Refuelers keep aircraft flying during exercise
Maj. Benjamin Evans, a KC-135 Stratotanker pilot from the 507th Air Refueling Wing at Tinker Air Force Base, Okla., along with maintainers from the wing's 507th Maintenance Squadron, conduct a walk-around inspection of a tanker July 20, 2010, before departing Joint Base Pearl Harbor-Hickam, Hawaii, to refuel aircraft participating in 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. (U.S. Air Force photo/Tech Sgt. Cohen A. Young)
