If it's in the air, it must be flying, no? (there are too many pictures in diff. locations to say photoshop) Without any technical specs on it, I'd guess counterweights? Your guess is as good as mine on this one.
Just because there are pics of it in different locations, doesn’t mean that is a real object, no? I shouldn’t be sarcastic. Afterall, maybe where you come from they might not have the photoshop experts to pull this off. There was a first ship and now there is another one that is similar. Also, you might not have caught that someone pointed out that the writing on the underside resembled Japanese. I agree.
