Missile complex interior
On Earth, missile complexes were part of the military infrastructure associated with World War III. After the war, Dr. Zefram Cochrane re-utilized one such site in Montana as a launch facility for his his Phoenix ship, itself a modified nuclear missile. (Star Trek: First Contact)
U.S.A.F. markings within the complex would seem to suggest that this facility was originally owned by the United States Air Force.
