iPhone survives 1,000 foot drop from an Air Force plane

Okay, how impressive is it that U.S. Air Force Combat Controller Ron Walker's iPhone 4 survived a 1,000 foot drop from an airplane without a scratch on it?

The plane was traveling at 130 knots (roughly 150 mph) when he stuck his body out of the plane door to look for landmarks. At that point, one of his pockets opened and his iPhone took flight before plunging to the ground. “Well, guess I’ll be buying a new phone,” he thought to himself, and continued on with his duties.

He and a friend later used Find my iPhone and some ATVs to hunt down his iPhone 4. He did have a Griffin Motif TPU case and an aftermarket metal backing (so my worries about the glass back haven't been alleviated!), but that's still very impressive.

What's the worst fall your iPhone 4 has survived unscathed?
