I remember it from months ago. As I recall a fireman on the scene had been told by someone in Giuliani's office that they should evacuate because
they had been told that the building (I can't remember which tower it was.) was going to come down.
• At 9:30 am, a FDNY Chief Officer inside WTC 1 feels the building move and makes the decision that the building is no longer safe.
• At 9:49 am, NYPD helicopters provide a radio report stating that “large pieces” are falling from WTC 2.
• At 10:07 am, NYPD aviation units warn that WTC 1 may collapse.
• At 10:20 am, NYPD aviation unit reports that WTC 1 is leaning to the south.
FDNY Assistant Chief Joseph Callan: "Approximately 40 minutes after I arrived in the lobby, I made a decision that the building was no longer safe.
And that was based on the conditions in the lobby, large pieces of plaster falling, all the 20 foot high glass panels on the exterior of the lobby
were breaking. There was obvious movement of the building, and that was the reason on the handy talky I gave the order for all Fire Department units
to leave the north tower."
Callan: "For me to make the decision to take our firefighters out of the building with civilians still in it, that was very tough for me, but I did
that because I did not think the building was safe any longer, and that was just prior to 9:30."–
EMS Division Chief John Peruggia: "I was in a discussion with Mr. Rotanz and I believe it was a representative from the Department of Buildings, but
I'm not sure. Some engineer type person, and several of us were huddled talking in the lobby and it was brought to my attention, it was believed that
the structural damage that was suffered to the towers was quite significant and they were very confident that the building's stability was
compromised and they felt that the north tower was in danger of a near imminent collapse.
I grabbed EMT Zarrillo, I advised him of that information. I told him he was to proceed immediately to the command post where Chief Ganci was located.
Told him where it was across the street from number 1 World Trade Center. I told him "You see Chief Ganci and Chief Ganci only. Provide him with the
information that the building integrity is severely compromised and they believe the building is in danger of imminent collapse." So, he left off in
It wasn't Giuliani telling the fireman - it was the fireman who recognized
the signs the building was becoming upstable and started to clear
