In hangars and machine shops the length and breadth of Britain a brave bunch of engineers and aviators endeavour to keep the UK's most historic warplanes in the air.
Fighting a desperate rear-guard action against corrosion and metal fatigue are the engineers. Their only weapons are skill, ingenuity and tens of thousands of pounds. We follow the painstaking work in recreating long-forgotten components from lumps of aluminium, show ancient engines bursting into life again after decades of silence, and watch as pilots roar down the runway for the first take-off in years or even decades.
Each show follows the restoration of an iconic plane, telling the stories of the men who flew it; the part it played in military history; and the challenges it now presents its restorers and pilots.
