Two eyewitnesses reported a sequence of explosions coming from WTC 7 as it collapsed. Lack of recorded explosions in videos does not preclude the possibility of a controlled demolition.
I disagree. There is no real evidence of high explosives, including shockwaves. Yes, there were reports of loud sounds, but they weren't recorded on any devices.
You have no real evidence of CD. Still.
So.. those columns failed before they failed? Because that's essentially what you're saying. If those 8 floors of support had been removed then we would have seen that failure visibly before those floors hit the ground. Instead, we have a fully intact north face prior to the onset of the roofline's descent.
Your argument makes no sense. You obviously haven't read the engineering analysis. Your ignorance does not help your case.
Straw man. I never claimed 1 and 3 descended at gravity.
It's not a strawman to point out your error. You said the failure was 'immediate'
But then, you're still claiming 'The building is essentially in free fall after Stage 1,' so what's your point? Make up your mind.
besides, freefall acceleration was not a factor in the WTC tower collapses, so it is a powerful refutation of your claim that this is an indicator of CD.
To apply your own standard, we'd have to rule out CD for the towers.
But you won't apply the same standard, you'll dodge.
I've heard this argument before: it's a cop out. The total collapse time is irrelevant to the descent of the roofline because it is this measurement that tells us what the structure is doing. We can't measure the descent of the east penthouse because it becomes invisible.
What's a copout is pretending that the collapse didn't happen until about halfway thru where it actually began. That's equally stupid, dishonest and plain insulting if you wish to present it as such.
You might as well claim that the gestation of an egg is the time it takes to lay it, since there isn't a youtube video of the growth inside the chicken. That's how stupid your argument is.
What matters is the rate of failure of the main structural components.
You're getting warm, but no, you missed your opportunity by ignoring your own advice. Yes, the main structural components, some of which were directly below the E Penthouse, failed some 8 seconds before the entire roofline descended, at largely less than freefall speed.
btw, neither of the towers fell at freefall speed, only 64% or so that speed. So de facto, this renders your argument moot: freefall acceleration is not a reliable indicator of explosive controlled demolition, by your own standards.
If you won't apply your own standards to the various events, you are fooling yourself. Which you are, of course.
Can you correlate this claim with any other existing CD? I don't think you can, but you really ought to try before repeating the errors of other truthers like a robot.
Could you clarify this question?
Correlate your claim that, as part of a collapse which took some 14-18 seconds (verified by seismic records, btw), that this corresponds to any actual historical controlled demolition on record.
Pick any controlled demolition, do the measurements of acceleration, and get back to us with your analysis. If you really think you're a genius, go ahead and get the results published in a mainstream engineering journal.
Or failing that, send them to a qualified CD expert for commentary.
You'll do nothing of the sort, since your claims are fallacious and incompetent.
