If, by "biased", you mean "not inclined to immediately suspect any French institution of skulduggery", then I'm guilty as charged - otherwise I'd say I'm fairly neutral. All I ask is evidence of the supposed dots you are joining.
How else am I supposed to understand what you're getting at?
There is no reason - none - for the BEA to fudge anything here even if they wanted to (the A330 is already a successful airliner, and all the evidence so far suggests that they are throwing everything they can at the investigative process). I ask again, what is it that you think you're "defending" here?
