I must disagree with Kurt, it might be almost the same like the PT, but is that a problem?
There are several aircraft in Aces High which share similar look, armament and performance, although they are from different countries.
Or what about the B-17 and the B-24? Besides the looks and a small difference in speed, they're almost completely the same!
And from the same country!
IMO that the E-boot would be a great addition
