Video shows helicopter crash in the Hudson River in New York City

A helicopter broke apart in midair and crashed upside-down into the Hudson River between Manhattan and the New Jersey waterfront Thursday, killing six people in the latest high-profile aviation disaster in the U.S., according to witnesses and a law enforcement official.

The New York Fire Department said it received a report of the crash at 3:17 p.m. All six people aboard were killed, a law enforcement official told The Associated Press. The official was not authorized to speak publicly and did so on condition of anonymity.

Witness Bruce Wall said he saw the helicopter “falling apart” in midair, with the tail and propeller coming off. The propeller was still spinning without the aircraft as it fell, he said.

Video posted to social media showed parts of the chopper splashing into the water, and the overturned aircraft was submerged, with rescue boats circling it.

The skies were overcast at the time, but visibility over the river was not substantially impaired. Rescue crews had to deal with 45-degree water temperatures.

The Federal Aviation Administration identified the helicopter as a Bell 206. The FAA and the National Transportation Safety Board planned to investigate.
