South Carolina Air National Guard F-16 Fighting Falcon fighter jets taxi down the flight line to receive fuel during a “hot-pit” ground refueling exercise 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.
