Modern Marvels: Episode 50
Tóm tắt
What happens when the calculations of builders and engineers prove wrong and their constructs come tumbling down? In this episode, we examine the 1987 failure of the Schoharie Creek Bridge in New York; the partial destruction by a runaway freighter of the Riverwalk Marketplace in New Orleans in 1996; the roof collapse of the Rosemont Horizon Arena in Illinois in 1979; the deadliest grain-dust explosion on record in Westwego, Louisiana, when a grain elevator exploded in 1977; and the crash of the British R101 airship in the 1920s.

Cutting, digging, picking, stripping, shaking, and raking–whatever the crop, there's a custom machine to harvest it. It all began with handpicking and today it's often one man and one machine harvesting hundreds of acres in a single day. The farmer may even get a little help from satellites. Far above the earth, high-resolution photography is giving the grower more opportunities to cut costs and maximize the harvest. From the debut of the sickle in ancient Egypt to McCormick's famous Reaper to the field of ergonomics that assists human harvesters, we'll dig into the past and future of the harvest.

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.

One of the youngest and smallest nations, Israel has produced some of the world’s fiercest weapons. In 1952, shortly after its War of Independence, Israel unleashed the Uzi…a submachine gun that set the standard for nearly 50 years. Between 1950 and 1980, Israel fought three wars, and superior weapons became a matter of survival. We examine the Negev Machine Gun and the Galil Assault Rifle, designed to survive the rigors of desert warfare, and the Tavor 21, a lightweight 21st-century assault rifle.

A look at the technology that changed the serious game of Search and Rescue forever. At the mouth of Oregon’s Columbia River, we visit the Coast Guard’s Motor Lifeboat School, the training ground for High Surf Rescue. Then, we trace the evolution of life-saving technology at sea, and learn why the EPIRP (Emergency Position Indication Radio Beacon) is the pleasure boater’s greatest friend. And we take a look at how the U.S. Navy deals with accidents classified as “Man Overboard” in the 21st century.
