This has to be one of the most amazing stunts I've ever seen - sky diving down the side of a mountain. I would not be entirely shocked if it was shown to be fake, it is that impressive.

The video was made in 2003, so perhaps it has been shared in this forum before. I did a search, and didn't find it, though. If it's old stuff, this thread can be deleted.
