I also had a great opportunity seeing this beautifully shaped aircraft doing these slow climbing turns, in an Air Fair in South America many years a go.
Besides, I can say that I was lucky to see it flying three times, and I kept vivid in my memory the roaring sound produced by its engines, and the gracious manoeuvres performed by this aircraft.
This is preserving history, and would be a live example of an early generation aircraft from a gone era, worth’s every effort to achieve it .
Safe Flying to all
