The mangled remains of the Black Hawk helicopter involved in last week’s deadly midair plane crash in DC were pulled out of the Potomac River Thursday, the National Transportation Safety Board announced.

Crews working at the site of the deadliest aviation disaster in a generation have recovered all 67 victims of the collision between two aircraft over the Potomac River in Washington, DC, officials said Tuesday.

The Army helicopter that collided with a passenger plane above the Potomac River boasted an experienced crew doing “an unforgiving job.” Friends and relatives are still baffled and mourning their loss.
