Preface: This essay does not question whether Bin Laden and Al Qaeda attacked us on September 11, 2001, or whether Iran, Saudi Arabia or another nation-state had a hand in the attacks. It focuses solely on a peripheral issue regarding the third building which fell on that terrible day.
Former commander-in-chief President Bush said:
Let us never tolerate outrageous conspiracy theories.
Senior Bush administration officials sternly cautioned the 9/11 Commission against probing too deeply into the terrorist attacks of September 11, 2001, according to a document recently obtained by the ACLU.
The current commander-in-chief, Barack Obama, has also warned against questioning 9/11:
As anyone in the military knows, you can’t give your opinion unless you get first “permission to speak freely”.
We’re not in the military. However, I am not entirely sure that matters, given that speaking out against government policies may be considered a type of terrorism in America today.
Many hundreds of high-level military officers, intelligence officers, congressmen, legal scholars and experts have broken the commander-in-chief’s orders not to question the government’s official narrative regarding 9/11. And see this and this.
But neither Bush nor Obama has instructed us not to discuss World Trade Center Building 7. Indeed, they have never once mentioned the fact that a third building collapsed on 9/11 (and the 9/11 Commission never mentioned it either), even though that building was not hit by a plane.
And no one was killed when Building 7 collapsed. As such, discussions of why Building 7 fell does not question Al Qaeda’s responsibility for the 3,000 deaths of innocent Americans which occurred on 9/11. It doesn’t even touch on U.S. military affairs since 9/11, since no wars or anti-terror campaigns were launched to avenge anything which happened in connection with Building 7.
For these reasons, I will take the commander-in-chiefs’ silence on this subject as permission to speak freely. And the family members who lost loved ones on 9/11 want this topic discussed.
Moreover, if Building 7 collapsed for reasons other than the official explanation, that does not necessarily show nefarious intent. For example, Paul K. Trousdale – a structural engineer with decades of experience – says:
I had always thought the 3rd building was destroyed to prevent unpredictable collapse.
Here It Is
Have you ever seen Building 7 collapse? Here’s footage from several different angles:
Top Experts Say Official Explanation Makes No Sense
Numerous structural engineers – the people who know the most about office building vulnerabilities and accidents – say that the official explanation of why building 7 at the World Trade Center collapsed on 9/11 is “impossible”, “defies common logic” and “violates the law of physics”:
I agree the fire did not cause the collapse of the three buildings. The most realistic cause of the collapse is that the buildings were imploded
The collapse of WTC7 looks like it may have been the result of a controlled demolition. This should have been looked into as part of the original investigation
From videos of the collapse of building 7, the penthouse drops first prior to the collapse, and it can be noted that windows, in a vertical line, near the location of first interior column line are blown out, and reveal smoke from those explosions. This occurs in a vertical line in symmetrical fashion an equal distance in toward the center of the building from each end. When compared to controlled demolitions, one can see the similarities
Photos of the steel, evidence about how the buildings collapsed, the unexplainable collapse of WTC 7, evidence of thermite in the debris as well as several other red flags, are quite troubling indications of well planned and controlled demolition
World Trade Center 7 appears to be a controlled demolition. Buildings do not suddenly fall straight down by accident
Why would all 110 stories drop straight down to the ground in about 10 seconds, pulverizing the contents into dust and ash – twice. Why would all 47 stories of WTC 7 fall straight down to the ground in about seven seconds the same day? It was not struck by any aircraft or engulfed in any fire. An independent investigation is justified for all three collapses including the surviving steel samples and the composition of the dust
WTC 7 Building could not have collapsed as a result of internal fire and external debris. NO plane hit this building. This is the only case of a steel frame building collapsing through fire in the world. The fire on this building was small & localized therefore what is the cause?
