That video does not depict the sound of a demolition explosion. That sound is indicative of structural failure. Case in point in this video where a crane breaks up at time line 0:42. What do you hear?





Damn! You don't have the slightest feeling for Mechanical Physics, and you really show it.

That is a PULLING vector enforced on that huge steel pin.!
By a too heavy live load hanging at a crazy long "arm".

Please be so kind to show me such mechanism at the INITIATION of the WTC collapses.
Not after that point in time, we all saw the tops first buckle, then hinge to one side, that was not the INITIATION moment. When it hinged, then of course some columns at the other side of the hinge were stretched and their bolds and welds broke far before the column itself could SNAP. They did not snap, their connection instruments broke. The welds and bolts.
That's why NIST saved only two CORE columns from one tower, and one CORE column for the other tower, but not from the collapse INITIATION points, but from some lower impact regions. Ask Major Tom...
And that's why as good as all visible columns in the total debris field were perfectly STRAIGHT, since their failure points were at welds and bolts.
As I told you before, I am not interested in the collapse mechanism, we must concentrate on the very start of the collapses. The INITIATION moments and their mechanics.

C. Faster than free fall acceleration.

The correct answer to this question is C. The reason for this is called Momentum Transfer.

The inside of WTC 7 started falling 6 seconds before the exterior. It gained momentum during this time. A portion of that momentum was transferred to the exterior of the building. This explains the 2.4 seconds which actually exceeded Freefall.

There are 2.25 seconds of long moments of instantaneous free fall found in the collapse of WTC-7, first by David Chandler, then admitted by NIST.
That is an ETERNITY in Newtonian physics. The whole top of WTC-7, the 47th floor down to the 13th floor, went during a PERIOD of 2.25 seconds at FREE FALL ACCELERATION SPEED through the 34 meter high space first occupied by its 13th to 7th floor, with no measurable resistance at all.
Only when it met the still firmly erect 7th and lower floors, it DECELERATED BELOW FREE FALL SPEED.


Remember, I had asked you to post the time lines where explosions can be heard in that video. Tell, us, why were no demolition explosions seen nor heard as WTC 7 collapsed?

We can take a look at this message as well.



E-mail from Chief Daniel Nigro

Regarding WTC 7: The long-awaited US Government NIST (National Institute of Standards and Technology) report on the collapse of WTC 7 is due to be published at the end of this year (although it has been delayed already a few times [ adding fuel to the conspiracy theorists fires!]). That report should explain the cause and mechanics of the collapse in great detail. Early on the afternoon of September 11th 2001, following the collapse of WTC 1 & 2, I feared a collapse of WTC 7 (as did many on my staff).

The reasons are as follows:

1 - Although prior to that day high-rise structures had never collapsed, The collapse of WTC 1 & 2 showed that certain high-rise structures subjected to damage from impact and from fire will collapse.

2. The collapse of WTC 1 damaged portions of the lower floors of WTC 7.

3. WTC 7, we knew, was built on a small number of large columns providing an open Atrium on the lower levels.

4. numerous fires on many floors of WTC 7 burned without sufficient water supply to attack them.

For these reasons I made the decision (without consulting the owner, the mayor or anyone else - as ranking fire officer, that decision was my responsibility) to clear a collapse zone surrounding the building and to stop all activity within that zone. Approximately three hours after that order was given, WTC 7 collapsed.

Conspiracy theories abound and I believe firmly that all of them are without merit.

Nothing in his report even remotely suggest the use of demolition explosives or thermite. Since debris in this photo is falling at free fall speed while outpacing the collapse, how does that translate into a free fall collapse?

Fact of the matter is, if dust plumes and debris are outpacing the collapse of the building, as shown in the following photo, then common sense logic says the building is not falling at free fall speed. In other words, dust plumes and debris have reached the ground while the collapse is still ongoing many floors above the ground. How conspiracy theorist continue to overlook those facts is simply amazing.

Not Falling at Free Fall Speed



Note to self : Never go sky-diving or base jumping with skyeagle409. Better don't get in the same plane either.


I don't do base jumping and there have been those who have learn for the very last time why it is dangerous.

""Then where are the resulting ROWS of OTHER JUST as LOUD HUGE explosion sounds we should be hearing then thereafter? ""

Please point out the time lines in this video where demolition explosions can be heard.



