As I am intending to play a few Bag the Hun games soon I decided to do a bit of reading on WW2 air combat and borrowed a book from the library called "Whispering Death" by Mark Johnston.
The book is about the RAAF airmen of WW2 in the Pacific, but also covers a bit of history leading up to start of the Pacific war too.
I am still in the process of reading it, but what I have read so far is very interesting; I was amazed to learn that by the end of the war, Australia had the fourth largest air force in the world, only surpassed by the UK, the US and USSR.
It is staggering to learn this fact, especially as almost every set of air combat wargame rules hardly even mentions the RAAF. CY6! does have a scenario in the main rule book with RAAF vs Vichy French forces, but that is the only one I can think of.
If I had the time and ability, I would love to 'knock' together a scenario/source book covering the RAAF for WW2. It would most likely be just for myself though as, judging by the lacklustre mention in rules, the RAAF might not be 'sexy' enough for most wargamers.
