Capt. Michael Bargiel, 8th Airlift Squadron pilot, approaches a KC-10 Extender from the 349th Air Mobility Wing at Travis Air Force Base, Calif., to begin aerial refueling during a local training mission March 8, 2012, above Yakima Training Center, Wash. Although the KC-10's primary mission is aerial refueling, it can combine the tasks of a tanker and cargo aircraft by refueling fighters and simultaneously carry the fighter support personnel and equipment on overseas deployments.
