US nearly detonated atomic bomb in 1961: file
One of the bombs began to detonate — a single switch was all that stopped it from doing so. The three other safety mechanisms designed to prevent an unintended detonation failed.
The US government has acknowledged the accident before, but the 1969 document is the first confirmation of how close the United States came to nuclear catastrophe on that day.
“It would have been bad news in spades,” wrote its author, US government scientist Parker F. Jones.
The bomb was 260 times more powerful than the one that devastated Hiroshima in 1945, according to the Guardian.
The accident happened at the height of the Cold War between the United States and the Soviet Union.AFP
