I don't freakin know!

My guess is that is had to be fired from a satellite or maybe from one of the doomsday planes flying around at all 3 impact sites??
A thermobaric weapon was fired from a satellite or from one of the doomsday planes? What? Or are you talking about energy weapons now?
The point of the link I posted is that there is technology available and the thoery is plausible. Much more so that the government's theory.
Except your theory isn't plausible at all. If a thermobaric weapon were used on the WTC it would not have looked at all like what it did. Besides, you don't even know what "the government's theory" is, as you have obviously not read the NIST report. Therefore your opinion of its plausibility has about as much worth as my dog's.
If I knew the physics and implementation of secret weapon technology, I certainly would not be here speculating about it on a forum with you folks! We'll just have to keep an eye on Morgan Reynolds' court case.
Which will go nowhere, I assure you. Don't be pissed, or surprised, when it's tossed out of court as frivolous. The rest is just argumentum ad ignorantium. Here's a thought: why don't you go study the physics relating to the weapons system you're describing, or better yet (since you're obviously not a scientific type) why don't you ask a scientist from the relevant field if the scenario you're speculating about is feasible? Where do you think secret weapons programs come from?
Do you wanna explain how the majority of the jet fuel that (clearly) all burned up outside the building and subsequent office fire from the remaining fuel burned hot enough to weaken steel and specifically turn this spire into dust causing a universal collapse?
The jet fuel did not
clearly all burn up outside the building. A great deal of it spread throughout the impacted floors causing widespread fires. NIST estimates that most of the fuel burnt up within 10 minutes, but the mass of office contents continued to burn for almost two hours in the North Tower and almost an hour in the South Tower. Office fires are known to reach very high temperatures: up to 1800 degrees Fahrenheit, more than hot enough to significantly weaken the damaged steel core columns and the remaining perimeter columns that had not already been severed from the aircraft impacts, as well as the floor trusses connecting the floors to the perimeter and core columns. As a result the floor trusses of several floors were deformed, eventually pulling the perimeter columns inward towards the core. (This bowing of the perimeter columns can be seen in close-up pictures and videos of the towers focused near the impact zones minutes before the collapses.) Once buckled, the perimeter columns could no longer hold the loads they were bearing and redistributed them to the already weakened core columns. Thus the whole upper portion of the tower above the impact zone was being held up by a few core columns, far more than they were designed to hold, and global structural failure inevitably ensued. This initiated a more or less symmetrical collapse in the form of the "pancaking" effect: floor after floor being sequentially stacked onto the ever increasing falling mass of the upper portion of the building.
You would know all this had you read any of the NIST report.
The spire clearly turns to dust as it begins to fall.
No, it clearly doesn't turn to dust. You keep ignoring the better resolution video that clearly demonstrates this.
Here it is again. And it's not a "spire", it's the remainder of the core column structure.
Even if a plane did sever a few of the large beams of steel, what would cause the entire building support structure to fail simultaneously?
Already explained above.
You cannot deny the fact that the majority of mass that was The WTC was virtually pulverized in dust. A office fire caused this???
The majority of the matter in the towers was certainly not pulverized to dust. Where do you get that figure? And no, an office fire did not cause any of the pulverization. The collapse did, though.
There are quite a few structural engineers that admit the collapse they witnessed that day would not have been caused by the fires and impacts alone.
Name one.
