It could be like a lens flare / bokeh that rotates with the camera, but that doesn't change the fact that it originated from a flying object. A camera artifact doesn't rule out that the camera was still tracking something, even if the remarks about it "rolling" and maneuvering were off base. Just as you'll see lens flare when you film the sun - the sun is real even though the flare streaks on video are artifacts.
