It takes a lot of hard graft and dedication to keep the old warbirds at IWM Duxford airworthy.

The historic airfield's latest themed flying day took ticket holders behind the scenes at the Cambridgeshire site.

Duxford’s home to Spitfires, over 100 years of history, and some of the best aviation partners in the business were all celebrated at Saturday's sold-out event.

The event recognised the important work everyone onsite at IWM Duxford does to keep audiences entertained and iconic aircraft preserved for future generations to enjoy.

Visitors to Europe’s largest air museum were able to see Supermarine Spitfires in the air.

Before then, IWM Duxford will host the Duxford Summer Air Show on Saturday, July 24 and Sunday, July 25, featuring the RAF Red Arrows.
