London fire vs. 9-11 fire

[jhungary]

Please watch this lecture when you have the time.

Didn't watch the whole clip but I do know this "High School Physics" teacher claim about WTC 7 being free fall, and his claim "Naturally Collapsed structure cannot crash at a free fall speed" is actually been debunked by physics and engineer community.

Following is an explanation from an Engineer.

Even when explosives are used to bring down a building, they’re only used to begin the movement of the building. Best practice is to use the absolute minimum amount required to move part of the building, and when that part impacts the rest of the structure it will overload it and cause massive failures throughout. Stress waves can move through a solid material at the speed of sound, so in very high shock loads a lot of structural members can be crushed or buckled throughout the structure very rapidly.

Effectively if the overload is high enough (which it will be) floors lower down (and higher up) can fail ahead of the falling debris, meaning the collapse isn’t significantly impeded on the way down. Some of the kinetic energy of the fall will be absorbed by the structure, but once enough mass is on the move it can be a very uneven struggle. In cases like the WTC you have huge mass descending, so you’d expect the lower floors to put up minimal resistance.

Bottom line, falling buildings tend to fall at the same sort of speeds whether explosives are used or not. You can use explosives to initiate a collapse, but they’re not required to make one collapse quickly, in fact doing so would be extremely difficult, could in no way shape or form be concealed and usually wouldn’t make much difference. It would require massive and extensive preparation and miles of very obvious det cord connecting a large number of individual charges. Not a realistic suggestion.

TOPIC: London fire vs. 9-11 fire
NOT a rehash of all debunked conspiracy theories re. 9/11, thank you.
It is very disrespectful towards victims and the ones they leave behind.

THE GRENFELL TOWER BUILDING WAS RECENTLY REFURBISHED AND, TO MAKE IT MORE ATTRACTIVE TO VIEW, FITTED ON THE OUTSIDE WITH SHEETING (WHICH APPARENTLY BURNED LIKE CRAZY). WHICH IS A BIT DIFFERENT FROM SUFFERING AN AIRCRAFT IMPACT THAT CAUSES MASSIVE INTERNAL DAMAGE AND A HIGH TEMP AVIATION FUEL FIRE ON THE INSIDE. ALSO, THIS BUILDING ISN'T LIKELY CONSTRUCTED IN THE SAME WAY AS WTC BUILDING WERE (IT BEING SUBSTANTIALLY SMALLER, LESS TALL, JUST 24 FLOORS RATHER THAN 110). IT ALSO SERVES A DIFFERENT PURPOSE (ACCOMMODATION RATHER THAN OFFICES) WHICH PROBABLY LEADS TO A DIFFERENT INTERNAL STRUCTURAL LAYOUT.

JUST SAYING...

"Grenfell Tower was recently fitted with exterior aluminum cladding. Christopher Miers, the managing director of Probyn-Miers, a forensic architecture firm that examines buildings that are defective or fire damaged, said: “It’s a possibility that there are areas in the external wall system that played a role and it’s an area that would need to be considered.”

Whether the cladding had a role in this case was not clear, but such cladding, which often consists of aluminum sheets sandwiched over some kind of insulation, has been seen as a factor in past blazes, including three major high-rise fires in Dubai.

The United States and Britain have tougher regulations on the potential flammability of internal material used in cladding, but other factors — such as how panels are made and installed — could come into play.
...
David King, a building engineer in Maidstone, England, said the cladding might have helped the blaze leap from floor to floor.

“I’ve seen how the flames were coming out of the windows and going up the outside, so that’s one possible explanation,” he said.
...
In May 2016, the building underwent a $12.8 million renovation, including the cladding, double-glazed windows and a communal heating system.

9 11 towers were made to with stand airplane impact? I watched some documentary back in the day on them about how they were built.

Correct.

"Aircraft impact

The structural engineers on the project also considered the possibility that an aircraft could crash into the building. In July 1945, a B-25 bomber that was lost in the fog had crashed into the 78th and 79th floors of the Empire State Building. A year later, another airplane crashed into the 40 Wall Street building, and there was another close call at the Empire State Building. In designing the World Trade Center, Leslie Robertson considered the scenario of the impact of a jet airliner, the Boeing 707, which might be lost in the fog, seeking to land at JFK or at Newark airports. The National Institute of Standards and Technology (NIST) found a three-page white paper that mentioned another aircraft impact analysis, involving impact of a jet at 600 mph (970 km/h), was indeed considered, but NIST could not locate the documentary evidence of the aircraft impact analysis."
https://en.wikipedia.org/wiki/Construction_of_the_World_Trade_Center#Aircraft_impact

This is in relation to 1 WTC and 2 WTC, the Twin Towers. The original World Trade Center complex included four other smaller buildings constructed during the 1970s. 3 World Trade Center was a 22-story building, home to the Marriott World Trade Center (designed by Skidmore, Owings and Merrill in 1978–79). 4 World Trade Center, 5 World Trade Center, and 6 World Trade Center were all 8–9 story buildings designed by the same team as the Twin Towers, including Minoru Yamasaki, Emery Roth & Sons, and Skilling, Helle, Christiansen, Robertson. The 47-story 7 World Trade Center building was built in the mid-1980s to a design by Emery, Roth & Sons.

