Proof Of Controlled Demolition At The WTC
by Jerry Russell, Ph.D.
Steel frame towers are built very strongly. They need to withstand the pressure of gale-force winds, the violent rocking motion of earthquakes, and the ravages of time. For this reason, they are almost impossible to destroy.
Airplane strikes do not destroy skysc****rs. A bomber strike to the Empire State Building during World War II did not harm that building. The World Trade Center towers were designed to survive a strike by a Boeing 707. The 767 is more massive, so the building was stressed near its design limits. But if a failure had occurred at that moment, it would have been at the point of highest levered stress, near the base of the tower, and the tower would have fallen over like a giant tree in a forest windstorm. That, of course, did not happen.
Fires do not destroy skysc****rs. Never in the history of steel frame structures has a single one been destroyed by fire.
How to destroy a skysc****r. So, how do you destroy a skysc****r? Suppose you need the vacant land to build another one, for example.
A nuclear bomb is very effective, but it can be difficult to get permits from the city.
An early invention was the wrecking ball. A huge lump of steel and lead is swung from a massive chain at high speed. With the benefit of momentum, it is able to bend or break a few girders at a time. But it would be a hopeless task to destroy a tower the size of the World Trade Center, using a wrecking ball.
The most effective, cleanest, safest way to destroy a skysc****r is known as controlled demolition. The trick is to distribute explosives at key points throughout the structure. The explosives are detonated simultaneously, destroying the integrity of the steel frame at key points, such that no part of the building is supported against the force of gravity. The entire mass is pulled swiftly to earth, where gravity does the work of pounding the structure into tiny fragments of steel and concrete. The gravitational potential energy of the structure is converted smoothly and uniformly into kinetic energy, and then is available very efficiently to pulverize the fragments of the building as they impact against the unyielding earth. Controlled demolitions have a striking and characteristic appearance of smooth, flowing collapse.
As your eyes will tell you, the World Trade Center collapses looked like controlled demolitions. Here's the proof.
The proof. According to the law of gravity, it is possible to calculate the time it takes for an object to fall a given distance. The equation is H=(1/2)at2, where H is the height, a is the acceleration of gravity (10 meters per second squared) and t is time in seconds. Plug in the height of the building at 1350 feet (411 meters) and we get 9 seconds. That is just about the length of time it took for the very top of the World Trade Center to fall to the street below. According to all reports, the whole thing was over in just about ten seconds.
It is as if the entire building were falling straight down through thin air. As if the entire solid structure below, the strong part which had not been burned or sliced or harmed in any significant way, just disappeared into nothingness. Yet this (within a small tolerance) is what we would expect to find if there had been a controlled demolition, because the explosions below really do leave the upper stories completely unsupported. Like the Road Runner after he runs off the edge of the cliff, the entire building pauses a moment, then goes straight down.
Any kind of viscous process or friction process should have slowed the whole thing down. Like dropping a lead ball into a vat of molasses, or dropping a feather into the air, gravitational acceleration cannot achieve its full effect if it is fighting any opposing force. In the case of the World Trade Center, the intact building below should have at least braked the fall of the upper stories. This did not happen. There was no measurable friction at all.
This proves controlled demolition.
We have been lied to. We have been lied to about this, at multiple levels. The first lie was that the load of fuel from the aircraft was the cause of structural failure. No kerosene fire can burn hot enough to melt steel. In point of fact, most of the fuel in the jets was contained in their wing tanks. The thin aluminum of the tanks was pierced or stripped as the airplanes penetrated the walls of the towers, and the result was the huge fireball which was seen on national TV, where most of this fuel was burned.
A hot, vigorous fire would have blown out many windows in the building and would have burned a red or white color. This was not what happened. The fire in the World Trade Center was an ordinary smoldering office fire.
But let's suppose that the fire was hot enough to melt steel. What would have happened in that case? Before it breaks, hot steel begins to bend. This redistributes the forces in the structure and puts elastic stress on those parts that are still cool. The process is asymmetric, so that the structure should visibly bend before breaking. But of course, no steel skysc****r has even bent over in a fire.
Let's suppose the structure were sufficiently weakened that it did fail catastrophically near the point of the airplane strike. In this case, the intact structure below would exert an upward force on the base of the upper story portion of the building (the part that has been broken loose), while any asymmetry would allow the force of gravity to work uninhibited on the tip of the skysc****r. Thus, the top section of the skysc****r would tip and fall sideways.

