GT,..........as Moe mentioned,...ya' gotta' have BIG cajones to pull off that type of flying. Or a bit whacky. Or both. I've seen other videos of these guys jumpin' off a Norwegian mountain cliff and then spread their wings like Batman. Over a year ago Morley Safer of Sixty Minutes did a segment piece on these guys. One of the star jumper-flyers mentioned about the friends he's lost through this type of activity to Safer. But he was still at it.
