The fire`s werent that hot...

You only saw black smoke generated from cool fires who do not have much oxygen...

Lack off oxygen means that the temperatures couldnt exceeded the 700 Degree centegrade limit...

Steel only melts at 1500 degrees centegrade...

Oh, iff you didnt noticed yet. The towers where built in mind off a plane crashing into the towers...

Because the towers would be so high and NY has many big airports, so the change off a plane hitting the WTC towers in dense fog was big...

The fire is still one of the main reasons WTC fell.

Agreed.

I lost several IQ points reading the last page of this thread. Will you guys politely return them if you find them?

well theres a good chance that the Freedom Tower will be attacked sooner or later because terrorists know what the building means to us and that its being built at the World Trade Center where the orginial towers once stood, so i think it will always be a target and there might even be an attempt to destroy it, but who knows anythings possible

You're right about the smoke and the melting point of steel. But you probably didn't knew that unprotected steel loses 50% of its strength at 400C. From 235 N/mm2 to 115 N/mm2 for normal European structural steel. This way it became unable to support the weight of the concrete floor and the office furniture.
The steel of the WTC was covered with fireresistent materials to withstand these kind of fires, however due to bad maintenance the protection was dameged. This way the fire could heat up the frames which supported the floor.
Further was the tower designed to withstand crashes from the biggest planes by the time the tower was designed.

so do you guys think if the Freedom Tower was hit by an airplane the same size or larger than the ones that hit the Twin Towers, and was flying at the same speed, it would collapse the building?. because it seems like the Freedom Tower isnt going to be any stronger than the Twin Towers

if the Airbus A380 was to hit the Freedom Tower at 500 mph it would be devastating, the wingspan on that thing is almost 300ft, which is wider than the Freedom Tower, so if it was to hit at a low point on the building it would probobly collapse it

This thing should be pretty strong.

Isn't the first two hundred feet of the Freedom Tower going to be reinforced concrete? That sounds like it would anchor the rest of the structure pretty well, and I'm almost certain that they'd put extra fireproofing and supports to defend the tower against an attack, after all, it is an icon.

Stupidest thing I've heard. The Freedom Tower was designed to withstand impacts from double-decker jets, not like a terrorist would ever get into a cockpit again w/o getting shocked to death.

Why are we all talking about such a morbid subject? We should be looking forward to this great tower rising, not how it could possibly fall victim to a terrorist attack!
All the plans are in place, it's certainly much more prepared for an attack than the last WTC.

Come on folks, look to the future with optimism

So wait your implying we s hould wait till the next attack to see if this building will survive a plane flying into it? Where do you people get these ideas. Reread what you said and rephrase that in a more sensitive way.
