Bill Bennett, the hang gliding pioneer who founded Delta Wing Kites and Gliders in 1969, lost his leading designer, Richard Boone, in 1982. Bennett hired a new chief designer, Robert England, and immediately put him to work designing a new competition hang glider design to replace the aging Phoenix Viper. England borrowed heavily from the Ultralite Products Comet introduced two years earlier. The area covered by the lower wing fabric increased again over previous models, to more than 87 percent.
