Jornal Do Brasilia - Bodies pulled from Washington river after plane collides with helicopter

A massive search and rescue operation was in progress, with divers visible in the glare of powerful lights as they plunged into the snow-lined Potomac to scour the wreckage of both aircraft.

Washington Fire Chief John Donnelly told a press briefing that emergency crews, totaling about 300 people, were working in "extremely rough" conditions and gave little indication they expected to find anyone alive.

"We're going to be out there as long as it takes," Washington Mayor Muriel Bowser told reporters.

Citing local sources, CBS News said at least 18 bodies had been recovered, while NBC reported more than a dozen.

US Figure Skating said several athletes, coaches and officials were aboard the flight, while officials in Moscow confirmed married Russian couple Evgenia Shishkova and Vadim Naumov -- who won the 1994 world pairs title -- were on the jet.

"We unfortunately see that these sad reports are being confirmed. Our other fellow citizens were there," Kremlin spokesman Dmitry Peskov said.

The Bombadier plane operated by an American Airlines subsidiary was approaching Reagan National Airport at around 9:00 pm (0200 GMT) after flying from Wichita, Kansas, when the collision happened.

US Army officials said the helicopter involved was a Black Hawk carrying three soldiers on a "training flight".

Witness Ari Schulman was driving home when he saw what he described as "a stream of sparks" overhead.

"Initially I saw the plane and it looked fine, normal. It was right about to head over land," he told CNN.

"Three seconds later, and at that point it was banked all the way to the right... I could see the underside of it, it was lit up a very bright yellow, and there was a stream of sparks underneath it," Schulman added.

"It looked like a Roman candle."

- Trump criticizes traffic control -

President Donald Trump said in an official statement that he had been "fully briefed", and added of any victims, "may God bless their souls."

Less than four hours after the disaster -- and while other officials stressed they were waiting for investigations to unfold -- he took to social media to critique air traffic control.

"The airplane was on a perfect and routine line of approach to the airport. The helicopter was going straight at the airplane for an extended period of time. It is a CLEAR NIGHT, the lights on the plane were blazing," Trump wrote on his Truth Social platform.

"Why didn't the helicopter go up or down, or turn. Why didn't the control tower tell the helicopter what to do instead of asking if they saw the plane. This is a bad situation that looks like it should have been prevented. NOT GOOD!!!"

The Federal Aviation Administration ordered the grounding of all planes at Reagan National and the airport was not due to reopen until 11:00 am (1600 GMT) Thursday.

American Airlines' chief executive issued a video statement in which he expressed "deep sorrow", while US Senator Roger Marshall of Kansas called the collision "nothing short of a nightmare."

- Crowded airspace -

It was unclear how a passenger plane with modern collision-avoidance technology and nearby traffic controllers could collide with a military aircraft over the nation's capital.

The airspace around Washington is often crowded, with planes coming in low over the city to land at Reagan Airport and helicopters -- military, civilian and carrying senior politicians or officials -- buzzing about both day and night.

The same airport was the scene of a deadly crash in January 1982 when Air Florida Flight 90, a Boeing 737, took off but quickly plummeted, hitting the 14th Street bridge and crashing through the ice into the Potomac River. Seventy-eight people died.

Investigators concluded the pilot had failed to activate sufficient de-icing procedures.

The last major fatal US air accident was in 2009, when Continental Flight 3407 from New Jersey to Buffalo, New York crashed and killed all 49 people aboard.
