- 1958 RAF Greenham Common accident (no image)
1958 RAF Greenham Common accident: a B-47E of the 310th Bomb Wing developed problems shortly after takeoff and jettisoned its two 1,700 gallon external fuel tanks. They missed their designated safe impact area, and one hit a hangar while the other struck the ground 65 feet (20 m) behind a parked B-47E. The parked plane, which was fuelled, had a pilot on board, and was carrying a 1.1 megaton (4.6 PJ) B28 nuclear bomb, was engulfed by flames. The conflagration took sixteen hours and over a million gallons of water to extinguish, partly because of the magnesium alloys used in the aircraft. Although two men were killed and eight injured, the US and UK governments kept the accident secret: as late as 1985, the British government claimed that a taxiing aircraft had struck a parked one and that no fire was involved. Two scientists, F. H. Cripps and A. Stimson, who both worked for the Atomic Weapons Research Establishment at Aldermaston, stated in a secret 1961 report, released by the CND in 1996, that the fire detonated the high explosives in the nuclear weapon, that plutonium and uranium oxides were spread over a wide area (foliage up to 8 mi (13 km) away was contaminated with uranium-235) and that they had discovered high concentrations of radioactive contamination around the air base.[4] However, a radiological survey commissioned in 1997 by Newbury District Council and Basingstoke and Deane found no evidence of a nuclear accident at Greenham Common, suggesting that Cripps and Stimson's statements were false.
