Thank you, this is a very good summary of the issue. Only a small comment to 4: it was the Ethiopian Air flight, where they disabled MCAS but did not manage to regain control, mostly due to their air speed being too high. Lion Air had 2 MCAS incidents, the first on the day before the crash, where the pilots disabled electric trim control and continued the flight without an incident and the second, where they did not disable MCAS at all, leading to the crash. Interestingly, Airbus as a consequence of the events reviewed their flight software and also found an issue they are quickly correcting, but it seems that no planes are grounded as a consequence.
