Arctic refueling
Four A-10 Thunderbolt IIs fly in formation behind a KC-135 Stratotanker April 4 over the Pacific Alaska Range Complex. Nearly all internal fuel, approximately 200,000 pounds, can be pumped through the flying boom, the KC-135's primary fuel transfer method. The A-10s are from the 355th Fighter Squadron, and the KC-135 is from the 168th Air Refueling Squadron, all from Eielson Air Force Base, Alaska. (U.S. Air Force photo/Master Sgt. Robert Wieland)
