The NOVA simulation shows the central core untouched like a central spindle on a record player. The core ..... 47 massive columns, 52 inches by 22 inches at their base - fabricated in lengths of up to 5 inch thick steel, on the lower floors they had solid steel slabs running through their centres ..... were considered by the architects and engineers who built the towers to be virtually indestructible in normal circumstances.
The Nova clip shows trusses, completely independent of the reinforced concrete floors and all the interlaced cross beams and steel floor panels. The BBC clip takes 12 seconds. It shows a computer simulation of beams slowly dropping directly onto a beam below. The simulation leaves the main core structure undamaged in the background of their representation. NOVA also leave out the external steel columns that carried over 25% of the weight. On the day, in 12 seconds, the bulk of both 110 floor towers had turned to shattered rubble and dust.

NIST: “NIST’s findings do not support the “pancake theory” of collapse, which is premised on a progressive failure of the floor systems in the WTC towers… Thus, the floors did not fail progressively to cause a pancaking phenomenon”.3
Agreed: the “pancake theory of collapse” is incorrect and should be rejected. This theory of collapse was proposed by the earlier FEMA report and promoted in the documentary “Why the Towers Fell” produced by NOVA.7 The “pancake theory of collapse” is strongly promoted in a Popular Mechanics article along with a number of other discredited ideas.8, 9 We, on the other hand, agree with NIST that the “pancake theory” is not scientifically tenable and ought to be set aside in serious discussions regarding the destruction of the WTC Towers and WTC 7.
