"Have you seen the laboratory studies on 9/11? They say with 100% no doubt that the planes hitting the towers could not have caused the towers to collapse and even if they did the towers would not have come down in that fashion. I did my own little look into it. I watched all the video of 9/11 I could find on abc,cnn,foxnews,cbs, and some other big media outlets and all the videos are the same. 15 seconds prior to the collapse of the first tower that fell there was a HUGE cloud of smoke coming from the base of the tower. This suggests there had to be a explosions. Not only that I also looked at the video to see how the material was falling and you can clearly see in some videos that the steel was smoking where it broke. Not melted but smoking as if there was some kind of explosion that caused the pieces of steel to break. Not only that but there has been many many buildings that have burned for over 24 hours that have the same design as the WTC and they never collapsed. One happened in 2005 in madrid i believe where the building burned for 28 hours and i saw some video of it and the fire was pretty intense and afterwards the building still stood but it was just a skeleton of the steel. Steel could not have melted from the fires pure chemistry and physics dictates that there is no possible way that the air plans caused the towers to collapse. There had to have been some kind of other key part that caused it. You can't throw out empirical evidence like this. Something fishy has been going on and Rudy is unwilling to take a look at it and he was freakin there for gods sake. "
