I can recommend 'Royal Air Force Bomber Command Losses of the Second World War' in 6 volumes by W.R. Chorley published by Midland Counties Publications, 24 The Hollow, Earl Shilton, Leicester LE9 7NA. ISBN 0 904597 87 3. Each a/c lost is listed with serial no. squadron, base, take off time on last trip with various available notes plus entire crew and force e.g. RAF, RAFVR, RAAF, RNZAF, RCAF, Netherlands, Poland, Free French etc. A surprising number of neutral Yanks served as 'Americans' (they were RAFVR) but, many, many, more served as RCAF. Many transfered to the USAAF post Pearl Harbour but many elected to stay with 'us'. Some of those who transfered elected to continue their 'tour' with the RAF wearing American uniforms, new upgraded ranks, there were no NCO flight crews in the USAAF, and of course the extra pay. Statistically, the RNZAF lost more men per volunteers than any other 'Empire' crews. There is also a Fighter Command Losses book in this series. Cheers from Eng! land Anthony Loates
