jet fuel = diesel fuel...

Dude, we've been ALL over this. This experiment is about as valid as saying gas won't burn because it doesn't ignite from a cigarette.

Dude, regardless, jet fuel or diesel fuel or a normal office fire will at best weaken the metal within area of impact, but the floors that are below and further away from the heat source should have been as structurally stable as they were before. Not enough heat to cause the metal on the lower floors to yield. Notice very carefully that I use the word "yield" and not melt. Yet another distinction that I have been making before, yet most of you clowns overlook.
Have you thought about the top floors crashing into the lower floors with more and more force
Yes, and the floors collapsing on to the floors below them would have eventually gotten to stronger and stronger floors as it collapsed because those lower floors would have been a lot further away from the major source of heat, which should have caused the collapse to stop at some point. At the very least, we should have seen maybe the top floors possibly collapsing, but the majority of the lower floors should have still been standing. But instead, what we got is a complete collapse on 3 different buildings, 2 hit by planes and one hit by nothing.

Those stronger floors are taking on more and more weight.
Stationary.
Try holding a 25-lb object. Now, have someone drop that same object from the floor above you, better yet, several floors above you and try to catch it. It should be easy because, you know, its the same weight.
Wrong.

No, the actual weight does not change, but the impact load becomes significantly larger as the weight of each floor is added to the decending mass. An impact load the structural clips were not designed to carry. It becomes much like using a 9 lb. sledge (instead of an axe) to lop off branches of a small tree.

I have explained this time and time again, but let me try yet one more time.
As each floor collapsed onto the floor below it, it would lose kinetic energy on each collision and the kinetic energy lost would instead go towards the necessary force to buckle/fail the joints or supports of the floor below it. Eventually, as the momentum started to reach lower floors (floors that are stronger because they are further away from the heat source), you would need more energy in order to cause a failure. What you should have had is (maybe) the most affected and damaged floors near the impact zone of 2 of the buildings caving in and eventually stopping about midway down. But it should have never resulted in a complete and total collapse of the building.
Still not sure how you are going to explain the complete and total collapse of Building 7, however.
Nothing?!! NOTHING!?? NOTHING?????
You have already had your tin foil hat handed to you about this very thing in the 9/11 thread.
It has been computer modeled and shown that the 3D debris footprint of many! many! many! large pieces of the nearest tower that easily penetrated the exterior curtain wall catastrophically damaging the structural integrity and carrying burning debris that ignited fires in that building covered VIRTUALLY the ENTIRE NEAR FACE of the third building. It was a "dead man walking".
The weight of the 25 lb object didn't change in either scenario, whether it was in your hand or dropped from above you.
If you are not going to use the correct terminology or understand the mechanics behind it, then maybe you need to remove yourself from the discussion. You sound silly.
Youre way too concerned about distance from the heat source. The distance from the heat source doesnt matter when all those floors come crashing down.
Also, no, as I previously stated stated, the weight doesnt change. How you, or rather the building handles the weight, does.
It sure as hell does matter when you are talking about a catastrophic failure. Outside of a controlled demotion, that building should not have failed completely in the path of most resistance (straight down).
