Battle of Britain: Prince Harry meets flypast crews
The biggest flypast of Hurricanes and Spitfires since the Battle of Britain is due to take place on Tuesday afternoon.
Wing Commander Tom Neil, now 95, who flew 141 combat missions during the battle, is due to take to the skies.
Prince Harry was due to fly a two-seater spitfire, but the BBC's Robert Hall says the aircraft has become unserviceable.
The Prince has given up his place to enable Battle of Britain veteran Tom Neil and two wounded servicemen to fly.
Duncan Kennedy reports from Goodwood in West Sussex.
