F-35 Refueling
An F-35A Lightning II approaches a KC-135 Stratotanker during aerial refueling May 13, 2013, near Eglin Air Force Base, Fla. The initial cadre of Air Force F-35 instructor pilots at the 33rd Fighter Wing recently qualified in aerial refueling for the joint strike fighter. The 33rd FW is responsible for F-35 A/B/C Lightning II pilot and maintainer training for the Marine Corps, the Navy, the Air Force and, in the future, at least eight coalition partners. The KC-135 is assigned to the 336th Air Refueling Squadron, March AFB, Calif. (U.S. Air Force photo/Master Sgt. John Nimmo)
