Is there a part missing or are my eyes cheating on me?
You are right, there is missing a cover. The plane is moved with an "Aircraft Tugs" that calms me. It would not have been so good if we have seen this kind of picture on the runway without the "Aircraft Tugs"
The good point is that the CAF's are all within a short time. So we can expect that there are only some small issues and that the customer want the plane asap.
Holy cow! This (7 test flights) hasn't happened for a while. But like you said, they are all short CAF's in consecutive days. At least we know what's going on with it. (Compared to some frames sitting on the flight line w/o movements, like a boss, for couple of weeks. )
