How to REALLY Screw up an Airport

Some guy in Newark messed things up for thousands of travelers:

A man walked through a screening checkpoint exit into the secure side of a terminal at one of the nation's busiest airports on Sunday night, and flights were grounded for hours and passengers had to be re-screened while air safety officials searched for him.

I have to fly out of the very busy Terminal 1 at LAX on Friday and I'm more afraid of something like this happening and screwing up my day than some terrorist getting on the plane
