It was more to do with the estimated performance of the aircraft for the Hunter, not year of introduction as it was inside of the games cut-off date anyway. Until we managed to get all of the required details on it, its flight performance was what was holding it back. Im well aware of the work that went into that aircraft, as it was me visiting many museums for photos and documentations on it.
I would ask once again to keep things on topic and not derailing to subjects that have nothing to do with the major at hand.
