The F7F, F8F, Horten IX, Pfeil, Tempest, P80, Ta152 and 190D11+, P51H, F4U4, La9, Sea Fury, etc, are the pinnacle of WWII warbird design. Performance claims were outrageous for the F7F? Is that surprising? Didn't Widewing correct you on that, last time around? Why isn't the F8F surprising; or do you deny its performance too, just because it was late to action by a couple of days ?
The Ta152 is a late war design, tho unfinished.. Is that one dismissable too? There's a difference between off the wall VTOL UFOs with guided missiles and the F7F.
