Thanks for the lead in DJ, but I was sort of lost as to what I was supposed to be looking at, and couldn't translate the words scrolling by, but did find this one next to it, that was in English, and made a whole lot more sense as to what they were doing.....

Wow. astonishing buoancy control. the upside down stuff at the beginning looked almost impossible. I've seen people do the horizontal flying scenes before--just lots of weight and a steep cliff. Remarkable work though.
