UPDATE 2:41 p.m. Aug. 11: FBI and airline officials said investigators are still attempting to reach the crash site, located in dense brush on Ketron Island.
Jay Tabb, lead investigator with the FBI, said investigators have not been able to verify whether the man in the cockpit was the only person on the plane.
The man, who has not been identified, was employed by Horizon Air for three and a half years. He was credentialed to be around air crafts and passed criminal background checks, Horizon Air officials said.
Alaska Airlines CEO and chairman Brad Tilden said they believe the man worked his shift at the airport that night and was in uniform when he stole the plane.
The man was part of the airline grounds crew and his duties included loading and unloading luggage, along with cleaning airplanes between flights.
He also towed planes across the runway, Tilden said.
He performed complicated maneuvers to get the plane in the air, officials said.
He used a push back trailer to rotate the plane 180 degrees to position it on the runway.
Tabb said the man was not known to have a pilot’s license and wouldn’t speculate on how he learned some of the “incredible maneuvers” performed before the crash.
During the man’s “unauthorized” flight, two military jets in Portland were positioned to respond, Tabb said.
No ground structures were damaged.
Tilden said that about 75 flights were delayed Friday evening while the plane was in the air.
Sea-Tac International Airport resumed full operations by 1 a.m. Saturday morning.
Tilden said the company is “deeply saddened” by the situation and offered “sincere sympathy to family, loved ones and coworkers.”
UPDATE 11:50 a.m. Aug. 11: In a press conference Saturday, NTSB investigators said they would be searching Ketron Island for the plane's black box and cockpit data recorders, which will be transported to Washington, D.C. for further examination.
The plane is fragmented and the wings have been ripped off the plane, NTSB officials said. The aircraft also has significant fire damage from when it crashed overnight.
Investigators will be conducting interviews and continuing their search in daylight hours.
UPDATE: 5:11 a.m. EDT Aug. 11: The mechanic who took the plane was described by co-workers as "super normal." He was tasked with moving planes from the cargo area to the flight line between commercial flights. Meanwhile, the FBI office in Seattle has taken over the case. Officials said there are no new updates.
UPDATE: 3:04 a.m. EDT Aug. 11: Washington Gov. Jay Inslee tweeted that there were "still a lot of unknowns" about the crash. Inslee also thanked the Air National Guard units from Washington and Oregon for their efforts. "Those pilots are trained for moments like tonight and showed they are ready and capable."
UPDATE: 2:13 a.m. EDT Aug. 11: In a YouTube video released early Saturday, Horizon Air Chief Operating Officer Constance von Muehlen said she believed the plane was taken by a Horizon employee. "Our hearts are with the family of the individual aboard as well as all our Horizon Air and Alaska Air employees," she said.
UPDATE: 2:01 a.m. EDT Aug. 11: According to the Pierce County Sheriff's Office, the F-15s that were sent to follow the unauthorized plane were scrambled out of Portland, Oregon. The spokesman also said a sonic boom was caused by an Air Force plane and was not an explosion, as originally believed.
UPDATE: 1:19 a.m. EDT Aug. 11: The Pierce County Sheriff's Office said they were told that F-15s made it within a few minutes of the plane's unauthorized takeoff. Pilots kept the plane out of harm's way, the spokesman said.
UPDATE: 1:10 a.m. EDT Aug. 11: The Pierce County Sheriff's Office confirmed that the unauthorized pilot was a 29-year-old man from Pierce County who was acting alone. A spokesman described the man as "a suicidal male" and they know his identity. The spokesman added that it was not a terrorist incident.
