In commemoration of the 75th anniversary of Unternehmen Adlerangriff, the German operation to destroy the Royal Air Force in World War II, four Spitfires flew again through the skies of Lincoln.
Some 12 Spitfires took off from Humberside Airport and split into groups to fly over as many villages, towns and cities as the fuel allowed.
On August 13, 1940, the Luftwaffe, an aerial warfare branch of the German Wehrmacht, launched an air strike to try and take out the Royal Air Force, however the operation failed as they were unable to break through British aerial defences.
Had the Germans been successful in their operation, it would have provided them the opportunity to launch an invasion of Great Britain. This became known as the Battle of Britain.
Here are some of the pictures that you took of the commemorative flight:
