Royal Air Force — Flight RF531

A Royal Air Force Avro Lincoln B.2 was intercepted and shot down by two Soviet MiG-15 fighters while flying through an air corridor toward West Berlin. The aircraft, which was on a routine training flight from RAF Leconfield, was struck by 23mm cannon fire, causing it to catch fire and disintegrate. All seven crew members were killed, including three who reportedly bailed out but were either strafed in their parachutes or died of their injuries. The incident occurred near the border of the British and Soviet occupation zones in Germany, sparking a major diplomatic crisis during the Cold War.

Report

Investigation Summary

The flight was part of a fortnightly routine mission conducted by the Central Gunnery School. The Lincolns typically flew from East Yorkshire to West Berlin via designated air corridors, often serving as targets for mock interceptions by NATO fighters. On this occasion, the aircraft was intercepted by Soviet fighters near Boizenburg. According to British accounts, the Lincoln was unarmed, with its guns replaced by cameras for training evaluation. The Soviet Union claimed the aircraft had violated East German airspace, ignored orders to land, and initiated fire against the interceptors. However, an RAF inquiry concluded that while the aircraft had accidentally strayed off course into the Soviet zone, it had returned to the British sector and was over the border in the British zone when the attack commenced. The crippled aircraft subsequently crashed just inside the Soviet zone near the Elbe river. The wreckage fell in the Soviet zone, and the bodies of the crew were later returned to British authorities. The incident remains the only instance of a British military aircraft being destroyed by the Soviet Union during the Cold War.

Final Conclusions

The RAF inquiry determined the primary cause was a hostile shootdown by Soviet MiG-15 fighters. While the aircraft had likely strayed from its intended flight path into Soviet-controlled airspace, the use of lethal force against an unarmed training aircraft was condemned by the British government as a barbaric act. The Soviet claim that the Lincoln fired first was refuted by the RAF, noting the aircraft's guns were not loaded.