All those who disagree with the official story regarding 9/11 are extremists and purveryors of hatred. They should not be allowed a platform to air their spiteful views (!)

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

@MastanKhan
Your comments?

There was that building in Iran that collapsed by fire.

Corner damage means nothing to twin towers.
There was inner ring of structure as well.
Some one planted some explosives there by design, otherwise plane didn't hit there. Why than such superficial damages were seen on both buildings alike?



It was fire and heat, which lead to collapse of all 3 towers.
Specimen from collapse site were examined in labs and I'm referring to that.



What caused identical fires on tower 7 and what was its significance?


there you go.

Debris from the Twin Towers caused the fires. Especially big debris enough to damage it to the extent it will collapse as well. Debris can do alot of damage. WTC 7 wasn't far enough to not get hit by it either. Same for other buildings. Some got hit by debris, but you can see WTC 7

got hit hard.

Also, London Grenfell tower is a structural fire, Twin Tower is a fuelled Flash Fire....

It is non-comparable.

Conspiracy theorists ejaculating on this thread . Everything is a napak Yahoodi Saazish .

People also need to realise the theory of "Free Falling" does not make sense.

Anyone who have demolition experience will tell you that if you want to rig a 47 story building and have it "Free Fall" to the ground, you would have to rig the building on every column and every floor of explosive, so when you detonate the building, it will collapse at the same time and the building will fall at a free fall speed, WTC 7 have 8 loading beam every floor, meaning you will have to rig about 32 charge each floor to totally collapse the building. (4 per beam so they will fall exactly downward and each blast compensation with each other, if you put 1 in each beam, the beam will fall to the other side of the charge. SO it have to be 4 charge per beam to collapse it downright)

Then 2 things does not make sense.

1.) How can you rig this detonation in 7 hours? You need to bundle the explosive, lay cable, lay det cord, prime det cord, laid charge, cut and connect the explosive in each floor. And you are talking about 1504 charges to be made, unless you have a team of 1000 demolition expert. It would take days, if not week just to make this happen.

2.) How can this project be unknown to the public? You are talking about tons of explosive, mile of det cord, miles of cable, hundred of demolition expert, going in and out of the building, floor by floor, all this when the building is burning and people are watching, audience would have know people are working on a building placing explosive, because you have to run up and down inside the building to place the charge you need. How can nobody see it when there are thousand of people lining up watching the tower burn?

lol....

what about larry silverstein, bomb under washington bridge, five dancing israelis, passport found under rubble, thermite claims, news talk about collaspe while still standing, left over metal quickly sold to china, abestos,firemen claiming explosions. dancing israelis were there to document it statement.

I saw dancing Palestinians. That could be significant.

There has been a good amount of coverage about Grenfell Tower burning down in London. Yet, few articles are mentioning that the 24-story high rise was a publicly subsidized building for low-income and disabled residents. Reports are coming out that there was an allegedly faulty alarm system, no central sprinkler system, and that the building was covered in cladding that help spread the fire quickly. We can say it was an accident, we can say this was a perfect storm, we can say firefighters were heroic when responding, but what we need to be saying also is how society treats poor and disabled people. This was a building where poor and disabled people lived -- not where rich people lived -- and safety measures were not in place because their lives and their humanity are always secondary to politics and profit.

This isn't just an issue in England, but rather across the globe where a person's self worth and treatment is dependent upon their earnings/bank accounts. Look at the photo for a minute. Truly disgusting that we let poor people, including poor children, burn to death in one of London's richest neighborhoods.

come on do better than that instead of cheap one liner. I did not create these conpiracies these are written by white americans not muslims ok. why dont you search aaron russo who says the rockfellers expose this themsleves to him.

I saw dancing Palestinians. That could be significant.

Thier was no palestinians dancing but there were israelis celebrating than they got interviewed, and they say we were there to document this. uss liberty will open your eyes.

So If a random white guy says something about "rockfellers" and you jump into yahoodi sazish bandwagon you need to take your medications. Timely as well I might add .

Also this Israeli celebrating thing has been debunked so many times but carry on if it helps you to sleep in night believing that .
