Allow me to propose a theory that is far, far more plausible than the one you've proposed. Feel free to explore it: it comes with a Creative Commons license.
Okay, we know the U.S. has planes that are stealthy to radar, right? Suppose those planes can fly high enough to also be virtually invisible to the naked eye (they probably can). Then suppose we have a technology that allows them to leave no contrails (or chemtrails, for that matter).
Now, we also know that the U.S. has GPS-guided "bunker buster" bombs with fuses that can be programmed to sense voids. These bombs can go through layers of concrete/empty space/rock, etc. and then explode when they reach the predetermined void, such as Osama bin Laden's subterranean dialysis room. See where I'm goin' with this?
Suppose we have the technology to make those bunker busters invisible to radar and to the naked eye and recording devices, in daylight.
Problem solved. No invisible workers with invisible explosives did invisible construction at the WTC. No airliner pilots or R/C operators had to strike the exact floors where explosives were hidden. Just this: a spotter called the location of the fires to the stealth pilots, who programmed the bomb fuses to explode on those floors, and dropped their bombs right "down the pipes." A special explosive would have to be used, but that's a minor point. Or perhaps the bombs had some king of high-tech
bolas inside that wrapped around the columns and torqued them apart.
That's my theory, and I can't for the life of me figure out why a commission isn't investigating it. Can you?
