    Actually course was never path through the air, for instance. If you want to
    go from A to B, you would draw a line from A to B. That is your course. If
    there is a cross wind, your heading would be different from your course. If
    you were leaving contrails, the path through the air would be visible, but
    it would not have the same angle as your course. Unless there was no cross
    wind, ---- Of course ;)
