The Schneider DFS 108-14 SG-38 Schulgleiter is a German high-wing, cable-braced, single-seat primary glider that was designed at the Schneider factory at Grunau in 1938, hence the designation. The SG-38 played a critical role in pilot training for the second-wave of urgently needed Luftwaffe pilots in the WWII. It is one of, if not the most produced glider ever.
