Part One of My Video Text
Hi all,
This is a rough draft of the text of Part One of my upcoming video. Much more to come. No visual elements in this text, but you can at least see where slides and video will be added. When it says FACE that's when the camera goes back on my face. Otherwise, much of it is the pix and videos. I have a general introduction but here's where the science begins. Any comments?
BACK TO MY FACE:
Here’s an accusation that I’m afraid applies to all of us. MIT Prof Thomas Eagar was complaining about 9/11 truth movement and remarked,
"These people use the 'reverse scientific method.' They determine what happened, throw out all the data that doesn't fit their conclusion, and then hail their findings as the only possible conclusion."
It’s a human tendency we all share. Richard Gage also talks about scientific method, repeatable experiments, changing hypotheses. And he attacks NIST for admitting they never looked for explosives. “How can you find what you are not looking for?” I brought that question to Michael Newman at NIST and he replied, “We followed the evidence.” I asked, if you had found detonator materials or other physical evidence of controlled demolition, would you have looked for evidence of controlled demolition? “Of course!” he said. He also did not look for mini-nukes, post Star-Wars energy rays, aliens, missiles, holograms or other alleged sources of the World Trade Center collapses. To Richard Gage, this is reverse scientific method. To NIST it was following evidence and not finding any evidence of controlled demolition in the debris. There is an easy solution to this standoff, but it is not being done by the 911 Truth activists. I will discuss when we talk about the thermitic materials allegedly in the dust.
I tried hard to look at both sides and I’ve sometimes wondered if Richard Gage is right. I’ve read dozens of expert explanations, then watched several 9/11 videos, dug up original complete eyewitness interviews, joined an online science Q&A club, read 1000 pages of the NIST report and asked some really tough questions directly of NIST, chemist Kevin Ryan and former controlled demolition employee Tom Sullivan. I’ve asked over a dozen technically trained people to try to answer these questions. One of these is a certified structural engineer from New York who believes in 911 government complicity not controlled demolition. I’ve also talked with experts who have studied 911, including scientists of all kinds, metallurgists, an NY 911 fire engine chief, other structural engineers, chemists, controlled demolition experts, a dust analyst, architects, and a range of other people with expertise and direct 911 experience. I’ve joined several physics and 911 chat rooms. Outside of the 911 Truth movement, I have yet to meet a single scientifically trained person who believes in controlled demolition of the World Trade Center Buildings or any of the major scientific assertions that are used to support such a theory.
Here is an explanation of how the Twin Towers of the World Trade Center collapsed on that terrible day. BACK TO SLIDES: 8 Text
For starters, Why a building is being created tells us a lot about its structure.
9 (PYRAMID SLIDE). Egyptian Pharoahs wanted immortal home, architects said OK boss. Several thousand years later the pyramids still stand.
10. (Picture of standing buildings). Capitalists are motivated to minimize expense and maximize profit. Fulfill the building code; make Renters feel safe.
But, boss wants office space to rent. 11. (Map of WTC buildings)
So the young, innovative engineers and architects designed skyscrapers with Hundreds of slender, hollow steel support columns around the outside and a strong steel core but without the usual heavy concrete support. Instead, they sprayed on fireproofing for the steel supports to lighten the structure. They built in structural redundancies to hold three times the buildings’ static weight... not five times as Richard Gage asserts... with hat-shaped trusses in the top of the building to shift loads to other columns at almost the speed of sound in the event of a structural crisis. By the way we’ll see that falling loads quickly exceed even 5 times the structural capacity of any building. The towers would be very resilient and able to withstand major hurricanes and even jet plane crashes as long as there was no burning fuel. As Time Magazine reported in the early 70s, the next generation of skyscrapers could rise higher than ever because of their brilliant lightweight structure. Young architects like Leslie Robertson seemed to defy gravity, soaring to new building heights while creating exciting open-air designs with 72 foot long trusses, longer than ever before used. As Richard Gage points out in his video, “the 208' x 208' open floor plan and the long spans departs from the high rise tradition of a dense grid of steel.” Richard Gage also pointed out that “Trusses were bolted to perimeter columns and core columns with 5/8 inch bolts.” Frank de Martini, quoted in Blueprint for Truth, compared the perimeter structure to the screen on a door which easily survives being punctured. Tragically, he died on 9/11 and is unable to offer us his hindsight perspective now that the buildings have collapsed.
