The Schweizer SGS 1-23, first flown in 1948, is a single-seat American sailplane with dual classification as open-class or standard-class (1-23H-15 variant). Measuring 6.2 meters long with a 16.1-meter wingspan, this aircraft emerged during the post-war American glider resurgence. The 1-23 established the Schweizer name in competitive soaring through proven durability and respectable performance. Its straightforward design and accessible handling characteristics made it popular in training and recreational operations throughout North America.
