A helicopter carrying four tourists crashed into the East River on Tuesday afternoon after taking off from a launch pad on the riverbank, killing one passenger and injuring the others. New York Police Department divers pulled the dead woman from about 50 feet (15 meters) of water about an hour after the Bell 206 helicopter went down around 3 p.m. All the passengers appeared to be British tourists, police said. Officers usually assigned to counterterrorism duties heard of the crash and arrived at the scene to find the chopper inverted in the murky water with just its skids showing on the surface. Firefighters also responded to the scene. The pilot, Paul Dudley, and three passengers were bobbing in the chilly water, and it looked as though a man was diving down and coming back up, possibly in an attempt to rescue the remaining passenger, witnesses said. Officers jumped in and pulled out two women and a man, police spokesman Paul Browne said. The women were in critical condition, and the man was stable. All were hospitalized. The pilot made his own way to the riverbank and remained at the scene.
