I got this from another forum, thought it was an interesting bunch of points I wanted to share with you: Also here is a link to something a lot of
folks don't know about.
Construction on the towers, north and south began september 11 1971. At 1350 feet they were two of the tallest most famous buildings on earth. A fact
most people don't know is they were engineered like proverbial brick outhouses. They were overengineered to withstand major winds and hits from large
airliners. They were built with 47 enormous steel core columns. Together with 236 large exterior steel columns that were welded and bolted together
with steel plates. Further, there were steel trusses which cris-crossed making a mesh that connected every other exterior column. Plus there was
diagonal bracing and steel rods connecting the trusses. There were also corrogated pans with poured concrete on every floor and all of this was
anchored in a very deep and heavy foundation.
The buildings were architechturally designed to absorb energy and to sway in storms. According to witnesses in the buildings near where the planes
hit, the towers swayed for a few seconds as intended. Other witnesses in the area said that the noise and blast was significant but the tremor felt at
the time of contact was minimal.
Fact. No steel structure building in new york, the united states or in the world has ever come down due to fire. In the last 100 years, dozens of
steel buildings have caught on fire and burned for long periods of time and not come down. A good example is the Meridian Plaza in Philadelphia, a 38
story office building that in 1991 had a hot fire. It burned on 8 floors for 19 hours and theee firefighters died but it did not come close to
bringing down the building. In contrast, the world trade center north tower fire lasted 1 hour and 43 mintues and the world trade center south tower
lasted 56 mintues. They both burned significant portions of rubble, sheat rock, carpet, furniture, etc producing lots of black smoke indicating they
were burning in efficiently and were relatively cool fires.
A: Steel melts at 2700 degress Farenheit. B: Jet fuel when mixed in precise proportions with will burn briefly at 1800 degrees farenheit. C: because
of the debris, carpeting, sheat rock, furniture, concrete, aluminum, etc and lack of oxygen, the fire at the world trade center probably burned at
1200 to 1300 degrees farenheit.
It must also be remebered that a significant portion of the jet fuel exploded outside of the buildings (i.e.south tower). The exterior columns were
exposed to the air on three sides and would dissipate heat at a fast rate. And the beams and columns were coated with fire proofing materials.
The official story is the buildings came down at point of contact because the intensity of the fire caused the trusses to push out the columns. Yet,
if one views the wholecreated in the north tower by the plane, there are onlyrelatively small fires. And the fires must not be excessive because you
can see two people standing and staring out near the opening.
The top section of the south tower began to tilt at approx 9:59 am. At this moment, a large cloud of grey dust suddenly puffed out of the building.
The 35 stories of the top section continued to tip to 23 degrees past vertical. At this point, the upper segment was hanging over the edge by approx
65 feet. In frame by fame pictures, one can see the concentric and uniform mushrooming grey cloud rapidly expand to envelp the building. As this is
happening, one can see debris being blown away from the building with an extremely powerful blast. The overhanging upper section was then mysteriously
shrouded and never seen again. Then the whole building came straight down. With an incredibly fast 10.4 seconds the once might tower was reduced to a
pile of totally pulverized remains. Government story is that this building experienced a compression or a pancake demoltion caused by weakened trusses
and weight from above. At first this explanation sounds plausible, especially because this is what the television reports have told us time and time
again. But common sense would indicate that the center of gravity of the top section was not centered over the lower section. Thus, if there was a
compression demolition, it would not be uniform because the center of gravity was considerably off center. Secondly, the severed top section that was
tilting very much over the edge would fall somewhat independently. Third, this section would fall at a fast rate than the anchored lower section
because it would not meet the resistance of the intact lower section. Fourth, the top and lower sections would break into pieces, they would not
pulverize. None of these four things happened.
The complete demolition of the North Tower took only 8.1 seconds. The north tower came neatly down and it's remains were equally powdered.
Facts are very stubborn things. According to the law of falling bodies as put forth by Galileo, the total distance traveled at the end of any specific
time in a total vacuum is calculated by the following formula: Distance equal 32.16 divided by 2 times time in seconds squared. If there is any
resistance, then the speed and time of the falling body slows down in relation to this resistance. In the case of the two towers, we know they were
1350 feet tall. Thus you'd have the following equation for the fastest time of total drop in a total vacuum. 1350=32.16 divided by 2 times time in
seconds squared. This works out to 9.1627 seconds as the fastest time these buildings could come down. This presents interesting questions because the
south tower came down in 10.4 seconds and the north tower came down in 8.1 seconds. Additionally, there was resistence and plenty of it. The
resistance was the massive lower sections that were stabalized by over 250 major interior and exterior steel columns and thousands of steel trusses.
