Peter: Now this is what it looked like moments ago.

My gosh.

The southern .. tower ... 10 o'clock eastern time this morning, just collapsing on itself. This is a place where thousands of people work. We have no idea what caused this. Um .. If you wish to bring ah .. anybody who ever watched a building being demolished on purpose knows .. that if you're going to do this you have to get at the .. at the under infrastructure of a building and bring it down.

Don: Peter?

Peter: Yes, Don.

Don: What appeared to happen from my vantage point .. the top part of the building was totally involved in fire, and there was .. there appeared to be no effort possible to put that fire out. It looked like the top part of the building was so weakened by the fire that it just .. the weight of it just collapsed the rest of the building .. that's what appeared to happen. I did not see anything happening at the base of the building. It all appeared to to start at the top and then just collapse the rest of the building by the sheer weight of the top.

There was no explosion or anything at the base part of it, but I .. I did see that the top part of it started to collapse, the walls started to bulge out, bricks, glass, things coming out, and then it collapsed in on itself, and it appeared to just fold down from there, from the very top.

Peter: Thanks, Don, very much. Um, just looking at that, I don't know why, but I'm .. when was the last time the United States was attacked in this fashion it was Pearl Harbor in 1941.
