Tacoma Narrows Bridge Collapse

Crash without test,
Fatality
1940 Tacoma Narrows Bridge: slender, elegant and graceful, the Tacoma Narrows Bridge stretched like a steel ribbon across Puget Sound in 1940. The third longest suspension span in the world opened on July 1st. Only four months later, the great span's short life ended in disaster. "Galloping Gertie," collapsed in a windstorm on November 7,1940. A dramatic tale of failure and success. The story of the failure of the 1940 Narrows Bridge and the success of the Current Narrows Bridge is a great American saga. When Galloping Gertie splashed into Puget Sound, it created ripple effects across the nation and around the world. The event changed forever how engineers design suspension bridges. Gertie's failure led to the safer suspension spans we use today.

We've seen a lot of neat stuff come from the Speed Cubing crowd. However, solving a Rubik's Cube while blindfolded is a new level of cool from a somewhat geeky hobby.
