" 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.
