This is a wishlist, why bother arguing?
We are a small portion of the player base who, thinking we have more influence than we do, like to tell HTC what we think the priorities should be. In my case, I think the P-43 shouldn't even be mentioned until a great number of other aircraft have been added. In some other cases, apparently, the players think our great dearth of American aircraft needs to be addressed before anything non-American is added.
-1 for both due to the fact neither are particularly special or great.
+1 for PBY-5A that would be special unique and could be used as medium bomber and torpedo bomber.
If you were asking for a flying boat that would be useful in the MA I could understand your request, but the PBY-5 would bring no more than the Sunderland or Emily and be far, far less usable.
Ki-43, Pe-2, Beaufighter, Wellington and He111 were all produced in mass numbers and, the Ki-43 in particular and in my opinion, ought to have been added to AH long ago. Fighter vs Fighter performance being a far more significant aspect of AH than Bomber vs Bomber performance.
