    Frank, let's not forget the part between the navigator's ears. :-)

    Quoting an experienced navigation instructor:
    "I now make it a point to all navigators that sextant, chronometer and tables comprise just as much of a 'black box' as does satellite navigation. Has anyone silvered a mirror lately in an emergency, or perhaps repaired a chronometer? Celestial navigation is merely an old fashioned 'black box' requiring a bit more of the navigator..."

    Is this a fair statement today? Is celestial a 'black box'? Just curious to hear opinions on the matter.
