apparently buildings just fall over.

[Wiglaf]

Buildings don't generally just fall to pieces. Even when they're on fire. We've been media-conditioned to believe that fire can kill steel frame buildings, even though every steel frame building in history (before 9/11) that had a fire-some even over multiple floors for over 24 hours didn't fall down!

cause it was rigged. :|

Dang things like this only happen over there.

I wanna see an earthquake aftermath shot of the buildings there, see if even one stands.

This building suffered a foundation failure and the building tipped over. Like physics dictated it would. :up:

Thanks for the physics lesson, but I just don't have to much confidence in Chinese building code/construction.

And you do remember that the WTC towers kind of got hit by a couple of planes going around 500mph right?

Don't think too many buildings had that happen to them before 9/11.

[nando]

over here if the population is the same as China, it would be the same thing.

yes no value for life because of over population. We see that example developing in the united states as well. Not enough jobs to meet the demand.

We need another world war to control the human population. Yes... its very radical, but it is a problem that will eventually turn into a world war whether we like it or not.

dude, tell your mom not to let you into the meth lab any more. you're scaring me.

There are people living in that building still, space is limited.

Actually it has happened. The Empire State Building was hit by a B-25 bomber in 1945. It obviously didn't fall down.

And don't forget that WTC 7 fell down all by itself after being on fire for several hours. No plane ever hit it. It fell straight down at near free fall speed into a big pile of pulverized material. Physics states that can't happen unless the material between the top and bottom is somehow removed. Remember: this was the first time in modern building history that a building fell down in such a manner (supposedly without explosives) and there was no forensic investigation! No tests of the materials! It was all hauled off and recycled. That is irresponsible at best. Criminal at worst. Not saying it couldn't possibly have happened, but it isn't very likely....

This is what buildings really look like when they collapse:



Notice anything? Hint: they're largely intact-as in they didn't turn into a pile of pulverized material.

The WTC didn't collapse like other buildings because the upper floors failed due to the heat. This resulted in millions upon millions of tons of steel and concrete slamming into floor after floor. Other buildings that fail usually collapses at the base because of stress leaving messes you posted above

I am speaking of WTC 7. Nothing hit it. Fires were smoldering. Heat from office fires are not hot enough to melt steel. Nor is diesel fuel, nor aircraft fuel, nor.......

Official report says:

The extensive three-year scientific and technical building and fire safety investigation found that the fires on multiple floors in WTC 7, which were uncontrolled but otherwise similar to fires experienced in other tall buildings, caused an extraordinary event. Heating of floor beams and girders caused a critical support column to fail, initiating a fire-induced progressive collapse that brought the building down.

Progressive collapse? Straight down? At free-fall speed? Extraordinary indeed.

You dont have to melt steel to weaken it. You just have to get it hot enough to start to soften and accelerated fire (kerosene, diesel or just infused with extra O2) will make is steel soft enough work with a small hammer and small amounts of force. Think if you do the same but pile 100's of tons of structural loading on that heated steel.

Come on here you are smarter than this you are not one of those 9/11, The govt did it, black helo's, there is no way that could have happened like that with out charges in the building, are you?????

Not "officially".:up: But you have to admit, IF the official explanation is true, and the sprinklers in the building couldn't even slow the destruction longer than the few hours (in spite of no other building in history failing from being on fire for many more hours), then every other building of its size is a ticking time bomb. Add to that the utter lack of forensic investigation on the actual failed material, and you have some pretty large holes in the "official explanation".

How many cameras are pointed at the Pentagon 24/7 and there has never been a single clip shown of an actual, recognizable 757 approaching the building? C'mon-you are smarter than to buy the lie given the utter lack of evidence aren't you? I'm not saying a plane didn't hit the Pentagon, but the government says it did. Where's the proof? That's all I'm saying......

Come on Mr. Physics guy, let's compare a B25 Mitchell bomber to a Boeing 767.

B25 / 767

Length: 52ft / 159ft
Wingspan: 67ft / 156ft
Wing Area: 610sq ft / 3050sq ft
Empty Weight: 21,120lbs / 181,610lbs
Fuel Capacity: 974 gallons / 23,980 gallons
Max Speed: 275mph / 568mph

767 goes nearly twice as fast, weighs nine times as much, carries 24 TIMES the fuel, and is just generally FUCKING HUGE when compared to the B25. Also keep in mind that the B25 was being flown in heavy fog by a US Army pilot, and the 767 was deliberately slammed into the towers by terrorists.


Force of Impact: 4,379,375 tons / 95,254,250 tons

And 21 times the impact force.

WARNING: Not for short attention span types! :-)

Come on Mr. Physics guy, let's compare a B25 Mitchell bomber to a Boeing 767.

WTC Towers were built to withstand a 600MPH impact from a Boeing 707. Compare that with a 767 and you'll find them very similar.

John Skilling, one of the two chief designers stated:

“The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC-8 ) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.”

Frank A. Demartini, on-site construction manager for the World Trade Center, stated on January 25, 2001:

The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting.

So these two buildings failed in exactly the same way from impacts they were designed to absorb, and you still believe "they just fell down?

Familiarize yourself with the Law of Conservation of Momentum and review the collapse of the Towers. Unless you believe Santa Claus really can fly around the whole world on Christmas night, you'll find it increasingly hard to believe that a cannonball dropped in clear air from the roof of WTC 1 would've beaten the roof it was dropped from by only a few seconds. Especially since the roof would've had to go through the entire rest of the building to get there.

Lastly, does it not bother you that even the official NIST report admits:

The Investigation Team then defined three cases for each building by combining the middle,
less severe, and more severe values of the influential variables. Upon a preliminary examination
of the middle cases, it became clear that the towers would likely remain standing. The less
severe cases were discarded after the aircraft impact results were compared to observed events.

The more severe case (which became Case B for WTC 1 and Case D for WTC 2) was
used for the global analysis of each tower. Complete sets of simulations were then
performed for Cases B and D. To the extent that the simulations deviated from the
photographic evidence or eyewitness reports [e.g., complete collapse occurred], the
investigators adjusted the input, but only within the range of physical reality. Thus,
for instance,…the pulling forces on the perimeter columns by the sagging floors
were adjusted... (NIST, 2005, p. 142.)
The primary role of the floors in the collapse of the towers was to provide inward
pull forces that induced inward bowing of perimeter columns. (NIST, 2005, p. 180)

They couldn't figure out how it fell down, so they "adjusted the inputs" until it did! How nice!