From the comments section :

thatch : This video is incomplete. It is missing 8 seconds of footage that is crucial to understanding why the building fell as it did. I implore everyone watching this to do another search for WTC7 collapse, but this time including the terms "rooftop penthouse". You will see the East penthouse collapse long before the shell of the building comes down. This is the smoking gun truster's don't want you to see.


I changed two letters, CAN YOU FIND THEM?
Could you now stop posting this juvenile video? Because repeatedly asking that question discredits your reputation here with every new post.

Your rope example is flawed for the WTC cases. Those floors did not fall freely as separate entities in air. They had to fall through a LOT of steel components, resisting their fall, in case of a true NATURAL collapse.
It's a whole different playground, when we introduce well placed explosives in an UNNATURAL collapse.

And you forgot one crucial thing :
wecomeinpeace : ""What clinches it for me is that the WTC7 pre-collapse seismic signal was larger in peak energy than the collapse of the entire building, so it simply cannot be explained away by a partial collapse inside the building.""

See my opening post its seismic diagram. There is that huge pre-collapse seismic signal, much more energetic than the rest of the amplitudes in that seismogram. At 1/3 of those 8.5 secs where the biggest amplitudes were registered, those 9 cutter charges audible in the Ashley Banfield interview, started exploding.


2) Increase of rocking 6 seconds before visible collapse.
About 6 seconds before the collapse first becomes visible the northwest corner starts to rock more intensely. This movement was detected by the NIST and they consider it to be the earliest detectable motion. The first visible movement was the collapse of the east penthouse and is indicated in the graph. Once the east penthouse begins to fall, the rocking becomes much more intense until the whole core starts to fall collectively about 4 seconds later.



And the 2 top inside portions, and the East and West penthouses above them, sunk during 8.5 seconds, and not 6 seconds, according to NIST's earlier reports. Those NIST time lines from the first visual east penthouse denting to global collapse start, I posted as screen shots. See them in my 5 signature-links
There were according to femr2 (see Major Tom's site) only about 0.8 secs of exceeded free fall acceleration, and the total free fall period was 2.25 secs said NIST while femr2 found 2.4 secs.

There are no demolition explosions in those videos. I asked specifically for the time lines where demolition explosions can be heard and you provided me with nothing. Now, let's take a look at what real demolition explosions sound like.



Now, to let you in on a little secret. Demolition experts who were near WTC 7 when it collapse, have stated that heard no demolition explosions. One of those companies, was protec, the company that was operating seismic monitors at the time. The demolition experts have also stated that their seismic monitors did not detect demolition explosions. I contacted that same company last year to gather certain information. Now, for some real information.

How Building Implosions Work

The first step in preparation, which often begins before the blasters have actually surveyed the site, is to clear any debris out of the building. Next, construction crews, or, more accurately, destruction crews, begin taking out non-load-bearing walls within the building. This makes for a cleaner break at each floor: If these walls were left intact, they would stiffen the building, hindering its collapse.

Destruction crews may also weaken the supporting columns with sledge hammers or steel-cutters, so that they give way more easily. Next, blasters can start loading the columns with explosives.

Demolishing steel columns

Demolishing steel columns is a bit more difficult, as the dense material is much stronger. For buildings with a steel support structure, blasters typically use the specialized explosive material cyclotrimethylenetrinitramine, called RDX for short. RDX-based explosive compounds expand at a very high rate of speed, up to 27,000 feet per second (8,230 meters per second). Instead of disintegrating the entire column, the concentrated, high-velocity pressure slices right through the steel, splitting it in half. Additionally, blasters may ignite dynamite on one side of the column to push it over in a particular direction.

How many times have I stated that steel frame buildings must to be pre-weakened, which is a very noisy and dirty operation that generates tons of waste material? How many times have I stated that elevators shafts and stairwells must be cut and firewalls remove before demolition explosives are firmly placed on steel columns. In such cases, there was no way that such an operation could have been carried out in crowded, occupied buildings and not generate many complaints

Since the impacts were violent enough to dislodge fire protection from the steel columns, there was no way that explosives would have remained firmly attached to steel columns either, which would have rendered explosives ineffective.

You can't place explosives in steel frame buildings and expect the building to collapse. That is Hollywood wishful thinking that you see only in the movies and these photos are an example of what happens when a building is not properly pre-weakened.

