Just what were they thinking?

From CBSNews:

(AP) LOS ANGELES - Pilots on an Alaska Airlines flight from Mexico City to Los Angeles locked down the cockpit and alerted authorities Sunday when a flight crew grew alarmed at the behavior of three men who turned out to be conducting an elaborate orthodox Jewish prayer ritual, officials said.

The men, all Mexican nationals, began the ritual that involves tying leather straps and small wooden boxes to the body, and the crew of Flight 241 alerted the cockpit, airline spokeswoman Bobbie Egan said.

Unbelievable!
