Or people ignored an assertion that was non sensical.

There's nothing wrong with your "Tell me what is wrong..." except that you can't even prove that the collection of disassembled objects previously know as WTT, then falling from one of the World Trade Towers were or were not falling at "free fall speed."

Given the huge clouds of dust, you'd have to rely on radar or acoustic signatures. Then given the settling of the debris, you'd at best have an envelope of uncertainty around your imaginary concept of "free fall speed."

Next you'd have to conjecture that the resistance of the collapse somehow was outside of the bounds of that envelope of uncertainty. Being Tecshare, you'd like to determine that by PROCLAMATION BY TECSHARE.

It doesn't work that way. Show the math and the numbers if you want to be taken seriously.

How about the official 9/11 commission report?

"From 9:59 until 10:28 A.M.
At 9:58:59, the South Tower collapsed in ten seconds..."
P. 305 "THE 9/11 COMMISSION REPORT"

How tall was it?

"The North Tower rose 1,368 feet—1,730 feet with a large antenna—and the South Tower stood 1,362 feet high."

https://www.911memorial.org/learn/resources/world-trade-center-history


1362 feet in 10 seconds. This requires zero resistance to reach these speeds.

You've pulled that quote from a general description of the events, not even related to timing.
How do you figure "requires zero resistance"?

Here is the paragraph in full and in context.

...First responders assisted thousands of civilians in evacuating the towers, even as incident com- manders from responding agencies lacked knowledge of what other agencies and, in some cases, their own responders were doing.

From 9:59 until 10:28 A.M.
At 9:58:59, the South Tower collapsed in ten seconds, killing all civilians and emergency personnel inside, as well a number of individuals—both first responders and civilians—in the concourse, in the Marriott, and on neighboring streets.The building collapsed into itself, causing a ferocious windstorm and creating a massive debris cloud.The Marriott hotel suffered significant damage as a result of the collapse of the South Tower.


Regardless, why would you use the highest elevation to calculate the speed of fall? the collapse started from about the 80th floor. Seems you've improperly described the events in order to make a point.

From page 294.

At 9:03:11, the hijacked United Airlines Flight 175 hit 2 WTC (the South Tower) from the south, crashing through the 77th to 85th floors.

Assuming 12 feet per floor, 12*80 = 960 feet until the section above the crash zone hit the debris pile. And how long is your prized "free fall speed" for 960 feet?

Looks about 7.3 seconds. Looks like your theory is disproved, because initial presumptions were incorrect.
