The DG-500 once held the all-time altitude record for manned gliders, at 15,460 m (50,720 ft), set on 29 August 2006 by
Steve Fossett and
Einar Enevoldson, breaking the previous record by 1,713 ft (522 m). It was a standard DG-500M but the engine had been removed and replaced with liquid oxygen tanks. Additional instruments were installed powered by non-rechargeable batteries. The canopy had double-wall glazing and there was a drogue parachute for an emergency descent from high altitude. Pressure suits were worn. The glider is on display at the Seattle
Museum of Flight. A new altitude record of 52,172 ft (15,902 m) was set by the
Windward Performance Perlan II on September 3, 2017. ==Variants==
