Narrative:Mosquito NT266: Took off at 11:00 hrs for a daylight training flight. 08/11/1946
During the flight, which saw them fly over the North Yorkshire Moors, the aircraft entered heavy cloud and the pilot lost control in cloud. The aircraft dived into the ground at high speed on Pockley Moor, five miles to the north of Helmsley, North and exploded leaving a large crater. Although never proven because of the destruction of the aircraft it was strongly suspected that the effect of icing had occurred on the aircraft's control surfaces and the pilot's ability to keep control of the aircraft was greatly reduced.
This icing effect also altered the aerodynamics of the wings of aircraft and often resulted in them entering an uncontrolled dive under certain cloud conditions.
The reasons for the crash are unknown. The aircraft was seen to enter thick cloud and then dived “head-on into the hill known as Pockley Moor with engines revving loudly.” (Earl, 1995) “strongly suspects” icing on the control surfaces would cause the pilot to lose control, while Earl suggests a downdraft or some structural problem with the aircraft. The aircraft nose-dived into the ground; “what was left in a deep, smouldering crater was more or less totally destroyed in the ensuing fire.
