you are right that in classic CD, most of the dust comes from the free falling concrete. But there are two important points: you actually need demolition charges to enable the free fall. And when you see a free fall, the gravity doesn't crush almost anything on the way down, but only on the ground level. Just like WTC7 - gravity did most of the work there too, and debris was all in 60 feet radius.
Another side of the coin is that in WTC1 for example we see the thick dust cloud during the falling period:
So no kinetic energy has been transformed to destruction of steel structure or floors, nothing visible is crushing anything, and yet we already have the dust could, which in the Fort Worth case required all the potential energy of the demolished building. So in Texas you say that you need all the energy for this dust cloud, and in NYC you can do it without anything hitting the ground?
anyways thanks for your comments, bed time.
This is why you fail.
You see a single dust cloud eruption when in this photo there are at least eleven. Each caused by the crushing you say you cannot see. Each fountain of dust is caused concrete floor segments slamming into the floor below it. It is not a uniform collapse.
You keep asking for your four points to be answered, yet it's right there in this picture. In those fountains of dust are some of the body parts of the remaining people trapped in the top floors. The pattern of body parts follows the fallout from the dust could at it's ground terminant.
One final thing to ponder, many of those dots on your map are from on person.
