Hello This is Harry Downs, an avid scanner listener on air frequencies. I always here pilots stating see you later or good morning, to and from etc leaving one controlled air space and then entering into another. Basically iti s a handing off transmission, professional way of gestures and greetings and platitudes between air traffic control and pilots. How come none of the experts on your shows related this detail as it seems as it is a subversive phrase being drawn down to be deviant. of the pilots etc. Please have some one clarify this so to dispel negative connotations on this phrasology. email@example.com 413-684-1458. I also am available on skype. Schedule tomorrow , I have to take son back to Framingham State University should be back by 6pm EDT Then in office at number above Monday . but have voicemail as well.
