The wreckage of a Black Hawk helicopter that crashed into a plane above the Potomac River has been recovered from the water.

Footage captured by the National Transportation Safety Board shows the recovery of a Sikorsky UH-60 military helicopter from the river near Ronald Reagan Washington National Airport on February 7.

Investigators continue to assess the debris for further analysis.

The devastating mid-air collision between an American Airlines Bombardier CRJ-700 and a U.S. Army Sikorsky UH-60 Black Hawk happened on January 30.

All 64 people onboard the American Airlines plane were killed. There were 60 passengers and four crew members on the jet, while three service members from the military were onboard the helicopter, which was on a training flight.

The CRJ-700, operated by PSA Airlines, was manufactured in 2010 and registered as N530EA. The UH-60 Black Hawk, a military staple since 1979, has served in major operations worldwide.

Despite their reputations as reliable workhorses in commercial and military aviation, both aircraft plunged into the river following the catastrophic collision.

Ronald Reagan National Airport is in the centre of the nation's capital, near major federal institutions including the White House and Congress. It is also across the river from The Pentagon, the U.S. Department of Defence, in Arlington, Virginia.
