Warsztaty Orlik / XTG-7
Designed by Antoni Kocjan, the Orlik 2, which first flew in 1938, was a development of the 1937 14.4 m. Orlik 1. A special model (Orlik 3) was developed for the Olympic design competition for the 1940 games (won by the German D.F.S. Meise). It has unusual airbrakes on the wing undersurface, close to the leading edge, from the root to the wing bend. One example came to the U.S., and in WWII was imposed into the military as the XTG-7. Later, flown by Paul MacCready, it briefly held the world altitude record in 1948 at over 9,000 m. in the Sierra wave as well as winning the 1948 and 1949 U.S. Nationals.
