P-63 in Pokryshkin's squadron

[Josh Osborne]

I haven't had time to check the sources in the article, perhaps they are completely bogus. I admit that identification by spotting flying aircraft, rather than inspecting wrecks, is a very unreliable way to identify a type. I am not sure if this idea is just another internet hoax, like the idea that the p-38 can outdive a p-47 if it has dive flaps. This is the first time I have seen the "p-63 on the eastern front" in a respectable place (I assume Wikipedia is reliable?), so now I wonder if there is some truth to it.
