There would be no seismic record if joints were heated or hydraulics were used to remove the columns of the first eight to nine floors to collapse in WTC 1. Even small explosives used that high probably wouldn't produce a seismic record. After that the collapse could probably proceed on it's own as at that point the floors outside the core would collapse due to a quasi-static overload.
The problem is that in the early stages there needed to be a jolt and there isn't one. You can't take out the core without one. It really is that simple.
Tony, that's just silly. You're just fantasizing about this now - there is not a shred of evidence which supports the idea that the joints were artificially heated and that hydraulics were used.
What there is abundant evidence of, but you refuse to accept (for an emotional reason, not a logical one) is that the towers were hit by planes and then experienced large fires without any fire suppression, or proper insulation.
Your elaborate and fantastical ideas are utterly redundant and unnecessary to explain the events accurately. I admit the jolt idea is intriguing, but we have now explored that question honestly and thoroughly with you, and it does not fit with the evidence. Sorry.
WTC2 had a strong tilt, so there was no need for a jolt, so it is logical to accept it collapsed just from the fires. Your own criteria allow this. And if they allow one, they must allow the other as well, since the evidence is overwhelming that they experienced similar traumas.
It's your business if you want to wallow in this stuff until well past it's due date, (which was some time ago, frankly), but if you harbour further fantasies about swaying the engineering community over to your POV don't bother, it will never happen.
I commend your persistence, but you must know that your efforts are futile if you wish to find and prosecute any alleged perps in this vast and fantastic conspiracy you are erroneously pursuing.
That's a polite way of saying that I think you're a little nuts. But that's your problem, not mine. You really ought to listen to a very smart man like Ryan, it would do you some good, sir. Sincerely.
