A number of people appear to be beginning to question the design choices of the Airbus engineers, apparently on the basis of looking at a few small pictures on the internet.
For the same reason that we would hesitate to start shouting "pilot error" so soon after an accident, let's not start a witch hunt for the engineers until we know a lot more of the facts.
It may turn out that it is down to a design flaw, or something to do with the little known effects of temperature/pressure cycles on composite materials over long periods. One thing is fairly certain: I doubt they would have made such an obvious error as to have made the attachment lugs too small or weak.
In the meantime, a little bit less of the hyperbole please - you don't like it when people do it to you!
