@johnefrancis Well, there were at least two incidents where the warhead was accidentally launched off the missile. Best known is the Damascus incident where a worker dropped a socket, causing a Titan missile to eventually explode, flinging the warhead hundreds of feet. There was also an incident where a worker was debugging the Minuteman silo security system. He pulled a fuse, bizarrely causing a retrorocket in the missile to ignite, flinging the warhead off the missile and it dropped 75 feet to the bottom of the silo.
