See the deal is when you're looking at something in the sky all by itself. After a certain point, you really can't tell how big it is because you have nothing to give it perspective. You mean, if you had a kite up there or a guy flying around, on a little experimental airplane? Something to give it perspective, you might be able to tell it's an old movie trick, they do it all the time, it's called Force perspective, they fake, how big it is.
