There wasn't much clearance (five feet each side?) between the wingtips and the brickwork!
Buy the film (The Blue Max) or the book (Delta Papa by Derek Piggott). Neither will disappoint you, especially the film if you like Ursula Andress!
PS, Double Zero, do a PPRuNe search on Hunter and Tower Bridge within the AH&S forum for more gen on that episode. Well worth it for some authoritative opinion!
