[CTRL-C] [CTRL-V]Gramsci, you dope, why are there are all these photos of demolition squibs ejecting from known controlled demolitions, before any pancaking, if the cause is pancaking??? Your 'explanation' for these squibs is good comedy. Your faith in these liars is bottomless. No one is more faithful than you ( or more terrified of peer pressure...)
Squibs appear, no pancaking:

"Melted" Steel"
Claim: "We have been lied to," announces the Web site AttackOnAmerica.net. "The first lie was that the load of fuel from the aircraft was the cause of structural failure. No kerosene fire can burn hot enough to melt steel." The posting is entitled "Proof Of Controlled Demolition At The WTC."
FACT: Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength — and that required exposure to much less heat. "I have never seen melted steel in a building fire," says retired New York deputy fire chief Vincent Dunn, author of The Collapse Of Burning Buildings: A Guide To Fireground Safety. "But I've seen a lot of twisted, warped, bent and sagging steel. What happens is that the steel tries to expand at both ends, but when it can no longer expand, it sags and the surrounding concrete cracks."
"Steel loses about 50 percent of its strength at 1100°F," notes senior engineer Farid Alfawak-hiri of the American Institute of Steel Construction. "And at 1800° it is probably at less than 10 percent." NIST also believes that a great deal of the spray-on fireproofing insulation was likely knocked off the steel beams that were in the path of the crashing jets, leaving the metal more vulnerable to the heat.
But jet fuel wasn't the only thing burning, notes Forman Williams, a professor of engineering at the University of California, San Diego, and one of seven structural engineers and fire experts that PM consulted. He says that while the jet fuel was the catalyst for the WTC fires, the resulting inferno was intensified by the combustible material inside the buildings, including rugs, curtains, furniture and paper. NIST reports that pockets of fire hit 1832°F.
"The jet fuel was the ignition source," Williams tells PM. "It burned for maybe 10 minutes, and [the towers] were still standing in 10 minutes. It was the rest of the stuff burning afterward that was responsible for the heat transfer that eventually brought them down."
4. Weren't the puffs of smoke that were seen, as the collapse of each WTC tower starts, evidence of controlled demolition explosions?
No. As stated in Section 6.14.4 of NIST NCSTAR 1, the falling mass of the building compressed the air ahead of it—much like the action of a piston—forcing smoke and debris out the windows as the stories below failed sequentially.
These puffs were observed at many locations as the towers collapsed. In all cases, they had the appearance of jets of gas being pushed from the building through windows or between columns on the mechanical floors. Such jets are expected since the air inside the building is compressed as the tower falls and must flow somewhere as the pressure builds. It is significant that similar “puffs” were observed numerous times on the fire floors in both towers prior to their collapses, perhaps due to falling walls or portions of a floor. Puffs from WTC 1 were even observed when WTC 2 was struck by the aircraft. These observations confirm that even minor overpressures were transmitted through the towers and forced smoke and debris from the building.

Man, look at those squibs. Dead center. That's professional demolition work.

Outlook for 2008-09
Eighteen months into his six-year term, the president, Felipe Calderon, has just a small window of opportunity to advance a controversial energy reform before attention focuses on the 2009 mid-term election.
A high level of violence stemming from organised crime represents a serious challenge to Mexico's deficient security forces. Mr Calderon's authority will be partly dependent on his ability to achieve improvements in this area.
Rising oil revenue will facilitate a countercyclical increase in expenditure in 2008 without jeopardising the fiscal balance. However, energy reform to raise oil output will be needed to contain contingent liabilities in the longer term.
With the US in recession in the first half of 2008 under the Economist Intelligence Unit's central forecast, we expect GDP growth in Mexico to slow to 2.3% in 2008 before recovering slightly to 2.5% in 2009.
We now expect inflation to end 2008 at 4.8%, significantly higher than the 4% target ceiling. Our projection of a decline to 4% at end-2009 is vulnerable to a risk of wider contamination from food and producer price pressures.
The trade deficit will widen further in 2008-09 despite historically high oil prices, as a contraction in US import volumes hits export earnings.
