Ships, bridges, and tall buildings are marvels of engineering. They are designed to be strong and safe. But even state-of-the-art designs don't always hold up in the real world. Learn about the biggest engineering goofs throughout history--from bridges that collapsed to ships that sank. Discover how engineering mistakes have also led to improvements, such as stricter building regulations and the use of sturdier materials.
