An American Airlines plane with 64 people on board collided with an Army helicopter over Washington, D.C., and crashed into the Potomac River.

Authorities said the death is not related to the American Airlines and Black Hawk helicopter collision that happened on Wednesday night.

The bodies of 55 victims have been pulled from the Potomac River in Washington, D.C., following the midair collision between a commercial jet and a Black Hark helicopter on Jan. 29.
