A pilot died after a single-engine plane crashed into a large field in Marysville Wednesday evening. 

The pilot, identified as 64-year-old Gregory Capes, was the only person on board, according to Marysville police. 

The Murphy Moose, a lightweight kit plane, crashed in the 15700 block of 51st Ave. NE. 

The National Transportation Safety Board is investigating. They said the plane was an “experimental amateur-built aircraft.”

It's unclear who the plane was registered to or the flight path of the aircraft. 

Witnesses in the area saw a plume of smoke and heavy emergency response, saying the crash happened near the Arlington Municipal Airport.
