RARE 911 WTC VIDEO - Multiple Explosions Heard Before and During Collapse.

I admit I have not read every post in this thread so if I missed this, I apologize.

Buildings are full of various systems. Most large buildings have utility corridors and wet walls. Any pressurized system like a water system is susceptible to heat. Water, due to its fluid nature, can only be pumped so far above its current elevation. After that it must be held in a vessel from which it can pumped another distance above its current elevation, and so on. Each of these vessels and systems is under pressure and are chambered to prevent backflow. With a fire raging in the building, any one of these closed systems could explode due to the excess pressure resulting from elevated temperature and the weakened mechanical properties of the materials of construction due to the elevated temperatures. Water flashing to steam has an expansion ratio of approximately 300:1. That makes for one big noise and a lot of pressure when it happens. Water in a contained vessel can be heated beyond the point where it would normally turn to steam but remains liquid due to the pressure in the system. When the system ruptures, the heated water flashes quickly to steam with an explosion of concussive force. A chain of closed systems could be responsible for some of the internal explosions. The only water system that would have been flowing and incapable of reaching an explosive internal pressure would be the fire suppression system. The rest could have contributed greatly to the internal damage of the structure at various levels throughout the building. It is also worth mentioning that these types of systems are rarely air free. There is almost always air trapped in the system with the water. The water does not compress, but the air does. The rapid expansion of pressurized air would only add to the concussive force of the rapidly expanding steam flash. It all adds up to one big boom after another, provided of course that the systems in question were still sealed and segmented. I am sure this is one aspect of the failure that was examined but I have not heard specifically about that aspect as a contributing mode of failure. I am very good friends with a highly recommended forensic engineer. I will get his opinion on this subject and relay what I hear from him when I next speak to him.

In addition, not many people are aware that molten aluminum coming into contact with water will generate explosions, and there was lots of water within the WTC Towers along with molten aluminum from the burning airframes of the 9/11 aircraft and other aluminum contents from within those buildings and the aluminum panels on the facade of those buildings. Molten aluminum coming into contact with water has been known for its explosive potential.

Federal agency says molten aluminum hitting water apparent cause of Missouri plant explosion

MARSTON, Mo. – A federal agency says molten aluminum hitting water is the apparent cause of explosions that injured more than 30 employees at a southeast Missouri aluminum plant.

The U.S. Department of Labor's Occupational Safety and Health Administration says it's investigating two explosions that occurred Tuesday at the Noranda Aluminum plant in New Madrid County, about 170 miles south of St. Louis.

OSHA says the preliminary cause of the explosions appears to be the result of molten aluminum contacting water. The agency says it also investigated the facility in June after a worker was burned, and that an investigation is ongoing.

FEMA doesn't investigate building collapses. Where did you get the idea that they did?

a reply to: samkent

I've already told you about this.. they were involved in some ways.


www.fema.gov...

It so happened--surprise, surprise--that FEMA was conducting a training exercise in lower Manhattan in the same time period that the attacks happened. It was called Tripod. The good thing about that is that one of the FEMA photographers took a bunch of pictures showing, among other things, how the damage observed was impossible to have been caused by office fires. That photographer is now living in South America in fear of his life.

How convenient that both FEMA and the Pentagon were conducting "training exercises" that day.

Kader Toy Factory Fire

At about 4pm on May 10th, 1993, a small fire was discovered on the first floor of part of the E-shaped building. Workers were instructed to keep working as the fire was thought to be minor. The fire alarm in this building did not sound.

The building was reinforced with un-insulated steel girders which quickly weakened and collapsed. This part of the building was dedicated to the storage of finished products and the fire spread quickly. Other parts of the factory were full of raw materials which also burnt very fast... Fire-fighters arrived at the factory at about 4:40pm, to find Building One about to collapse.

The Kader buildings,...collapsed relatively early in the fire because their structural steel supports lacked the fireproofing that would have allowed them to maintain their strength when exposed to high temperatures.

A post-fire review of the debris at the Kader site showed no indication that any of the steel members had been fireproofed.

WTC Building #7, a 47-story high-rise not hit by an airplane, exhibited all the characteristics of classic controlled demolition with explosives:

WTC 7 suffered massive impact damage from debris during the collapse of WTC 1.

Boyle: So we go there and on the north and east side of 7 it didn’t look like there was any damage at all, but then you looked on the south side of 7 there had to be a hole 20 stories tall in the building, with fire on several floors. Debris was falling down on the building and it didn’t look good.

www.debunking911.com...

This video proves that demolition explosions did not bring down WTC 7 because no demolition explosions are heard as WTC 7 collapsed.

In regard to explosions, no evidence of explosives was ever found at ground zero.

Do you honestly believe that? I mean, can you honestly believe that? It's not like the people responsible for examining ground zero would have had anything to gain by hiding that, if they found any evidence. Any examination put forth by the government or government institute is inherently untrustworthy when it comes to that sort of stuff.

