Speaking of steel buildings collapsing because of fire, something that "never happens":

Perhaps they just decided to "pull" the toy factory?

I have a question. This time it's a serious one:

How could an explosion of 15,000 gallons of Jet-A fuel NOT bring the Twin Towers down? My argument has always been that the blasts alone were quite sufficient to topple these structures.

If my math is correct, the fuel in the 707 tanks had energy content of 2*10^12 Joules. The energy output of 1 kilotons of TNT 4.184*10^12 Joules. So 15,000 gallons of Jet-A can create a bang of up to .478 kilotons worth of TNT. Does anyone know of a structure which could withstand that much destructive power?

Now, I understand that burn time is a factor here. The longer the burn time, the less powerful the blast. But still, we're looking at pretty powerful stuff.

My academic training is neither in physics nor engineering, though. And I'm well aware that my assumptions may be pretty sophomoric here. Who can help?

Here are my sources:

I saw that video. I didn't realize the Twin Towers were made from corrugated cardboard.