Controlled demolition brought down Twin Towers says Bush insider by Greg Szymanski
A former chief economist in the Labor Department during President Bush’s first term now believes the official story about the collapse of the WTC is "bogus," saying it is more likely that a controlled demolition destroyed the Twin Towers and adjacent Building No. 7.
"If demolition destroyed three steel skysc****rs at the World Trade Center on 9/11, then the case for an ‘inside job’ and a government attack on America would be compelling," said Morgan Reynolds, Ph.D, a former member of the Bush team who also served as director of the Criminal Justice Center at the National Center for Policy Analysis headquartered in Dallas, TX.
Reynolds, now a professor emeritus at Texas A&M University, also believes it’s "next to impossible" that 19 Arab *********s alone outfoxed the mighty U.S. military, adding that the scientific conclusions about the WTC collapse may hold the key to the entire mysterious plot behind 9/11.
"It is hard to exaggerate the importance of a scientific debate over the cause(s) of the collapse of the twin towers and Building 7," said Reynolds recently from his offices at Texas A&M. "If the official wisdom on the collapses is wrong, as I believe it is, then policy based on such erroneous engineering analysis is not likely to be correct, either. The government’s collapse theory is highly vulnerable on its own terms. Only professional demolition appears to account for the full range of facts associated with the collapse of the three buildings.
"More importantly, momentous political and social consequences would follow if impartial observers concluded that professionals imploded the WTC. Meanwhile, the job of scientists, engineers and impartial researchers everywhere is to get the scientific and engineering analysis of 9/11 right."
However, Reynolds said "getting it right in today’s security state" remains challenging because he claims explosives and structural experts have been intimidated by government agents while attempting to conduct objective analyses of buildings that collapsed on 9/11.
From the beginning, the Bush administration claimed that burning jet fuel caused the collapse of the towers. Although many independent investigators have disagreed, they have been hard pressed to disprove the government theory since most of the evidence was removed by FEMA prior to independent investigation.
Critics claim the Bush administration has tried to cover-up the evidence and the recent 9/11 Commission has failed to address the major evidence contradicting the official version of events for that tragic day.
Some facts demonstrating the flaws in the government "jet fuel" theory include:
— Photos showing people walking around in the hole in the North Tower where 10,000 gallons of jet fuel were supposedly burning.
—When the South Tower was hit, most of the North Tower’s flames had already vanished, burning for only 16 minutes, making it relatively easy to contain and control without a total collapse.
—The fire did not grow over time, probably because it quickly ran out of fuel and was suffocating, indicating without added explosive devices the fires could have been easily controlled.
—FDNY fire fighters still remain under a tight government gag order to not discuss the explosions they heard, felt and saw. FAA personnel are also under a similar 9/11 gag order.
—Even the flawed 9/11 Commission Report acknowledges that "none of the [fire] chiefs present believed that a total collapse of either tower was possible."
— Fire had never before caused steel-frame buildings to collapse except for the three buildings on 9/11, nor has fire collapsed any steel high rise since 9/11.
— The fires, especially in the South Tower and WTC-7, were relatively small.
— WTC-7 was unharmed by an airplane and had only minor fires on the seventh and twelfth floors of this 47-story steel building yet it collapsed in less than 10 seconds.
— WTC-5 and WTC-6 had raging fires but did not collapse despite much thinner steel beams.
— In a PBS documentary, Larry Silverstein, the WTC leaseholder, told the fire department commander on 9/11 about WTC-7 that "may be the smartest thing to do is pull it," slang for demolish it.
— It’s difficult if not impossible for hydrocarbon fires like those fed by jet fuel (kerosene) to raise the temperature of steel close to melting.
Despite the numerous holes in the government story, the Bush administration has brushed aside or basically ignored any and all critics. Mainstream experts, speaking for the administration, offer a theory essentially arguing that an airplane impact weakened each structure and an intense fire thermally weakened structural components, causing buckling failures while allowing the upper floors to pancake onto the floors below.
One who supports the official account is Thomas Eager, professor of materials engineering and engineering systems at MIT. He argues that the collapse occurred by the extreme heat from the fires, causing the loss of load-bearing capacity on the structural frame.
Eagar points out the steel in the towers could have collapsed only if heated to the point where it "lost 80 percent of its strength," or around 1,300 degrees Fahrenheit. Critics claim his theory is flawed since the fires did not appear to be intense and widespread enough to reach such high temperatures.
Other experts supporting the official story claim the impact of the airplanes, not the heat, weakened the entire structural system of the towers, but critics contend that the beams on floors 94-98 did not appear severely weakened, much less the entire structural system.

