Narrative:
Handley Page Halifax B. Mk. VII NA398, 21 HGCU (Heavy Glider Conversion Unit): Written off (damaged beyond repair) 12 July 1946 in a landing accident at RAF Leconfield, Beverley. East Yorkshire.

The crew was engaged in a demonstration flight at RAF Leconfield and was performing an exercise consisting to prove the aircraft was able to fly with only one engine operative. While cruising at low height in the vicinity of the airbase, the crew shut down three engines and continued to fly on one engine only when the aircraft lost height, stalled and crashed in a field located near the airfield. While all six crew members were rescued, the aircraft was damaged beyond repair. The only crew member identified by name (so far) is the pilot, Flying Officer J G Calvert.

Causes: Several procedures were neglected by the crew who was performing the demonstration flight at a too low altitude. Due to an insufficient distance between the aircraft and the ground when three engines were shut down, the crew was unable to regain control after the aircraft stalled.
