9/11 WTC Building 7.. First time in history fire melts steel, and a building falls without being touched?

Question

Steel is melted in blast furnaces that turn it molten. Not by fire in an open area you uneducated fool.

Answer 1

Steel weakens severely at even low temps as correctly pointed out above. That's why we fireproof steel. Unfortunately, WTC was fireproofed with spray-on proofing that can be wiped off w/ your finger

The buildings did not fall at free fall speeds. The outside parts took 10-11 seconds. Free fall would have taken 8 seconds. The inner parts of WTC1&2 (roughly 60 stories of WTC 1 and 40 stories of WTC 2) stood 15 to 25 seconds after collapse initiation before they, too, began to collapse. Thus, nothing unusual was detected. (Do the math yourself distance =16t squared. Make sure you subtract from “d” the height of the debris pile)

In addition, if there were an explosion that pushed all the material downward enough to change the fall time for the bulk of the towers, it would have to be an enormous explosion of such magnitude that everyone would see it occur. You can’t accelerate 1000s of tons of material downward using a “squib”

The jet fuel was not burned in one flash. Experts estimate that the jet fuel burnt for 10 minutes starting a fierce fire of the rugs, desks, papers, etc. This was an unusual fire because it was spread out over wide areas. A usual office starts in one single place. As the fire burned, the floors sagged & pulled in the coutside columns as seen in numerous photos. This is unequivocal evidence of bending steel. Also, as I said, the main cause of the collapse was the damage to steel from the impact.

Answer 2

That was the first time fire melted steel? Hmmmmm.......let me see........how is steel made..........Oh ya! It is melted. So the San Francisco freeway must have been only the second time that fire melted steel, and the roads fall without being touched, huh?

**It doesn't have to melt for a building to fall, it must only weaken it, just like the freeway in San Francisco. Or are you insinuating that is an inside job too? I have witnessed what fire can do to concrete, it causes it to weaken and crumble.

Hey there humanwinnebago...ya... you dork, are you stupid or retarded? Are you serious? You speak as if you haven't read a paper or watched the news. WTC 7 wasn't even hit by a plane, so there goes your jet fuel theory. Do you think with the weight of the building that each floor will actually take only a second to fall. That's just plain idiotic. And by the way, it was 13 seconds idiot. Now go to bed sparky, there is school tomorrow, and lord knows you need it.

Answer 3

Without being touched? Fire melts steel? Where are you getting your "facts?"

Real facts:
At 1200 degrees, structural steel looses 50% of its strength.
The building was extensively damaged by tower debris.
Aside from the tons of flammable materials inside the building, the fire was fed by back up generator fuel supplies under high pressure and burned unattended for over 7 hours.
Any actual melted steel was the result of collapsing energy against an already super heated structure, chemical reactions that you wouldn't understand and the effects of oxy-acetylene at the time of cleanup.

Don't allow yourself to buy into the nonsense - get the real facts and debunk these lunitics. It's a hell of a lot more fun - and you'll have verifiable and valid facts to back it up with.

Answer 4

On March 30, 2007, Popular Mechanics magazine posted a point-by-point response to O'Donnell's claims on its website, which included a scientific correction to O'Donnell's statement about steel and fire: Tower 7 housed the city's emergency command center, so there were a number of fuel tanks located throughout the building—including two 6000-gallon tanks in the basement that fed some generators in the building by pressurized lines. The working hypothesis is that this pressurized line was supplying fuel to the fire for a long period of time. Steel melts at about 2,750 degrees Fahrenheit—but it loses strength at temperatures as low as 400 F. When temperatures break 1000 degrees Fahrenheit, steel loses nearly 50 percent of its strength. It is unknown what temperatures were reached inside WTC7, but fires in the building raged for seven hours before the collapse.[44]

google it and read the whole thing. It also states how, while it was not known at the time, when crews came in later WTC7 actually was hit by extensive debris from the North Tower.

Answer 5

It is one thing to prove how crime is committed, but totally different matter to prove WHO did it.



Even if you're right about all these. How does it exactly prove the US gov did it?

After all it could be terrorists that planned thermite and all that. Right?

I guess what I'm saying is even if you are right that WTCs were demolished, this doesn't necessarily prove the gov was involved.

This is like proving a victim has been shot with 3 bullets and after that you just assume Bob did it without any evidence.


Not to mention all these WTC7 stuff is just wrong. WTC7 had massive damage. And rescuers were not allowed in WTC7 because it had such heavy damage that it started to lean and became unsafe for anybody to go in.

Answer 6

I belive it man!! These people are retarded. Ok lets say the fire did weaken the steel. ok good how did the building fall at free fall speed????? Lets give the pancake theory merit ok... Give each floor a second yes a second to hit the next and fall...thats pretty damn fast, theres about oh lets say just 100 floors although there were way more for shits and giggles.. thats almost a minute it would have taken. How do you explain seven seconds?? Its physically impossible. Unless the lower floors were damaged as well already or weakened. and dont say the jet fuel poured down the elevator shaft, did you see that giant ******* fireball when the plane hit?? Theres your jet fuel asshole. Burnt up and gone in seconds when fuel ignites it doesnt burn part of it off it all goes in one big flash, so there was no left over fuel to burn.

Answer 7

Of course the fire didn't melt the steel, I was in that building, having at it with a pickaxe!!!!

Steel doesn't have to melt to collapse, all it has to do is get really, really hot. Jet fuel burns really, really hot.

EDIT: I think this is also the first time that an airplane has crashed into a building, right? So we really have no expierence with it.

Answer 8

Stop parroting Rosie. It's embarrassing.
I recall a truck overturning under a bridge in california a couple weeks ago. Not only did the ensuing fire melt the steel bridge above it, it crumbled the cement.
I can only imagine what 20,000 gallons of high octane jet fuel poured down elevator shafts would do. You should try imagining too, uneducated fool.

Answer 9

It only needs to weaken Einstein. Do you suspect that two 1/4 mile high skyscrapers with 110 acres of floor space (each) falling at the base of #7 had anything to do with its collapse?

Answer 10

Don't you get tired of asking this same stupid question over and over? We were all hoping you had grown a brain since the last time.
P.S. Just what do they use in steel mills to melt steel?
