I like many here am more than a little skeptical that the truth will out. The financial consequences are too high, if as I believe, the a/c broke up in the air, the ramifications to airbus and also the french government are enormous.
So against the evidence already collected, and without waiting for data to be analysed, your own brilliant deduction is that the plane broke up in the air. If the data shows something different you will of course say that the analysis is forged. And if the data cannot be recovered, you will say that you were right all along.
The recovery operation has gone to extremes of effort and expense to find why this tragic accident happened, in the hope of avoiding it ever happening again. If a cover-up was required it would have been possible to give up the search after the first or second or third failed attempt. But the recovery team have persisted for nearly two years in order to get to the truth. It has been a superb effort.
Set against all this, your own conjecture at this very late stage is utterly futile and pointless.
