A small plane collided with a sightseeing helicopter carrying five Italian tourists over the Hudson River on Saturday, scattering debris in the water and forcing people on the New Jersey waterfront to scamper for cover. Authorities believe all nine people aboard both aircraft were killed.
Another helicopter pilot on the ground at the heliport for Liberty Tours, which operated the doomed sightseeing craft, saw the plane approaching the helicopter and tried to radio an alert to the pilots, police Commissioner Raymond Kelly said. The warning wasn't heard or didn't happen in time.
The collision, which Mayor Michael Bloomberg said was "not survivable," happened just after noon and was seen by thousands of people enjoying a crystal-clear summer day from the New York and New Jersey sides of the river.
