There are so many good videos of the Tacoma Narrows disaster that it was hard to choose. There must have been more than one person filming it, as you can see it from so many different angles. This one is called a newsreel, but seems too long for that. Still, it wins points for the histrionic narration ("There it goes!") and the music, which seems to have been lifted from a bad Western.
It's fascinating when a human project fails this dramatically! Poor Tubby.
