all I've heard about this guy is that he ignored warnings, cut corners, and that he was a wealthy dude who's never had to deal with anyone telling him no his entire life. in all the reporting I haven't heard anything at all that would make me say "he got that right at least" and I challenge anyone to come up with something.

also when engineers disagree with each other you generally don't continue to use the topic of disagreement as a passenger vehicle. Finally, the guy making decisions wasn't an engineer and as far as I've heard no actual engineers who were well informed on the subject and experts in the domain were supporting this guy.... so what you should have said is "management disagree with engineers and dismiss their opinion all the time, often leading to high public catastrophes like the Challenger and the Titan"
