Vig,
in "Air Command", Collishaw states that on the 6th july 1917 he got 6 OOCs in one fight (he was actually credited with 1 OOC) and that the communique gave him 1 OOC and 5 Probable OOCs.
the chaz Bowyer Communique just mentions Collishaw amongst a bunch of other RNAS pilots that had made OOC claims.
Now that could just be yet another error (amongst the many) in Air Command, but that's the one I was looking at the other day.
On occasion, I found
Above The Trenches making reference to something in a Communique that doesn't seem to exist - again, that could be yet another error in ATT --aarrgghh - did I just say that?
Hugh Halliday mentioned that sometimes Canadian Air Historical notes taken from communiques in the 30s seem different when compared to the book.
I don't know, it's odd.
