Our nation still mourns the loss of those who died in the attacks of 9/11 twelve years ago.  A picture can bring back a flood of memories.  These are some of the most iconic images from September 11, 2001.

Wherever you were on that horrible day, I'm sure you remember seeing these pictures and watching in shock as the Twin Towers came down, a hijacked plane crashed in a Pennsylvania field and the Pentagon was attacked.  Our nation will never forget those we lost and those whose lives were forever changed by the September 11th attacks.
