You didn't answer any of the points raised by non Asians except calling them stupid and instead provided sales figures. MAX had orders of almost half of all 737 sales before it was grounded. 737 when it came was better than what was available and once airlines go for a brand they are reluctant to change Boeing kept offering tinkered versions which suited any requirement and nothing much was available till the entry of A320. Then they had to plan for the future but the buying MD, 787 initial losses prevented that. Instead they tried to drag 737 for one last time which delivered Boeing a body blow. How can MCAS be fitted without redundancy when another AOA sensor was available beats me.
