Laughed my head off. You folks really need to look at the following link in the Bitcointalk forum. They have this hot debate going on for months, now, as to whether or not 9/11 was an inside job.

I'm looking at the info provided on this site: http://www.popularmechanics.com/military/a6384/debunking-911-myths-world-trade-center/ According to this article, jet fuel burns between 800 - 1,500 degrees F. But where? In the combustion chamber of a jet engine with ideal fuel/air mixtures? The black smoke pouring out of the WTC towers indicated an oxygen-starved flame - definitely on the low end of that range. Also, consider how slowly the smoke appears to be rising. Distance to camera may be a factor here, but 800 degree air would be hauling butt skyward. https://www.youtube.com/watch?v=7uKfER3-Vm4 In my youth, I sat in a car for 20 minutes or better within 1,000 feet of the 2nd largest sawmill in the South as its inventory of millions of board feet of (mostly) pine wood burned to the ground. (the mill was spared) The smoke was clear. The flames were hot enough to produce "fire-tornadoes". Even 1,000 feet away, the heat would have been uncomfortable except for the fact it was right at freezing outside. The smoke rose vertically rapidly, even soon after the fire started, and spread out horizontally high above when it reached an inversion layer. Look at the smoke in this video. Note absence of fire tornadoes. Despite fires visible in this video, I think the slowly rising smoke is a better indication of how hot materials in the building were. In college, I took an "Industrial Processes" course. As part of that course, classmembers were required to construct a belt-driven table-mounted arbor wheel. The housings were aluminum. At the foundry, we were told the aluminum had been in the furnace for considerable time (maybe even overnight) and the Professor thanked the foundry attendant for taking care of all that so the aluminum would be melted when we got there. While the blacksmith in the video tells you about the steel being in a FURNACE, just like the aluminum for the arbors was in a furnace, he does not tell you how long it was in there. The article cited above states that spots in the fire were over 1,800 degrees F. Ok, but that is SPOTS IN THE FIRES. If the building is ventilated well enough for fire to burn at all, it is also ventillated enough to bring in cooling (relatively speaking) air. So never mind any of the temperatures in the article. What was the temperature of the air in contact with the steel structural memebers? It is not enough to heat the steel and concrete at critical support points - surrounding materials have to be heated as well. This is because not only is heat CONDUCTED away from the site of heating, it is also RADIATED away to cooler objects nearby. I base this on what I was told about WWII high altitude bombers. Crews complained the cabin was cold. This was odd since thermometers indicated an air temperature of 80 degrees. The problem was that separated from that 80 degree air was air at -50 blocked only by the thin aluminum skin of the plane. Body heat of the crewmembers was being RADIATED to that cold air outside. To make the crew comfortable, air temperature had to be raised to 115 degrees inside the cabin. How many times after a clear night with a low of 35 to 38 have you gone to your vehicle to find the roof and maybe even the windshield frosted up? That is radiative cooling. Long story short, I don't think there was enough time (between impact and collapse) to get everything hot enough to fail from just fires. FWIW. DC Treybil

Ahhhh,... But I'm looking for a reason for the molten metal pouring out of excavator buckets days AFTER the collapse. Just say'n. Peace, Ernie
