The crew of a 6th Air Refueling Squadron KC-10 Extender from Travis Air Force Base, Cali. work in unison while flying over the Atlantic Ocean during Exercise Ultimate Reach, Nov. 4, 2015. The mission involved eight KC-10s meeting seven C-17s over the Atlantic, refueling in a large formation overnight. The KC-10s offloaded on average 6,000 gallons of fuel into each C-17, who were then able to continue on across the Atlantic, drop more than 500 airborne troops in Spain.
