A U.S. Air Force veteran previously assigned to the 55th Fighter Squadron takes a picture while a 20th Fighter Wing maintainer tests the engine of an F-16CM Fighting Falcon at Shaw Air Force Base, S.C., Aug. 25, 2017. During the alumni tour, veterans received an opportunity to look inside an F-16 and experience its power during an engine run. (U.S. Air Force photo by Airman 1st Class Destinee Sweeney)
