Ah, zooming back in on schedule is a fast airplane. What's kind of funny is that I used to fold a paper airplane shaped almost exactly like this back in grade school. The only difference is that I'd start with letter sized (8.5" x 11") sheet of paper. The extra folding at the front of the plane help move the center of gravity forwards, which is why it performs so well. (Can you tell I used to be into model airplanes as a kid?!)
