Collapse due to steel weakend by fire?? Rubbish! [View All]

According to the official theory, the Twin Towers collapsed due to the structural steel being weakened by fire. In other words, they collapsed due to fire. if that's the case, then how come no modern high-rise, before or after 9/11, has ever collapsed because of a fire?? If that's the case, 9/11 would be the first time in history a modern steel building has ever collapsed due to fire or steal weakened by fire.




For example, why didn't this building collapse?



1991 One Meridian Plaza fire in Philadelphia, raged for 18 hours and gutted 8 floors of the 38-floor building. 1988 First Interstate Bank Building fire in Los Angeles, which burned out of control for 3-1/2 hours and gutted 4 floors of the 64 floor tower. Both of these fires were far more severe than any fires seen in Building 7, but those buildings did not collapse. The Los Angeles fire was described as producing "no damage to the main structural members".


Or this one?




Or this one?



Skyscraper in Madrid Spain burned for almost 24 hours, no collapse.

These out of control infernos burned much more longer and much more intensely,
but remained standing.



Compared to this weak, under control smoldering fire, burned less than an hour,
which caused the WTC towers to collapse but the others are standing!??
