Only recently has the US Air Force given him permission to tell the tale, which, if borne out as true, would constitute a terrifying addition to the lengthy and already frightening list of mistakes and malfunctions that have nearly plunged the world into nuclear war.

The story begins just after midnight, in the wee hours of October 28, 1962, at the very height of the Cuban Missile Crisis. Then-Air Force airman John Bordne says he began his shift full of apprehension. At the time, in response to the developing crisis over secret Soviet missile deployments in Cuba, all US strategic forces had been raised to Defense Readiness Condition 2, or DEFCON2; that is, they were prepared to move to DEFCON1 status within a matter of minutes. Once at DEFCON1, a missile could be launched within a minute of a crew being instructed to do so.
