October 27, 1962. A Soviet submarine was being bombed with depth charges by US warships who had detected the submarines presence in waters off Cuba.
In the emergency the Soviet submarine Captain ordered a torpedo attack on the American warships. Problem was, the torpedo's were fitted with nuclear warheads. The submarine could not contact Moscow for authorisation. The emergency procedure was that the three senior officers had to make the authorisation. The Captain and one other senior officer agreed to blast the US ships out of the water. They turned to the second in command Vasily Alexandrovich Arhhipov for his agreement. He thought a few moments longer ... and said No!
Can you imagine what would have transpired if he had said, Yes?
The British BBC is making a film of the incident - look out for it.
