Greece, US take interoperability to the skies during training
U.S. Air Force Master Sgt. Andrew Hogan, fuels manager assigned to the 52nd Expeditionary Logistics Readiness Squadron, observes an F-16 Fighting Falcon fighter aircraft being refueled on the flightline during a flying training deployment at Souda Bay, Greece, Jan. 30, 2015. The hot pit refueling process involved pumping engine fuel into an aircraft as its engine still runs, enabling it to continue flying operations with minimum interruption.
