"Between mid-1969 and late 1972, Air Force Systems Command testing of MiGs was conducted by the 6512th Test Squadron of the Special Projects Branch, part of the Air Force Flight Test Center at Edwards Air Force Base. The original organization consisted of the HAVE FERRY MiG-17 and one test pilot, Major Norman L. Suits, and six maintenance personnel, and the MiG was a part-time or additional duty effort that took place at Groom Lake. But then the MiG-21 previously used in HAVE DOUGHNUT returned to the Test Site [Groom Lake] in 1972 when a new engine became available, and another pilot, Major Charles P. “Pete” Winters, was added. The program grew slowly and the number of daily sorties increased to as many as four flights in a single day. A MiG-17PF [Fresco D] arrived around the same time, as did several more MiG-21 airframes, from which a single MiG-21 was made flyable using parts from all of them. The rest were kept as a source of spare parts. [The Air Force now had a total of two MiG-21F-13s Fishbed C/Es, and two MiG-17F Fresco C/Ds.]"
"The AFSC group called themselves the “Red Hats” and in 1973 they came up with a unit emblem. It featured a bear wearing a wide-brimmed red hat and surmounting a globe hemisphere, all against a yellow background. Six red stars arced over the top. Two tabs included the name, “RED HATS,” and the motto, “MORE WITH LESS.” The motto symbolized the team’s ability to consistently produce useful data despite the challenges of operating from a remote location with a small cadre, and having to scrounge or make spare parts to keep their aircraft flyable."
