how plausible is that . . . three for three . . .

But it wasn't "three for three"- more like 3 for 7 if you count just WTC buildings...or even greater you account for all the other buildings damaged.

I never proposed any scenario . . . I am not a structural engineer or builder or demolition expert . . . I simply find the NIST findings suspect . . . what I thought I saw with my own eyes and what I understand of air defense and disaster preparedness practices, common sense, etc don't add up to me . . . sure one can speculate about plausible explanations all day long . . . so far I am not convinced we have the full truth about what happened before, during and after Sept 11, 2001 . . .Three for three? They were just planning to fly planes into two building, and there was some hope they would collapse. The other buildings were just collateral damage.
What "went perfectly"? Are you suggesting this is EXACTLY what was planned? Or just what happened?
You look at the end result, and yes, it looks quite unlikely that someone could execute a plane to do exactly that. But they didn't. They had a plane to fly planes into the WTC 1&2, the Pentagon, and the White House. They got three of those.
Look at it another way. Consider exactly what would need to go right if this was all planned from the start? DO you really think that this entire sequence of events being the result of a carefully executed plan where nothing went wrong, is more likely than simply what happened after some planes were flowing into buildings?
Really? They planned to fly the planes into the buildings? Had them pre-rigged with explosives that were not affected by the planes. Initiated a controlled demolition on the same floor as where fire had been raging for an hour without disrupting the explosives, and then set fires in building 7, which was also filled with explosives, let that burn for seven hours, then set off the explosives. You think that's more likely than the buildings simply collapsing from the effects of uncontrolled fires?
External Quote:A 32-story building burns for more than 24 hours and does not collapse. It does not collapse because buildings made of steel and concrete, despite what we are led to believe, do not typically fall to the ground because of fire, even a protracted fire as witnessed in Madrid. In fact before September 11th, 2001, no building had ever collapsed as a result of fire alone. In past events, high-rise buildings burned for as long as six days before the fires were extinguished and yet remained standing.
Three high rise buildings significantly damaged and set on fire on 9-11 . . . three buildings completely collapsed . . .But it wasn't "three for three"- more like 3 for 7 if you count just WTC buildings...or even greater you account for all the other buildings damaged.
I just wanted to establish first if you think it's plausible that WTC1 collapsed due to impact and fire.
(And the same question for Oxy)
Three high rise buildings significantly damaged and set on fire on 9-11 . . . three buildings completely collapsed . . .
Were all 10 high rise set on fire and burned for hours ?Sorry- that should read 10 high rise buildings were significantly damaged....3 buildings completely collapsed.
I do not think it plausible that they fell down as they did due to impact and fire damage alone and especially in the case of WTC7 which reportedly fell down half an hour before it actually did.
But what about WTC1. Just looking at that alone - you previously said you did not think the fires burned long enough to bring it down. After seeing the photos above, have you changed your mind?
Mick, I honestly wish I could but I can't. The pictures I downloaded from the link were not appreciably different to the many I have previously seen.
It may help if you picked some out with some detail about how long the fierce fire lasted but there is evidence out there that Edna was in that hole where the plane went in, which should have been the hottest part of the building, i.e. the seat of the fire, for around 40 minutes.
Yes look indeed, that was shortly after the impact but the fuel burned off quickly, as is want to do, then oxygen deprivation kicked in and we had:

That video of Aaron Russo is powerful but simply confirms existing knowledge about the NWO.
I have no problem with Aaron Russo . . . I have an issue with Nick Rockefeller . . . he is possibly a fraud or a very distant relative . . . he isn't mentioned in the family tree at all . . . Aaron may have been played . . .The only thing that video confirmed is that he has similar beliefs to you.
You cannot consider his hearsay claims as a confirmation of facts.
That's a step too far on this thread, George.I have no problem with Aaron Russo . . . I have an issue with Nick Rockefeller . . . he is possibly a fraud or a very distant relative . . . he isn't mentioned in the family tree at all . . . Aaron may have been played . . .

Approach speed isn't cruise speed.I am not sure what you are saying but
So??Approach speed isn't cruise speed.
565 mph at sea level isn't cruise speed.
One airplane was proposed to be near empty of fuel.
The other was actually near full of fuel.
Any more telling points?

The VELOCITIES and the FUEL LOADS are crucially different. Let alone the fact that the 767 is 1.5 times heavier.
The kinetic energy of a moving object depends on the square of its velocity. Twice as quick means four times the energy. The 767 was two and half times as quick as the 707, and, weight for weight, had therefore 6.6 times the energy. But it was 1.5 times heavier, and carried 22,000 pounds more fuel.
Those factors add up. Your argument is gone. The towers received impacts 13 times greater than those theorized in the design process.

Mick. . . do you doubt that such an analysis was done . . . seems totally logical to me that the designer would basically update what happened to the Empire State Building . . . a 707 at some speed makes sense . . .

