Once you've folded and fine-tuned a plane, the first thing you'll want to do is send it soaring. A good flight requires a good throw, and a world record throw requires practice. The type of throw you use depends on the kind of flying you want to do and, to a lesser degree, on what plane you are using.
All throws require a comfortable, secure grip on the plane, normally using the thumb and forefinger.
Hold the plane on the bottom, near the front. The launching technique for slow flight begins with the paper airplane in front of the shoulder. Throw gently but firmly. Throw the plane gently and level for shorter distance, faster and a little upward for longer ones. Obviously, the World Record Paper Airplane is well suited for a hard throw, but many other square designs can be thrown this way as well.
