Well, it is understandable for a native german speaker. It gives the artwork a funny touch though, as if a the pilots are from the foreign legion, if you know what I mean. It puts a smile on your face, especially the "wir sind betroffen" (that would mean, "it concerns us", but I guess you mean "wir sind getroffen", that would be "we are hit")
So as I said, too, leave it like its is, it has its own charme and fits a comic, but if you do want to have it perfectly straight and clean... your choice, I like it the way it is...
