I have reservations about NIST's report's on all those three towers, but to be sure, all those collapses involved asymmetry.
That is not to say that what the NIST'S report say's is a given...they had to review WTC7's report to accomodate the freefall aspect, and for the twin towers, failed to explain the molten metal, firemen and others, talked about incessantly.
In essence, those things are still in the air, why should they be? the vacuum leaves all kinds of speculation, NIST took their money and ran, apart from the WTC7 review, while the scrap metal from the twin towers, mostly disappeared...as if by magic on a slow boat to China.
Many questions!

It was the #ing BBC in the UK, not some local news station:


No the BBC got it from Reuters, who in turn picked it up from local NY station …….

The report was that the FDNY was anticipating WTC 7 might collapse . They began clearing the area around WTC 7
at around 3 pm . In fact I was in my firehouse in NJ listening to radio transmissions from the WTC ( neighboring city who had sent the entire day shift to scene - we were covering their city)

In being passed from organization to another get garbled

Sure

I know people wo worked in that building It was cleared before 930

The collapse of the towers had damaged the water mains in the area, cutting off water supplies to the building sprinklers and standpipes

The FDNY made a run at saving WTC 7 - reports from the crews searching the building reported heavy damage
from impacts of debris from WTC 1

Most important was that the standpipes had no water No fire chief is going to put his men in a damaged building
(no elevators have to hoof it) No water to fight fires . Again no fire chief will put his men in such a situation

To easy to get cut off Shortly after noon Incident command ordered all personnel out of the building

Collapse unit from Rescue 3 had arrived on scene , a transit was set and locked on one corner of the building
BY 230 spotted a 3 story bulge in the SW corner and transit showed building shifting out of plumb

It was this that caused the incident command to order collapse zone around WTC 7 and all personnel cleared from area

I know this because 6 months after 911 attended a seminar featuring the incident command officers of the FDNY who
explained in detail what was done that day

Who the **** would you like it to be sponsored by? What source would do it neutral for you? Take a look at the results and Revisit.


Getting A&E for 9/11 to sponsor a report into wtc7 is like getting Lamborghini to sponsor a report into the words best sports car.....it’s gonna be more than just a little bias. Even more so if they’re paying over $300k for it.

Cool, I see your point there

But a Pilot knows better, after all the evidence ....that mixing ring on the engine on the street.....epic fail.....

It sure was cool how 12 minutes after the two towers fell a lineup.....a roster of batters was placed in batting order to speel expertness explaining

Why did they know they would a bunch of sidewalk experts explaining for tv......

One after the other adressing the different aspects

The cleanup batter....number 4 spot......the best lookin one.....

Home run....cleared the bases

Turn our hats backwards....it's RALLY TIME

The smoke rising from Shanksville.....a barbeque .......the witness at the hilltop when the drone went over.....

The first helicopter crew there.....not enough debris to fill a suitcase

ABC reporter at the Pentagon....

You guys know the Pentagon......no scrape marks on the edge of the slab at the column line on the exterior.
No marks in my pic of the scene looking from the inside out......after it was cleared. No concrete repair needed at the entry on the perimeter strip of the slab foundation...

Hey, boys....shoulda been damage at the perimeter strip.......

Again the issue of the reporter saying it had collapsed when it was in the background has been explained. Essentially it happened after a local news station picked up communication from the FDNY saying that WTC7 was about to collapse, this was picked up by the BBC who then incorrectly said it had collapsed. I don't know about you but I am old enough to remember the confusion of that day so its really kind of surprising more of this didn't happen. Its like at the time of the Boston Bombings a few years back I clearly recall hearing a report about another bomb that had gone off only for it to be retracted 5 minutes later.

Most 9/11 conspiracies have these kind of simple explanations.

What I personally find really interesting is how many "Truthers" will ignore the very serious questions that have to be asked about the Saudi cover up. But I guess thats a chat for another time....

Do all the others workers have the same name as the person talking? As you in that you replied to yourself?

Structures guy then?

From another thread.. for the twin towers

The vertical beams in one of the bottom corners got missed for some reason. I don't know why. Did not take long for it to fall apart with all the other damage going on.

for Richard Gages statements, what happened to the rest of the building? Looks true to me.

Sorry. Evidence shows the core fell from loss of lateral support after the floor system failed.


The whole truth movement is based on created mythology, not the actual photographic, audio, video, seismic evidence, physical evidence.

Again...

After the Hulsey report failure, AE is no dumbing down their campaign.

Good video on Mick West explaining why the truth movement is full of crap.

At about the 10 minute mark, it is explained the collapse of the twin towers was not through the cores with video evidence. The floors were torn from around the tube in tube design.




The Dumbing Down of Architects and Engineers for 9/11 Truth

Again supported by the actual physical evidence

Except when the upper potion of the building above the Jet impact fell into the building below it broke floor connections. The core failing fist does not explain proven floor connections failures.



