14 years and counting and the "OS" remains standing to this very day. After all, structural and civil engineers, architects, firefighters and demolition experts have confirmed that fire, in conjunction with impact damage, was responsible for the collapse of WTC 1, WTC 2, and WTC 7, and that is official.
Interesting. Thank you. I read somewhere that just the office equipment and furniture burning could reach as high temperatures as the jet fuel. Do you know if this is true?
In common circumstances, the maximum temperature of a fully developed building fire will rarely exceed 1800°F. The average gas temperature in a fully developed fire is not likely to reach 1500°F. www.aisc.org...
This video from a Nat Geo documentary demonstrates that jet fuel can fail the steel beams used in the twin towers:
14 years and counting the OS fell apart when real science was applied to the WTC demise.
Disinformation Killed 9/11 “Truth”
By 2009, the 9/11 “Truth” Movement was so inundated with disinformation that it had become a laughingstock.
Architects Shy From Trutherism
Architects didn't show up for a 9/11-architecture-conspiracy documentary screening—and the AIA doesn't want its name associated with Trutherism.
Influence of temperature on the strength of metals
Some common types of steel lose 10% of their strength at 450 C (840 F), and 40% at 550 C (1022 F). At temperatures above 800 C ( 1475 F), it has lost 90% of its strength.
Other types of steel are made to stand higher temperatures before losing 10% of their strength, but they are much more expensive (and are weaker at room temperature).
And there are types which actually get stronger, up to 450 F (but then get a lot weaker at higher temperatures

Jet fuel burns around 1800 degrees not hot enough to weaken the WTC steel, and not in one hour.
Looking at the facts, science has been used to make a mockery of the Truth Movement. In case you missed it.
Just to let you know that you video has been debunked. Demo explosions make a lot of noise that can be heard from miles, and yet, there is not a hint of an explosion as WTC 1, WTC 2, and WTC 7 collapse.
That's correct. After all, I have annealed aerospace steel to the soft condition at only 1000 degrees F., which is below the melting point of aluminum.

The fact is, The WTC steel was not sitting in a vat full of jet fuel.
The fact was all the jet fuel was spread everywhere in the impacted zone and burned off in a matter of minutes.
The fact is Firemen said there were pockets of fires in the impact zones and all the jet fuel was burned off, they believe they could have put out the firers.
