Ten Original Paper Airplane Designs that fly well.

How to read these folding diagrams: As you are folding each model plane according to the instructions, remember that a simple dashed line is a "valley fold" (the paper goes down where that line is, and up on both sides of that line) and a dashed-and-dotted line is a "mountain fold" (the paper goes up along that line). For a paperfolding tutorial see The eight fold way or Wikipedia.

Teachers or students, may wish to look at NASA's Aerospace Activities and Lessons page. Also, for safety, you may wish to blunt the nose of some of these paper airplanes slightly so that they can't possibly hurt anyone.
