It's an interesting one but will have to wait and see, at least they found the thing this time, they were refused a climb to avoid bad weather but that shouldn't bring down an Airbus.
I quote "In the A320 family, accidents and incidents range from fan-cowl detachment, landing gear collapse, bird strikes right through to hull-losses through pilot error. Most aircraft have teething problems and in most cases these are eradicated. Very rarely, these issues cause disasters -- largely because of a culmination of factors that lead to the event."
It's the same with AFR447, not one single event brought down this aircraft out of the sky. But this seems a very sudden incident.
