Inside the Towers: Summary of Witness Accounts

This summary is based only on the accounts I compiled for this paper. That compilation is a sample only and should not be taken as comprehensive. These lists do not include some similar statistics such as those in NIST NCSTAR 1-7 (Occupant Behavior, Egress, and Emergency Communication) or NIST NCSTAR 1-5 (Reconstruction of the Fires in the World Trade Center Towers). I haven't updated this list since compiling several more accounts.

Bold floor numbers indicate multiple reports.
