MikeyDB said:The facts speak for themselves Toro, there is a growing mountain of evidence that the laws of physics themselves would have to have been suspended on that day for the twin towers to have collapsed that quickly without some internal explosions to assist the cascade downward.
The story...
The towers fell at or near free fall speeds, a possible sign of controlled demolition.
Our take...
Stage one in establishing this claim is to calculate the actual time it took for the towers to fall, but dust clouds obscuring the end of the collapse make this difficult.
Coming up with a final figure involves a degree of estimation, which is probably why the times you’ll find online range from 8.4 to 15 seconds..
The rate of free fall in a vacuum, at least, is easier to define. The towers were around 417 metres tall (excluding the spire), giving 417 = 0.5 gt^2, so with g = 9.8m/s^2 that gives a time of about 9.22 seconds. So if you dropped a ball off the roof, and there were no air resistance, then that’s the time it would take to reach the ground.
Now we have a basis for comparison. If the towers really did fall completely in 8.4 seconds, then that would actually be faster than gravity, requiring some major additional force to push from above (or pull from below). We’ve seen it suggested that explosives created a “powerful vacuum”, for instance, but that’s not apparent from the collapse videos and images. Like this one, for instance.
Collapse
Large chunks of rubble, which are in free fall, are clearly falling faster than the rest of the building. The base of the massive chunk lower left is, what, 20 storeys lower than the top of the right-hand corner of the building? (And there may be rubble below that, and the building may be intact higher higher still). This suggests we should be looking at a collapse time greater than our 9.22 second freefall figure, not less.
How much greater? If the video evidence gives such a great ranges of guesses, then maybe another approach is required, at least as a crosscheck. We tried looking at the audio of each collapse, and came up with a minimum of 14 seconds in each case (see our South Tower and North Tower pages for more), and the potential for them to have taken several seconds longer. Calculating these times involves far too many judgement calls for us to claim proof of anything, but we do think it adds significantly more support to the 15+ seconds collapse time, and makes the 8.4 second end of the spectrum look particularly unlikely.
We can cross-check this by looking at the seismic evidence. Although often presented as supporting the shortest 8-point-something time, in our view there’s a case for arguing that this, too, indicates the collapse time was much, much longer.
And if you look carefully, then you will find some videos that also back us up. Here’s one indicating to us that the first collapse took more than 12.5 seconds.
Where people have quantified the collapse time they thought should have arisen, it’s not always helpful to the conspiracy case. D.P. Grimmer, for instance, believes the towers demonstrably fell in around 10 seconds, and has this to say about the time it should have taken in one scenario (if 30% of the gravitational energy of the collapse was lost in pulverising the concrete):
Now the observed time t = 10 seconds (a free fall time, the fastest possible time under g = 9.8 m/sec/sec = 32 ft/sec/sec = 32 ft/s exp2). For the cloud debris creation to absorb 30% of the gravitational energy, the observed time of fall would be 10s x 1.195, or almost 12 seconds. This long a collapse time was observed by no one. Clearly, there are serious flaws in the official explanation/conspiracy theory.
http://www.physics911.net/thermite.htm
So Grimmer thinks a 12 second time might be more reasonable, in the case he describes? Yet we (and others) suggest a collapse time of 15 seconds or more is more accurate, significantly longer still.
Of course the main issue is still whether each tower fell faster than it should have done in air, not a vacuum. Read more on this in an extremely detailed and interesting paper from Dr Frank Greening, which he’s kindly agreed to let us host here.
And in the interests of balance, check out the “Refutation of the Official Collapse Theory”. Be sure to pay attention to their calculations of collapse time, and the way the pancaking towers are assumed to come to a dead stop as each floor is hit.
MikeyDB said:And the next time you want to weld some construction grade steel please feel free to light yourself a pail of kerosene and see how long it takes for the steel to melt...
"Melted" Steel
CLAIM: "We have been lied to," announces the Web site AttackOnAmerica.net. "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." The posting is entitled "Proof Of Controlled Demolition At The WTC."
FACT: Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength--and that required exposure to much less heat. "I have never seen melted steel in a building fire," says retired New York deputy fire chief Vincent Dunn, author of The Collapse Of Burning Buildings: A Guide To Fireground Safety. "But I've seen a lot of twisted, warped, bent and sagging steel. What happens is that the steel tries to expand at both ends, but when it can no longer expand, it sags and the surrounding concrete cracks."
"Steel loses about 50 percent of its strength at 1100°F," notes senior engineer Farid Alfawak-hiri of the American Institute of Steel Construction. "And at 1800° it is probably at less than 10 percent." NIST also believes that a great deal of the spray-on fireproofing insulation was likely knocked off the steel beams that were in the path of the crashing jets, leaving the metal more vulnerable to the heat.
But jet fuel wasn't the only thing burning, notes Forman Williams, a professor of engineering at the University of California, San Diego, and one of seven structural engineers and fire experts that PM consulted. He says that while the jet fuel was the catalyst for the WTC fires, the resulting inferno was intensified by the combustible material inside the buildings, including rugs, curtains, furniture and paper. NIST reports that pockets of fire hit 1832°F.
