Not quite a paper airplane

I know that this is the place for how to make paper
airplanes yet if you are interested in planes at all
you may enjoy this video clip. My daughter is
attending a magnet school where she is in the
engineering magnet program. This video was
forwarded by the head of the engineering department.

The video is of a model B-29 which is powered by 4
chainsaw engines. While you watch the video keep an
eye out for the Bell X-1 launch from the B-29.

Enjoy the flight.
