Schweizer SGS 2-12


When aluminum became unavailable during World War II, Ernest and Paul Schweizer reworked the all-metal TG 2-8 (USAAC TG-2/ USN LNS-1) into a wooden sailplane. Besides being fabricated from wood, the wings were lowered from the 2-8’s shoulder position to a mid/ low mounting to improve rear seat visibility. The wing was thickened to allow cantilever construction and greater strenght for high speed aerotowing. Also upper and lower surface spoilers were used and the design simplified to ease of construction.

Harland Ross set an altitude record at 11,003 m / 36,100 feet in 1950, and Betsy Woodward held the feminine version of the same record.

One belongs to the National Soaring Museum. The Vintage Sailplane Association has the military manuals, color scheme drawing and paint chips.
