I saw the tail end of a report on this yesterday at work (on Cnn cause I'm allowed that instead of Espn when I open the bar). So I had to look it up and honestly, this is awesome. I know its not exactly correct to think of a disabled person as "different" but gosh, think of being stuck in a wheelchair with a mind like his. And then think of how much being weightless would mean to you, even for just a minute or two.
