Wasn't a Mars orbiter ($US125 million space toy) lost because NASA was 
using metric units and another company was using imperial and the two 
teams effectively couldn't agree on how to send instructions to the probe? 

Incidently, the problem was only found after the orbiter had made it all 
the way to Mars and was about to commence orbiting.
