Briefing
Investigators have recovered the flight data recorders, also known as black boxes, from an American Airlines  plane that collided with a  U.S. military helicopter on Wednesday near  Washington, DC.
The National Transportation Safety Board said it has "a lot of  information, but ... it needs time to  verify" and  that a preliminary report will be  released within 30  days.
Details about some of the 67 people who died in the crash are now  starting to  emerge.
President Donald Trump  expressed his  condolences, saying Thursday  that "our hearts are  broken" by the  tragedy.
Trump has lashed out at diversity rules under his predecessors, saying he believes people hired for air traffic control  positions are not always qualified  — but  has provided no evidence  of this.
In a video clip, air traffic controllers can be heard asking  helicopter crews if they can see the  plane.
