A certain professor Z. Bazant of Northwestern University, Evanston, IL, has written many peer reviewed, scientific papers about this and he says that the average density of the total volume of the intact buildings, tops C and bottoms A, incl. everything was 0.25. It means that the weight of one cubic meter of the building was 250 kilograms. To be compared with one cubic meter of water that weighs 1000 kilograms.
You can conclude that the buildings were quite light as they contained mostly air.
Same professor, a stupid terrorist in my eyes that US Dept of War should imprison at Guantanamo at once, suggests that the average density of the rubble B of the buildings after 'collapses', when top C compress bottom A and itself C into rubble B, is 1! One.
It means that a 410 meters tall square (the footprint is square) building compresses into a 102.5 meters tall square rubble pile (with same foot print) when 'collapsing' (crush down + crush up) as follows according Bazant:
that then becomes a pyramid of rubble B - same density - with bigger bottom foot print and less height.
The US Journal of Engineering Mechanics, JEM, has published a scientific analysis by me - http://heiwaco.tripod.com/blgb.htm - of this strange phenomenom!
In response to your post.
I noticed a link that you included. Which led me to Richard Gage videos.
He still believes the (thermite) theory demolition, and pulverisation top down theory> Am i incorrect
with this thinking?

Now let me stop you at once: do not even try to promote that theory. We cannot have this discussion over and over again. Wood, whose head must be made of the same material,
