Collapse of the twin towers in 2001. An engineering perspective

[marks]

There is no way those buildings could free fall.

Bolts on the levels below were not effected by heat and would not all shear so easily. If all the bolts on the levels below were shearing there should have at least been resistance and considerable deceleration. But we didn't see that. We saw gravitational acceleration. No resistance at all.

It wasn't just bolts that sheared, it was whole colums. Columns should be buckling and that should be causing a massive deceleration.

Keeping in mind the concrete/steel core of both buildings as well.

Before 9/11, I didn't know what demolition squibs were. I didn't understand why I saw symetrically places puffs of smoke every 3rd floor or so, blowing out as the top of the building dropped.

Much love!

The biggest objection I have with this is the logistical complexities that would be involved in such an operation. The preparation alone would be extensive. You would need dozens, if not hundreds, of workers setting up equipment, laying cables, and removing or modifying structural elements for possibly months ahead of time. There would be equipment lying around, noises, and people going in and out of restricted areas of the building. How would anyone possibly not notice that was going on? Then how would you guarantee that those involved never talked about it? Those are obstacles that are too big for me to accept.

That's a fair enough point. They would of needed special access to plant all those charges. Not an impossible task but. A company could of been hired for maintenance job on the buildings when really they were planting charges.

But our assessment is just from an engineering standpoint. It's impossible for those buildings to free fall like that.
Logistics and motives is something that I'm not too sure about and can be discussed also.

Motive is something I always struggled with. At first we thought the terrorists must of planted the charges. Then people started saying it was the government that did it. But what would be the motive. People would say so they had an excuse to go to war. But I don't think America would need to do such a terrible and drastic thing go to war. So if it wasn't the terrorists then the motive still baffles me.

One thing I'm confident about is that they lied about planes causing the collapse of the twin towers and building 7. Why. I don't know