Correct . . . the issue is not could they withstand the collisions . . . that is moot . . . should they collapse later because of the collisions and the resulting fire is the real issue . . .I don't doubt it. Skilling has discussed it, there's the "white paper" telegram from Roth. I imagine they did at least some calculations to demonstrate the impact would not "push over" the building, or damage enough structural elements to cause a collapse. Remember though this was in 1964, so complex finite element modeling was not possible, computers were very simple back then. The most powerful computer in the world in 1964 was the IBM NORC, with about a millionth the power of an iPhone.
But anyway, it's kind of irrelevant. Doing the analysis NOW on state-of-the-art equipment would also show you that a 600 mph impact would not cause the towers to collapse - and indeed that's exactly what happened.
So Robertson calculated using the maximum take off weight, did he? How interesting. Why would he do that?The maximum takeoff weight for a Boeing 707-320B is 336,000 pounds.
They obviously didn't, George.George B said:should they collapse because of the collisions is the real issue
Correct . . . the issue is not could they withstand the collisions . . . that is moot . . . should they collapse later because of the collisions and the resulting fire is the real issue . . .
I don't have a specific theory on how it happened to the three buildings in question . . . seems to me if according to NIST the fire brought down 1 & 2 because of stripped insulation from the support columns by the aircrafts impacting the buildings and 7 came down not because of stripped insulation but by the failure of an overheated expansion joint on one critical column . . . yet this never happened before or since in a complete building collapse . . . I am not sure I buy it . . . don't know what happened but think there is much room for doubt . . .What do you think? Is it plausible? You've seen in the photos how extensive the fires were. You know that steel suffers both from thermal expansion and weakening. It seems reasonable that some columns were damaged or destroyed, and some had their insulation stripped. There was also no audio of demolition style explosions during or before collapse. There's also the incredible difficulty of flying the plane into the building at a particular floor, and then initiating collapse at that floor.
I mean, it all seems perfectly reasonable to me. I can understand people who WANT to believe in a conspiracy, but it seems to me that to a neutral observer, the official story makes perfect sense. The alternate stories (controlled demolition) make no sense.
(emphasis mine)
It fell because of the fires (although obviously having some broken columns did not help). Nobody is suggesting otherwise.
Seems they initiated according to NIST a chain of events that resulted in a catastrophic collapse of three of the tallest buildings in the US . . . Why? . . . poor construction concepts in light of 20/20 hindsight . . . inadequate insulation . . . fate . . . or other?Ok, so can we now leave the planes out of it and accept that they had little to no effect, apart from being the source of the fires, in the collapse of any of the 3 buildings? Is that agreed?

That for me is a big leap . . . if one could ignite thousands of pounds of jet fuel in the towers any other way with exterior air sources . . . I guess . . . I will admit NIST does imply what you are saying . . .Yes but apart from the 'initiation factor' can we all agree that they were not responsible for the collapses?

The WTC towers likely would not have collapsed under the combined effects of aircraft impact damage and the extensive, multi-floor fires that were encountered on September11, 2001, if the thermal insulation had not been widely dislodged or had been only minimally dislodged by aircraft impact.In the absence of structural and insulation damage, a conventional fire substantially similar to or less intense than the fires encountered on September 11, 2001, likely would not have led to the collapse of a WTC tower.

These buildings are not a "tube in a tube" design. The towers were steel without concrete. The towers perimeter steel walls were held in place by the trusses and those trusses were connected to the perimeter columns by small bolts. They also weren't hit by an airliner at 500 miles an hour. While it's true they were designed to withstand the impact of a smaller 707, they never factored in the removal of fire proofing or fuel in the wings.
[url]http://www.pbs.org/wgbh/nova/wtc/minu-trans.html[/URL]"It is impressive that the World Trade Center towers held up as long as they did after being attacked at full speed by Boeing 767 jets, because they were only designed to withstand a crash from the largest plane at the time: the smaller, slower Boeing 707. And according to Robertson, the 707's fuel load was not even considered at the time. Engineers hope that answering the question of exactly why these towers collapsed will help engineers make even safer skyscrapers in the future. ASCE will file its final report soon, and NIST has been asked to conduct a much broader investigation into the buildings' collapse."
Contrary to popular belief September 11, 2001 was not the first time a steel framed building collapsed due to fire. Though the examples below are not high rise buildings, they make the point that fire alone can collapse a steel structure.
The McCormick Center in Chicago and the Sight and Sound Theater in Pennsylvania are examples of steel structures collapsing. The theater was fire protected using drywall and spray on material. A high rise in Philly didn't collapse after a long fire but firefighters evacuated the building when a pancake structural collapse was considered likely. Other steel-framed buildings partially collapsed due fires one after only 20 minutes.
The steel framed McCormick Center was at the time the World's largest exhibition center. It like the WTC used long steel trusses to create a large open space without columns. Those trusses were unprotected but of course much of the WTC lost it's fire protection due to the impacts.
"As an example of the damaging effect of fire on steel, in 1967, the original heavy steel-constructed McCormick Place exhibition hall in Chicago collapsed only 30 minutes after the start of a small electrical fire."

[Note this article has several comments from engineers who back the
WTC collapse theory.]
"The unprotected steel roof trusses failed early on in the fire"
http://www.chipublib.org/004chicago/disasters/mccormick_fire.html
The McCormick Place fire "is significant because it illustrates the fact that steel-frame buildings can collapse as a result of exposure to fire. This is true for all types of construction materials, not only steel." wrote Robert Berhinig, associate manager of UL's Fire Protection Division and a registered professional engineer. He also discusses UL's steel fire certification much more knowledgably than Kevin Ryan. He is an example of one more highly qualified engineer who supports the collapse theory.
I have a few sources that prove that the towers fell due to a mix between fires an a 767 plane, here goes:
Yes but apart from the 'initiation factor' can we all agree that they were not responsible for the collapses?
Sorry Clock but that does not prove anything. There is no 'proof' one way or the other, simply competing theories and it basically boils down to, do you beleive the 'official theory' or not.

Why is it I am unsurprised when a thread that reflects badly on authority and does not fit with the officially promoted perception, gets side tracked to the 'off topic and ramblings' section. And even worse it gets drastically edited to remove adverse information and legitimate comments. It just appears the 'CT shooter did not use an assault rifle', thread was too embarrassing.
