Standardization Handbook for B-17 Pilots, US Second Air Force 1944
Here is an original WWII-era Standardization Handbook for B-17 Pilots by the Second Air Force, September 1944. This 5x7 inch booklet describes standard preflight and flight operating procedures in effect at the time of its publication.
The handbook is in good shape for its age. The cover shows some watermarks but the pages are complete and intact.
