Only if the search is called off and BEA presents a slippery conclusion will the conspiracy theories begin. I, for one, can't see that happening.
Me neither.
They wouldn't be that stupid....
Moreover, the uncertainty about what happened cannot be in the interest of Airbus either.
It implies there is an unresolved risk of an Airbus plane to be knocked out of the sky.
Only if they know (and everyone knows that they know) what happened they can credibly make sure and also clear to the public that it won't happen again.
As long as the real cause remains somehow unclear they can't make this claim...
So there must be also a vested interest of AI to find the recorders as well.
