Ronald Reagan National Airport was the scene of a recent near miss and control tower brawl, more than two months after a collision killed 67 people.

Air traffic controllers at Washington's Ronald Reagan National Airport will be offered crisis counseling and additional supervision after a fight in the tower and another alarming near miss two months after a midair collision between a passenger jet and an Army helicopter killed 67 people.

The arrest of an F.A.A. employee on assault and battery charges comes as flight operations at the airport have been under scrutiny since a passenger jet and an Army helicopter collided in January.
