An American Airlines plane with 64 people on board collided with an Army helicopter over Washington, D.C., and crashed into the Potomac River.

I don’t know of any other accident that has had this amount of impact on aviation but also in other industries,” one expert said of the 1982 crash.

The Potomac River is open again after federal recovery teams concluded their salvage operations following the deadly collision between a commercial airliner and a U.S. Army helicopter on Jan. 29.

Crews have finished recovering the wreckage of a plane and helicopter that collided mid-air, killing 67 people.

Six days ahead of schedule, officials on Tuesday announced the section of the Potomac River affected by the deadly collision between an American Airlines jet and military helicopter had been fully restored.

In a major update, the US National Transportation Safety Board and the Federal Aviation Administration retrieved parts of the wreckage of the Black Hawk helicopter on 7. The helicopter collided with an American Airlines jet on January 30.
