Sometimes in engineering, what appears to be the problem really isn’t.
It is possible that they haven’t found the real cause of the crash.
A good crew looks at a lot of variables before freaking out and over-correcting. An inexperience crew goes in full panic mode when one instrument is “off”.
Boeing looks to be at fault though because glitches of any kind should not happen. If they do, the whole fleet should be grounded on the spot.
