Realize the realizations that had to occur before that fact; trace the steps feeding that fact; walk backwards into people, flight models, patents.
Then in parallel find and detail all the works of John Worth related to four-boomed "Rogallo"-winged configurations that held triangle control frame where the weight positioning of payload was controlled for kiting, gliding, and powered flight. Notice that the full mechanicals were demonstrated by many, even in amateur sports. Yes, all before the end of 1962. Let such base inform one when facing untenable claims of "invention" coming out of a late-1963 ski-kiter and his later decade over-zealous fan. FAI an some orgs in our sport fell blind before the over-zealous single-man-in-mind fan; the result is an ongoing silly history of hang gliding in some quarters that ignores fact and the actual merits of many people. A huge preamble exists prior to E.A.A.'s 1962 publication about a built and operated "Rogallo-wing Hang Glider" for foot-launch use; yes, published in 1962. The late comers of late-months' 1963 were locally on time for themselves, but such local late play does not justify ignoring the works of prior others.
Even John Worth used hang glider technology that had been exhibited in 1908 by W. Simon of Breslau. The below-keel cable-stayed triangle control frame was demonstrated in a hang gliding organized sporting meet by W. Simon in 1908. Such mechanical was used again by John Worth; John worth even used a second such control-mass-of-payload-position cable-stayed triangle to stabilize payload in the positions wanted for flights.
The PARESEV was only one of several flows over the subject wing.
