The largest terror attack in our nation’s history left images seared into our conscience that will never be forgotten. But for those caught in the middle, the memories are as strong today as they were in 2001. Hear the harrowing experiences of a trader who worked in the World Trade Center, a firefighter, a Port Authority officer, an ER doctor, an NYPD rescue worker, and a news reporter who were at Ground Zero, as well as a Pentagon contractor, an Airfone operator communicating with Flight 93, and the head of FAA operations as they experienced the tragic unfolding of a day none had dreamed possible.
