If you drop an ant or a pea sized model car off a building it won't even suffer any damage hitting the ground, if you throw an elephant or a full sized train off a building, it will be pancaked or explode into pieces.
The strength of a bone increases with its circumference, but its mass increases with its volume. The volume increases incur expenses in inertia far more quickly than circumference incurs gains in strength.

Here's their synopsis: There are so many ways to fall—in love, asleep, even flat on your face. This hour, Radiolab dives into stories of great falls.
We jump into a black hole, take a trip over Niagara Falls, upend some myths about falling cats, and plunge into our favorite songs about falling.
Such a great episode, and great show - I recommend both to everyone.
