I agree with what Don said about Bart's winning flights at the 67 Nats. There definitely were no better flights than his at that Nats. And I have seen very few flights since that match what Bart did that summer.
He had the right shapes, the right sizes, blinding corners, great intersections, great bottoms, everything there. And it was "smooth" and it "flowed". He also did what few have been able to perfect, he made it look easy.
After 39 years, Bart has not lost much of that talent. A good airplane, some practice and a coach, I do not doubt that Bart could be in contention at any level.
