Published in 1945 by the 65th Fighter Wing, Saffron Walden, 8th U.S. Air Force. This document was written to make and show why certain recommendations may help future air force commanders conserve fighters; this is not a training manual, however. It details the fact that flak was by far the most dangerous weapon the strategic fighter had to face. How it all came about and what was done to meet the problem (what was encountered, solution by phases, and lessons learned and recommendations) are told in the report. Please note this a high quality, carefully and extensively cleaned up copy of an archive document and while many efforts have been made to clean up these historic texts there may be occasional blemishes, usually reflecting the age of the documents and the typescript used at the time of writing.
