A C-5M and C-5A Super Galaxies sit on the runway at night Sept 19, 2013, at Dover Air Force Base, Del. The C-5M is an upgraded version of the C-5 with new engines and modernized avionics designed to extend its life beyond 2040. The full moon not only made for a well-lit night on the flight line, it also illuminated the astonishing upgrades and features of the C-5M. (U.S. Air Force photo/David Tucker)
