Re: NA (PRO) trying to make all its digitized collections free to access (Now ACTIVE)
Combat Reports for WWII are available, but it looks like individually, rather than the whole file, unfortunately.
That said, I was able to download bulk Combat Reports for 41 Sqn for WWI (AIR 1) FOC as well. There were four files covering the whole of 41 Sqn's war.
Shame that files such as AIR 79 are not available, but that's understandable considering it's an income stream for one of the genealogy sites, so they wouldn't want to undermine it. However, I had hoped that Station, Wing, Group and Command ORBs might have been available, too, and some of the WWI Officer files in WO. I note that WWI British Army War Diaries are also available, but it appears that those for WWI RFC/RAF units are not - though happy to be corrected.
41 (F) Squadron RAF at War and Peace, April 1916-March 1946
