Also thanks to all.
However, I'm still not clear if Stirling's retained the two pilot set up or also later changed to one pilot and flight engineer, seeing as they had a different crewing arrangement then the other two heavy bombers. Then later of course it was used for towing gliders, perhaps leading to another arrangement. The only pictures I've seen on the internet show two sets of control gear in the cockpit.
