On the day of 9/11/2001, the 2 Towers fell, but why did Tower 7 have to fall?

It was structually unsound and had to be razed. So sorry for your loss on that day...

Sorry to hear of your loss.

As it seems you have looked into this, then I needn't tell you that the only explanation that fits the established facts is that it was brought down by a controlled demolition, you don't need to be an Einstein to work that out from some basic physics.

Although many say that there is a scientifically valid, official explanation, that is simply not the case.

There have been quite a few official explanations, which often contradict each other, but none that explains the collapses. Even NIST stops its analysis as the towers are "poised to fall", with not even an attempt to explain the speed of the fall.

As for WTC 7, it was completely ignored in the 9/11 commission.

A'ight nicely i'm going to be honest and admit i'm no architect or something, yet right that's a clarification why Tower 7 fell. A ton of weight replaced into displaced after the twin Towers fell, ensuing in substantial structural injury in the process the WTC complicated. The bases of each and every of the homes have been related. Now, no person's ever performed exams, and no person's ever recreated what its desire to without notice smash 2 of the tallest (and of path heaviest) homes interior the international at relating to an identical time, despite the fact that it form of feels to me that with that lots weight without notice displaced, and with that lots structural injury performed to the beginning place of each and every of the homes interior the encompassing section, it would make sense that different homes, no longer basically those directly hit, might additionally fall. i've got confidence that different homes interior the section did fall, so as that kinda kills the "basically tower 7!" argument. i do no longer think of that Tower 7 replaced into 2 blocks remote from the different towers, the two, yet the two way each and every of the towers have been related to an identical beginning place. There, no insults, basically a directly, rational reason for the autumn of Tower 7. edit: No different homes? ok. nicely then, there you circulate. yet i think of the significant project to bear in mind is that no longer something like this has ever handed off earlier. There are actually not any exams to look returned on and say "nicely, if the twin Towers fall, we've shown, persistently returned in a controlled putting, that this might ensue, or which will ensue, or this might fall, or which will stay." The engineering substantial who spoke back under me has a stable clarification, i replaced into in basic terms putting forward what seems acceptable to me, from each and every little thing i've got study. yet, returned, its unlike we are able to re-create this in a lab and then teach something, the way that maximum conspiracy theorists look to desire issues to be shown (for some reason a lot of those questions desire information to be in capital letters). yet quicker or later, you ought to get off the sofa and say "Dammit they fell, now what am i able to do to make the international a greater effectual place?" rather of questioning if somebody is mendacity to you approximately this minute element or that small discrepancy.

First, the steel frame did not melt. The fire weakend the frames to the point they could no longer support the weight of the building. The steel beams did not need to become liquid, simply heating them caused them to expand and lose their rigidity.

Second, there is no evidence to support your theory that dynamite was used to destroy the buildings. It would require massive amounts of dynamite to destroy the building. Additionally would conspiracy that dynamite or some other explosive was used is fundamentally flawed. In order to carry out such an act it would require the complacency of literally thousands of people ... of Americans to be successful. From the planners who organised the attack, to people carrying it out, to financiers, to explosives experts, to the police and rescue people conducting the investigation. It is simply unreasonable to believe that hundreds if not thousands of people were involved in this, yet no one raised the alarm and no one has come forward.

Debris did damage tower seven, but tower seven was not brought down by debris, but fire that ... like the twin towers resulted in a weakened support system that eventually failed due to buckling caused by the intense heat of the fire.

Also remember, that none of the sprinkler systems were working due to a loss of water pressure and no one was actively fighting the fire.

Finally, depending on the type of steel, it will become liquid at around 1600 degrees centigrade. Jet A burns at temperatures of up to 1000 degree centigrade. Well within the range to significantly weaken even the most advanced steel beams. Ad to it the fact that many load bearing members were destroyed by the impact of the aircraft you end up with just a few beams under massive amounts of stress.

Stress from gravity, pulling on the buildings, stress from the weight of the building being shifted from several beams to just a few, stress from heat from the fires, stress from the swaying caused by the impact of the aircraft, wind stressers ... and many many more.

I don't have a degree in engineering, or architecture, so I cannot explain it all, but clearly there were more forces at work on the trade center than just heat from the fire.

I am; however, sorry for your loss. My brother was there too. He was one of the lucky ones to get out alive.
