The paper planes you used to fold as a kid flew well, but they probably looked nothing like the slick aircraft used by air forces around the world. So the folks at Featuring-Featuring, a London-based design studio, created a book full of paper aeroplanes that are far more recognisable.
You probably don't need to be an origami master to realise these creations, but a basic understanding of folding on the dotted line is needed to properly assemble the paper F-117 Nighthawk, Harrier Jump Jet, Predator Drone, and Sukhoi SU-27.
The $US7+ ($10) Paper Plane book includes multiple versions of each model printed on paper with varying wild patterns, and about $US1.50 ($2) from each one gets donated to UNICEF if you need another good reason to buy one for yourself. [Featuring-Featuring via Notcot]
