I continue to find it disturbing and surprising that more than a few posts are focused on blaming, or at least strongly suspecting, crew error as a primary cause of the Ethiopian crash.
Surely, it should be clear, from all we have learned and discussed in the weeks since that accident, that the crew was faced with a situation that almost any crew would have found very difficult, if not impossible, to deal with successfully. If mistakes were made, they were made in an environment where not making mistakes was extremely unlikely and in which they would never have found themselves if the OEM and the regulatory authority had not made fundamental and extraordinary mistakes in designing and certifying the aircraft. And those entities weren't facing imminent sudden death when they screwed up.
