The 3251st Flying Training Squadron located at Randolph AFB, TX phased down pilot instructor training during 1967 so it could begin to provide UPT to meet pilot production needs for Vietnam. The T-37 pilot instructor training program at Randolph transferred to Perrin AFB, Texas, in July 1967, where it was operated by the 3251st Flying Training Squadron, which ATC had organized on 1 April 1967. This is a reproduction of that squadron patch and does not come with velcro attached.
