Radio Operator's Information File KC-135 and P-47 ThunderboltThis is an original WWII era Radio Operator's Information File published in 1944 (updated 1945) by the US Army Air Force. It is the basic reference book for aircraft radio operators in the performance of their duties. See photos. The page numbers are by section, so total pages are not estimated here. It is about 1 2 inch thick. All pages are intact as is the soft cover. It is in exceptional condition given its age.
