I have often read that our (USAAF) pilots deplored using the P 39 against enemy fighters in the European and North African theatres. I have also heard that on the flight debut (of the P 39) with the British, the plane was immediately given a bad reputation, leading to only one squadron being equipped with the fighter. What made the P 39 so bad in running dogfights? I am aware of the lack of supercharger, but were there other limitations in the design? On top of all of this, how were the Russians able to use the fighter (not to meant be condescending in any way) and have pilots enjoy the aircraft and request it?
