An American Airlines regional jet went down in the Potomac River near Ronald Reagan Washington National Airport.

A flight crew from Charlotte was onboard a plane that collided with a military Black Hawk helicopter over the Potomac River by Washington, D.C., according to multiple media reports and at least one crew member’s family.. A total of 67 people died — 60 passengers, four crew members on the commercial plane and three people on the military chopper.

Wednesday night’s crash of an American Airlines commuter plane in Washington could be one of the worst disasters for the Fort Worth-based airline in more than two decades.
