XCVR technology long implemented in China Eastern. This XCVR with certain software, can detects words that are sensitive to managements.
I do not think the CAAC will review the information on the CVR. Face reason they would rather damage it and sent it back to boeing for the analysis.
They will come up with a story like unlawful interference rather what was speculated previously. Sorry for all. I know this is disappointing but this is how it works in china.
