I'm not sure how it ended up on-line, but there's a fascinating short-entry log by a B-17 navigator in World War II posted as a PDF file.
The log covers 1943 and 1944. The writer is stationed in England and taking part in missions over Holland, France and Germany. It runs from the flight crew's journey to England and includes more than 20 missions before the narrator's B-17 is shot down over Holland.
The log ends with a recollection, written later, of the navigator's experiences "escaping and evading" in Holland and France after he bailed-out of the crippled B-17.
I found this fascinating, both as a student of history (mostly I enjoy the stories from history rather than catalogs of fact) and as the nephew of a B-17 navigator. My Uncle, Robert Farrar, was a navigator on B-17s in World War II. He never told us much about his wartime experience. If the scenes described here are some of what Robert saw during his tour of duty, then I guess I'm not surprised.
