The U.S. Federal Aviation Administration is indefinitely restricting helicopter flights near Washington Reagan National Airport after a deadly collision between an American Airlines regional jet and Army Black Hawk killed 67 people.

American Eagle Flight 5342 was seconds away from landing at Reagan National when it collided with the Army helicopter on Wednesday night.

On a fall afternoon, a Boeing passenger jet had just been cleared for takeoff at Reagan National Airport when the pilot saw a Bell helicopter lift off in a direction that would cross the plane’s path. The airplane pilot aborted the takeoff, overrunning the runway before coming to a stop on a grassy strip just 130 feet from the Potomac River.
