The American Airlines flight involved in the deadly collision with a Black Hawk helicopter over Washington, DC, seemed to increase its pitch just before the impact, preliminary data from a voice data recorder recovered from the plane shows.

The plane's altitude suggests the Army helicopter was flying above 200 feet − the maximum altitude for the route it was using.

Data retrieved from an American Airlines regional passenger jet and a U.S. Army helicopter that collided last week in Washington over the Potomac River killing 67 people will be released on Monday, National Transportation Safety Board Chair ​​​​​​​​Jennifer Homendy said in an interview on Fox News.
