Thanks, Mike. Might you have a technical, rather than an emotional, reaction to share?

So you are suggesting that he is at least as confident that he won't die, flying in a MAX, as he is 
that 2+2=4 ? Or should that confidence be relativised somehow?

Yes. And that the defined procedures are not enough has been pointed out twice in reports.

After Ermenonville, the DC-10 became "the most scrutinized [sic] aircraft in the history of the 
commercial transport fleet." Then came Sioux City. Along with nobody noticing that you could lose 
structural integrity if you lost pressure in one half of the PV (which led to Ermenonville through a 
couple of other occurrences), nobody apparently noticed that they had routed all the control system 
hydraulics through one spot in the tail, which was duly sliced through by a shed blade. Many put 
that down to the overall design process of the airplane and worried about other oversights. Which 
ended up being, some say, why the DC-10 fleet converted to freighters, followed quite quickly by the 
MD-11.
