What happened
The incident involved a twin-engine aircraft operating out of RAF Halton. The crew was conducting a routine training sortie when the weather conditions became marginal. While cruising at altitude, the aircraft struck the slope of a hill situated approximately 12 miles south of Aylesbury.

Additionally, the crew did not fully utilize their available radio systems. At the time of the accident, maintaining radio contact with local air traffic control at RAF Halton was reported to be difficult.
