Ten Original Paper Airplane Designs that fly well. (bestpaperairplanes.com)

Cool topic but this page has so many annoying ads and feels so much like a spammy rip-off of a more reputable site that I wanted to click "flag".

And this:

>These airplanes designs as well as the text and illustrations of them here are original copyrighted work and may not be reproduced in any form (except by folding an airplane for your own use.) It is illegal to create or publish instructions for folding them whether you take the trouble to create your own duplicate illustrations, or not.

... sounds highly dubious to me?

Some of those look pretty similar to ones I recall making from this book as a child: http://www.amazon.com/Great-International-Paper-Airplane-Boo...
