Building 105 in Area A of Los Angeles AFB, as it appeared during the 1960s and early 1970s. Command Section offices have always been on the sixth floor of Building 105. The Thor Agena launch vehicle in front of the building, a local landmark for many years, was toppled by a gust of wind on 25 March 1975.
