It seems like every week there's a news story about an airliner being diverted. Or someone being booted off a flight, due to questionable passenger behavior.

This week's examples include a US Airways jet that was diverted to Bangor, Maine because a passenger claimed she had a surgically implanted device. She handed a flight attendant a note, written in French, seeking help and stated that she had an object in her body that was out of her control, according to reports.
