plane has crashed in Washington state after a mechanic stole it from the Seattle-Tacoma International Airport, the Pierce County Sheriff's office said.

皮尔斯郡警长办公室近日表示，一名机械工从西雅图-塔科马国际机场偷走了一架飞机，后于华盛顿州坠毁。

The aircraft took off without authorization¹ and without passengers with "an airline employee" at the controls, airport officials tweeted last Friday.

机场官员上周五发推特说，这架飞机未经授权起飞，机上没有乘客，飞机仅由“一名航空公司员工”控制。

The plane went down on Ketron Island, which is about 40 miles southwest of the airport, the sheriff's office said.

警长办公室称，最终这架飞机在距离机场西南约40英里的科特罗岛上坠毁。

The mechanic has only been identified as a 29-year-old man from Pierce County, sheriff's spokesman Ed Troyer tweeted.

警长发言人埃德·特罗耶尔发推称，目前仅能确认该机械工为皮尔斯郡的一名29岁男子。

"It is believed the mechanic's lack of flying skills led to the crash," Troyer said.

特罗耶尔表示：“据称该机械工缺乏飞行技能，因此导致了坠机事故。”
