I was browsing the internet and came across this. I found it on collegehumor.com. Here is the link to the video, but be warned there may be some material on this site that could offend some people.

This is a video of someone hovering his plane at a Keg party over a pool. If you watch closely you can see them hand launch it over the pool.
