Goodness, what a wealth of information and load of experience with 'the queen of the skies' here. Makes my 1200 odd hours and only four varients, T4, B2, B15 and 16, look very hum drum, but I have to say, very enjoyable.
But I was very impressed with the site mentioned by Beeayeate, 11 April, with all the variants, and the foriegn users. I was specially interested in the German aircraft, and delighted to see that 9935 is still looking good. After leaving Her Majesties employ I had a couple of enjoyable years flying those aircraft on photo survey and radar calibration flights, out of Cologne/Bonn. In my time we had a couple of English pilots, with German Luftwaffe navigator/photo operators, until eventually ex Luftwaffe pilots took over from us. I notice that I flew D9567 back from Decimommanu on 30Nov76, and flew it again as 9935 on 17Dec67 on radar calibration. Interesting job, and good mates.
