I've never seen a human fall from a high place, but I always assumed they'd kind of "splat" on the ground. They always seem to in the movies, eh? Connecting with the earth sounds like a dull "thud." However, I just read an article from The Chosun that reads:
"A worker at the Lotte World amusement park in Jamsil, Seoul, plunged to his death while checking a ride on Monday afternoon. The worker fell to the ground from a rollercoaster car and bounced into the nearby lake. Rescuers who rushed to the scene were unable to save him. Police is investigating to determine the cause of the accident."
How rubbery could he be to bounce into a nearby lake? How close was the lake? Maybe there was a trampoline underneath the rollercoaster. Yes, that must be it.
