I had a teacher who used to work for Pratt& Whittney and told us the 
story of building his house.  He was so used to working with military 
specs that he built his house with tolerances in measured in microns. 
He says that on the first rainy day, none of the doors in his house 
would close.

(I have a feeling i was making this up, as you can't get that kind of 
precision with a circular saw... and I'm pretty sure he didn't use a 
5-axis CMC mill to build his door frames.)
