Because gravity is an acceleration, not velocity, the longer you fall the faster you go.

only until you reach Terminal Velocity. (hey, that sounds like a great name for a film, doesn't it?)

PS, regarding gravity (which seems to be the main problem on this thread),

And of course certain basic principles apply, such as gravity -- thankfully!

who says middle-earth had the same gravity as our Earth? (yes, before you say it, I've heard it's meant to be Earth 10,000 years or so ago......) In a world where the elves only lived in starlight for a while, in a world where you can make someone invisible with a magic ring, in a world where some can have immortality, in a world that was once straight and now bent, in a world where you can get on a ship and travel away form the mortal coil, why can't we have Legolas shooting an arrow up at grima and hit him perfectly?

PPS re the beacons

those people live up there in the mountains where a blizzard can easily destroy those miserable huts?

This actually IS based on fact.
