The wipeout looks pretty scary because they’re on a steep incline (can’t tell if it’s a black, double black, etc.). From what I can tell, it looks like the person who wiped out was pretty out of control when they did, because the person taking the video was able to stop pretty quickly. They seem to be okay by the end of the video because they’ve slowed down or stopped, and there’s someone to help them at the bottom. As a skier, this video seemed scary because the original fall resulted in an uncontrollable slide down the trail. The video didn’t feel particularly staged, and because it seemed so uncontrolled it’s not funny. Since we don’t actually see what happened at the beginning of the fall, it would be better to at least see if the person ended up okay.
