Bandaged ice that stampedes inexpensively through
The exterior corner connections were severed once things were moving to help continue propagation by removing orthogonal support of the perimeter walls and decreasing their resistance to the point where they could not sustain a static load.
In your fantasy world, how long after the beginning of the collapse were the corner connections severed, and more importantly, why bother? Although you'd rather die than admit it, I know you don't subscribe to the David Chandler school of outright progressive collapse denial, so you understand that the perimeter alone couldn't arrest collapse once the core was gone; why do you imagine the conspirators chose to advertise their duplicity in the most public way possible by blowing up the most visible part of the structure when it didn't even need to be done?
