The Spitfire was nice, but the Hurricane was the plane that fought the majority of Battle of Britain. The Spitfire had a flaw with the canopy being sunk flush with teh back of teh plane, which lead to angle of attack advantages to the German’s, it was teh same issue with teh P-40, which lead to the bubble canopy’s of the later fighters rolled out like the P-51 and the later models of the Spitfire to correct that problem.
The Brits would have been wiped out if the German luftwaffe would have used more commen sense with the blitz on bombing Berlin. It was the decision to not increase fuel capacity on the Me109’s that lead to the bombers being easy targets for teh Hurricanes and Spitfires. Overall though the Spitfire was teh model for teh P-51, without looking it up didn’t we use the engine for it on the Mustang?
