I still laugh at the "What Is Love Dubstep" version of the video. My understanding is that none of the injuries were serious. You don't see remixes of the double fatal cat blowover from a few years ago. And, yes, the GoPro should have gone swimming!
If you a talking about the Fountain Spin Out video. EVERYONE on board was injured and some were serious and still not back to pre accident condition. The one person on board was a camera man for the local TV Station and that is part of the reason it hit the air so quickly.
The owner is a nice person. He had purchased the boat and it was set up from the previous owner to run shoot out for speed. To put it mildly it was not set up for normal running. Unfortunately his driving has been criticized by every keyboard cowboy in the world by now. I am sure he just wished it would go away...
