Let me fabricate the quasibunk "the bridge collapsed *because* they cut the ribbon".
Come on boffins - debunk me!
why else would it collapse? someone below dislodging a support?Let me fabricate the quasibunk "the bridge collapsed *because* they cut the ribbon".

I'd handwave this away with vibratory mode not anticipated by the builders. triggered by the sharp impulse from releasing the tension on the handrails—sort of like the amateur version of the Tacoma Narrows bridge failure.
they're still perpendicular on the other side?However, nothing was keeping the rails perpendicular to the bridge's surface apart from the ribbon
Good spot. Maybe this was take two!
The ribbon is already broken before the cut/collapse, he is holding one end of it.
The loose end is being held up by the wind.
