Thanks @Troy Smith. Always useful to check all sources. However, while there's clearly been a lot of work put into compiling it, I think it worth pointing out that there are a good number of errors I've spotted in what I've checked so far (an obvious example being a RNZNVR pilot - listed as RNZVR - whose date of death is wrong) and abbreviations for which there are no explanations - even in the abbreviations list. And the abbreviation 'RNAS' being cited as 'Royal Naval Air Service', which grates enormously...
None of us will ever achieve 100% accuracy, but hopefully when our revised book is published it'll be a good deal easier to read and interpret.
