An Alaska Airlines flight bound for San Francisco made an unscheduled landing on Oct. 22 after an off-duty Alaska Airlines pilot allegedly attempted to disrupt the operation of the plane’s engines, which was described by officials as a “credible security threat.”
The flight, which was operated by the carrier’s regional subsidiary Horizon Airlines, had departed from Everett, Washington, when its crew reported a “credible security threat related to an authorized occupant in the flight deck jump seat,” Alaska Airlines said.
