Some Misunderstandings Related to WTC Collapse Analysis

[Tony Szamboti]

Your thinking regarding the structure below the 98th floor where initiation began is flawed. If that structure gave way first then the collapse would not have initiated at the 98th floor. I'll give you a reason the collapse started at the 98th floor. It was because it was the closest place to the impact where there was no damage and charges would not have been displaced. Even after the initiation the first floors to collapse where the 99th, 100th, and 101st floors. This is verifiable on video. Now why would four stories above the impact damage actually be the first to collapse?

I was suggesting the 95th floor right in the middle of the damage area. How about my suggestion that the collapse initiated at the impact zone because the core there was heavily damaged? Verified? What I see is the antenna giving way just before the whole top section plunges. It gave way because the impact zone inner core weakened to the point of failure due to crash damage and heat stress. The perimeter skirt quickly pulled inward causing the outer frame to displace and decouple off the outer frame below it. If the collapse started on the 98th floor it was because that was the last place where an intact core remained causing it to plunge as one solid unit into the wrecked core below it that finally gave out.

Where are the dust jet plumes for your 98th floor charges if it happened that way?

The plumes come out of the 98th floor very evenly, indicating it is the 98th floor failing, not the damaged area below.

NIST also determined the failure initiated at the 98th floor and their analysis here matches those of others and is not in dispute.
