Narrative:
A Learjet 35, N47BA, operated by Sunjet Aviation, crashed near Aberdeen, SD. The airplane departed Orlando, FL (MCO) for Dallas, TX (DAL) about 09:20 EDT. Radio contact with the flight was lost north of Gainesville, FL, after air traffic control (ATC) cleared the airplane to FL390. The airplane was intercepted by several U.S. Air Force (USAF) and Air National Guard (ANG) aircraft as it proceeded northwestbound. The military pilots in a position to observe the accident airplane at close range stated (in interviews or via radio transmissions) that the forward windshields of the Learjet seemed to be frosted or covered with condensation. The military pilots could not see into the cabin. They did not observe any structural anomaly or other unusual condition. The military pilots observed the airplane depart controlled flight and spiral to the ground, impacting an open field. All occupants on board the airplane (the captain, first officer, and four passengers) were killed, and the airplane was destroyed. Among the passengers was professional golfer Payne Stewart.

PROBABLE CAUSE: "Incapacitation of the flight crewmembers as a result of their failure to receive supplemental oxygen following a loss of cabin pressurization, for undetermined reasons. "
