inkling, I saw another one like this when I was trying to get the scoop on the killathrill one. One thing that makes the first one impressive if it's a fake is the scale; if you get an RC plane that large in the frame, then you are on such a long lens that you could never keep the plane in frame as well as it is in that video, your movements and the plane's movement would be wildly exaggerated. Of course if you're doing the fake on a professional scale, you can overcome all that.
No problem on the snark, I got overconfident on this one myself. I'm still not convinced one way or the other, totally. But there doesn't seem to be much background on that "pilot", or the clothing company, for that matter.
