Titanic
- The sinking of the supposedly "unsinkable" ship on April 14, 1912, will forever remind us of our human hubris. A series of factors contributed to the ship's sinking that fateful night, including several design flaws.

Quebec bridge collapse, Canada
- This bridge collpased twice: first in 1907, and then again in 1916. This was due to preliminary calculations not being properly checked during the early planning stages. Essentially, the bridge was way over its carrying capacity, which led to the devastating disasters.

Historical engineering mistakes and their outcomes
The consequences were catastrophic and fatal
© Getty Images
Everyone makes mistakes, and engineers are no exception. The big problem is that some mistakes can have disastrous consequences, and many engineering mistakes, in fact, do.
We're all familiar with a number of disasters that were caused by major design faults. Many people have lost their lives because engineers wanted to take shortcuts, use cheaper materials, were negligent, and in many cases, just plain wrong at the design stage.
These errors occur across different areas of engineering, from civil to aerospace, among others. In this gallery, you'll find some of the biggest mistakes in the history of engineering, the majority of which had disastrous consequences.
Click through and get to know the biggest engineering mistakes of all time.
