The aircraft failed to recover from a spin, and was destroyed on impact with the ground. Examination of the wreckage revealed that the wheel brakes had been applied after takeoff, and that this prevented the pilot from using the full rudder movement during spin recovery.

Squadron Leader Ian Lewis McGregor Hallam, RAF (pilot, aged 32): Commanding Officer of Aberdeen University Air Squadron at the time
Cadet Pilot John Lawrie (Pupil pilot under instruction, aged 19)
