An American Airlines passenger jet and an Army helicopter collided on Jan. 29 as the plane prepared to land at Washington, D.C.’s Ronald Reagan National Airport.

Federal aviation officials are taking urgent action to prevent future midair collisions after a catastrophic crash between an American Airlines passenger jet and a US Army helicopter over the Potomac River near Ronald Reagan

Current airport flight safety practices create an "intolerable safety risk" that could be eliminated by changing allowed separation distances between helicopters and airplanes, federal officials say.

The National Transportation Safety Board said the separation between helicopters and jets in the area was insufficient and increased “chances of a midair collision.”

The NTSB says the current helicopter routes around the busy airport "pose an intolerable risk to aviation safety" in the wake of January's collision that killed 67 people.

The NTSB’s preliminary report on the Jan. 29 crash that killed 67 people said current helicopter routes allowed around the airport are an ‘intolerable risk to aviation safety.’

More than a month after an American Airlines plane and a Black Hawk helicopter collided near Reagan National Airport (DCA), killing 67 people, officials with the National Transportation Safety Board (NTSB) are calling for immediate changes to helicopter routes around DCA because they said it poses “an intolerable risk

Investigators issued their preliminary report Tuesday in the probe into the devastating crash between an American Airlines plane and a U.S. Army Black Hawk helicopter.

Federal regulators say there's a "serious safety issue" in the airspace around Reagan National Airport in Washington, D.C. An investigation into the midair collision of a military helicopter and a regional jet in January found there have been many close calls involving planes and helicopters near the airport.
