We know much about that day. We know about the deaths. We know about the controversy surrounding the official story and actual evidence. We know how our society changed abruptly.
What is interesting to me, as an engineer with over 20 years experience and having conducted countless forensic investigations, is how few people can see 1.2 million tons of concrete (3 buildings in total) turned to powder in 8 seconds and not wonder where all that energy came from.
Where is the seismic data showing what happens to the earth when a 500,000 ton pile of steel and concrete falls to the ground at near free fall speeds? We actually have bench marks to draw from on this topic because many large buildings have been collapsed--so we know what is suppose to happen.
Most engineers know that the study of blowing things up is a mature area of research. There is lots of data. Many men love blowing things up. We can calculated the velocities of a shock wave from photos; we can calculate the energy needed to create the kind of event that took place on 911.
The problem is that using conventional physics and trying to fit the known data from that day into these models doesn't work. No one has been able to do it! And no one has tried harder than NIST who have considerable resources to throw at this problem.
Dr Judy Wood is the only person to present a rigorous examination of the evidence. She has written the most important book of this century on the topic ("Where Did the Towers Go?").
Finding insignificant flaws in some the data on her web site doesn't disprove the gnawing problem that there was virtually nothing left of the towers within seconds of the start of the catastrophic failures.
9-11 It is impossible to go into all of the evidence here. I could but her web site ( www.drjudywood.com/ ) is easy to find and easy to follow. She has done countless interviews. No one has yet to refute one piece of evidence given in her recent book. People have undertaken ad hominem attacks, but that just proves that they don't have anything to say about the evidence.
Here is a small sample of the unexplainable characteristics of the WTC collapse, taken from Judy's site:
The Twin Towers were destroyed faster than physics can explain by a free fall speed "collapse."
They underwent mid-air pulverization (dustification) and were turned to dust before they hit the ground.
The seismic impact was minimal, far too small based on a comparison with the Seattle King Dome controlled demolition.
The Twin Towers were destroyed from the top down, not bottom up.
The upper 80 percent, approximately, of each tower was turned into fine dust and did not crash to the earth.
The upper 90 percent, approximately, of the inside of WTC7 was turned into fine dust and did not crash to the earth.
One file cabinet with folder dividers survived. No toilets survived or even recognizable portions of one.
Windows of nearby buildings had circular and other odd-shaped holes in them.
Evidence of molecular dissociation and transmutation, as demonstrated by the near-instant rusting of affected steel.
Weird fires. The appearance of fire, but without evidence of heating.
Lack of high heat. Witnesses reported that the initial dust cloud felt cooler than ambient temperatures. No evidence of burned bodies.
Office paper was densely spread throughout lower Manhattan, unburned, often along side cars that appeared to be burning.
Approximately 1,400 motor vehicles were towed away, toasted in strange ways, during the destruction of the Twin Towers.
Dr Judy Wood's book will change the world. It is easy to see from her photographic evidence that nothing about that day matches our limited understanding of the laws of physics. This means something extraordinary to the planet. It means that a technology exists and is being used at this time in a very destructive way, which is different from anything we have seen before. Imagine, if we used this knowledge in a constructive way.
