Workers watch the arrival of space shuttle Endeavour at the Shuttle Landing Facility after the shuttle was towed from the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Endeavour was towed to the Mate-Demate Device, or MDD, where the shuttle will be lifted and connected to the top of NASA's Shuttle Carrier Aircraft SCA, a modified 747 jetliner. The shuttle has been fitted with an aerodynamic tailcone for its flight aboard the SCA to Los Angeles where it will be placed on public display. Photo credit: NASA/Kim Shiflett
