*sigh* indeed. These issues have been discussed ad nauseum, I agree, but only because those who disagree with the reality of inevitable global collapse keep hand waving away the reasons that it was inevitable after initiation.
Yes, you and others have stated that they had to fall in order to equivalent to "a new Pearl Harbor," but that doesn't change the simple physics which prove that they had to fall just because they were hit by these aircraft at extremely high velocity in the first place. Yes they had to fall because nothing would have prevented it after the planes hit them as hard as they did. It took time, but that is only an indication of the fantastic design of the structural engineers who built them in the first place.
Yes the intensive discussion of this event only followed the actual collapses and that is because the structural engineers hadn't really considered the full impact of intentional terrorist attack when the buildings were originally designed and built back in 1968 and 1969. Yes they considered the possibility of an accidental crash of a 707, lost in fog for example, but not a targeted and intentional attack at maximum velocity. Had these aircraft impacted the towers as an accident at a lower velocity, the towers may well have survived as predicted by the non-terrorist considering engineers of the late 60s, but that isn't the reality of what occurred. I'm sure that the creators of my toaster oven didn't design it to withstand the angry application of my sledgehammer back in 1998 either, but the damn thing stopped working when I was craving crispy re-heated pizza and it was going down no matter what after I ate the limp microwave version.
Yes they certainly did, and most likely the only consideration they had at the time was one of an accident. Or do you reasonably think that they envisioned a terrorist attack of radicals crashing a plane into the towers intentionally at high velocity back in 1968 and 1969? Go look up when exactly intelligence agencies first communicated this as a potential threat to the government and see if it was before or after 1970.
Who can say for sure? I'd say probably not. The global collapses were without precedent, no doubt. As they say, there's a first time for everything.
Q24 has quoted bin Laden as indicating that the actual results of the attack were far beyond his highest hopes and expectations... and yet Q24 still holds the position that bin Laden played virtually no role in the planning and/or organizing of the attacks... really? Why on earth would he have hopes and expectations for something that he had virtually no role in implementing? Hrmmm...
My oh my how the claims and positions of 9/11 Truth adherents come back to bite them in the ass...
