Really enjoy the videos and have learned a lot, and I'm not even a pilot. But here's a question I'm curious about. When your dealing with pilot deviation, severe mistakes, or even defiance. What happens to these pilots? Fines, suspensions? I heard one just a few days ago where the ATC was just doing his job and the pilot was not only rude, he was flat out defiant. When the ATC told him he was giving him a number to call the pilot flat out said he was refusing to call. What happens in those situations?
