High Quality Content by WIKIPEDIA articles! The Schweizer SGM 2-37 is a two-place, side-by-side, fixed gear, low wing motor glider. A total of twelve were produced between 1982 and 1988, including nine for the United States Air Force Academy, which designated it the TG-7A. The TG-7A was retired from USAFA service in April 2003. The basic airframe was later developed into the SA 2-37A and B covert surveillance aircraft. Schweizer had flown a Schweizer SGU 1-19 as a motor glider in 1946 without putting the design into production. Later the company carried out a design study of a motorglider designated as the Schweizer 1-30, but no examples were built. A single motorglider prototype, the Schweizer 2-31 was completed, but no further motorgliders were built by the company until 1982.
