The wreckage from both the plane and the helicopter will be taken to a hangar to be examined as part of the investigation into what led to the mid-air collision near Ronald Reagan Washington National Airport last week that killed 67 people on both aircraft.

Two Metropolitan Washington Airports Authority employees have been arrested and charged with leaking official airport records after apparent surveillance footage from Reagan National Airport showing last week’s collision between an American Airlines jet and an Army Black Hawk helicopter was shown on CNN.
