London fire vs. 9-11 fire

[Russell]

is this for real?

3. The twin towers collapsed because of the impact and high temperature fire.
When the core gave way the entire building collapsed like a deck of cards. The weight of the crumbling upper floors were too much for the floor just below it thus the collapse was unstoppable.

So if we go by your theory and the building pancaked wouldn't the towers decelerate because of the floors present directly below the above falling debris?, yet the towers actually accelerated downwards achieving free fall when they collapsed as though there was not a single form of obstructions directly below it, how is that possible?.

 

[Jugger]

There is plenty of examples for non-techs. just like 12 hours long London fire which endorse the basic fact that building fire can't reach to the levels that it melts the structure in mysterious way.

You don't need to melt steel, you just need enough heat to reduce it's load bearing capacity, thus causing it to fail.
This is the exact reason why the twin towers collapsed.

No why would it decelerate? As the weight of collapsing floors increases the building should collapse at even faster rate, thus acceleration of collapse was observed.

Learn physics you idiot the below floors are still standing on the steel structure, no matter how much load capacity is increased as the above debris falls their would still be some form of resistance from the standing structure slowing down the speed of the fall hence making free fall impossible, do you even know what free falls means? free fall is any motion of a body where gravity is the only force acting upon it, and the towers fell in free fall.

Here we go again the same merry old conspiracy theory, for the thousandth time!

Can you explain, why steel of London tower is not melting, even after 12 hours of even more intense fires?
How does those lunatics who were involved in terror attacks, learned all this?

There is one nation on earth who is more eager than Indians to believe US official story with closed eyes
'Iran'
However, no one can beat Iranian followers in Pakistan and Afghanistan, they are simply absolute waste!

Learn physics

exactly, to learn physics, one need to start with passing school with science subjects.
All the posters here are those who are victim of brain wash society.
Obviously, they have no substance in their blabbering.

It is obvious that your upbringing is not civilized hence calling me idiot when my previous post was not insulting to you at all.
Not surprising since the literacy rate is going down.
Where have I used the phrase free fall?
Don't imagine stuff and get mad.

PS: keep believing that 9/11 was an insider job.

The residential building in london has steel covered with concrete, as you know that concrete does not let heat pass easily so the chances of steel weakening is not high.
Also the heat of this fire is not as high as that of jet fuel so the chances of structural failure is minimal.

As for the terrorist being smart or not? I don't really know. But a person committing suicide along with mass murder of innocent people is not just stupid but out of his mind.
I think these loonies got lucky hitting the twin towers.

When steel melts it bends!
doesn't fall freely, like earth has been removed underneath.
and there was concrete, at least that was the residual of molten rocks recovered from demolished site of twin towers!

What explains the explosions in twin towers, at the time of collapse?

 

[!eon]

Still today I say wow that on 911 twin tower fall in a precisely controlled explosive manner
Can any scientist explain ?

Scientist can explain, but than non scientists also explains!
Only person who can filter nonsense out of science, is an engineer.
Most of the world is not engineers and most of the engineers are biased too, for them Muslims are bad guys, so they feel happy anyway when Muslims are in trouble or are killing each other.
This is general brainwashed and divided in world, which has been worked upon from decades and centuries.

Here is a video, which shows how a non-biased brain ask questions from the things he see.
Now watch it full:

The brain washed act hypocrite and turn blind eye from the truth which doesn't suits them.
To make themselves believeable they award them self titles of Think Tanks and in most cases delete truth or have you killed, so that all truth dies with you!

How many highrise have ever collapsed due to fire?

The steel bends and the rivets and weldings fail thus breaking the steel bars at its weekest links. You can see the mangled broken steel beams in images after the crash. The collapse actually accelerated towards the end because the weight of all the rubble was too much for the lower floors to handle.

What explains the explosions in twin towers, at the time of collapse?

Planned explosions did not happen, as no traces of explosive substances was found in the rubble. This is a conspiracy theory to make people believe that 9/11 was an insider job.

Lab testing of ruble, hints at explosive materials were used.
BBC was reporting collapse of tower7 before it did, and you say there was no inside role!
Insurance companies paid $billions to against the insurance policy of twin towers. This insurance was bought days before 9-11. There were bets in stock markets before 9-11 on possible drop in share value of United air etc.
We have no video available of plane hitting pentagon.... and the list goes on.

Here you find evidence of explosive

After 12 hours, wrapped in furious flames of fire from the bottom up to the top floor, this building is still standing.
Just saying.

You think engineers are stupid to put explosive equipment in buildings?
Cold air is pushed into the building by air ducts, there's nothing there to explode like a bomb in compressor.
When you have no idea, how electrical systems are designed and tested in US, don't state nonsense.
Of course electrical systems can fail, due to human negligence and sabotage but than its failure of US standards and their implementation. Still it can't fail in 3 buildings simultaneously and suddenly.

