NASA's Shuttle Carrier Aircraft, or SCA, is positioned beneath space shuttle Endeavour, suspended in the mate-demate device at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. The shuttle will be lowered and connected to the top of the SCA with the support of the device. The shuttle has been fitted with an aerodynamic tailcone for its upcoming ferry flight.

The SCA, a modified 747 jetliner, will fly Endeavour to Los Angeles where it will be placed on public display at the California Science Center. This is the final ferry flight scheduled in the Space Shuttle Program era. For more information on the shuttles' transition and retirement, visit http://www.nasa.gov/transition.
