Shortly Before 11:45 a.m. September 11, 2001: Fighter Jet Intercepts Suspicious Aircraft Flying toward Air Force One

Colonel Mark Tillman, the pilot of Air Force One, is informed that an unidentified aircraft is heading toward his plane, and one of the fighter jets that is escorting Air Force One then goes and intercepts this suspicious aircraft. [Aero-News Network, 7/19/2012; KFDI, 12/11/2012] Air Force One is flying toward Barksdale Air Force Base in Louisiana and has now been joined by two F-16 fighters belonging to the 147th Fighter Wing of the Texas Air National Guard (see (11:29 a.m.) September 11, 2001).

Pilot Says Aircraft Will Be Shot Down if It Is Hostile – The pilot of one of the fighters calls Tillman and tells him, “There’s a guy coming off New Orleans, looks like New Orleans, and he’s coming off and he’s climbing right at us, he’s coming right up at us.” He says he has instructed the pilot of the other fighter to head out to locate and identify the aircraft, and, he says, if the aircraft is “not a friendly, he’s gonna go ahead and splash him.” Tillman asks the pilot, “Who has got shootdown authority here?” and is told, “You have shootdown authority.” He then phones the president’s office, downstairs on Air Force One, and says to the person who answers, “Let the president know: the fighters on the wing say that I have shootdown authority.” Tillman then hears “a little chuckle in the background,” which, he will later say, is the “president and everybody laughing ‘cause Tillman thinks he has shootdown authority.”
Aircraft Is Just a Learjet Flown by a Civilian – The suspicious aircraft is intercepted by the fighter that went to locate and identify it. It turns out to be a Learjet piloted by a civilian, according to Tillman, which has just taken off from Lakefront Airport in New Orleans. “My angle coming in [toward Barksdale Air Force Base] was coming right over New Orleans and he’s taking off, coming right at me,” Tillman will say. [US Air Force, 2/29/2012 ; Aero-News Network, 7/19/2012; KFDI, 12/11/2012] If this is correct, it is unclear why the aircraft was permitted to take off, since the FAA ordered a nationwide ground stop at around 9:26 a.m., which was supposed to prevent any aircraft taking off across the US (see (9:26 a.m.) September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; 9/11 Commission, 7/24/2004, pp. 25] “It’s the only guy in the country that didn’t get the word we’re not flying today,” Tillman will comment. Finally, according to Tillman, the FAA’s Houston Center gets the Learjet back on the ground. [KFDI, 12/11/2012] Air Force One then heads on to Barksdale Air Force Base, where it will land at 11:45 a.m. (see 11:45 a.m. September 11, 2001). [CBS News, 9/11/2002]
