Some Misunderstandings Related to WTC Collapse Analysis

[Jeffrey Orling]

Tony,

Thanks again. One more question. How do you interpret the ejections or squibs seen well below the collapse levels of WTCs 1 & 2?

They are not squibs... wrong term... the are energetic puffs of directed air w/ floor contents (clgs etc) material forced out through the windows after following the path of least resistance which included vertical shafts, corridors, even ducts.

There is not coherent pattern to relate these to the sort of explosions INSIDE the core which would destroy columns... AND the colums SURVIVED as seen in the spire... the entire set of core columns in BOTH towers survived the floor collapse.. and fell from Euler buckling forces once striped of the bracing by the collapsing floor mass.

Short answer: Air over pressure caused by falling material INSIDE the tower's shafts.
