With respect, and in respect to the CVR, I think you are missing the point. You want to know what happened, you want to know who said what, when and to whom. Fine. May I suggest that you just ask them, bearing in mind that every conversation has at least two witnesses available to you ? In what circumstances do you think you would need to pull the CVR in this case? If you need to understand why 250 bodies are lying on the ocean floor ok, but in this pathetic example of US cultural goat f+ck?
