Oh, they'll be out in force. It might take them a day or two, but for every new revelation shining light on the 911 Inside Job they have a spin very quickly. Either they will attack the film as altered or they'll have some other spin such as the Radar was incompetent.
They won't hold water but for the Sheeple who don't want to look at reality they will grasp at any spin straw to avoid looking. They want the "Nightly Nooze" to tell them what they think.
if the identifying radar system is in real time as he claimed then it is pretty damning evidence of remote controlled drone planes. I don't know antyhing about such systems which is why i pinged the pilots. Anyway, we all know the truth but to what end ? There is more than enough evidence but most politicians, clergy, academics and influence peddlers won't look at or acknowledge any of this. And time has gone on and it's almost 10 8 yrs past.
Anyway, it's fun to expose their lies. people do know, in general, but what comes of it? we shall watch.
The government's shit is mosty likely the closest to what happened. If anything got covered up it's how little attention the Boosh's were paying when it went down...
Explain this. See how the top of the tower is tilting on an angle? Simple physics would determine that the top of the tower should have toppled over and tumbled, as there is less resistance to the air than there would be to the steel and concrete below it, thus it would have continued it's rotational movement and toppled over.
Why did it all of a sudden drop like a rock straight down through the steel and concrete rather than simply topple over as it appears ready to do in the following picture?

You mean like what happens in a controlled demolition? Well, this is different....the plane hit the building (which was specifically designed to withstand the impact of a direct hit by a plane), and the plane had fuel (no matter that the fire was limited to just a couple floors, as opposed to other towers which have also had intense fire but never collapsed)....and because of the intense flames (limited to two floors?)....the structural beams just melted.......and can't you just believe these people already?!
You forgot that it was Magickal Jet Fuel that can change properties at will and burn hotter than the sun. And they only ever made one batch of it and it was all used that day as evidenced by the fact that other skyscrapers have burned longer and fully engulfed since then, yet none of them fell. Not one. And some had burned before that day too and not one of those fell either. Steel skyscrapers just can't handle that Magickal Jet Fuel.

All this makes me question an engineer who would design a building to take the direct impact of a jet and not take into account for that jet to be able to hit the building it had to be flying and be loaded with FUEL.
At the very least that explains alot of engineering blunders.LOL.

Oh, they did take it into account. The government and its shills are just lying about it. Why would any sane person believe that KEROSENE could cause steel-framed skyscrapers to fall? Many skyscrapers have had fires as intense, and even more intense, and for a longer period of time, yet the only ones that ever fell were the ones on 9/11. None before or since.
Figure 3 shows the comparative energy of impact for the Mitchell bomber that hit the Empire State Building during World War II, a 707, and a 767. The energy contained in the fuel is shown in Figure 4. Considerations of larger aircraft are shown in Figures 5 and 6. The physical sizes of these aircraft are compared with the size of the floor plate of one of the towers in Figure 7. These charts demonstrate conclusively that we should not and cannot design buildings and structures to resist the impact of these aircraft. Instead, we must concentrate our efforts on keeping aircraft away from our tall buildings, sports stadiums, symbolic buildings, atomic plants, and other potential targets.

No one said anything about "resisting" the impact.
The buildings were designed to withstand the impact of a 707 - which you can try to obfuscate but cannot refute.
The difference is size between a 707 and a 767 is relatively small and the 707 had a larger fuel capacity due to a less efficient, earlier, design.
The aircraft were not fully loaded with fuel, admitted in the FEMA report, as it is standard practice to load only enough fuel to make the scheduled flight plus 10% for a margin of safety. Thus the aircraft had about 10,000 gallons of fuel - less than their capacity.
JP 8 (Kerosene) does not burn hot enough even under ideal conditions in a forced air furnace (for example a Jet Engine) to melt steel. Witness the fact that airliners don't crash because the fuel melted the engines.
Paper and Wood are elements of a Class Alpha Fire and do not, even under ideal laboratory conditions, get hot enough to melt steel and there was insufficient quantities to even soften the steel as the steel girder framework acts like a heat sink dispersing the head throughout the structure and thus keeping the temperature down below the critical points.
A localized fire cannot cause a uniform symmetrical simultaneous collapse. The normal failure pattern in a catastrophic structural failure is for there to be a point of greatest weakness. The failure occurs at the weak point first which results in an ASYMMETRICAL failure with the structure moving toward the point of failure. It does not occur simultaneously in 360 degrees causing a uniform symmetrical failure. The uniform symmetrical failure is itself evidence of controlled demolition.
Further in true shill fashion once it was pointed out that the box column center of the building is the primary load bearing structure of the building design you simply followed the fruit loop pattern of avoiding it, denying it, and the trying to shift the debate away from that which you cannot dispute.
You are a liar, are shown to be a liar, and intentionally so. You are either a Shill or an Idiot and at this point Shill is most likely given your repeated use of disinformation tactics.
too bad for you that the WTC fires were not localized...but...suspending disblief for the momenbt and stipulating that they were...they were localized to an area already catostrophically damaged and vital to the structure's support...
According to the Journal of Australian Fire Investigators, kerosene ignites at around 444°F. The temperature that the fire will eventually reach depends on both the combustion rate (based on O2) and the rate at which heat can be disbursed in the given scenario. Again, any firefighter can explain from experience and training that the black, sooty smoke (like that found on 9/11 at the WTC towers) were O2 deprived. Again, please contact professionals to verify this if you wish. In an oxygen deprived environment, higher temperatures cannot be reached. You can test this yourself by comparing a match in the open vs. a match in a bottle with a very small hole.

