Hi ZRX61,
If an RAF officer he will appear in the RAF Air Force List and the On Line London Gazette.
A check of the Commonwealth War Graves Commission web site will tell you if he was a casualty of war.
PoW lists will say if he was captured.
If he survived the war the RAF Retired Lists will say when he left the service.
The Confidential RAF Air Force List will give his postings.
Post his name and service number when you have it, I may be able to short cut your research task.
Regards
Ross
