With just days to go before the Royal wedding, a group of pilots have taken to the skies to rehearse the fly past that will take place on the big day.
Seven aircraft will take part in the formation that will fly over Buckingham Palace at 1,000 feet on Friday, following the marriage of Prince William and Kate Middleton.
A Spitfire, a Hurricane and a Lancaster will leave RAF Coningsby in Lincolnshire and make their way down to London where they will then assume the Battle of Britain Memorial Flight formation.
Thirty seconds later two Tornado planes and two Typhoons will follow in the Windsor formation.
Wing Cdr Dennis, who joined the RAF in 1991, said: "We're a very, very small part but incredibly proud and happy to be part of it.
"This is a great day for the nation that people will remember for a long time and to represent the RAF in an aircraft over the top is absolutely superb."
