By your definition, there has never been a controlled demolition of any building.
And while were at it, I guess all those less than successful controlled demolitions were not controlled demolitions either."
interesting.TruthersLie said:"Prove it. Nice weasel words again... since no other building that size has ever been CD'ed it would be hard to show it... eh?
Though the CD's of the Landmark Tower and the J.L. Hudson implosions were confined to within their own footprints and didn't strike ANY buildings across the streets... amazing eh?"
Or do you now consider the building grounds surrounding its "architectural footprint" to be part of the footprint?

TruthersLie said:"while we are at it, I find it very interesting the countries of origins of those failed CD's. But we can look into them if you want...
But either way, the building didn't collapse into its own footprint. There was a small debris field, yup. Which then goes to the SO WHAT?
By collapsing and striking two adjacent buildings at over 180 degrees apart (rather asymmetrical don'tcha think?) it shows it wasn't a CD"
Countries of origin?
Sounds rather prejudicial to me.
But aside from your implied slur against other nationalities, you are dodging the key point here.
Not all controlled demolitions are perfect.
Sometimes they are less than perfect.
How does a less-than-perfect controlled demolition become a non-controlled demolition?
In that vein, whomever engineered the controlled demolition of WTC7 had much to gain from bringing it down as a less-than-perfect controlled demolition.
If anything, they did too good a job.
Miragememories said:"You are sure that it didn't end up across the street during the unsymmetrical, toppling southward collapse you subscribe to?"
Which means it is now inside of WTC7.TruthersLie said:"Not at all. We can see the eastern mechanical penthouse collapse. How could it possibly end up on the other side of the road? Oh it couldn't... But where did it go anyways? How can you misrepresent the building type, the collapse area and the collapse time? Oh yea.. I forgot and intellectual midget like you HAS to."
Are you pre-supposing that it collapsed to the ground before the completion of WTC7's global collapse?
Or is it not possible that late in the global collapse, when WTC7 was toppling to the south, the remains of the east penthouse were carried across the road?
Miragememories said:"Until you can prove the non-existence and/or the structural insignificance of the concrete used on every floor in the construction of WTC7, you are misrepresenting the truth."
Well let us see what the NIST had to say in NIST WTC7 FINAL.TruthersLie said:"you are the one making the claims, the burden of proof is on you. the NIST reports, FEMA and others list wtc7 as a long span steel framed building. There is NO concrete reinforcement... Feel free to look them up."
pg.6
"The floor slabs were reinforced concrete of varying thickness."
"on Floors 8 through 47, the concrete was 0.14 m (5.5 in.) thick."
pg.7
" The floor beams were connected to the concrete deck by shear studs, which caused the floor beams and concrete slab to act together, or compositely. This type of floor system is thus referred to as a composite floor. The floor beams were framed into (connected to) girders with a variety of types of shear connectors1, through which the floor beams transferred gravity loads from the floors to the girders. The girders also framed into the columns with a variety of types of shear connectors and transferred the gravity loads to the columns."
pg.38
"Temperature-dependent mechanical properties of steel (Appendix E) and concrete (NIST NCSTAR 1-6A) used in the construction of WTC 7."
pg.52
"...power to the fuel pumps, (b) could not be sustained long enough, or generated too little heat, to raise the temperatures of the steel and concrete structure to the point of significant loss of strength or stiffness..."
pg.55
"Thus, the details of the progression of horizontal failure and final global collapse were sensitive to the uncertainties in how the building materials (steel, concrete) and building systems and contents interacted, broke up, and disintegrated."
bolding is mine
Now you were saying?
