9/11 North Tower WTC 1 Demolition 20 Blocks North With Standing Core Spire

NIST WNBC Dub10 Clips 49-54. How can a single column of steel be standing vertically 60 floors up in a collapse scenario? The floors above would have crushed it. How is the core spire piece still straight? Everything around it was blasted to dust and the demolished building above did not provide enough downward force to crush it. There would not be another answer since the building fell in on itself. The lower building was not damaged by fire but also blasted to dust with little resistance. ~10 seconds/110 floors = ~11 feet of downward travel every 1/10 second = ~1 foot every 1/100 second through 100 stories of over-engineered steel and concrete structures. A lead ball dropped from the roof would take 9.2 seconds. All that steel and concrete provided .8 second resistance? That is 8/1000 second resistance for 100 individual floors. Collapsed? Impossible in that time frame. In order for the building to fall that fast every connection and every piece of support steel would have to be removed instantly and allowed to fall like a rock or blasted and sucked into a vaccum created from explosions underneath.
