Being ex RAF I had the pleasure of seeing these close up when I was at RAF Cottesmore in Rutland as it was then. We used to get 4 of these there on exercise for a week at a time along with 6 Lightning fighters, they used to make a wonderful noise when they were all scrambled at the same time. But must admit that the sound of a Rolls Royce Merlin in a Spitfire takes some beating, just got to love that sound.
