You would have thought they would be an asset for the airshow as the RAF are normally pitiful these days at displaying anything... I went to Cosford a couple of years ago and that started with a "flyby" down the runway of the fire section vehicles followed by the medical section vehicles followed by the Padre... I thought then, yup, they are desperate for anything to display, and it turned out to be the case... It was pitiful and embarrasing.
