Quote from Grob109:
Think carefully.
Was there an impact?
Yes.
Quote from Grob109:
Did the towers survive?
Tautological and inadmissible for post postmortem consideration.
Science doesn't start with a forgone conclusion and fit facts around that to develop a 'working theory'.
Thankfully, WTC remains were quickly recycled before any meaningful forensic analysis could be completed.
Just like the OKC bombing.
But 'everyone knows' what happened. So this debate is really academic, right?
Quote from Grob109:
The rules and standards were met for planes impacting buildings, etc.
There is a key distinction you're missing.
The Towers were designed to not only withstand the impact. But SURVIVE it.
Thats why the WTC engineers and architects are on record after 911, flabbergasted the Towers collapsed.
There is no getting around this point.
Quote from Grob109:
The rules and standards did not work for many buildings that day with regard to *other considerations*.
In order for this to be true, you'd have to assume the WTC engineers forgot to account for fire damage caused by the FULLY LOADED jetliners they originally designed the Towers to withstand.
Patently absurd.
And their own testimony proves it.
Quote from Grob109:
You will find how much energy was involved at some point. Look into how long it was stored on the site after the impact.
The answer: not long.
If you want to get serious, refer to the WTC Collapse report performed by the NIST.
In it, they cite initial fire temps were 1000C. After the first 20 mins, they were no hotter than 500C.
At 500C, highgrade structural steel losses less than 35% of its strength.
Further, in NISTs' 'worst case' mockups, 500C truss temps were localized to no more than 15% of any one floor.
Think about that.
In order for the official truss theory to be true, a failure of 8 or 9 trusses (out of some 60 per floor) would lead to the cascading structural failure of the ENTIRE building.
A building that was explicitly overengineered around just such a contingency.
Sure.
Quote from Grob109:
Bronks is explaining a lot of stuff to those that can understand it.
I am glad to see you valiantly charge to his rescue. (I would too if the roles were reversed).
But he's debating strawmen and ignoring the best reconstructive data we have as to the WTC collapse.
Quote from Grob109:
The buildings simply fell apart after they were overwhelmed by the effects of the release of energy in concentrated focused places which were under heavily loaded conditions.
Thats a nice theory.
Unfortunately, the NIST investigative team couldn't replicate your theory using pragmatic failure tolerances and empirical data.
Instead they had to concoct a 'severe' collapse model - that admittedly ignored empirical fact and slashed assumed Tower strength - to generate the observable conclusion.
That is a huge red flag.
Quote from Grob109:
A cumulative effect occurred as the collapse was initiated. A gravitational impact of many many times the planes hitting the buildings.
This conveniently ignores the fact the WTC engineers built the Towers to survive such a collision in the first place.
