There is a series called “Mayday-Air disaster” streaming free on many channels. Anyone who watches those episodes will get a fair good idea of what causes major airline crashes. It can be the plane, it can be the control tower. But the vast majority of them are pilot error. Stupid mistakes.
what makes it hard with Boeing is that they basically committed mass murder multiple times because the design flaws they produced with MCAS were so severe and negligent that even a 10 year old in my day could have seen it coming.
Even so I don’t agree with blaming them for things until all the facts are in. I am sure you are right about the DEI thing. It also equivalent to farming much of their software out to India which was a huge part(conceptually) in causing those 737 Max Disasters. But it was not the only cause.
I still believe that the stab switches should have a purely electric manual position(Not just auto, and off). And they did not change that. They should be able to fly by yoke alone if need be. That one change alone could have saved those planes. The pilots could have maintained reasonable control while telling the software that crashed the plane to F off. Just one more position on a mechanical toggle switch would have saved those planes.
It even had an occasional cartoon in it, a crusty old leather-helmeted guy named "Grandpa Pettibone" (I thought it was "Grandpa Dave" but...looking it up to be sure, it was "Pettibone")
But as a 19 year old sailor, I found the mishap reports fascinating and gripping reading. And the common thread through almost all of them (but not ALL of them) was human failure. I immediately recognized any of those guys they described installing a bolt the wrong way could be me.
