On the flip side, all airplanes have flaws to some degree or else they would never crash. A deep audit of everything in the end should make things safer. And Boeing also has a solid safety record on their other models 777 and 767
The problem for Boeing is the history of flying has many examples of planes with poor safety records being rejected by the flying public.
Only time will tell if the 737-MAX joins that illustrious group, but the more the plane stays in the news for all the wrong reasons, the better are it's chances.
USAir Flight 427
United Airlines Flight 585
Eastwind Airlines Flight 517
Silkair Flight 185
Copa Airlines Flight 201
China Southern Airlines Flight 3943
MetroJet Flight 2710
But there are also many examples of aircraft with terrible early safety records that never recovered from their bad start.
From Boeing? They have a history of sorting their shit out. Maybe this time is different, but I doubt it.
They also seem to have a bad habit of blaming the dead pilots for not being able to fly they broken planes.
You seem to be overlooking the 787 - a few early models set on fire. Sure, nobody died, but that was more luck than judgement.
You could have a perfect aircraft with no flaws, and a human could still manage to crash it. See the Germanwings flight for a good example.
If not you have a lot of faith in people's willingness to sacrifice themselves to save others.
