>P.S. In my previous life as an electronics engineer I was a Metrologist. We used metric and English systems of measurement - metric being of more importance.

I remember (i think) the Mars Polar Orbitor - I was hot for that one to be a success - imagine the stuff a rover might have found near the ice on Mar's north pole! - but it was farkled becase SAE was implemented for a metric requirement.

Whose foot did the foot come from? Was King James or King John? Tall for a guy back then!
