Accident Synopsis
The aircraft was completing a return flight to its base at RAF Thorney Island after a rugby game at RAF Bovingdon. Departure occurred in poor weather conditions with low visibility due to snowfall. During the climb to a height of 400 feet, the pilot-in-command executed a left turn. The aircraft subsequently struck trees and crashed in a wooded area located five miles north of the airfield. One passenger sustained serious injuries, while the remaining 16 occupants were killed. The aircraft was destroyed upon impact, with only the rear part of the fuselage remaining intact.
Official Findings
The investigation was unable to determine the exact cause of the accident. Reported findings included low visibility due to snowfall, and that the aircraft was carrying one extra passenger beyond its 16-seat capacity. However, the extra passenger was not considered a contributory factor, and weather was not considered a factor. An assumption was made that the pilot was attempting to fly within sight of the ground in conditions of poor visibility.