"The jet fuel was the ignition source," Williams tells PM. "It burned for maybe 10 minutes, and [the towers] were still standing in 10 minutes. It was the rest of the stuff burning afterward that was responsible for the heat transfer that eventually brought them down."

huxley said:BUILDING 7 collapsed no plane hit it.(these are all facts)
The story...
As WTC7 sustained no significant damage from the collapses of towers one and two, it shouldn't have been on fire, and there's definitely no reason for it to collapse.
Our take...
Some 9/11 photos show collapse debris that appears to be heading for WTC7 (the light-brown building in the shot below)..
WTC7Hit1
The angle of shot makes it difficult to say where that might hit (see this page for another view), but reports from the scene do suggest significant damage.
Battalion Chief John Norman
Special Operations Command - 22 years
From there, we looked out at 7 World Trade Center again. You could see smoke, but no visible fire, and some damage to the south face. You couldn’t really see from where we were on the west face of the building, but at the edge of the south face you could see that it was very heavily damaged.
http://www.firehouse.com/terrorist/911/magazine/gz/norman.html
Chris Boyle expands on what he saw when he viewed the south side, not just the corner.
Captain Chris Boyle
Engine 94 - 18 years
Boyle: ...on the north and east side of 7 it didn’t look like there was any damage at all, but then you looked on the south side of 7 there had to be a hole 20 stories tall in the building, with fire on several floors. Debris was falling down on the building and it didn’t look good.
Firehouse: When you looked at the south side, how close were you to the base of that side?
Boyle: I was standing right next to the building, probably right next to it.
Firehouse: When you had fire on the 20 floors, was it in one window or many?
Boyle: There was a huge gaping hole and it was scattered throughout there. It was a huge hole. I would say it was probably about a third of it, right in the middle of it. And so after Visconti came down and said nobody goes in 7, we said all right, we’ll head back to the command post. We lost touch with him. I never saw him again that day.
http://www.firehouse.com/terrorist/911/magazine/gz/boyle.html
Another report talks of damage that suggested collapse was a real possibility:
...Captain Varriale told Chief Coloe and myself that 7 World Trade Center was badly damaged on the south side and definitely in danger of collapse. Chief Coloe said we were going to evacuate the collapse zone around 7 World Trade Center, which we did.
http://graphics8.nytimes.com/packages/pdf/nyregion/20050812_WTC_GRAPHIC/9110462.PDF
Fire chief Daniel Nigro says further assessment of the damage indicated that it was severe:
The biggest decision we had to make was to clear the area and create a collapse zone around the severely damaged [WTC Building 7]. A number of fire officers and companies assessed the damage to the building. The appraisals indicated that the building's integrity was in serious doubt.
http://www.cooperativeresearch.org/entity.jsp?id=1521846767-634
Another fireman reported damage that progressed as the day wore on.
Deputy Chief Peter Hayden
Division 1 - 33 years
...also we were pretty sure that 7 World Trade Center would collapse. Early on, we saw a bulge in the southwest corner between floors 10 and 13, and we had put a transit on that and we were pretty sure she was going to collapse. You actually could see there was a visible bulge, it ran up about three floors. It came down about 5 o’clock in the afternoon, but by about 2 o’clock in the afternoon we realized this thing was going to collapse.
Firehouse: Was there heavy fire in there right away?
Hayden: No, not right away, and that’s probably why it stood for so long because it took a while for that fire to develop. It was a heavy body of fire in there and then we didn’t make any attempt to fight it. That was just one of those wars we were just going to lose. We were concerned about the collapse of a 47-story building there. We were worried about additional collapse there of what was remaining standing of the towers and the Marriott, so we started pulling the people back after a couple of hours of surface removal and searches along the surface of the debris. We started to pull guys back because we were concerned for their safety.
http://www.firehouse.com/terrorist/911/magazine/gz/hayden.html
So why wasn’t this damage photographed, ask people like David Ray Griffin (http://911review.com/articles/griffin/nyc1.html)? If they were to show you the smoke pouring from every floor of the building, then that may make it obvious... But it could also make you question the “small and limited” fires idea, which is why shots like this aren’t shown so very often.

Conspiracy theorist say World Trade Center 7 is the best proof for controlled demolition because it wasn't hit by Airliners and only had a few fires. It also had a confession from the building owner who said he "Pulled" it. But this is deceptive because while building 7 wasn't hit by an airliner it was hit by the large perimeter columns of the Tower collapse. It was 400 ft away but the towers were more than 1300 ft tall. As the tower peeled open it easily tilted over to reach building 7.
MikeyDB said:Are you suggesting then that at IMPACT point "I-Point" plus half a second that every piece of carpet paper draperies, every combustible material flashed to flame, heated up within I+3 seconds to a temperature sufficient to melt structural steel then every supporting steel member was heated to its failrure temperature and the building collapsed in roughly eleven seconds is a rational conclusion?
