Thanks for posting...eh,eh...who knows, that could be one of the myriads of green/grey/dark brown aliens going in circles to study us from above...or not...eh,eh...
Actually, I think that if it were an alien spacecraft, NASA would have told us no news at all about it, as the Space Agency had done for so long about such things it had already discovered a lot about, without informing the population, of course, since many years ago...usually, when such news come out it's just to demonstrate to the public that alien spacerafts are fictional and that could turn out to be only a piece of some human old spacecraft orbiting outside atmosphere, indeed...
Anyway, who knows...?Maybe it's only something that- this time- is out of their schemes or their (secret...) :-?knowledge...eh,eh...
We'll see...maybe...
As said in X- Files..."The Truth is out there"...eh,eh..but, maybe, also "Inside (some room) here",...eh,eh...somewhere...
