Getting it up and keeping it up.

OK, I saw the video below and couldn't resist tossing in my two cents about it. I remember as a kid making paper airplanes. The best - best - ones would travel maybe 20 to 30 feet before touching down. Actually, most of them crashed more than touched. And that was after a loop resulting in a nose-crumpling imitation of an auger. 

Even when I cheated and used paperclips and tape, I doubt a Slang-designed airplane ever made it more than 50 feet.
