Perhaps just be aware that many death certificates for WW2 contain next to no detail (e.g. 'killed in action', 'died from accidental injuries'), and the place of death may be recorded in very general terms (e.g. 'Western Europe').
The service records, though more costly, could be much more informative.
Hello
An RAF Service Record we purchased relating to an Airman killed in an Air Crash at West End, Southampton only says:-
"MBK" [Missing Believed Killed] and date.
"Killed in Action" and same date.
Corner stamped "NE" [Non Effective] also used when sick or injured. Also probably used when leaving the Service.
The £30 was a waste of money, because his Units, his Awards etc., were all recorded on his 4 page Certificate of Discharge, sent to his next of kin (My Grandma) in 1940.
Anyone visiting The National Archives (TNA), Kew to see original documents and files will need to prove who they are and where they live and take this with them, to get a 'Readers Ticket' or renew it. See the 'Visit Us' & 'Readers Ticket' section of their website.
The Cause of Death registered by his Squadron was "Due to War Operations", so Death Certificates often don't say what happened.
