How Do They Do It?

The programme explores the construction process of wrecker trucks, detailing the engineering, component fabrication and assembly steps involved. It also examines how Roquefort cheese is produced, tracing the traditional methods, and follows the techniques used to transport trees safely across distances.

The episode titled Wrecker Trucks/Roquefort/Tree Moving is a programme‑type broadcast that presents a series of specialised topics in a single instalment. It is structured as a concise, factual look at three distinct areas of industry and logistics, offering viewers a straightforward glimpse into each process. In this instalment the audience is taken through three separate features. First, the construction of wrecker trucks is examined, showing the steps involved in assembling these heavy‑duty vehicles. The second segment turns to the making of Roquefort, outlining how the cheese is produced. Finally, the programme follows the methods used to move trees from one location to another. The portion on wrecker trucks focuses on the engineering and manufacturing stages, highlighting the components that give the vehicles their strength and capability. It walks the viewer through the assembly line, illustrating how each part fits together to create a functional recovery vehicle. The remaining sections detail the traditional processes behind Roquefort production and the logistical considerations of transporting mature trees. Both parts maintain a clear, observational tone, presenting the essential steps without adding extraneous commentary. Together, these segments provide a compact yet informative overview of three varied yet intriguing industrial practices.
