What Happened at the United Nations on September 11, 2001

Stephane Dujarric is a long serving United Nations spokesperson who on September 11th, 2001 was at his office at the United Nations when planes struck the World Trade Center. I've known Stephane Dujarric a long time and knew that he was in the building that day, but I'd not spoken about it with him until now.  He offers a grounds-eye view of what it was like to be at the United Nations that day, and as a long serving senior UN spokesperson he is able to give some perspective on how those attacks forever changed the United Nations.
