The Hampden had taken off from RAF Finningley on a night navigation exercise. The aircraft crashed on Rushup Edge near Chapel-en-le-Frith, Derbyshire at around 20:15 killing all 4 crew.
The official inquiry determined that the aircraft was 50 miles west of its intended track and was flying too low. A contributory factor may also have been due to poor definition between the low cloud and the snow-covered ground.
The crew were:
83259 Pilot Officer M HUBBARD RAFVR Pilot (Aged 20)
590585 Sergeant K W B PERKINS RAF Navigator (Pilot) (Aged 24)
648240 Sergeant D W SMITH RAF Wireless Operator/ Air Gunner (Aged 19)
553939 Sergeant D J DAVEY RAF Air Gunner (Aged 18)
