News this week of the new Tacoma Narrows Bridge got us thinking about famous engineering screw-ups:
"The original Tacoma Narrows Bridge, dubbed Galloping Gertie, was the world's third-longest suspension bridge when it opened on July 1, 1940. It collapsed in a windstorm about four months later, becoming famous as "the most dramatic failure in bridge engineering history."
Most engineers are familar with this notorious bridge incident, having learned about it in a basic physics course. See some great video here.
Coming up with ten examples of engineering-gone-wrong was a challenge, as the culprit of so many calamities is not bad engineering (safety factors at work here), but rather a motley assortment of organizational incompetence, exaggerated marketing claims, and operator error and misuse.
Here are our picks, in no particular order:
1. Tacoma Narrows Bridge
2. Big Dig Tunnel (Boston, MA)
3. Ford Pinto
4. Bridgestone/Firestone Tires
5. Space Shuttle Challenger
6. London Millenium Footbridge
7. Aloha Airlines Flight 243
8. Hyatt Regency Walkway (Kansas City)
9.Maytag Front-Load Washing Machine
10.Denver Airport Baggage Handling System
And just for fun, here's a photo of the mold problem implicated in the Maytag recall, thanks to a frustrated former Maytag customer, Thomas F. McLoughlin (who as a VP of Engineering knows something about good product design!).

London Millenium Footbridge - a bit of a shame to see this on the list of 'biggest engineering mistakes'.
I remember the controversy well, but it is still a beautiful bridge!
IIRC it was followed by a similar issue with a stand at Liverpool's football ground. Newly opened, for a friendly game, the 'bouncing' Celtic fans caused serious structural concerns...

The exuberance of British football fans is well documented. I suppose that is now taken into account in calculating the dynamic load on the structure!

What no mention of the Tay Bridge Disaster?
Immortalised by William McGonagall
Beautiful Railway Bridge of the Silv'ry Tay!
Alas! I am very sorry to say
That ninety lives have been taken away
On the last Sabbath day of 1879,
Which will be remember'd for a very long time.
the official report of the time blamed design and poor materials. The remains of one set of the pillars have been left all the way along one side of the existing bridge as a permanent reminder for the future. Build Safe!

I'm not sure if the Challenger should really be put in this list (although I could agree with the Columbia) - the engineers knew that they were flying outside of specified parameters (it was too cold), told the manglement not to fly on that day but were overridden anyway.
