Just as an aside and nothing to do with the discussion really. One Thursday evening in the 1980's as we were packing up the Royal Show, we were treated to a magnificent display of aerobatic flying by the JCB helicopter. I never found out who it was nor whether it was "offical", (It was after the show had closed). I did wonder about the proximity of Stoneleigh to the flightpath of Coventry Airport, (which was busier then than now). I also wondered if he retained his licence ( or perhaps he had already lost it, (Like the guy who "buzzed" the tower at Coventry some years later).
Anyone remember?
