Cassi, thanks for posting that. It's hard to find real information in the forest of propaganda.
So, what REALLY happened on September 11, a.k.a. the unknowns...???

5. Evidence for Explosives in the Twin Towers
Millions of people around the world watched the WTC events unfold live on CNN on September 11th, 2001, in near-disbelief. They saw huge clouds of smoke billowing over Manhattan and saw the towers collapse ... in a curious way. They did not fall over; they imploded, in the way that most people have seen when a building is destroyed in a controlled demolition: the building does not collapse in a chaotic way, hurling debris over a wide area; rather it collapses upon itself. This was how the WTC towers collapsed. That the towers were demolished in a controlled manner was noted immediately by some astute observers:

Subject: WTC bombingOk, is it just me, or did anyone else recognize that it wasn't the airplane impacts that blew up the World Trade Center? To me, this is the most frightening part of this morning. ...
If you watch the time sequence, you'll see that it happens like this:
- A plane hits tower #1, blowing a hole in it high up. The expected things then happen:
- The building stays up. A reinforced concrete building is *extremely* strong. Terrorists set off a large bomb *inside* that building without significant damage. ...
- The second plane hits the second tower, lower and moving faster. It blows a bigger hole through it, showering debris on the street, but the building is clearly still standing and still looks quite solid. - The second building begins burning, also from the impact point up.
- Perhaps a half hour later, the fire in the first building *goes out*. It is still smouldering and letting off black smoke, but there is no flame. ...
- The fire in the second building goes out.
- Then, later, the second building suddenly crumbles into dust, in a smooth wave running from the top of the building (above the burned part) down through all the stories at an equal speed. The debris falls primarily inward. The tower does not break off intact and collapse into other buildings. ... The crumbling comes from the top (above the damage). It moves at a uniform rate. All of the structural members are destroyed in a smooth pattern, so there is no remaining skeleton. The damage is uniform, symmetric, and total.
In summary, it looks exactly like a demolition — because that's what it is.
- The first tower collapses in a similar demolition wave.
There's no doubt that the planes hit the building and did a lot of damage. But look at the footage — those buildings were *demolished*. To demolish a building, you don't need all that much explosive but it needs to be placed in the correct places (in direct contact with the structural members) and ignited in a smooth, timed sequence. ...

