On March 11, 2000, about 1625 Pacific standard time, Alaska Airlines flight 444, a Boeing MD-83, N974AS, operated by Alaska Airlines, Inc., as a 14CFR121 scheduled passenger flight, made an emergency landing at Seattle-Tacoma International Airport after a crew member found a suspicious device located in a passenger's backpack. Two flight crewmembers, three flight attendants. and 86 passengers were not injured; however, two passengers sustained minor injuries during the emergency evacuation. Visual meteorological conditions prevailed and an instrument flight plan had been filed for the flight.
