Well, I wasn't RP, merely pointing out that both then and in my future scenario the RAF could be flying aircraft unfit for purpose, for whatever reasons. Your aircraft can only be destroyed once whether it be because it is too slow, unable to defend itself, or self destructs with the entry of a small calibre round into its vitals, or entirely on its own unaided.
I take your point that you make, mine is that it would be entirely theoretical if the day is lost anyway.
