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.
