The book examines how engineering failures happen—not just because of design errors, but due to a complex mix of human, social, economic, and cultural factors. He reviews famous disasters—from bridge collapses and oil spills to structural collapses—and shows how failing to anticipate failure, or admitting risk, often worsens outcomes. Ultimately, the book argues that understanding and owning up to failure is essential: failures teach lessons that lead to safer, more thoughtful design.
