Can anyone help by me. I would like to know more about a light aircraft that crashed during take off from a field near Wynols Hill House, Broadwell on 13 November 1918. Who was the pilot? and why was he there?

Apparently, there is a photograph of the crashed plane that names the policeman present as Sgt J. E, Bartlet. in a book called "Coleford : the History of a West Gloucestershire town".
