Joe Casaliggi "The building collapsed to dust"
And Chief Orio Palmer reported from 78th floor of the South Tower, saying
"we've got two isolated pockets of fire. We should be able to knock it down with two lines."
Anyhow, what official story is saying is that these two bears will get to the ground at the same time despite the right one has got so much blockage to go through.
Would you believe that?
