Refuelers keep aircraft flying during exercise
Staff Sgt. Ron Davis, a KC-135 Stratotanker boom operator with the 507th Air Refueling Wing at Tinker Air Force Base, Okla., keeps the boom steady while refueling a U. S. Navy F/A-18F Super Hornet over the waters of Hawaii July 20, 2010, 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)
