i'm reading a book along those lines, called on half a wing, 3 engines and a prayer. about the 303rd hells angels. one officer wrote in his diary after the first schweinfurt raid, where they were pretty well mauled by flak and fighters, that it was, in his words, a real shaky do. one guy who was a tail gunner said that over the channel he would get himself good and mad, really angry, because it served him better to concentrate, and keep from thinking about what they were getting into, and getting scared.
