The first flight of NASA’s Boeing 747/Shuttle Orbiter composite took place from the Dryden Flight Research Center, California, on February 18, 1977. The 584,000lb combination took off from the Rogers Dry Lake runway after a 6,000ft roll at 8.30 a.m. local time, climbed to 16,000ft and flew a race-track course over the Mojave Desert for 2hr at a maximum speed of 250kt. A series of gentle manoeuvres were made checking behaviour at circuit speeds and investigating flutter response. At present, the Orbiter’s engines are faired to reduce buffet.
