Patrick Weir is one of the operators, wasn't me. We did sell these guys their S800, and keep in touch almost weekly with them. They sent us the clip of the waterfall quite a while back. Since then, they have been filming Aerial Non Stop. These guys fly their s800 all day almost every day. They have flown the Hell out of it in some of the harshest conditions, from the Jungles to the Alaskan glaciers. I think the work they do is pretty damn spectacular. I love watching the show, because its so clear to spot the S800 Shots. Freakin awesome. Here is one of their reels.
