How to make Paper Airplanes instructions is a free application that illustrates how to make Paper Planes. Some are easy to bulid, some not, but all are fun to fold and fly.
You can experiment with aerodynamics on a smaller scale with nothing more than a single piece of paper. While it is possible to make more complex paper airplanes such as the flapping paper airplane or the delta wing paper airplane, these instructions will describe a fine flying plane requiring just moderate skills.
