Despite what Johnny Johnson opines about the impact of the Spitfire Mk IX, the only advantage this later mark had on the Mark V was on the vertical...

So Mk IXs redressed the balance with their superior climb rate, not superior turn rate...

Gray out, black out, same thing.

OK, so IX wasnt any faster than V?

I dont think you have read the book.... Just another example of turning a vets words to what you want to hear instead of what he says. And not first time of you.
