A New York City sightseeing helicopter on a maintenance flight made an emergency landing on Tuesday at a New Jersey cargo port after the pilot reported possible engine trouble.

Two people were aboard the Bell 206L-4 helicopter when it came down on a road at the Port Jersey Marine Terminal in Bayonne, across the Hudson River from Manhattan, around 8:55 a.m., the Federal Aviation Administration said.

No injuries were reported, the Port Authority of New York and New Jersey said.
