Dozens feared dead after American Eagle jet and Army helicopter collide and crash into Potomac River

 A commercial plane and a military helicopter collided midair near Reagan Washington National Airport on Wednesday night.

Both of the aircraft — an American Eagle jet and Army Black Hawk — are in the Potomac River. There were 64 people on the plane and three in the helicopter.

The incident occurred shortly before 9 p.m. ET. The number of casualties is unclear, as a search-and-rescue operation is ongoing.

President Donald Trump said in a statement Wednesday night that he has been fully briefed on the crash. He thanked first responders and said he “will provide more details as they arise.”

The airport is closed until at least 11 a.m. Thursday.
