Disappearance
The aircraft was participating in an international rally between the United Kingdom and Sydney, Australia. It departed from London on 19 December. While flying over the Alps, contact with air traffic control was lost. The aircraft failed to arrive at its next stopover, prompting search and rescue operations.
Search and Suspension
Search and rescue operations were initiated when the aircraft did not reach the scheduled stopover. However, after several weeks with no trace of the aircraft or its crew, the operations were suspended.
Wreckage Discovery
On 5 August 1970, walkers discovered the wreckage on the slope of a mountain near the Rocher de la Plassa, approximately 6 kilometers southeast of Courchevel. The aircraft was found with both occupants on board. Both occupants were killed.
Aftermath
The discovery ended the months-long mystery of the aircraft's disappearance. The wreckage location confirmed that the aircraft had crashed in the mountainous terrain. No further details about the aircraft type, registration, or operator were provided in the investigation source.
