lol.... At what point at all does it look “controlled”?
Controlled Demolitions don’t usually have a banana peel effect. Controlled Demolitions usually look exactly that, controlled.... none of which these did.

The design was a "tube in a tube" construction where the steel reinforced, cast concrete interior tube, was surrounded with a structural steel framework configured as another tube with the load bearing capacity bias towards the perimeter wall with the core acting to reduce deformation of the steel structure maximizing its load bearing capacity. All steel structures with the proportions of the WTC towers have inherent problems with flex and torsion. Distribution of gravity loads was; perimeter walls 50%, interior core columns 30% core 20%.
