Is evidence in the trial made available to the public or is it all confidentail?
Nothing confidential in this kind of trial .. until the judge estimate that something must be examined behind closed doors (most unlikely) at the request of any partie
CVR (transcript) can be requested and produced in the trial
Actual CVR recording (voice) will be not requested unless it's a VERY good reason (full argumented) by the judge ( one case already in a trial in Canada concerning ATC recording if my memory don't fail
)
