I suppose this properly belongs on the History and Nostalgia section, but scheduled for late April is a Channel 4 documentary on the Dambusters, accompanied by a book. Part of it features Ray Grayston who was Les Knight's flight engineer on N for Nan and at age 84 is one of the very few remaining alive of the original 617. Apparently, he has been very reluctant to talk about it up till now, but has been persuaded to 'open up' a little bit. One of the interesting facts he has already divulged is that the Lanc didn't fly at all well with that bomb sticking out. Should make fascinating viewing ... if they show it under the current circumstances.
