A formation Spitfire flypast from the Yorkshire Air Show.  Two aircraft from the Battle of Britain Memorial Flight at RAF Coningsby and one from HAC that lives at the Imperial War Museum in Duxford.  It's not often you get to hear three Rolls Royce Merlin engines flying overhead but I can tell you it's a wonderful sound.
