Early in the flight, the aircraft, which was climbing to its assigned altitude on autopilot, lost cabin pressure, and all six on board were incapacitated by hypoxia, a lack of oxygen in the brain and body. On Tuesday, investigators reported that the recorder includes "sounds consistent with various alarms," including a low-pressure alarm. Retrieved from http://edition.cnn.com/US/9911/23/stewart.crash.03/ Smith, Ray.

No definitive evidence exists that indicates the rate at which the accident flight lost its cabin pressure; therefore, the Safety Board evaluated conditions of both rapid and gradual depressurization. Planes have two types of oxygen bottled oxygen used in masks during emergencies and bleed air that comes off the engines and is pumped into the cabin so passengers have enough oxygen, even as the plane climbs higher and the air outside thins. The data made public on Wednesday also include testimony that the Central Florida charter company that owned the jet had slipshod record keeping and could not produce the planes most recent maintenance logs that might have helped determine what caused the crash. In summary, the Safety Board was unable to determine why the flight crew could not, or did not, receive supplemental oxygen in sufficient time and/or adequate concentration to avoid hypoxia and incapacitation.[2]. Nov. 28, 2000 -- After a yearlong investigation, investigators say they are unable to pinpoint exactly what caused the crash that killed golf champion Payne Stewart and five others last year. They have not said whether they think the air pressure dropped suddenly to levels that dont provide enough oxygen for humans to survive, or whether a slower loss of pressure happened but wasnt corrected by the pilots. commercial flight from Orlando to Dallas.

The reasons remained unknown because the plane was "shredded," the government official said. The jet continued on its ghostly flight, apparently controlled by autopilot, before running out of fuel and crashing in a South Dakota field with over 100 times the force of gravity. In final report of NSTB, the National Transport Safety Board said the airplane was not equipped with a flight data recorder, an invaluable tool in most major investigation, and it had only 30-minutes of voice recorded in the cockpit. macromolecules. Hypoxia can result from a failure, at any stage, in the delivery of oxygen to cells.
