Hi Grünherz,
>As for altitude the chart I have shows 435mph at 30K, I dont think there are any better planes than that till 1945..
Well, I haven't seen the report so I can't really comment on it. Still, I'd be suprised if the final production aircraft would have been significantly superior to the Fw 190D-9.
