>"I would be very surprised if in a few years from today a bunch of engineers don't testify that ample of warning was given to management about this. "

I love this mentality that "managers" are the only people responsible, and that the people actually putting the thing together are not. It's the same with the bank scandals, or the VW scandal, or the Facebook scams; it's all the executive team! We were just peons following orders! We aren't responsible!

If you see a major safety issue or other concern, and report it to your superior, who does nothing, you're pretty weak if you shrug your shoulders and say, "I did my job!"
