"This overhead view is of Atlantis atop a modified 747 as the craft flew
over California's high desert. Atlantis and the crew of the STS-125 mission
landed at Edwards Air Force Base on May 24, 2009, and departed Edwards on
the journey home via ferry to the Kennedy Space Center in Florida on Monday,
June 1, 2009. The shuttle landed safely the following day at 6:53 p.m. EDT.
