re: 11 of the most costly software errors in history VIEW POST


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 :)
