Sure looks like a simulated engine failure for training or demonstration purposes to me. Why did he casually say "mayday" and not tell anyone what was happening and where they were going down? If they were really an emergency, you'd have a long hike out of the mountains after that. On top of that, I believe autorotations are a myth that helicopter pilots are told so they don't scream all the way to their inevitable demise. LolDam that dude was cool as a cucumber, and the passenger didnt even get one single "bitch be cool". You would think this was a normal and regular occurence, unbelievable.
