A family of four escaped serious injury Friday afternoon when their plane crash-landed in a Sussex County lake.

Andover police say that the Cessna airplane was en route from Harrisburg to Morristown Airport, but was diverted to Aeroflex Airport in Andover due to flight restrictions stemming from President Donald Trump's visit to his Bedminster golf resort.

Police say that the pilot overshot the runway and landed in the water. Two adults and two children were aboard the plane, and they were rescued by a nearby fisherman who drove his boat to the crash scene.

The family members sustained minor injuries.

The Federal Aviation Administration is investigating.

The Associated Press wire services contributed to this report.
