Can I ask what you think you would learn from public disclosure of the footage possibly held by the ATSB at this point? While you might believe that you have a grasp of the proximate cause, do you have all the information concerning the operation, supervisory factors, preconditions and latent organisational issues? How about the regulatory environment? Believe me, those are the areas the ATSB will be investigating and until that is done, all evidence they receive or collect is confidential and protected - by law. If a state accident investigator loses the trust of the aviation community, their already difficult job would be considerably harder. Would you have them release a CVR ahead of publication? What if they did and you were a crew member, would you be happy with that?
Diligent professionals will undoubtedly reach their own conclusions based on what is already available in the media, and reflect on how they conduct their business accordingly, as they rightly should. Once the ATSB publish their final report, they may conclude that Safety Recommendations are required based on their findings. At that point, the full picture will emerge for industry to reflect on, adapt and hopefully, prevent a similar event from occurring again.
