    If I had arrived at the North Pole, would I not simply be starting out on a
    loxodrome heading south, on a bearing 180 degrees greater than the one I had
    arrived on at the North Pole, eventually to arrive at the South Pole?
    http://www.owlnet.rice.edu/~fjones/loxo.html.

    I visualized myself travelling on a ship through the North Pole on a
    constant bearing. Not vanishing into the ether in my mind, I then I drew
    the situation on a sketch map with the North Pole at the center, and the
    lines of longitude radiating out from the Pole. I drew my heading as a
    straight line entering the Pole at 045 degrees. According to the diagram,
    it appears that I would leave the Pole on a heading of 225 degrees.