In my view, the chances of the three buildings collapsing symmetrically into their own footprint, at freefall speed, by any other means than by controlled demolition, are so remote that there is no other plausible explanation
Near-freefall collapse violates laws of physics. Fire induced collapse is not consistent with observed collapse mode . . . .
I began having doubts about, so called, official explanations for the collapse of the WTC towers soon after the explanations surfaced. The gnawing question that lingers in my mind is: How did the structures collapse in near symmetrical fashion when the apparent precipitating causes were asymmetrical loading? The collapses defies common logic from an elementary structural engineering perspective. “If” you accept the argument that fire protection covering was damaged to such an extent that structural members in the vicinity of the aircraft impacts were exposed to abnormally high temperatures, and “if” you accept the argument that the temperatures were high enough to weaken the structural framing, that still does not explain the relatively concentric nature of the failures.
Neither of the official precipitating sources for the collapses, namely the burning aircraft, were centered within the floor plan of either tower; both aircraft were off-center when they finally came to rest within the respective buildings. This means that, given the foregoing assumptions, heating and weakening of the structural framing would have been constrained to the immediate vicinity of the burning aircraft. Heat transmission (diffusion) through the steel members would have been irregular owing to differing sizes of the individual members; and, the temperature in the members would have dropped off precipitously the further away the steel was from the flames–just as the handle on a frying pan doesn’t get hot at the same rate as the pan on the burner of the stove. These factors would have resulted in the structural framing furthest from the flames remaining intact and possessing its full structural integrity, i.e., strength and stiffness.
Structural steel is highly ductile, when subjected to compression and bending it buckles and bends long before reaching its tensile or shear capacity. Under the given assumptions, “if” the structure in the vicinity of either burning aircraft started to weaken, the superstructure above would begin to lean in the direction of the burning side. The opposite, intact, side of the building would resist toppling until the ultimate capacity of the structure was reached, at which point, a weak-link failure would undoubtedly occur. Nevertheless, the ultimate failure mode would have been a toppling of the upper floors to one side–much like the topping of a tall redwood tree–not a concentric, vertical collapse.
For this reason alone, I rejected the official explanation for the collapse of the WTC towers out of hand. Subsequent evidence supporting controlled, explosive demolition of the two buildings are more in keeping with the observed collapse modalities and only serve to validate my initial misgivings as to the causes for the structural failures
We design and analyze buildings for the overturning stability to resist the lateral loads with the combination of the gravity loads. Any tall structure failure mode would be a fall over to its side. It is impossible that heavy steel columns could collapse at the fraction of the second within each story and subsequently at each floor below.
We do not know the phenomenon of the high rise building to disintegrate internally faster than the free fall of the debris coming down from the top.
The engineering science and the law of physics simply doesn’t know such possibility. Only very sophisticated controlled demolition can achieve such result, eliminating the natural dampening effect of the structural framing huge mass that should normally stop the partial collapse. The pancake theory is a fallacy, telling us that more and more energy would be generated to accelerate the collapse. Where would such energy would be coming from?
Fire and impact were insignificant in all three buildings. Impossible for the three to collapse at free-fall speed. Laws of physics were not suspended on 9/11, unless proven otherwise
The symmetrical “collapse” due to asymmetrical damage is at odds with the principles of structural mechanics
It is virtually impossible for WTC building 7 to collapse as it did with the influence of sporadic fires. This collapse HAD to be planned
It is very suspicious that fire brought down Building 7 yet the Madrid hotel fire was still standing after 24 hours of fire. This is very suspicious to me because I design buildings for a living
The above is just a sample. Many other structural engineers have questioned the collapse of Building 7, as have numerous experts in other disciplines, including:
The collapse was too symmetrical to have been eccentrically generated. The destruction was symmetrically initiated to cause the buildings to implode as they did
Again, this essay is not questioning whether or not Al Qaeda carried out the 9/11 attacks, or even the collapse of the Twin Towers.
It is simply questioning why a third building which was never hit by a plane collapsed on 9/11.
