The First Hang Glider wing Designs! A great item for Nasa and Hang Glider enthusiasts
Between 1961 and 1965, the ability of the Rogallo Wing (also known as Parawing) to descend a payload such as the Gemini space capsule safely from high altitude was studied.
The Paresev was a test vehicle used to learn how to control this parachute wing for safe landing at a normal airfield.
The publicity inspired hobbyists to adapt the Parawing into the first Hang gliders
