The September 11, 2001, attack on the World trade center

Today, as I am writing these notes, is September 11, 2006. We all remember that fright filled day five years ago, when so many lives were lost, and we thought the world was destined to end.
Here is a re-look at an article I posted at that time.

In recent articles at this forum, we have discussed conspiracy theories related to the September 11, 2001, collapse of the World Trade Center. There was some discussion of structural weaknesses in the twin towers.

Collapse of the two towers

The north tower, 1 WTC, was struck at 8:46:26 am and collapsed at 10:28:31 am, standing for 102 minutes 5 seconds after impact. The south tower, 2 WTC, was struck at 9:02:54 am and collapsed about 56 minutes later, around 10:00 am. According to the 9/11 commission report, "at 9:58:59, the South Tower collapsed in ten seconds, .... The building collapsed into itself, causing a ferocious windstorm and creating a massive debris cloud."
Immediately after 9/11, experts began to offer opinions as to what caused the buildings to collapse. British structural engineer Chris Wise commented that "It was the fire that killed the buildings. There's nothing on earth that could survive those temperatures with that amount of fuel burning. The columns would have melted, the floors would have melted and eventually they would have collapsed one on top of each other."

Some have referred to a "Third Tower". This, I surmise, refers to Seven World Trade Center, a 47-story steel-frame skyscraper across the street from the rest of the complex.

T C 7

Building 7 was the third skyscraper to reduced to rubble on September 11, 2001. According to the government, small fires leveled this building, but fires have never before or since destroyed a steel skyscraper.
The team who investigated the collapse were not allowed access to the crime scene. By the time they published their inconclusive report, the evidence had been destroyed.
Why did the government rapidly recycle the steel from the largest and most mysterious engineering failure in world history, and why has the media remained silent?

A more recent investigation into that collapse follows:

The WTC complex had seven buildings. The third building to collapse was 7 WTC, which fell at 5:20 pm, as seen live on television. 7 WTC was a 47-story steel-frame skyscraper across the street from the rest of the complex.
The 2 million-square-foot building, 7 World Trade Center, had suffered mightily from the fire, and had been wounded by beams falling off the towers. But experts said no building like it, a modern, steel-reinforced high-rise, had ever collapsed because of an uncontrolled fire. They have been trying to figure out exactly what occurred, and whether they should be worried about other buildings like it around the country. – Chicago Tribune, November 29, 2001

As part of the electrical backup system, there may have been up to 160,000 l (42,000 gallons) of diesel fuel stored in five tanks within the building on several floors, as well as pumps to distribute it. It has been claimed that the diesel fuel and emergency generators spilled and ignited inside building 7. Another speculation is that the building's unusual architecture may have contributed to its collapse. Theoretically, cantilevers and structural members, required to transfer building weight off of the pre-existing Con Ed electrical substation that 7 WTC was built over, may have failed in the fire leading to the internal mechanism of collapse.
