8:48 a.m. September 11, 2001: Barksdale Air Force Base, Louisiana, Is Participating in an Exercise Based around a Simulated Nuclear Attack

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.

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.

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]
