An invasion of a country based on the 9/11 lie.
This is what the American government has done in We The Peoples name with our tax dollars.
Obama is as bad as Bush when it comes to war crimes.
Hey Obama!Stop the Massacres!
BRING OUR TROOPS HOME!
"The exhaustive effort by Craig Ranke and Aldo Marquis of Citizen Investigation Team to contact, record, document, and analyze numerous first-hand eyewitness accounts of the actual flight path of the airliner at the Pentagon on 9/11 has been long overdue, but worth waiting for. The evidence they have uncovered and compiled in their DVD "National Security Alert" deserves serious attention - particularly in light of what we now know about the explosive destruction of the three World Trade Center high-rises that day."

Here is a post from blog contributor Adam Taylor proving that the collapse rates of the WTC buildings were consistent with controlled demolition.I've read the NIST report, and the speed of fall of the buildings was the clincher for me. All of the other evidence is tirelessly debunked, but if everyone could just be educated on the irrefutable, near-free-fall of the buildings, we could make more progress.
I have an electrical engineering degree, but I still had to take Statics and Dynamics.
Here is something I posted on a science blog (of all places!) where the CT/debunking argument typically raged:
I can understand why so many are fooled on this topic. I actually had doubts (you know, anything is possible...) and I took Statics (equations of bodies at rest) and Dynamics (equations of bodies in motion) to get my degree. Then I read the NIST report on WTC7. It's a computer model, worked backwards to explain the fast fall. It's hypothetical. And they admit free-fall for a time. I had to look up the equations of free fall (with air resistance) on wikipedia and nasa.gov. The equations are specifically for acceleration without structural resistance. That means NO resistance of "upper part of building crashing into lower part, then building collapses into its footprint".
Applying this to the twin towers, all the floors below the plane impacts had resistance, had to be impacted by mass from above, for the official story to be true. "Pancaking", or the "zipper" theory require some structural failure, and that adds time. There is simply no way the twin towers collapsed by structural failure, the resistance HAD to be removed somehow. We don't know by whom, or how exactly, but there are grains of truth among the CT strawmen that are put up. Some people, like me, reluctantly admit that there's more to 9/11 than the official story because physics demands it. Others understand it intuitively, because the video of the buildings collapsing looks just like a controlled demolition, just doesn't look right for a gravitational collapse by structural failure. For us, there's no going back to the lie. I wish the official story were true. I also know this country will never be united under a lie. It's a lie of omission, because the NIST Report ends at the initiation of collapse, and doesn't explain how the floors below impact fall like they had no resistance.

Stage 1: Thermate Melts and Corrodes Core Steelwork
During Stage 1, extending from up to 10 minutes before T-0, thermate coatings on key parts of the core structure steelwork are ignited via the wireless ignition control system. The two areas attacked are: the core columns on a few floors below the crash zone, just above where most of the columns transition from box columns to wide-flange beams; and the inner portions of the hat truss that connect it to the core.
The thermal/corrosive attack on these two portions of the structure leaves the entire block of the core structure above the upper mechanical equipment floor "floating", with no major steel members to transfer its gravity loads to the lower portion of the core or to the perimeter walls: it is now supported by the web-trussed floor diaphragms. The upper core block now exerts massive inward forces on the perimeter walls due to the high degree of leverage involved in the translation of the core block's gravity loads into pulling on the perimeter walls. It is these forces that produce the inward bowing of portions of perimeter walls that NIST claims are due merely to the sagging of floor diaphragms still supported by the core.
Although an explosion is almost always accompanied by the production of a loud noise, the noise itself is not an essential element in the definition of an explosion. The generation and violent escape of gases are the primary criteria of an explosion. –NFPA 921 Guide, Chapter 18 - Explosions, 18.1
“Was the steel tested for explosives or thermite residues?”
NIST did not test for the residue of these compounds in the steel.
“Did investigators consider the possibility that an explosion caused or contributed to the collapse of WTC 7?”
Yes, this possibility was investigated carefully. NIST concluded that blast events inside the building did not occur and found no evidence supporting the existence of a blast event. In addition, no blast sounds were heard on the audio tracks of video recordings during the collapse of WTC 7 or reported by witnesses.
At this point in time, all of the military services and some DOE and academic laboratories have active R&D programs aimed at exploiting the unique properties of nanomaterials that have potential to be used in energetic formulations for advanced explosives…. nanoenergetics hold promise as useful ingredients for the thermobaric (TBX) and TBX-like weapons, particularly due to their high degree of tailorability with regards to energy release and impulse management.
The feature of ‘impulse management’ may be significant. It is possible that formulations may be chosen to have just sufficient percussive effect to achieve the desired fragmentation while minimizing the noise level.
I do not know whether the FDNY witnesses constitute a representative sample of 9/11 witnesses, but it is possible that they do. Certainly, there is no lack of testimony to explosions from those outside the FDNY, and I see no obvious reason why firefighters and medics would be more prone than others to feel that they were witnessing explosions. If they constitute a representative sample, then a minimum of 23% of all witnesses to the Towers’ collapses appear to have perceived, or thought they perceived, explosions that brought down the Towers.
Explosion sounds can be explained away. But, only after a thorough investigation. When there is this much witness testimony, evidence, and explosive use by terrorists on this very same complex, there is no excuse for refusing to test for explosive residue.
