What happened
The incident occurred while the crew was conducting a night training exercise originating from RAF Llandwrog (Caernarfon). During the flight, the aircraft was operating at an altitude of 6,000 feet under conditions of poor visibility. The crew encountered turbulence and had obtained permission to descend when the twin-engine aircraft struck the north slope of Mt Moel Hebog, located southwest of Beddgelert.
The impact resulted in significant casualties among the five occupants on board. Four individuals were killed in the crash, while one crew member survived with injuries. The fatalities included the pilot, navigator, and two wireless operators/air gunners. The sole survivor was the air bomber.
