So if even NASA (see, e.g., Challenger and Columbia accidents) is not immune to this kind of culture as 'exposed' by this documentary, why do we expect/insist for-profit corporations to do better? The fact of the matter is we can 'uncover' these sorts of thing in all human endeavors. Sadly, it is part of the human condition that we stumble along, repeating the same mistakes because of our inherit (insert-your-favorite-human-frailties-here) nature.
