OK just so you know this is not a paper airplane thats meant to fly, just to look cool.
There are 3 different kind of airplanes it will turn into and only take one or two steps to transform it.
1st picture- The original design
2nd Picture- The space shuttle
3rd picture- The double jet!
Step 1: Folding Triangles...
Cut an 8 by 11 sheet of paper in half and fold the ends down like in picture 2. Then fold it the other way (Picture 3). Now that you have an X shape on both ends, fold the outside parts of the X inwards so the top forms a triangle. (See next two pictures for what it should look like.) Apply to both sides. Now you should have a strip of paper with two triangle shapes on the end.
