Point of order. The Titanic wasn't really a failure...
As a morality play on human hubris it's entered the popular culture but the simple truth is that Titanic met circumstances that exceeded the imagination of her designers.
And in those circumstances she performed far beyond the expectations of her designers - and arguably, better than a modern ship. She remained afloat and stable for two hours - time enough for an evacuation of the ship to be more than completed if necessary.
Everyone who designed her and operated her acted in a rational and intelligent manner, according to the best standards, practices and assumptions of the time. Unfortunately, the limitations of those practices were proved to be disastrously wrong.
Arguably, what Titanic suffered from most was a Captain with no disaster management training, who froze at the culmination of disaster, and a whole load of holes in the swiss cheese lining up in just the wrong way. Everything from lost binoculars, to nearby ships having their radio off. It is, ultimately, the worst of luck and all the conspiracies of fate, rather than hubris that sank the Titanic.
If you want a metaphor for a disaster caused by retarded incompentence, pic related.
Sorry. But this really bugs me.
