An F-35A Lightning II taxis during night flying operations at Hill Air Force Base, Utah, March 26, 2019. Night flying is required for pilots to sharpen their combat skills and maintainers work around the clock to prepare jets for flight, inspect them after flight, and get them ready for the next flying day. The 388th Fighter Wing is the Air Force’s first combat-coded F-35A wing. (U.S. Air Force photo by R. Nial Bradshaw)
