>The one that always makes me wonder is when the airline says "We're staring preboarding" and then people get on the plane. Ummm.. no... preboarding is when you're sitting at the gate waiting for them to open the door. Once people start getting on, it's boarding.

And whenever I heard "door" connected with the verb "board", it was about an abandoned or condemned house, where all the windows and doors were boarded. I wonder why would they do that to an airplane ;).
