Icons - Season 1 Episode 2 -

The second in series charts the story of exploration in the 20th century. 20th-century exploration began with flag planting in the name of empire, and over the decades, improvements in technology saw explorers take on greater and greater challenges - pursuing prizes from the poles, to the highest points on earth - and beyond. The incredible individuals who took humankind to the limits of what was thought possible also oversaw an evolution - as time went on exploration went from a tool of empire, to one of cultural discovery and conservation. The story of exploration in the 20th century is one that took us from conquest to understanding.
