Tacoma Narrows Bridge collapse November 7, 1940

Many introductory physics classes show this classic bridge collapse, due to a bridge that was built to be too flexible and which collapsed in high and gusty winds after oscillating wildly back and forth in the Tacoma Narrows in Washington State.  You can read about the event and the science behind it at Wikipedia here or watch an old-time video of it at https://www.youtube.com/watch?v=nFzu6CNtqec and https://www.youtube.com/watch?v=lXyG68_caV4.
