On March 12th 1953, Avro Lincoln RF531 took off from the Central Gunnery School at RAF Leconfield in Yorkshire on a routine flight, flying between Hamburg and West Berlin along a 20 mile-wide corridor over Soviet-contolled East Germany. An apparent navigational error took them briefly out of this corridor, gaining the attention of two MiG-15 which fired upon the bomber, causing her to spiral out of contol and crash. All seven crewmen were killed.
