You keep putting the cart before the horse and forgetting it can't go anywhere on its own. Of course, I have seen you try to get around that by insisting a 207 foot square 73 million lb. 12 story section of building just shifts sideways somehow so that the columns miss each other. In reality once loosened the upper 12 story section would fall in place as there is no lateral load to shift it.
The asymmetrical nature of the destruction led to asymmetrical support of the upper floors and this induced rotation when the capacity of the columns dropped below the imposed loads which caused a rotation... and this was all it took for the remaining connected column ends to rotate and break free. Same think happened in 2WTC, but the mechanical damage was ever more off center and the rotation greater. The columns ends where the connections were had no lateral restraint and were simply more like alignment splices at 4' above the floor line were the bracing and lateral restraint was.
Your understanding of how the damage at the core manifest is incorrect... but it enables you to construct your irrational belief that explosives or placed devices account for the rotation or the lateral movement. And just how would they have accomplished that?
