Loadmasters from the 22nd Airlift Squadron monitor the tight clearances between the Pathfinder and the C-5C Galaxy’s rear opening as the cargo inches its way onto the ramp at Joint Base Andrews, Md., July 17, 2014. The 22nd ALS is from Travis Air Force Base, Calif., and operates the Air Force’s only C-model Galaxies, which are specially modified to carry NASA’s space equipment. (U.S. Air Force photo/Staff Sgt.
