Well, I've been doing some thinking, and in all honesty I should have made a thread like this months ago, but I never got to it. Regardless, I'll start. As we know, the P-39 was scorned by many for it's lack of high altitude performance, a dangerous tendancy to spin and a myraid of other problems, but when I decided to take a look at the original design of the airplane, one could actually see a rather interesting design that could have been a top notch airplane in 1941, equal or better than anything else the Axis could have had. The Bell P-39 So here's my question... what if the USAAC didn't mess up the design and kept it as it was intended by Bell? I know that the performance of the production model wouldn't have matched the prototype (the proto had no weapons or armor) but it would have still been very considerable as far as I can see. Well, any answers?
