A Mass Spitfire Fly Pass

I was watching  TV when the tell tale sounds of aircraft alerted me to an amazing fly past .  Living fairly near the Duxford Imperial War Museum means we do get to a lot of the vintage aircraft.  However not very often  in a mass display as seen this afternoon passing my house! I Googled it. This weekend is a Two day Battle of Event to include the mass Spitfire Flypass.
