"Armies are trained to break step when crossing bridges; if they all marched in time, and their pace happened to match a resonant frequency of the bridge, there would be a serious danger of collapse."

Never realized this was possible. Cool site, Thanks BrainCase

I saw a show on the History Channel (or maybe it was Discovery or something like that) where they said that the longstanding theory that "the Tacoma Narrows Bridge was ripped apart by a complicated resonance effect" had been disproven. I don't know if that's true or not, but it brings into question just how much possibility there really is that a marching army would cause a collapse.
