How to lose 6 years time?

A few day ago i have considered why the <a href=”https://911rareview.wordpress.com/2013/07/14/fabulous-study-for-911truth-moment-transfer-by-gordon-ross/”>Gordon Ross theory is wrong to calculate the velocity of natural collapse of World Trade Center 1-2</a> when he mix anelastic hypothesis with elastoplastic hypothesis.

Now we can move from theory to practice.
Architect and Engineer for 911 Truth, founded by Richard Gage, from 2006 has always professed that:
1) a natural pancake collapse with more floor that impact with other floor lose more velocity into impacts and require more time to collapse then a free fall (Gordon Ross PDF to demonstrate this idea)
2) the WTC complex collapse with a free fall (more analysis videofor this idea)
3) the only way to have a free fall is that the below columns was destroyed by explosives like thermite.
(N.B.-other error:confute theory 1 dont make theory 2 exact; thermite does not have the characteristics of an explosive)

Ok, but in addition to theoretical errors, what we have in pratice?
In pratice time collapse show that dont is a free fall…

WTC1

WTC2

Melted con-fusion

Steven Jones joung, the physics that confusing molten steel with burned concrete, similar to Russel Crowe, the crazy mathematician on  “A beautiful mind”, at a conference on “Cold Fusion”.
