A NASA aircraft arrives at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. It will serve as a weather pathfinder, flying ahead of the space shuttle Endeavour, mounted atop NASA's Shuttle Carrier Aircraft, or SCA, during its ferry flight to California.

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.
