Video of the Paresev (Paraglider Research Vehicle).
The Paresev (Paraglider Research Vehicle) was an experimental NASA glider aircraft based upon the kite-parachute studies by NASA engineer Francis Rogallo. Between 1961 and 1965 the ability of the Rogallo wing (also called "Parawing") to descend a payload such as the Gemini space capsule safely from high altitude to ground was studied. The Paresev was a test vehicle used to learn how to control this parachute-wing for a safe landing at a normal airfield. Publicity on the Paresev and the Ryan XV-8 "Flying Jeep" aircraft inspired hobbyists to adapt Rogallo's flexible wing airfoil onto elementary hang gliders leading to the most successful hang glider configuration in history.
