Modern Marvels: Engineering disasters can result in personal tragedy, national humiliation, and economic ruin. But buried within their wreckage lie lessons that point the way to a safer future. The fire at the Las Vegas MGM Grand Hotel, the collapse of Seattle's Lacey V. Murrow Floating Bridge, the car that spurred creation of the National Highway Transportation Safety Administration, and the flaw that grounded the first commercial jet are among the engineering disasters that led to improvements in design and safety.
