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, the head of Army aviation told The Associated Press on Tuesday.
Investigators are still determining why the Army helicopter and the American Airlines jet collided near Ronald Reagan National Airport on Jan. 29, but the Federal Aviation Administration has data showing an alarming number of close calls around the airport.
