Helicopters will be permanently restricted from flying near Washington, D.C.'s airport on the same route where a passenger jet and an Army helicopter collided in midair, killing 67 people, the Federal Aviation Administration said Friday.

There's an "intolerable risk to aviation safety" with helicopters and planes flying too close to one another near DCA.

The Federal Aviation Administration announced a "series of steps" it will take to address safety concerns after a fatal midair crash near Ronald Reagan Washington National Airport.
