1. so why didn't it topple to one side.
2. Why have larger fires in 'similar' buildings not caused the same type of decent
why didn't the towers turn into burning infernos?
but the buildings were pretty much exactly the same
The BBC found that suposed hijackers were still alive

You haven't explained how the heat got to the steel. Why didn't it melt the window frames? Why wasn't the whole thing up in flames?

Further, becasue skyscrapers are allowed to 'sway', as soon as one set of support frames are knocked away surely it would immediately begin to lean. Therefore your saying all the steel melted at within roughly the same second allowing a perfect fall.

A.It weakened the steel, which was exposed by the impact of the crash. It didn't turn it into liquid, it weakened it, enough that it failed at the critical points where the stress of the building, it mass and weight, were focused.

As you can see, the fires were pretty severe. Keep in mind that the WTC towers were four times larger than the Madrid tower.
The initial impact damaged a number of columns. The loads borne up by those columns were distributed to the other columns.

The fires would've had to have done about 4x that amount of damage to get a typical floor to fail according to NIST figures on safety factor ratings for higher floors.

Heat rises. The hot combustion gasses rose to the ceiling level, where it heated up the thin truss chords and diagonals.

As you can actually see, the fires were a orange color with alot of black smoke, similar to what you see in a burining oil well. The orange indicates a cooler flame, than a white or blue would indicate, and the thick dense black smoke indicates an abundance of fuel and a shortage of oxygen.

Due to the fact that this was a oxygen deprived kerosene fire, far from optimal burning conditions that would be required for the fire to reach the 2000-3000 degrees needed to heat the steel. Also, just the fact that the fire is that hot does not mean that everything that the fire touches is exactially that temp.

Are you talking about the failure of the floor slabs or the floor columns?

Is this your way of trying to suggest the WTC fires were worse than the Windsor Tower fires without saying it outright?

There's no evidence of widespread truss failures on a scale that would even initiate a collapse.

NIST has plenty of photographs in thier reports that document the sagging and falure of numerous floor slabs.
There's no evidence of widespread truss failures on a scale that would even initiate a collapse. You just point to the columns that "buckle" once the collapse actually starts to make up for all the ones that are missing earlier.

A total of 2,071 occupants of the World Trade Center died on September 11, among the 2,749 victims of the WTC attacks. According to an article in the October 11, 2001, Wall Street Journal, roughly 1,700 people had listed the religion of a person missing in the WTC attacks; approximately 10% were Jewish. A later article, in the September 5, 2002, Jewish Week, states, "based on the list of names, biographical information compiled by The New York Times, and information from records at the Medical Examiner's Office, there were at least 400 victims either confirmed or strongly believed to be Jewish." This would be approximately 15% of the total victims of the WTC attacks. A partial list of 390 Cantor Fitzgerald employees who died (out of 658 in the company) lists 49 Jewish memorial services, which is between 12% and 13%.
This 10-15% estimate of Jewish fatalities tracks closely with the percentage of Jews living in the New York area. According to the 2002 American Jewish Year Book, 9% of the population of New York State, where 64% of the WTC victims lived, is Jewish. A 2002 study estimated that New York City's population was 12% Jewish. Forty-three percent of the WTC victims lived in New York City. Thus, the number of Jewish victims correlates very closely with the number of Jewish residents in New York. If 4,000 Jews had not reported for work on September 11, the number of Jewish victims would have been much lower than 10-15%.
The following partial list of 76 Jewish World Trade Center victims includes many from companies that were located at or above where the planes hit. These include Cantor Fitzgerald, which lost 658 employees, Marsh & McLellan, which lost 295 employees, Aon Corporation, which lost 176 employees, and others.
First, a question begs: Where did the precise figure of 4,000 Israelis come from? According to the Anti-Defamation League's Web site, on Sept. 11, the Israeli Embassy released a statement expressing concern about the 4,000 Israeli nationals LIVING IN NEW YORK CITY—few of whom actually worked in the World Trade Center. At press time, the embassy couldn't confirm this statement.
According to Nexis and the Google search engine, the first mention of Israeli involvement in the attacks came in a Sept. 17 report on Lebanon's Al-Manar Television www.paknews.com... The Los Angeles Times reports that the terrorist group Hezbollah has free access to Al-Manar's airwaves, and the station's Web site claims that the station exists to "stage an effective psychological warfare with the Zionist enemy."
The next day at 6:26 a.m., the American Web site Information Times published an article headlined "4,000 Jews Did Not Go To Work At WTC On Sept. 11," and credited it to an "AL-MANAR Television Special Investigative Report." This was not the first time that Information Times had pointed the finger at Israel. The day after the attacks, it warned in an article that the "terrorist government of Israel … cannot be ruled out" as a suspect. Information Times purports to be edited by Syed Adeeb from the eighth floor of the National Press Club at 549 15th St. NW, Washington, DC, 20045. The Press Club says it has no such tenant and repeated messages sent to the e-mail address for Syed Abeed listed on the site bounce back as undeliverable. Directory assistance for Washington, D.C., has no listing for Information Times.
