I thought the same thing with the groupthink at NASA. It's hard to put in perspective just how badly NASA management screwed up though--probably much moreso than here. I would bet 90%+ of HN user's great grandmothers would not make the same mistake. Of course they wouldn't--it takes a special case of narcissistic manager who can both get himself to the top and also tell his engineers no because he cant admit a mistake and would rather risk blowing up a space shuttle (and it happened).
