Ground crewmen on the ramp at NASA’s Dryden Flight Research Center on Edwards Air Force Base, Calif., are dwarfed by two of NASA’s highly modified Boeing 747s. In the foreground is the Stratospheric Observatory for Infrared Astronomy 747SP housing a 17-ton, high-tech German-built infrared telescope. To the rear is one of NASA’s two Shuttle Carrier Aircraft modified to return space shuttles to the NASA Kennedy Space Center after an unexpected shuttle landing at Edwards.March 14, 2011
