Narrative:
Mosquito PF657: Took off for Ferry flight from 51MU RAF Fradley bound for RAF Benson. 29/07/1947
In flight, port engine failed and then starboard engine lost power; aircraft bellylanded at RAF Upper Heyford, Oxfordshire after 'engine out' glide approach.
Accident Investigation Report. The aircraft had been improperly stored with 100 octane aviation fuel in the tanks and that this had "attacked" (dissolved) the bullet-proof inner lining of the tanks. A resultant thick, brown "goo" passed to the carburetors, eventually blocking the jets and causing the engines to stop.
