Space Shuttle Discovery Flyover

The Shuttle Carrier Aircraft (SCA) is a extensively modified Boeing 747 airliners that NASA uses to transport Space Shuttle orbiters.


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 are placed on top of the SCAs by Mate-Demate Devices, large gantry-like structures that hoist the orbiters off the ground for post-flight servicing, and then mate them with the SCAs for ferry flights.
