An empty Horizon Airlines plane has crashed after it was stolen by a ground employee from Seattle-Tacoma International Airport on Friday around 8 p.m., according to local authorities and a senior federal aviation source.
North American Aerospace Defense Command scrambled fighter jets to accompany the plane, which was steered away from Seattle and Tacoma by air traffic control, on its hour-long flight, according to the source. The Pierce County Sheriff’s Department said the two F-15s were not involved in the crash.
The crash happened on Ketron Island, which is southwest of Tacoma, in south Puget Sound. The small island has only about 20 year-round residents.
The employee who stole the plane was 29 years old, from Pierce County and called “suicidal” by the sheriff’s department. Horizon Air COO Constance von Muehlen confirmed the man was an employee of the company.

The sheriff said this was not a terrorist incident.
“Most terrorists don’t do loops over the water,” Sheriff Paul Pastor said. “This might have been a joyride gone terribly wrong.”
The Pierce County Sheriff’s Department has a number of vessels on scene, while the U.S. Coast Guard is on scene as well.
The Pierce County Sheriff tweeted, “Stolen horizon airplane crashed into Ketron island. Preliminary info is that a mechanic from unknown airlines stole plane. Was doing stunts in air or lack of flying skills caused crash into Island.”

The FBI said it was in contact with officials, but it was too early for them to comment on specifics.
“The FBI is communicating with local, state, and federal partners but it is too early for us to put out details on the rapidly evolving situation,” the FBI said in a statement. “We frequently get involved with matters related to aircraft so we are poised to act if information develops to suggest a federal criminal nexus.”
