I assume your Aunt would have been born around 1915 which would have made her 30 around 1945, and the Luke photo appears to be of someone in their late twenties( could have joined the RAF around 1933). I wonder whether he went to junior school with Aunt or Gran, or whether his parents lived in one of the other flats above the shops. As you say an impossible task unless a photo with name or dates appear in any family albums. The British Newspaper Library is a good place to look for the Cinema story, which may just report the incident without naming the guilty pilot. Good luck with your search.
