POTOSI, Mo. (AP) — The Missouri State Highway Patrol says a Missouri man died when his ultralight plane crash in northeast Missouri.

The patrol says the plane belonging to 68-year-old Dean Wagner of Belgrade, Missouri, went down Monday evening in a field near Potosi in Washington County.

Sgt. Al Nothum says witnesses told authorities Wagner was doing stunts with his one-seater, single-engine aircraft when one of the wings malfunctioned and the plane went down.
