The Spitfire was a great plane, but its real potential wasn't realized until the Spitfire Mk. IX with its dual-stage supercharged Merlin engine. And it was spectacularly fast once the Rolls-Royce Griffon 65 became available in early 1944 on the Spitfire Mk. XIV model.

I'm glad that this dying World War II veteran was able to see the Spitfire fly again one more time.

The airframes designed at that time were well thought out. Every one of them could always use more power to unleash yet, more performance.

In the 60s IIRC, Piper Aircraft married a turbo prop engine to the P51 airframe. Performance was astounding. But their intended market (US military) wanted nothing to do with it.

Today there are a hand full of aircraft sold that essentially use this idea, buyers are smaller countries, not the US.