WTC 7 suffered massive impact damage from debris during the collapse of WTC 1.

Just so you folks don't get mislead by sky guy's dis/mis info let me quote NIST..

WTC 7 was severely damaged by debris from WTC 1, it wasn't just the fires that made it collapse.

Although NIST considered this hypothesis , it eventually ruled it out stating, "Other than initiating the fires in WTC 7, the damage from the debris from WTC 1 had little effect on initiating the collapse of WTC 7..

So There you have it, even NIST said it was not a factor..

Yes he does, but what he will fail to tell you is that they did not look for evidence of explosives, therefor none were found..

I think that was in response to thermite. NIST didn't test for thermite because it "was unlikely any would be found." which kind of shows the attitude they were going into the whole affair with...

a reply to: Eilasvaleleyn

Absolutely!! No doubt about it!!

Explosives make a lot of noise and in each WTC video, there is no sound of demolition explosions. Add to the fact that there was no way that anyone could have pre-weakened the steel structures, firewalls and stairwells, which is required, without creating a lot of noise and an environmental hazard. Just placing explosives in a steel frame building is not going to bring down that building, which was evident in 1993 when a huge bomb failed to bring down WTC 1 in 1993, which left its steel columns standing within that huge bomb crater.

It's not like the people responsible for examining ground zero would have had anything to gain by hiding that, if they found any evidence.

First of all, you have to have a reason to check for explosives, and there was no reason because no demolition explosions were observed nor heard as WTC 1, WTC 2, and WTC 7 collapsed and no demolition explosions were detected by seismic monitors in the area and furthermore, there was no evidence of demolition explosives found in dust samples taken after 9/11.

There was no need to examine the WTC steel for explosives because seismic data from multiple seismic sources detected no evidence of explosives and if explosives had been properly placed on the steel columns, the explosives would have sent shock signals through structural steel that they were attached to and into the ground where the signals would have been detected by the seismic monitors, and once again, no such signals were detected in which case, it makes no sense to examine the structural steel of the WTC buildings for explosives when no such evidence existed in the first place.

Let's do a recap.

1. No demolition explosions observed as the WTC buildings collapsed

2. No demolition explosions heard as the WTC buildings collapsed

3. No demolition explosions detected by multiple seismic monitors

4. No evidence of explosives found in dust samples examined by the RJ Lee Group.

In other words, there is no case for the use of demolition explosives at ground zero.

Now, let's take a look at the rest of the story.

The Collapse of WTC 7

After the North Tower collapsed, some firefighters entered 7 World Trade Center to search the building. They attempted to extinguish small pockets of fire, but low water pressure hindered their efforts. Over the course of the day, fires burned out of control on several floors of 7 World Trade Center; the flames visible on the east side of the building.

During the afternoon, fire was also seen on floors 6–10, 13–14, 19–22, and 29–30. In particular, the fires on floors 7 through 9 and 11 through 13 continued to burn out of control during the afternoon. At approximately 2:00 pm, firefighters noticed a bulge in the southwest corner of 7 World Trade Center between the 10th and 13th floors, a sign that the building was unstable and might collapse.

During the afternoon, firefighters also heard creaking sounds coming from the building. Around 3:30 pm, FDNY Chief Daniel A. Nigro decided to halt rescue operations, surface removal, and searches along the surface of the debris near 7 World Trade Center and evacuate the area due to concerns for the safety of personnel. According to FEMA, the building started to collapse at 5:20:33 pm EDT when the east mechanical penthouse started crumbling,

NIST WTC 7 Report

5. How did the fires cause WTC 7 to collapse?

The heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. The failure of this structural column then initiated a fire-induced progressive collapse of the entire building.

According to the report's probable collapse sequence, heat from the uncontrolled fires caused thermal expansion of the steel beams on the lower floors of the east side of WTC 7, damaging the floor framing on multiple floors.

Eventually, a girder on Floor 13 lost its connection to a critical column, Column 79, that provided support for the long floor spans on the east side of the building (see Diagram 1). The displaced girder and other local fire-induced damage caused Floor 13 to collapse, beginning a cascade of floor failures down to the 5th floor. Many of these floors had already been at least partially weakened by the fires in the vicinity of Column 79. This collapse of floors left Column 79 insufficiently supported in the east-west direction over nine stories.

www.nist.gov...

Nothing there about demolition explosions as responsible for the collapse of WTC 7 because the creaking noises and the bulge was evidence of internal structural failure.

According to some, but the official stance is that NIST never actually investigated as far as I'm aware. They didn't actually look for any explanation beyond the fire-induced hypothesis.

Let's do a recap.

