a possible Russian plot to drop nuclear bombs on London during the Cold War has been revealed. The top-secret letter of a British atomic expert warning the authorities of a possible attack in 1954 has been shown for the first time, the Mirror has reported.
The National Archives released the handwritten letter from William Penney, an atomic bomb expert who died in 1991, which alleges a Russian attack was planned.
He told Atomic Energy Authority chairman Edwin Plowden that the bombs would fall on Croydon in south London, Uxbridge in the west and Romford in the east.
“Instead of using, say, 32 bombs on London, they would probably use three, four or five very powerful ones which would give the same total damage but need not be aimed accurately,” he wrote according to the Mirror.
