The best (as in most dramatic) high fall death I've ever seen was performed by Dar Robinson in the Burt Reynolds film Stick
. He appears throughout the film as a bad guy, and it's even more shocking when you him fall from a railing screaming, firing all his bullets at Burt, and there's obviously no airbag under him. No blue screen either.
Here's the scene. May be NSFW due to language.
