"Others, who had made it down stairwells towards - or even out into - the lobby giving out on to the street and freedom, were told to run back upstairs, so that during the crucial 15 minutes of what should have been escape, there was confusion and a two-way rush along the panic-stricken arteries of life."

Rudolph Giuliani's Warning
Rudolph Giuliani, mayor of New York City on 9/11/01, has stated that he was at the base of the Twin Towers just minutes before the explosive collapse of the South Tower and then went to 75 Barclay Street – where he had a makeshift command center.
QUESTION: Mr. Mayor, just to clarify something that Mr. Kerik said you were about 10 minutes past when you were standing with several of the high ranking officers who you lost and then you went to Barkley [sic] Street, have you thought about that 10 minute gap, how you were 10 minutes from being in a horrible situation?
GIULIANI: I haven't had a chance to think about it.
QUESTION: Then that could of evacuate the 10–you would have been with them 10 minutes earlier before the building collapsed?
GIULIANI: The–some of the people that we lost we saw like Father Judge (ph) and Chief Gansy (ph), Bill Fehan (ph), we saw them about 10 minutes before–before we went over to 75 Barkley [sic] street. And I talked to their families and I explained to them that they were working very hard and they were working at what they loved to do. And I'm sure their efforts will end up having saved other lives and their families can be very proud of them.
