Good thought! The 'Millennium Falcon'-ish formation in the Black Sea is about 197 feet in diameter (I just looked that up). Curiously enough, according to the Wookieepedia ( [link to starwars.wikia.com] that's about twice the size of the actual ship.

But Google Maps shows this thing to be half the size as the Black Sea anomaly, and almost exactly the same 25.61 meters (84 feet) width as the 'Falcon'.

But it doesn't look exactly like the 'Falcon', at least not from space, and from whenever this picture was taken...

BUT... (Hmmmm...) A lot of the original Star Wars was shot in Tunisia, and the landscape here is arguably quite Tatooine-ish... Perhaps we're seeing the beginning work on the recently-announced Star Wars 7 sets?

I wish I knew...
