This is the grave of Michael John Hayman, who died on 14 September 1963 at the age of 19. I did try and find out more about him, but haven’t been very successful. I made a mistake here as I looked up how many war graves were at the church and CWGC noted that there was just one, which I assumed was this. I had forgotten that they don’t list graves that are from after 1947, so I only took this photo.
The incident wasn’t directly related to the military, but as he was a senior aircraftman in the RAF, he was given a war grave. I don’t know why this church was chosen, but it was very close to RAF Filton which has now closed, but the site is used by Aerospace Bristol.