(Full text of this message is here .)Initially the explosives theory suffered from the problem that the mainstream media did not report that anyone heard explosions just prior to the WTC collapse. But in the last year reports have surfaced, and there is now even video evidence available to anyone which shows that explosions actually did occur within the Twin Towers prior to their collapse.
Television viewers watching the horrific events of Sept. 11 saw evidence of explosions before the towers collapsed. Televised images show what appears to be a huge explosion occurring near ground level, in the vicinity of the 47-story Salomon Brothers Building, known as WTC 7, prior to the collapse of the first tower.
A Danish website offers a 4-hour video containing visual evidence of what happened on September 11th which has been suppressed or ignored by the mainstream media:... One eyewitness whose office is near the World Trade Center told AFP that he was standing among a crowd of people on Church Street, about two-and-a-half blocks from the South tower, when he saw "a number of brief light sources being emitted from inside the building between floors 10 and 15." He saw about six of these brief flashes, accompanied by "a crackling sound" before the tower collapsed. Each tower had six central support columns.
One of the first firefighters in the stricken second tower, Louie Cacchioli, 51, told People Weekly on Sept. 24: "I was taking firefighters up in the elevator to the 24th floor to get in position to evacuate workers. On the last trip up a bomb went off. We think there were bombs set in the building."
Kim White, 32, an employee on the 80th floor, also reported hearing an explosion. "All of a sudden the building shook, then it started to sway. We didn't know what was going on," she told People. "We got all our people on the floor into the stairwell ... at that time we all thought it was a fire ... We got down as far as the 74th floor ... then there was another explosion."
— Eyewitness Reports Persist Of Bombs At WTC CollapseVideo Clips of the falling Towers were often edited in a manner that prevented the TV viewers in getting the "Full picture" of the entire tower collapse. ... During my 1000 hours of video investigation I have found only very few of such "Full picture long distance shots" which showed the entire tower (from top to bottom). Most of the video-clips we saw on Sept. 11 (and in the weeks that followed) would be edited versions ... [which] did not give any evidence of the numerous "clouds" from EXPLODING Bombs "popping out of the windows" of the WTC facade far below the crash level of the collapsing tower. ... Someone in the "editing rooms" did not want to give us the "Full Picture"!
But some crucial BOMB video evidence did in fact get out! In my video I will show you 5 significant "DUST CLOUDS" from Demolition Bombs exploding INSIDE the WTC Towers. These "Bomb Clouds" were located circa 20 and 40 levels BELOW the "Crash level" of the falling Towers. ... [T]hey give full evidence of a Distinct Demolition Bomb being exploded FAR BELOW the "Crash-Point-level".
— Bombs Inside the World Trade CenterAnd it was not only the Twin Towers which were demolished deliberately but also the building known as WTC Seven.
Not detailed in the monopoly press, some fire-fighters who survived Black Tuesday, contend there were explosions in the buildings, in a portion of the twin World Trade Center towers, separate and apart from the impact of the planes hitting the buildings. ... Were within-the-buildings explosives remotely triggered off to collapse the towers like done with old buildings? And there are good reasons to believe that within-the-building explosives caused the mysterious collapse, late on the evening of Black Tuesday, of World Trade Center Building 7. — Sherman H. Skolnick: The Overthrow of the American Republic, Part 14
The Twin Towers collapsed in a very strange manner, leaving almost nothing but metal fragments from the outer shell and huge quantities of fine ash and dust, without the central steel columns from the lower sixty floors either standing or fallen. This is very strange. Look at all that dust (click on the image for an enlargement and for two further pictures of the clouds of dust). It is as if some high-energy disintegration beam had been focused on the tower, pulverizing every concrete slab into minute particles of ash and dust. But although some kind of "black" technology may have been used in the demolition of the Twin Towers, we do not need to establish this, since their collapse can be explained as a controlled demolition brought about by explosives. In fact (as Christopher Bollyn was the first to point out in his Open Letter) evidence for massive explosions was captured by a seismograph located 34 km from the WTC:
A "sharp spike of short duration" is how an underground nuclear explosion appears on a seismograph. The seismograph which recorded this data was operated by Columbia University’s Lamont-Doherty Earth Observatory. A report was published by the American Geophysical Union in the November 20 issue of Eos, but the authors misinterpreted the data. They assumed, and thus reported, that the two largest signals were caused by the collapses of the Twin Towers. But:
During the collapse, most of the energy of the falling debris was absorbed by the towers and the neighboring structures, converting them into rubble and dust or causing other damage — but not causing significant ground shaking. — Dr. Arthur Lerner-Lam, Director of Columbia University's Center for Hazards and Risk Research, as quoted in Earth Institute News
Christopher Bollyn:
Seismic Evidence Points
to Underground Explosions
Causing WTC CollapseSo if most of the energy of the falling debris was dissipated and was not the cause of the major spikes in the seismic record then what was? Perhaps massive explosions in the lowest (level -7) basements of the Twin Towers, besides the supporting steel columns where they met the Manhattan bedrock? Perhaps even small nuclear explosions?
This, together with numerous small explosives detonated at every ten or so levels of the supporting steel columns, would explain one observation which the official story does not explain: Why were the lower parts of the massive supporting steel columns not left standing after the collapse? If the official story is true, that the damage was caused by the impacts and fires, which occurred only in the upper floors, and that the floors then pancaked, one would expect the massive steel columns in the central core, for, say, the lowest 20 or 30 floors, to have remained standing, which they did not. But this is understandable if the bases of the steel columns were destroyed by explosions at the level of the bedrock. With those bases obliterated, and the supporting steel columns shattered by explosions at various levels in the Twin Towers, the upper floors lost all support and collapsed to ground level in about ten seconds.
Further evidence for explosives is provided by video evidence of the way in which the South Tower collapsed: The top thirty or so floors keeled over at the beginning of the collapse. If the floors had pancaked in the way that the official story has it then these top floors should have fallen straight down. But if explosives somewhere in the region of the impact level had blasted the steel supporting columns in the core then it is understandable that the top floors tilted over (probably in the direction of the damaged corner where the plane hit). The explosive devices could have been encased in heat-resistant material so that any of them which were exposed to fire would not detonate. If timing was critical then they could be detonated by remote control (a radio or microwave signal) at the right time. Even if the fires disabled the bombs on the levels where the planes hit, they would not disable the bombs on the floors below the fires. No wires, CPUs or timing devices are needed, just some way for each explosive device to respond to the unique signal causing it to explode. Even a timing sequence may not have been needed — simultaneous detonation of each device in the above-ground levels may have been sufficient to produce the intended result.
The time t required for an object to fall from a height h (in a vacuum) is given by the formula t = sqrt(2h/g), where g is the acceleration due to gravity. Thus an object falling from the top of one of the towers (taking h = 1306 feet and g = 32.174 ft/sec 2 ) would take 9.01 seconds to hit the ground if we ignore the resistance of the air and a few seconds longer if we take air resistance into account. The Twin Towers collapsed in 10 - 15 seconds, close to free fall. Following the start of the collapse the upper floors would have had to shatter the steel joints in all 85 or so floors at the lower levels. If this required only a second per floor then the collapse would have required more than a minute. But the material from the upper floors ploughed through the lower floors at a speed of at least six floors per second. This is possible only if all structural support in the lower 85 or so floors had been completely eliminated prior to the initiation of the collapse. Since the lower floors were undamaged by the plane impacts and the fires, the removal of all structural support in these floors must have been due to some other cause — and the most obvious possibility is explosives. Thus the speed of the collapse (not much more than the time of free fall) is strong evidence that the Twin Towers were brought down in a controlled demolition involving the use of explosives (or some other destructive technology) at all levels.
For a week after the collapse of the Twin Towers there were areas beneath the surface which remained intensely hot.
AVIRIS data collected on September 16, 2001, revealed a number of thermal hot spots in the region where the WTC buildings collapsed. Analysis of the data indicated temperatures greater than 800 o F in these hot spots (some over 1300 o F). — U. S. Geological Survey Report
What was the source of this heat? Could it have been residual heat from underground nuclear explosions?
The Twin Towers were not the only buildings in the WTC complex about which questions can be asked. There were other WTC building "collapses".
A way to prove that the supporting steel columns of the Twin Towers had been blasted by explosives would be to examine fragments from them among the debris for evidence of what metallurgists call "twinning". But the WTC debris was removed as fast as possible and no forensic examination of the debris was permitted by the FBI or any other government agency. Almost all the 300,000 tons of steel from the Twin Towers was sold to New York scrap dealers and exported to places like China and Korea as quickly as it could be loaded onto the ships, thereby removing the evidence. See Debris Mountain Starts to Shrink, an article which shows that Controlled Demolition Inc. (a world leader in the demolition of tall buildings) was apparently keen to have the debris removed and disposed of as soon as possible and was able to come up with a detailed plan for doing so within eleven days of the collapse of the Twin Towers, suggesting that this company had detailed knowledge of the Twin Towers and the entire WTC complex prior to September 11th.

