This plan is known as one of the best paper airplane ever! It is also very simple and easy to make.
First, take out a new paper ( A4 is the best choice)
Fold the paper in half to make the lengths perpendicular, then unfold it.
Fold the 2 corners into the middle of the sheet to make the it looks like an arrow.
Fold the head of the paper ( which looks like an arrow ) down.
Fold 2 corners of the paper down to make the sheet looks like an arrow again ( just like what we did in step 3 )
Fold the small triangle ( which looks like a flap and it is at the end of 2 right angels ) up
Just fold the paper in half so that 2 wings are perpendicular
The last step: Fold the top parts of 2 wings down, and now we've done. Launch it and you will feel satisfied !
