But you keep forgetting or ignoring the jet fuel fires on the lower floors as told by the official story.
The ones that were NOT in the firefighters transcripts that made it to the 78th floor.

How many times does the 9/11 scientific truth movement have to debunk the same old al-Qaeda conspiracy theories?
The fall doesn't have to crush the stories beneath. It merely has to stress the structural elements until the fasteners pop and the welds break. The impact of that pancaking material will cause the outer vertical members to bow outward, then fly outward violently when failure occurs. There's no need to appeal to explosives to fling material outward from the buildings.
If a story is 4 meters high, it will take an object about 0.9 seconds to fall one story, by which time it will be going 9 m/sec. So once the collapse starts, the overlying structure will be falling at 9 m/sec by the time it has fallen one story. If we crush the collapsing story into rubble half a meter thick and expect the collapse to stop at that point, what kinds of forces are involved? We go from 9 m/sec to zero in half a meter, or 1/18 of a second. However, during that deceleration the velocity is decreasing, and the average velocity turns out to be half of the initial velocity, so the crunch time is 1/9 second. So the acceleration is -9 m/sec divided by 1/9 sec = -81 m/sec2, or about 8 g's.
This is the difference between a static load and a dynamic load. In the north tower, with about ten stories above the impact, the dynamic load was about equivalent not to ten stories but to eighty, nearly the total height of the building. I doubt if the tower at that level was engineered to support eighty stories - why waste the steel? Actually the loads are much greater because the initial collapse involved a fall of about three or four stories, not just one, and the dynamic loads on the points that actually resist the fall - the welds and the rivets, will be far greater. If you try to stop the collapse in the millimeter or so a rivet or weld can deform before failing, you're talking hundreds of g's. In the south tower, where the top 25 or so stories fell, the impact load at eight g's would be equivalent to 200 stories, or twice the total height of the building. Some conspiracy buffs argue that engineering standards require a safety factor several times the actual load on the structure, but the dynamic loads would far overwhelm those standards.
This, by the way, is the reason controlled demolition works at all. If physics worked the way 9-11 conspiracy buffs think, once you blew the lower stories of a building, the upper part would just drop and remain intact. Of course it doesn't because once the building begins to fall, the dynamic loads are far beyond the static strength of the building.

She didn't survive. She actually jumped to her death.
They began jumping not long after the first plane hit the North Tower, not long after the fire started. They kept jumping until the tower fell. They jumped through windows already broken and then, later, through windows they broke themselves. They jumped to escape the smoke and the fire; they jumped when the ceilings fell and the floors collapsed; they jumped just to breathe once more before they died. They jumped continually, from all four sides of the building, and from all floors above and around the building's fatal wound. They jumped from the offices of Marsh & McLennan, the insurance company; from the offices of Cantor Fitzgerald, the bond-trading company; from Windows on the World, the restaurant on the 106th and 107th floors -- the top. For more than an hour and a half, they streamed from the building, one after another, consecutively rather than en masse, as if each individual required the sight of another individual jumping before mustering the courage to jump himself or herself. One photograph, taken at a distance, shows people jumping in perfect sequence, like parachutists, forming an arc composed of three plummeting people, evenly spaced. Indeed, there were reports that some tried parachuting, before the force generated by their fall ripped the drapes, the tablecloths, the desperately gathered fabric, from their hands. They were all, obviously, very much alive on their way down, and their way down lasted an approximate count of ten seconds. They were all, obviously, not just killed when they landed but destroyed, in body though not, one prays, in soul. One hit a fireman on the ground and killed him; the fireman's body was anointed by Father Mychal Judge, whose own death, shortly thereafter, was embraced as an example of martyrdom after the photograph -- the redemptive tableau -- of firefighters carrying his body from the rubble made its way around the world.
Once I read this part, I had to stop reading. Jet fuel (kerosene), or any hydrocarbon fuel, does not explode. Excluding FAE's which are designed to explode, pouring any kind of fuel down a tube, elevator shaft, onto the ground, or wherever, and then igniting it will not make it explode and it doesn't matter how many times you try it.

If you look at all the parts and not single out the instances of fire you see that it was uncontrollable.

Kerosene or other hydrocarbons dont explode?
Thats news to me considering a fuel -air explosion is what powers your car!
When I look at the gas detector in my fire truck has several dozen
different hydrocarbons with the explosive limits in its memory -
including jet fuel aka kerosene. So if not explosive why list them
and their explosive characteristics?
Problem is not the fuel itself, but the mixture of fuel and air . A fine suspension of fuel droplets or aerosol is highly explosive. Seen this
up close and personal in chemical plant when fighting fire of spilled
solvent (toluene). Massive fireball blew out the windows in the room
we were advancing hose line into .

So you would agree then that the official story is wrong then about the large jet fuel fires on the lower floors and sub basements.

Hopefully this helps clear up the fact that not only were people committing suicide before the alleged explosions but we have video,audio and eyewitness accounts.
