There were two occurences at Farnborough shows, the first being a B1 not a B2 back in about '98 I think. In this case ATC advised the pilot he was heading for the wrong airfield but for reasons known only to himself, he didn't respond to heading instructions.
The B52 in'04 was entirely differrent, his turn onto the runway for his run-in coincided with opening the throttles (8 don't forget) to accelerate to his fly-by speed resulting in his overshooting the runway centreline by a considerable margin, inertia of the aircraft was so great it wasn't possible for him to re-position, hence to onlookers he appeared to have found the wrong airfield!
Needless to say, this wasn't repeated, so I don't know where spanishflea got his info.
