At what point in the video does Courtney say the things you mentioned? It's 3.5 hours long.
Allgire mentioned a physical blockage from a faraday cage and shielding at the end of part 1 of the 911 project video, but because of the edit it's not clear what he was looking at or where. Just before, he was viewing some sort of operations room full of deadly serious military and civilian people pushing around pieces on a simulated battlefield. Outside was a huge circular antenna and his feeling was that it was somewhere in the DC area and that it had to do with the military or NSA. The NSA spy base in Sugar Grove, WV had two such AN/FRD-10 antennas, but the layout of the AN/FLR-9 antenna of Elmendorf, AFB outside of Anchorage, AK matches the drawing better. Another AN/FRD-10 is at the Center for Security Forces outside Chesapeake, VA and there are supposedly several smaller FRD-13 at other bases but I'm not sure which ones.
Heinz Pommer has a theory that aligns with what the viewers saw regarding the main destructive event, the vacuum cleaner sized cylinder underground where "metal turns to vapor".
In the 60's when people were trying to come up with more useful nuclear devices arose the idea of a slow-burn nuclear bomb that would work like a portable volcano if buried underground. It could be used to terraform mountains, create underground chambers, or demolish buildings by melting down their central columns. The months of volcanic heat, the radiation, and the subsequent bizarre "memorials" consisting of ugly pits coated with running water are entirely consistent with a small buried volcano-nuke and mitigation of the long term radiation at 'ground zero'. Blocks of explosives could have been used to destroy particular pieces of the building higher up.
With regard to the various ideas about nano thermite and dustification, I'm not so sure. The outer skin of the building was aluminum stuck directly on iron beams, a terrible idea from a corrosion perspective and likely to make flakes of iron oxide and aluminum naturally in a demolition. The concrete for the floors was supplied by the mafia, notorious for skimping on expensive things like cement binder leaving the floors prone to disintegrating without much effort at all. An entire parking garage in Boston made of mafia-crete pancaked to the ground when a crane bumped the roof. The twin towers were not only ugly and obsolete, but likely a disaster waiting to happen. I'm not surprised that rather than wait for disaster to happen naturally, unscrupulous people made it happen for maximum personal and political advantage.
Another interesting hit was at 1:22:00 in Farsight 911 part 2 where Allgire views the advanced preparations related to the collapse of the north tower. He sees a man in business attire with frameless glasses and a fancy standing desk, a member of PNAC, who advises the president, with a high pitched nasally Illinois accent, who is an icy cold evil operator. It was highly unusual to have a standing desk over 20 years ago, but this man had one:
Pause Farsight 911 p2 at 1:31:24 for the drawing of the evil mastermind planning the tower collapse.
Another interesting thing was that the viewers saw a missile hit the pentagon rather than a plane. Researchers already knew the flight data recorder info that was physically inconsistent with a real flight, but nobody could say what actually caused the destruction. Smith and Allgire both viewed a missile rather than a plane. Allgire viewed a submarine launched missile and heard the name 'Popeye' for no apparent reason. Only one country does actually name its submarine launched cruise missiles Popeye. One day after the aforementioned owner of a custom standing desk announced that $2.4 trillion of pentagon expenditures could not be accounted for, a Popeye-like miissile apparently killed off the auditing staff while the man hid on the opposite side of the Pentagon. He then went out and helped for an hour picking up wreckage despite being Secretary of Defense.
The 911 plot was probably not cooked up by Larry Silverstein and Frank Loewy, they just had a part to play and info was doled out to them on a need to know basis. It seems to me that this operation was big enough that it might have required the 'fortification' of the 2000 presidential election to guarantee that the right people would be in the right places. That's way beyond the reach of a couple real estate developers into international organized crime territory.
Who would be able to block remote viewers from seeing an obviously human plot to achieve evil goals here on Earth? Even the best viewers are not good enough to be a threat to a Dr. Evil. It could have just been an effed-up target. Making a good unbiased target seems to be kind of tricky.
