Steve, what an opportunity!
I suppose I want to know about the work of the Nav. in the RAF Boston. Much has been written (and read by me) about night heavy bombers in the RAF, the problems of finding the target, pathfinders etc, but I am ignorant of how the Boston (and other day bombers) worked. Altitude for cruise to target, bombing heights etc etc.
Noyade, thanks for that diagram, makes it very clear.
Icare9, sadly I don't really know any more.
