Mounted on the back of Boeing 747, the Space Shuttle Enterprise takes off on its first crewed flight, the first of three “captive-active” flights which see Enterprise remain in place on its carrier aircraft. For the first time, Enterprise’s computers, avionics and other flight systems are powered up in a full-up, hour-long dress rehearsal of an eventual free-flight landing test at 15,000 feet. The first crew of the Space Shuttle Enterprise consists of astronauts Fred Haise and Gordon Fullerton.
