FlyBoy, your head is up your arse and you do the aviation industry a severe injustice if you can seriously believe that any manufacturers, regulatory authorities and accident investigation bodies do not want to find the 'black boxes' after this or any such accident. The only reserve that may well understandably be shown is to avoid feeding ignorant journalists, who have no interest in safety, of any information that will inevitably end up being distorted and sensationalised.
