From wikipedia:
On October 22, 1986, at 4:44 PM, while Dornacker was giving one of the station's N-Copter traffic reports, the helicopter plunged from an altitude of roughly 75 feet into the Hudson River. On her final radio broadcast she was giving a report of a tractor trailer and a car getting into an accident and a car fire. She also stated that the outbound Holland Tunnel was heavy with traffic and that the Lincoln Tunnel was much better with traffic and a car fire. Dornacker was starting her report for incoming New Jersey traffic when the helicopter stalled in mid broadcast.
Jane Dornacker was the traffic reporter who died in that crash.
