Still, the towers weren't dropped by aircraft. Steel melts 1000 degrees hotter than jet fuel.
First off, light a match in a big room..does the room get hotter? Now light a match and cup your hands around it...hotter? Jet fuel burning in an enclosed area will create a lot more heat than jet fuel in an open air field. Secondly, the steel wouldn't even need to melt. Trying to apply common sense to the physics at play in a situation involving the internal decapitation of hundreds of tons of rock and steel several hundred feet up in the air is pretty insane. Is there a chance there was some kind of conspiracy at play...sure...but this idea that a 747 hitting the top of a building like that couldn't take it down is just stupid.
