If you are interested, you can read the IAEA (?) incident report and the translation of the latest, not hiding anything, report from Soviet authorities. Both are available online, and both should be mandatory reading in any engineering studies. For both, how to investigate incidents and what to learn from incidents / how incidents can happen.

Because the final Soviet report (the series over dramatized in the last episode) is really good. For added fun, read the official incident reports on the 737 Max and compare both. Because the parallels are staggering.
