The 9/11 Truth Movement has gotten extremely complicated and confusing with all of the different perspectives and interpretations of vast amounts of data resulting from the bizarre events of that day. Some of which is neither correct nor important, so inevitably a lot of people dismiss the movement as a bunch of kooks which, unfortunately, some of them are.
So I propose a little thought experiment to simplify things a bit.
Imagine that we have WTC2, the south tower, intact as it was on Sept 10, 2001. Since the plane impacted at the 81st level of the building let's completely remove FIVE LEVELS of the building, 79, 80, 81, 82 and 83. Since each level of the building was 12 feet in height this would leave a 60 foot gap between the top of the 78th level and the bottom of the 84th.
Now that is far more damage than the airliner could possibly do. It eliminates any debate about how hot the fires were and whether they could weaken the steel. Obviously there is not point in discussing fake planes.
The formula for distance from acceleration and time is:
d = 1/2 a t^2
Since gravitational acceleration is 32 ft per seconds squared the data for this problem yields:
60 = 16 * t^2
Therefore the time is about 2 seconds.
1.936491673 sec = t
So the intact upper 27 levels would take 2 seconds to fall and impact the intact lower 78 levels. The formula for velocity from acceleration and time is:
v = a * t
Which for these values yields:
64 ft/sec = 32 ft/sec^2 * 2 sec = 44 mph
Since each level of the World Trade Center was 12 feet the top of the 78th level was:
78 levels * 12 ft/level = 936 ft
Now if the falling 27 stories could maintain a constant velocity from the moment of impact until it reached the ground it is easy to compute how long that would take.
936 ft / 64 ft/sec = 14.625 seconds
If the bottom 78 floors prevent the top from accelerating but crumple at a constant velocity it would take 15 seconds to crush 78 floors. Since the building came down in 11 seconds the top had to crush the bottom and accelerate at the same time. A truly amazing feat.
Are we supposed to believe those 78 level would not cause the falling mass to SLOW DOWN?
What is going to happen the instant the bottom of the 84th level comes in contact with the top of the 78th? They are going to engage in a mutual crushing of steel, concrete and office furniture that would be deadly to behold. But where is the energy to do that crushing going to come from? It is going to come from the kinetic energy of the falling mass. Which means the falling mass is going to SLOW DOWN. It is going to DECELERATE. It is going to undergo NEGATIVE ACCELERATION. Which means it must take longer than 15 seconds to reach the bottom, if it ever does.
But to come up with anything vaguely resembling an accurate analysis of this simplified thought experiment we would have to know the
TONS of STEEL and TONS of CONCRETE on every level of the WTC. The expected and maximum loads for each level would probably help too. That would tell us how over-engineered the building was and the extra energy necessary to crush it. Since the people who designed the World Trade Center way back in the 60's, when computers still had CORE MEMORY, it is certainly amazing that our
EXPERTS don't even raise such childishly simple questions in these days of laptop supercomputers. The NIST report mentions the total amount of steel in the towers three times but NEVER SPECIFIES the total amount of concrete though it says two types of concrete were were used.
Some people accuse the "conspiracy theorists" of not understanding the difference between static loading and dynamic loading as though the difference is going to cause the overloaded material to burst into dust. But we are dealing with a material state with inputs applied and a known output of a TOTALLY DEMOLISHED BUILDING. The known input is a 150 ton plane with 34 tons of kerosene traveling at 500+ mph. How can we claim to know the state of the material if we don't know the
TONS of STEEL and TONS of CONCRETE on every level. The believers in the official story demand proof of an energy input besides the plane but don't demand accurate information about the subject of the destruction. You can't do an analysis if you don't know what you are analyzing.
The fires alone add a really complicated factor to the mix. A simulation of the missing 5 levels would probably be less complicated than the plane impact and fires. But if that simulation doesn't crush the building to the ground then all of the claims about the plane and fire doing it go out of the window.

It is astounding that the nation that put men on the moon will tolerate crap like that.
NIST & PBS NonsenseSo until we can get such simple information as the
TONS of STEEL and TONS of CONCRETE on every level then talking about fake planes, beam weapons and nuclear devices is absurd because we really don't have an accurate understanding what it was that was destroyed.
