The World Trade Center was destroyed on 09/11/2001 by hijackers who crashed commercial airline flights into the twin towers. As I write this, it is estimated that 5,000 people lost their lives.
The links below provide a list of the victims in each aircraft or building. The lists were collected from msnbc.com on 9/11/2003. I have provided links the original pages; the contents were copied here in case the links on msnbc.com are ever removed.
