Shuttle Carrier Aircraft

Atlantis being mated to SCA N911NA at Dryden Flight Research Center

Columbia atop SCA N905NA, flying by the Vehicle Assembly Building (VAB) at Kennedy Space Center (KSC), 1990. N905NA no longer has American Airlines' pinstriping.

The Shuttle Carrier Aircraft (SCA) were two extensively modified Boeing 747 airliners that NASA used to transport Space Shuttle orbiters. One is a 747-100 model, while the other is a short range 747-100SR.

The SCAs were used to ferry Space Shuttles from landing sites back to the Shuttle Landing Facility at the Kennedy Space Center, and to and from other locations too distant for the orbiters to be delivered by ground transport. The orbiters were placed on top of the SCAs by Mate-Demate Devices, large gantry-like structures that hoisted the orbiters off the ground for post-flight servicing then mated them with the SCAs for ferry flights.
