The top of the building does not have to fall to compress air inside the building, we did not know what was collapsing inside.
energetic dust ejections are first seen while the top is only slightly tipping, not falling.

The building is obviously compromised, so we do not know exactly what is falling down inside to produce the air being expelled.

We are discussing what is witnessed from the outside of the collapse and what is visibly in the videos. I do not understand what you are talking about from the inside?
What happened inside, the air compressing, is what caused the puffs of dust seen on the outside...

What does a "normal collapse" of a large office building look like, Informer? How would you know if a collapse wasn't "normal?"
I am sure you know that anyone can pull up hundreds of videos of buildings collapsing from earth quakes, or from faulty design online to see how buildings fall without the use of demolition.
Here is something I would like you to read, that are facts concerning the WTC demise.
Collapse Features Characteristics of the Twin Towers' Destruction and What They Show
The total destructions of the two towers were almost identical. The most apparent difference is that the top of the South Tower tipped for a few seconds before falling, whereas the top of the North Tower telescoped straight down from the start. Here are some of the principal characteristics of the destructions, based on study of the surviving evidence.
The cores were obliterated. There is no gravity collapse scenario that can account for the complete leveling of the massive columns of the towers' cores.
The perimeter walls were shredded. No gravity collapse scenario can account for the ripping apart of the three-column by three-floor prefabricated column and spandrel plate units along their welds.
Nearly all the concrete was pulverized in the air, so finely that it blanketed parts of Lower Manhattan with inches of dust. In a gravity collapse, there would not have been enough energy to pulverize the concrete until it hit the ground, if then.
The towers exploded into immense clouds of dust, which were several times the original volumes of the buildings by the time their disintegration reached the ground.
Parts of the towers were thrown 500 feet laterally. The downward forces of a gravity collapse cannot account for the energetic lateral ejection of pieces.

This is exactly what I observed when I watch the videos of the the WTC 1 & 2.
There is way to much energy involved when watching the WTC fall. Would you agree?
The building collapsed too fast for demolitions; clearing a floor between 150 and 200 milliseconds would require noticeable amounts of explosives. Thermite is far too slow and not timable. Gravity is the only explanation.

I disagree.
That is not what I see.

I disagree.
Interestingly the fist tower to fall, fell after 55 minutes after being struck, there was not enough heat that could have weakened the steel since the WTC steel was tested to handle 2500 degrees for several hours before the steel would weaken.
The questions I wanted to address here are what was visibly in the WTC videos during the collapse of that day. When I watch the videos ( so many times ) this is what I observe when looking at the News videos.
Do you agree you see the same thing, if not what is it you see?

Once the supports were removed there was nothing holding the perimeter walls up, so of course they collaapsed.

Temperature and Strength of Metals
Influence of temperature on the strength of metals
Some common types of steel lose 10% of their strength at 450 C (840 F), and 40% at 550 C (1022 F). At temperatures above 800 C ( 1475 F), it has lost 90% of its strength.
Other types of steel are made to stand higher temperatures before losing 10% of their strength, but they are much more expensive (and are weaker at room temperature).
And there are types which actually get stronger, up to 450 F (but then get a lot weaker at higher temperatures.

What I see is too much energy being blasted out, my opinion is I am certain the only thing that can explain this is some kind of demolition.

That was compressed air and the compressed air had nothing to do with explosives, which is proven by the fact that the interior of a building consist mostly of air.
Explosive events were visible before many floors had collapsed...

Gambino asked Gouhliani, an attorney, if he had any solution to the problem
of the now idle WTC project.
Gouhliani came up with a solution. The mob would muscle the building
inspectors while Gouhliani and his college educated thugs would lobby the
courts to get the NYC building codes changed allowing the substandard steel
to pass inspection and thus prevent the steel contractor from having to
replace the steel used in the building with the proper product.
That is what transpired.
The NYC building inspectors and their families were terrorized and
threatened by the filthy Degos of Mafia and Gouhliani got the codes changed
in a hurry to allow the steel to pass muster.
The WTC tower's construction began again immediately afterward and Rudy "The
Rat" was the hero of the day along with Gambino and the rest of the Degos of
NYC.
