A small hiccup

In the film there is apart where a Spitfire spots the German planes, and then shows the German planes flying by. My issues is that I do not have a German plan to animate with, I haven't built one. I don't want to seriously cut a lot of film or remove any important footage because then I will be building my own story, I want to stick with the original First of the few story line. So I'm going to keep the exterior shot of the German plans flying by.
