Extreme wingsuit base jumping

This is so insane. A couple of daredevils have decided that traditional base jumping with a wingsuit is just too boring. So what do they do instead? Oh, they still base jump with the wingsuit, but they do it while they literally glide alongside the mountain!

Usually, base jumpers will want to get as far away from anything as possible to minimize risk of accidentally hitting something on the way down. These guys have no fear as they fly down to the bottom at speeds of over 100mph! CRAZY!

Somebody should build a wind tunnel to simulate this kind of free-fall flying sort of feeling.
