And there was also warning that building 7, which was not even hit by a plane, was going to collapse. Indeed, people “waited around” for the building to collapse.
For example, right before WTC7 came down, a NYPD police officer said clear away, the whole building is "about to blow up"
A firefighter stated "They moved us back south. We ended up back up on Vesey Street and West Street and just hanging out until tower 7 came down. After tower 7 came down, we went right to work over at tower 7 to put the fires out" (page 9)
Another firefighter testified "Once they got us back together and organized somewhat, they sent us back down to Vesey, where we stood and waited for Seven World Trade Center to come down" (page 14)
A firefighter said "I don't know what happened to No. 7. I knew the building was coming down" (page
A lieutenant firefighter said Basically, we fell back for 7 to collapse, and then we waited a while and it got a lot more organized, I would guess" (page 17)
A paramedic testified “Then it was about 5:00 . . . We didn't do any further because building number seven was coming down. That was another problem, to wait for building seven to come down, because that was unsecure. It was about 5:30 that building came down” (Pages 13-14)
