PARIS - A mix of sprinkling system water and melted aluminum from aircraft hulls likely triggered the explosions that felled New York's Twin Towers on September 11, 2001, a materials expert has told a technology conference.

"If my theory is correct, tonnes of aluminum ran down through the towers, where the smelt came into contact with a few hundred litres of water," Christian Simensen, a scientist at SINTEF, an independent technology research institute based in Norway, said in a statement released Wednesday.

"From other disasters and experiments carried out by the aluminum industry, we know that reactions of this sort lead to violent explosions."

The official report blames the collapse on the over-heating and failure of the structural steel beams at the core of the buildings, an explanation Simensen rejects.

Given the quantities of the molten metal involved, the blasts would have been powerful enough to blow out an entire section of each building, he said.

This, in turn, would lead to the top section of each tower to fall down on the sections below.

The sheer weight of the top floors would be enough to crush the lower part of the building like a house of card, he said.

The aluminum -water scenario would also account for explosions from within the buildings just prior to their collapse that have fuelled conspiracy theories suggesting that the structures had been booby-trapped.

Simensen presented his theory at an international materials technology conference in San Diego, California, and has detailed his calculations in an article published in the trade journal Aluminum International Today.

"The aluminum industry had reported more than 250 aluminum -water explosions since 1980," he said.

In a controlled experiment carried out by Alcoa Aluminum , 20 kilos (44 pounds) of molten aluminum was allowed to react with 20 litres of water, along with a small quantity of rust.

"The explosion destroyed the entire laboratory and left a crater 30 metres (100 feet) in diameter," Simensen said.

By comparison, the aircraft carried 30 tonnes of aluminum into each of the towers, according to his calculations.

Simensen speculates that the two commercial jets were immediately trapped inside an insulating layer of building debris within the skyscrapers.

The debris — especially plaster, which blocks the transfer of heat — would have formed a shield protecting the rest of the building.

At the same time, however, it would created a super-hot, oven-like zone around the aircraft, heated by burning fuel.

Aluminum alloy, which in jet hulls also contains magnesium, melts at 660 degrees Celsius (1,220 degrees Fahrenheit). If heated to 750 C (1382 F), the alloy "becomes as liquid as water," Simensen said.

This molten aluminum could then have flowed downward through staircases and gaps in the floor, causing a chemical reaction with water from sprinklers on the levels below.

The mix would immediately boost temperatures by several hundred degrees, releasing combustible hydrogen in the process. Such reactions are even more powerful in the presence of rust or other catalysts, which can boost temperatures to more than 1,500 C (2,700 F).

A meltdown period of 30 to 45 minutes would also be consistent with the timing of the explosions and subsequent collapse of both buildings in relation to the moment of impact.

Simensen said there are lessons to be learned, if his theory is correct, that could help avoid a similar disaster were another skyscraper to be hit by a big jet.

"We could develop means of rapidly emptying sprinkler systems in the floors beneath the point of impact," he said.

Firing a rocket with fire-retardant that could coat the aircraft body could also help prevent metal alloy from melting.

I knew the hole meant the remaining columns held extra weight..but yea good one.
Good pic too.No offence meant of course.

[GODREKR]

Bull-fucking-shit!

[Eaton]

Good one. Try again.

[sassieroses]

Interesting theory

Firefighters on the scene claimed to see large pools of molten metal, this theory explains how that may have been possible. However it still doesn't explain why the beams of the internal structure were cut the same way it's done for a controlled demolition. The only way of cutting those beams at the angle they were cut is to use thermite demolition charges. The beams used in the central core had a high fail point temperature, and the towers were designed to survive impacts from aircraft. How about building 7 which was not hit but still came down anyway? Video footage shows a controlled demolition occured on building 7. Thanks to the CT nuts we have the best theory of what really happened that day. I won't even go into the fact that about half a dozen of the so called 'terrorists' that were blamed for this are still alive.


Good post anyway, now more people understand that aluminium can become a potent explosive too.

concerning tower 7
take into account the sheer size and weight of towers four and five and that when they fell they registered as an earthquake down here in wellington nz
i think thats what caused that fucker to drop

But the buildings surrounding it were almost untouched, maybe a few broken windows and that's it. The footage has been shown to demolition experts and they say it looks exactly the same as a controlled demolition. First it sags in the middle and then falls in on itself. Way too many coincidences on that day to believe the shit being force fed to us by the media.

Oh man I am such a Conspiracy buff, I won't even begin to start. Interesting view from the guy in Paris, but it's irrelevant. Any American with half a brain and some minimal access to the internet or hell, even History Channel, will gather their own opinion about 9/11/01. I still to this day think every single bit about that day and the years that still continue to follow it are bullshit.

Good find though! Nothing against the creator of this thread about my opinion. And I agree with Blewvane, there is a documentary the USA keeps shutting down and I watched it on a friend's dvd he'd made, if I remember what it's called or find it I'll upload it or pass around the name. However, what I'm getting at is a Private Canadian investigation team went in to prove 9/11 was a fake and they talked to a demolition specialist who said that Building 7 was marked for demolition for 3 weeks prior to 9/11, but that they had been paid exceeding amounts to never file paperwork on it.

thereby replicating the effects of an earthquake
we had buildings here that were dropped by the earthquake in February yet their neighbours so to speak were relatively untouched
mehh who knows though
