- Definitely merge "Parawing" into "Rogallo wing" with a redirect, there is not enough material in the former article to justify leaving it separate. I will merge it if no-one objects within a week or so. User:Jaganath 13:30, 29 August 2006 (UTC)
Care should be made to clear the hyperbole regarding the Dickenson story.
I thought I would switch the order of inventors since Gertrude is listed as first inventor on two of the early patents. This doesn't mean that she was the "primary inventor", but I suspect that her contribution was substantial given the rarity of women inventors in the US in the late 1940's.--Nowa 12:14, 22 August 2007 (UTC)
Invention vs. Development
Moved this discussion from the main article body into this discussion tab:
"There are two sorts of invention, one is ornamental appearance invention that may or may not function. Then there are process patents that speak to invention of process and function. The Dickenson ornamental appearance for a Rogallo kite and hang glider was new, but he did not invent the function, the machine, the process; those were extant before him in aviation and in hang gliding; reference the fact that Barry Palmer in 1960-61 rejected the ski-kite trapeze but still put the trapeze at his back while he used struts to it to explore centers of lift by having his body move in front of the triangle while on triangle bars; reference his primary data voiced video and e-mail testimony to primary reseacher John Bentley. Dickenson had ornamental invention, not process invention on the seat and ski-kite trapeze."

- Actually, Dickenson did not even have much ornamental invention, if at all. Clearly the Breslau 1908 battened flexible wing hang glider had the cable-stayed triangle control frame at a hang glider meet. And in 1962 James Hobson had a "Rogallo Hang Glider" with triangle control frame. And earlier at the start of the 1960s before Palmer and Purcell who had the triangle control frame in hang glider, was John Worth of NASA who at many scales and craft showed the triangle control frame beneath the four-boom Rogallo airfoil. Hung seats from hang glider were "obvious" in hang gliding from 1800s and taught by Chanute and others. When obvious is the character of a slight ornamental, then such is not an invention step. So, no ornamental invention for Dickenson; such would also invalidate Bennett's later ornamental patent. 220.127.116.11 (talk) 19:06, 27 September 2013 (UTC)
Graeme Henderson keeps throwing legal threats, insults and vandalizing this article and any other related to hang gliding in part due to the terminology established decades ago, that is the Rogallo Wing airfoil adapted for use in hang gliders by John Dickenson. History is not selective; the airfoil invention by Rogallo is mentioned as well as its application on hang gliders by Dickenson. His intolerance to factual history, which is extremely well documented on NASA and Smithsonian Air & Space Institute web sites among others, is a childish act he has kept for over one year now.
