Duh! You think so?

It could be just that Nazis are not very good team players. Sure there are bullets coming in through the cabin. Sure someone has to drive the plane around the sky. Sure someone else has to travel around backwards all the time. But, can't these two realise they're on the same team - despite how sick and twisted the ideology that brought them together? And here's the problem, teamwork or a lack of it tends to be self serving. It doesn't necessarily allow team members to look beyond the task at hand. So it's great for getting things done but not necessarily good at differentiating between right and wrong. So possibly it might be a good thing to shoot at sky Nazis, so that they might begin to question themselves. That can only be a good idea.
