Last remaining Minuteman silo site off I-90 in S.D. We go on short tour here, in the middle of nowhere.

It's the last silo from the 150 missiles that used to be clustered in southern S.D. Something like 450 MM still active.

Best attempt to capture training missile in silo thru glass.

Sense of the cap that would track off to left to uncover silo.

Missileer explains launch procedure.

This guy the only man to actually launch Minuteman from U.S. soil in '65 test.
