A guy that has spent quite a bit of time studying flying animals has told me the video is "unconvincing" and his conclusion was that the takeoff and landing were faked. He does however believe that such a contraption is viable. It has all the classic symptoms of internet BS. emotional music, emotional reaction, more video footage of people walking around than the actual flight, no video of anything from start to finish, blurry, Go Pro shows helmet then it doesn't. Video sequences are just a few seconds in length. My conclusion is the guy started out with good intentions, realized it wasn't going to work so went with a fake to generate page views.
