Countless experts have already done this, but because they don't see any evidence that the buildings were brought down by explosives, they must all be "in on it".
So thousands of scientists at civil engineering departments and at NIST and Scientific American and Popular Mechanics and Skeptic are all "in on it".
It is very easy to quote "countless experts have done this". List me their name, their claim, their published work etc. Tell me frankly, you could have read Scientific American, and can you tell me which MIT professor that Scientific American quote regarding the tower collapse? If you know which professor, have you actually read who he has written? If you have, then I shall point out the relevant part why this professor could be "in on it", or he is simply stupid and try to make a name for himself, in the same class as Steven Jones, one supporting the government, one trying to pull the leg of the government.
Have you read the complete article of Scientific America, and the paper in Popular Mechanics, or the book by Popular Mechanics. Are you perfectly happy with the arguement? Have you read any counter arguement to those two Government propaganda article?
Those countless experts did not see explosive evidence is because they refused to see it. Like the three monkeys, see no evil, hear no evil, and speak no evil. They need their comfort zone to survive, or else they will go crazy. They are also very lazy. They do not investigate whether the total amount of heat energy available from the plane striking and the burning fuel (some even claim furniture can produced large amount of heat) is enough to rasie the temperature of the steel to the point of failure. Most government supporting scientist never consider the heat lost, the very good heat conducting nature of steel etc.
To give an analogy, which is not scientifically exact as in the case of WTC burning, you use gas burner to cook your food, or boil water. What is the hottest temperature of the flame? What is the hottest temperature reach by the kettle before boiling? Which part of the kettle is hotter than the others?
You should note that the gas burner flame is very close to your kettle in order to be able to heat it up effectively. Now the burning of the spilled kerosene from the plane, how do they burn? By gravity they have to lie level on the floor (subject to being contained in by other obstructing things into a pool), how tall do you think this flame can be? Have you attended fire fighting exercise, where petrol was place ontop of a tank of water, ignited, and your demonstrator using a fire extinguisher to put it out? So this burning pool of kerosene has to be really a huge flame in order to heat the floor on top, where the insulating material has been knocked off by the impact, so claimed the NIST.
Now even if we have good heating, the steel columns, beams etc are interconnected, and heat can be conducted rapidly away to other members.
The you have to know the thermal conductivity of steel, and find out the cross sectional area to calculate the heat flow from this heated member to the neighbour etc. The higher the locally heated member, the faster will be the heat conduction away, and temperature may not rise without levelling out! Then you have the radiation heat lost, and the convective heat lost.
Try to think about it. Those other tall building that burned for days would have the interior reached much higher temperature than that in WTC.
The dense black smoke indicate the peak combustion is over. There is no shortage of oxygen in the case of WTC, since the plane has plowed and created holes from one side to the other in one tower, and though the other tower only has a huge opening in the entrance, other windows and structures were also shattered, so that there is no shortage of free flow of supply of oxygen for the burning. In fact, if we can have all the information available, we can calculate when the kerosene fuel was completely consumed by making certain assumption, and it should be accurate to within 10 minutes of time frame.
Now back to your expert, if you know who he is, the MIT professor. He said he did not know how much fuel the plane was carrying, so he has to make an assumption of 3/4 tank, half tank etc. So can you see how non-scientific this professor can be? He could try to get the information, as the airport certainly must have record of how much fuel in the tank of the plane before taking off. I think either he was negligent, or he tried, and then the government told him to be non-commital, and just take a guess. Or esle, there is a conspiracy of the government refusing to let a scientist have all the facts to make his study. Still think there is no conspiracy?
