# DID THE TOWERS COLLAPSE AT FREE FALL?

**DID THE TOWERS AND BUILDING 7 COLLAPSE AT FREE FALL**

Before we determine if the Towers and Building 7 collapsed at Free Fall. First it’s important to learn what free fall acceleration is.

**WHAT IS FREE FALL?**

What is Free Fall Acceleration?

“The Acceleration of Gravity. It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s (32.2 f/s/s), downward (on Earth).”

Work Done by Gravity Against Inertia and Air Resistance

http://www.school-for-champions.com/science/gravity_work_by_gravity.htm

“When an object is falling freely, the force of gravity is doing work against the resistance from inertia and the air resistance or drag on the object.”

What this means in layman’s terms is that an object can only reach free fall acceleration from gravity alone with NO resistance from Air or Inertia.

——————-

From experimentation, it has been discovered that, near the surface of the Earth, Earth’s gravity will produce a downward acceleration of 32.2 feet per second per second. (9.81 meters per second per second). What that means is that an object:

After falling one second, will be falling at 32.2 ft/sec.

After the 2nd second, it will be falling at 64.4 ft/sec.

After the 3rd second, it will be falling at 96.5 ft/sec.

After the 4th second, it will be falling at 128.7 ft/sec.

After the 5th second, it will be falling at 160.9 ft/sec.

After the 6th second, it will be travelling at 193.0 ft/sec.

After the 7th second, it will be travelling at 225.2 ft/sec.

After the 8th second, it will be travelling at 257.4 ft/sec.

After the 9th second, it will be travelling at 289.6 ft/sec.

After the 10th second, it will be travelling at 321.7 ft/sec.

Note: The velocity is achieved without any aero-dynamical resistance (vacuum). The air resistance will be significant for higher velocities or for object with large surface area to mass ratio – feathers or similar.

——————–

To give you an example of Free Fall Acceleration, when Felix Baumgartner made his record jump in 2012, he was timed at 4 minutes and 20 seconds in free fall. Before Felix Baumgartner pulled his parachute, he was travelling at 843.6 mph (1237.28 ft/sec).

9/11 EXPERIMENTS

https://kendoc911.wordpress.com/911-info/911-experiments/

On 9/11 we were told that the block on the left fell through the path of greatest resistance at nearly the same rate it would have taken to fall through air. Not only is this physically impossible but it also violates Newtons laws of motion. Objects cannot fall through the path of most resistance at near free fall speeds.

This would have been a great speech if William Veale only said “Near Free fall”.

===============================

**DID THE TOWERS COLLAPSE AT FREE FALL SPEED?**

It’s very important to state that the Towers did NOT collapse at “Free Fall” but they did collapse at NEAR free fall acceleration. NIST claims the towers collapsed in 9 and 11 seconds respectively but from video footage, it appears the collapses took between 11-14 seconds. Let’s look closer.

Free fall (time and velocity) Calculator (WITH NO AIR RESISTANCE)

http://keisan.casio.com/exec/system/1224852055

First lets find the HEIGHT (h) of the North (WTC 1) and South (WTC 2) Towers.

*********TWIN TOWERS (WTC 1 & 2)**********

Location: New York City

Status: Destroyed September 11, 2001

WTC 1: 1,368 ft (417.0 m) (with antenna 1,727 ft (526.3 m)

WTC 2: 1,362 ft (415.0 m)

Floor count: 110 floors

http://en.wikipedia.org/wiki/World_Trade_Center

—————

So now go back to the Calculator and enter 1,727 ft (h of North Tower w/antenna) in the free fall distance height box. Then hit execute.

The results are 10.361158327745 seconds.

Now let’s enter 1362 ft (h of the South Tower) in the free fall distance height box. Then hit execute again.

The results are 9.2013318746445 seconds.

(Note: The Acceleration of Gravity remains constant at 9.80665 m/s2)

————-

According to the Official Story:

“NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2.”

