Being up here in the Niagara Falls area, I see our P39 in the museum often (Bell Aerospace was up here during and after WW2), and I think it would be a great add on to AH.
The original plane had a serious turbocharger that was later taken out, but the plane was still used (4700+ of them) by the Soviets as a low level and anti gv plane. The whole reason for the engine behind the cockpit was to fit the large 37mm in the nose of the plane to fire out of the propeller hub.
I know it isn't a popular plane..but think it would be a nice alternative to planes like the IL2 for defense against gv's.
