Yes, these documents can be purchased in hardcover form (or are available freely if in the US Military as a library checkout) or downloaded under the Freedom of Information Act.
These actual volumes comprise the ONLY entire record of the Air Force during the war. They make for facinating reading to say the least, and as they are directly from the source, they have a lot of detailed information including a lot of information between command level staff that is not really available anywhere else in the world.
There are some issues with accuracy that may be corrected in other sources, but nowhere will you find the actual guts down to this kind of level. It is pretty much a 7000 page history of the Air Force in WW II detailing who was who and why things happened the way they did.
Any works that are not the property of the government do not have the actual PDF form available as they would obviously be subject to the copyright holder. Sorry if I seemed grumpy, but your note caught me in a "bad day at the office" mood
As a side note, they have fantastic maps and recon photos of bases actually taken at the time which really help putting a scale on things that you do not get playing the game. Well worth the hours it takes to pull down the 7 book set of WWII.
