English: Orbiter "Enterprise" rides "piggy-back" atop NASA 747 carrier
The Orbiter 101 "Enterprise" sits in a piggyback configuration atop NASA 905, a 747 carrier aircraft, prior to takeoff on the fifth and final Approach and Landing Test (ALT) free flight mission from Dryden Flight Research Center (DFRC). Astronauts Fred W. Haise, Jr., commander, and C. Gordon Fullerton, pilot, later controlled the Orbiter during its two-mintue, one-second free flight and its landing - the first on a hard surface in the ALT series - at Edwards Air Force Base.
