The article makes several good points, but I think the case for a space-based microwave beam used to take down the WTC towers is better in terms of the overall evidence:
Here are the principal data that must be explained:(emphasis added)
1. The Twin Towers were destroyed faster than physics can explain (free fall speed "collapse")
2. The protective bathtub was not significantly damaged by the destruction of the Twin Towers
3. The rail lines, rail cars and tunnels had only light damage
4. The WTC mall survived well, witnessed by Warner Bros. Road Runner and friends
5. The seismic impact was minimal, far too small based on our comparison with the Kingdome controlled demolition
6. The Twin Towers were destroyed from the top down, not bottom up, unlike WTC7
7. The upper 80 percent, approximately, of each tower was turned into fine dust and did not crash to the earth
8. File cabinet with folder dividers survive
9. Office paper was densly spread throughout lower Manhattan, unburned, often along side burning cars.
10. Vertical round holes were cut into buildings 4, 5 and 6, plus a cylindrical arc into Bankers Trust and into Liberty street in front of Bankers Trust
11. All planes but top secret missions were ordered down until 10:31 a.m. (when only military flights were allowed to resume), after both towers were destroyed, and only two minutes after WTC 1 had been destroyed
12. Approximately 1,400 motor vehicles were towed away, toasted in strange ways during the destruction of the Twin Towers
13. The order and method of destruction of each tower minimized damage to the bathtub.
14. Twin Tower control without damaging neighboring buildings, in fact all seriously damaged or destroyed buildings had a WTC prefix, and no others.
15. The north wing of WTC 4 was left standing, neatly sliced from the main body which virtually disappeared
16. The WTC1 and WTC2 rubble pile was far too small to account for the mass, unlike that of WTC7
17. Eyewitness testimony about toasted cars, instant disappearance of people by "unexplained" waves, a plane turning into a mid-air fireball and electrical power cut off moments before WTC 2 destruction, the sound of explosions
18. The possibility that a technology exists. Since invention of the microwave for cooking in 1945 and laser beam in 1955*, commercial and military development of beam technology has proceeded apace, so use of high-energy beams are likely
What theories are available to explain these phenomena?
We can identify seven theories:
1. Natural causes such as earthquakes and hurricanes
2. Arson
3. The official theory of airplane impact, fires and weakened steel collapsing
4. Conventional demolition with explosives such as RDX, dynamite, etc.
5. Demolition via thermite or its variants
6. Fission or fusion nukes (and clean bombs)
7. Beam weapons
No one proposes that an earthquake destroyed the Twin Towers from the top down. The theory is contradicted by nearly all the data above. For example, no earthquake can toast cars in inexplicable patterns.
In fact, the data refute theories a to e –- natural, arson, official, conventional and thermite demolition -– in particular the intact bathtub, minimal seismic impact, and "dustification" prove nothing close to 1 million tons of material slammed down on the WTC foundation and its sub-basements. The debris stacks left where the Twin Towers once stood hardly covered the ground. The rescue dogs and workers did not climb up a tall pile but had to repel down to search for survivors. The arson and thermite theories fail to explain every data point, but all the unburned paper in particular refute any high-temperature base hypothesis.
The nuclear theory fails because an explosion powerful enough to turn most of each tower to dust would have seriously damaged the bathtub, probably flooded lower Manhattan, and spiked a high Richter reading. It violates a number of data points, including the observed top-down disintegration. And if a nuke were at the top, it could not progressively destroy lower floors and there were only a few steel beams tossed onto adjacent buildings and none above the 20th floor. Lots of aluminum cladding was tossed onto neighboring buildings’ roofs but no steel beams. How could a nuke be so selective? It could not. Nor can a nuke explain the toasted cars.
All the data are consistent with a beam weapon. Take the round holes in buildings 5 and 6. A high-energy weapon by definition could cut into buildings, destroy material and leave discreet boundaries in the buildings. We have know of no other explanation that has been offered for these peculiar holes. Similarly, some 1,400 cars were toasted in inexplicable patterns, and no alternative explanation to energy wave reflections has been offered. As Sherlock Holmes declared,
"When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth."
