For people interested in RAAF, particularly in WW2 can I suggest http://www.diggerhistory3.info/raaf/ It is a reproduction of an official book put out by RAAF for their Golden Anniversary. It has some Australian Flying Corps details (1914-1919) and covers RAAF from 1921 to 1971. It has many, many great insights into the debt we owe the Boys in Blue. Cheers, Ted Harris
