Then there was the time they were flying through turbulence. Some of the passengers became alarmed at how much the wings were bending in the rough air and one of the flight attendants relayed that message to the captain.

His announcement:
Ladies and gentlemen, I've been informed that some of you have noticed our wings bending in the turbulence. In fact, the flight attendant told me that the wing tips are bending as much as ten feet in the bumps. Well, that's perfectly normal; there's nothing to worry about. Our wings are designed to bend as much as thirteen feet at the tips and, as you can see, we're nowhere near that yet.
