Thanks to Rob Pincus, I have found a cleaner copy of Colonel John Boyd’s Aerial Attack Study (AAS). It was recreated by Mr. Mark Hart from the declassified 1964 version. The recreation is much easier on the eyes than the reproductions of the original mimeographed edition that are generally available.

Prior to Colonel Boyd’s AAS, fighter combat was viewed by the majority of fighter pilots as an intuitive skill rather than one that could be codified. Some conceptual principles had been developed along with elementary tactics such as the Thach Weave, but Boyd was the one who wrote the definitive book. Only Major General Frederick “Boots” Blesse had preceded Colonel Boyd in writing a book, No Guts No Glory, about jet fighter combat. Major General Blesse’s book wasn’t the exhaustive treatise on the subject that the AAS was.
