Sounds like an engine turbine failure I saw described on another thread.
From what I read, if a fin breaks loose in the turbine, it shatters other turbines in the jet engine, causing massive failure. The shrapnel flying around in the turbine will go through the wing, causing structural failure. That structural failure includes separation of the wing.
The Airbus 300 also has a rather shoddy safety record, and there have been other incidents of these types of accidents. If I can only find that post in that other thread with the links.....
How do you know that the other incidents were accidents. (I have a supercharged tinfoil hat that is actually made out of titanium.)
BTW, other than food and wine, name me one product from France that is considered cutting edge or the best in the world. We know its not electronics or soap, and in my opinion Michellin tires are garbage. Given France's lack of technical innovation and prowess, why would any airline buy and Airbus in the first place?
