Fascinating how many people had to actively shove this to the side so that it became potentially life threatening: - CFM designed an engine that, in certain emergencies, dumps oil into the quite possible (actually traditional, if I understand correctly?) human-breathing stream of the aircraft, apparently, without the relevant human-breathing system shutdown mandate when said (or any) emergency system is triggered; [truth be told, we never heard their complete story] - Boeing integrating said new engines into their new 737MAX without appropriately checking for possible new emergency mode interactions with their life-support (in this case, breathing) systems. - FAA dropped the ball upon accident investigation; - FAA removed their employee that then picked up the ball; - EASA swallowing what they were told by FAA without asking further questions; Well... I have worked in many no-harm potential software projects that employed more careful engineering than this. All hardware projects I worked on employed more careful engineering than this. Conclusion: It becomes more and more difficult to falsify that Boeing, nowadays, simply abandoned engineering design reviews, and, relies solely on some blend of "agile" methods to design people-carrying airplanes.
