Days that Shocked the World explores the most iconic disasters of the last 50 years, combining eye-witness testimony with powerful archive footage, to learn how each tragedy changed both the lives of individuals and the world. The anthology series features one- and two-part episodes that coincide with key anniversaries of these defining global events: including the Challenger Space Shuttle explosion in 1986, the Chernobyl nuclear disaster of the same year, the 2000 Air France Concorde crash, the 9/11 terrorist attacks in 2001 and the 2011 Fukushima earthquake and tsunami.
