    Hello Mr. Prinz,
    You have brought up a very good point re: the missing pages of the
    almanac. How ironic that in this case, the astro-navigator would have to
    resort to GPS as the backup!
    There is another electronic back up which is quite reliable and sturdy:
    the "Celesticomp" navigation calculator. I bought one from Celestaire
    several years ago and have never regretted the purchase. Although I still
    diligently practice reducing sights the old way (and that includes the use
    of trig and log tables), the Celesticomp is really useful for those times
    when you are taking dozens of sights for practice, and want quick answers.
    Astro-navigation's answer to instant gratification.
    On a related issue, which may be of interest to the list, it is a little
    known fact that when Roald Amundsen embarked on his historic journey to
    the South Pole in 1911-1912, he attended to every little detail (in
    characteristic Amundsen fashion), except for one thing: he forgot to bring
    along the 1912 edition of the Nautical Almanac (ref. Roland Huntford:
    Amundsen and Scott). Because of this, he was compelled to reach the South
    Pole (and fix his position there with absolute certainty) before the close
    of 1911. As it turns out, he did, on December 17. Talk about cutting it
    close eh?
