Spitfires were the nemesis of the Luftwaffe and the instrument which halted Hitler’s plans for invasion. After relentless bombing of the Spitfire factories in Southampton, the Germans were convinced they had halted the production of the Spitfires for good. But across the South of England, hidden in sheds, garages, back gardens, bedrooms, a bus depot, and even a hotel, a workforce of unskilled young girls, boys, women, elderly men, and a handful of engineers secretly built thousands of Spitfires to help win the war. Witnesses recount this never-before-told story of amazing achievement.
