James,
As Shakespeare said, Get thee to an Archivery.
Everybody likes to think they can find all the information they want on the Internet. They have no idea how much paper is held by USAF Historical Research Agency at Maxwell AFB in Montgomery, Alabama; and in addition, just in your area of interest, at the National Archives in College Park, Maryland, in Record Group 18.
The WW2 material at Maxwell was microfilmed many years ago, and is currently slowly being copied over to PDFs. You may be able to make arrangements to go there to look at the originals, or the microfilms (I don't know how easy it is for a researcher unknown to them to get on base). You can also use
http://airforcehistoryindex.org/ to do a search of their holdings as of 2001. I never found that easy to use, so read the FAQs for how to obtain a free copy of their index for your computer.
For the National Archives, go to
https://catalog.archives.gov/advancedsearch and put in a Group number in the Search Term field (xxx Fighter Group, or Bomb Group, or Bombardment Group). Put 18 in the Record Group field; and select Textual Materials in the Type of Archival Materials field. Click Search at the bottom, and wait. Their servers are slow. The College Park website itself is
https://www.archives.gov/college-park
If you go to College Park you can copy documents by bringing a flat-bed scanner (never a sheet-fed scanner), or a digital camera, or the camera in your phone. They have camera stands for a camera or a phone, which you can borrow.
Enjoy!
Frank.
