Three Buildings collapsed by fire?

For the first time in history, fire caused 3 buildings to collapse. Nowhere in history had this happened before. As recent as in 2005 a 32 storey building in Spain burned for 2 days and the whole structure remained intact. So why can 3 buildings have collapsed due to fire in NY during 911?

Some say that the planes crashing into the Twin Towers weakened the structure, causing it to collapse. But these buildings were in fact designed with the possibility of a Boeing 707 (the biggest plane during construction) to crash into the building keeping the structure sound. The Twin Towers were designed with its core strength down the centre of each building. If those planes took out the outer beams, the building would have remained intact. Some people say the heat generated by the jet fuel caused the steel to weaken. But jet fuel doesn’t burn at the required temperature to have weakened the steel and in video footage you can actually see people standing at the gaping hole where the plane entered the building after impact. So how could there have been hot burning, steel weakening fires ragging as suggested by the “experts”?

So what caused these two buildings to collapse? Also the 3rd building, building number 7 in the complex (a 47 story building); collapsed without any aircraft hitting its structure. What makes this event even more peculiar is that CNN and BBC reported that the building has collapsed before this has actually happened. Who supplied these news networks with this information that the building collapsed, how was these people to know it would also collapse unless someone knew it would be demolished? Are they the same people that supplied the news networks with the information that Bin Laden was responsible? That a couple of people living in a cave in Afghanistan planned and executed this enormous feet? They were able or lucky that the air defence was called to stand down and also for some reason managed to catch the automatic air defence system off guard at the Pentagon. This system was supposed to deploy anti-aircraft missiles if a non-military aircraft ignored the non fly-zone rules.

I find it even more surprising that although so many gaping holes exist in the whole 911 “official” version and yet no main stream news media are doing any “investigative” reporting on these suspicious events. Are they also being told not to report this? You would think that an enormous, world changing event like 911, would be scrutinized and any strange and unexplained things would be reported. So the general public are oblivious to the lies told and that our history books will be written about a day when the world changed, that “terrorists” high jacked 4 planes, that 3 buildings collapsed due to fire, that the small hole at the Pentagon was made by a Boeing, that the scattered remains of flight 93 was not shot down, but brought down by the passengers. If our history books tell us these lies, then I would question many of the “official” versions told by news networks and schools.
