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.

U.S. authorities restricted helicopter flights near Reagan Washington National Airport on Friday, after a midair collision between an American Airlines passenger jet and a military helicopter killed 67 people this week.

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