It would seem like there's a lot of hand wringing going on behind closed doors on how to deal with the outcome of the AAIB investigation?
The owner of the aircraft would seem to have admitted 'some liability' according to newspaper reports?
That MAY indicate a particular conclusion to the inquiry which means that some sort of legal proceedings may be in the offing.
If so, how this is all announced to the World in general would potentially affect any legal proceedings?
