Modern Marvels - Season 10 Episode 86 Engineering Disasters 5

Examines some of the most notorious engineering failures of recent years and asks what went wrong and what we learned from them. We take viewers to the southern coast of Louisiana, where a misplaced oil rig caused an entire lake to be sucked into an underground salt mine; review the 1972 Buffalo Creek dam disaster; revisit the Exxon Valdez oil spill; see how radio and TV antenna towers collapse with alarming regularity; and look at the collision of two California icons–freeways and earthquakes!
