I wonder if the silence indicates that all is not well in that regard?
The silence from the French investigation team is easily explained by the fact that at this time of year, the French as a whole, take their annual 4 or 5 weeks vacations, and head for the coast. I'm sure that in the fullness of time, all will be revealed.
Let's not forget, amongst all the wild theories of "other scrap B777 components" being the source of the flaperon - that a total of 1320 B777's (all variants) have been built to July 2015, and only 5 hull losses have been incurred by this model.
1265 B777's are currently in regular use by airlines, the remaining numbers can be tracked down and identified, and are either in storage, or in the process of sale, or undergoing maintenance/repair.
Of the 5 B777 hull losses, only 1 hasn't been recovered. That hull is MH370.
For a flaperon from the other 4 B777 hulls lost, to show up on the shores of Reunion Island, is about as likely as your chances of winning 1st prize in the EuroMillions lottery - particularly when MH370 disappeared in the Eastern part of the Indian Ocean, and flotsam from that area regularly washes up on Reunion.
