E-G,2 starting points; Was there any mention of any particular year that this happened ?If so there maybe records in the local `rag` archives.Likewise,I would have expected him to have `reported` to the local Constabubble`,so he could report a downed aircraft to the nearest RAF unit to provide guards etc,assuming that he had an armed aircraft/Verey pistol/personal weapons etc...You can`t just leave an aircraft lying about,and as he seems to have been `mobile`,then suggests it was more of a forced landing,rather than crash,ie with injuries.