The simple square building design meant that many of the steel columns, trusses and facades were prefabricated and standardized. The buildings were 95% air by volume, 220 acres of floor space in two towers, one full acre per floor, mostly rentable space. They made them beautiful in a modern way....Alcoa aluminum still boasts about “ T, a shiny lightweight aluminum alloy” that was the outside facade of the towers and helped attract renters.
12 Slide of defective fireproofing In 1993 there was a terrorist bombing of the World Trade Center. After the 1993 bombing, inspectors found fireproofing to be deficient. By 911, replacement was completed on only 18 floors in 1 WTC, and on 13 floors in 2 WTC. The deficient fireproofing probably didn’t matter, as much of it in the crash zone was stripped of by the planes anyway.
13 Truss Seat SLIDE. The long trusses were designed to maximize open space and were up to 72 feet long. They sat on these truss seats and were fastened by 5/8 inch bolts.
So here’s a collapse scenario:
Number 1: On 9/11, Eduardo Kausel, at MIT writes:
14 (SLIDE of plane on its way) “The North Tower was hit at 8:46 above the 96th floor by a Boeing 767 flying at (429 mph)... The South Tower was hit at 9:03 above the 80th floor by another 767 flying at (503 mph).” ..notice size of the plane relative to the one-acre building... it’s a huge jet, covering 60% of the width of the building, it weighs 282,000 pounds, and it’s going over 500 mph!
15 SLIDE of crash/explosion Forensic analyst Jonathan Barnett, who was quoted in Blueprint for Truth but doesn’t believe in controlled demolition, said the planes hit the towers at 30 and 45 degrees respectively, causing damage to the maximum possible floors, stripping the painted-on fire insulation and cutting off the water sprinkler pipes. NIST says 43 of 47 core columns were stripped of insulation plus 60,000 sq feet of floor. The plane hitting the south tower impacted with 50% more energy because of its higher speed, and went in almost horizontally, so more of the aircraft passed straight through the offices, hitting the core directly, without slamming through as many concrete floors.
16 Slide Picture 30 seconds later immediate mechanical damage: F. R. Greening says the vertical collapse safety factor was reduced from 3 to 2 when 60% of the columns on the damaged side were destroyed. The compression wave from the impact visibly damaged the structural integrity of four floors below the crash. Shifting the load to the surviving beams created an “eccentric load,” so the pressures on the remaining structures were vertical (as always) and lateral. Compression waves from the collisions torqued the building. Escapees reported wall cracks and doors jammed shut well below the crash site, evidence of structural weakening. NIST reports that people were knocked down and furniture flew around many floors below the crash.
This is the mechanical damage.
17 Number 4: With the fires, the real destruction begins. According to NIST, some of the jet fuel exploded immediately, and fires spread to all four faces within 15 minutes. Soon smoke is pouring out of the vent from the 109th floor. Suicide leaps occur by the hundreds as the smoke chokes people on the even the top floors. Over 1000 windows break out as the fire spreads, providing over 12,000 sq feet of fire ventilation.
18 (SLIDE Purdue computer simulation of crash inside) Eduardo Kausel said: “The ensuing fireball set the buildings ablaze in a virtually uncontrollable, fierce fire... The intense fire heated the structural steel elements well beyond the thermal limit of some (750°F), which caused the steel to lose both its stiffness and resistance.” Leslie Robertson is a designer of the World Trade Center and was quoted in Blueprint for Truth about the fires. As I mentioned, he dismisses the controlled demolition theory. He said, “With the 707 the fuel load was not considered in the design. There was no fire suppression system that could even begin to deal with that... Little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance.” So the buildings were originally designed to withstand the physical impact of a plane crash, but their model did not include the destructive power of the burning jet fuel!
