Woman's Threats Force Diversion of Alaska Airlines Flight to Kansas City.

An Alaska Airlines flight from San Francisco to Chicago was diverted to Kansas City after a passenger, Chloe M. DaSilva, threatened to kill a flight attendant and acted erratically. She was arrested on a federal charge of interfering with the flight crew. The incident has raised concerns about the safety of crew members and is among many involving unruly passengers on flights. The Transportation Security Administration has resumed offering self-defense classes to flight attendants and pilots.
