Tail of Airbus A330 made out of composite material like plastic. It is not durable as aluminum, simple crack may cause it to broke off in harsh turbulence. It happen once before in New York. Air France try to hide it now, they occupy all families of victims with their lawyers ( ), families will get close to nothing, but main think no investigation will be made other then Air France ones. It's sad that other people now in great danger of flying those airplanes from Airbus. Airbus French based company, probably owned by same people as Air France. Euros rules, isn't they? How many more people have to die?
