Here's a little secret: The airport news service filters the news. You will never see a newsworthy air disaster on an airport screen, even if such a report is being carried by CNN. The airport operation runs on a 10-second delay, which allows it to edit on the fly, pun intended, to block "bad" airline news from passengers who might be upset by it. The network usually covers banned news by throwing in a quick weather report or other filler.
