Has anyone hear ever seen a plane first, then heard its noise later?

That argument is so stupid, the plane was not solid steel, there were huge glass windows between the steel columns. Even a small Cesna would not "bounce off" the glass windows of a building, a multi-ton passenger jet certainly would not.

Good point. MOST of the outside of the WTC was GLASS. Even the Pentagon was considered blast RESISTANT and not 3 solid feet of concrete.

Here's an F-4 hitting a concrete wall at 500mph.

I don't think that the F-4 is made mostly of steel. Do you have any sources for that? I can't think of any aircraft made mostly of steel.

Consider an explosion itself. When you detonate a brick of C4, you're basically turning it into a ball of expanding gas. That's carbon dioxide and water vapour which, because they are moving fast enough, can destroy steel, concrete, or whatever else you like. The hardness of the material means nothing - what matters is the energy density it is carrying.

Thanks for the post Trevor. Could you please post the engineering drawings and/or pictures that would substantiate your statement that "MOST of the outside of the WTC was GLASS."

The plane disappearing into the building, both shredding each other to bits, etc.

As far as my personal flying experience goes, I have about 10 hours in paper airplanes, fifty years ago.

They all crashed.
