Investigation Launched Into 'Suicidal' Man Who Stole and Crashed Plane

(OLYMPIA, Wash.) — Investigators worked to find out how a "suicidal" airline employee stole an empty Horizon Air turboprop plane, took off from Sea-Tac International Airport and crashed into a small island in the Puget Sound after being chased by military jets that were quickly scrambled to intercept the aircraft.

The bizarre incident points to one of the biggest potential perils for commercial air travel — airline or airport employees causing mayhem.