How can cold air be pushing into the building by air duct, when there is a fire inside the building? Hot air expand the air pressure, and cold air at lower pressure will give way to the hot air, in a fire, HOT AIR ALWAYS VENT OUT FROM THE AIRDUCT because it is hyper active.

Cold air can only pump into a building even when they are not on fire, that's why you have air-conditioning and how they work. Otherwise if it was the other way around, you have a unit INSIDE your house generating cold air, and you have duct forcing the hot air out. What you are describing is the complete opposite of the cycle.

What you said does not make sense.

I lived and work in the US, was educated in the US Army Corp of Engineer for demolition skill, and I have no idea how US building, electrical system are designed??

By the way, I do not consider burning for 11 hours in the tower and 7 hours in Tower 7 are "Suddenly" and "simultaneously"

There were no burning debris, explosion on claddings have no explanation.
Building 7 was far.

lol, there are no burning debris? When Twin tower was caught on fire averaging 630 degree?

lol, and the distant between Twin Tower and 7 WTC is only 160 meters. It is not "FAR"

Here's a real picture of twin tower structure. look at the steel size, this can't be effected by a fire ball of airplane fuel.

How do you know? Did you tested the concrete and burn it with Kerosene yourself? Judging from the fact that you do not even know Aircraft don't use petrol, your point worth not much to begin with.

Every concrete, steel re-bar have their weakening point, it's called metal fatigue. There are no "Steel" that can be undamaged by Jet Fuel, considering jet engine combust to at least 1100 Degree Celcius, there will be fatigue when you heat up a steel bar, any steel bar to that level of temperature.

And when you are saying other using media to suit their agenda, aren't you doing exactly the same things? The different between you and me is I back up my claim with evidence and

Hi,

The twin towers were at first hit by a projectile travelling 550 miles and hour and weighing around 130000 + lbs.---that would make the hit at somewhere 70 million foot lbs of force.

So---basically---majority of the iron girders sheared off at initial strike. The aircraft had fuel---highly flamable---there were a lots of elevator shaft in the building---very long shafts---that created a massive wind draft---the fire started---fuel was everywhere---steel girders soaked with burning fuel---.

First the generals stuff caught fire---as the heat increased---then other material caught fire---even concrete and steel caught fire.

A major problem arises when concrete catches fire---this fire is EXTREMELY EXPLOSIVE---you ask why---because---as concrete develops cracks---and any water or moisture that fall on it---goes into the cracks---and retains its position there.

So what happens when concrete heats up and catches fire---the water inside of the cracks heats up---starts boiling---creates steam---massive amount---and that steam wants to escape somewhere thru the cracks---and when the pressure builds up---it explodes the concrete---sounding like a conventional explosive charge---.

And people get confused and think that there are explosive devices involved---.

As the fire burns---it heats up the air---and all these high rise buildings---they are sort of AIR TIGHT to save energy---and as they are compartmentalized by floors and different units in each floor---that buildup of heat also expands air and gases to escape and they blow out the glass windows---which again looks like explosives being used.

So---as the fire is burning hot and the steel girders are getting hotter---the metal starts to lose its integrity to maintain its shape FAR BEFORE reaching its melting point---then bending of metal occurs far before the temperatures reach melting point---.

Now even before we get there---we have to look at another aspect---what weight of aircraft was the building rated for to land on its roof top---helicopters land on the roof---and the roof has a weight rating---but not the rating of the weight of a 737---. The rating maybe for a few thousand lbs helicopter---.

Even president of the US's helicopter would be too heavy to land on the roof top---.

So---what happen when you put 10-15 times the weight on a body that it is capable of handling---it will be crushed under that weight.

I hope I answered most of your concerns. Thanks for the tag.

I always said the same that no one qualify for discussions, based on random news reports suiting their personal bias.
You need to discuss logically, use scientific arguments.
There is plenty of examples for non-techs. just like 12 hours long London fire which endorse the basic fact that building fire can't reach to the levels that it melts the structure in mysterious way.
Jet fuel can simply create a big fireball with causing high temperatures momentarily but that heat can't travel to core of ALL structure, in a matter of seconds.
Twin towers structural design is a whole lot different ball game.

Hi,

So---are you saying that supposedly---a 20 foot tall steel beam standing vertical would stand vertical till it reaches its melting point---which is supposedly 1200* fahrenheit---.

Now there is a heavy load on that beam as well---so what will happen when the temperature reaches---let us say---between 600--800 degrees---.

What will happen to that beam---?
