All three were present after 666 landed.
As for the picture on that article, the second a/c was delivered in 2015 direct to Mildenhall. So can't be the one in that pic, (i'm guessing its 664 at the last Waddo airshow) as Waddington runway certainly wasn't in anything like one piece then. Not that the report is much good having relied on an irritating twitterfeeder
I noticed they removed the old V-bomber dispersals from the end of the runway.
