Join us for a devastating but enlightening hour as we delve into complex and often-tragic engineering failures that have shaped our world. Five dramatic events unfold as we discover the causes of: the 1983 collapse of New England’s Mianus Bridge; the sinking of the EM Ocean Ranger /EM offshore oilrig in 1982; the crash of a Learjet 35 private plane carrying pro-golfer Payne Stewart in 1999; the 19th-century failure of South Fork Dam that resulted in the flooding of Johnstown, Pennsylvania; and the 1988 PEPCON (Pacific Engineering Production Company of Nevada) jet fuel plant explosion.
