HOLLAND TWP., Pa. -

A 71-year-old Hunterdon Co., N.J., man died when his small plane crashed near the Delaware River on Wednesday.

The pilot, Joseph Borin, of the Whitehouse Station section of Readington Township, was the only person aboard the plane when it went down around 5 p.m. in a remote area of Holland Township, off Route 627, county officials said.

Search and rescue units on both sides of the Delaware River searched for more than five hours in terrible weather conditions before the plane was found around 10:30 p.m., said Anthony Kearns, the Hunterdon County prosecutor.

"We believe Mr. Borin was attempting to reach Alexandria Airport in dense fog and rain," Kearns said.

The National Transportation Safety Board and the Federal Aviation Administration arrived on the scene Thursday to begin an investigation.

Anyone with information about the crash is asked to call the Hunterdon County prosecutor at 908-788-1129.
