Check with your dad about a fire in a Titan missile silo under construction, I think the date was September 1964/1865. There was no missle in the hole but the cause of the fire was a dropped wrench. Sounds as if some of the facts about that accident and the one in 1980, that you reported, are mixed up. I vividly remember the explosion that was reported as in the 80s that blew the door off and the warhead landed close by but I don't think the date is right. The blast in the 60s killed over 50 people, including the uncle of a girl I was working with, all the loss of lives involved civilian construction workers.

Now you can buy a silo, I think someone converted one into a house, the birds are long gone of course. We think the world was a dangerous place now!
