Per,
The fact that the Earth seems flat does not mean that it is flat or ever was despite of centuries of false claims. So the spikes!
Hot spots in basements are understandable, because the fires in basements and in rubbles were without cooling, so temperatures had to rise there. Fires in shafts are understandable, because jet fuel flown there. Everything seems to be correct.

Donald,
Please, do not take this cartoon literarily, as the explanation of the whole mechanism. It illustrates only one aspect, but all lies in the calculations, and – first of all – is illustrated by the schematics showing sizes of the outlined impact holes in WTC 1 and 2 elevations.

Would you write, please, what is the syntax of inserting of my cartoon into your posting? I had tried above writing [img]http://groups.msn.com/_Secure/0YQDrAlYgbHGVQllhuTTvUFg8hHHStuLS9ZcmbVDLRT9KPfmlNjg4pZMfRYKqJD3h70M0eRcNKwMSP2OM*Au3nyPi7EzqdRywmCQTB6q2JUXI!x1k17EMWLvfgyxTINiR*r78Y64JCRj!XltITro4Aw/collapse.gif?dc=4675487510967116596[/img], but it did not work. What should be written between the marks “img” and “/img”, or what did you write between them, please?

Donald,
Thanks, and I meant “…but all lays in the calculations” and not, as mistakenly written “lies”.

Kevin,
Please explain, how the “Img” button works for inserting a picture into a post. It seems not working, because the location between the marks for the picture that follows is correct, but does not result in displaying it. Why?

A vigorous discussion about a conspiracy among officials within US took place at http://portland.indymedia.org/en/2004/09/296788.shtml. There must be reasons for such a theory indicating a strong resentment against the officials here, and what they represent. Prejudice is really very sad.

The NIST report "Project 6 - WTC 7 Structural Fire Response and Collapse Analysis" available at http://wtc.nist.gov/pubs/June2004WTC7StructuralFire&CollapseAnalysisPrint.pdf. It explained nicely, what is a mechanics of the collapse that was visible (how happens that, what can be seen on recordings), but does not say a word, what happened in the time between WTC 7 got hit by debris from falling WTC 1 at 10:29 until the first unspecified fire reports at 11:30, i.e. an initial progression of fires, and nothing also showing a connection between the fires and the collapse, so still not much, but more than by FEMA, which was not difficult to achieve, and cannot be congratulated, considering that, what FEMA did was a joke, but - hey - a little progress has to noticed: - "Good" job NIST; twenty more years, and we will know, what really happened in WTC 7... maybe.

http://www.wirednewyork.com/wtc/7wtc/default.htm provides:
Quote:
"Falling debris also caused major structural damage to the building [WTC 7], which soon began burning on multiple floors, said Francis X. Gribbon, a spokesman for the Fire Department. By 11:30 a.m., the fire commander in charge of that area, Assistant Chief Frank Fellini, ordered firefighters away from it for safety reasons."

and
Quote:
"The manager of the building when it collapsed, Walter Weems, said the larger tank sat on a steel-and-concrete pedestal on the second floor and held 6,000 gallons of diesel fuel. He said an even larger cache, four tanks containing a total of 36,000 gallons of diesel fuel, sat just below ground level in the loading dock near the southwest corner of the building."


http://www.whatreallyhappened.com/WTC/7WTC.html provides:
Quote:
"Fire Department officials warned the city and the Port Authority of New York and New Jersey in 1998 and 1999 that a giant diesel fuel tank for the mayor's $13 million command bunker in 7 World Trade Center, a 47-story high-rise that burned and collapsed on Sept. 11, posed a hazard and was not consistent with city fire codes. The 6,000-gallon tank was positioned about 15 feet above the ground floor and near several lobby elevators and was meant to fuel generators that would supply electricity to the 23rd-floor bunker in the event of a power failure. Although the city made some design changes to address the concerns - moving a fuel pipe that would have run from the tank up an elevator shaft, for example - it left the tank in place. But the Fire Department repeatedly warned that a tank in that position could spread fumes throughout the building if it leaked, or, if it caught fire, could produce what one Fire Department memorandum called "disaster."

