In response to "MaxD", I'm just getting my head around interpreting this kind of document, bear with me. I've attached a screen capture of the most critical part of my Dad's records I obtained. Perhaps you can comment. (I hope I have attached the image properly! Old man, not too tech savvy!) I can see that Dad spent a fair bit of time in and out of the hospital in Aden! Probably accounts for some of the stories he told me regarding dysentry!
As far as the comment by "rafcommands", I did a preliminary looksee at the records available on the National Archives, noting that it will likely take some experience to figure out how to find anything relevant on there. For instance, I can see my Dad was in the 8th Squadron, but when I put that in, there's lots come up, but it's not the 8th Squadron. I guess I'll have to keep visiting that site, trying various things to find what I need. I will be creating a timeline, trying to fill in details, whether they're specific to my Dad or to the Squadron, that remains to be seen. And I can readily see whether he changed Squadrons during the course of the war. No others are evident to me, but as a novice, I might be missing things.

p.s. I have tried attaching an image of the relevant part of the document, with no success. It keeps telling me my message is too big. I've done all within my limited abilities so far. I'm open to any tech advice as far as doing this task.
