9/11 and the Science
of Controlled Demolitions
www.skeptic.com...
3WHAT ABOUT THE ALMOST FREE-FALL COLLAPSE OF THE TWIN TOWERS? The key is the “almost” modifier. If I told you I was making almost $100,000 and you found out I was making only $67,000, you’d say I was exaggerating. So stop exaggerating the collapse speed of the WTC Towers! The 80,000 tons of structural steel slowed down the collapses of the Twin Towers to about ⅔ (two-thirds) of free-fall.3 And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

That's great the owner said pull it. Abandon hope.
No professional Fire Department isn't going to surround drown and ground. Protect life and property. The property was a threat to nearby property. Surround And drown yes, but building 7 was the most perfect let it fall structure I and many have ever seen. To perfect.
Edit: never saw a high pressure hose system on 7 while it came down by which are un-manned. We know to suppress soot, airborne particles.

You
Never seen such a Perfect Free Fall with the the center going slightly first. falling in on itself.
In reality.
WTC 7 started with an internal collapse as indicated by the way the penthouse disappeared below the roof line. The internal collapse was from one side of the building, then worked its way to the other side.
A visible kink devolved in the building during the progressive collapse.
When the facade fell, it fell in three documented phases. The facade fell at free fall speed during the 2nd phase for 18 floors. then the facade slowed at the start of the third stage.
As a whole, WTC 7 fell slower than free fall.
The problem with your argument is it is a fantasy. The video evidence does not support your assertions:

SUMMARY OF EARLY WTC7 MOVEMENT
As was shown in section 2.5, features of the initial failure sequence can be understood as a rapid succession of 7 identifiable events occurring in the following order:
1) Movement Detected from 2 Minutes before Collapse
2) Increase of rocking 6 seconds before visible collapse
3) Ejections and overpressurizations
4) Collapse of the East Penthouse
5) Collective core failure
6) Perimeter response
7) Acceleration downward
CONCLUSIONS ON WTC7
The simulation was set up to fail. Even though the simulation bears almost no resemblance to the collapsed as documented, it is passively accepted as convincing by many.
It was gamed to collapse, and the collapse as simulated shows no key geometric features such as the collective core failure or flexure of the perimeter.
The issue of collective core failure leading to perimeter flexure and an extremely well-ordered collapse is not addressed at all. Instead, the public is asked to accept the simulated model even though it lacks an detail of the key geometric global features clearly visible in the collapse including:
1) Collective core dropping
2) Perimeter flexure as a response to the core falling
3) Building movement detectable from about 90 seconds before visible movement
COMPARISON OF NIST DESCRIPTION OF EARLY MOVEMENT OF WTC7 WITH THE ACTUAL VISUAL RECORD
1) Movement Detected from 2 Minutes before Collapse
Was never noticed by the NIST
2) Increase of rocking 6 seconds before visible collapse
This movement was measured by the NIST yet there is no explanation for it within their computer simulations of the collapse.
3) Collective core failure
Not noted or modeled in the NIST report
4) Perimeter response
Not noted in the NIST report. The Core-perimeteer action that is such an important feature in the early collapse process is not noted in the NIST report
5) Acceleration downward
Was measured incorrectly within the reports. The core-perimeter interaction was not understood and there were multiple problems with the NIST camera #3 tracking as listed earlier.

9/11 conspiracy theories have become social phenomena, despite lack of support from expert scientists, engineers, and historians.[313]

Can you cite a source WTC 7 fires were actively being fought

By the why, the opening post was “WTC 7 could not collapsed from fire, but WTC 5 had partial collapse from fire?”
Based on the fire related failures of WTC 5, how could anyone rule out fire related failure of WTC 7?
Per Wiki.5 World Trade Center (5 WTC) was originally a steel-framed nine-story low-rise office building built in 1970–72 at New York City's World Trade Center. The building was designed by Minoru Yamasaki and Emery Roth & Sons. The structure was 118 ft (36 m) tall and had a black exterior. It suffered severe damage and partial collapse on its upper floors as a result of the September 11 attacks in 2001. The remaining structure was demolished by the Port Authority in December 2001, making way for reconstruction. The building was L-shaped and occupied the northeast corner of the World Trade Center site. Overall dimensions were 330 by 420 feet (100 by 130 m), with an average area of 120,000 square feet (11,000 m2) per floor.
Are you now saying Epstein didn't say pull it for 7 and not collapse? 7 was built behind 5
Original building (1987–2001)
So let's see here; WTC 7 was demo'd,
