While authorities focus on the cause of the US's deadliest aviation disaster since 2001, families are mourning their loved ones. Here's the latest.

A multi-agency search and rescue operation is underway in the Potomac River after a small American Airlines aircraft collided with an Army helicopter near Reagan National Airport, authorities confirmed.

A midair collision between an Army helicopter and a passenger jet killed all 67 people aboard the two aircraft, officials said, as they search for answers in the nation's deadliest aviation disaster in nearly 25 years.

U.S. authorities said on Thursday it was not yet clear why a regional jet crashed into a U.S. Army helicopter at a Washington airport, killing 67 people in the deadliest U.S. air disaster in more than 20 years.

Investigators confirmed they have recovered a cockpit voice recorder and a flight-data recorder from American Eagle Flight 5342, which will undergo analysis.