Photo #1

Photo #2

Photo #3

I sat here and watched as CT folks posted seismic data that at no time, indicated demolition explosions at ground zero. Simply amazing!!

Now, you know the rest of the story, and think again why a huge bomb failed to bring down WTC 1 in 1993, which left its steel structures standing within that huge bomb crater.

At 1/3 of those 8.5 secs where the biggest amplitudes were registered, those 9 cutter charges audible in the Ashley Banfield interview, started exploding.


Demolition experts, some who were near WTC 7 when it collapsed, have stated for the record that at no time did they hear demolition explosions at ground zero, which is clearly backed by the lack of explosions as WTC 1, WTC 2, and WTC 7 collapse, and there were no explosions as WTC 5 suffered an internal collapse due to fire only.



The Collapse of WTC 7

At approximately 2:00 pm, firefighters noticed a bulge in the southwest corner of 7 World Trade Center between the 10th and 13th floors, a sign that the building was unstable and might cave to one side or "collapse".

During the afternoon, firefighters also heard creaking sounds coming from the building and issued uncertain reports about damage in the basement.

Around 3:30 pm FDNY Chief Daniel A. Nigro decided to halt rescue operations, surface removal, and searches along the surface of the debris near 7 World Trade Center and evacuate the area due to concerns for the safety of personnel. At 5:20:33 pm EDT on September 11, 2001, 7 World Trade Center started to collapse, with the crumble of the east mechanical penthouse, while at 5:21:10 pm EDT the entire building collapsed completely.

There were no casualties associated with the collapse.

Now, let's here the rest of the story.

Collapse of the World Trade Center

Immediately following the attacks, a building performance study (BPS) team of engineering specialists was formed by the Structural Engineering Institute of the American Society of Civil Engineers (SEI/ASCE) and Federal Emergency Management Agency (FEMA). The BPS team issued its report in May 2002, finding that the aircraft impacts caused "extensive structural damage, including localized collapse" and that the resulting fires "further weakened the steel-framed structures, eventually leading to total collapse." They also presented recommendations for more detailed engineering studies of the disaster.

The BPS team investigation was later followed by a more detailed investigation conducted by the National Institute of Standards and Technology (NIST), which also consulted outside engineering entities. This investigation was completed in September 2005.

The NIST investigators did not find anything substandard in the design of the WTC towers, noting that the severity of the attacks and the magnitude of the destruction was beyond anything experienced in U.S. cities in the past. They also emphasized the role of the fires and found that sagging floors pulled inward on the perimeter columns: "This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers."

In the immediate aftermath of the attacks, numerous structural engineers and experts spoke to the media, describing what they thought caused the towers to collapse. Hassan Astaneh, a structural engineering professor at the University of California at Berkeley, explained that the high temperatures in the fires weakened the steel beams and columns, causing them to become "soft and mushy", and eventually they were unable to support the structure above.

Astaneh also suggested that the fireproofing became dislodged during the initial aircraft impacts. He also explained that, once the initial structural failure occurred, progressive collapse of the entire structure was inevitable.

Cesar Pelli, who designed the Petronas Towers in Malaysia and the World Financial Center in New York, remarked, "no building is prepared for this kind of stress."

#We can go on like this forever...

Arguments and counter arguments.


As far as free fall, demolition explosions, thermite, and Molten steel are concerrned, they can be effectively ruled out because after 14 years, there is still no evidence to support those claims.


O.k. let me try and explain something to you. I want you to go along with it o.k.? and be 100% truthful regardless of where it leads... it may seem as though this is off topic but when it comes to an end I assure you there is a point to this.

I want you to think of an animal. Draw it on a piece of paper and put it where you can see it. then I want you to tell me when it's done.. do not tell me what the animal is.

Not true. NIST invented those "sagging trusses" in 2005, and later came back on their interpretation of those sagging aluminium ceiling rims in front of a row of windows, which was their ONLY "evidence" which they interpreted as sagging floor slabs.
I indicated to them, that they should pay attention to their own publicized floor plans, which made it crystal clear that the floor slabs at those positions were laid out PERPENDICULAR to the perimeter wall. NOT PARALLEL !

