The bodies of all 67 people killed when an American Airlines plane and a US Army helicopter collided at Ronald Reagan Washington National Airport have been recovered, according to officials.

So far, 66 of the bodies have been positively identified, Unified Command officials overseeing the recovery mission announced Tuesday.

“This marks a significant step in bringing closure to the families and the community,” officials said in a statement.

“Our hearts are with the victims’ families as they navigate this tragic loss. We extend our deepest condolences and remain committed to supporting them through this difficult time,” they added.

Of the deceased, 60 were passengers on the plane and four were flight crew.

The helicopter was carrying three crew members.

Most of the plane has been recovered from the frigid Potomac River, and the recovery effort has now pivoted toward pulling the remains of the helicopter from the water.

Barges carrying cranes have been lifting pieces of the aircraft from the river since shortly after the Jan. 29 crash.

The plane’s black box has been recovered, and revealed that the plane was at 325 feet when the collision occurred – meaning the helicopter was well above the 200-foot ceiling that choppers are restricted to over the Potomac.

And the American Airlines pilots appeared to have attempted to pull up just moments before the impact, suggesting they might have been trying to avoid a collision.

The helicopter was flying a training mission to re-qualify the pilots for flight in the area – something they’d done several times before, according to deputy director of aviation for the Army Col. Mark Ott.

“These were two experienced, qualified pilots to fly in this local area,” Ott said of the chopper pilots.

“This is something they’ve done many times before, and they were simply out flying a training mission that’s required to re-evaluate, just like every Army pilot does on an annual basis,” he added. “You get re-evaluated, re-signed off to fly in your local area.”
