Which occurred during the Golden era (daniel golden) 
of cheaper, simpler, faster.  They tried to XP 
a complex craft and made a bad mistake in the 
rush.  

Oopsie.

The shuttle has five computers.  Computers 
don't help if you launch with ice hanging off 
engines with exposed creases sealed with rubber.

Oopsie.

Simplicity is good by itself.  Speed is good 
if you are in a safe passage.  Put them together 
and pray your luck hopes outs.  If it doesn't... 
oh well.  Hit the wall and let your family 
wish you had a harness on at the funeral.

Oopsie.

XP has been tried.  It has its problems too. 
The big one is:  competence.  To get around 
that, QA.  Failover to another system.

QA is not a good practice; it is an absolute 
cost of doing business.

I thought NASA had it pretty well sussed with the computers on the shuttle
(this might be apocryphal) - 3 systems running, if two agree then that's
your answer. But then of course there was that business about metric and
imperial units on the way to Mars...
