Brett Holman. The Next War in the Air: Britain's Fear of the Bomber, 1908-1941. London and New York: Routledge, 2017. Yes, I'm one of those authors, the kind who buys the paperback edition of their own book, just to see what it looks like! At least I'll get some of that back in royalties...
Mike Milln. Wing Tips: The Story of the Royal Aero Club of South Australia. Book I: 1919-1941. Kent Town: Avonmore Books, 2011. This has lots of useful information about the founding of the RACSA and its activities in the interwar period, including the 1936 aerial pageant at Parafield -- which I'd discussed in a conference presentation a few days before I found this book, when it would have come in handy!
