The symbol is banned in Germany yes but not apparently in the case of education and art I'm doubtful that AH would be banned in Germany if its planes displayed a swastika. I've seen pictures from the Luftwaffe museum in Germany the planes still have the swastika on the tail. There was a recent attempt to get it banned across Europe because somehow they believe a stupid looking cross has the power to build a surge of far right support in Europe and that the problem has nothing to do with immigration policys.
Aces High is entertainment, not education and the Nazi swastika would get the game banned. The Finnish Von Rossen cross, on the other hand, is fine as it has nothing to do with the Nazi's, other than a possible link at the origin point.
The Finnish Air Force adopted the Von Rossen cross as its symbol after a Swedish nobleman, Duke Von Rossen if I recall correctly, donated the first aircraft to Finland to form their air force. A certain German ace, who was employed as a commercial pilot, apparently paid frequent visits to the Von Rossen residence when he stopped in Sweden, being apparently interested a young lady. That German ace was Hermann Goering and he may have remembered the Von Rossen cross and modified it a bit by canting it on its corner and changing colors for the Nazi party.
The basic swastika form is quite common, particularly in India where it is a symbol of good fortune.
