This is a fact, so to keep arguing that the fire could have weakened the steel is fruitless. Knowing that, if it was the force of the planes cutting through the steel that dropped them, it wouldnt have taken over a hour for them to fall. The steel was designed like a screen, when those planes hit, it was like pushing a thick pencile through a screen, the rest of the steel was intact. | ROTFLMAOL!!! Grace, you're describing the lower floor steel...The UPPER steel framing was 18 inch WIDE H-Frame flexible steel. A much lighter and less fire-resistant steel.
And it wasn't like 'a pencil pushed through a screen'...In fact, before the towers fell, everyone could clearly see the huge RIPS into the buildings the planes had made...In fact, the plane had practically cut completely through one complete side of the one building, where only 3 corners weren't torn from the impact and the other building had 2 corners greatly damaged, leaving only 2 support corners intact. That doesn't include all the complete destruction of the frames inbetween those corner struts and halfway into the other side of the one building...
The weight of 30+ floors above that tear were already weakening the framing...Despite the fact that they used a lighter steel because of the concrete and glass weight added into it...Then the fires that were started below and above those tear points adding to it's destruction.
Extreme damage to the 18 inch standard H-frame (by standard, that means it's approximately only 4 inches thick along the H-frame shape) steel framing.
No where near the 'thick, fire-resistant heavy steel' frame work you cling to, that was used on the ground levels only and were the only thing that survived the towers falling, except for being bent inwards and missing their siding....Which incidentally was built IN and above the level of the fall hole, of which the towers themselves were set several IN feet and UP with the more wind resistant, lighter flexible steel.
And that darling, is where your conspiracy people get you to fall for their 'story'...They tell you the building material used on the lower floors giving you the impression that it was used throughout the building, not informing you about the other materials used to build ABOVE that level...They HAD to use a lighter steel that would allow to build that high as well as ensure the structure itself could withstand high wind speeds.
Like I said Grace...You're talking about something you really don't know a thing about, except for what the conspiracy creators have led you to believe about it.  |
