Inside JJ Churchill’s engineering factory, the scene is one of controlled commotion as high-technology machine tools turn out parts for diesel generators and aero-engines. The company, based in Market Bosworth, a small town in the English Midlands, was set up in 1937 by Walter Churchill, a pilot-cum-engineer who during the second world war flew Spitfires and Hurricanes from a landing strip next to the plant. The family can trace a link to Winston Churchill.
