----------------------------Original message---------------------------- Greetings, For Jeff and others interested in the background of aerial photographs used during WWII, you might want to get a hold of the book _World War II Photo Intelligence, by Roy M. Stanley II. New York : Scribner, c1981. It is 374 pgs. and heavily illustrated. Very informative for the layperson like me who doesn't have a heavy background in aerial photography, reconnaissance operations, and its use in the military.
