Could anyone kindly advise me as to where I could obtain details of the service and fate of a Polish Sargeant pilot OLEK ALEKSANDER who was shot down and killed around 1943 in Britain.I have,surprisingly , inherited many letters and photos/insignia of the pilot who was friendly with my mother who lived at Kenley in WW2. I have interesting photos of this man in his spitfire ,with General Sikorsky etc and am keen to return his letters and photos to his family.This is possible since,ironically, I have married a Polish national and travel there intermittently! I would be grateful for advice on where to get Polish pilot war records from this period.Thank you in advance.Robin Sanderson