Thus, WHAT really caused that line of about 80 cm inward bowed perimeter Vierendeel column packs, which were perpendicularly attached in a "stepping stone" manner to the huge area of composite floors?
Only dislodged first rows of core columns attached to the inner sides of those huge composite floor areas can explain that. Those core columns slipped downwards after being cut by preliminary installed cutter charges, pulling those huge floor areas with them downwards under a small but significant angle. Enough to pull those exterior columns inwards.
That system hung in an uncertain balance for a few minutes, until the initiation charges were set off. And then the inevitable ROOSD floor collapsing started, assisted by some other charges placed at the MER double floors, where those Vierendeel column packs were welded instead of bolted together.
And some cutters probably had already, or were in the process of dislodging the lowest core columns when those spires after a few seconds standing time, at last surrendered and sunk vertically down, after we saw the longest ones swaying quit a lot.


""Astaneh also suggested that the fireproofing became dislodged during the initial aircraft impacts. He also explained that, once the initial structural failure occurred, progressive collapse of the entire structure was inevitable.""

Exactly ! Inevitable !
Only, my dear Watson we have a huge problem at hand. The fireproofing at the initiation floors were firmly attached, since only a very small tip of a wing had damaged that floor at a far left and for the other tower at the far right position on the perimeters.
And the fires had only just reached both Tower's collapse initiation floors, while the fully intact fireproofing there was good for 2 hrs of keeping the structural steel cooler than 150, maximal 300 degrees C.

Only when it met the still firmly erect 7th and lower floors, it DECELERATED BELOW FREE FALL SPEED.


Remember, I had asked you to post the time lines where explosions can be heard in that video. Tell, us, why were no demolition explosions seen nor heard as WTC 7 collapsed?

BECAUSE YOU POST TOO SHORT VIDEOS TO EVER HEAR IT.... see my above posts.

We can take a look at this message as well.



E-mail from Chief Daniel Nigro

Regarding WTC 7: The long-awaited US Government NIST (National Institute of Standards and Technology) report on the collapse of WTC 7 is due to be published at the end of this year (although it has been delayed already a few times [ adding fuel to the conspiracy theorists fires!]). That report should explain the cause and mechanics of the collapse in great detail. Early on the afternoon of September 11th 2001, following the collapse of WTC 1 & 2, I feared a collapse of WTC 7 (as did many on my staff).

The reasons are as follows:

1 - Although prior to that day high-rise structures had never collapsed, The collapse of WTC 1 & 2 showed that certain high-rise structures subjected to damage from impact and from fire will collapse.
LT : No, it proves that when you believe hard enough what they tell you to believe, to keep your pension money, or to stay upright by pure patriotism, you will follow any line of official reasoning. He's retired now.

2. The collapse of WTC 1 damaged portions of the lower floors of WTC 7.
LT : there's only the clear reasonable small damage to the southeast WTC-7 corner over just a few floors heights, and not deeper than the office walls inside there, as can be seen in the much clearer photos, FOIA freed from the NYPD chopper units full photographic evidences.
The single photo NIST used for many years to again muddy the waters (since they had ALL photos from that chopper at hand all that time), was the only one where a gust of smoke rising along that corner damage, made it look as if it was much higher and deeper. The posting of all chopper photos made it crystal clear how small that damage really was.
And that's why I question all of Chief Nigro's remarks about that day, he should have known that fact, by his own eyes or by solid reports.


3. WTC 7, we knew, was built on a small number of large columns providing an open Atrium on the lower levels.
How many, how strong, what steel quality, etc. It turned out that the lower structural steel in the 12 lowest floors or so, were strongly over-engineered, to protect at all costs the huge CON-ED power station under the 7th and 5th floor, that provided "juice" for the WHOLE WTC project. BsBray11 in 2005 posted a few photos of that horizontal and vertical structural steel while it was erected. It was really impressively THICK.

4. numerous fires on many floors of WTC 7 burned without sufficient water supply to attack them.
LT : Strange that Nigro decided to stop wasting water at those few fires at lower floors that were the only ones reported and photographed after the North Tower collapse. There was water available from the Hudson where the fire boats were mored. And there were pumper trucks that could have delivered the necessary water pressure to put out those few fires after 10:30 a.m. Another reason why I mistrust Chief Nigro's decisions. While you see those fire boat lines aimed at those totally engulfed in huge flames WTC 5 and 6 buildings, which even for the casual observer looked totally unrecoverable. One line would have been sufficient to keep the south facade of WTC-7 wet, to stop flames from WTC-5 and WTC-6 jump over and starting new fires at the bottom floors of WTC-7. The rest of the fire boat lines could have been coupled to those pumper trucks their lines and rolled out inside WTC-7.
It's also very strange that the riser pipes in WTC-7 were damage beyond repair, since no real reports are available about any form of investigation into the specific cause of that water and sprinkler system failure. There were huge water tanks in all three towers, but CON-ED had switched of all normal power in the whole WTC complex, they said, at just before 10 o'clock. So also to the water pumps for the riser-pipes.


