World Trade Center 7 Explosion and Controlled Collaspe Caught on Tape.

a reply to: Informer1958

Fact is all those buildings are not at ground zero.

The blast wave effect on the steel structures is the same as conventional explosives at closer range. That is why the bomb used in the 1993 bomb attack on WTC 1 failed to dislodge its steel columns.

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

Actually, that is what structural and civil engineers and firefighters have concluded.

It was, the pancake answer was to fool the masses, it did not happen.....

Actually, anyone with even a fundamental understanding of basic physics and reality knows that this is exactly what happened.

You only have to look at this photo of a portion of the central core that is still left standing in the absence of its attached floors. Structural and civil engineers and even firefighters, have confirmed that the floors pancaked.

Which is why structural and civil engineers, demolition experts, firefighters, and investigators concluded that the floors of the WTC Towers pancaked.

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.

Correct, far to many drink the kool aid....

Well, after 14 years, the pancake conclusion still stands.

Only in your mind, After years of studying NIST has debunked the pancake theory - bravo.

Not even in the official story...

NIST’s findings do not support the “pancake theory” of collapse

That won't fly, simply because structural and civil engineers, firefighters and demolition experts have concluded that the buildings suffered from a pancake collapse. It's history already.

You push the OS and now you disagree with the OS ? NIST realized the pancake story would not stand up so they changed there story and now you say you know more than them, ROFLMAO......

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

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.

What do structural engineers think are the reasons behind collapse of the World Trade Center Twin Towers?

First and foremost, an overwhelming majority of structural engineers agree that the tragedies of September 11 were the result of a terrorist attack that caused catastrophic damage to WTC 1 and 2. The following is a succinct version of the accepted explanation:

The impact of the airliners and the initial explosion caused localized damage and collapse of the steel structure over multiple floors. The initial impact significantly reduced the capacity of the structure to withstand any additional damage. Ensuing fires caused by the ignition of jet fuel and surrounding office contents burned long enough (about an hour) to weaken the load carrying capacity of the remaining steel frames.

The columns were supporting floors above (12 floors in the case of WTC1 - which my rough estimate puts at about 48 Million pounds of weight). Contrary to myth, steel members subjected to fire do not have to approach a melting point to lose their design capacity.

When considering that the remaining steel framing was already being forced to carry loads above design capacity (on account of members damaged during impact), it is reasonable to assume that induced thermal stresses lead to their failure. Upon failure, the previously estimated 48 million pound load accelerated downward, resulting in progressive collapse of the structure.

Upon collapse of WTC 1 and 2, the corresponding debris field resulted in further damage, fires, and in some cases collapse of surrounding structures.

Post all you want, NIST is the authority on 911 and they say no pancake and I agree with that...

Yep. The intellectual equivalent of plugging your ears. It's just that simple.

I agree with structural experts, civil engineers, firefighters, and demolition experts supporting the pancake collapse. In fact, some firefighters have stated for the record that they heard the floors pancaking and I have posted their statements as well.

No that was those pesky man hole covers they heard.. lol really man it's Ok to be wrong........

All the credible experts including firefighters agree the WTC were destroyed by demolition.

The fact is anyone watching all the videos from the News media on the morning of 911 can clearly see that.

Another fact is, there are some people who do not want you to see that, they want your eyes to lie to you.

Fact is the WTC had to be torn down according to the EPA reports stating that the WTC were build with a lot of Asbestos.

Fact is the Port Authority was ordered by the EPA to do an asbestos removal program floor by floor.

Fact is Port Authority complained it would cost millions to scaffold the entire WTC for abatement removal of the asbestos.

Fact is 1998 & 1999 the Port Authority submitted demolitions plans to all three WTC to the City Council of NYC.

Fact is City Council voted no to the demolition of the WTC stating is was far to dangerous.

Fact is there was a plan hatched for 911 to happened and it is assumed Port Authority was contacted by the real criminals that they wanted to use the WTC as part of their plans for a SHOCK and AH.

Port Authority went along with their plans because they were finally going to get rid of their Asbestos WTC at no cost to them.

Fact is the Bush Administration did not want any investigation into 911, because they were to busy covering up their complicity of pulling of the greatest False Flag operation in US history.

The crooks in Washington wanted a war and the American people would not support a war. However the crooks in Washington hatched an evil plan to fool Americans that terrorists living in caves in a third world country jumped in some airplanes and brought down all the WTC.

The mainstream propaganda prostitutes Press where eager to help and participate in the greatest False Flag event contrived and carried out on American soil

911 was a Master Piece for the propaganda media, it was their show. Interesting, within the hour of the attacks the media already had their boogeyman, ( Bin Laden ) every television show had their own experts, retired Generals and such doing talking points to sway the shocked American people that a CIA operative Bin Laden committed 911 using 19 hijackers and the hole world fell for their propaganda, and the American people wanted revenge.

The Bush Administration finely got the support of the American people to go to war. After 14 years and the cost from the American tax payers, billions of dollars were wasted and we are still at war, while the crooks in Washington are raking in all the profits.

This still doesn't address the point I made regarding the steel core columns. Yes, SOME were standing close to the ground level. But what about the VAST MAJORITY of the structure?

Pardon my estimate, but from the photos we see somewhere around 10% of the core columns intact. The rest of which couldn't have severed or destroyed from a jet fuel based pancake collapse. It's a physical impossibility.

It's your choice to take the words of civil engineers, etc. But they are people. People's words can be bought. Scientific facts are absolute and don't conveniently change to fit an agenda.

Furthermore, if outsiders' expertise is of utmost value to you, then why not take the actual architect of the towers' statement?

When he said in plain English that the towers were built with the capability to take impacts from multiple commercial airliners

It was all there at ground zero.

Which debunks the claim that demo explosives were placed and detonated at the base of the WTC buildings.

The rest of which couldn't have severed or destroyed from a jet fuel based pancake collapse. It's a physical impossibility.

Actually, it was expected. Once the top floors pancaked unto the lower floors, there was nothing to stop the collapse.

Which they did, but the designers did not take into an account the fact that the steel structures were exposed to the direct effects of uncontrolled fires. At such temperatures, steel under structural loads will fail.
