__NOTOC__

The SZD-9 "Bocian" (Polish: "Stork") was designed by Marian Wasilewski, with Roman Zatwarnicki and Justyn Sandauer as a multi-purpose two-seat sailplane capable of fulfilling the needs of every area from training to competition flying.

The prototype SZD-9 flew for the first time on 10 March 1952. An improved model was accepted for a production as SZD-9bis Bocian-1A (or simply "Bocian A"). The first serial glider flew for the first time on 13 March 1953 and 11 were built.

Apart from use in Poland, the type was exported to 27 countries, including Austria, Australia, Belgium, China, France, Greece, India, Norway, East Germany, Switzerland, Tunisia, Turkey, Venezuela, United Kingdom, Soviet Union.
