Let me save you a step. Anon was there on the street and saw planes go in.
I escaped barely. As I got the last train going to brooklyn - I was screaming at commuters to stay on the train and not get out. They all thought I was crazy.
On my way running to the train there were 4 block long lines at every payphone cuz comms dropped. (COMMS DROPPED BEFORE THE TOWERS FELL).
It got so much worse after that.