————

“The measurements have indicated that Tower one collapsed in about 11 seconds and Tower two collapsed in about 9 seconds…..this is essentially the rate at which free fall would happen.” – Shyam Sunder NIST

http://www.youtube.com/watch?v=5jmOOIBO9UM

———

“11. How could the WTC towers collapse in only 11 seconds (WTC 1) and 9 seconds (WTC 2)—speeds that approximate that of a ball dropped from similar height in a vacuum (with no air resistance)?

“…to the tremendous energy released by the falling building mass, the building section above came down essentially in free fall, as seen in videos.”

World Trade Center Physics – Why Constant Acceleration Disproves Progressive Collapse

http://hem.bredband.net/infernus/911/World-Trade-Center-Physics-2016.pdf

————-

**CONCLUSION:**

According to NIST’s figures:

The North Tower collapsed in 11 Seconds and Free Fall would have been 10.36 Seconds.

The South Tower collapsed in 9 Seconds and Free Fall would have been 9.2 Seconds.

Both Towers collapsed at the rate of near free fall.

==================================

**DID WTC 7 COLLAPSE AT FREE FALL SPEED?**

WTC 7 was 610 feet tall and collapsed in under 7 seconds at 5:20pm in the afternoon on September 11th, 2001. Not only did WTC 7 collapse in under 7 seconds, NIST themselves admitted that it collapsed for 2.25 seconds at free fall acceleration for over 100 feet.

First let’s find the HEIGHT (h) of WTC 7

***** WTC 7*****

The original 7 World Trade Center was a 47-story building, standing 610 feet (186 m) tall. It collapsed in its own foot print on September 11th at 5:20pm in 6.5 Seconds.

http://en.wikipedia.org/wiki/WTC_7

———

Now go back to the Calculator and enter 610 ft (h of WTC 7) in the free fall distance height box. Then hit the execute button.

The results are 6.1578209789918 seconds.

(Note: The Acceleration of Gravity remains constant at 9.80665 m/s2)

———

According to the Official Story:

NIST states that WTC 7 collapsed in under 7 seconds and was primarily due to fires.

“7 seconds for the north wall to come down.”

WTC7: NIST Finally Admits Freefall (Part I)

http://www.youtube.com/watch?v=eDvNS9iMjzA

“The collapse of WTC 7 was primarily due to fires.” – Shyam Sunder

**CONCLUSION**

WTC 7 collapsed at free fall acceleration for 2.25 seconds of its 7 second collapse. Basically, WTC 7 collapsed at near free fall. NIST’s own admission.

**NOT ALL CONTROLLED DEMOLITIONS COME DOWN AT “FREE FALL”**

People will argue that the buildings did not come down at “FREE FALL”. This is correct. The Towers fell at “NEAR” free fall speed. However, not all CD’s come down at free fall. Here are several examples of other Controlled Demolitions collapsing no where near the rate of free fall.

Collapse Rates of the WTC Consistent With Controlled Demolition

http://911debunkers.blogspot.ca/2010/07/collapse-rates-of-wtc-consistent-with.html

“In conclusion, the rate of fall of the Twin Towers appears to be consistent with the rate of fall for buildings brought down with controlled demolition. At the same time, their fall rates are inconsistent with the rate in which other steel framed buildings have fallen top to bottom from fire. So ask yourself, “what is more likely to have destroyed the buildings? Fire or explosives?” You decide.”

**EXAMPLES**

Ocean Tower Demolition – 31 stories (379 foot-9 inch tall) Roughly 1/3 the height of the Towers.

Ocean Tower – Controlled Demolition, Inc.

http://www.youtube.com/watch?v=SaBQ3AkRetI

Starts to collapse at 24 seconds, ends at 35 seconds. That’s 11 seconds for a 379 foot building to hit the ground. That’s well off free fall acceleration.

118 meters (387 Feet) tall. The collapse took about 7 seconds. Free fall would be 4.91 seconds.

**CONCLUSION**

It’s very important to state that the Towers did NOT collapse at “Free Fall” but they did collapse at NEAR free fall acceleration. Although, judging by other Controlled Demolitions I sourced in this note, not all CD’s come down at FREE FALL either.

Note: WTC 7 was 610 feet tall and it was gone in roughly 6.5 seconds. Free fall would have been 6.16 seconds.

“NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2.”
