	Hang Gliding in the Aviation History Encyclopedia
		Hang gliding was invented, or at least strongly influenced, by the NASA technician Francis Rogallo in the 1960s who had to develop a landing system for the Apollo astronauts return to earth.
		Many early experiments with gliding flight throughout the late 19th century were performed using craft that would now be considered hang gliders, and interest in the sport continued throughout the 20th century.

		Rogallo’s pioneering Flexikite, made during the course of his long career as a government research scientist, was sewn by his wife Gertrude from a flowered chintz curtain, and can still be viewed at the couple’s airy home near Kitty Hawk, North Carolina.
		Rogallo shared 1992 honors with the Magellan Project Team of California’s Jet Propulsion Laboratory for its successful radar mapping of the cloud-shrouded planet Venus via spacecraft.
		Rogallo also developed a maneuverable parachute and a sophisticated parawing to accurately control the landing of returning spacecraft.

		Francis Melvin Rogallo earned one of the first Aeronautical Engineering degrees issued by a United States educational system, from Stanford University, in 1935.
		Francis Rogallo believed that flexible wings provided more stability than fixed surfaces.
		Rogallo�s early kites needed up to twenty-eight shroud lines, although their tendency to tangle convinced him of the need to design simpler models using six, and then finally four lines.

		On March 20, 1951, Francis and Gertrude were granted a patent on the design of the Rogallo wing.
		Rogallo conceived the thought of making an aircraft wing as a parachute-like flexible structure that would open and maintain its shape by wind pressure.
		With his wife Gertrude's help, he made small models that were tested in a wind tunnel at their home.

		In Hampton, Virginia, Francis Melvin Rogallo, who had earned one of the first aeronautical engineering degrees issued by a U.S. educational institution (Stanford 1935), was serving in the mid-1940's as a researcher and wind tunnel manager at the facilities of Langley NACA (National Advisory Committee on Aeronautics)-which later became NASA (National Aeronautics and Space Administration).
		Francis, in a magnanimous action which reflects his love for his wife, designated that the patent be in Gertrude's name.

	Rogallo wing
		Steerable rogallo kites usually have a pair of bridles setting a fixed pitch, and use two strings, one on each side of the kite, to change the roll.
		Most man-rated rogallo wings change the pitch and roll by suspending the payload or engine on a pendulum beneath the wing, and then moving the pendulum to change the vehicle's center of gravity.
		Further, if constructed from heat-resistant materials with an appropriate engine, it can form the wing of a supersonic waverider.

		In 1964 a Brisbane newspaper had published a picture of John Dickenson's creation and a man called Robin Bishop had seen it and wrote to his friend Francis Rogallo in Virginia, USA, explaining that an Australian had independently developed the Rogallo principle into a perfectly viable man-carrying airplane for so little money it was laughable.
		In Francis Rogallo's reply to John dated 29th January 1965, he says, and I quote directly: "To get back to your glider design, I hope to make some copies of your drawings and perhaps have some individual or groups build a glider like yours locally...

		The major impetus for this rebirth was the adaptation to hang gliding of a new type of wing, invented by an American engineer named Francis Rogallo.
		Rogallo had originally invented the wing with the idea to create an aircraft which would be simple enough and inexpensive enough that anyone could have one.
		The Rogallo wing was an extremely simple wing, consisting essentially of two sails joined along a central spar, forming a delta shaped single surface fabric wing.

		Prior to the Rogallo invention, the only wings in existence were rigid—used for kites, gliders, and airplanes—which meant they were heavy, expensive, and impractical for recreational flight.
		Using the Rogallo wing, Du Pont and other companies began manufacturing stunt kites, which were sold to children rolled in tubes.
		Soon more toys and recreational aircraft were born from the Rogallo creation.

	Rogallo wing - Wikipedia, the free encyclopedia
		The Rogallo wing (invented by and named for Francis Rogallo) is a simple, inexpensive flying wing with remarkable properties.
		Most man-rated rogallo wings change the pitch and roll by suspending the payload or engine on a pendulum beneath the wing, and then moving the pendulum to change the vehicle's center of gravity.
		A rogallo wing is two partial conic surfaces, sharing one side, with both cones pointing forward.

		The unpowered Paresev was based on the design of the Rogallo wing, conceived in the late 1940s by Francis Rogallo, an aeronautical engineer who worked at the Langley Research Center for the NACA (National Advisory Committee for Aeronautics, the predecessor agency of NASA).
		Rogallo wings and variations on the original design are now being flown by hundreds of thousands of hang glider enthusiasts around the world.
		The parawing concept was not selected for the spaceflight program, but interest it generated because of the NASA study helped popularize the Rogallo wing which made the sport of hang gliding one of the most widespread forms of flying throughout the world.
