Could this have been anything other than a controlled demolition?

Yes.

Closeup videos very clearly show the columns buckling at the start of collapse.

Building 7 is CONFIRMED for controlled demolition. They said so themselves because they wanted to reduce damage to the other buildings, and they were caught on tape saying to "pull it" just 3 seconds before it fell.

How did they find time to plan out a controlled demolition and lay explosives, while the building was on fire though? Unless it was already done before the building caught fire.

...

It was a controlled demolition.

There I no other way it could collapse at near freefall velocity.

Why wouldn't it collapse at near freefall velocity?

Why would a controlled demolition make it "suddenly" able to fall at freefall velocity?

Because it would be slowed down by the resistance proved by the floors beneath it.

In a controlled demolition the individual floors are detonated sequentially so that the building collapses straight downwards to avoid damage to the surrounding structures. This removes the resistance of the floors beneath it.

if the government or whoever was behind this was keen on causing destruction and the death of thousands of people, why would they give a fuck about the surrounding structures

>Because it would be slowed down by the resistance proved by the floors beneath it.
So controlled demolition makes floors just poof out of existence?

>In a controlled demolition the individual floors are detonated sequentially so that the building collapses straight downwards to avoid damage to the surrounding structures. This removes the resistance of the floors beneath it.
1 - the towers very clearly didn't fall perfectly straight down
2 - you can't just make a 200x200 ft slab of concrete, let alone 110 of them, fly to the side for no reason; of course it fell down straight
3 - there has never been a controlled demolition of a supertall, and probably never of a highrise either

Thats not really an arguement.

Fuck off.

How much would it be slowed down?

>the towers very clearly didn't fall perfectly straight down
>there has never been a controlled demolition of a skyskraper before

Thats probably why it didn't fall straight down.

The real issue is the speed at which it fell. Why did the structural intergrety of the building suddenly disappear?

>Why did the structural intergrety of the building suddenly disappear?
because the lower floors were designed to hold the static load of the floors above, not to hold the floors above as they come crashing down at high speed

But what was the mechanism behind the collapse? We all know the jet fuel steel beams meme. How did they suddenly stop provding support completely, instead of bending and buckling first?

buckling in the exterior columns right as the collapse begins can be seen in some of the higher quality videos

After reading the official report and numerous descriptions of witnesses, it seems plausible. The only strange thing is how both planes could hit the towers that well.

They bent and buckled very quickly. Jet fuel can't melt steel beams, but it can weaken them enormously.

>not 110 stories high
>smaller footprint
>wasn't hit by a plane
not sure what you're trying to prove here

They didn't. There was a massive fire in the buildings for an hour before it collapsed. All you morons do is set up false premises.

The fire was only on a coupe of floors, not the entire building.

You think that's hard to hit?

Read the official report and these links:

With a passenger aircraft flying at 500Km/h? Yes.

you aren't even old enough to remember it, lol
the north tower burned for more than an hour before collapsing, with the whole world watching live on TV

ms flight simulator existed in 2001

>you aren't even old enough to remember it, lol

Well thats just not true at all.

If you think the entire building was ablaze, every single floor, then you need to watch the footage again and possibily buy some glasses.

Hello fellow /pol/ user! Since I already know that you won't leave us alone until we say that it was the "Jews", let me go ahead and say so that you'll stop pestering us with idiotic questions. It was the Jews.

I don't think you realize how large the towers were.
If a pilot can land his plane on a runaway, he can definitely hit those.

Here we go again.
Yes.
"pull it" means pulling the firefighters out of the area.
It didn't collapse at near freefall velocity. If it did, it would take 9.2 seconds.
South Tower: 15 seconds
North Tower: 22 seconds
It didn't collpase at freefall velocity.
Correct, and is why it didn't collapse at freefall velocity, and DID cause damage to the surrounding structures, like WTC7.
>1 - the towers very clearly didn't fall perfectly straight down
Yes, both tilted before falling down.
>2 - you can't just make a 200x200 ft slab of concrete, let alone 110 of them, fly to the side for no reason; of course it fell down straight
Correct, but a lot of it did get launched to the side from the air pressure pushing things out.
>3 - there has never been a controlled demolition of a supertall, and probably never of a highrise either
there has been highrise demolitions
It didn't fall at freefall velocity.
>But what was the mechanism behind the collapse?
Jet fuel ignites fires. Fires weaken floor beams. Floor beams buckle and drag perimeter columns inwards. Perimeter columns all break at once and the whole top portion tilts out of position then crushes the lower floors. This happened in both towers.
>We all know the jet fuel steel beams meme.
Steel loses most of its strength long before melting.
>How did they suddenly stop provding support completely, instead of bending and buckling first?
They did bend and buckle first.

I'm not saying that it's impossible, just a bit strange. Especially the plane which flew into the pentagon.

You're a moron. The right side is the side that failed and initiated the collapse. Notice the buckling and the huge fires. The news interviewed someone in the north tower who told them the core had caved in after the plane hit, so the perimeter columns and the hat truss held the building together until they failed.

On the top left side you can see people in the window. Seconds before the collapse, they retreat from the windows, and in several places smoke is pushed out, implying that the inside failed before the outside did.

>"pull it" means pulling the firefighters out of the area.

No. Owner of the building said in an interview on TV that "pull it" meant detonate the explosives.

I doubt Larry ever said such a thing

Another picture. The buckling is even more noticeable.

No he didn't. He said the phrase "pull it", which is a term firefighters use. He never said he meant blowing it up. "pull it" is not even a term demolition teams use.

Why not post the closeup images?

I'm showing pictures of the north tower. Your gif is of the south tower, which is easier to explain because the plane hit lower, and on the side, so that side was extremely compromised and failed early. And there are several videos showing the buckling. There are no videos showing the north tower's rapid buckling, only a few pictures.

Thanks, didn't realize that you were only talking about the north tower.

These threads are always low-effort bait; why even bother replying?

There are actually a few videos that seem to show the rapid buckling and breaking of the north tower's columns, but the quality is poor and it could just be smoke pushed out of the windows. There are, I think, two videos taken from the east that show the tower tilting to the north.

Some not so fun facts about the towers. If the towers didn't collapse, the 1500 people above the impact floors in the north tower and the 600 people above the impact floors in the south tower would've died anyway. They were stuck in an oven with the exit routes sealed, getting slowly cooked alive and suffocated from the smoke that filled every single room down to the floor. The firefighters likely knew this already, their job was to get the people below the impact zone out and try to find intact exit routes for the people above. In the south tower, there was one intact staircase, but the people above were told to stay put so the firefighters could come up and rescue them. In the north tower, there were no intact exit routes, so they were stuck.

>In the south tower, there was one intact staircase, but the people above were told to stay put so the firefighters could come up and rescue them.

Did this make any difference?

A few people found the staircase and got out, which is why we know there was an intact staircase.

I should also mention the staircase would've been blocked by the fires as they continued to spread, so all 600 people wouldn't have been able to get through that one staircase in time.

Another fun fact:
if the attack had happened an hour later, there would be 5000 or more additional dead
