ok yeah i rewatched it that scene is definitely bullshit, first of all, no free solo climber ever makes a fully dynamic leap when they're hundreds of feet above the deck, second, even if you were stupid enough to do that, and you landed it, but then started sliding down an incline like that, a little edge on the vertical surface at the bottom of the incline you're sliding down simply cannot be caught; it is physically impossible to stop yourself with only a few centimeters to put your fingertips on like that, the momentum of your whole body will just take the skin off them and keep going
