You people are running an irrelevant argument. The P-63 is one of the last plane this game needs even if it is found to qualify HTC's requirements. Even when it is finally added, it is a perk material if there ever was one. In other words, a waste of HTC resources.
There is a long list of planes to be added that are much more historically significant, plug holes in the plane set, will not require a perk tag and prevent AH from turning into a "summer of 45" game. The wish is perfectly legit, but the chances of getting it are nil.
