It is easy to make an origami airplane. But it is not so easy to explain how to make an origami airplane in English. Let’s try it.
Place a sheet of A4 paper on a flat surface.
Hold the paper in half lengthwise.
Then unfold it.
Fold the top right-hand corner down and toward the center line to form a triangle.
Do the same with the left-hand corner.
Fold each side over once again toward the center line enclosing the previous folds.
Fold the entire right side of the plane over the left side.
Now all the folds are on the inside.
Fold the top folded edge to the original center line.
This will create one of your wings.
Turn the plane over and do the same to create the second wing.
Finally, pick up the plane and unfold each of the wings 90 degrees.
Don’t throw it at people, though.
