NASA Shuttle Carrier Aircraft Arrives at Kennedy Space Center

NASA's Shuttle Carrier Aircraft (SCA), a modified 747 jumbo jet, touched down just before 4 p.m. EDT on Tuesday at the Shuttle Landing Facility (SLF) at the agency's Kennedy Space Center in Florida. The SCA, which is designated NASA 905, was the original shuttle carrier and was used in 1977 for the space shuttle approach and landing tests. This series of eight captive and five free flights with the orbiter prototype Enterprise, in addition to ground taxi tests, validated the aircraft's performance as an SCA, in addition to verifying the glide and landing characteristics of the orbiter configuration — paving the way for orbital flights and ferry flights. NASA 905 now will fly the final ferry flight in Space Shuttle Program history.
