Paper Airplanes

As a part of my goal to learn more about aviation, I looked up a few paper airplane designs and folded the good-looking ones myself. The one in the middle is the easiest to fold, looks the coolest, but doesn't fly too far (best used to impress kids). The one on the right has 2 collapse folds, doesn't look too cool, but flies the farthest (best used for competitions). The one on the left is in between.
I'll try to fold an F-15 fighter jet next time.
