Exactly so.

Mission critical systems are built to be tolerant of small errors. 
It is the small error that turns into a big one (the cascade) that 
one dreads.  For example, when the missile fails to take off and 
you only find out after the other one is in the air.  Or the humanIntheLoop

when a sub-sub-sub contractor decides to save a few shekels in 
manufacturing, doesn't stiffen the board, it shakes loose in flight, 
and it has the component that tells the warhead to separate.  

AKA, oooopsie...

The truly bad one is the unk-unk:  unknown-unknown.

I wouldn't be so sure. You can spend billions on cataloguing all your
information and still make laughable mistakes.
