wtc7 collapse (rare video)

Je ziet toch dat het ongeveer 5 seconde duurt voordat het helemaal ingestort is. Terwijl volgens hem het 3.4 seconde duurt met free fall speed.

quote:

COMMENT: Appendix L to NIST’s June 2004 “Progress Report on the Federal Building and Fire Safety Investigation of the World Trade Center” contains NIST’s “Interim Report on WTC 7”. (See http://wtc.nist.gov/progress_report_june04/appendixl.pdf) On page L-26 of this interim report, NIST states that “Around 4:45 p.m., a photograph showed fires on Floors 7, 8, 9, and 11 near the middle of the north face; Floor 12 was burned out by this time.”

REASON FOR COMMENT: The contrast between NIST’s prior assertion that floor 12 was “burned out” by 4:45pm, and NIST’s current computer model, that shows a raging inferno at 5:00pm, could not be more apparent. This discrepancy calls into question the veracity of the Report.

SUGGESTED REVISION: This discrepancy must be acknowledged and explained in the Report. Furthermore, the photographic or other visual evidence NIST relied upon for its statement in Appendix L that floor 12 was burned out by 4:45pm must be included in the final version of its report.

quote:

COMMENT: To support NIST’s assertion that there was indeed fire present on floor 12 at 5:00pm, NIST has provided a single photograph from an “unknown source” (Figure 5-152, NCSTAR 1-9, p. 237), that was purportedly taken at around 5:00pm, and shows fire in the two windows that comprise the northwest corner. NIST contends that it has determined that this photograph was taken at approximately 5:00pm, with a margin of error of “at least 10 minutes,” using shadow analysis.

REASON FOR COMMENT: We find it unlikely that NIST could estimate the time the “unknown source” photograph in Figure 5-152 was taken with such accuracy.

SUGGESTED REVISION: NIST must explain how it was able to estimate the photograph’s time using shadow analysis to a margin of error even close to 10 minutes.

quote:

COMMENT: This comment relates to NIST’s assumptions regarding combustible fuel loading for the 11th and 12th floors. In NCSTAR 1-9, at p. 375 (para. 1, sent. 7-9) NIST states:

NIST assumed that the combustible mass of furniture was about the same in an office as in a cubicle. Since the loading of other combustibles was reported to have been high on the 11th and 12th floors (Chapter 3), NIST assumed that the total combustible mass in an office was double that of a cubicle. Thus, the average combustible fuel load on the 11th and 12th floors was estimated as 32kg/m2.

However, Chapter 3 tells us that, contrary to NIST’s assertions in Chapter 9, the loading of other combustibles was not reported to have been high on the 11th and 12th floors. On page 55 (para. 6, sent. 1) of NCSTAR 1-9, NIST reports that the U.S. Securities and Exchange Commission occupied the 11th and 12th floors and the north side of the 13th floor. On page 56 (para. 1, sent. 1) NIST further reports that American Express occupied the southwest sector of the 13th floor. On the same page, NIST reports that the “combustible load in the offices was described as high by interviewed American Express managers.” (NCSTAR 1-9, p. 56, para. 4, sent. 3)

REASON FOR COMMENT: Recall that American Express occupied only the southwest sector of the 13th floor. How, then can NIST credibly claim that the combustible load on the entirety of the 11th and 12 floors, both occupied solely by the SEC, was reported to have been high? Were American Express managers given regular access to the SEC offices, such that they would be qualified to comment on the combustible fuel load there? Moreover, are American Express managers qualified to give an opinion on the quantity of combustible fuel load as compared to offices in the Twin Towers?

SUGGESTED REVISION: Clearly American Express personnel are competent to provide information only on the state of the American Express offices, which were confined to the southwest sector of the 13th floor. NIST must provide real support for its assertion that the combustible load on the 11th and 12th floors was high in order to merit any increase in estimated average combustible fuel load on these floors. If it cannot provide such support, it should re-run its computer models with the lower combustible fuel load on these floors and report those results to the scientific community and the American public.

