Some connections broke as the bolts snapped, leaving many panels randomly scattered.[48] Significant parts of the naked cores (about 60 stories for the North Tower and 40 for the South Tower) remained standing for a few seconds before they also collapsed.[44]

And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

Mechanics of Twin Towers' collapse

The lower portions of both buildings' cores (60 stories of WTC 1 and 40 stories of WTC 2) remained standing for up to 25 seconds after the start of the initial collapse before they too collapsed.[44]
9/11 and the Science
of Controlled Demolitions

3WHAT ABOUT THE ALMOST FREE-FALL COLLAPSE OF THE TWIN TOWERS? The key is the “almost” modifier. If I told you I was making almost $100,000 and you found out I was making only $67,000, you’d say I was exaggerating. So stop exaggerating the collapse speed of the WTC Towers! The 80,000 tons of structural steel slowed down the collapses of the Twin Towers to about ⅔ (two-thirds) of free-fall.3 And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

True or False. For WTC 1 and WTC 2, after the complete collapse of their floor systems, there were still core columns standing?
I'm going with True

Um, just one? They should ALL be standing if only floors fell. .

Obviously, you can see what some of the posters are up to on 9/11 threads . ALWAYS denying and/or NEGLECTING most if not all evidences presented and yet their "evidence" is truth and yours is bs, or saying " well, prove it to me" when you already linked to... or " a blatant lie".
Some people have some growing up to do still... or have some other ideas... guess which one it is...
Makes me laugh when people fall for that kind of stuff.
Btw, I'm the type who would call a spade a spade...

Have you even examined any close up photos of the impact zones in the towers? The amount of damage was immense.
Also the towers structural integrity came from the exoskeleton and the inner core.
The building were not a solid mass and the connections are not made to withstand a kinetic downward load of such force and mass.
It really is that simple. The buildings were subjected to forces outside of their design specifications and to be honest it is quite a engineering feat that they stood standing for that long.

INQUEST INTO THE DEATH OF KATIE BENDER ON 13TH JULY 1997
EXECUTIVE SUMMARY
www.courts.act.gov.au...
The fragment travelled approximately 430 metres at subsonic speed and struck Katie Bender about 3.1 seconds after it was launched killing her instantly. The fragment broke into a shape that could be expected when an explosive charge is placed against steel backing plates and columns in the fashion used by the explosive subcontractor, Mr. Rod McCracken of Controlled Blasting Services. The impact velocity, calculated by Dr.. A. Krstic of the Defence Science and Technology Organisation, Department of Defence, Salisbury, South Australia was 128 – 130 metres per second. The associated kinetic energy was 8.172 kilojoules.

It's just impossible for it not to be a controlled demolition. How does a plane fire weaken the crucial points for the buildings to fall. There were survivors at point of plane impact. There's no way it would cause a buildings crucial structural points to weaken. Also, if one plane got lucky to weaken the crucial points on the building, it would be nearly impossible for the second plane to do so.
Why does a fire so high up cause the entire building to collapse? I mean maybe a partial collapse, but the whole thing? No way, just not possible.
How the hell did those arabs find the twin towers? Doesn't seem likely they just looked out the plane window. It's really hard to pilot a jet liner like that.
Basically, there were TOO MANY PERFECT EVENTS:
1 - the muslims just happened to be expert pilots, better than real pilots (even real pilots would have a hard time pulling this off -- let alone twice -- yet two inexperienced muslims did so within minutes of each other)
2 - muslims in both planes found the twin towers from cockpit view (kinda hard to find landmarks like that up from the sky and having narrow view from cockpit)
3 - muslims managed to expertly crash both planes into the twin towers (it's a really chaotic ride down, you would really have to understand how a plane descends, to perfectly nail this ... twice [it would be a miracle if one muslim pilot pulled it off, but two muslim pilots within minutes of each other? ... not possible])
4 - BOTH the twin towers magically fell in perfect downfall when no fire ever brought a building like that down, but this happened TWICE in one day. It would make sense if one tower partially fell over to the side, but BOTH fell down in perfect freefall. WTF?
5 - tower 7 magically fell in perfect demolition ... why the hell did it fall? It was nowhere near tower 1 or tower 2
