Refueling the Raptor
Tech. Sgt. Roger Braun, 909th Air Refueling Squadron boom operator, Kadena Air Base, Japan, prepares to lower the boom of a KC-135 Stratotanker over the Joint Pacific Alaska Range Complex during RED FLAG- Alaska 13-3 Aug. 14, 2013. Nearly all internal fuel, a maximum transfer load of approximately 200,000 pounds, can be pumped through the aircraft’s boom, a rigid, telescoping tube equipped with movable flight control surfaces that an operator controls.
