That would be rather a neat trick, since (so far as I understand it) the Mighty Eighth was a re-designation (in Feb '44) of VIII Bomber Command, which itself wasn't constituted until Jan '42, after the declaration of war in December '41.
I see the thread mentions 1942 - just crossed dates re: declaration of war? (A date which will live in infamy...)
Edit - Good info here:
