New Twin Tower Collapse Model Could Squash 9/11 Conspiracies

Editor’s Note: Even if this new explanation is valid (stretching our imaginations to the limit), how can it be accurately applied to Building 7? Please read Michael Rivero’s critique of this theory.

Many 9/11 conspiracy theories revolve around explosions that were seen and heard in the World Trade Center’s Twin Towers prior to their collapse. Despite scientific investigations that have explained the processes that brought down the skyscrapers, some conspiracy theorists suggest the plane impacts were just red herrings, to distract from the fact that 9/11 was an “inside job” — that explosives had been implanted earlier in the World Trade Center buildings and were what really brought them down.

Now a materials scientist has come up with a more scientific explanation for the mystery booms, and says his model of the Twin Towers collapse leaves no room for conspiracies. “My model explains all the observed features on 11th September: the explosions, molten metal coming out of the window, the time passing between the crash and the collapse, the fact that the explosions took place in a floor below the place it was burning, and the rapid collapse,” Christen Simensen of SINTEF, a research organization in Norway, told Life’s Little Mysteries.

As detailed in the new issue of Aluminum International Today, Simensen argues that molten aluminum from the airplane bodies chemically reacted with water in the buildings’ sprinkler systems, setting off the explosions that felled the Twin Towers.

Chain of events
When each jet cut its way into a building, it took with it parts of walls and ceilings, Simensen said. Steel bars in those walls would have gashed its fuel tanks, which would have caught fire. With the plane positioned somewhere in the middle of the building, blanketed in debris and with no route for heat to escape, the temperature would have rapidly escalated, reaching 660 degrees Celsius (1,220 degrees Fahrenheit), the melting point of aluminum — of which there was 30 tons in each plane fuselage — within an hour. The molten aluminum would then have heated up further to between 800 and 850 C (1,470 and 1,560 F).

“Then molten aluminum becomes [as liquid as] water and has so much heat that it will flow through cracks in the floor and down to the next floor,” Simensen explained in an email. There was an automatic sprinkler system installed in each ceiling, and it was filled with water. “When huge amount of molten aluminum gets in contact with water, a fierce exothermic reaction will take place, enormous amount of hydrogen is formed and the temperature is locally raised to 1,200 to 1,500 C,” or 2,200 to 2,700 F.
