A very good overview of Boeing's history particularly after its merger with McDonnell Douglas, which the author argues was a turning point from an engineering worldview to one of bean-counting. It chronicles the spinoff of engineering functions and the way the American FAA allowed Boeing to be its own regulator and inspector. It was written in the wake of the twin 737 Max tragedies, which are a primary focus, but the seeds are sown for all the bits falling out of the sky that we've seen of late.
