Indeed: As in most air accidents, nothing is wholly on anyone's shoulders. Everyone has their part to play in safety (and that includes us passengers). But even on the basis that the part should have been a good one given its provenance, how that defective part came to be flying on the accident aircraft on the accident flight is also a thoroughly dismal story. And so far as the airline is concerned, nobody expected there to be an accident - so there is ample room for suspicion that what happened at the airline is just business as usual there. Personally, that frightens me considerably more than the analysis of whether Boeing has or hasn't done enough in the post-grounding changes to the MAX.
