Hi Gamolon:
Terral,
You also didn't answer another question ...
Ask your
DoD Disinformation Handler (
How To Spot), Mr. Official Cover Story LIAR. I am here to present 'the' 911Truth for the benefit of the 'unbiased' third-party reader actually searching for 'the' 911Truth. You are here to convince these readers that
WTC-7 collapsed from building fires 
cuckoo

.
Start 'your'
Building Fires Did It Topic today and include 'all' of your evidence. Accept the "
Challenge" (
my Topic) or put a sock in it ...

PS. Anyone other than Gamolon interested in understanding how roofline movement plays a roll in calculating collapse times can start here:
Comments on the Draft Report NIST NCSTAR 1-9: Structural Fire Response and Probable Collapse Sequence of World Trade Center 7", issued by NIST August 21st, 2008.
Move over to the right-hand column and type the word "roofline' into the window and hit the 'Enter' key:
"Since NISTs estimate of the downward motion of Building 7 is based on a video taken at a distance of approximately 0.6 km, it would surely be impossible for NIST to detect a roofline movement of less than 50 cm. Thus there would be an uncertainty of about 0.5 seconds, (not 0.1 seconds!), in the determination of the time it took Building 7 to fall through the first few meters of its global collapse.
The 'Global Collapse' calculations focus on the 'roofline movement' and NOT anything going on with ANY other building component like the Penthouse.
"already noted one example from page 595: The time the roofline took to fall 18 stories was 5.4 s
. Another example is on page 277 from which we may deduce that WTC 7 fell 10 stories in 3.2 s. While it is true there is no a prior reason for the acceleration of a collapsing building to be constant except under the condition of free fall, evidence presented below shows that the acceleration of WTC 7 during global collapse was relatively constant over the first 4 seconds of motion."
Again, we are looking at 'The time the roofline took to fall 18 stories' having nothing to do with the Penthouse! Why? The reason is that we are making 'Global Collapse' calcuations that focus only on the WTC-7 'roofline' ...
Quite frankly, I do not care if Gamolon or any other Official Cover Story Stooge gets the 'Global Collapse' Calculations right. WTC-7 was still brought down using
Controlled Demolition. Period ...
