Clearly the FAA, with its aircraft population exceeding the rest of the known universe's about 10 times, has got it wrong, and N-reg planes are plummetting from the sky everywhere, because their pilots are trying to do wind correction calculations and are finding their batteries have gone flat.
Is there any other human activity that is more anally retentive than this?
The stupid ridiculous slide rule (which, incidentally, I
do know how to use from first principles having used them for real engineering calcs in the late 1960s) belongs into an era long displaced by those weird gadgets with buttons on them, powered by either daylight, or by batteries that last far longer than most users can remember.
