An F-22 Raptor from Elmendorf Air Force Base, Alaska, takes gas from a KC-135 Stratotanker July 27, 2010. By flying with a tanker, the fighter could routinely fill its fuel tanks to ensure it had enough fuel to reach a safe base in the event it had to land. The tanker is assigned to the 100th Air Refueling Wing at Royal Air Force Lakenheath, England. (U.S. Air Force photo/Staff Sgt. Austin M. May)