The New York Times 10/20/04 article "Study Suggests Design Flaws Didn't Doom Towers" at http://www.nytimes.com/ads/carrotink/CarrotInkApril28.html should be actually read "Study Suggests [Incorrectly] Design Flaws Didn't Doom Towers", because of its following quotes:
Quote:
The findings by the institute, however, still do not exonerate Mr. Robertson or the building's owner, the Port Authority of New York and New Jersey, which, [...] boasted that the design was so robust that the towers could be hit by a jet traveling at 600 miles per hour without collapsing or endangering the lives of occupants beyond the impact zone. In retrospect, such a claim was unjustified because the engineers had failed to consider the added stresses caused by the resulting fires.

Quote:
The tentative conclusions by the federal investigators conflict with an earlier report by a team of structural engineers organized by the Federal Emergency Management Agency, who had asserted that the collapse of the north tower started in the core, not in the outer columns.

Quote:
But James G. Quintiere, a professor of fire protection engineering at University of Maryland, said he questioned the tentative conclusions, as his analysis showed that in the fires created by the impact, the lightweight floors rose to a temperature high enough to make them separate from the exterior columns. "They have not presented enough evidence," he said.

FEMA not only misrepresented the collapse, but actually lied about it. See the difference between the false truss end containing a stable triangular mesh (actually not present) by FEMA on Fig. B-8 at http://www.fema.gov/pdf/library/fema403_apb.pdf, and the actual end containing sometimes unstable quadrangular mesh by NIST on page 8 at http://wtc.nist.gov/pubs/June2004StandardFireTests.pdf, on page 18 at http://wtc.nist.gov/pubs/June2004ThermalInsulationMethodology.pdf, and clearly visible on the picture on page 36 at http://wtc.nist.gov/pubs/June2004StructuralFireResponseandCollapseAnalysis.pdf (or mesh-bad.gif versus mesh-bad.gif, mesh-ok.gif, mesh-okPh.jpg at http://groups.msn.com/FEMAmisledthepublicabouttheWTCcollapse/figures.msnw?Page=2; see also below).

FEMA actually provided the right explanation of cause of the WTC collapse in its Study’s Appendix B on pp. B7-B8 quoted below. It is a masterpiece of deception, because the explanation is quite unnoticeable (especially without missing words added by myself in the brackets), while the front conclusion - criticized in the article above - is obviously unreasonable even for a child.

So - on one hand - FEMA sneaked the right explanation (which directly points at faulty design, because 56 or 103 min. fire should not have disjointed and caused buckling of external columns) nobody wants to see officially, and only a few can understand, so FEMA cannot be blamed for incompetence, and - on the other hand - the FEMA’s unreasonable front explanation does not blame the structural designer for providing the unacceptable design nor the Port Authority of NY & NJ for approving such a design and issuing the building permit to construct the faulty WTC towers, so frontally FEMA does blame anyone home.
Quote:
As the columns lose lateral support [because fire causes column-floor connections to break off] and deform out-of-plane [or buckle] from overloading eccentricities [or shift off center of load, because by loosing one floor connection a column doubles its unsupported height quadrupling its whippness resulting in bending by the same load pressing more supple column now much easier to bend being less stiff after loosing one floor connection] and from the thermal effects [of fire], the bending moment acting on the column splice [end plate connection] does not introduce significant forces into the bolted end plate connection until the eccentricity exceeds 2 inches. As the eccentricity increases [from thermal effects], the applied bending moment will exceed the bolt preload stress when the eccentricity reaches approximately 4 inches. Continued deformation will exceed the ultimate moment capacity of the connection and result in instability as the eccentricity approaches 4.5 inches. It also should be noted that the column splices were staggered mid-height at each floor, as was illustrated in Chapter 2. As a result, two-thirds of the perimeter columns were continuous at each floor's mid-height elevation. This resulted in staggered failure patterns, as the bolted end plate connections and spandrel beam connections failed during the resulting instability and collapse.

WTC 2 collapsed twice as fast as WTC 1 not because of a greater structural damage – as FEMA claimed – but because of thermal effects of floor heated by fire causing structural disintegration and progressive, destructive (non-elastic) wobbling of the towers’ parts above the impacts.

