text: If you know the name of deceased aircrew then the Commonwealth War Graves Commission site is _the_ definitive source of information since all deceased aircrew are on their lists.  The records will show, the airman's service details e.g., aircrew category, service number, squadron on which when KIA,  home country (often the parents' or wife's name and address), etc. plus the date of death. \n\nFor really thorough details the only way is to visit the Public Record Office, Kew, London and look through microfiche copies of Squadron, Station, Group and Command Operations Record Books (ORBs). These will give details of the crew, their positions, date of operation, target, ordnance carried, crew debriefing or if 'missing in action', etc..  You can also read actual Combat Reports written by fighter pilots and bomber air gunners. There are also bravery award details with copies of 'citations'.\n[ NB To examine all these things personally is free - all you need is a Readers Ticket. Issued on production of some form of ID such as your passport. ] \n\nIf you would like to sit at leisure and read about WW2 aircrew casualties then go to your local library and ask to see the series of books written by W Chorley (and old acquaintance of mine), called  'Bomber Command Casualties in World War 2'.  He has produced a volume per year and brief details of all casualties are recorded by date of operations.
