WTC7: NIST Finally Admits Freefall (3-part video)

In its draft report, released in August 2008, NIST attempted to cover up evidence that WTC7 fell at freefall, but the coverup was transparent. In its final report, released in November 2008, NIST finally acknowledged freefall, but couched it in a bizarre framework that continues to deny its clear significance. Part I [of this video] chronicles NIST’s attempted obfuscation and eventual admission of freefall. Part II demonstrates that their replacement theory is based on fabricated evidence and is a continuation of the coverup. Part III will spell out the significance of NIST’s admission of freefall.

WTC7: NIST Finally Admits Freefall (Part I)

NIST has now officially accepted that WTC7 came down with the acceleration of gravity, but they still couch it as a phase in a 5.4 second interval they claim matches the 5.4 seconds required for their model to collapse 18 floors. The starting point of their 5.4 second interval is totally arbitrary. This new video highlights the August 26 technical briefing and allows Sunder and Gross to shoot holes in their own feet.

A previous analysis of the freefall acceleration of WTC 7was criticized (legitimately) for using a horizontal calibration measurement for analyzing purely vertical motion. Any distortion or stretching of the video could throw off the measurement. In this new video, the calibration utilizes NIST’s data for the heights of the roofline and the 29th floor to do a vertical calibration. The result is a measurement even closer to idealized freefall: 9.88 m/s^2.

Comment at YouTube: Some viewers have questioned the details of the measurements shown in this video. I have created a FAQ page to deal with these questions:

Since 2004, 911Truth.Org has educated the public about the suppressed realities of the September 11 attacks.

We worked with the 9/11 Families to pressure the Bush administration to convene an investigation into the deadliest attacks on US soil since Pearl Harbor. We attended many of the commission hearings and questioned commissioners and bird-dogged elected officials to get answers to the Unanswered Questions that remain so to this day.

We reported the contradictions, lies and omissions on the public record. 911Truth.Org staff have given hundreds of interviews on radio and mainstream network TV.

We cover a wide range of 9/11-related issues in publishing academic papers, original research, and opinion pieces.

We wish to thank our donors who have kept us on the web since 2004! We appreciate your continued support!

We continue to update the website to make the nearly 3000 articles easier to find, read and share. Thanks for visiting us!
