Wingsuit flying. Wow!

Have you heard of wingsuits? I hadn't.
Click once on videos to play here, and double click to open in a new window (this gives you the option of viewing them full-screen).
Most of these videos are of base jumping, and one is of aeroplane jumps.






I discovered wingsuits from Shankyrich's journal on h2g2. You'll find there a link to yet another wingsuit video.
It's fantastic stuff.
