Design & Development
The Schweizer SGU 1-19 and Schweizer SGU 1-20 are a family of United States single-seat, high-wing, strut-braced, utility gliders built by Schweizer Aircraft of Elmira, New York.
The 1-19 was a 1944 development of the pre-war SGU 1-7 and bears a strong resemblance to the earlier craft. It was designed for single place training and soaring flights.
The 1-20 was an improved version of the 1-19 with a wingspan of 43 feet (13 m) replacing the 36-foot (11 m) wing on the 1-19.
