The sound of the Merlin engine roared over Duxford this weekend to commemorate 75 years since the Battle of Britain.

Eighteen Spitfires took to the sky above the Imperial War Museum to represent the Duxford Big Wing, a fighter tactic developed by Douglas Bader and Air Vice Marshal Trafford Leigh-Mallory, in a fitting finale to the sell-out event on Saturday.

The iconic plane also performed a flypast with a Eurofighter Typhoon, as well as two F-15E Strike Eagles.

A Hawker Hurricane also joined a Spitfire to intercept two Hispano Buchon aircraft and a Messerschmitt Bf 108, which triggered the airfield’s air raid siren.

A number of other 1930s air craft which were flown by the RAF at the outbreak of the Second World War were also part of the weekend’s displays, including a rare Hawker Nimrod and a de Havilland Tiger Moth.

Three North American Harvard aircraft, a Calidus Autgyro, a Slingsby Kirby Kite, a Slingsby Petrel and a Piper Super Cub also flew for the thousands of visitors.

The Red Arrows completed the line up for the show.
