I didn't set the goal posts, thedman. NIST defined them in its report. I'm just trying to make sense out of the conflicting reports about the
stability of WTC 7.
So what is the problem? The fire ground commander knows that WTC 7 is
badly damaged - he orders a surveyor transit set up and locked on
fixed location on the building.
I don't have a problem with this, if it happened. What I have a problem with is that as far as I can tell, this is not mentioned in the NIST report.
Why not? I could be wrong. Please, prove me wrong. I'd like to see where this has been officially reported.
The firemen discovered that the building was starting to move or creep. This tells them that the structure is unsound and not to put any men
inside.
Please post a link to these findings. Surely, if the firefighters made such a discovery, then it can be proven using facts? How much did the
building move? Over what time frame did the building move?
Once the building was discovered to being moving the fireground commanders ordered a collapse zone around WTC 7 and the area cleared.
The surveyor transit is used to determine if, where and by how much building is shifting.
How qualified are firefighters to judge the severity of damage to a building? Firefighters are
not structural engineers. Remember that the
firefighters determined that it was safe to enter WTC 2 to attempt rescue operations, right? We didn't see a collapse zone placed around WTC 2, did
we? That proves how uninformed the firefighters
opinions were, on that morning.
Don't get me wrong, I don't blame the firefighters for creating a collapse zone around WTC 7. After seeing two supposedly solid towers collapse on
them, killing lots of their own, I can see why none of the other firefighters would want to confidently enter WTC 7. In hindsight, it was a decision
that probably saved many more lives.
Guess what - you will not see the building move because up until the
moment of collapse the movement is fairly small. Offten only matter of
inches as building begins to move from the stress...
Again, I'll repeat my point above. Please post a verifiable link to the facts about the alleged transit. Please post the data from the transit that
proves WTC 7 did move, by how much and the time duration. Failure to do so is relying upon
opinions and not facts.
Why didn't NIST mention that WTC 7 moved during the afternoon? You think that would have been a critical piece of information to include in the
report about the collapse. Instead, NIST stated that WTC 7 suffered superficial damage and withstood the debris impact.
How can a building, that is supposedly leaning and bulging collapse, suddenly and symmetrically? Did you read the firefighter quotes at the end of
MacQueen's article that I linked to? Many firefighters were completely surprised by the way in which WTC 7 collapsed. Maybe they took a different
building collapse class than the one you took?
