An RAF Avro Lancaster crashed shortly after takeoff from Marston Moor during an air gunnery exercise, killing all ten crew members on board.

What happened

The aircraft was operating out of RAF Marston Moor as part of a training mission involving coordination with a Royal Air Force Spitfire. The incident occurred shortly after the plane left the ground while in the initial climb phase. During this ascent, the pilot executed a sharp turn and subsequently lost control of the airframe. The aircraft entered an uncontrolled dive and impacted the terrain in a field situated approximately 800 metres from the airbase perimeter. The impact resulted in a significant explosion that completely destroyed the Avro Lancaster. All 10 crew members aboard were killed in the accident.

Findings

Investigations into the crash identified the immediate cause as a loss of control during the initial climb. This loss of control was attributed to the failure of the tail section. The underlying reason for this structural failure is believed to have been a pre-existing structural issue with the aircraft.

Probable cause

Loss of control in initial climb caused by the failure of the tail section, possibly due to a structural defect.
