The documentary Command And Control sounds very interesting. There is also a book about the incident in a Titan II missile silo which set off a chain of events that would put the United States Air Force to the test back in 1980.
I have actually been in a Titan II missile silo that was decommissioned and turned into a museum. It was several years ago but, I can still remember the feeling that I got standing in the control center or in the missile silo itself. It was a feeling of going back in time and what a great responsibility the men and women of the Air Force must have had that worked at these missile sites knowing that one day they may get the launch instructions and codes that would send one of these missiles into Russia.
