Glaser-Dirks DG-500M
The two-seat Glaser-Dirks DG-500, which first flew on 19 March 1987, spawned the DG-500M variant, adding a retractable two-cylinder Rotax 535 engine behind the cockpit that lets the 22-metre-span glider launch itself and sustain flight without a tow. In 2006 a stripped DG-500M, its engine removed and replaced with liquid-oxygen bottles and pressure-suit equipment, carried Steve Fossett and Einar Enevoldson to 15,445 metres over Patagonia's mountain waves as the Perlan Project glider, at the time the highest a piloted, unpowered glider had ever flown. In everyday use, the same airframe served as a conventional two-seat trainer and competition glider for clubs worldwide.
