As during its first free flight test on 12 Aug 1977, it was launched mounted atop a Boeing 747 carrier, and separated from it in flight. Then it freely glided, on its own, in flight within the Earth's atmosphere. It touched down, landing like an airplane, on a dry lake bed in the Mojave Desert. Designated Orbiter Vehicle OV-101, it was a prototype built only for testing; it was never equipped for space flight.Its first inactive (no crew) captive flight test(18 Feb 1977) without separating from the carrier 747, was followed by five more inert captive flight tests, and three more active captive flight tests with crew aboard.«
