Officials in Washington, D.C., confirmed on Tuesday that all 67 victims have been recovered from the Potomac River during a multi-day unified recovery operation following the midair collision between a commercial plane and a U.S. Army Black Hawk helicopter last week, and that 66 bodies have been positively identified.

The identification, officials added, marks a significant step in bringing closure to the families and the community.

Of the 67 victims recovered, 60 were passengers on American Airlines flight 5342, four were crew members on the flight, and three were on the Black Hawk helicopter.

Officials have been at the debris site in the river since shortly after the collision between a Sikorsky UH-60 Black Hawk helicopter and a Bombardier CRJ700 airliner operating under PSA Airlines, a subsidiary of American Airlines.

While air traffic control data had the plane’s altitude at 200 feet at impact, Inman said they “have not finalized that and need to get more granularity to it,” and that data from the Black Hawk’s recorder is also needed to answer for the apparent 100-foot difference in altitude.

Although the data is available, it could take time to fully understand what caused the crash that night.

Military and other government helicopters fly this route almost daily, according to a senior Army pilot and warrant officer.
