The official USAF records are located at the Historical Research Agency, Montgomery, Alabama. They have the unit records (Far East Air Forces, Fifth Air Force, 4th and 51st Interceptor Wings), development records of the F-86, accident reports, and various studies and reports on the Korean War. The National Archives has microfilm copies of these materials as well as some additional Fifth Air Force files. Material on the development of the Sabre can also be found in Air Force Material Command files at Dayton, Ohio, the Wright Field development records at the Federal Records Center at St. Louis, and North American records in the Boeing archives at Seattle, Washington. The best collection of pilot’s manuals (dash one) is located at the National Air and Space Museum facility at Silver Hill, Maryland. Information on the aces can be found at Air Force Museum at Dayton, Ohio.
There is a variety of material on the subject on the internet, but as with all else on this medium, it is of greatly varied quality that typically lacks support. Nonetheless, valuable materials from the Air Force Museum, Historical Research Agency, and SabreJet Classics can be found here. It also has considerable materials on the aces and items that cannot be found elsewhere from the Communist side, however these should be used with considerable caution.
There is considerable material of a mixed nature in magazines. In addition to extensive wartime material, more recently the flood of popular aviation publications has yielded some articles on the Korean air war. Of these many periodicals I would emphasize three. SabreJet Classics is the organ of the F-86 Sabre Pilots Association that prints interesting and useful first person accounts; the magazine appears on the Internet. Over the years a number of documented articles of value have appeared in what is now known as Air Power History. Wings of Fame, now defunct, was a lavishly illustrated, large format magazine that printed extended articles on aviation history, albeit, without documentation. A four part series by Warren Thompson is in essence a book that gives an excellent, readable, and well-illustrated account of the air war that appeared in the periodical’s first four issues. Larry Davis also published a lengthy, detailed, excellent, and extensively illustrated study of the F-86 in volumes 10 and 11 of that same publication.
There are numerous books that cover the Korean air war. Like much else in aviation history, the focus of most of these is at the basic level of aircraft and flying, with little on analysis or explanation. Very few of these books are documented.
