The roofline of WTC1 (The North Tower of the World Trade Center) begins dropping with sudden onset and accelerates uniformly downward at about 64% of the acceleration of gravity (g) until it disappears into the dust. This means it is meeting resistance equal to about 36% of its weight. The implication of this, however, is that the force it is exerting on the lower section of the building is also only 36% of the weight of the falling section. This is much less than the force it would exert if it were at rest. The acceleration data thus prove that the falling top section of the building cannot be responsible for the destruction of the lower section of the building.

From that day which will 'live in infamy', came a whole host of sins, from the lies told to support the illegal and immoral invasions of Afghanistan and Iraq, to the new war unfolding against Pakistan, to the never ending drumbeat by the Zionist media to get the USA to bomb Iran to make Israel happy.
The de facto American police state was born that Fall, with Americans now being spied on, harassed and rounded up, all in the name of 'National Security.'
With Americans scared shitless and watching the skies for more hijacked planes and cowering under relentless Zionist MSM propaganda about Muslim 'boogiemen' which Wall Street used as a distraction to go on a loot, pillage and plundering spree of 401k retirement accounts and pension funds.
These are not a series of odd coincidences, but a planned and systematic looting of our wealth, freedoms and dignity.
911 Reasons why 9/11 was (probably) an inside job. PART I: 3 towers, 2 jets
Never before or after 9/11 have steel-framed skyscrapers collapsed due to fire. By Robert Bridge, RT--MORE--"
In February 2005, the 32-storey Windsor Building in the financial district of Madrid, Spain was completely engulfed by flames for 20 consecutive hours. I repeat: 20 consecutive hours. The structure did not collapse. In fact, after the fire was finally extinguished, a huge construction crane was seen perched on the roof of the building as raw testimony to the practical indestructibility of steel as a construction material.
PART I
Now compare the fire in Madrid that burned continuously for 20 hours, without compromising the structure, to two relatively low-temperature fires inside the formidably constructed WTC buildings. As the investigators would have us believe, those fires caused both structures to disappear, in mirror-image collapses, into their own footprints in less than one hour.
On October 18, 2004, an inferno gutted the top 20 floors of the 50-storey Parque Central Tower in Caracas, Venezuela. The fire burned for 17 consecutive hours, but the steel structure did not collapse.
By contrast, the fires burning inside of the World Trade Center buildings were textbook examples of oxygen-starved fires, visible by the dark gray smoke that emitted from both structures. Indeed, very few flames were visible at all. Furthermore, many tenants of the stricken buildings were able to walk down the emergency steps past the point of impact where the planes had struck.
Brian Clark, a South Tower survivor, was working in his office at Euro Brokers Inc. when, at 9:03am, United Airlines 175 crashed into the 78th Floor. Euro Brokers’ office was situated on the 84th floor, 6 storeys above the impact of the jetliner. Yet Clark, together with other fellow employees, managed to escape from the South Tower, walking down the building’s inside stairwell and past the point of impact.
“When I looked down there, I didn’t see flames,” Clark said in an interview for the film Zero. “We decided to go as far as we could until we would be stopped by flames. When we came to the 78th floor (the point of impact), there were flames licking up the other side of the wall… It wasn’t a roaring inferno. I sensed that the flames were maybe starved for oxygen right there. We kept going, and when we got to the 74th floor… normal conditions: the lights were on, and there was fresh air coming up from below.
Another indication that the WTC fires were far below the temperatures needed for a catastrophic collapse was evident by the tragic image of office workers who were filmed standing inside the gaping mouth of the airplanes’ point of entry, desperately waiting to be rescued. Indeed, much of the jet fuel that both airplanes were carrying was immediately blown out of the buildings upon impact in magnificent orange fireballs.
Kevin Ryan is a former engineer from Underwriters Laboratory (UL), a highly reputable company that was subcontracted to test the hypothesis of the National Institute of Standards and Technology (NIST) as to how the WTC towers collapsed. Ryan and his colleagues used model replicas of the WTC towers to test the ability of the structures to remain standing in the event of a fire.
“We did test the floor models in August 2004,” Ryan said, “and those tests disproved the primary theory behind the collapse of the buildings.”
“The floor models didn’t collapse in the tests,” Ryan said, “and these (models) were in furnaces in much hotter temperatures, for a longer period of time (as compared with the temperature and endurance of the fires on 9-11). Yet, they still did not collapse.”
According to Ryan, in order for NIST to get the results they were looking for, they “manipulated the test parameters. They doubled one thing, and cut something else in half. They doubled the time their computer model exposed the columns to fire – 90 minutes, as opposed to 50 minutes.”
Eventually, NIST was forced to substitute the “pancake theory” (which wrongly hypothesized that the combined force of the upper floors began a domino effect downward) for the “inward bowing theory,” which argues that the floors and walls of the WTC buildings buckled to the point where they could no longer support the weight of the structure – an equally implausible explanation for the collapses.....
David Chandler, a member of Architects and Engineers for 9/11 Truth, has created a video presentation that blows a gaping in hole in the official version of events.
Chandler focuses on the top 32 meters (equivalent to eight floors) of World Trade Center I, also known as the North Tower, which collapses and drops on top of the massive undamaged section below. It has been argued that the downward force of the upper section onto the lower section was what brought down the entire building into a mountain of dust and rubble.
Chandler tracks the rate of fall of the upper 32 meters at 64 per cent of free fall speed. In other words, once the upper structure begins to fall, the upward resistive force (that is, the undamaged section below) must be only 36 per cent of the weight of the falling section of the building, i.e. the difference in percentage (if the math seems fuzzy to some readers, you may want to find Chandler's visual models, which are easily accessible over the Internet)....
