Here is a short story to show you that the stodgy air traffic controllers and the flyers they serve can have a sense of humor: The controller who was working a busy pattern told the 727 on downwind to make a three-sixty (to do a complete circle, usually to provide spacing between aircraft). The pilot of the 727 complained, "Do you know it costs us two thousand dollars to make a three-sixty in this airplane? Without missing a beat the controller replied, "Roger, give me four thousand dollars worth!"
