The author and publishers of the book
Darwin Spitfires have provided a wealth of supplementary material for the reader at the website for the book including 12 appendices, maps, glossaries, pilot biographies, reviews of the book and links to numerous photos from the AWM archives.
This is "how it's done." This is what a website can easily do to support the launch of a book. A professionally designed page that supplements the material in the book, providing more information for the reader. Outstanding. (hopefully it increases sales as well)
Hopefully the website will eventually include a page for
errata as it is identified in the text.
One appendix, "RAAF Air Combats in NWA" clearly charts the numerous claims and losses for both sides. The author uses the description "written off" for a category heading rather than the more familiar expression "shot down". Quite a few Japanese aircraft that engaged in combat over Darwin and sustained damage managed to make the long overseas flight back to their base where their bombers and fighters were "written off". Most or all of the Japanese bomber crews would survive in such cases but their Type 1 bombers would no longer fly combat. They would be relegated to flying as "hacks" or become a source of valuable spare parts for other bombers which needed repairs. Whether a Japanese bomber or fighter was "shot down" or "written off", the Spitfire pilots still eliminated an enemy aircraft from combat though the crew would live to fly another day in the later case.
