Fuel for fighters
A KC-10 Extender from the 908th Expeditionary Aerial Refueling Squadron refuels a Tornado Dec. 11 over Afghanistan. Using either an advanced aerial refueling boom, or a hose and drogue centerline refueling system, the KC-10 can refuel a wide variety of U.S. and allied military aircraft within the same mission.
