Why don't people want to know the truth about 9/11?

NIST failed to prove its theory

Why would NIST want to say Building 7 did not experience free fall? NIST’s lead technical investigator, Shyam Sunder, stated in the WTC 7 technical briefing that free fall could only happen when an object “has no structural components below it.”[ii] The only way for a building to have no structural components below it is to remove the lower structural components with an external force such as explosives. If the upper part of a building is crushing its lower structural components, in other words, doing the work of removing them, not all of its energy will be converted into motion and its descent will not be free fall.

A high school physics teacher named David Chandler objected to NIST’s initial claim, pointing out that, based on video footage of Building 7’s destruction, NIST’s claim contradicted “a publicly visible, easily measurable quantity.”[iii] Mr. Chandler wrote a comment to NIST, saying, “Acknowledgement of and accounting for an extended period of free fall in the collapse of WTC 7 must be a priority if NIST is to be taken seriously.”[iv]

Responding to the criticism, NIST in its final report issued in November 2008 did finally acknowledge that Building 7 descended at free fall. According to NIST, “This free fall drop continued for approximately 8 stories, or 32.0 meters (105 ft), the distance traveled between times t = 1.75 s and t = 4.0 s [a period of 2.25 seconds].”[v] However, NIST did not attempt to explain how Building 7’s free fall descent could have occurred.

Only explosives can instantaneously remove 8 stories allowing the upper structure to accelerate downwards in free fall. The absolute free fall of Building 7 over a period of 2.25 seconds is by itself overwhelming evidence that explosives were used to bring down the building.

The building didn't. Only a part of the facade. You are another one who ignores the fact that the inside of the building had collapsed several seconds before the facade that you can see ever moved.
