free fall

I keep seeing 'freefall' tossed around as evidence for controlled demolition, in threads where it would be off topic to discuss. Well, here is a thread where you can discuss it. I put it to any proponent of the Controlled Demolition theory for World Trade Center 7 (WTC7), that: There is no...

Why do "truthers" continue to make this claim? I've been re-reading the "draft" version of NCSTAR 1-9 and have seen several references to this portion of the collapse. Chapter 12 for instance has several (including graphs). Where did this "forced to admit" come from?

It is today quite simple to conclude how WTC7 was pulled down on 9/11! According NIST Final report of the WTC7 collapse http://wtc.nist.gov/NCSTAR1/PDF/NCSTAR%201A.pdf (20 November 2008) pp 47-48 one explanation is: "The probable collapse sequence that caused the global collapse of WTC 7 was...

Hi! I recently come across some youtube videos posted by "David Chandler". In it he uses footage of WTC7 and a software called "Physics Toolkit" to make the point that during a short intervall of the collapse, WTC7 was in fact in free fall, that NIST ignored this and that it is a sign of CD...

Perhaps this belongs in Sizzler’s recent thread. While there’s some overlap, I didn’t find exactly what I’m looking for (maybe I didn't look hard enough). Nor is my theme quite the same. Unlike Sizzler, I’ll state at the outset I’m not a truther by any stretch of the imagination (see...

Im wondering. We can simulate a zero gravity environment by letting an object to fall without being restrained by anything (eg, air). But what a subject is experiencing in that situation is precisely the effect of gravity!! So, why is this the same as, for example, being suspended in between...

Warning: I have a very limited internet access and therefore it is hard for me to seach for the exact official values, so the values below are just estimates and may be off by a significant amount. I would appreciate corrections. Thank you. 1) Did I miss something or are all the time...

If all the mass in the North Tower had fallen at free fall speed, there would have been zero energy left to do any other work. Estimate the amount of GPE actually available to do work, then subtract the amount needed to shred steel, then subtract the amount needed to pulverize all the concrete...

Maxim: If a suppossed explantion does not explain the event, it is not the truth. No explanation that does not explain the event can be the truth. So far no explanation in existence explains free fall and total pulverization of the towers appears to exist. Has anyone seen one?
