“[Building designer] John Skilling recounts his people having carried out an analysis which found the twin towers could withstand the impact of a Boeing 707. Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed.” But, he says, “The building structure would still be there.”
“The analysis Skilling is referring to is likely one done in early 1964, during the design phase of the towers. A three-page white paper, dated February 3, 1964, described its findings: “The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC 8) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.” However, besides this paper, no documents are known detailing how this analysis was made.”
“Leslie Robertson, one of the two original structural engineers for the World Trade Center, is asked at a conference in Frankfurt, Germany what he had done to protect the twin towers from terrorist attacks. He replies, ‘I designed it for a 707 to smash into it,’ though does not elaborate further.”
[Leslie Robertson:] “The twin towers were in fact the first structures outside the military and nuclear industries designed to resist the impact of a jet airplane.”
[Frank A. Demartini:] “The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting.” Frank A. Demartini, on-site construction manager for the World Trade Center, spoke of the resilience of the towers in an interview recorded on January 25, 2001.
I call you're attention to the roughly 10-story tall gash in it. That gash went in about a quarter of the way. This gash destroyed many structural columns that were keeping the building up. Every column was responsible for about 2,000 square ft. of office space. Now, consider that the gash began pretty close to the ground floor. What would this lead to? Taking into account the fact that each column was responsible for many tons of wieght, and that the fires burned at a hot enough temperature to cause the steel to lose close to 50% of its weight, catastrophic failures occured vertically. When it reached the top, this caused a chain reaction that any simple cretin would mistake for a controlled demolition.
1. Were they just lucky? Did they plant thermite charges in that building just in case, and it paid off?
2. Did they hedge their bets? Did they *start* the fires? Were explosives used to make building 7 appear damaged by towers 1 and 2?
3. Did they plant bombs in all the surrounding buildings with the thought that they would bring any of them down that took damage? In other words... were all of the World Trade Centre buildings pre-rigged with explosive charges to be brought down when a convenient cover story popped up?
Lets think this through on the "Controlled Demolition" argument.

Marvin P. Bush, the president’s younger brother, was a principal in a company called Securacom that provided security for the World Trade Center, United Airlines, and Dulles International Airport. The company, Burns noted, was backed by KuwAm, a Kuwaiti-American investment firm on whose board Marvin Burns also served. [Utne]
According to its present CEO, Barry McDaniel, the company had an ongoing contract to handle security at the World Trade Center "up to the day the buildings fell down."
The company lists as government clients "the U.S. Army, U.S. Navy, U.S Air force, and the Department of Justice," in projects that "often require state-of-the-art security solutions for classified or high-risk government sites."
The World Trade Center was destroyed just days after a heightened security alert was lifted at the landmark 110-story towers, security personnel said yesterday [September 11]. Daria Coard, 37, a guard at Tower One, said the security detail had been working 12-hour shifts for the past two weeks because of numerous phone threats. But on Thursday [September 6], bomb-sniffing dogs were abruptly removed. [NY Newsday]
