It happened around 5:30 p.m. on Friday.
89-year-old Stefan Cavallo of Manhattan took off from Maryland around 4 p.m.
He started to experience engine trouble, which started to spray oil on his windshield.
The FAA tried to get Cavallo to land at MacArthur Airport, but he was descending too fast, so he was forced to make an emergency landing at Robert Moses State Park.
Cavallo managed to land the cessna in the sand, and just narrowly missed crashing into a boardwalk at the park.
Amazingly, the pilot, who was the only person inside the plane, experienced just cuts on his head and neck and is expected to be fine.
Cavallo was a test pilot in World War II, and has plenty of experience flying.
