I'm watching the old 1983 movie quot;War Gamesquot; and I was wondering about the launch simulation. I can see them running near reality simulations, but do they go as far as opening the silo launch doors, as well as topping off the propulsion tanks?
Yes. They are still alive.
My father was posted in a missile silo with a Titan II nuclear warhead on it. He told me that at one point in 1968 they conducted a test where as the doors were opened and the keys we all in (3 keys in total) but that's as far as it went.