Purdue University spent thousands of hours feeding in precise technical specifications to create this 2009 computer simulation of the first second of what the mechanical damage and exploding fire would have looked like in the building: It shows the plane’s destructive power and confirms the major findings of the NIST Report.
19. SLIDE OF MORE REASONS WHEN READY: 90,850 litres of viscous dense “blue gunk” burning jet fuel created massive conflagrations. NIST says some of that fuel sprayed on some of the furniture and the tens of thousands of filing cabinets and cubicles, and much of the rest coursed down the elevator shafts, heating and softening the vertical core beams, blowing out doors and walls all the way to the basement, exploding on the 77th and 22nd floors of the North Tower, and on the west side lobby, and triggering a fatal fireball on the concourse. The energy of the explosions radiated with equal ferocity forward, backward, left, right, up, down, diagonally, and most of this explosive energy was absorbed by the building itself. What we see outside is actually only one direction of the explosive energy.
NIST Tower Collapse Sequence: NIST says These fires 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.
20. Number 5. (Steel Slide) is this consistent with the properties of steel? It melts at around 27500. Office fires can exceed 15000 F, but Colin Bailey says temperatures increase over time, and can get as high as 20120. Jet fuel burns at 800-15000. At 11000-1200o, steel loses 50% of its integrity. The thermal limit of structural steel is 750o. Dr. Allen Firmage asserts that steel girders are bent at 800-10000 , to create curved frames for bridges. steeluniversity.org explains that steel begins to lose its resistance to distortion at 5720. At azom.com, they say steel expands in length at temperatures as low as 3000.
NIST says pockets of the WTC fires reached 18000. Thomas Eager asserts that with limited oxygen, the fire temperature topped out at around 1400o. Corus Construction Co’s website says that steel is usually only 100-200 degrees cooler than the surrounding air.
22 (Huge fire slide)
Steel was up to over 1900 degrees in local “hot spots” especially in the far end of the South Tower where the jet pushed tons of debris into a pile. Other places never got over 500 degrees. According to Thomas Eagar who is quoted in Blueprint for Truth but opposes the Controlled Demolition theory, localized hot temperatures weakened some steel, and the temperature differential is also helped destroy the structural integrity of the beams.
“No normal office fires would fill 4,000 square meters of floor space in seconds.... Usually, the fire would take up to an hour to spread... across... the building. This was a very large and rapidly progressing fire.” NIST says that At 9:37 a.m., a 105th floor occupant reported that floors beneath him "in the 90-something floor" had collapsed.
Number 6: (NIST picture with lattice) By 10:23 am in WTC I, the sagging of the steel girders caused walls to bow inward 55 inches.. Above the impact zone, the entire building tilted south. Here are two pictures, taken about 50 minutes apart. (See sag picture) This has been called a utility cable; NIST calls it a sagging floor. (See video of beams sagging and snapping) In this simulation the long support beams functioned as one unit across large areas. They gradually sagged downward enough to help cause the inward bowing of the outer columns; varying degrees of fire damage on all four sides of the building caused irregular stresses everywhere. Somehow the 5/8 inch bolts held fast as the building bowed inward, in spite of the fact that many were weakened by heat. NIST says they went from being able to hold 36,000 pounds each down to about 8,000 pounds when heated to 1400 degrees.
SLIDE: BOWING ONE MINUTE BEFORE COLLAPSE. By the time collapse was imminent, bowing was extreme.
SLIDE: MORE REASONS FOR NATURAL COLLAPSE
911 a SLIDE: PICTURE OF ANTENNA and smoke:
Near the end, smoke was billowing through the top of the building as the fire and smoke spread upwards. Richard Gage said “the fires were diminishing severely,” but in fact they had grown from three floors to at least fourteen floors in less than an hour. At the critical moment of failure, three outside walls were nearing capacity but still providing support. The core, on the other hand, had compressed due to broken columns and creeping behavior, and the hat truss that connected the perimeter walls to the core was partially suspending the core.
