After a three-day trip from California, the shuttle carrier aircraft, or SCA, and its piggyback passenger space shuttle Endeavour fly through cool, blue skies over the Shuttle Landing Facility runway at NASA's Kennedy Space Center in Florida. Touchdown at Kennedy was at 2:44 p.m. EST. The SCA is a modified Boeing 747 jetliner. Endeavour landed at Edwards Air Force Base in California Nov. 30 to end mission STS-126. The return to Kennedy began Dec. 8 and took four days after stops across the country for fuel. The last stop was at Barksdale Air Force Base in Shreveport, La. Weather conditions en route and in Florida postponed the landing at Kennedy until Dec. 12. Photo credit: NASA/Tim Jacobs
