    " It is also intesting to note that, near as I can reckon, the nautical mile
    has never been abandoned by the aviation and marine industries in favour of the
    kilometer. "

    Incidentally, in the US, our airline industry *has* in fact abandoned the
    nautical mile, if they ever used it. While pilots may still use knots and
    nautical miles (I don't know how they'd vote) if you ask any US air carrier they
    will tell you airspeeds and distances in plain statute miles and mph. They tend
    to schedule aircraft at a convenient 500 statute mph these days, which is also a
    bit less fuel thirsty than what the aircraft really can do. I don't know of any
    official policies or pronouncements about this, that's just what "every" carrier
    in the small number I've dealt with in the past ten years has used.
