I remember one Titan silo that we used to visit, had all of the superstructure from the missile silo itself removed. You would walk down a concrete corridor/tunnel from the control center to the silo, but it would end with nice long drop to the bottom, or to the doors 30' or so above.
One trick we would do would be to stand at the edge of the tunnel, and turn out all of the flashlights. Of course, it would get totally dark, and the knowledge that the next step would be into nothingness was a bit freaky. Most of the time I'd take a step backward just to be on the safe side.
