The collapse of the bridge was recorded on movie by Barney Elliott. He was the owner of a local camera store. The movie shows Leonard Coatsworth leaving the bridge after exiting his car. In 1998, "The Tacoma Narrows Bridge Collapse" was chosen for preservation in the United States National movie Registry by the Library of Congress. It was chosen because it was culturally, historically, or aesthetically important. This footage is still shown to engineering, architecture, and physics students as an example of what can go wrong. Elliot's movies of the construction and collapse of the bridge were shot on 16 mm Kodachrome movie. Most copies are in black and white. This is because newsreels of the day copied the movie onto 35 mm black-and-white stock.
