Development
The White Dwarf was commissioned and funded by comedian Gallagher, whose interest in airships was sparked by a radio-controlled flying watermelon prop he used in his stage act.[1] It was constructed by Bill Watson, who was part of the team that built the Gossamer Albatross human-powered craft.[2]
Design
The dirigible features a teardrop-shaped lift bag. The aluminum fuselage is a truss design with a single pilot seat on top with a chain-driven pusher propeller, 64 inches in length, positioned in front of a rudder. It weighs 150 lb (68 kg).[1][3]
Operational history
The White Dwarf set several world records with pilot (and engine) Bryan Allen. It was flown a distance of 58.08 mi (93 km) in 8 hours and 50 minutes.[4]
