Sorry, I can just tell it from the tanker's view, not from the point of postwar writers who thought that they "knew" something
And that's exactly why the term "kill" disturbs me as it simply does not fit as translation for german "Abschuß" .
I think most ones simply thought they could transfer the Luftwaffe Abschuß recognition system 1:1 to the tankers.
