A passenger jet collided with a helicopter while landing at Ronald Reagan National Airport on Wednesday evening, prompting a large search-and-rescue operation in the nearby Potomac River.

There was no immediate word on casualties, but all takeoffs and landings from the airport near Washington have been halted.

Here’s the latest:

Noem says all available Coast Guard resources being deployed

Homeland Security Secretary Kristi Noem said she would be deploying all available resources from the U.S. Coast Guard for search and rescue efforts.

“We are actively monitoring the situation & stand ready to support local responders,” Noem said in a post on X.

Reagan Washington National a popular airport

Reagan Washington National is located along the Potomac River, just southwest of the city. It’s a popular choice because it’s much closer than the larger Dulles International Airport, which is deeper in Virginia.

Depending on the runway being used, flights into Reagan can offer passengers spectacular views of landmarks like the Washington Monument, the Lincoln Memorial, the National Mall and the U.S. Capitol. It’s a postcard-worthy welcome for tourists visiting the city.

Details on the passenger jet

American Airlines flight 5342 was inbound to Reagan National at an altitude of about 400 feet and a speed of about 140 miles per hour when it suffered a rapid loss of altitude over the Potomac River, according to data from its radio transponder.

The Canadian-made Bombardier CRJ-701 twin-engine jet was manufactured in 2004 and can be configured to carry up to 70 passengers.

Trump is briefed on the crash

White House press secretary Karoline Leavitt says President Donald Trump has been briefed on the crash.

‘Tower, did you see

that?’

In audio from the air traffic control tower around the time of the crash, a controller is heard asking the helicopter, “PAT25 do you have the CRJ in sight,” in reference to the passenger aircraft.

“Tower, did you see that?” another pilot is heard calling seconds after the apparent collision.”

The tower immediately began diverting other aircraft from Reagan.
