Stephen Gregory , Assistant Commissioner (F.D.N.Y.) flashes, explosions p 14
I know I was with an officer from Ladder 146, a Lieutenant Evangelista, who ultimately called me up a couple of days later just to find out how I was. We both for whatever reason -- again, I don't know how valid this is with everything that was going on at that particular point in time, but for some reason I thought that when I looked in the direction of the Trade Center before it came down, before No. 2 came down, that I saw low-level flashes. In my conversation with Lieutenant Evangelista, never mentioning this to him, he questioned me and asked me if I saw low-level flashes in front of the building, and I agreed with him because I thought -- at that time I didn't know what it was. I mean, it could have been as a result of the building collapsing, things exploding, but I saw a flash flash flash and then it looked like the building came down.
Q. Was that on the lower level of the building or up where the fire was?
A. No, the lower level of the building. You know like when they demolish a building, how when they blow up a building, when it falls down? That's what I thought I saw. And I didn't broach the topic to him, but he asked me. He said I don't know if I'm crazy,

My lieutenant said he looked down at the first floor, and he could see the first floor of the south tower like exploding out. I looked up. I looked up, and the sky was filled with that debris cloud.

It looked like some kind of maybe a command post or something was there. I Started to walk towards it, and that's when the building came down. I heard an explosion and turned around and the building was coming down. At that point, we dropped everything we had. We started to run north on West Street. At that point, we were overcome with the cloud and it looked like -- felt a lot of wind again, got knocked down.

and the WTC1 building engineer gave the most details regarding the
basement explosions.
And post collapse cleanup noticed the missing foundation where the explosions took out part of the foundation.
