The National Transportation Safety Board says it has recovered a cockpit voice recorder and flight data recorder from the American Airlines plane that collided with an Army Black Hawk helicopter near Reagan National Airport late Wednesday.

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

Dozens of people are dead after a regional jet collided with an Army Black Hawk helicopter Wednesday night over Washington, D.C., officials said, the nation's first major commercial airline crash since 2009.
