United States authorities have restricted helicopter flights near Reagan Washington National Airport indefinitely after a mid-air collision between a passenger jet and a military helicopter killed 67 people.
Officials said that 41 of the victims' bodies had been recovered by Friday.
The Federal Aviation Administration restricted helicopter flights to reduce the risk of another collision as crews worked to pull the wreckage of America's deadliest air disaster in two decades from the Potomac River.
An FAA official told Reuters the agency was barring most helicopters from parts of two routes near the airport and only allowing police and medical helicopters in the area between the airport and nearby bridges, pending a complete evaluation. It was not clear how long those restrictions would last.
Washington DC's fire chief John Donnelly told reporters that 28 of the bodies recovered so far had been positively identified.
"We expect to recover all of the bodies," he said. "That's why our teams are still working."
Donnelly said moving the plane's submerged fuselage should improve access to more bodies.
Terry Liercke, vice president of Reagan National, said two of the airport's three runways were expected to remain closed for a week. The main runway at Reagan handles about 90 per cent of flights and is the busiest single runway in the United States.
Crash highlights air safety concerns
The crash has cast a harsh spotlight on questions about air safety and a shortage of tower controllers at the heavily congested airport that serves the US capital.
Airspace is crowded around the Washington area, home to three commercial airports, multiple military bases and some senior government officials who are ferried around by helicopter. Over a three-year period ending in 2019, there were 88,000 helicopter flights within 48 km of Reagan National Airport, including about 33,000 military and 18,000 law enforcement flights, the Government Accountability Office said in a 2021 report.
The American Airlines plane was trying to land at Reagan National Airport when it collided with an Army Black Hawk helicopter and crashed into the Potomac River on Wednesday evening. Fresh from recovering the plane's so-called black boxes, divers aim to salvage both aircraft and find additional components on Friday, Washington's fire department said.
Authorities have not pinpointed a reason for the collision.
The National Transportation Safety Board is studying the cockpit voice recorder and flight data recorder from the CRJ700 airplane, which carried 60 passengers and four crew members, all of whom perished in the crash. The three members of the helicopter crew also died.
One controller rather than two was handling local plane and helicopter traffic on Wednesday at the airport, a situation deemed "not normal" but considered adequate for lower volumes of traffic, according to a person briefed on the matter.
Transportation Secretary Sean Duffy vowed to reform the FAA.
The military said the maximum altitude for the route the helicopter was taking is 61 metres but it may have been flying higher. The collision occurred at an altitude of around 91m, according to flight tracking website FlightRadar24.
Trump claims helicopter was 'flying too high'
US President Donald Trump weighed in on Friday, saying that the helicopter involved in the crash was flying too high.
"The Blackhawk helicopter was flying too high, by a lot. It was far above the 200 foot limit" he said in a Truth Social post.
Senator Maria Cantwell, the top Democrat on the Senate Commerce Committee, questioned the safety of military and commercial flights separated by as little as 107m vertically and horizontally. She also urged the government to reconsider allowing so many helicopter flights next to such a busy airport.
Radio communications showed that air traffic controllers alerted the helicopter about the approaching jet and ordered it to change course.

Seven US pilots told Reuters that the landing at Reagan airport is unique due to congested space along with an inability to communicate directly with military aircraft, which operate on different radio frequencies. The airport also has shorter runways.
The crash victims included people from Russia, China, Germany and the Philippines, as well as young figure skaters and people from Kansas, the state from which the passenger flight took off.
