Royal Canadian Air Force CF-18 Hornets fly alongside a 22nd Air Refueling Wing KC-135 Stratotanker as the CF-18s each take turns refueling from a multi-point refueling system pod during exercise Amalgam Dart 15-2 May 29, 2015, over the Arctic Ocean. These pod modifications enhance the efficiency and flexibility of the Air Force's aerial refueling fleet, enabling KC-135s to refuel NATO and U.S. Navy aircraft. The KC-135 was from McConnell Air Force Base, Kan., and operated by a 92nd Air Refueling Wing crew from Fairchild AFB, Wash. (U.S. Air Force photo/Staff Sgt. Benjamin W. Stratton)
