This is how I remember. Every year, I watch a good chunk of recorded broadcasts coming from the morning of 9/11/2001. Archive.org has collected and archived a good chunk of live television from major news networks in order to preserve the events in an uninhibited manner. It is a truly chilling feeling to hear the confusion and chaos of that morning as it was happening. That morning changed the world forever and with each passing second you can hear the innocence of an entire American generation float away.
