Paper Pilot: The Paper Airplane Pilot's Manual

Just published last month, it won pride of place in the new (June 2007) Wired magazine's "Playlist" feature.

"This handsome book opens with 24 marvels of modern aeronautics, from the iconic Mk. I-XXI Spitfire to the sleek F-22 Raptor. Each airplane's profile is packed with stats about its top speed, diimensions, and cost. But the really sexy stuff comes in the second half: All two dozen planes are illustrated as paper models that can actually be assembled and flown. Break out the utility knife and model glue and get lost in the clouds."
