Bud Anderson is an absolute legend. Owns his old mustang too. Still flies Old Crow as far as I know.
Chuck Yeager is quite rightly a great man, but his ego is a match to his status. Which while polite (I met him briefly at the Avalon International Airshow), you can tell an arrogant SOB when you see one, mind you he has every right to be considering his achievements. "A great man is seldom ever a good one"
Robin Old's however in my opinion is the finest American air combat leader that has ever been. In touch with his men, fights with them, and never puts their assses on the line unless he was there too.
