[W:57: 1585]Evidence that 9/11 was an inside job.

re: Evidence that 9/11 was an inside job.[W:57]

So our problem is the physics of skyscrapers. With 9/11 we are dealing with two skyscrapers having 110 levels above ground and six levels below ground. Doesn't that mean that every level must support the weight of all of the levels above it?
No. You can't use "level" as an all encompassing term without explaining that each "level" has different structural subsystems designed for different load bearing capacities as explained next. Only the columns at each level supported the weight above said level. The floor subsystem connecting to the columns was designed to support their own weight plus any live loads placed on them.
 
re: Evidence that 9/11 was an inside job.[W:57]

So our problem is the physics of skyscrapers.
No it's not "our" problem. It's YOUR problem. You don't understand how to apply physics to a structure.

Yeah, yeah, yeah.

Newton's 3rd Law of Motion went on vacation that day.

Newton's Third Law

If the top LEVEL of the stationary portion was crushed, then the bottom LEVEL of the falling portion had to be crushed. Those TWO LEVELS being crushed would require energy. The falling portion would have to lose kinetic energy. It would slow down. Then two more levels and two more levels. So the falling portion would run out of levels and energy first.

Below is a video that shows what you claim is impossible due to Newton's third law.

Explain how the smaller, upper section of the structure in the video destroyed the larger, lower section. According to your understanding of Newton's third law, this shouldn't happen.
 
re: Evidence that 9/11 was an inside job.[W:57]

I decided to start a thread to ask for evidence that 9/11 was an inside job. A little background on me, I used to believe 9/11 was an inside job. what convinced me was things like the buildings supposedly falling at free fall speeds, the flash just as the plane hit the towers, Building 7's collapse, etc. I believed because frankly I didn't challenged the evidence presented to me. it wasn't until I decided to challenge and try to debunk my beliefs that i realized how wrong i was. At least so I believe. I'm more than willing to return to believing that 9/11 was an inside job if presented with irrefutable evidence. I'll start off with the claim that the towers feel at free fall speeds. If you watch a video filming the event (I'll come back with an example later), the debris from the tower is actually falling faster than the tower itself. Thus supposedly disproving the free fall claim. Any counter to this?

I'm one of the nuts that finds neither side entirely convincing. The truthers are short on a body of facts that provide a complete, cohesive narrative. The gubment story supporters are stuck with excusing a number of improbable coincidences that amounted to a perfect storm.

I have decided that I'll probably never be entirely convinced one way or another. And I'm okay with that.
 
re: Evidence that 9/11 was an inside job.[W:57]

Another point you cannot prove. Certain facts suggest that American Airlines had cancelled its contract with Airfone months before September 2001.
Evidence?
ANY phone calls made from private cell phones, and there were several, were impossible. If you bother to read the transcripts of the conversations between Betty Ong and her dispatch, and if you know anything about how the airlines operate, you would understand the utterly theatric and unnatural qualities of the conversations.


So you're an air traffic controller or pilot? BTW, here's an article from a 9/11 truther debunking this conspiracy.

9-11 Review: ERROR: 'The Phone Calls were Fake'

Not so simple, eh?

Simple and honest would be your answering the question: How much knowledge or experience do YOU have with pre-2008 cell phones?

Honestly not much. But why would that matter? I can always post articles from people who do have vast knowledge on the subject.
I do not expect honest or simple answers from a person that still supports the official story almost 17 years after the events. From a person like that, I expect Cognitive Dissonance in full bloom. Thank you for delivering my expectations.

I guess you didn't read OP. I'm a former 9/11 truther. I used to believe 9/11 was an inside job not too long ago.
 
re: Evidence that 9/11 was an inside job.[W:57]

Three pages and no evidence that 9/11 was an inside job. There is a number of derail attempts. If someone can provide the links to evidence that it was an inside job, please do so.

These threads always take this course. Truthers do not have evidence of an inside job.

Here's the video I promised eariler along with a link to an article.

https://www.youtube.com/watch?v=nN3qUXJp7l0

Watch that video at 6:13.

We are supposed to believe that the columns broke in two places, above and below where the truss was attached, rather than the truss breaking loose from the spandrel.

Yeah right, create graphic videos to demonstrate the impossible. Look at the way those perimeter panels were made. THREE columns would have to break simultaneously, that is how many were connected to each spanderl panel. Since the columns were on the outside of the building they could dissipate heat to the air. Wouldn't the truss connections get a lot hotter? Wouldn't they weaken first?

