i can counter that link with this link http://www.prisonplanet.com/911.htmlGo to this webpage and then come back here and just try and attempt to give rational explanations or debunks to any of the stuff on that page, 🙂

FACT: Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F).That fact coupled with multiple demolition experts who say the only way the buildings could of collapsed the way they did is by cutting charges being placed on the support struts and the BOTTOM of the structure.
That would explain why public and news reporters eye witnesses saw and heard multiple explsoions at the base of the structure and it also explains why the firemen felt, seen and heard multiple explsoions go off at the base of the the structure also
what more do u want?
It is known that structural steel begins to soften around 425°C and loses about half of its strength at 650°C.4 This is why steel is stress relieved in this temperature range. But even a 50% loss of strength is still insufficient, by itself, to explain the WTC collapse. It was noted above that the wind load controlled the design allowables. The WTC, on this low-wind day, was likely not stressed more than a third of the design allowable, which is roughly one-fifth of the yield strength of the steel. Even with its strength halved, the steel could still support two to three times the stresses imposed by a 650°C fire.
The additional problem was distortion of the steel in the fire. The temperature of the fire was not uniform everywhere, and the temperature on the outside of the box columns was clearly lower than on the side facing the fire. The temperature along the 18 m long joists was certainly not uniform. Given the thermal expansion of steel, a 150°C temperature difference from one location to another will produce yield-level residual stresses. This produced distortions in the slender structural steel, which resulted in buckling failures. Thus, the failure of the steel was due to two factors: loss of strength due to the temperature of the fire, and loss of structural integrity due to distortion of the steel from the non-uniform temperatures in the fire.

Oh look, an objective, reputable source disagrees with you.
Are all your sources going to come from conspiracy theory websites? Find one site not conspiracy linked that backs up your claims. And don't pull that "the information is taken from other sources," because the assholes never cite sources.
Fact: Firefighters said "it sounded like a battlezone... as if explosions were going off all around us." Pretty easy to twist those words around.
Still no names of firemen claiming to have seen a controlled demolition, Deano. And please explain the brother-in-law who saw no demolition crews around WTC 7 while he was patrolling.
