The FAA and NTSB have launched an investigation into how an American Airlines flight collided with a military helicopter over the Potomac River.

More information about the passenger jet collision with the Army helicopter has come into the newsroom.

The American Airlines jet was carrying 60 passengers and four crew members when it collided with Black Hawk Army helicopter built by Connecticut's Sikorsky.

Defense Secretary Pete Hegseth calls the deadly aircraft collision involving a Black Hawk and a civilian airliner "a tragedy" in a statement obtained exclusively by Fox News.

A Black Hawk helicopter can transport up to "12 fully equipped, seated troops in combat," according to Lockheed Martin, the weapons company that builds the helicopter. There are about 5,000 of these helicopters in use by the United States Military.

Military spokesman Ron McLendon II said the Army is joining an investigation into the crash headed by the National Transportation Security Board.

The crew of a Sikorsky UH-60 Black Hawk that fatally struck a commercial airliner was assigned to a Virginia-based VIP transport unit and was performing an annual night proficiency flight at the time of the incident.