How do you evaluate evidence when you can't use a little logic?

It is not about narrative. It is only about physics. No one can defy the Laws of Physics.

So why doesn't everyone want accurate data on the buildings?

We are supposed to believe that the columns broke in two places, above and below where the truss was attached, rather than the truss breaking loose from the spandrel.

Some of them did break away and I think you underestimate the strengh of the attachment points. Often times, the point of attachment is stronger than objects they want to attach.

THREE columns would have to break simultaneously, that is how many were connected to each spanderl panel. Since the columns were on the outside of the building they could dissipate heat to the air.

As I said, some of them did break away. And while I'm no engineer or expert on the subject, I wager the side of the columns closest to the fire got hot as well.

Logic is what caused me to realize that 9/11 wasn't an inside job.

Off topic. Do you have any evidence of an inside job? If not then please do not derail the thread.

Research the box columns yourself. They were 14 inches square and had to be strong enough to support weight further up the building which would include the outer halfs of all of the floors.. Each floor only had to support its own weight.

No, the idea that the floors broke the columns by sagging is nonsense.

Quit worrying about inside job and just analyze evidence, which means getting correct data about the building and the forces involved.

You think some stupid debunking video is going to explain the perimeter columns?

9-11 Research: The Perimeter Walls

There were 2600 panels on each building from the 9th floor to the top. An engineering magazine from 1970 said the heaviest was 22 tons. But we have not been supplied with data on how many different weights there were or the quantity of each. So where is any worthwhile evidence? But those trusses would have broken before the perimeter columns did from stress caused by the trusses.

zygy and mike are in my ignore list. Now I don't read posts without logging in. I had forgotten about them since last I was here.

That doesn't account for when presented with several hundred derees of heat for over two hours.

The link you provided have no data on how much pounds per square inch the columns can withstand, how much of that strength is weaken by the heat generated by the collision, and what is the breaking point of the columns when under those conditions.
 
re: Evidence that 9/11 was an inside job.[W:57]

Still no evidence / proof that 9/11 was an inside job. Wish posters would stay on topic.

Do you understand the difference between the temperature of a fire and the temperature of tons of steel that can conduct heat away from that fire? Two hours ain't squat.

How do you conclude the fire can heat 36 foot column sections on the outside of the building as well as trusses made of bent rods inside the building right above the fire? LOL

What do you know about the Cardington Tests in 1995?

Structural Fire Engineering: Database: Cardington Fire Test Data

Now this is really funny:

If you look in Wikipedia for jet fuel burning temperature you find:

Max adiabatic burn temperature 2,500 K (2,230 °C) (4,040 °F) open air burn temperature: 1,030 °C (1,890 °F)[9][10][11]

https://en.wikipedia.org/wiki/Jet_fuel

But if you go into the history for 2006 you find:

Open air burning temperatures: 260-315 °C

https://en.wikipedia.org/w/index.php?title=Jet_fuel&oldid=94143883

Adiabatc conditions gives a higher temperature. Is that what happens in a skyscraper fire? Why didn't that matter in 2006? It went adiabatic in 2014.

Ok, and how does any of this relates to what happened at the towers?

I certainly used to be a skeptic; still question the pentagon hit. But, for the most part, I'm good with what I hear happened: 19 hijackers smashed jet planes into buildings, two really big ones collapsed due to fire and structural damage.

I do appreciate that scintilla of honesty, that you've no experience with pre 2008 cell phones, and I copy your ignorant statement that it wouldn't matter. Ignorance on any given technical issue like physics is a common trait of the gullible and easily led.

There comes a point when someone just starts looking stupid.

Investigations by the Federal Emergency Management Agency and the National Institute of Standards and Technology (NIST) have concluded that the buildings collapsed as a result of the impacts of the planes and of the fires that resulted from them.[39][40] In 2005, a report from the National Institute of Standards and Technology concluded that the destruction of the World Trade Center towers was the result of progressive collapse initiated by the jet impacts and the resultant fires. A 2008 NIST report described a similar progressive collapse as the cause of the destruction of the third tallest building located at the World Trade Center site, the 7 WTC. Many mainstream scientists choose not to debate proponents of 9/11 conspiracy theories, saying they do not want to lend them unwarranted credibility.[41] The NIST explanation of collapse is universally accepted by the structural engineering, and structural mechanics research communities.

When it comes to Trutherism, that point has long since passed.