For these reasons I made the decision (without consulting the owner, the mayor or anyone else - as ranking fire officer, that decision was my responsibility) to clear a collapse zone surrounding the building and to stop all activity within that zone. Approximately three hours after that order was given, WTC 7 collapsed.

Conspiracy theories abound and I believe firmly that all of them are without merit.

Nothing in his report even remotely suggest the use of demolition explosives or thermite. Since debris in this photo is falling at free fall speed while out pacing the collapse, how does that translate into a free fall collapse?

DO NOT POST PHOTOS OF THE TWINS, WHEN DISCUSSING WTC-7.!
That's severely muddying the waters. It's not intelligent debate.

And for your info, I posted that snippet that was immediately taken over by all debunkers at JREF etc at my time of posting.
My remark that the BBC camera man running away from the South Tower collapse had his camera still on, and filmed unknowingly the first huge chunk of Vierendeel exterior panels that impacted the ground very near to the base of that Tower, while clearly to see, at least half of that Tower was still erect. Thus the collapse times for both Towers were about 10 seconds longer than a truly resistance-free gravitational free fall collapse would have cost (+/- 6 to 8 seconds)
So yes, there was resistance, but less than would be expected by engineering principles.

Fact of the matter is, if dust plumes and debris are out-pacing the collapse of the building, as shown in the following photo, then common sense logic says the building is not falling at free fall speed. In other words, dust plumes and debris have reached the ground while the collapse is still ongoing many floors above the ground. How conspiracy theorist continue to overlook those facts is simply amazing.

WHAT'S REALLY AMAZING IS YOUR LAG_BEHIND ON LONG SINCE 2005 ESTABLISHED SIMPLE FACTS.
So stop coloring Truthers, Doubters, whatever, as imbeciles. You should really stop that insinuating behavior.
It paints you as a person relying on twitching well known facts, so you can establish a cloud of doubt in fresh readers minds. One thing is very clear in the former 33 pages, they don't trust your argumentation techniques.

That is a good video find, indeed a bit more south and nearer to WTC-7, and definitely an omnidirectional microphone in the hand of the reporter.
And I also don't hear anything that sounds like the other video its deep sound in it, in fact I hear nothing that could be assigned to the collapse, which is already an indication that that microphone could not pick up any collapse sounds at all. The woman did, or did she react on the bystanders that looked in the right direction? To me it's like she is reacting on some rumble or so, since she turns around, frightened looking. But we hear with our ears nothing indicative at all related to what we see coming down.
Perhaps an audio expert could filter something out? Please include video-times in an audiogram from it, so we can calculate distances for sound travelled via Google Earth or Maps..

Microphone pickup Patterns :



What are Omnidirectional Microphones?

Potential Disadvantages

Ideally, an omnidirectional mic would pick up sound in a perfect circle around its center. The laws of physics make this somewhat challenging, however, and in real-world use, this type of microphone cannot pick up sound perfectly from every direction. It can also cut out some high and low frequencies, and sound coming from an extreme angle may not be reliably detected.


That said, we have one unsolvable problem at hand. We don't know what type of microphone was attached to the camera, or held by hand by the filmer of the Judicial Watch video.
It sounds and looks as if that camera was on a tripod, and had a directional type of microphone attached to the camera housing. Since it seemed to have been a static shot from quite some distance, we may expect that if the camera man was a pro, he would have chosen for a directional microphone, like the ones shown in my above video.

One thing we are told by Charles Ewing Smith, there were TWO identical videos handed over by NIST to the court, this one with that deep sound in it, and the duplicate with no deep sound in it.
Why did someone at NIST handed over either a doctored video where that deep sound was inserted in the original audio file, or a doctored video where that deep sound was taken out from the original audio file.?

