C'mon LeftBehind you know that PM garbage has been de-bunked for what it was...Government sanctioned BS.

Confederacy are you talking about the picture with the woman standing right next to torn beams where the plane hit? If so that was taken early after the initial crash and the fires had not reached their full potential yet.

Fires can only get so hot in open atmosphere, and no hotter without special conditions like pre-heated air. That max temperature, with a perfect fuel/air ratio, at sea level, is around 825 C, and the black smoke coming from the Twin Towers after the jet fuel burned away indicated a poor fuel/air ratio, so you probably didn't even have anything near that sustained in the WTC. Not hot enough.

I have yet to see anyone debunk the info contained in the PM peice, because it is factual. The so-called debunkings I've seen here call foul because they didn't cover everyones pet theories.

To the contrary, there was nothing strange about the seismic spikes recorded by the Palisades station. As the video and photographic evidence shows, the towers exploded into expanding clouds of rubble that were about 400 feet from top to bottom by the time they reached the ground. Those rubble clouds contained virtually all of the mass of towers -- thousands of tons of rubble falling from as high as 1000 feet. That could certainly be expected to produce pronounced seismic waves.

Whats really absurd about the 9/11 collapse theories is that fuel survived the impact with the towers.
The idea that fuel ignited on impact, then somehow found it's way to the basement to ignite a second time is so ludicris that I have trouble even saying it.
When a plane crashes into a building the jet fuel blows up right then and there. Boom oneshot deal. All thats left is the inferno. It can't mysteriously bend the rules of physics. The fuel can't just say to itself, Ok one half of us will explode while the otherhalf finds it's way to the basement to ignite a second time. It just doesn't work that way.
Maybe things go that way in Bush La La land but in the real world things are a little different.

Neither that or thermite in the basement make any sense, as the buildings fell from the top down. While many of you seem to think this is a characteristic of controlled demolition, it is not.
Most demolition's are done from the bottom up. Please show me some pictures of a building that destroyed like the WTC towers, if you are going to insist it resembled controlled demolition.
All that proved is that concrete cores will not collapse, and that the steel sections on that particular builiding will collapse.

On top of that airplane fuel doesn't burn remotely close to the tempatures needed to melt steel. Does anybody remember the skyscraper in Madrid?
Please notice molten metal and red hot, not molten steel.
Dr. Keith Eaton toured Ground Zero and stated in The Structural Engineer , "They showed us many fascinating slides [Eaton] continued, ranging from molten metal which was still red hot weeks after the event, to 4-inch thick steel plates sheared and bent in the disaster." (Structural Engineer , September 3, 2002, p. 6;.)
The observation of molten metal at Ground Zero was emphasized publicly by Leslie Robertson, the structural engineer responsible for the design of the World Trade Center Towers, who reported that "As of 21 days after the attack, the fires were still burning and molten steel was still running." (Williams, 2001, p. 3.)
Sarah Atlas was part of New Jersey's Task Force One Urban Search and Rescue and was one of the first on the scene at Ground Zero with her canine partner Anna. She reported in Penn Arts and Sciences , summer 2002, "'Nobody's going to be alive.' Fires burned and molten steel flowed in the pile of ruins still settling beneath her feet." (Penn, 2002
Dr. Allison Geyh was one of a team of public health investigators from Johns Hopkins who visited the WTC site after 9-11. She reported in the Late Fall 2001 issue of Magazine of Johns Hopkins Public Health, "In some pockets now being uncovered they are finding molten steel.
Underground it was still so hot that molten metal dripped down the sides of the wall from Building 6. (Kenneth Holden, Commissioner of the New York City Department of Design and Construction)
The numerical analyses demonstrated that the protected composite trusses would resist 60 minutes of the standard fire within a deflection of L/100, under loadings of 4.8kN/m2 and 3.9kN/m2. Unprotected simply supported trusses initially lost stability at 12.5 and 13.4 minutes due to buckling of the second compressive web diagonal. Both of the protected trusses with a supporting column deflected approximately L/90 at 60 minutes of the standard fire without any local instability occurring. The unprotected composite truss with a supporting column was shown to resist for 16.1 and 18.0 minutes of the standard fire before the progressive buckling of web compression diagonals caused a loss of stability.
