Hank: I (and I assumed 'cstorms' as well) meant the flips the one guy does during mid flight, not at launch or whatever you guys call it.
But thanks for that comment, that is fascinating and makes good sense but if you weren't a base jumper I don't think that it would ever come to mind that the opening gainers are part of the orientation involved in the first few seconds.
Cool stuff !
I saw one vid were Dean Potter was talking and he said that he know can track as good with no suit as he could with one two years ago.
It must be a hard skill to develop. Are those indoor flight centers of any use for training, or simply novelty ?
