It is pretty ridiculous, but it's also interesting to think about how that story and Saint George could be tweaked if the powers that be remade the series.
Toning his theme way down, I mean. Mentioning that he was knighted, giving him a pin like that helmet and vaguely medieval clothing, making Saint George his callsign, making his backstory all speculation on everyone else's part. Maybe fueled by the rumor that he keeps a suit of armor in his tent or room or whatever. Having him call his plane a steed less dramatically. Saving "I am St. George, come to slay all enemies of England!" until a fairly late point, after a long and pitched battle, so you could say fatigue is getting to him.
