The line in the vid where they go on about "pull" amazed me because I immediately thought "right, pull out" from the operation; funny that moments later they came up with the alternate explanation.

Also refer to Chief Hayden's comments, which show that this line in the video is absolute B.S. (down-vote for this fragment alone)

Fire much larger than this video suggests:

No water pressure:

Not a profitable venture, as described by some:

"You couldn�t really see from where we were on the west face of the building, but at the edge of the south face you could see that it was very heavily damaged."
We have guys trying to make their way up into the pile, and they�re telling us that 7 is going to fall down � and that was one of the directions from the command post, to make sure we clear the collapse zone from 7 and this is a 600-foot-tall building, so we had to clear a 600-foot radius from that building. Guys are looking at me when I�m telling them to move away, we�re over by the north tower and we got to get out of here."

If you read on, you hit the really sad story about how he found the original firefighters' command post...

Chief Hayden (who escaped just barely the second tower's collapse):
"By now, this is going on into the afternoon, and we were concerned about additional collapse, not only of the Marriott, because there was a good portion of the Marriott still standing, but also we were pretty sure that 7 World Trade Center would collapse. Early on, we saw a bulge in the southwest corner between floors 10 and 13, and we had put a transit on that and we were pretty sure she was going to collapse. You actually could see there was a visible bulge, it ran up about three floors. It came down about 5 o�clock in the afternoon, but by about 2 o�clock in the afternoon we realized this thing was going to collapse."
Firehouse: Was there heavy fire in there right away?
Hayden: No, not right away, and that�s probably why it stood for so long because it took a while for that fire to develop. It was a heavy body of fire in there and then we didn�t make any attempt to fight it. That was just one of those wars we were just going to lose. We were concerned about the collapse of a 47-story building there. We were worried about additional collapse there of what was remaining standing of the towers and the Marriott, so we started pulling the people back after a couple of hours of surface removal and searches along the surface of the debris. We started to pull guys back because we were concerned for their safety."
Firehouse: Chief Nigro said they made a collapse zone and wanted everybody away from number 7� did you have to get all of those people out?
Hayden: Yeah, we had to pull everybody back. It was very difficult. We had to be very forceful in getting the guys out. They didn�t want to come out. There were guys going into areas that I wasn�t even really comfortable with, because of the possibility of secondary collapses. We didn�t know how stable any of this area was. We pulled everybody back probably by 3 or 3:30 in the afternoon. We said, this building is going to come down, get back. It came down about 5 o�clock or so, but we had everybody backed away by then."
