How right you are! When I first saw this article, I had never heard of the man. So I've been poking around the 'Net and finding out more about Col. Boyd. As I have done so, my estimation of this remarkable American has grown exponentially.
I strongly recommend that you find out more about Col. John R. Boyd. Among other things, you'll discover that his "Energy-Maneuverability Theory" was used not only in the design of the F-16 (which rightly or wrongly you disparage) but also the F-15, which you so rightly praise.
But I am coming to believe that his greatest contributions to America have much less to do with aircraft design or air combat tactics per se than military strategy as a whole.
It has only taken me a few hours of study to conclude with confidence that Colonel John R. Boyd was, beyond all doubt, a military genius of tremendous historical significance.
