[edit] Popularity

From article: "Only since the late 1990's have these aircraft become popular in the United States, mainly as a result of the relaxing of the FAA regulations regarding ultralight aircraft." I don't think that this is correct. What rules changes occured in the 1990s? These size craft have never, I think, been regulated - and, in fact, were invented in the U.S. in the 1970s.

A search of the Federal Aviation Regulations does not show any rules changes in the 1990s affecting ultralights. Rmhermen 18:10, 19 May 2006 (UTC)

[edit] Earliest American Trikes

"...in fact, were invented in the U.S. in the 1970s. Rmhermen"

Hello, I am very interested in the history of hang gliders, precursor of the trike, and I just expanded the trike History section. I traced the first trike back to 1967 by Barry Hill Palmer (see its references for fotos), who never developed it any further. Then there is this huge gap of time until the late 70's in Europe, when R. Magallon introduced and marketed his trike. I am very interested on having more information of the trike you mentioned was developed in the USA in the 70s. Thank you. BatteryIncluded 23:21, 24 July 2007 (UTC)

[edit] Lavezzari glider

Removed the content below from the Lavezzari image caption and pasted it here. The information is interesting, but long and is best explained in the main text and in the context of Rogallo's research. In all material studied, Rogallo never quoted or mentioned the Lavezzari glider; It would be interesting to find out if F. Rogallo knew of Lazezzari or seen this image when designing his flexible wing. "Francis's Rogallo's patented wing closed the drag-producing performance lowering big central air-gap between the two sails, and also showed that boned and non-boned versions of the true-double-lobed wing could be made a viable wing type for many types of aircraft."