Why did NIST not Consider a “Controlled Demolition

NIST conducted an extremely thorough three-year investigation into what caused the WTC towers to collapse, as explained in NIST’s dedicated Web site, wtc.nist.gov.... This included consideration of a number of hypotheses for the collapses of the towers.

Some 200 technical experts—including about 85 career NIST experts and 125 leading experts from the private sector and academia—reviewed tens of thousands of documents, interviewed more than 1,000 people, reviewed 7,000 segments of video footage and 7,000 photographs, analyzed 236 pieces of steel from the wreckage, performed laboratory tests and sophisticated computer simulations of the sequence of events that occurred from the moment the aircraft struck the towers until they began to collapse.

Based on this comprehensive investigation, NIST concluded that the WTC towers collapsed because: (1) the impact of the planes severed and damaged support columns, dislodged fireproofing insulation coating the steel floor trusses and steel columns, and widely dispersed jet fuel over multiple floors; and (2) the subsequent unusually large jet-fuel ignited multi-floor fires (which reached temperatures as high as 1,000 degrees Celsius) significantly weakened the floors and columns with dislodged fireproofing to the point where floors sagged and pulled inward on the perimeter columns. This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers.

Both photographic and video evidence—as well as accounts from the New York Police Department aviation unit during a half-hour period prior to collapse—support this sequence for each tower.

www.webcitation.org...

To sum it up, there was never evidence for demolition explosives.

a reply to: wildb

You are aware thermite was found according to some right? Going to post the link, give me a minute..

That is false. Let's hear it from the folks whose dust samples have debunked claims that evidence of explosives and thermite was found in their dust samples.

RJ Lee Group Dust Sample Report

RJ Lee Group Confirms: No Evidence of Explosives and Thermite in its Dust Samples

No Thermite Found

The R.J. Lee Company did a 2003 study on the dust and didn't find thermitic material. Other sampling of the pulverized dust by United States Geological Survey and RJ Lee did not report any evidence of thermite or explosives. It has been theorized the "thermite material" found was primer paint.

No evidence has ever been found of explosive charges and there are no recordings of a series of very loud explosions that would have been expected with controlled demolition. Furthermore, there is an alternative explanation for the "thermitic material" the sceptical scientists found in the dust - it is just a type of primer paint. It's calculated 1,200,000 tonnes of building materials were pulverised at the World Trade Center and most minerals are present in the dust (not necessarily in a large quantity).

More extensive sampling of the dust has not found any evidence of thermite or explosives, says a report from the US Geological Survey.

The RJ Group

The RJ Lee Group report considers samples taken several months after the collapses, and it is certain that torch-cutting of steel beams as part of the cleanup process contributed some, if not all, of the spherules seen in these samples.

They could not pack enough thermite in the WTC buildings to bring them down and not attract a lot of attention. After all, 1/2 tons of thermite failed to cut a vehicle in two.

Why don't you consider that preceding the attacks the World Trade Centre was already in contact with a conspiracy control model pre dating the outcome of the building collapse.....mind control and mind change for different choices involving saving the economy.

The model for mind control and mind contact studied by, through and because of UFO activity....nuclear transmitted messages in atmospheric light and sound and these messages studied to be the contact for the human mind and human chemical change....by evidence of those attacked, to conclude a use for mind contact and change of mind/decision making.

The study of mind control a CIA operative, taken from Russian studies of psychics...etc.

If an economy was failing and the choices made by the Government caused it to fail...and you cannot control the human choice, but can cause it to consider other information, then this would be the model used.

The UFO witnessed around the Towers, a year before. This was also considered to be discredited.
The UFO as a nuclear (matter) transmitted message used by the operatives for mind contact and mind control of the World Trade practices...human choice.

The nuclear transmitted message used also alters the condition of metal/stone, for that is what the nuclear sound signal is used for....converting the stone dust into a fuel.

The human condition of receiving the UFO attacks/alien fake/false artificial spirits involve phenomena itself, which involves changed "magnetism" and also the ability to hear relayed speaking. Houses crack/explode and a huge increase of paranormal noises heard in the interactions. Nuclear sound causes changes to the fusion of matter.....weakening the matter itself and hence would have weakened the structure of the building material.

This is all evidence to the condition of the building fall out, which could not conclusively be described as an actual caused bombing, or supply evidence to a bomb blast....but it does supply its own evidence to a weakening of the building structure itself.

Why has earth stone suddenly began to collapse into sink holes after a long use of nuclear fuel converting at the ground level?

If anyone truly reviewed information of the conspiracy, this would be the obvious cause of the building collapse, as a change of natural fusion/bonds due to the continued relayed use of the contact relay. Which actually involves the total conspiracy itself regarding why the World Trade Center collapse was considered to be caused by America itself.

These forms of conspiracies are not simply implied to a lack of factual information. It is how the information is thought about that should be considered, as to what evidence actually happened as the informed status regarding this type of conspiracy.
