".....just a little bit after 5:00 - walked around it - saw a hole - I didn't see a hole bad enough to knock a building down though - there was definitely fire in the building - I didn't hear any creaking - I didn't hear any indication it was gonna come down - the thing started peeling in on itself - the whole time you were hearing, "thum, thum, thum, thum, thum" - I think I know the sound of an explosion when I hear it."

I thought I would just sum up a few things
1. "I didn't see a hole bad enough to knock a building down" I agree with this statement, I don't believe the hole wasn't big enough alone to knock down the building. As a side note many firefighters on the scene clearly stated concerns of a falling building. Why does Craig disgard this?
2. "There definitely was fire in the building" Good.... in fact I believe very intensive fire as seen from a (probable) steel beam on figure 10.

3. "I didn't hear any creaking"
Well there are two sources that disagree.
James Mcglynn:
Just when you thought it was over, you're walking by this building and
you're hearing this building creak and fully involved in flames. It's like, is it coming down next? Sure enough, about a half an hour later it came down. –FDNY Lieutenant James McGlynn

But they had a hoseline operating. Like I said, it was hitting the sidewalk across the street, but eventually they pulled back too. Then we received an order from Fellini, we’re going to make a move on 7. That was the first time really my stomach tightened up because the building didn’t look good. I was figuring probably the standpipe systems were shot. There was no hydrant pressure. I wasn’t really keen on the idea. Then this other officer I’m standing next to said, that building doesn’t look straight. So I’m standing there. I’m looking at the building. It didn’t look right, but, well, we’ll go in, we’ll see.
We headed toward 7. And just around we were about a hundred yards away and Butch Brandies came running up.
He said forget it, nobody's going into 7, there's creaking, there are noises coming out of there, so we just stopped. And probably about 10 minutes after that, Visconti, he was on West Street, and I guess he had another report of further damage either in some basements and things like that, so Visconti said nobody goes into 7, so that was the final thing and that was abandoned.

4. "I didn't hear any indication it was gonna come down"
If refering to the creaking sound then see 3. If refering to warnings of collapse, this has been strongly refuted by numerous sources. (If someone is really interested to read them, I'd start with Gravys paper)
5."the thing started peeling in on itself - the whole time you were hearing, "thum, thum, thum, thum, thum" - I think I know the sound of an explosion when I hear it."
Clearly falling floors make sounds when falling. I would certainly expect a thum, thum, thum sound, but we have little testimony or audio supporting demolition type explosions occuring during the collapse.
