Here's a case of air rage that took place even BEFORE the door closed. My CO flight between EWR-ATL was delayed a few minutes yesterday while the captain escorted a couple of foul-mouthed young passengers off the aircraft to the cheers of the front section of coach shortly after completion of the boarding process. The pilot apologized for the slight delay, explained that the individuals "really showed their true colors in the jetway", and got us to Hartsfield on time.
