A great story about the classic war machine. Like the Russian Sturmovic, the P-47, Hawker Typhoon, A1d and other ugly ducklings of the sky, this is one effective tank killer and ground attack machine. One of many legacies of the incomparable John Boyd. The F -16 and F-15 are only as good as they are because of John Boyd and the A-10 exists at all only because of John Boyd. Col. Boyd was the master maneuverer and Pentagon antagonist that managed to save more lives than any other man in the DOD. God bless you John Boyd.
