First manned box kite flightIn 1894, Lawrence Hargrave, the Australian inventor of the box kite, linked four huge box kites together, added a sling seat, and flew - attached to the ground by piano wire. Due to their innate abilities to carry heavy payloads, steady flight, and capacity for high altitude flight these kites have had many industrial and military uses in the past. Box kites were used until the 1930's to carry meteorological equipment for high altitude weather studies and by the Royal Air Force as sea rescue equipment to deliver radio aerials. Hargrave also made important studies of wing surfaces and worked with rotary engines and gliders. |