Team Hopkins made Tito re-wrapped cause it was illegal.
Garcia wanted Pac to re-wrap cause he caught them inserting plaster inserts in his wraps. The corrupt Texas commission refused (at DelaHoya and Arum's pre-planned order, which is why they had rappers singing before the fight cause they all know it would take a while to convince Margo to accept the FIXED FIGHT, and now with Pac having loaded gloves, if Margo wants re-licensing) and thats why Margarito drank a powdered liquid, cause he was trying to "level out the playing field" against a steroid cheating Pacman that had loaded wraps and was gonna hit Margo all 12 rounds cause he know Margo would not hit him hard, cause the fight was FIXED in Pac's favor, so that margo would get re-licensed.Comment

WTC 7: proof of controlled demolition
Sunday, July 15, 2007
Proof that WTC 7 was demolished professionally
(This is a summary of the argument presented here, complete with more detailed source links, including Architects and Engineers for 9/11 Truth.)
WTC 7 was the third steel-framed skysc****r that was completely destroyed on 9/11. Unlike the Twin Towers, it was not hit by a plane. Its height was 174 meters, and it had 47 floors. It was located in a block separate from the other WTC buildings, 110 meters from the closest tower. The implosion of WTC 7 is shown below (note the dropping of the penthouse).
Investigations. As this was one of the biggest building disasters in world history, the remains of the skysc****r should have been painstakingly investigated. If the building collapsed in seconds to the ground as a result of fires – as FEMA speculated in 2002 – the significance of the event for building safety, building codes, etc. is enormous. It would have been easy to properly examine the debris from the building, as it landed mostly within its own footprint. This was not done, and the physical research material was quickly removed and destroyed. According to NIST, the governmental agency that is still – well after 6.5 years from the event – trying to come up with a plausible report, “no steel was recovered from WTC 7”. This can be seen as either su****ious or absurd, and I don’t think building disasters are investigated absurdly.
The speed of destruction. WTC 7 fell into a pile of debris in approximately 6.5 seconds. The corresponding free fall time is 5.95 seconds, while an apple dropped from the roof would have taken 7 seconds to fall to the ground (Kurttila 2005; the exact time varies with the air resistance of the object). The 80 steel support pillars of the building, therefore, did not in practice resist the destruction. However, destroying the support structures throughout the floors of the 174-meter building demanded energy that would have been away from pure kinetic energy; in other words, gravitational destruction of those structures would necessarily have slowed down the collapse. No slowing down required by destruction work can have taken place within the short time it took WTC 7 to collapse. To simplify: the roof came down as if mere air (and not 47 stories) had separated it from the ground. This can only be explained by the removal of structural resistance in a controlled demolition. In controlled demolitions, the roofs of highrises typically reach the ground in a time that is slightly longer than free fall. [1]
The sudden onset and symmetry of the destruction. WTC 7 dropped suddenly straight down. This means that the 80 support pillars had to give in simultaneously. To believe that random fires on separate floors and damage to one side caused the sudden vertical collapse is to believe in a miracle (as pointed out by professor David Ray Griffin). Moreover, achieving the outcome of a controlled demolition by means of matches and damaging one side of a highrise would mean that companies specialized in controlled demolition would have to start thinking about new business ideas.
Hot debris. According to NASA’s thermal imaging, the surface temperature of the WTC 7 debris pile exceeded 700 degrees Celcius – five days after the destruction. Residual temperatures like this cannot be explained by fires or gravitational collapse. The latter can only result in a few degrees' increase in temperature.
Molten and vaporized steel. As in the case of the Twin Towers, molten steel was reportedly found in the remains of WTC 7. Some steel samples that the researchers did manage to examine were also partially vaporized. In a New York Times interview, professor Jonathan Barnett points out that fires cannot explain this. Evidently, not even these samples were kept, and NIST has ignored this finding. Molten steel can be explained by explosives but not by fires, as their temperature simply cannot rise anywhere close to the melting point of steel, let alone the temperature required by vaporization.
Expert statements. The Dutch demolition expert Danny Jowenko, who owns a demolition firm and has been in the business for 30 years, regards it as certain that WTC 7 was demolished. His view is shared by numerous architects, engineers and other demolition professionals – see Architects and Engineers for 9/11 Truth, http://www.ae911truth.org/, and this page exemplifying people with demolition expertise who question the official account.

The US Govt knew those planes were gonna hit the WTC and waited for it to happen so they can use that as the excuse to get a Trillion Dollars worth of Oil in Iraq.
Its not the 1st time the US Govt knew they were gonna be attacked.
In WW2, the US Govt (Franklin D Roosevelt) knew, ahead of time, that Japan was gonna attack pearl harbor and allowed it to happen, so they can use it as an excuse to use the H-Bombs on Japan and show off to the rest of the world the most powerfull weapon they have.
Most of these washington officials are devil-worshippers and have many washington building built to satanic building specifications, that orginated from the Freemasons.
the US dollar has a satanic symbol in the back, as the Pyramid with one eye on top, and so does the $20, $10, $5 dollar bills.Comment

This is why GOD almost buried the US in 1996 with a 6-Mile wide killer asteroid (just like what got rid of the Dinosaurs).
In the movies Armageddon, and Deep Impact, they said the asteroid was gonna hit the pacific ocean and Canada, but in real life, it was aiming for the US. But as it past the moons' orbit and was about to hit the US, GOD made it loop around the earth and to the other direction, as a warning to the US, to NOT "cross the lines" anymore.Comment