THE JET fuel fires in the World Trade Center towers did not bring down those two buildings. Indeed, the fuel burned up in minutes. Why, then, did the towers and their 44-story neighbor, WTC-7, which was not struck by a plane, collapse? It's a question that bears generally on fire safety, the safety of building occupants and firefighters and the vulnerability of our buildings to terror by fire.
I expected the National Response Team of the Bureau of Alcohol, Tobacco and Firearms would participate in an investigation that I surely thought would follow the Sept. 11 attacks. The ATF has the authority to investigate arson involving interstate commerce. Certainly, these horrendous attacks should be construed as arson. I later learned that the ATF was told it would not be needed.
I expected the National Transportation Safety Board (NTSB) to head the investigations. It's noted for its thoroughness, objectivity and know-how with respect to large-scale disasters. But it was relegated to flight issues dealing with the two hijacked aircraft and the aircraft debris. The buildings were not to be within the scope of their investigation.
There is an ad hoc investigative group, which is sponsored by the Federal Emergency Management Agency and the American Society of Civil Engineers. But it does not have the full resources that might be made available, nor does it control the site.
I became increasingly concerned the more I learned about the investigative process, or lack of one. The site teams at the towers were focused on rescue, retrieval and cleanup, not investigation. The structural steel pieces, coded with chalk and stamped numbers to indicate their building location, were being sold as scrap metal.
The evidence needed to identify the cause of the collapse and intensity of the fire was being lost. Had the NTSB or ATF been involved, the site would have been secured, evidence documented and protected. Remember how the pieces of TWA Flight 800 were brought up from the ocean bottom off Long Island and restored to preserve structural evidence essential to identifying the cause of the 1996 crash?
WTC family survivors headed by Sally Regenhard last month urged New York City and federal authorities to launch a formal investigation into the collapse of the towers. As Ms. Regenhard said, her son did not die in a fire because of a collapsed building.
High-rise buildings are required to survive the impact of a modern commercial aircraft. Why shouldn't that include survival from the fire that would erupt? Building codes require that the structural elements of high-rise building withstand a three-hour test in a furnace. Why did the buildings collapse in less time? Was this terrorist attack an isolated event that had no bearing on high-rise vulnerability or on the consequences of fire in general?
The scrapping of steel debris should stop immediately, and all of it that has been sold should be impounded. The site should be controlled to conform to standard investigation practices. All records, video recordings and information about those killed and injured should be secured for analysis.
We can learn a great deal from this catastrophe. Many died because they did not expect buildings to collapse. Firefighters should not be the guinea pigs for determining the structural dynamics of buildings caught in flames. The potential for a building's collapse should be known before it happens. Fire safety needs to be incorporated into the normal design process of buildings.
The federal government has a role in developing the needed technology for fire safety. If there ever was a role for government that transcends political ideologies, this is one.
At least let's start with a formal investigation of the WTC collapse.