The weak south wall buckled first and was momentarily supported by the hat truss, which buckled in the center first, causing the “antenna drop” seen by FEMA and others. As the building began its collapse, air pressure pushed smoke upwards and out the sides. Richard called this “evidence of explosions on top of Building 1,” but if there had been 4500 degree thermites at the very top of the building, then no one could have walked on the debris pile.
In addition, in a classic controlled demolitions, no smoke comes out the top...
- We know from 911 calls that people in the upper floors were severely suffering from smoke inhalation. Is that also only explicable with explosives, or would that not rather more likely indicate that hot smoke can rise through a structure?
Look at the movement of the smoke in absolute terms, rather than relative to the falling towers, and note that the smoke and dust left behind by the collapses had no significant upward velocity component.
Or as one scientist put it, “he actually said "smoke rises" and used it as proof of a CD?” ...I wonder if Richard is trying to say they took the towers down using demolition charges on the roof. - I also don’t understand why smoke ejection at the top is indicative of explosions?”
The building that had twice as much weight above the crash site collapsed twice as quickly, not surprising in a natural collapse scenario.
NIST said that At 10:20 a.m., the police aviation unit reported that "the top of the tower might be leaning," and a minute later reported that the WTC I North Tower, "is buckling on the southwest corner and leaning to the south". At 10:28 a.m., they reported that "the roof is going to come down very shortly." The North Tower collapsed at 10:28 a.m..
Number 9: WTC II South Tower
There were a few differences. The South Tower was hit at 9:03 am, causing building to sway 27 inches back and forth. The off center impact twisted the upper part counterclockwise. 911 calls reported falling ceiling tiles, collapsed walls, jet fuel smells.
The top section tilted towards the face that had buckled, behaving largely as a solid block separate from the rest of the building. It fell at least one story in freefall and impacted the lower sections with a force equivalent to over thirty times its own weight. This was sufficient to buckle the columns of the story immediately below it; the block then fell freely through the distance of another story.
Richard reported that firefighters witnessed sounds and flashes of explosions, orange and red flashes all around the building,” which is true. BELLOWS SLIDE At the onset of both collapses, ½ million cubic feet of air per floor was being pushed down onto the fires, creating a monumental “bellows effect,” literally stoking the fires and quickly creating a massive “ring of fire” around the perimeter of the collapse zone. That is a much more plausible explanation for the fire’s sudden growth. If it were from controlled demolition, similar rings of fire would have been visible on dozens of other floors during the collapse, and they were not.
SLIDE OF THIS: .NIST says “no building in the United States has ever been subjected to the massive structural damage and concurrent multi-floor fires that the towers experienced on Sept. 11.”
SLIDE SOUTH 13 story FACADE Number 11: NIST predicted many breaks in the support columns every one to three stories especially at the weaker welded connections, but many randomly damaged steel supports were much smaller, and others much bigger, like this 13-story high facade, which would have been pulverized by a controlled demolition.
There has not been a single published, peer-reviewed paper disputing the fundamentals of this collapse theory – not from any person in any department, in any field, in any country in the world. On the other hand, there have been several published results in general support of this collapse hypothesis. This is part of the reason why NIST did not consider the entire duration of the collapses. Early results from engineers and scientists indicated that, once the upper stories began to fall, the complete collapse of the structure was not in doubt, and there was no credible result to the contrary. There still are none.
The National Institute of Standards and Technology issued their technical findings on the collapses of these buildings to determine causes and make recommendations for new Building and Fire Code standards. The National Fire Protection Association and the International Code Council both took NIST’s recommendations and redesigned their templates for building and fire codes, and unlike Richard Gage I believe those revisions will save lives. The likely natural collapse scenario you have just heard is compiled from my research with NIST as well as a host of other scientific sources. In the next section of Blueprint for Truth Reconsidered, we will examine some of Richard Gage’s objections to this Natural Collapse theory.
