Shows Missilemen and B-52 Bomb Crews on alert. Also shown is the SAC airborne command post which for years flew at 30,000 feet 24 hours a day. Tells the story of how SAC keeps its resources, including KC-135 refueling tankers, on a high state of readiness in the height of the cold war. Positive control procedures for missile control crews are shown. Looks like this was done around 1964. Any better guess?

Starting with Scott Crossfield’s first powered flight in September 1959, this film tells the story of the incredible X-15. The aircraft set both speed and altitude records. Three X-15s were built in all, and they made a total of 199 test flights, the last one on 24 October 1968. The North American X-15 rocket-powered aircraft was part of the USAF/NASA/USN X-series of experimental aircraft. The X-15 set numerous speed and altitude records in the early 1960s, reaching the edge of space and bringing back valuable data that was used in the design of later aircraft and spacecraft. It could be considered the first manned suborbital spacecraft ever flown.