Combustible Fuel Loading on Floor 13

COMMENT: This comment is regarding NIST’s treatment of the combustible fuel load of the 13th floor. On page 375 of NCSTAR 1-9 (para. 1, sent. 8, 9) NIST states as follows: “The density of combustibles on the 13th floor was varied and not well known. The average value [for the 13th floor] was assumed to be the same as the 12th floor.” Here again, the only reported description of the combustible load on the 13th floor was from American Express managers, who were competent to comment only on the southwest sector of the 13th floor. In Chapter 3 of NCSTAR 1-9, page 57 (para. 2, sent. 2, 3) NIST reports that in the SEC occupied sections of northern perimeter of the 13th floor were “a hearing room and multiple testimony rooms facing it. There were additional testimony rooms on the northern portion of the east and west sides of the floor, and a storage room at the northwest corner.”

Importantly, NIST reports that the “testimony rooms were sparsely furnished, with just a table and a few chairs.” (NCSTAR 1-9, p. 57, para. 2, sent. 4) Furthermore, an examination of the schematic diagram of floor 13 (Figure 3-8, p. 57) reveals that the hearing room appears similar to a court room. Court rooms are also sparsely furnished, with a few tables and chairs. Finally, it is doubtful that there was any appreciable level of additional combustibles present in these testimony and hearing rooms.

REASON FOR COMMENT: NIST has apparently greatly overestimated the fuel loading on the 13th floor.

SUGGESTED REVISION: NIST must justify its use of the higher combustible fuel load on the 13th floor in Chapter 9 of the Report with more than just bare assertions. NIST clearly had more information available to it regarding the layout and make up of floor 13, as reported in Chapter 3, than it lets on in Chapter 9. This discrepancy must be reconciled.

Chapter 12: WTC Global Collapse Analysis

Section 12.5.3 – Collapse Time

COMMENT: This comment concerns NIST’s estimation of the time it took for the WTC 7 structure to fall. Specifically, this concerns NIST’s comparison to the actual descent time with a hypothetical free-fall time. (NCSTAR 1-9, p. 595; NCSTAR 1A, p. 40-41) Basically, NIST took two data points, and assumed a constant acceleration throughout the collapse. (Id.) The first data point was allegedly taken at the time the top of the parapet wall on the roofline of the north face began descending. The second data point was allegedly taken at the time the roofline was no longer visible in Camera 3. NIST claims that the time it takes for the building to fall this distance, 242 feet, is 5.4 seconds, plus or minus 0.1 seconds. No graphical or visual support is given for this time estimate.

REASON FOR COMMENT: Members of this group have conducted an independent analysis of the Camera 3 footage and come to an entirely different conclusion regarding the collapse time. Our analysis was done on a frame-by-frame basis using a frame rate of 29.97 frames per second. As shown in the figure below, our analysis concludes that it takes 3.87 seconds for the top of the roofline to descend out of view of Camera 3. This time matches almost exactly the free-fall time.

SUGGESTED REVISION: NIST must revise its Report to show the exact frames it used from Camera 3 in determining the time it took for the roofline to fall out of view. 5.4 seconds appears to be a gross overestimate. The frames we used in our collapse analysis are shown below (times “t + X seconds” reference the times given in NIST’s Appendix L, Table L-1) along with a graphical analysis of how we determined which frame represented the onset of global collapse:







Members of this group have used the Physics Toolkit computer software to plot Velocity vs. Collapse Time using discrete data points gathered during the entire collapse from the view NIST calls Camera 2. This plot is reproduced below and provides a much more detailed look at the dynamics of the WTC 7 collapse than is provided by NIST’s two-data-point analysis. Also included in the graph is a linear regression for approximately 2.6 seconds of the collapse that appears to have a constant acceleration. As can be seen, the slope (acceleration) during this portion of the collapse was approximately constant at about 9.8 m/s/s, or acceleration due to gravity with little to no resistance below. The r-squared value for this linear regression analysis was 0.9931 – a very good fit. This clearly demonstrates that NIST is being extremely misleading in reporting to the public that the structure did not descend at free-fall speed, especially given the implications of this documented feature of WTC 7’s destruction.

En dan durf je nog te beweren dat de stofwolk (van het verpulveren) al die schade aan de omringende gebouwen heeft veroorzaakt?

Want WTC torens zelf lagen in hun footprint en er was alleen stof over toch? Of waren het de plassen gesmolten staal die dat hebben gedaan? Of de hologrammen? Of toch de aliens met hun shark met friggin lasers on their heads?
