Northbeach. While I do not disagree with you on your brillant analysis of the world we live in , there is a new factor coming in : the small black thing everyone now carries in his pocket that can not only take photos , but also record anything discretely and e-mail it to the outside in seconds. That is changing drastically the picture and keeping somethiing confidential today is becoming a serious challenge.
On this perticular topic a few days ago, a book ( in French ) by JP Otelli ( a well known French Aviation author) has released the (almost) AF447 full CVR . I suspect the UK article linked in this thread is based on that book.
The transcript in the book has also the audio warnings added, and that is interesting.
