FDR, all true, including the expectation that a common horn sounding at 10,000’ wouldn’t get me to check the parking brake, but a licenced crew did in fact not recognise the horn was sounding “cabin altitude high” and a bunch of people died. Don’t forget just how far left the old bell curve stretches. By definition there are >50,000 flights a day operated by at least one below average crew member. That’s a lot of dice rolling.
Ultimately, a 737 Max will be flying on the 100th anniversary of the first flight. The perverse reality in that is there will be somewhere 100 years of systems development completely ignored in the service of expediency. Anyway, in competent hands the aeroplane is a money maker and currently enjoys an industry typical safety record. Its just a shame Boeing didn’t have the time, available talent or money to leapfrog the 320 and set the stage for the next 50 years.
