There are likely no survivors after an American Airlines plane and an Army helicopter collided in the air over Washington DC Wednesday night — as the search and rescue operation has now become a recovery mission, officials said.

The American Airlines flight traveling from Wichita, Kan., collided with the military chopper while approaching Runaway 33 at the DC airport around 9 p.m., according to the Federal Aviation Administration.

First responders have recovered at least 19 bodies from the river as of early Thursday, CBS reports.
