Did Yeager really do that? If so he's an honorless bastidge and a war criminal.
You mean the German pilot parachuting over Germany who would then walk through Germany, France -- swim the English Channel -- and then surrender to allied authorities?
Distasteful or not, there's a big difference between surrender (shot down over enemy territority) and evading death and capture to fight again another day (bailing out over friendly territority). On the battlefield it was bad form to shoot prisoners surrendering with their hands up, but I don't think anybody gave much though to shooting the soldier trying to rush back to a secondary defensive position.
And as far as honor is concerned, well, that would just be another big discussion over Nazis vs. "good germans defending the homeland," wars of agression, agressors vs defenders vs civilians, shortening the war vs not shortning the war, stopping the senseless slaughter at any cost so that freedom can return to occupied and oppressed people, fewer through the gates of Auschwitz vs. more... Kinda relative.
