John,
You are having a busy day!
Re the Sunderland "oops", there is a video of the same incident here:
YouTube - sunderland fly past
And as I'm sure you know, that's the same day that a Vulcan nearly crashed, when it broke a gear leg, landing in the undershoot, followed by a go-around streaming fuel and a crash-landing at Ohakea. More info here:

Re your current challenge, no idea where it is, but what a fascinating picture. A nice Art Deco control tower, an American officer (Ike?) inspecting a vertically-challenged British Guard of Honour with No. 4 rifles (Army Cadets or the King's Own Hobbits?) and are those Russian officers under the clock?
