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 and tell direction for the plane. I think it challenge for me to do it. If i recieve chance that learn about air traffic control, i think i can do it. It would be an opportunity for me to finally learn and do it in future
