1999 South Dakota Learjet crash

On October 25, 1999, a chartered Learjet 35 was scheduled to fly from Orlando, Florida, to Dallas, Texas. Early in the flight, the aircraft, which was climbing to its assigned altitude on autopilot, quickly lost cabin pressure and all six on board were incapacitated due to hypoxia - a lack of oxygen. 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. The plane ran out of fuel ov ...

According to the official Air Force report, the aircraft experienced an uncontrolled decompression that required it to descend to 10.000 feet in order to lower the cabin altitude. Increased fuel consumption caused by having to fly at lower altitude, combined with the inability to rendezvous with a tanker in time caused the aircraft to run ou ...
