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، ABC News reported.

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 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."
