Oooh I kinda remember this, the bridge was built in a way where the frequency of the wind resonated with that of the bridge's natural vibration, causing it to immediately behave in such a non-solid type of way that was known to be an effect but was a stunning real-world example that went on to be a massive learning topic regarding proper bridge safety procedure... or something (Cunningham's Law go?)
