Regarding AE9/11'truth's freefall mistake:
ae911truth.info/wordpress/topten/faster-than-gravity/
The free fall saga is one of the more amusing trips into the world of AE911Truth. This mistake has gone through several incarnations, but each is just as wild as the next.
The first was in the original presentation. In this version, we are told that 7 World Trade fell in 6.5 seconds. The group, however, had only counted the time that the 47-floor building was visible above the skyline of other tall buildings surrounding Building 7, about 18 floors worth. When the roofline disappears, it has 29 more floors to go.
Keep this in mind through all of the rest – the 6.5 second count is the length of time it takes the 47-floor Building 7 to fall 18 floors, not its entire length.
In the second version, AE911Truth removed the timing but added a chart showing a constant acceleration of the building. All well and good — gravity is the constant accelerator and that’s to be expected. Yet the group’s graph clearly showed that the acceleration was 9.1 m/s-squared. On this planet, gravity accelerates at 9.8 m/s-squared. That means the building’s structure was actually giving a fair amount of resistance to the acceleration by gravity – that is, the building was collapsing at a rate slower than gravity.
In version 3, the group added the same erroneous 6.5 second timing back and kept the mistaken constant of gravity chart. Two silly mistakes on the same slide!
The group kept this slide for version 4, but version 5 added a whole new level of error. The same slide is present (now labeled “near” freefall), but it’s preceded by an interesting little video. Someone had plotted out the corner of 7 World Trade as it fell. The results appeared to show that WTC 7 fell unresisted at a speed of 10 m/s-squared, just a hair faster than gravity!
In other words, the group claims that the building fell at the rate of free fall acceleration, then says the building fell slower than free fall, having just demonstrated that the building fell faster than free fall speed (it is to be supposed, with New World Order building-collapse-accelerating rockets).
The most recent version continues this trend. The 6.5 second measurement is still implied to be the entire time of collapse, the first graph still claims 9.1 m/s-squared, but now a video from David Chandler claims that the building is falling at an average rate of 10.27 m/s-squared. Faster and faster this building keeps falling as the videos travel through time!
To his credit, Chandler mentions that 9.8 m/s-squared is “within the margin of error of this estimate,” quoted as 0.6 m/s-squared. However, I would suggest to him that the types of claims he wishes to make need a much lower margin of error that he’s currently capable of performing. Somewhere in a range of 1.2 m/s-squared is a lot of room for error here!
