Thanks Nick, good to be reminded that we can all make bigger mistakes! Possibly my favourite expensive 'bug' to date, creating null references :)

Your link for the Ariane 5 flight 501 failure seems broken, this MIT write up is pretty official:

sunnyday.mit.edu/accidents/Ariane5...

which notes that engineers didn't need to 'hit the self destruct', as flight 501 broke up and self-destructed autonomously, after a series of failures induced by gaps in testing and communication between CNES and industry suppliers.. big project teams eh?