Wobbling of the WTC 2 part above the impact - twice as high as in WTC 1 (WTC 2 was hit twice as low from the roof as WTC 1) - required a half of amplitude (angle) to shift roof sideways by the same distance (overloading eccentricity), and to break it.

It actually is visible on a PowerPoint slide show made of every 12th frame of 368 frames (12.3 sec. at 30 frames/sec) of the collapse starting at 35:05 of the “WORLD TRADE CENTER Anatomy of Collapse” (by TLC and available on DVD) extracted using PowerDVD.

For some of those against the war on terror, maybe it would help if they would start running those videos of those airplanes crashing into the World Trade Towers again. Shocked

Donald,
Do the orphans and widows of the died 343 firefighters, 60 police and 182 other victims all below the impact have a right to know the truth and seek justice including suing the Port Authority of NY & NJ (outside of city safety codes) and the structural engineers for negligence (possibly even criminal) and maybe even conspiracy to neglect in verifying and making design to be safe - thus contributing to the WTC collapse, because they wanted to make a few bucks (keep their jobs), but they did not want to or could not put a sufficient effort to earn them honestly, please?

A lack of freedom of expression has been a foundation of totalitarian societies. Would you like people to shut up, if you disagreed with them, or their subject was inconvenient for you or just not supporting your current objectives, please?

Do you really think that everyone’s set of objectives is the same as yours, and if not, he automatically is an enemy to anything obviously right, like war on terror only, because you are for it, and you do not share certain other objectives of his (like truth and justice for everyone incl. Bin Laden, Port Authority, structural designers, etc.), please? Do you really think that there is only one set of objectives for everyone? Do you really think that, if someone was not with you (100 %), he must be against you (against war on terror you stand for), please?

Richard Haut gets carried out a little bit, but does he really have to take medication talking about Philip Johnson’s fascism for at least 8 years of his adult life, because of, e.g. Richard’s lack of familiarity with Louisiana specifics, please?

De gustibus non est disputandum!

Yes and lets not forget where we got those freedoms of speech and press... oh one who has posted this topic for the umpteenthed time. Think about this. What phrase do many leftist use to describe the expression of conservative ideas and concepts. You've heard them. It's "hate speech." On many college campuses around the nation there are active movements to have the expression of conservative ideas branded as "hate speech" and banned on campus. For example: expressing opposition to that government-enforced program of systematic racial discrimination known as "affirmative action" is condemned as "racism."

I understand, my friends. There are many things that both you and I read here may offend our sensibilities. Let's recognize and accept our individual responsibility for what we read and what we write, and let's forego our politicial aggessions and stop using the heavy hand of this forum as a method of pandering.

.....and maybe even conspiracy.....

And ohhhhhh .. the conspiracies! You just wouldn't believe the wild conspiracies some people are spouting. I listened to one character pontificate to a crowd at length about the attack on the World Trade Towers once. I really didn't understand all that he was saying .... but I think it had something to do with asbestos. Somehow I thought this character was telling the crowd that George Bush had the World Trade Towers attacked because they contained asbestos and it was easier to just bring them down like that, then it would have been to actually clean up the asbestos and it was all some sort of a favor to the people who owned the buildings and all that. The people who owned the buildings? The people of New York owned the buildings! A Republican president is doing favors for the people of New York?

And so it continues on and on....like an obnoxious broken record....will we ever get over blaming the owners, structural engineers and all those involved in the design of the WTC towers for this disaster of unpredictable proportions...and what about the designers of the Pentagon? Should those walls have withstood the impact of a jet airliner?

America was targeted because we're free and because we repeatedly show that we can change our own leadership without violence, without bloodshed and turmoil. Leadership changes make the mullahs nervous. America was targeted because we are a nation that demonstrates, day after day, how many different religions; Christianity, Judaism, Islam, Hinduism; can live and prosper together. We were targeted because we have shown the world that a rule of law, not the mindless and cruel dictates of a religious cult, can protect the peace and ensure the harmony of people of all faiths living together in liberty. We were targeted, and we remain a target, because we've been on a roll for over 400 years and still haven't reached our peak --- while Islam reached its cultural dominance 500 years ago and it's been pretty much been rocketing down a mud slide to hell since then. Shocked
