Aviation fuel will not melt steel, the "weakened by fire" point has been proven, not just in scientific models but also in real world evidence whenever there is a major fire in an office-block that does not result in a collapse.
Large chunks of concrete would still survive. Instead, each floor was almost entirely pulverized to dust long before it hit the ground. That degree of destruction can be explained only by high-explosives.
there are tons of engineers who will look at you and go the fire wasnt hot enough to explain the molten steel pouring out of the side of the building jet fuel alone and office supplies do NOT burn hot enough to do what your saying its been proven....and they are the first steel structure's to actually "collapse" because of fire...please if your so inclined tell me why a building that burned for 18hours straight stayed standing...it must of went threw way more hell Considering it burnt for 18hours over what 54 mins? you say your wife is an architect.....well then even she could tell you she didnt know for a fact it would come down...or the fact she really thought it would since a fire has NEVER taken a steel structure down..... i would love to argue every point of your new found belief but it would be pointless.
actually most of the jet fuel burned off within a few minutes according to FEMA, and NIST didn't find evidence of fire damage over 250C. not surprising since most of the rubble was thrown away and melted down in a few weeks. 80% of the steel was never examined.

the fires (from the planes and office stuff alone) were only half the temp. needed to weaken the steel to failure.
The World Trade Center Construction manager says that the WTC was designed to withstand the impact of a fully loaded 707 (which was the largest plane at the time) and that such an impact would to nothing to the structural integrity of the building.
goes on to say the buildings could actually take multiple planes..
the top floors were weakened as heat rises. the bottom floors were more sturdy and had a much greater mass. the force of gravity was pulling on the upper floors, but the lower floors were providing an equal and opposite reaction much greater than the top floors were generating. truth be told, the top floors shouldn't have fallen at all, but even if they did, they would have been destroyed before they demolished their weight, and the energy would have dissipated, just as newton's third law states.
The fire wasn't hot enough to do the least bit of damage to the 46 verticle steel standing columns that ran through out the height of those buildings. The collapse we see is simply impossible. I said impossible as an ironworker.
I know this for a fact. 20 years in the trade.
Very smart men were behind these attacks. Men that use their intellect to attack your intellect. Do you know what sounds like a crazy conspiracy theory? 19 Arabs with box cutters took over 4 jets and evaded the most sophisticated defense network in the world while under the command of a guy living in a cave with a laptop and flew 2 jets into the WTC and managed to knock down 3 buildings while another jet was flown with amazing precision into the Pentagon.
If you believe the official account of 9/11, you are a deluded half-wit.
Bush is guilty of this crime, the American government planned this to start the war on terror in the middle east. They allowed it to happen and one day we will find out they did this to their own country .. This is very disturbing to me that the USA will kill thousands of people in order to give them a reason to start a war in Iraq.
