Eglin Air Force Base

A runaway Learjet crashes near Mina, South Dakota, after flying on autopilot for several hours. On board is champion golfer Payne Stewart, along with five others. It is believed the accident is due to a loss of cabin pressure at high altitude, which would have caused all on board to go unconscious from lack of oxygen. [ABC News, 10/25/1999; Washington Post, 10/26/1999; National Transportation Safety Board, 11/28/2000] After air traffic controllers lost contact with the plane, it was tracked by the Federal Aviation Administration (FAA), assisted by several Air Force and Air National Guard fighters and an AWACS radar control plane, up until when it crashed. It was also tracked on radar screens inside the National Military Command Center in the Pentagon. [CNN, 10/26/1999] The Learjet had departed Orlando, Florida at 9:19 a.m., bound for Texas. The FAA says controllers lost contact with it at 9:44 a.m. [Washington Post, 10/26/1999] , but according to a later report by the National Transportation Safety Board (NTSB) the plane first failed to respond to air traffic control at 9:33 a.m., after which the controller repeatedly tried to make contact for the next 4 1/2 minutes, without success. [National Transportation Safety Board, 11/28/2000] NORAD’s Southeast Air Defense Sector was notified of the emergency at 9:55 a.m. [9/11 Commission, 7/24/2004, pp. 459] At 10:08 a.m., two F-16 fighters from Tyndall Air Force Base, Florida that were on a routine training mission had been asked by the FAA to intercept the Learjet, but never reached it. At about 10:52 a.m., a fighter from Eglin Air Force Base, Florida, was directed to within 9 miles of it, and at around 11:00 a.m. began a visual inspection of the plane. It accompanied the Learjet from 11:09 to 11:44 a.m. At 11:59 a.m., according to early accounts, four Air National Guard fighters and a refueling tanker from Tulsa, Oklahoma were told to chase the Learjet, but got no closer than 100 miles from it. However, the NTSB later claims that two Tulsa fighters were with it between 12:25 and 12:39 p.m., and were able to visually inspect it. At 12:54 p.m., two Air National Guard fighters from Fargo, North Dakota intercepted the Learjet. Soon after 1:14 p.m., it crashed in swampland, after spiraling to the ground. [Washington Post, 10/26/1999; Associated Press, 10/27/1999; National Transportation Safety Board, 11/28/2000] During its flight, the FAA had routed air traffic around the Learjet, and made sure no other planes flew beneath it, due to the danger of it crashing. [Associated Press, 10/26/1999] There is some discussion as to what could have been done had the plane been on a collision course with a populated area, with CNN reporting, “[O]nly the president has the authority to order a civilian aircraft shot down.” Pentagon spokesman Ken Bacon says the military has no written instructions for shooting down manned civilian planes. According to a 1997 military instruction, the shooting down of unmanned objects such as missiles requires prior approval from the secretary of defense. [US Department of Defense, 7/31/1997 ; CNN, 10/26/1999] A Pentagon spokesman says the fighters that monitored the Learjet had no missiles, but two other fighters on “strip alert” at Fargo had been armed but didn’t take off. [CNN, 10/26/1999] The 9/11 Commission will later compare NORAD’s response to this incident with its response to Flight 11 on 9/11, and claim: “There is no significant difference in NORAD’s reaction to the two incidents.” [9/11 Commission, 7/24/2004, pp. 459]