The video frame in Figure 4 of the World Trade Center North Tower taken by KTLA channel 5 news shows a "squib" -- a line of ejecting material from the tower -- right before it collapsed. Such squib ejections are driven by massive overpressure inside the building relative to the atmospheric pressure outside, and that overpressure is created by explosions. A number of squibs were observed coming from all 3 of Buildings 1, 2, and 7 a short second or 2 after each one started to collapse, and there are several websites that show photograph of them on all 3 buildings. The one displayed as Figure 4 shows ejecting material (bits of material large enough to have little air resistance) streaming out of the North Tower, which has traveled a distance from the tower in the horizontal direction, whereas the distance it has descended in the vertical direction because of gravitation pull is small.
Note the quantitative information that can be gathered from the ejection photograph in Figure 4. We can estimate that, at the front end, the ejecting plume has apparently fallen no more than roughly 3 feet (an estimate that might have up to a factor of 2 in error), whereas the horizontal distance of the front from building is about 1/3 the width of the North Tower, or about 70 feet. If we neglect air friction resistance over the length of the streamer, from fall distance s=0.5gt2, where g=32 feet/sec2 is the gravitational acceleration, we estimate 0.43 sec as the time since the front end first ejected from the building. That means that material in that squib is traveling horizontally at roughly 163 feet/sec, which means the squibs are effectively "bullets" of bits of material produced by the explosions.
Bazant, Le, Greening and Benson estimated the velocity of escaping air to be as high as 340 m/s, or 1100 fps. Of course they were trying to establish an argument for the bursts having reached the speed of sound, in order to explain away the witness testimony to explosions.
A table below summarizes some typical values of α for various material parameters.
Table: Values of α for selected material parameters
Solving (1) for v(t) by separation of variables yields the downward velocity vd and downward distance y:
(4) vd(t)= (g/α )1/2 tanh [(g α )1/2t]
(5) y(t) = (1/α) ln cosh [(g α )1/2t]
So where does this squib material hit the ground? If we take y to be the height of the ejection, we can solve the last equation for t, the time the material remains in the air. Multiply that t by the horizontal velocity vh of the squib material, and we have the horizontal distance x it travels. The equation of motion for the horizontal movement of the material is:
(6) a = dv/dt = - α v2
which solves by separation of variables, yielding:
(7) vh(t)= vo/(1 + α vot)
(8) x(t) = (1/α)
ln (1 + α vot) where vo is the velocity of initial ejection from the tower. Taking t to be the time the material remains in the air from (5) (solving for t after setting y=h) gives x(t) = xhit, the distance the material travels away from the tower. Graphs of that distance xhit versus the α for the material are shown in Figures 5 and 6 for ejections from about 1304 feet (400 meters) and 489 feet (150 m).
ROBERTSON: …I've not participated in the NIST Report directly, although of course I've read it, as have thousands of other structural engineers and other interested persons.
GR: Robertson offers no evidence to support this claim about how many people have read the NIST report. NIST published about 10,000 pages about the tower collapses. The Summary Report itself took up 248 pages plus 43 pages of front matter. Jim Hoffman’s critique of the Report notes that the Summary Report flatly contradicted some of the most important evidence presented deep in the 10,000 pages. Whistleblower Kevin Ryan calls all this the TiNRAT approach: “They’ll Never Read All This.”
Note the compound category, in which the relative numbers for the two categories of people who have read the Report are not provided. Maybe it’s three structural engineers and thousands of 9/11 skeptics! But as usual throughout the interview, we’re supposed to believe this because of who Robertson is and because he speaks confidently, rather than because of evidence and logic.
He is clearly implying that if only a few engineers have publicly challenged the official story, they are unlikely to be right. The idea of taking a majority vote of experts appeals to Americans’ sense of democratic values, but it has absolutely nothing to do with who is more likely to be right.
ROBERTSON: But the collapse mechanism of the Trade Center is as we had anticipated it would be when we first designed it. It was not – please don't misunderstand me – it was not designed to collapse. But any prudent engineer looking at the future has to think about, what are the mechanisms that cause collapse, and how to go about strengthening the building so as to minimize that circumstance. So sure, we spent time looking at that kind of event, and that which was observable from the photographs and so forth is reasonably consistent with that which we thought would be the case.
HOST: Why did it fall so straight down?
ROBERTSON: Well, that's kind of the nature of that kind of failure.
GR: This statement is reminiscent of the pre-scientific Aristotle: "It's in the nature of things to fall.” Throughout this response (continued below) Robertson says “uh” and makes other stuttering sounds and false starts more than in any other statement during the show. He misspeaks, saying that burning a sofa creates smoke capacity.
Concrete floor slabs provided vertical compartmentalization to limit fire and smoke spread between floors. -FEMA report, section 5.3.3
This is a common feature of collapses produced by explosives, as can be seen in videos of controlled demolitions of structures such as Seattle’s Kingdome and the Reading Grain Facility, which are available on the Web. The dust clouds produced at the Twin Towers differ only by being much bigger, which is what could have been predicted, given the fact that these buildings were much larger, so they would have required more powerful, and a greater number of, explosives. –Debunking 9/11 Debunking, pg. 188
Given that the Twin Towers' dust clouds behaved like pyroclastic flows, with distinct boundaries and rapidly expanding frontiers (averaging perhaps 35 feet/second on the ground for the first 30 seconds), it is doubtful that mixing with ambient air accounted for a significant fraction of their volume.
