The Channel Tunnel linking Britain with France is one of the seven wonders of the modern world but what did it take to build the longest undersea tunnel ever constructed? We hear from the men and women, who built this engineering marvel. Massive tunnel boring machines gnawed their way through rock and chalk, digging not one tunnel but three; two rail tunnels and a service tunnel.
