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:


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?

Thanks Phil. I updated the broken link and also added your MIT link, thanks for providing that :)
