Those who want to make sure it is all on the dead pilots shoulders in a way we don't question anything else.
More read and accept le figaro than scrutinize a BEA report.
Where would go your vote A-B-C-D ... and why ?
From the outset .. I will remove the possibility B
Indeed .. these books are a financial income of Otelli
A change on his part (if discovered) cast discredit on his work and his future as a writer would be seriously compromised
Would he take this risk ?
Remaining possibilities A and C
A = a leak that can only come from someone with direct access to the CVR (BEA- Airbus-AF- or other body accredited with the BEA for this survey)
I think the leak coming from A can be a modified version as the person responsible for this leak is not likely to be discovered easily (I suspect that the leak was not directly transmitted to Otelly .. but instead .. via a journalist .. for benefit of french protection law for journalists sources IMHO)
If Otelli is tortured
for give the name of his source and he give a journalist name .. it's the end of enquiry cause the sources of journalists can't be revealed
The possibility C can be envisaged . .. but unlikely because BEA knowed what was in Otelli book before release of final report (and do not forget the other accredited parties) and because if it's a inquiry about the BEA .. it will be soon discovered if the BEA published a script who does not match the CVR oral recording
This is why I think it's A the most possible option
This option benefit to Airbus principally ....
