Speaking as a professional and FIS World Cup Masters racer, he’s a good skier, good, but not a very good ski racer and not at all ready for any kind of real speed. He just doesn’t have the skill set......hope he lives!
What I’m seeing in that clip is not the form of an expert or anything close. I would hesitate to take him out on any serious territory in the West. Perhaps since he is used to high speeds in one area of sport he was not appropriately intimidated when he tried skiing and overestimated his abilities. It happens. Sometimes fear is a good thing. I hope he pulls through.
