior counsel to the 9/11 Commission, will later suggest that NORAD deliberately misled Congress and the Commission by hiding the fact that the Langley scramble takes place in response to the erroneous report that Flight 11 is still airborne. He will write that the mistaken report “appears in more logs, and on more tapes, than any other single event that morning.… It was the reason for the Langley scramble; it had triggered the Air Threat Conference Call. Yet it had never been disclosed; it was, instead, talked around.” [Farmer, 2009, pp. 266-267]
Conflicting Times - Early news reports will put the time of the scramble order slightly later than the 9/11 Commission places it, between 9:25 and “about 9:27.” [Washington Post, 9/12/2001; CNN, 9/17/2001; CNN, 9/19/2001] But a NORAD timeline released a week after the attacks will give the same time as the Commission does, of 9:24.

Hijackers Hani Hanjour, Khalid Almihdhar, Majed Moqed, Nawaf Alhazmi, and Salem Alhazmi presumably are killed instantly. (Typically, they are not included in the death counts.) [CNN, 9/17/2001; North American Aerospace Defense Command, 9/18/2001; Guardian, 10/17/2001; Washington Post, 11/21/2001; USA Today, 8/13/2002; Associated Press, 8/21/2002; MSNBC, 9/3/2002; ABC News, 9/11/2002; CBS, 9/11/2002] Flight 77 hits the first floor of the Pentagon’s west wall. The impact and the resulting explosion heavily damage the building’s three outer rings. The path of destruction cuts through Army accounting offices on the outer E Ring, the Navy Command Center on the D Ring, and the Defense Intelligence Agency’s comptroller’s office on the C Ring. [Vogel, 2007, pp. 431 and 449] Flight 77 strikes the only side of the Pentagon that had recently been renovated—it was “within days of being totally [renovated].” [US Department of Defense, 9/15/2001] “It was the only area of the Pentagon with a sprinkler system, and it had been reconstructed with a web of steel columns and bars to withstand bomb blasts. The area struck by the plane also had blast-resistant windows—two inches thick and 2,500 pounds each—that stayed intact during the crash and fire. While perhaps, 4,500 people normally would have been working in the hardest-hit areas, because of the renovation work only about 800 were there.” More than 25,000 people work at the Pentagon. [Los Angeles Times, 9/16/2001] Furthermore, the plane hits an area that has no basement. As journalist Steve Vogel later points out, “If there had been one under the first floor, its occupants could easily have been trapped by fire and killed when the upper floors collapsed.” [Vogel, 2007, pp. 450]

As part of a NORAD training exercise, a simulated plane hijacking was scheduled to occur around this time. It was to have been based around politically motivated perpetrators taking command of an aircraft, landing it on a Cuba-like island, and seeking asylum there. The hijacking was one of several simulated scenarios prepared for the day. Details of the other scenarios are unknown. Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS) who’d helped designed the exercise, initially thought the reports of Flight 11 being hijacked were because “Somebody started the exercise early.” [Vanity Fair, 8/1/2006] The exercise was canceled after the second plane hit the World Trade Center (see (Shortly After 9:03 a.m.) September 11, 2001).

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

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]

CBS News announces that “contrary to early reports, US Air Force jets did get into the air on Tuesday while the attacks were under way.” According to this new account, the first fighters got airborne toward New York City at 8:52 a.m. [CBS News, 9/14/2001] The day before this announcement, acting Chairman of the Joint Chiefs of Staff Richard Myers in Congressional testimony stated that the first fighters got airborne only after the Pentagon was hit at 9:37 a.m. (see September 13, 2001). [US Congress, 9/13/2001] NORAD spokesman Marine Corps Major Mike Snyder also claimed no fighters launched anywhere until after the Pentagon was hit. [Boston Globe, 9/15/2001] Four days later, the official NORAD timeline is changed to include this new account. [North American Aerospace Defense Command, 9/18/2001] New York City Mayor Rudolph Giuliani later testifies before the 9/11 Commission that he found out from the White House at about 9:58 a.m. that the first fighters were not launched toward New York City until twelve minutes earlier—9:46 a.m. [9/11 Commission, 5/19/2004] This would correspond to Myers’ and Snyder’s accounts that no fighters are scrambled until after the Pentagon is hit. But the 9/11 Commission later agrees with this CBS report and by their account the first fighters launch around 8:52. [9/11 Commission, 6/17/2004]

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

During the 9/11 Commission’s twelfth public hearing, Commissioner Jamie Gorelick is sharply critical of NORAD’s failure to protect the US on 9/11. NORAD failed because it “defined out of the job,” she says. “[W]here was our military when it should have been defending us?” she asks General Richard Myers, who was the acting Joint Chiefs of Staff chairman on 9/11. “And the response… is that NORAD was not postured to defend us domestically unless someone was coming at us from abroad.… That’s why I come back to this word posture, we were postured against an external threat.” But, says Gorelick, the military’s own directives clearly state that NORAD has an “air sovereignty” mission that is not limited to watching the borders. “[T]he foundation documents for NORAD, they do not say defend us only against a threat coming in from across the ocean, or across our borders. It has two missions, and one of them is control of the airspace above the domestic United States, and aerospace control is defined as providing surveillance and control of the airspace of Canada and the United States. To me that air sovereignty concept means that you have a role which, if you were postured only externally you defined out of the job.”
Posse Comitatus - Gorelick also dismisses the Posse Comitatus Act of 1876, which prohibits the military from acting in a law enforcement capacity, as one of the reasons for the military’s failure. When Myers invokes the act, she quickly interrupts him. Myers says, “What we try to do is follow the law, and the law is pretty clear on Posse Comitatus and that is whether or not the military should be involved in domestic law enforcement.” Gorelick replies: “Let me just interrupt, when I was general counsel of the Defense Department, I repeatedly advised, and I believe others have advised that the Posse Comitatus says, you can’t arrest people. It doesn’t mean that the military has no authority, obligation, or ability to defend the United Sates from attacks that happen to happen in the domestic United States.”
Unanswered Questions - Gorelick then pointedly asks Myers, a former NORAD commander, how the military came to neglect its air sovereignty mission: “[B]y what process was it decided to only posture us against a foreign threat?… [I]s it your job, and if not whose job is it, to make current assessments of a threat, and decide whether you are positioned correctly to carry out a mission, which at least on paper NORAD had?” She adds that on several occasions, such as the 1996 Olympics (see January 20, 1997) and the G8 summit in Genoa (see July 20-22, 2001), the government had prepared for air attacks. While Myers offers a general assurance that the US military is now better prepared for “non-traditional” attacks, he does not provide specific answers to Gorelick’s questions.
