when i was young i suspect on the sky have a traffic like on the ground or not. It was communication between pilots and controller to take a plane go to the destination and tell direction which a plane should go. If have not controllers, it can occur an accident. It so excited to think about controlling a traffic for the plane. I think it challenge for me to do it and i think i can do it if i recieve chance that learn about air traffic control. It would be an opportunity for me to finally learn and do.
