I entered an engineering school 5 years after Ariane V. Each single professor explained us why their subject was the reason for Ariane V to explode. The physics one went about how the imperial/metric discrepancy was the cause, the mechanics one went about how error margin management wad the cause, the CS one about integer overflow... Each of them made it clear that their course was the center of the world, but altogether it didn't look smart. I chose that the CS guy was right ;)
