Quoting from (CNN) These are the mistakes that cost Boeing CEO Dennis Muilenburg his job (red highlights mine),
…While the plane was still in the process of being certified, Boeing pilots were sending messages to each other questioning whether the safety system would work as intended. And a Boeing whistleblower recently testified to Congress that he tried to alert superiors about the problem with the production line ahead of the Lion Air crash, and then again ahead of the Ethiopian crash, only to have his concerns ignored.
[Space Shuttle Challenger]…America needed a hero to investigate the heroic. Feynman filled that role, but his account varies from the myth. According to Feynman, individuals volunteered the necessary information, organized in away to lead him to the conclusion. Feynman said he never would have found it on his own.
They knew the answer before Feynman. (Wikipedia) Space Shuttle Challenger disaster, shows that at the engineering level, there was a vibrant safety culture, cognizant of what Feynman eventually discovered, that failed to influence management.
With ever-changing names, this time, “Boeing”, it plays out like a Passion Play unchanged by centuries. In 2014, it was the GM ignition switch, responsible for 124 deaths. In 2011, it was the Fukushima Daiichi nuclear disaster. This was preceded by the Financial crisis of 2007–08.

Even without provocation from Nature, the play runs every three to four years. Only the names of the actors change: An airplane, a ten cent ignition switch part; an abstract system involving abstract money. In between productions, hucksters push bogus pay-me schemes to manage risk.
What would it take to cancel the next production of this play?
