"It was really to kind of give an unflinching account, and honor and respect the lens of those who survived it," said TJ Martin, an executive producer of the series. "In the course of watching it, you're getting the granular details from so many different points of view from individuals. They are incredible tales of survival from individuals who were on the 80th floor of South Tower, the first responders, even members of the media who showed up to document the events and feel it in real-time."
"The hope comes from across the board, from all different kinds of walks of life, points of views and different experiences," Martin added. "The amount of selflessness that was displayed was surprising in the best of ways."
