What happened
A flight traveling from Madrid-Barajas toward the Fürstenfeldbruck airbase west of Munich crashed while traversing the Swiss Alps. At approximately 14:55 local time, the aircraft was cruising at 9,000 feet, and the radio operator had recently reported the plane's position to ground control as being three kilometers south of Dijon.
Following this communication, the aircraft drifted eastward toward the Swiss Alps. The plane eventually struck a mountain slope near the Guggi Glacier. After the flight failed to reach its intended destination, the US Air Force station in Frankfurt-Main AB notified Swiss authorities that the aircraft was missing. Search and rescue efforts led by local residents eventually located the wreckage at an altitude of 3,000 meters one day later.
The impact destroyed the aircraft and resulted in eight fatalities, with no survivors among the crew or passengers.
Findings
The investigation determined that the crash was the result of a navigation error committed by the flight crew.
