Bill Bennett founded Delta Wing Kites and Gliders in 1969 to build and market boat-towed kites, such as the Delta Wing Model 162 (see NASM collection), flown by water skiers. Bennett fitted these gliders with flexible wings evaluated at NASA by Francis M. Rogallo. Hang gliders equipped with Rogallo wings spread around the world because they flew reasonably well, cost little to build, and were easy to transport. By the late 1970s, Bennett had started to modify the early Rogallo wing designs to improve safety and performance. Skilled pilots flying these new gliders, including the Phoenix and Mariah series (see NASM collection), could perform loops and wingovers.
