Thanks for the comment! I am already accepting all the standard spellings they have here at jetpunk. Umlauts do not really matter in the spelling since ä/ö are considered as a/o anyway. But thanks for the input. I thought of putting "amerikabomber" as the clue, but though it might be too much?
Maybe you could accept other spellings of Goring since most of us don't have umlauts on our keyboards. I always knew of him as Goehring for example.
Also the ME264 is not a fighter, it's a long-range bomber. Perhaps the clue "warplane" might be more appropriate.
