If this has been posted before I apologize. There is a small part where they clai m that the core it still intact, initially, then it falls. What
you you all think of this? I personally dont think that this much of the core would be remaining then just disappear. They also try to debunk the
freefall speed. i just want thoughts.

If the cores had still been intact before, during and after the collapse, people could have seen 1300'+ feet of core still standing in the air. Each
core support was one continuous unit from lowest sub-level to the top.

"The core of each tower was a rectangular area 87 by 135 feet (27 by 41 m), and contained 47 steel columns running from the bedrock to the top of the
tower.[48]"
In order for the buildings to fall the way they did, at the speed they did, all significant resistance has to be symmetrically cut at the center.
Otherwise, cut any other way, the buildings fall in the direction of the unevenly cut supports and can topple. Free fall is falling with the least
air and material resistance.
Taking Rosie's example, if a ball was dropped from the top of a twin tower, it has only air resistance and swiftly hits the ground in less than 10
seconds. If there are something, such as hortizontal cantilevers protruding from the side of the building, and the ball hits those along the way, it
has material resistance and takes much longer to reach the ground.
It takes minutes when there is support resistance on every floor, and the time depends on how many floors are going to fall toward the ground. The
floors would have peeled from the center core surrounding the core supports. Leaving the core supports intact and still standing and very little if
any compromise to the other three walls.
When support is resisting the force of mass and weight, kaboom.....kaboom.....kaboom etc will be heard and each floor dropping will be easily seen.
That is because it takes time for the upper section dropping to break through the supports on the lower sections, regardless of mass and weight. Mass
and weight amount can cut down the time it takes to break down the support resistance, depending on the amount of the upper mass and weight.
There would have been no mammoth clouds of concrete dust debris, because there would not have been enough force to pulverize the concrete floors or
any other concrete in the twin towers. Resistance always slows momentum, particularly vertical support resistance, regardless of weight and mass.
Free fall allows weight and mass to gain the most momentum and gravitational velocity force pull, without any significant resistance to encumber the
fall.
To fall symmetrically, the building supports had to be cut symmetrically at the center.
