Agree with IngeMar! With my recent trip involved 2 problem aircrafts; one electrical wire fail, and the other with engin problem(same model of aircraft), I would like to know a bit more. With technet resourceful background in high rel asy, discussion could be beneficial to prevent future failure. Not say I can hand pick my aircraft upon travel, but picking an airline might be in the consideration for me in my future travel.

For the first time, I don't agree fully with you, Brian.
I think calling the discussion SCUTTLEBUTT and GOSSIP is little hard. Those who really do that are journalists (not all)who make little extra money, while the TN guys who were discussing are quite the opposite. I can't see bad guys behind the messages that have passed, but professionel and serious engineers, who try to learn and understand from this sad event. If the correspondens stays within etics and good manner, I can't see why these guys had to be knocked out like that.
Sorry for having another opinion..

I think it ill-becomes any of us to speculate on the cause of this tragic accident or to follow the equally speculative sequence of events.
and especially the implication of it being a European plane. A few years ago, before I retired, I was in contact with experts in both Boeing and Airbus about lead-free reliability. I was informed that they had a common study group and that much of the avionics used was common to both makers. My interlocutors were the Boeing Director of Environmental Affairs and Senior Scientist of International SHEA
Until (if ever) we have facts about this accident, IMHO, we would be wiser to stop the speculation which really amounts to nothing but SCUTTLEBUTT and GOSSIP.
