My guess would be that less, and probably a LOT less, than 500 people who were on this planet in late 1971 would have the specific technical information on the 727 that Cooper had. Cooper probably had extensive experience in wearing parachutes but little, if any, in jumping itself.

Musika Farnsworth also has the first of a series of articles on the Cooper hijacking in the May 2010 issue of The Parachutist Magazine. Perhaps you could contact Farnsworth through that magazine and either get a back copy or a referral to where a copy of the article can be found online. Robert Nicholson
