That's not correct.they survived for something like half an hour---
What does your post above have to do with the question I asked Rigby5 to explain what was meant by "And the collapsing floors do NOT add more weight,"?the FIRES never went out-----more and more HIGH ENERGY materials reached FLASH POINT and added
to the ongoing INTENSIVE HEAT producing combustion
That's not correct.
WTC1 was hit at 8:46am and collapsed at 10:28am. It stood for about 1 hour and 45 minutes.
WTC2 was hit at 9:03am and collapsed at 9:59am. It stood for about 45 minutes before collapsing.
Not sure where you got "half an hour".
The point being that they DID survive impact of the jets.
I got 1/2 hour because I STOOD AT THE WINDOW AND WATCHED-----I did not look at the clock-----and it happened long ago. The thick white smoke fascinated me. The building stayed "UP" for so long that I was confident that everyone would get out-----then one suddenly collapsed-----and then the second and then the really bad news. Yes---I saw the second impact---it was a GIANT FLASH and then the white smoke rose from the second building. When the second plane hit, I knew it was TERRORISM. Why is the survival on impact "THE POINT"???? It was the continued combustion of HIGH
ENERGY PLASTICS that brought about the fall in my junior high school chemistry educated mind
oh RIGBY----he did not pass Junior High SchoolThat's not correct.

You need to fix you post #882 so it shows the proper quote. Should look like below, not that it was me saying it.oh RIGBY----he did not pass Junior High School
It was the plane impact damaging and severing columns plus the resultant fires that brought down the towers. We are in agreement.I got 1/2 hour because I STOOD AT THE WINDOW AND WATCHED-----I did not look at the clock-----and it happened long ago. The thick white smoke fascinated me.

What does chemistry have to do with Rigby5's statement that "collapsing floors do not add more weight"?oh RIGBY----he did not pass Junior High School

In the first collapse the north tower would have jack-knifed down, the south would have probably collapsed about 5 -10 floors and stopped up there.....tower 7 should have never collapsed.

They also never analyzed the effect the resultant fires from impacts would have on the structure.I knew the buildings would come down. I'm surprised they stood as long as they did. The buildings were willow reeds . Are you familiar with any of the architect's other buildings? Yamasaki never planned for a high speed direct hit. Nor did he expect New Jersey to compromise his design.

I'm right there with you.I despise the conspiracy nuts trying to capitalize on the horrific tragedy.
You sure about that?An impulse, quick sudden force, is not more damaging then a slow and steady force of equal value.

The ratio of stress-induced due to sudden applied axial load to stress-induced due to gradually applied axial load on a bar is 2.
So no furniture, paper, carpeting, etc.?There is not supposed to be any significant combustible in any high rise.
at 180 C even plastic ignites----that combustion isSo no furniture, paper, carpeting, etc.?
Many times.Are you a structural engineer? The north Tower wasn't knocked over. It's spine was cut. Of course it fell down. That's how gravity works.
We're you ever in the WTC?
Yeah, that all burned up in twenty minutes according to NIST.So no furniture, paper, carpeting, etc.?
You're wrong.Yeah, that all burned up in twenty minutes according to NIST.
Consistent with available photographic and videographic evidence, NIST computer simulations capture the broad patterns of fire movement around the floors, with flames in a given location lasting for about 20 min before spreading to adjacent, yet unburned combustibles; some observed instances where fires persisted longer in regions with accumulated combustible debris; other instances of sudden or interrupted fire spread.
with flames in a given location lasting for about 20 min before spreading to adjacent, yet unburned combustibles;
Fires of Short Duration NIST: “The initial jet fuel fires themselves lasted at most a few minutes” [4]. “At any given location, the duration of [air, not steel] temperatures near 1,000 °C was about 15 min to 20 min. The rest of the time, the calculated temperatures were near 500 °C or below” [4].You're wrong.
