Really? Maybe you should watch the videos again. Not only do you see the penthouse collapse down into the building, but when the building collapses, dust comes up OUT of the top of the building. The only way it can do that is if the middle is pretty much gone.
Pretty much gone huh? Is that an engineering term? And you've drawn the conclusion that WTC 7 is an empty shell because you saw dust come up? Could that not perhaps be smoke? The building is on fire, isn't it?
There is another structure on the roof besides the east penthouse. Since this structure doesn't disappear until collapse begins, you are wrong: the roof is intact therefore the "middle" isn't "pretty much gone".
OK, so all columns had explosives wired up to them to explode them at the same time. The NIST determined that the minimum amount of explosives needed to break column 79 would have been the same as a gun shot right next to you a half a mile away from the explosive going off in an urban setting. So imagine how loud the explosion would be with ALL the columns being blown at one time? Yet what do we hear? Barely the collapse. How is THAT possible? You can't even claim thermate or thermite as they don't have the timing to make everything go at once even if you COULD get thermate or thermite to cut sideways.
Where are videos taken from? What kind of audio equipment did they use? Fire fighters moved people away from the building and said it was blowing up. There are eyewitnesses who were very close to it as it collapsed and said they heard sequential explosions.
Then you have to explain how none of the columns showed signs of being cut by explosives. Or how there were no blasting caps. Or how they managed to wire all the columns without a single person in the building noticing. Or how they kept the explosives from cooking off in the fires that burned for over six hours.
Can you prove there were no blasting caps? No. Can you prove none of the columns showed signs of being cut? No. Perhaps you can create a charge that can withstand an office fire without detonating. Or perhaps the
massive explosions we've heard on video coming from WTC 7 are in fact charges going off because of fire. But you've probably already thought of that, cause you're sharp.
More wisdom from the truthtard who isn't an engineer or anything other than a truthtard pulling shit out of his ass.

A shame none of your made up shit is worth a damn.
Again, this post contains no argument, nothing refuting my points. The column failures would had to have occurred on the same horizontal axis concomitantly. That's how such a demolition works.
Is the above post what you consider to be your wisdom that "makes truthtards cry" as you claim? If so, that's just sad. I know in your heart you think you're just killing it, but in reality you're just making an ass of yourself and hindering your own evolution as a person. I wish you the best of luck.
