However, without supplemental oxygen, substantial adverse effects on cognitive and motor skills would have been expected soon after the first clear indication of decompression (the cabin altitude warning), when the cabin altitude reached 10,000 feet (3,000m) (which could have occurred in about 30 seconds). He also had Air Force experience flying the KC-135 and Boeing E-3 Sentry. 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. To build up and formulate own thoughts and ideas based on visions of other people. [2], At 13:27:13 UTC, the air traffic controller from the Jacksonville Air Route Traffic Control Center (ARTCC) instructed the pilot to climb and maintain flight level (FL) 390 (39,000 feet (11,900m) above sea level).

The aircraft continued climbing past its assigned altitude, then failed to make the westward turn toward Dallas over North Florida and continued on its northwestern course, flying over the southern and midwestern United States for almost four hours and 1,500 miles (2,400km). NTSB Board presentation Arkansas woman indicted for selling stolen body parts to Pennsylvania man (interstage turbine temperature) split at altitude and cabin at its Wichita (KS), facility indicated the following: Cabin pressure follows throttles - 2,000 feet bump both The agency will release an analysis later in the year on the cause of the crash that killed Stewart, two pilots and three other passengers Oct. 25, 1999. Research has shown that a period of as little as 8 seconds without supplemental oxygen following rapid depressurization to about 30,000 feet (9,100m) may cause a drop in oxygen saturation that can significantly impair cognitive functioning and increase the amount of time required to complete complex tasks.
