Recovery efforts are ongoing on the Potomac River as the weather allows, according to the National Transportation Safety Board (NTSB).

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.

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.
