control stick in front of the pilot that descended from the wing above. Another version translated the same weight-shift control via cables. As the Paresev was towed in a kite mode, it usually rose from the ground at about and had a maximum air speed of about . The Paresev control pendulum weight-shift control system was presaged by a published patent, an early use of the hung pilot behind a cable-stayed triangle control bar in 1908 in the territory of Breslau, and then also by the "control wing" of George Spratt in the 1920s. Variants Paresev 1 - first flight on January 25, 1962, crashed on March 14, 1962. Frame fitted with a linen membrane wing and the control stick coming from overhead in front of the pilot's seat. Paresev 1A - first flight May 18, 1962, last flight was on June 28, 1962. Used a rebuilt frame from the Paresev 1, but had a control stick and a Dacron membrane wing. Paresev 1B - first flight on July 27, 1962. Last flight on Feb 20, 1963. Paresev 1C - first flight March 4, 1963. Last flight on April 14, 1964. It had a modified frame with a half-scale version of an inflatable parawing. Paresev flight log (NOTE – This log is incomplete*): Paresev Flight Log * The Paresev vehicle was flown 341 times. Thompson made numerous ground-tow flights and claimed about 60 air-tow flights. Peterson claimed 228 flights (ground and air tows). Grissom made two flights. Champine made four flights. Kleuver made at least eight flights. It is unknown how many times Armstrong, Hetzel, and Slayton flew. Operational history The Paresev completed nearly 350 flights during a research program that ran from 1962 until 1964. Using the fully flexible parawing or the tube-stiffened paraglider of the Paresev 1A, 1B, 1C as an alternate to spacecraft recovery was deemed too unreliable upon unfolding so round parachutes for water landings were used instead. The Paresev and other flexible-wing projects such as the Ryan XV-8 stopped being funded by NASA on 1965. Although Rogallo wrote about, modeled, and spoke about recreational applications including hang gliding, NASA was not in the business of applying Rogallo's family of airfoils to personal aircraft such as kites, hang gliders, and powered light aircraft. The Paresev was transferred to the Smithsonian National Air and Space Museum located in Washington, D.C. for display. Test pilots Milton Orville Thompson,
