On September 11, 2001, Fabrizio Bivona was one of hundreds of first responders to the terrorist attacks at the World Trade Center. He is also the author of “Gone But Not Forgotten”. Bivona shares how 9-11 unfolded for him, what it was like to work in the eerie silence of the collapsed towers in a desperate search for his colleagues, why he vowed to make sure his friends were properly remembered and how the selflessness of first responders was on display through September 11th as it is every day.
