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.

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]

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]

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).

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). [Omaha World-Herald, 2/27/2002; GlobalSecurity (.org), 4/27/2005] Many aircraft and personnel at Barksdale, as well as other military bases, are involved in it (see 8:48 a.m. September 11, 2001). [Times-Picayune, 9/8/2002] Global Guardian will be formally terminated at 10:44 a.m., according to The Bombardier (see (10:44 a.m.) September 11, 2001), although other reports will say it is canceled earlier on, possibly after the second World Trade Center tower is hit at 9:03 a.m. [Omaha World-Herald, 2/27/2002; Omaha World-Herald, 9/8/2002; Bombardier, 9/8/2006 pdf file]

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

Air Force One at Barksdale Air Force Base.Air Force One at Barksdale Air Force Base. [Source: Win McNamee / Reuters]Air Force One, with President Bush on board, lands at Barksdale Air Force Base—the home of the B-52 bomber—near Shreveport, Louisiana. [New York Times, 9/16/2001; Daily Telegraph, 12/16/2001; BBC, 9/1/2002] The president’s plane was escorted by fighter jets from the 147th Fighter Wing of the Texas Air National Guard as it came in to land (see (11:29 a.m.) September 11, 2001). [Time, 9/14/2001; Filson, 2003, pp. 87; Bush, 2010, pp. 132] Two of those fighters now land at Barksdale with Air Force One while the other two remain airborne, flying a combat air patrol over Shreveport and Bossier City. Aircraft and personnel at Barksdale were participating in the major training exercise Global Guardian this morning, before the terrorist attacks began (see 8:48 a.m. September 11, 2001), and after touching down, Air Force One taxies past 40 fully loaded B-52s. [Times-Picayune, 9/8/2002; Bombardier, 9/8/2006 pdf file; Draper, 2007, pp. 141] Air Force personnel dressed in full combat gear and brandishing M-16s then set up a perimeter around the plane. [Time, 9/14/2001] Bush initially remains on board, gathering more intelligence. There is no mobile gangway on the tarmac and so he is unable to get off through his usual door in the top half of Air Force One. Instead, the flight crew opens a hatch near the belly of the plane and lowers a set of retractable stairs while Bush continues working the phones. The president finally gets off the plane just before noon and is then escorted away from it amid tight security (see (11:55 a.m.) September 11, 2001). [Sammon, 2002, pp. 111-112] The Daily Telegraph will later comment, “The official reason for landing at Barksdale was that Mr. Bush felt it necessary to make a further statement (see 12:36 p.m. September 11, 2001), but it isn’t unreasonable to assume that—as there was no agreement as to what the president’s movements should be—it was felt he might as well be on the ground as in the air.” [Daily Telegraph, 12/16/2001] Bush will remain at Barksdale Air Force Base for almost two hours before taking off again on Air Force One (see 1:37 p.m. September 11, 2001).
