Here is a video that might interest you! its the training film for the B29. http://www.zenoswarbirdvideos.com/B-29.html I also have the crew manual, which is interesting not least for the cartoons that was used. Better than the quotes from Alice in Wonderland used in AP1234, Manual of Navigation used by the RAF.
Lets not forget that postwar, 90 sqdn flew the B29 which was called the Washington in RAF service, as a stop gap untill the arrival of Canberra bombers. Also, 192 sqdn flew three RB50 for Elint duties.
