The Army is telling The Associated Press that military air traffic controllers lost contact with an Army helicopter for about 20 seconds as it neared the Pentagon on the flight that caused two commercial jets to abort their landings this month at a Washington airport.

The Army has made changes to how its helicopters use a safety system that broadcasts aircraft location and has reduced the number of flights over Washington following a collision with a passenger jet that 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 head of the Federal Aviation Administration has told Congress that the agency must do more to ensure flying remains safe after a midair collision over Washington, D.

The Army was one of 28 government agencies authorized to fly helicopters near Ronald Reagan National Airport before its Black Hawk helicopter collided with an American Airlines passenger jet last week, killing 67.
