It's been reported that an FAA analysis after the first crash concluded that - without modification - MCAS was expected to cause an additional 15 crashes over the service life of the 737 MAX. It seems that when the second aircraft crashed Boeing was already working on a new version of MCAS, but they and the FAA decided to keep this quiet and keep the aircraft flying. I think that this decision accepted rather a lot of risk to life, compared to what I would expect from civil aviation. "Peter Defazio, the chairman of the House Transportation Committee, said an FAA analysis following the Lion Air accident but before the Ethiopian Airlines crash concluded there would be 15 fatal MAX accidents if there was no fix to MCAS. DeFazio asked Dickson why wasn’t airplane grounded then? He did not have an answer." https://leehamnews.com/2019/12/11/faa-no-max-certification-until-2020-analysis-forecast-15-more-crashes-if-mcas-not-fixed/ https://leehamnews.com/2019/12/11/faa-no-max-certification-u...
