I thought this was a submarine simulator.
As a sub captain my rule is "never be seen by an airplane." Well I'm bigger than they are, so I can never let them get close enough to identify, much less see insignia, etc. I really don't care if they are bomb carrying seagulls, I'm diving to radar depth and waiting for them to exit visual range.
Therefore I don't care if they got the planes right or not. It has no bearing on the quality of the submarine simulation. What something I will never see looks like is not a concern of mine.
Has anyone checked to see if the Empire State building has the correct number of floors in SH4? That is just as relevant, you know!
