:shock: "Non-commital...like most physics"???!!
WTF?
Oh, so they don't use physics to build cities and launch satellites and perform medical operations and....
ding. I don't trust the judgement of people who don't place any confidence in laws of physics and can't even read citations of the same.
M'k. I'll drag the evidence over to this board. Hope it isn't too - wah! - "boring."

"Shortly after the core columns under the East Penthouse of WTC 7 collapsed, the rest of the building collapsed mostly into its footprint in about 7 seconds — near free-fall speed."

"Taken from the FEMA report, Fig. 5-26, this photographic evidence begs to question why WTC 7 imploded when WTC 6 and WTC 5 were closer to the Twin Towers and more heavily damaged by falling debris, yet, their structures remain."

"The official FEMA report states: "The collapse of WTC 7 had a small debris field as the facade was pulled downward, suggesting an internal failure and implosion...
Demolishing the building so that it collapses straight down into its own footprint requires such skill that only a handful of demolition companies in the world will attempt it." "
These office fires were not enough to heat a column weighing 15,000 pounds per floor to 1000° F.


East: about 2:30pm
[floors 11 and 12 - Arrows point to

North: about 3:00pm
[floors 7 and 12]

North: 4:48pm
[8 and 13 - fire on floor 12 had burned out in east end]
The NIST hypothesis offers NO explanation for the collapse of half the core columns.The sudden and complete destruction of World Trade Center 7 was not included in the 911 Commission Report.

The Case for Explosive Demolition of the WTC Towers

No steel framed high-rise building has ever collapsed due to fire - due to the high temperatures that would be required to weaken structural steel past it's critical safety margin - even though very large, very hot, and very long-lasting fires have ravaged many steel-structure high-rise buildings. These buildings are all in use today:
• Caracas, Venezuela, Oct, 2004, 56 story building,
burned for 17 hours over 26 floors
• Los Angeles, May 1988, 1st Interstate Bank, 62 stories,
burned for 3.5 hours over 5 floors
• Philadelphia, Feb, 1991, Meridian Plaza, 38 stories,
burned for 18 hours over 8 floors
• New York, Aug, 1970, New York Plaza, 50 stories,
burned for six hours

Previously molten metal was found "flowing like lava" by the FDNY in the basements of all 3 WTC High-rises. Hydrocarbon fires can burn at a maximum temperature of 1,800°F which is about 1,000° short of the beginning melting temperature of steel. Where did the molten metal come from? Why do FEMA and NIST deny its existence?

The 4- to 20-ton steel columns & beams were broken apart at bolted and welded connections and ejected laterally up to 500 feet.

The architectural drawings of the WTC North Tower have been leaked from an individual associated with the Silverstein-Weidlinger Report. They reveal that the large box columns of the core maintain their 30"x16" and 52"x22" dimensions at least up through the 66th floor. They also indicate that most of the core columns would be easily accessed from the elevator shafts in order to plant explosives. We know that the elevators were being modernized by Ace Elevator during the 9 months prior to 9/11.
This is the World Trade Center exploding.
This is an acknowledged explosion.
Can you tell the difference?

Which 20 story building will fall to the ground first? Until 9/11/01 most physicists would have agreed that the one that didn't have to crush though 100,000 tons of steel would fall first — at free-fall speed. On 9/11, the example on the left "collapsed" at virtually free-fall speed!
But this could only have been accomplished by removing the columns ahead of the fall — with explosives.
Numerous Squibs (mis-timed explosions) can be seen seen 20 to 40 floors ahead of the advancing "collapse". NIST claims that they are "puffs of air" created from the pancaking floors above. But there are no pancaking floors above, they are not air but pulverized building materials, they occur precisely at the center of the building in an "open office plan", and finally, the 160 to 200 feet per second speed of this debris suggests they could only have been propelled by explosives.

The debris was equally distributed across a 1,400 ft. diameter. There are no "pancakes" stacked up at the bottom of either tower!

The FEMA report notes:
"The results of the examination are striking. They reveal a phenomenon never before observed in building fires: eutectic reactions, which caused "intergranular melting capable of turning a solid steel girder into Swiss cheese.... Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation." NIST dropped this like a hot potato. These are all tell tell signs of the use of thermate (sulphur + thermite) incendiary cutter charges."

It takes thousands of degrees to bend steel like this without buckling. Thermate cutter charges create over 4,500°F. Fires — even with jet fuel — create only 1,700°F maximum.

Physics professor Steven Jones finds, in this previously molten sample from the WTC, the chemical traces of Thermate — including Fluorine, Manganese, Sulphur, Potassium, etc.

Steven Jones, PhD physicist discovers previously molten iron spheres in the WTC dust which blanketed lower Manhattan. Sizes are up to 1/16" diameter. The findings are corroborated by EPA but not explained. Molten iron is the byproduct of Thermite. It contains the chemical signature of thermate.

The Smoking Gun: Microspheres carry signature of Thermate!

The concrete and other building contents were pulverized to a thick ground hugging pyroclastic dust — much of which was <100 microns — the width of a human hair. The gravitational potential of the building at 100,000KWH does not account for the concrete pulverization or the rapid expansion of the dust clouds.

This is all that is left of the concrete floors, gypsum wall board, steel decking, office furniture, office machinery, filing cabinets. The toxic dust averages 4" deep — throughout lower Manhattan.

Controlled demolitions can be performed in a variety of ways.
