"It's just like being in a knife fight in a dirt-floor bar. If you want to fix a fella, the best way to do it is to get behind him and stick him in the back. It's the same in an air fight. If you want to kill that guy, the best thing to do is get around behind him where he can't see you . . . . and shoot him.": Captain William O'Brian, 357th Fighter Group, USAAF."A squadron commander who sits in his tent and gives orders and does not fly, though he may have the brains of Soloman, will never get the results that a man will, who, day in and day out, leads his patrols over the line and infuses into his pilots the 'espirit de corps.'": Brigadier General William 'Billy' Mitchell, USAS.
