This is an important statement, partly because MCAS did what it was supposed to do - a mere extension of existing software, and if I were acting for Boeing, that would be my prime defence: There are many hundreds of small software processes going on at any one moment. At what level of complexity should Boeing be obliged to tell the customer/trainers just what is being processed?
Of course the MCAS software operated as coded.
It's not enough to operate effectively in normal conditions, the non-normal conditions (i.e., failure modes) must be safe as well.
I stand in solidarity with the grieving families.
Jobs and share prices "trump" aviation safety.
