Sunday morning near midnight there was another terminal dump, this one at Anchorage. As one pilot said, lots of "airport drama".

"...No one was explaining what went wrong or how serious the breach was. In many American airports, a person walking the wrong way through a secured exit has been enough of a reason to evacuate an entire facility until the person could be found. Whether that was the case in Anchorage early Sunday could not be determined.

Typical was the case of passengers arriving on Alaska Airlines flight 143 from Portland. It landed early, a few minutes after midnight, but as the plane pulled toward the gate, it came up short. The pilot came on the intercom and told passengers that "some kind of airport drama" was underway and pointed to the flashing lights of police cars on the tarmac..."

Caused by a passenger making a reference to a bomb in a suitcase. Bad joke or idiot?

"...He said the incident began a little after midnight (1 a.m. PDT) when the man, who was traveling with two male companions, made a reference to a bomb in a bag that had been checked into luggage.
Travelers were evacuated to another terminal, while police and others search the luggage. Parrott said that so far, no explosive has turned up..."
