The firm Glasflügel () was founded by Eugen Hänle in 1962 and was located in Schlattstall, south of Kirchheim unter Teck. It was the first firm to manufacture a glass-fibre sailplane in large numbers. It was also responsible for a large number of innovations in sailplane design and technology: quick assembly systems for wings and tailplane, automatic control connections, trailing edge airbrake-flap combinations, hinged instrument panels, the parallelogram control stick and automatic trimming are some innovations introduced by Glasflügel and later adopted by other manufacturers. Some of these are standard features in nearly all gliders produced today.
Glasflügel encountered financial difficulties in the 1970s which led to a co-operation with the firm Schempp-Hirth starting from May 1975. The death of Eugen Hänle in a flight accident on September 21 of the same year further aggravated the company's position, and after further changes in ownership in 1979, it was finally dissolved in 1982.
