The bodies of 67 people killed in a collision between a passenger plane and a military helicopter near Washington, D.C., have been recovered from the Potomac River, officials said Tuesday. All but one victim has been positively identified.

"Our hearts are with the victims’ families as they navigate this tragic loss," a statement from Unified Command says. "We extend our deepest condolences and remain committed to supporting them through this difficult time."

The crash occurred on Jan. 29, when the American Airlines regional jet traveling from Wichita, Kansas, was preparing to land at Reagan National Airport. The jet collided with a Black Hawk helicopter conducting a training flight.