This defies the laws of gravity. Thus, either the height of the towers is wrong, the time of the falls is wrong, the scientific formula is wrong, or
something pulled down these buildings at a faster rate.
Remember the grey could that concentrically blasted out and down the imploding buildings and chased thousands of new yorkers down the street while
covering the area with a sand like substance? That substance was cement and other material that was crystalized. Could the blast of jet fuel create
this crystalization? No. At full blast jet fuel only expands at 208 ft. per second. Could a compression demolition do this? No because there is not
enough latent energy. The cement would crack and break but not pulverize. The only way the molecular composition of these materials could be so
scrambled is if there were small cacle nuclear devices or there were high tech explosives. Since there is no reading of radioactive activity that can
be confirmed, modern explosives are the logical choice. High tech explosives such as rtx or c4 can expand at over 1000 ft per second and create
extremely hot temperatures. Modern explosives could cause the crystalization of the building materials, while creating a vacuum that could pull down
the buildings at a faster rate than normal speed and leave a residue of extremely high temperatures.
FEMA put forth this hurried and short explanation concerning the collapse of the two towers. "Expansion of floor slabs and faming result in outward
deflaction of columns and potentional overload." From this 'expert' opinion, the adminstration and media have promoted the pancake theory which
says the floor trusses expanded which caused the columns to buckle, the joints to break and the floors then compressed on themselves. But an objective
observer would consider these important points. A: never before has any steel framed building come down because of fire. The fires at the towers
burned for short periods of time and at low heat levels. b: for the wtc buildings to react in this way, literally thousands of super heavy duty joints
and welds would have to have snappe at exactly the same instant (Remember, these buildings were engineered for expansion and flexibility. There was
also the fire retardent sprayed on all of the steel and the burning patterns were inconsistent throughout the floors). c: A pancake collapse could not
come down with such speed. d: a pancake collapse would not have the latent engery to crystalize the building materials, to shred aluminum, or blast
rubble to such distances. e: a pancake collapse would not create or maintain the asronomical heat patters that were recorded and monitored for weeks
On September 16, Nasa flew a plane over the site to take measurements and create a thermosurface map. In this time, hundred of truckloads of debris
had been carried off and firemen had sprayed millions of gallons of water on the smoking rubble. The results show there were several hot spots with
temperatures over 1000 farenheit on the surface with one spot at the south tower recording 1377 degrees (nasa map five days later). Most notice the
area smoked for weeks. Since neither tons of jet fuel nor compression demolition have the potential to create this kind of heat, much less maintaining
this heat for days afterwards, an impartial detective would have to conclude that there was another source for these extreme temperatures. Chistopher
Bollyn of the American free Press has noted that the steel columns at the bast of the foundations, 70 feet underground were melted. That would mean
temperatures would have to exceed 2700 degress. Hello? Is anyone in the media, government, or law enforcement listening?
WTC 6 is a big part of the puzzle. After wtc 2 was hit, there was a huge explosion that appears to eminate frmo the center section of WTC 6. Only
later did it catch on fire. It then burned for hours at a very hot temperature and the fire was eventually put out. An objective investigator would
ask a: what caused the building to explode before it caught on fire? b:After the center of the building had been blown apart and had experienced a
long and intense fire why did it not come down like WTC 1, 2 and 7?
The facts around WTC 7, a 47 story building, are even more bizarre. 7 was built on top of a major electrical substation that housed 10 large
transformers. Futher, the landlord let the tenants install diesel fuel tanks with a capacity of over 42000 gallons to take care of emergency power
generation in the building. Some of the major tenants were: Mayor Guliani, who made a 13 million dollar control bunker in the building. The CIA,
Department of Defense and the Secret Service. It seems odd the mayor would make such an expensive bunker in a building on top of such potentially
explosive tanks and transformers. Additionally, 7 was not reported to be on fire until 3 pm. This is 5 hours after 1 and 2 collapsed. These fires were
minor and burned for less than 3 hours when the whole thing came down at 5:25. It appears from pictures to be a totally conventional demolition. There
were no huge explosions, the building walls fell neatly in on themselves and the rubble was cracked and broken but not pulverized. It is of interest
that FEMA nor anyone else made a report or suggestion as to what happened to this building that housed some very interesting tenants.
It is said that every picture tells a story. In the case of seismic activity as documented by Columbia Univeristy Seismology group, there are some
interesting stories. The south tower registered a tremor of 2.1 and came down in aprox 10.4 seconds. The north tower registered a tremor of 2.3 and
came down in slightly over 8 seconds. The pattern registered for 1 and 2 indicates a series of bombs were detonated in cadence with the last explosion
being the largest charge. The pattern registered by the fall of WTC 7 is significantly smaller in magnitude and is the signature of a conventional
