A U.S. Air Force pilot from the 14th Fighter Squadron refuels from a KC-135 Stratotanker in an F-16 Fighting Falcon for refueling during a defensive counterair mission over the Pacific Ocean Feb. 27, 2018. While the F-16 does not typically allow for hours-long flights, in-air refueling extends the pilot’s ability to continue operations without having to land and refuel. (U.S. Air Force photo by 1st Lt.
