At least 38 people have died in helicopter crashes in New York City since 1977, when an incident on a skyscraper landing pad led the city to start putting restrictions on where choppers could land. Helicopter flights are getting renewed scrutiny after a fatal crash into the Hudson River on Thursday.

A fatal crash Thursday became the latest incident in a long history of helicopter wrecks in the New York City area.

1986: An NBC radio traffic reporter dies when the helicopter she is riding in loses lift, hits a fence and crashes into the Hudson. 1985: A passenger drowns when a sightseeing flight operated by New York Helicopters crashes into the East River after taking off from the East 34th Street heliport.
