Refuelers keep aircraft flying during exercise
A U.S. Navy EA-6 Prowler flying over Hawaiian air space July 20, 2010, moves into position to receive fuel from a KC-135 Stratotanker from the 507th Air Refueling Wing at Tinker Air Force Base, Okla., during the Rim of the Pacific exercise. RIMPAC, the world's largest maritime exercise, is a biennial event which stresses interoperability among the 14 nations participating in the exercise. The tanker is staging out of Joint Base Pearl Harbor-Hickam, Hawaii. (U.S. Air Force photo/Tech Sgt. Cohen A. Young)
