Actually not. Check it out.

Context is your friend, not.
"Vanished" as in "lost evidence", thanks for not minding to click that damnd link at all.

At least you memorized our discussion regarding vanishing cores.

The OS side has already proved how the buildings came down.
The world has produced thousands of new engineers since 911.
You don't hear them complaining about the science.
Only a handful of web warriors with no degree go on about it.

The OS??

I am using logic, not mainstream media propaganda garbage to get to the truth of this matter.

Perhaps you believe in the OS and that's ok with me, however I don't. If It walks like a duck...

I suppose you believe thousands of tons of steel, being blasted upward and outward from the WTC is a normal free fall to a natural collapse?

a reply to: PublicOpinion

It's all there that the sound they heard were floors collapsing upon one another. We can also go here.

Civil & Structural Engineers on WTC Collapse

The heat from an ordinary office fire would suffice to soften and weaken the unprotected steel. Evaluation of the effects of the fire on the core column structure, with the insulation removed by the impact, showed that collapse would follow whatever the number of columns cut at the time of the impact."


Why the World Trade Center Buildings Collapsed: A Fire Chief ’s Assessment

The jet collapsed the ceilings and scraped most of the spray-on fire retarding asbestos from the steel trusses. The steel truss floor supports probably started to fail quickly from the flames and the center steel supporting columns severed by plane parts heated by the flames began to buckle, sag, warp and fail. Then the top part of the tower crashed down on the lower portion of the structure.

This pancake collapse triggered the entire cascading collapse of the 110-story structure.

There was no WTC steel that was blasted anywhere by explosives.

Scientist were able to prove using science that the floors did not pancake that was disinformation put out by propaganda media years ago and has now been debunked by very credible science.

If the floors just pancaked like you say, then why did thousands of tons of steel exploded outward and upward over 600 feet in mid air in all the videos that the hole world watched on 911?

What I see here is, there are some people who want our eyes to lie to us.

It is no secret that the floors pancaked, which firefighters have stated they heard.

The very videos you continue to post on all these threads depict what scientist have proved. Look at your own videos, the steel is not just falling down.

The fact is It is being BLASTED upward and outwards anyone can see that. We are not all blind. Some of us can see and don't let our eyes lie to us.

Yes and many of firefighters heard explosions, and some firefighters were in some of the explosions, however today No firefighter supports the pancake conspiracy theories.

a reply to: Informer1958

Those squibs are not evidence of explosives. That is compressed air and nothing to do with explosives. Check it out.

Photo 3: Squibs from Explosiveless Demoltion

However, I might add that your video debunks the claim that the WTC building collapsed at free fall speed, which is evident by the fact that debris in the video is outpacing the collapse of the WTC building.

David Chandler's video has been debunked.

As noted, they have stated that the explosions they heard were pancaking floors, exploding gas lines, and things that had nothing to do with explosives.

Did I say squibs? No I did not.

Watch your very own video, look at the photo of this video. It clearly shows the thousands of tons of steel being blasted upward and outward, look past the smoke on the right of your own video, you can clearly see thousands of tons of steel being blasted straight out.

The steel is not falling straight down is it? It is being blasted outward, straight up and outward.

a reply to: Informer1958

Those panels you see in the video are the light-weight exterior aluminum panels of the WTC Tower. Check it out.

Aluminum and the World Trade Center Disaster

Aluminum was present in two significant forms at the World Trade Center on 9-11:

(i) By far the largest source of aluminum at the WTC was the exterior cladding on WTC 1 & 2. In quantitative terms it may be estimated that 2,000,000 kg of anodized 0.09 aluminum sheet was used, in the form of 43,600 panels, to
cover the faÄade of each Twin Tower.

(i) The other major source of aluminum at the WTC was the aluminum alloy airframes of the Boeing 767 aircraft that crashed into the Twin Towers on the morning of 9-11. It may be estimated that, on impact, these aircraft weighed
about 124,000 kg including fuel; of this weight, 46,000 kg comprised the fuselage and 21,000 kg made up the mass of the wings – all of which were fabricated from aluminum alloys. Modern airframes are invariably constructed from series 2000 aluminum alloys. Alloy 2024 is a typical example containing 93 % Al, 4.5 % Cu, 1.5 % Mg, and 0.5 % each of Mn and Fe.

These metallic additions to aluminum lower the melting point of the alloy from a value of 660 C, for pure aluminum, to about 548  C for alloy 2024. This relatively low temperature indicates that the fires within the Twin Towers were quite capable of melting at least some of the Boeing 767 aluminum airframe structures remaining in the WTC before its collapse.

That is proven fallacy.

Someones "opinions" are not facts.


Furthermore everyone knows 911 Myths is a very biased debunking website that only supports the OS and nothing else.

How about presenting us some credible sources?

Funny thing is there was no aluminum panels found sticking inside other buildings, ONLY steel beam where found blasted into other buildings, there are plenty of photos all over the internet that depict this.

a reply to: Informer1958

Well, I can personally state that the WTC Towers were covered by aluminum panels because I have visited the buildings on multiple occasions.

There were aluminum panels lying everywhere at ground zero.

Well I can personally state that I worked in the WTC back in the 1980's and yes there was aluminum panels lying at ground zero, however there was no aluminum panels stuck inside of other buildings hundreds of feet away, ONLY steel, a few thousand tons of steel.

So if the WTC just pancake, please explain how did thousands of tons of steel landed in other building hundreds of feet away?

You have seen the many photos that depict this haven't you?

Which was the result of collisions during the collapse, not from explosives.

Once again, that was the result of collisions, which was demonstrated by a pencil striking a chair, not from explosives. Photos of bombed buildings have depicted steel frames of those buildings still standing despite the explosions.

This video demonstrates what I mean when I say that blast waves from bombs simply flow around a steel structure if not firmly attached. You will notice the steel structures in the following video withstood the blast effects of a nuclear detonation that demolished the wood frame buildings. Notice that the nuclear blast failed to throw the steel structures anywhere.

Once again I see no sources for this video?

Furthermore what your video is demonstrating is SHOCK WAVES not explosions. Nice try.

a reply to: Informer1958

It is an official government video.

a reply to: skyeagle409

It is an official government video.

Perhaps it is, however a source would be nice.

The video does not show any building just blowing up, what you are witness is the (Shock waves) after the bomb detonated.

Fact is all those buildings are not at ground zero.

If they were they would have all been vaporized.

Are we actually discussing "the pancake theory"? I thought that nonsense was dismissed a long time ago.

Sounds simple, because it is: If the floors detached from the trusses and caused a pancake type of collapse, WHAT WOULD BE LEFT STANDING?

Ohhhh right, the massive arrangement of core steel columns. I'm sorry but anyone who still entertains this theory is really drinking the kool-aid.
