What?!?!?! How did anyone know that WT7 was going to fall, let alone set up a "prior knowledge" collapse zone? Do you realize what you just typed? This is exactly what my last post was referring to. Absurd levels of willful ignorance or denial.
Fire Chief's Assessments of WTC 7
"A little north of Vesey I said, we’ll go down, let’s see what’s going on. A couple of the other officers and I were going to see what was going on. We were told to go to Greenwich and Vesey and see what’s going on. So we go there and on the north and east side of 7 it didn’t look like there was any damage at all, but then you looked on the south side of 7 there had to be a hole 20 stories tall in the building, with fire on several floors. Debris was falling down on the building and it didn’t look good.
Early on, we saw a bulge in the southwest corner between floors 10 and 13, and we had put a transit on that and we were pretty sure she was going to collapse. You actually could see there was a visible bulge, it ran up about three floors. It came down about 5 o’clock in the afternoon, but by about 2 o’clock in the afternoon we realized this thing was going to collapse.
Firehouse: Chief Nigro said they made a collapse zone and wanted everybody away from number 7— did you have to get all of those people out?
Hayden: Yeah, we had to pull everybody back. It was very difficult. We had to be very forceful in getting the guys out. They didn’t want to come out. There were guys going into areas that I wasn’t even really comfortable with, because of the possibility of secondary collapses. We didn’t know how stable any of this area was. We pulled everybody back probably by 3 or 3:30 in the afternoon.
Chief Daniel Nigro's Report
Release date: September 23, 2007
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.

Demo crews really need to see how much steel and concrete reinforced deconstruction they can do with a couple of large hollow aluminum projectiles and some outwardly burning jet fuel. Likewise, if they would just study building 7 they would just need a couple of Bic lighters to bring down 47 stories of modern engineering. They are wasting a lot of money with explosives timers and det cord.
No. Just stop. No fire had previously taken down a steel framed building...
Kader Toy Factory Fire
At about 4pm on May 10th, 1993, a small fire was discovered on the first floor of part of the E-shaped building. Workers were instructed to keep working as the fire was thought to be minor. The fire alarm in this building did not sound.
The building was reinforced with un-insulated steel girders which quickly weakened and collapsed. This part of the building was dedicated to the storage of finished products and the fire spread quickly. Other parts of the factory were full of raw materials which also burnt very fast... Fire-fighters arrived at the factory at about 4:40pm, to find Building One about to collapse.
The Kader buildings,...collapsed relatively early in the fire because their structural steel supports lacked the fireproofing that would have allowed them to maintain their strength when exposed to high temperatures.
A post-fire review of the debris at the Kader site showed no indication that any of the steel members had been fireproofed.
There is audio of fire fighters calling for the logistics needed to put out the fire in 1 and 2 before they collapsed and yet they just gave up on a couple office fires???
Indications of the Imminent Collapse of the World Trade Center Buildings Disprove Explosives Theory
Exterior columns buckled because the fires weakened the floor trusses and the floors sagged. The sagging floors pulled on intact column connections so as the floors sagged down, they pulled the exterior columns inward. This inward bowing of the exterior columns was evident to observers such as the police helicopters circling the towers.
"The NYPD aviation unit reported critical information about the impending collapse of the buildings." They could see that the exterior steel beams of the buildings were bowing. You can see the inward bowing of the steel columns in pictures of both WTC 2, (the first building to collapse) and WTC 1 (the second building to collapse.)
Dr. Shyam Sunder, lead investigator for NIST's building and fire safety investigation into the WTC disaster, said, "While the buildings were able to withstand the initial impact of the aircraft, the resulting fires that spread through the towers weakened support columns and floors that had fireproofing dislodged by the impacts. This eventually led to collapse as the perimeter columns were pulled inward by the sagging floors and buckled." "The reason the towers collapsed is because the fireproofing was dislodged," according to Sunder.
If the fireproofing had remained in place, Sunder said, the fires would have burned out and moved on without weakening key elements to the point of structural collapse."
Don't give me the "so much loss already, why risk it?.... I mean pull it?

Steel beams can collapse under little more than their own weight in a structure fire. Even structure fires that don't involve large amounts of high btu value liquid hydrocarbon fuels.

The Bressmer Co. Building fire 1948.
It's so obvious. You people who defend the official narrative have your head's in the sand.
I remember the day of 9/11. I didn't watch much TV then and I answered the door, a friend came in and said do you know we've been attacked? I turned on the "bunny ear" television and got a grainy image on my local channel 11. I was absolutely shocked like everyone else. But what didn't add up was when I left for a minute and came back the media was saying both towers fell but weren't showing footage. I was getting ready to witness two buildings broke off at the top and smoking, I thought. The whole buildings disappeared though. There is no way the small sections on top destroyed the other 80 floors. Pancake/weakened truss theory people can get lost. What happened to the concrete core?
Actually he makes an argument for the building toppling over where the fires burned, bending over, not telescoping into itself, also I would like to know how long did that piece of steel sit in the forge to get that soft.
Remember that lady standing in the wreckage if it was that hot where the building was hit she would be dead not from the airplane strike but from the heat alone. The fuel burned off in the explosion anyways.
So how hot are office fires with regular typical building stuff again ?
