Been a lifelong skydiver, but never anything like that! A 13000 foot sky dive will produce maybe 63secs of flying which is what the thing is all about. Can't help but wonder what a long cliff face dive like that would be like!? When jumping from a plane there is nothing to judge your decent rate unless you have another diver. Flying along those cliff faces @ 125 plus mph has to be awesome! The time under canapy is just getting down so you can repack and go again. Thanks for posting! Makes the adrenaline kick in just watching! A/Ho Indian Joe
