The wreckage of a military helicopter involved in a mid-air collision with a passenger jet that killed all 67 people on both aircraft was recovered Thursday from the Potomac River, federal officials said.

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.

More than a week after the deadly collision of a passenger jet and a helicopter, crews forged ahead with salvage efforts in the Potomac River.
