PS. Yes the Vulture engines were Rolls-Royce, and my vote for worst aircraft of the war goes to the Vought Vindicator - the last plane I would procure for my airforce if I had to cover all the necessary wartime roles. There is nothing the Vindicator does well that nothing else does better. For the same reason, the Brewster Buffalo is my second vote. It's success in Finland was largely due to the poor Russian training and equipment in the early-war stages, and the plane is hideously over-modelled in FB.
