118 Witnesses:
The Firefighters’ Testimony to Explosions in the Twin Towers
...
The Surprising Collapses
Although the 9/11 Commission Report acknowledges that fire chiefs on the scene thought the collapse of the Towers was impossible,[13] it is worth emphasizing the unanimity of the FDNY personnel on this point.
Here are typical comments:
“...it took me a long time before I could accept the fact that even after you could see that the
tower wasn't there you said it had to be there somewhere. You couldn’t believe that it had come
down.” (Captain Michael Donovan, 9110205)
“I was kind of in disbelief that the building was actually collapsing. I kind of stopped to say,
well, maybe that was a piece of the facade. I couldn’t believe that the entire building was going
to collapse in one heap.”(Captain Charles Clarke, 9110250)
“Once again, I’m doing this 23 years...This changed all the rules. This changed all the rules. This
went from a structure to a wafer in seconds, in seconds. I couldn’t believe the speed of that tower
coming down. I heard the rumble, I looked up, debris was already 50 feet from the ground...”
(Sergeant James Canham, 9110370)
“I’ve worked in Manhattan my whole career in high rises and everything else...you looked back,
all you see--you know how fast those buildings came down...it just doesn’t click that these
buildings can come down...you just couldn’t believe that those buildings could come
down...there’s no history of these buildings falling down.” (Lieutenant Warren Smith, 9110223)
“whoever in their right mind would have thought that the World Trade Center would ever fall
down...Nobody in the world, nobody ever would ever have thought those buildings were coming
down.” (EMS Captain Mark Stone, 9110076)
