Building 7

World Trade Centre Build 7 (WTC 7) also known as “The Solomon’s Building” aka Building 7 was the third building to be destroyed on September 11th, 2001. It was a 47 story high steel frame building. The most salient question is; what caused Building 7 to fall at [1] freefall speeds for 8 stores? The building was not hit by any aeroplanes and there were no large raging fires. But yet it fell, fast and symmetrically into its own footprint. a few but limited fires.

Watch the 8 floors of free fall that starts off Building 7’s destruction:

 

Do the fires in the clip below look like they are endangering Building 7?

 

Did the fires you have just seen, cause 8 floors of free fall and the total destruction of Building 7, or not? That is the question, how can you find the answer?

First, what is freefall?

  • It’s not a speed, it’s an acceleration, an object getting fast and faster.
  • Free fall can only be obtained if there is nothing below a dropped object to slow it down.
  • More technically, it’s gravitational acceleration at 9.81 meters squared.

What then was holding Building 7 up?

Building 7 Typical floor plan

 

  • An exoskeleton of 57 steel columns.
  • Plus 22 steel columns for internal concrete clad lift shaft and fire escape stairwells.
  • In all a total of 79 steel columns plus concrete.

 

With reference to the above, the refined question being asked is?

What could simultaneous and symmetrical cause the removal of 57 external steel columns and 22 internal columns for lift shafts and fireproof stairwells?

There are two competing theories:

  1. Fire causing collapse.
  2. Demolition explosives causing collapse.

Q.
How can you evaluate these theories?

A.
   By looking at the extent of damage to steel framed buildings after known fires.
   By looking at examples of successful and failed demolitions using explosives

 

A Look at building fires:

A Look at demolitions:

Some common demolition traits are:

  • Sudden onset
  • Symmetrical fall for a number of floors
  • Freefall speeds for a number of floors
  • Pulverisation of concrete and other materials
  • Thick dust clouds
  • Horizontal ejections

 

Remember the Build 7 destruction shows 8 floors of freefall (i.e. the gap on the left).

Red Road Flats, 2015 Glasgow. Look for the aprox 5 floors exploded on each tower block.

Conclusion:

Where is the integrity of the news reporters, engineers, architects… who know that there are glaring flaws in the NIST report into the collapse of Building 7, but fail to point them out?

Are those that promote the “conspiracy theory” meme i.e. conflating unrelated events together themselves guilty of perverting the course of justice by preventing open debate and analysis? Do you know someone who does this? If so, challenge them. Show them the evidence and given them a chance to stop protecting murderers.
