Updated September 9
It’s hard to believe that 20 years have passed since the September 11 terrorist attacks in 2001. THIRTEEN commemorates the 20th anniversary of this devastating attack and losses with television programs of hope and healing, remembrance and reflection, honoring the heroes, victims, and resilient spirit of New Yorkers. The programming also looks at investigations into who was involved in planning the terrorist acts, and the struggle to have the government recognize the public health crisis caused by the collapse of the World Trade Center.
Our films are listed below in order of broadcast date, beginning August 10. On September 10, 2021, three focused on New York City’s first responders will air, starting at 9 p.m., 9:30 p.m. and 10 p.m. On September 11, Great Performances presents a very special live broadcast from the Metropolitan Opera House; the commemorative concert will be held the first there since March 2020.
Frontline: In the Shadow of 9/11
Tuesday, August 10, 9 p.m.

A searing tale of injustice set in the aftermath of the September 11 attacks, this investigative documentary tells the story of the so-called “Liberty City Seven” – a group of young Black men accused of assisting Al Qaeda in a plot to blow up buildings within the United States. Although these young men had no weapons and never communicated with Al Qaeda, five of them were convicted at the third federal trial, after two mistrials.
In an article for The Intercept, journalist Trevor Aaronson delves into FBI investigations of domestic terrorism, including the Liberty City Seven, the Herald Square bombers of NYC, and more. The U.S. government has prosecuted more than 800 people for terrorism since the 9/11 attacks, and more than 400 were released by 2017.
Terrorism is a frequent topic on Frontline; see the program’s reporting on terrorism around the world, from domestic terror in the U.S. to ISIS, Al Qaeda, and far-right hate groups on Frontline.org.

Tuesday, August 31, 9 p.m.

PBS presents a look at the lives of young people who were not yet born when their fathers perished in the attacks on the Twin Towers in New York City – including childhood milestones and how they learned of their parent’s death. Bill Gardner, who commissioned the film for PBS, says, “The world, not just America, was forever changed as a result of 9/11 and its aftermath, and we wanted to explore that ongoing, global impact in a very direct, personal way. The lives of these young people and their families have been shaped by 9/11 in a variety of intimate ways, and their openness to sharing their lives allows us to thoughtfully explore the nuances of the 20 eventful years since that unforgettable day.”

Twenty years later, employees who still work for this relatively unknown agency tell their story in the documentary NYC DDC 9/11. The sights, smells, and demands of the job still haunt them. Their success in getting it done and bringing back their city remains their greatest achievement.
Typically the NYC DDC helps construct new or renovated civic structures such as firehouses, libraries, police precincts, courthouses and senior centers, and also maintains infrastructure such as sidewalks, streets, water mains and sewers. Learn more about the city agency and see its current job listings on the NYC DDC web page.
