It seems strange why the CVR and FDR data not yet published. All the speculations will be exhausted if this data will come public.
If the FDR data will be converted to be an animation and this animation is accompanied by the CVR audio recording, so the overall situation provides a clear picture of what really has happened.
CVR and FDR are installed in the helicopter just in the cause of the accident can be quickly and reliably verified.
What’s wrong?
