Nothing to do with this being untested software then?  Actually it was 
so I'd put that down to a programmer error.  "The code always worked 
before so it's bound to work this time".  Such a pity that this 
particular launch wasn't the same as anything done previously.

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