Failure of Welded Floor Truss Connections from the Exterior Wall during Collapse of the World Trade Center Towers

app.aws.org...

Analysis of the connections supporting the composite floor system of the WTC towers showed that at and below the im- pact floors, the greater majority (above 90%) of the floor truss connections were either bent downward or completely re- moved from the exterior column. This was probably related to the overloading of the floors below the impact region after col- lapse initiation. Depending upon weld joint geometry, detachment of the main load-bearing seats was a result of either fracture in the heat affected zone of the base material (standoff plate detached from spandrel) or through the weld metal (seat angle detached from standoff plate). Failure in both cases was assumed to be a result of a shear mechanism as a result of overloading from floors above impacting those below. There did not appear to be a significant change in distribution of failure modes of the floor truss connections when comparing those connections inside vs. outside of the impact region or those ex- posed to pre-collapse fires and those that were not.



The below is supported by the video, audio, seismic evidence.




The destruction of the Twin Towers has been called "the most infamous paradigm" of progressive collapse.[6] They began with the local failure of a few structural components and progressed to encompass the whole of the structure.[22] Such collapses are characterized by "the separation of structural components (including non-load bearing elements), the release of gravitational energy, and the occurrence of impact forces." The vertical impact force supplies the propagating action, the principal forces are parallel, and the primary load transfer is serial.[23] The key element in the structure that failed was constituted by the combined "vertical load-bearing members of one entire storey." Excepting the top floors of the building, which would not have released sufficient gravitational energy to bring about a total collapse, the collapses could have begun with the failure of any story.[24]

Under these conditions, the towers collapsed symmetrically and more or less straight down, though there was some tilting of the tops of the towers and a significant amount of fallout to the sides. In both cases, the section of the building that had been damaged by the airplanes failed, which allowed the floors above the impact zone to fall onto the undamaged structure below. As the collapse progressed, dust and debris could be seen shooting out of the windows several floors below the advancing destruction, caused by the sudden rush of air from the upper levels.

During each collapse, large portions of the perimeter columns and possibly the cores were left without any lateral support, causing them to fall laterally towards the outside, pushed by the increasing pile of rubble. The result was that the walls peeled off and separated away from the buildings by a large distance (about 500 feet in some cases), hitting other neighboring buildings, and starting fires that would later lead to the collapse of Building 7. Some connections broke as the bolts snapped, leaving many panels randomly scattered.[25] The first fragments of the outer walls of the collapsed North Tower struck the ground 11 seconds after the collapse started, and parts of the South Tower after 9 seconds. The lower portions of both buildings' cores (60 stories of WTC 1 and 40 stories of WTC 2) remained standing for up to 25 seconds after the start of the initial collapse before they too collapsed.[13]

Collapse initiation

After the planes struck the buildings, but before the buildings collapsed, the cores of both towers consisted of three distinct sections. Above and below the impact floors, the cores consisted of what were essentially two rigid boxes; the steel in these sections was undamaged and had undergone no significant heating. The section between them, however, had sustained significant damage and, though they were not hot enough to melt it, the fires were weakening the structural steel.

As a result, the core columns were slowly being crushed, sustaining plastic and creep deformation from the weight of floors above. As the top section tried to move downward, however, the hat truss redistributed the load to the perimeter columns. Meanwhile, the perimeter columns and floors were also being weakened by the heat of the fires, and as the floors began to sag they pulled the exterior walls inwards. "The ensuing loss in vertical load-carrying capacity was confined to a few storeys but extended over the entire cross section of each tower."[26] In the case of 2 WTC, the eastern face finally buckled, transferring its loads back to the failing core through the hat truss and initiating the collapse. Later, the south wall of 1 WTC buckled in the same way, and with similar consequences.[27]

One thing I find troubling is people who won't accept the eyewitness accounts and think wild theories are more credible.

I believe we got most of the story.

Haha they had students and engineers from unrelated fields like marine engineers among there 3000ish members


They had Interior Designers, Artists, Secretaries, Drafters and Interns as members.

The only thing about 9/11 I still do not believe is I think we shot down 93.



That is actually one of the easiest to disprove. All the responding F-16's had was ammo for their 20 mm cannon. If they would have shot down Flight 93, several things would have happened.

One, there would have been an expenditure of 20 mm cannon rounds, leaving a paper trail, accounting for the use of the ammo.

Two, the cannon would have to have been serviced, leaving another paper trail.

Three, the airframe around the gun port would have to have been cleaned and possibly repainted, leaving, yet again, another paper trail.

Fourth, there would be gun camera footage, leaving another trail.

Last you have the pilots. I just finished reading a story where the pilots had discussed ramming Flight 93 if necessary. Why ram, when you could have shot it down.
