and for safe landing. Publicity from the Fleep and the Paresev tests sparked interest in the design among several tinkerers, including Barry Palmer, and Sport Aviation of 1962 shown Jim Hobson of Experimental Aircraft Association (wing shown on US national TV in Lawrence Welk Show in 1962). An Australian engineer Mike Burns developed and used the boat-towed Rogallo-airfoiled SkiPlane starting in 1962 through the 1960s. A fellow countryman of Mike Burns, John W. Dickenson, made ski-kites and eventually partnered with Mike Burns to improve the ski-kite; he formatted a ski-kite that used what could be found in the 1929 George A. Spratt simple triangle control bar or A-frame with single-point pendulum weight-shift control. An influence through John Dickenson's duplication of his device, who named his flexible-wing ski-kite the Ski Wing. Dickenson fashioned a water ski kite airframe to fit on a Rogallo airfoil where the pilot sat on a swinging seat while the control frame and wire bracing distributed the load to the wing as well as gave a frame freedom to be pushed/pulled for weight-shift control. Dickenson's Ski Wing turned out to be stable and controllable under tow, unlike the flat manned kites used at water ski shows. The Ski Wing kite was first kited in public at the Grafton Jacaranda Festival in September 1963 by Rod Fuller while towed behind a motorboat. Australian manufacturers like Bill Bennett and Bill Moyes, actively developed and marketed Dickenson's innovations to the world, which significantly fueled the hang glider revolution. Although by the early 1970s many rigid wings were developed, none sold well, while dozens of flexible-wing hang glider companies were springing up worldwide, building variants of Dickenson's Ski Wing. In 1972, Popular Mechanics and Popular Science magazines published articles on hang gliding which further increased its popularity, as the Sky Raiders hang gliding movie released in 1975. Francis Rogallo, Barry Palmer, John Dickenson, and others never made any money out of their innovations. Profit to manufacturers of hang gliders and Rogallo-winged hang gliders came once organized and insured sporting events grew in popularity. Dickenson's adaptation and innovations eventually produced a foldable hang glider that dramatically reduced difficulty in control, storage, transport, assembly and repair. In addition, the flexible wing lends itself to design changes for possible improvements. The crucial developments put together by the Paresev engineers, Barry Palmer, John Dickenson, Bill Bennett, Bill Moyes, Richard Miller, and then hundreds of other
