The old argument.
Yes, the Hurricane was critically important. Its numbers gave the RAF the ability to fight a protracted battle, especially the fact that so often it could be put back into service quickly after being damaged.
But the Spitfire gave the RAF the ability to take on the top German fighters on an equal footing, and that mattered a great deal as well.
Each plane found its niche and performed superbly in that niche. Yes, the Spits got the most attention, and the Hurries don’t always get the credit they were due, but that can’t be corrected by simply switching the credit from one side to the other.
I think I read somewhere Dolittle was responsible for getting the fuel into production....guess he made good use of it flying off the carrier to attack Tokyo.
