yanrair, I think you and I would disagree on apportionment of ultimate responsibility, but there is no escaping the fact that MCAS was a rather simplistic sticking plaster. For sure, lawyers will do their thing and we will continue to argue over ‘kludges’, airmanship etc, but can anyone seriously deny that the 737 has evolved as far as it can? Boeing have about 7000 or so on order; that should give them plenty of time to design the 737’s replacement, from scratch.