1. If the World Trade Center (WTC) towers were designed to withstand multiple impacts by Boeing 707 aircraft, why did the impact of individual 767s cause so much damage?
2. Why did NIST not consider a controlled demolition hypothesis with matching computer modeling and explanation as it did for the pancake theory hypothesis? A key critique of NISTs work lies in the complete lack of analysis supporting a progressive collapse after the point of collapse initiation and the lack of consideration given to a controlled demolition hypothesis.
3. How could the WTC towers have collapsed without a controlled demolition since no steel-frame, high-rise buildings have ever before or since been brought down due to fires? Temperatures due to fire don't get hot enough for buildings to collapse.
4. Weren't the puffs of smoke that were seen, as the collapse of each WTC tower starts, evidence of controlled demolition explosions?
5. Why were two distinct spikesone for each towerseen in seismic records before the towers collapsed? Isn't this indicative of an explosion occurring in each tower?
6. How could the WTC towers collapse in only 11 seconds (WTC 1) and 9 seconds (WTC 2)speeds that approximate that of a ball dropped from similar height in a vacuum (with no air resistance)?
7a. How could the steel have melted if the fires in the WTC towers werent hot enough to do so? OR 7b. Since the melting point of steel is about 2,700 degrees Fahrenheit, the temperature of jet fuel fires does not exceed 1,800 degrees Fahrenheit and Underwriters Laboratories (UL) certified the steel in the WTC towers to 2,000 degrees Fahrenheit for six hours, how could fires have impacted the steel enough to bring down the WTC towers?
8. We know that the sprinkler systems were activated because survivors reported water in the stairwells. If the sprinklers were working, how could there be a 'raging inferno' in the WTC towers?
9. If thick black smoke is characteristic of an oxygen-starved, lower temperature, less intense fire, why was thick black smoke exiting the WTC towers when the fires inside were supposed to be extremely hot?
10. Why were people seen in the gaps left by the plane impacts if the heat from the fires behind them was so excessive?
11. Why do some photographs show a yellow stream of molten metal pouring down the side of WTC2 that NIST claims was aluminum from the crashed plane although aluminum burns with a white glow?
12. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues? The combination of thermite and sulfur (called thermate) "slices through steel like a hot knife through butter."
13. Why did the NIST investigation not consider reports of molten steel in the wreckage from the WTC towers?
14. Why is the NIST investigation of the collapse of WTC 7 (the 47-story office building that collapsed on Sept. 11, 2001, hours after the towers) taking so long to complete? Is a controlled demolition hypothesis being considered to explain the collapse?
1. If the World Trade Center (WTC) towers were designed to withstand multiple impacts by Boeing 707 aircraft, why did the impact of individual 767s cause so much damage?
All good questions....let's start with the first one, War. What is .gov telling you to say about this one?
World Trade Center Seven collapsed on September 11, 2001, at 5:20 p.m. There were no known casualties due to this collapse. The performance of WTC 7 is of significant interest because it appears the collapse was due primarily to fire, rather than any impact damage from the collapsing towers. [On the contrary, it appears the collapse was due primarily due to a controlled demolition.] Prior to September 11, 2001, there was little, if any, record of fire-induced collapse of large fire-protected steel buildings. [Before September 11, no steel framed skyscraper had ever collapsed due to fire.]
[On September 11, WTC 7 collapsed totally. It is suggested by the official report that this collapse was exclusively due to fire. No significant evidence is offered to back up this suggestion (after all it is only a suggestion). It should be emphasized that WTC 7 was neither hit by an aircraft nor by significant quantities of debris from the collapse of the twin towers. It is also widely claimed that WTC 1 and WTC 2 collapsed mainly due to fire. I emphasize, that before September 11, no steel framed skyscraper had ever collapsed due to fire. However, on September 11, it is claimed that three steel framed skyscrapers collapsed mainly, or totally, due to fire.]
[As you can see from the above animated-gif, the collapse of WTC 7 certainly has the appearance of a controlled demolition. But, judge for yourself, download and watch the following short video clips and a larger version of the animated-gif:
A Video of the collapse of WTC 7.
Another video of the collapse of WTC 7.
And another video of the collapse of WTC 7.
And yet another video of the collapse of WTC 7.

So we have been presented with the following absurd story:
1. Power to the Twin Towers was wired from the substation in WTC 7 through two separate systems. The first provided power throughout each building; the second provided power only to the emergency systems. In the event of fire, power would only be provided to the emergency systems. This was to prevent arcing electric lines igniting new fires and to reduce the risk of firefighters being electrocuted. There were also six 1,200 kW emergency power generators located in the sixth basement (B-6) level of the towers, which provided a backup power supply. These also had normal and emergency subsystems.
2. Previous to the collapse of the South Tower, the power to the towers was switched to the emergency subsystem to provide power for communications equipment, elevators, emergency lighting in corridors and stairwells, and fire pumps and safety for firefighters. At this time power was still provided by the WTC 7 substation.
3. Con Ed reported that "the feeders supplying power to WTC 7 were de-energized at 9:59 a.m.". This was due to the South Tower collapse which occurred at the same time.
4. Unfortunately, even though the main power system for the towers was switched off and WTC 7 had been evacuated, a design flaw allowed generators (designed to supply backup power for the WTC complex) to start up and resume an unnecessary and unwanted power supply.
5. Unfortunately, debris from the collapse of the north tower (the closest tower) fell across the building known as World Trade Center Six, and then across Vesey Street, and then impacted WTC 7 which is (at closest) 355 feet away from the north tower.
6. Unfortunately, some of this debris penetrated the outer wall of WTC 7, smashed half way through the building, demolishing a concrete masonry wall (in the north half of the building) and then breached a fuel oil pipe that ran across the building just to the north of the masonry wall.
7. Unfortunately, though most of the falling debris was cold, it manages to start numerous fires in WTC 7.
8. Unfortunately, even with the outbreak of numerous fires in the building, no decision was made to turn off the generators now supplying electricity to WTC 7. Fortunately, for the firefighters, someone did make the decision not to fight and contain the fires while they were still small, but to wait until the fires were large and out of control. Otherwise, many firefighters may have been electrocuted while fighting the fires.
9. Unfortunately, the safety mechanism that should have shut down the fuel oil pumps (which were powered by electricity) upon the breaching of the fuel line, failed to work and fuel oil (diesel) was pumped from the Salomon Smith Barney tanks on the ground floor onto the 5th floor where it ignited. The pumps eventually emptied the tanks, pumping some 12,000 gallons in all.
10. Unfortunately, the sprinkler system of WTC 7 malfunctioned and did not extinguish the fires.
11. Unfortunately, the burning diesel heated trusses one and two to the point that they lost their structural integrity.
12. Unfortunately, this then (somehow) caused the whole building to collapse, even though before September 11, no steel framed skyscraper had ever collapsed due to fire.
