LAB1-086 · Galloping Gertie — Go and look
Newsreel footage of the Tacoma Narrows Bridge's catastrophic failure on November 7, 1940, shot by Barney Elliott and Loren Corey. Silent, black-and-white, 4 minutes. The only complete visual record of a major structure's collapse, and the primary source around which engineering explanations have shifted three times in eight decades.
