[00:00:00]November 7th, 1940.

[00:00:01]>> [music] >> Puget Sound, Washington.

[00:00:04]The third longest suspension bridge in the world, the Tacoma Narrows, >> [music] >> is a slender, elegant ribbon of steel.

[00:00:12]But since it's opening, [music] the locals have called it Galloping Gertie.

[00:00:17]In even a slight breeze, the road deck undulates and bounces, [music] a phenomenon the engineers dismiss as harmless.

[00:00:25]>> [music] >> On this morning, the wind hits 42 mph.

[00:00:29]Gertie doesn't just bounce, >> [music] >> she begins to twist. The flat plate girders act like sails, catching the wind and forcing the bridge [music] into a violent torsional vibration.

[00:00:41]The 2,800-ft span begins to warp 45° from the horizontal, the steel cables groaning and snapping under the impossible torque.

[00:00:52]A single car is abandoned on the center span.

[00:00:55]>> [music] >> For hours, the concrete deck behaves like a liquid, twisting and rippling until the steel supports reach their breaking point.

[00:01:04]At 11:00 a.m., the main [music] span shatters.

[00:01:08]Thousands of tons of concrete and steel plummet [music] into the churning waters of the sound below.

[00:01:13]The bridge that danced until it died.
