About half an hour south of Tucson Arizona is a complete underground Titan missile complex from the cold war, preserved as a museum piece. It is fascinating to see this ancestor of the current Titan launch vehicle in its original habitat. A tour takes you through the underground launch complex and missile silo. The door to the silo is permanently blocked open with concrete, and the warhead area of the Titan in the silo has a hole in it to demonstrate that the missile is truly deactivated. More information about the museum is at http://www.pimaair.org/titan_01.htm
At the surface, they have the handling equipment for the two toxic propellants, nitrogen tetroxide (oxidizer) and a hydrazine blend (fuel). There is a refrigerated nitrogen tetroxide tank on a trailer, designed to contain the oxidizer whenever it was necessary to remove propellant from the missile. Coupled with the handling equipment is a large array of equipment designed to cope with spills.
An added bonus is a pair of completely accessible first and second stage Titan engines, positioned horizontally on ground level stands for viewing. I was not hassled when I walked right up to the engines and looked at them - my friend John Fee did the same, and took high resolution stereo-pair photos of the engines. Obviously, these engines, which once must have represented secret military technology, are no longer considered so.
