Watch Radar - Echoes of the Past

Worth Matravers is today a quiet village near Swanage, South Dorset, UK. But for two years, 1940-1942, when wartime Britain was in its greatest months of peril, Worth was Britain's "Silicon Valley", home to 2,000 scientists and engineers working on one of the greatest secrets of World War II - RADAR. A fascinating story brought to life by site visits and rare original pictures from 75 years ago.
