NBC EXCLUSIVE: Video of Hudson River mid-air collision

NEW YORK, NY (NBC) - Video of the mid-air collision between a small private plane and a tour helicopter over the Hudson River in New York has surfaced.

Viewers should take note that this video is disturbing to watch.

The footage was shot by an Italian tourist who was experimenting with his new camera while boating on the river.

He captured the collision shortly after zooming in on the tour helicopter as it was flying over the river, just as the small plane came into the frame from behind.

The plane appears to break apart on impact.

There were no survivors.

Nine people were killed, two on the plane and seven in the helicopter.

The National Transportation Safety Board will use the video to investigate the crash.
