15 years have passed since that crisp fall morning when Americans were shocked out of their daily routines as they stood stunned at the spectacle of attacks on the World Trade Center, then the Pentagon and finally the crash at Shanksville.  Through the hours and days that followed Americans watched as firemen, police and average citizens worked to save lives and restore security to our nation.  The best of America was on display in the midst of the worst attack on US soil.  We will never forget.
