The 25th Flying Training Squadron is part of the 71st Flying Training Wing based at Vance Air Force Base, OK. It operates Northrop T-38 Talon aircraft conducting flight training. The squadron has provided Undergraduate Pilot Training (UPT) for active duty, Air National Guard, Air Force Reserve, and selected foreign allies since 1 November 1972. I found this patch in a Korean embroidery shop. It has the “theater-made” feel with the ‘cut’ edge, and does not have velcro attached.
