The Best Paper Airplane on the Planet Included in the compact and cheekily funny package you'll find: simple step-by-step instructions for folding "the Nakamura Lock" (the absolute best design for paper airplanes), tips for fixing ornery flight patterns (like the "serious hook" and the dreaded "flip over and crater"), some basic physics explaining how planes fly (thrust, drag, gravity, and lift demystified!), and thirty-five aerodynamic, colorfully patterned sheets of 8½"x11" paper (with the crucial first fold already in place).
