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.

The National Transportation Safety Board says it has recovered a cockpit voice recorder and flight data recorder from the American Airlines plane that collided with an Army Black Hawk helicopter near Reagan National Airport late Wednesday.

Sixty passengers and four crew members from the plane and three Black Hawk helicopter personnel are feared dead as a recovery mission is underway.
