Big Bang
In which we know why things explode
I know it’s only a few hours since the Buncefield oil storage depot exploded, but I’d like to jump in already and hazard a guess as to what the primary cause was. The immediate cause will no doubt be something like a leaky joint and an unexpected spark; but the primary cause will probably end up being reactionary maintenance policies: engineers being instructed not to replace anything until after it’s already broken.
