SEATTLE- An airline mechanic stole an empty plane from Seattle-Tacoma international airport and crashed it near Ketron Island in the Puget Sound about 25 miles south-west of the airport.
The pilot was described as a 29-year-old mechanic. Nothing else has been revealed about his identity. It is not clear if the man survived the crash.
The unauthorized take off late on Friday forced the airport to close.
Two F15 fighter jets were pursuing the plane when it crashed.
Air traffic controllers tried to talk to the man, encouraging him to make a landing but he kept on doing loops over water.
The person had crashed by “doing stunts in air or lack of flying skills”, the Pierce County Sheriff’s Department said on Twitter.
In a statement, the airport said: "An airline employee conducted an unauthorized takeoff without passengers at Sea-Tac; aircraft has crashed in south Puget Sound. Normal operations at Sea-Tac Airport have resumed."
