Hard to get an accurate estimate of how far these snowboarders fell from this highly distorted fisheye footage but I’m thinking it was from a somewhat in the range of a humorous height given the reaction of those who didn’t fly off the cliff.
Someone in the comment section chimed in and identified it as 15 meter drop in Switzerland but it’s anyone’s guess. Thankfully the landing looked to be forgiving or this might not have been laughter inducing.
