Two airplanes that day caused two towers to collapse, people can talk about how strong the beams was and how It is impossible for the beams to
collapse or melt. However, in reality no one ever talked about the weight that the average ‘office building floor’ can withstand under pressure
What caused the damage to the North Tower on 911? My own words:
Before understanding how the “plane-shaped hole” was made in the North Tower, it is important to become familiar with the construction of the
exterior box columns of the WTC. Below is a cross-section diagram of an exterior box column from the NIST report. Pg. 125 (highlight mine):
The thickness of the steel used at the level of impact was about 3/8 of an inch. Note how the two sides protrude further than the cross section that
connects them, making them like a square tube with two knife edges facing outwards running their full length. Below is from page 62 from the NIST
report showing some exterior columns being installed:
This is what a wing would impact if a real jet had struck the tower head-on, not just dozens of steel box-columns, but dozens of box-columns with two
steel knives each. In the real world a jet would have been shredded against such a structure, with possibly the landing gear and engines containing
enough mass, energy and density of material to punch through the columns; leaving the rest of the serial-numbered and easily-identifiable aircraft
parts to fall to the streets below.
But this essay is not about whether jets were used, (they weren’t), rather I hope to put to rest a nagging question I’ve had; namely, since jets
obviously didn’t cause the damage, what did? After I got past the realization that jets weren’t used, regardless of what I saw on TV, I was left
with the awesome and awful realization that the media were and are complicit in 911, and once I reached that level of comprehension, it didn’t take
long to look at the 911 Truth Movement itself in a whole new light; and if I can’t trust the Truth Movement (I can’t), I guess I’m on my own.
I’m writing to everyone out there in the same boat.
So what did cause the “plane-shaped hole” in the North Tower?
The above image was taken from page 169 from the NIST report. Note the linear gashes allegedly caused by the wings of a jet. On the right side,
beginning below the 99th floor, the gash is pronounced and appears to have severed ten exterior columns in a straight line at about a 45 degree angle
moving to the lower left, becoming wider as it moves towards the large hole at the intersection of column 120 and floor 97.
On the left side, just above number 150 note that the columns aren’t severed. From that point, let your eye follow the gash to the right and pay
close attention to the dents on the columns. As your eye follows the damage to the right, at column 148, a dent is clearly visible on the left side
of the column, and the dents become more pronounced as you move to the right, again culminating in a larger hole where the “fuselage” struck.
Note the “knife edge” of box columns 145 and 146 in this close-up of the left side of the gash.
The damage is on the left sides of the columns, and they are bent left to right.
I was once certain the damage to the North Tower was caused by shaped charges, mostly based on page 5 of this thread, where it is speculated that a
missile was used as a first strike, and then the “plane-shaped hole” was carved by shaped charges afterwards:
Shaped charges thread
This image was particularly convincing because this gash appears to be being cut after the plane has supposedly already passed through the wall:
Here is a clip of the sequence from which the above image was taken:
But what is a “shaped charge” and does it produce the kind of explosion seen above?
Here are some demonstrations of shaped charges. I’m certain the US military has a more advanced version than say, the Discovery Channel, but
you’ll get the picture:
Shaped Charge Demo 1
Shaped Charge Demo2
Linear charge configurations are possible, as shown in this PDF.:
Linear Shaped Charges
What strikes me when I watched a few of the online videos demonstrating shaped charges cutting thick steel is that they produce a loud report, a puff
of smoke and a brief orange-yellow flash; in short, nothing like what is shown on the Naudet “footage” of the first impact from which the above
image was taken. What I now see in that image is a napalm explosion bursting through an already existing linear cut in the wall. According to the
videos, shaped charges don’t make big fireballs.
Any good 911 Truther knows about thermite from the operative Steven Jones; the rivers of molten steel, traces of thermite in the debris, blah, blah,
blah…but just in case you’ve been living on Mars for the last decade, here’s a layman’s demonstration of thermate, thermite’s weaker cousin:
Once again I’m struck by how dissimilar the thermite explosion is when compared Naudet clip above. This is not to say that there isn’t any merit
to Jon Cole’s argument that thermite could have been used; I believe something like it would need to have been used to cut the steel prior to the
final destruction, but the available evidence doesn’t support thermite being used to cut the “plane-shaped hole”. The hole was there by the
time the fireball erupted after the initial crash, the flames can be seen outlining the hole at the end of the sequence. According to Jon Cole’s
evidence, a big fireball is not indicative of a thermitic reaction.
These babies are designed to penetrate hardened targets before exploding. There are different types of warheads available, as shown in Lockheed’s
video. “We never forget who we’re working for” is their motto. Creepy:

In some cases, 911 eye witness accounts describe missiles:

To get a sense of scale, I used the WTC blueprints which show that every three columns amounted to 10 feet; meaning a JASSM missile would span almost
Using a close up of the blueprint for a model:
On the right side, at least two missiles were used to create the jet’s “wing”:
Several missiles must have been used, with two for each “wing” and a few right up the middle:
Multiple missiles must have been used, from multiple angles. Below is a shot of the first strike from the Naudet film:
Shaped charges and Thermite cannot account for the plane-shaped hole in the North Tower.
• The video evidence is not consistent with the characteristics of either explosive as neither explosive will produce a big fireball as seen in the
• The charges would likely needed to have been planted outside the aluminum cladding to create a “gash” without also blowing the cladding off
the steel, making stealth far more difficult.
• There was no evidence of the showers of sparks common to a Thermite reaction.
• For enough shaped charges to cut that much steel simultaneously, the resulting report and shockwave from the detonation would have been massive.
This would be much more difficult to explain to errant witnesses.
JASSM Missiles fit the evidence.
• Fireballs are consistent with missile explosions.
• The wing-shaped damage could have been caused by multiple missiles from several angles.
• JASSM missiles are bunker busters by nature and can cut steel columns. It is what they do.
• The damage to the left side of the gash is hard to explain at all unless a missile is considered.
• At speed and from the ground, JASSM missiles can look like jets, especially if they’re painted in the colors of one.
• Some witnesses allegedly claimed they saw or heard missiles.
• With Hollow Towers (pre-demolished and stripped of partitions, fixtures, floors, etc), the missiles would travel straight through to the opposite
sides, which they did.
I say missiles dunnit, but I’ve been wrong before and I’m open for discussion.
I am only focusing on the first strike for brevity, and for the fact that the South Tower may have been executed differently.
