I went to visit my grandfather this weekend in Kansas, and he told me a story of the time he was in the Air Force and he was sitting alone in a huge hangar housing a B-52. He was bored out of his mind so he picked up a drill and started messing around with it. Eventually he thought it would be interesting to poke at the tires of this giant aircraft with that drill. He drilled straight through the tire and deflated it. It took ten servicemen and $10,000 to replace it. So just remember, whenever you think you're bored, you'll never be bored enough to pop a $10,000 airplane tire with a power drill.
