We've had very little snowfall in the area lately -- skiing surfaces are quite firm. Plus, as admirable as those teenaged heroes were, they were holding that section of orange fence with very little tension, I doubt that it did much to break the kid's fall. The fact that the kid escaped any injury is probably due to a) the fall height was pretty low (3 body lengths), b) the yellow crash pad cushioned the fall JUST enough, and c) 8-year-old bodies are pretty resilient (soft bones, low mass).
As for liftees, frickin' useless. Nothing new though ... par for the course. Luckily there was the instructor (blue jacket with faint white spot, i.e. nametag, on right breast) to place the yellow crash pad.
