Witness: Events of the 20th Century: Disaster (1999)

David Frost presents two programmes chronicling notable events of the 20th century. 'Nature's Revenge' chronicles the natural disasters which have plagued the earth over the last hundred years, including hurricanes, mud slides, volcanoes, forest fires and earthquakes. 'Man Made Disasters' features the alternative to natural disasters - man-made ones. These include the Challenger space shuttle, the Chernobyl nuclear catastrophe, Clapham rail crash, Schipol plane crash and Siberian air crash.
