The aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
Improper operation of brakes and/or flight controls and part of the pilot-in-command who failed to abort the takeoff procedure. Inadequate supervision of flight.

Circumstances:
The crew departed Floyd Bennett Field Airport in New York on a flight to Moffett Airbase, California, with an intermediate stop at Glenview Airport, Illinois, under call sign PE-05. At 2035LT, while cruising at an altitude of 22,000 feet, the crew informed ATC about his position. Shortly later, the airplane entered a spin, crossed the last cloud layer at an altitude of 3,000 feet in a right turn and struck the ground in a 60° nose down attitude at a speed of 800 km/h. The aircraft disintegrated on impact and all four crew members were killed. The wreckage was found seven miles northeast of Battle Creek.
Crew:
Lt William E. Xiques, pilot,
Lt John P. Fitzmaurice III, copilot,
ADJ2 Charles J. Lurvey, flight engineer,
ADJ3 Larry W. Battson, flight engineer.
Probable cause:
Investigations determined that there was no in-flight fire and no major structural failure had occurred. The plane was only about a year old at the time of the accident. The only clues were unintelligible voice transmissions at 2037 and again at 2039. The voice was masked by extreme high frequency background noise. Despite attempted computer analysis of the voice and an extended accident investigation, the cause was never determined. It was believed that some kind of catastrophic failure had occurred that incapacitated the crew. It was also surmised that it was possible that the windshield failed in-flight under decompression forces causing sound comparable to high velocity air in the cockpit. Not enough of the windshield was recovered to perform an analysis and come to any conclusions about this possibility.

Circumstances:
A Lear Jet Model 23, N804LJ, operated by the Lear Jet Corporation crashed eight miles east-northeast of Jackson, Michigan, at approximately 1935 e.s.t., on October 21, 1965. The pilot and copilot were killed. There were no passengers. The aircraft was destroyed by impact. The flight was operating in accordance with an Instrument Flight Rules flight plan from Detroit, Michigan to Wichita, Kansas, at an assigned altitude of Flight Level 250. The radar controller working the radar contact at 1933, and observed the target traveling in a southwest direction ". . . when the aircraft started a sharp turn to the right (i.e. north) (sic). As the aircraft passed through a northerly heading the beacon target disappeared from the radar." The aircraft was traversing an area of moderate to severe turbulence when it deviated from the assigned route.
Probable cause:
The Board determines that the probable cause of this accident was a loss of adequate attitude reference resulting from AC electrical power failure under night, turbulent conditions.

Probable cause:
Loss of control caused by the failure of a flap cable.
