Founded by Eugen Hänle in 1957, the Glasflügel Company was located in Schlattstall, to the south of Kirchheim unter Teck. The dragonfly (Libelle) was the original logo and is still instantly recognised as Glasflügel today.

Sadly, the founder, Eugen Hänle, was killed in an tow plane accident September 21, 1975. Ursula started her own company in 1968 called Start & Flug, she is well known for designing and building the Salto, supported by her husband. To this day, she is the only female to design and build a glider. She passed away April 1, 2009.

In 1964, Glasflügel started the large-scale production of the Open Libelle (H 301), a 15m glider with wing flaps, which achieved performances far ahead of others in the newly created 15 m class in 1975. A total of more than 100 gliders of this type were produced between 1964 and 1969. This was the first time a fiberglass aircraft construction was mass produced! Other well known glider types were also built by Glasflügel, e.g. Standard Libelle, BS1, Kestrel, Glasflügel 604, Club Libelle, Hornet, Mosquito, Glasflügel 304 and Glasflügel 402. There were also prototypes; the 202, 203 and 204 which led to the development of the Club Libelle and Hornet.

Interesting, but incomplete were the two seater with side by side seat projects, the Glasflügel 701 and 704. It was conceived with a double wheel undercarriage, T-shaped elevator with a stabiliser, flaps divided into three sections over a wingspan of 19 meters for the Glasflügel 701 and 22 meters with a surface area of 18,76m² for the Glasflügel 704. On January 8, 1981, Hanko Streifeneder started the construction of the Falcon, working in his spare time at the Glasflügel factory, which became an advanced standard class glider (Hanko is pictured below). The calculations and measurements were carried out by Martin Hansen, another Glasflügel employee at the time. Hanko made the first testing flight in Braunschweig July 7th 1981, and it is a glider he still enjoys flying today.

After the bankruptcy of Glasflügel, Hansjörg Streifeneder was passionate about preserving the work of Eugen Hänle and continued with the maintenance and certification of all Glasflügel gliders. He founded the Glasfaser Flugzeug-Service GmbH. He worked in the old Glasflügel facilities for a short time, but soon new facilities in Grabenstetten, where the business still operates from today. In the first years he concentrated on maintenance, surface finishing, service and repair work of Glasflügel gliders, and also repairs and maintenance of gliders from other manufacturers.
