The Tornado failed with its engine, but that's pretty much beside the point, since there was little need to develop either engine or aircraft, but without Spitfire the need for a Hurricane successor would have been much more pronounced.
It doesn't matter if the a/c in question would have been the Tornado or Typhoon, or some airframe and engine combo that did not see flight, all that does matter is that Hawker would most likely have filled the gap by 1941/42.
So within the
theme of the question, there is no
major error. Besides you twist my words, but whatever makes you tick, right?!
What do you think Nonny? How do you think British fighter development would have progressed without Spitfire?
