Evacuation Flub Spooks LAX Displays accidentally tell passengers to clear out By Matt Cantor, Newser User Posted Apr 23, 2013 6:20 AM CDT 3 comments Comments An American Airlines plane takes off at LAX International airport in Los Angeles Monday, April 22, 2013.

Turns out the message was an accident, airport authorities say. The message appeared at 9:47pm. "After the mistake was discovered, airport staff removed the message from all the monitors by 9:54pm," a spokeswoman tells the Los Angeles Times. At first, officials thought a hack was to blame, prompting a hurried investigation. But they ultimately realized that an airline contractor had accidentally overridden the flight display system, the spokeswoman says. The contractor was "programming airline check-in information into a set of monitors for a particular flight when he accidentally activated the pre-programmed emergency terminal evacuation message," she explains.
