Airbus has been very professional in their media releases, but I think it's clear there are limits to what they can disclose without seemingly preempting the official investigation. Airbus took up development test flights again, so it's also clear to me they have more than a hunch about what went wrong. The speculations of the media remain just speculations, however they don't appear like some of the contrived drivel we usually see. The ECU issues from the AOT may be a random coincidence, but at least those speculations don't blame the deceased. With few exceptions this thread has also been very civilized, and this is what I wanted to express, besides my condolences: my relief that no one (not even armchair investigators, "experts", the media, or posters here) has come up with surreal conspiracy theories, this does restore some faith in humanity.
