A PSA Airlines Bombardier CRJ700 regional jet collided with a Black Hawk helicopter while on approach at Reagan Washington National Airport at about 9 p.m. Wednesday.

For many, the Sikorsky UH-60 Black Hawk helicopter, like the one involved in the Wednesday collision over the Potomac River in Washington, D.C., is familiar for one reason: the 2001 movie "Black Hawk Down ," based on the 1993 shooting down of U.S. Black Hawk helicopters during the Battle of Mogadishu in Somalia.

Sixty passengers and four crew members from the plane and three Black Hawk helicopter personnel are feared dead as a recovery mission is underway.
