U.S. Air Force Tech Sgt. John Moler, a crew chief assigned to the 169th Aircraft Maintenance Squadron of the South Carolina Air National Guard, directs the pilot of an F-16 Fighting Falcon fighter jet during “hot-pit” ground refueling training on the flight line at McEntire Joint National Guard Base,S.C., Feb. 7, 2016.  Ground refueling while the engine is running, allows aircraft to return to flight quickly during sortie operations and combat missions. (U.S. Air National Guard photo by Senior Airman Ashleigh S.
