How did the first bridge collapse at the Tacoma Narrows?

The simple answer to the collapse of "Galloping Gertie" across the Tacoma Narrows is that wind initiated some motion in the bridge, and this combined with the natural mode of vibration of the bridge. This resulted in the bridge going into harmonic motion, or oscillation, and the movement increased to the point of destruction. The "fancy" term is aeroelastic fluttering.
The "pet name" for the bridge was Galloping Gertie, and it earned the nickname from the motion drivers sensed as they crossed over the bridge in a wind. The bridge only lasted a few months before it failed. A link can be found below. And video footage is available on YouTube if you've never seen it. A link can be found to that, too. It's spectacular in an engineering sense.
