All this speculative talk of prosecution is hardly going to enlighten the average PPL of the navigation and flight planning errors of our hero.
I take it that we have nothing further factual to discuss in the past few pages. There are many useful points on planning and wisdom of choosing to fly in certain airspace that are otherwise lost if we progress with further speculation on old VH's fate.
As we can at least all agree that there is little public interest in prosecuting anyone who certainly had no intent of breaching rules and/or best practice, it is highly probable that the relevant authority will take the same view.
It is also unlikely that our hero will be as open and communicative with the CAA and AAIB if such talk continues - hinderance of any investigation that takes place by such talk is therefore, surely, counterproductive for flight safety.