reporter,
this is from the article you posted:
<<<Using jet fuel to melt steel is an amazing discovery, really. It is also amazing that until now, no one had been able to get it to work, and that proves the terrorists were not stupid people. Ironworkers fool with acetylene torches, bottled oxygen, electric arcs from generators, electric furnaces, and other elaborate tricks, but what did these brilliant terrorists use? Jet fuel, costing maybe 80 cents a gallon on the open market.>>>
i am not an expert on pure steel constructions such as skyscrapers but i do know a bit about the use of steel in steel concrete buildings (i went to a high school for architecture). the steel in the construction is under high tention and stress. the maximum tensile strength goes down if the temperature is raised. so if you heat up a concrete ceiling it will collaps if the steel that carries most of the tension reaches a critical treshold temperature. i would assume that it was the same with the WTC. heating up the steel reduced the permitted load on the structure. it was not necessary to actually melt the metal. simply reducing the strength of the material was enough.
aside from that...how likely are the alternative explanations? -
reporter
I would like to add (and that is included in the earlier articles posted) that the calculations make no allowance for
1: The heat in steel migrates from the heated area to cooler areas
2: The south tower was hit at a very bad angle so that most of the fuel burned OUTSIDE upon impact, yet this tower collapsed first! even after the other tower suffered a direct hit and had a 20-minute head start!
3: The calcuations assume only ONE floor with maximum fire intensity...evidence of course shows heat dissipation over multiple floors in both crashes.
4: Black smoke indicates cooler temperatures and/or incomplete combustion.
5: Load factors leave a 5 to 6:1 ratio for margins of safety. For example, if a bridge is rated 50 tons, it is constructed to maximum strength of at least 250 tons. Working strength and breaking strength are two different entities.

Here is some further detail on just how weird it was that the south tower fell first, if you examine what happened to a large part of the fuel on that failed crash. Actually, the writer here explains how both ops were a failure in terms of maximum damage objectives.

reporter,
think about it....how could that have possibly been done??? first they put large amounts of explosives in the towers. than the steer the planes exactly into the floors that contain the explosives!? that is an impossibility.
also the tower that was hit on the lower level fell probably first because of the higher weight on the steel structure. therefore less time was required to heat up the steel enough for the structure to collaps.
also, why would someone fly planes into the building if he has already palaced huge amounts of explosives in the building?
the whole theory seems very far fetched.
