We also never see him even attempt to restart the engine - let alone glide to a reasonable area to land (at the altitude he was at, he had time to think before jumping as a last resort - he also crashed the plane near what appears to be a road, which would have been sufficient to land such a small aircraft).
Instead, he immediately opens the door and starts looking below himself... with his conveniently already strapped-on parachute... and his go-pro selfie-cam. Without even attempting to call mayday or restart, he jumps.
He jumps without even radioing his location on UNICOM or closest airfield freq - made evident by his repeated claims he has no phone service and therefore can't reach help (I suspect he was hoping this entire video would avoid notice of authorities). He had plenty of time to radio for help and attempt a restart at the altitude he was at.
Everything about this video screams fake crash.
I hate to second guess a pilot in a real situation, but nothing about this video makes me feel it was a real situation. Seems like this youtuber was trying to get some easy views and that sweet, sweet monetization. What a shame, really gives the aviation community a bad rep if there's folks out there like him.
