Several figure skaters, along with their coaches and families, were traveling on an American Airlines plane that crashed into an Army helicopter near Ronald Reagan National Airport in Washington D.C.

As investigators try to uncover what happened when an airplane and a helicopter collided over the Potomac River, here is the latest information.

Air traffic controllers asked Flight 5342 to switch runways when coming in to land. Black box recordings from the jet and the military helicopter it collided with will help reveal whether this contributed to the accident.
