Keno Air Force Station was a BUIC site in the 25th Air Division. A BUIC site was designed to take over in the event that the SAGE center was nuked during a war. In 1973 we had two Greyhound busloads of people come up to run the site and man the computer scopes (scopes which saw the whole division, and used a light-gun to select a target). When I left in 1976, we all came up on one half-empty greyhound, or even a station wagon for night shifts. The BUIC design pretty much was obsolete when the MIRV nuclear capability wiped out any redundancy advantage.