Perhaps "my assistant" who constantly keeps me sharp, waypastvne, can find the description of the camera that was used, in this TV news repository that saves such descriptions for all their footage? He also took the trouble and found this video he posted. Good detective work.

Someone could find it in this HUGE TV-news video depository at archive.org , or you can find a more complete version of this collection (3000 hours of television from 20 channels over 7 days) at Understanding 9/11: A Television News Archive : www.archive.org...

First, he claims the building was 100 meters wide, and used that to "calibrate the scale" in his video analysis. 100 meters, really?

Then he uses the "vertical spacing" of the horizontal lines of a heavily compressed multi-generational YouTube video to find the 29th floor. No expert in video analysis would even both with such a poor resolution video -- especially at a non-even scale of 2.001085 which will introduce inaccuracies.

So, he's starting with very bad data as the baseline for his calculations. It can't be trusted.

He's placing marks, frame-by-frame, for the corner of the building as it falls... coming to the conclusion that the acceleration of the building is indistinguishable from free-fall -- that is, if you rely on bad math, with bad assumptions, using a horrible source video.


That was David Chandler's earlier video on the subject. After his confrontation with NIST on their comments meeting, he made a new one based on a HD version he probably found in that News Archive I just posted.

By the way, NIST only came a tiny bit closer to free fall speed acceleration values during those 2.25 secs, when they repeated the same technique with their top notch software....

So your words are much too harsh regarding David's methods.

In this LINK from my signature, you will find a few more of Davids calculations.
Only later came a new technique with partial pixel measurements, which delivered even better finesse.
Look for that in this page by Major Tom its lower regions for a few of them, here is one from Savitzky-Golay posted by femr2 there :

LT : If you are so sure about that, then this FOIA freed video by Charles Ewing Smith with that huge explosion sound in it, must for sure make you severely doubt your own words after seriously contemplating my explanation following that video.


S.O. : No. I've seen the video, several times. Since when does it take one explosion to bring down such a large building?

To me, the sound is consistent with catastrophic failure of support steel under extreme stress.
===================

SkepticOverlord, there is ONE (1) deep explosion sound, and NINE (9) audible explosion sounds found in two videos known for the collapse of WTC-7. There were probably more, not recorded because of the 4 to 6 blocks cordoning off of the WTC-7 area, all done in the 3 hrs after Chief Nigro ordered the pull out of all people from the WTC-7 area on 14:30 p.m.

The real sound in nearly all 9/11 TV News is for 99 % filtered out by those Army Editors assigned to all major networks their Editing Rooms in the weeks before 9/11. Reason given? To help the networks with the 9 or so war games planned and executed on and around 9/11/2001.
Here are the real explosive sounds, from FOIA freed videos, ripped from the claws of NIST :

That deep explosion sound is the only clearly audible explosive artifact in this WTC 7 collapse video :

Title : WTC 7 Explosion - NIST FOIA Cbs-Net Dub5 09
That's a non-You Tube reserve copy of the famous video of the deep explosive sound just 2 to 4 seconds before the east penthouse on the roof of WTC 7 started to sink.

This is the audio print-out of the deep explosion sound and the rest of the WTC-7 collapse sound signals in this FOIA freed video :

The most important video for both South and North tower collapses, "9/11 WTC Detonations Finally Revealed" from -BoneZ- (Matt H. posting quality research at Major Tom's site) did not get much attention here. Because at last you can hear clearly the first detonations that forced that top-part of WTC North to collapse in on itself, downwards. And pulverized a great deal of that top-part already.

Time to listen also to that convincing man again, in the same video, about all the explosion sounds he personally heard near Ground Zero, that were however already taken out from ALL the main networks their footage before it got spread and aired, which amazed him to no end when he came home and watched the endless repetitions, WITHOUT THOSE identical rows of EXPLOSION SOUNDS he just witnessed at both towers :

This is one of the witnesses who was really amazed when he discovered that HUGE cut and paste job done in those Editing Rooms. And is one of the indications for this massive editing out of all those explosion sounds. They seemed to have missed only a few faint ones in the hurry and tremendous pressure of that frantic day.

Not harsh enough actually. The all-too-common failure of "9/11 Truth" people -- relying on really poor quality videos as a basis for the claims. You simply can't use the horizontal pixelization of a really bad YouTube video to pick out floors in a building.
