prove there is a conspiracy when thousands of financial put-offs on not just the airlines, but the companies that had headquarters in the building instantly made thousands of people millions of dollars. Why put-offs even financially exist is mind boggling enough,
From NIST NCSTAR 1-3
5.1 THE RECOVERY OF WORLD TRADE CENTER STRUCTURAL STEEL
Beginning in October of 2001, nearly a year prior to the start of the National Institute of Standards and
Technology (NIST) Investigation, members of the Federal Emergency Management Agency (FEMA) –
American Society of Civil Engineers (ASCE) Building Performance Assessment Team (BPAT), members
of the Structural Engineers Association of New York (SEAoNY), and Professor A. Astaneh-Asl of the
University of California, Berkeley (with support from the National Science Foundation), began work to
identify and collect World Trade Center (WTC) structural steel from the various recovery yards where
debris, including the steel, was taken during the WTC site clean-up effort. Dr. J. Gross, a research
structural engineer at NIST and a member of the FEMA/ASCE Building Performance Study, was
involved in these early efforts.
There were four major sites where debris from the WTC buildings was shipped during the clean-up effort:
• Hugo Neu Schnitzer, Inc., Fresh Kills Landfill in Staten Island, New Jersey,
• Hugo Neu Schnitzer East, Inc., Claremont Terminal in Jersey City, New Jersey,
• Metal Management, Inc., in Newark, New Jersey, and
• Blanford and Co. in Keasbey, New Jersey.

I more than adequately answered you questing.
And you wrong about the distribution of floor weight. When the upper floors fall, releasing their stored potential energy beyond building design, the static floor below fails at its weakest point, the floor steel to column connections. A floor connections cannot magically resistance more strain than it can physically handle. What does Newton's law have to do with yield strength of floor connections?
are these ~6 floors suspended in mid air? do they have absolutely no support from the ~75 floors and basement floors beneath them?
The strength of the steel and thickness of the steel plates decreased with height because they were required to support lesser amounts of building mass on higher floors.
So if floor 79 had a load higher than it could withstand it would fail.
But then floor 78 would have the same (if not more) weight and it would fail.
And so on.

are you saying 220 floors of steel columns were recovered from the WTC site, and the majority of them were bent?
are you also saying that 30 floors fell on 6 floors? disregarding the fact that there are another ~75 floors of reinforced, thicker steel below them?
please, enlighten us with sources for your claims.
