Also, aircraft cannot "train" at unlicensed airfields. These aircraft are probably flying purely for pleasure.
Just a small point Smithy, I believe microlights are allowed to train from unlicensed fields, unlike Group A, which of course must train from a licensed one. Circuit bashing is often what people complain about...I don't know if this is the case here but I will can see why that could become irritating if you did indeed live 300yds from the runway.
