9/11 Debate

[LP]

Not the one I was looking for but the statement about the the designers not expecting 90,000L of jet fuel on one floor was what I remember, Ill keep looking though for the what I was looking for. Some other pertinent points are made about why the buildings fell straight down.

To handle these immense forces, the engineers "designed the World Trade Center essentially as a large beam section," explained another panel member, Robert McNamara, president of the engineering firm McNamara and Salvia.

Newspapers and TV newscasts reported that the twin towers had been designed to withstand a collision with a Boeing 707. The events of September 11th show that this was indeed the case. "However, the World Trade Center was never designed for the massive explosions nor the intense jet fuel fires that came next a key design omission," stated Eduardo Kausel, another M.I.T. professor of civil and environmental engineering and panel member. The towers collapsed only after the kerosene fuel fire compromised the integrity of their structural tubes: One WTC lasted for 105 minutes, whereas Two WTC remained standing for 47 minutes. "It was designed for the type of fire you'd expect in an office building paper, desks, drapes," McNamara said. The aviation fuel fires that broke out burned at a much hotter temperature than the typical contents of an office. "At about 800 degrees Fahrenheit structural steel starts to lose its strength; at 1,500 degrees F, all bets are off as steel members become significantly weakened," he explained.
