Titan II Missile Site

I went to this today. It was Great!

Top-to-Bottom Tours

You'll explore all 8 levels of the underground silo, from level 1 where you'll view the silo closure door opening mechanism, to level 8 more than 140 feet underground where you'll see the propellant pump rooms.

Other stops include silo level 3 where you'll see the massive diesel generator, and silo level 7 where you'll enter the launch duct and stand directly underneath the missile.
