This week marks 18 years since the September 11th terror attacks.

On that morning, students at Stuyvesant High School — just blocks away from the World Trade Center — started what they thought would be just another ordinary day at school.

A new documentary airing this Wednesday at 9 p.m. on HBO recounts the experiences of eight former students from that fateful day.

The film is called "In the Shadow of the Towers: Stuyvesant High on 9/11." 

Director Amy Schatz, along with two of those former students, Mohammad Haque and Liz O'Callahan, stopped by "Mornings On 1" to discuss the film.
