America's Costliest Natural Disaster: Rust

Jonathan Waldman, author of "Rust: The Longest War," provides an illuminating look at the unsung heroes—engineers—who are working to keep our modern world from wasting away due to rust, which has been called "the great destroyer." Rust consumes cars, fells bridges, sinks ships, sparks house fires, and nearly brought down the Statue of Liberty. This program is a Trent R. Dames Lecture.
