The Falcon is a standard class glider, which was completed in 6 months of construction (8 January to 7 July 1981) by Hanko Streifeneder in his spare time on the Glasflügel premises.

The necessary calculations and verifications were carried out by Martin Hansen, who was also working at Glasflügel at the time. The wing profile HQ-21/17.15 comes from the Braunschweig aerodynamicists Karlheinz Horstmann and Armin Quast.

Completely new was the wing ground plan, a rectangular double trapezoid. The fuselage and tail units of the Falcon came from the Glasflügel 402, the last aircraft of the traditional company from Schlattstall.

The first flight was carried out by Hanko on July 7, 1981 in Braunschweig, and he still enjoys flying it today.
The moulds of the Falcon went first to Glaser-Dirks, and the wing of the DG-300 was based on the Falcon, and later to the Akaflieg Karlsruhe, where the wings of the two AK-5 were built in the Falcon forms.
The Falcon was measured in August 1981 in Aalen and is still one of the highest performing gliders in standard class.
