Immediately after 9/11, investigators began piecing together the plot. In the flight manifests, they discovered a pattern: A team of five terrorists hijacked every plane that day, except for one. United Airlines Flight 93 had only four hijackers. Investigators believed one person was missing from that group. Who was the 20th hijacker — if there even was one? And is there a 9/11 hijacker still on the loose?

Who was the 20th hijacker?

Through a series of riveting, complex narratives, LONG SHADOW makes sense of what people know — and what they thought they knew — about the most pivotal moments in U.S. history, including Waco, Columbine, Y2K, 9/11, COVID-19, January 6, and beyond.  Hosted by Pulitzer-finalist historian, author, and journalist Garrett Graff, this Peabody-nominated podcast has been called “rigorous, authoritative, and an electrifying listen” by the Financial Times and honored as one of the year's best podcasts by The Atlantic, Audible, Mashable, and The Week. A winner of the Edward R. Murrow Award and the RFK Human Rights Journalism Award, it has also been honored with five Signal Awards, including for Best History, Best Documentary, and Best Activism, Public Service, &amp; Social Impact Podcast. The second season of LONG SHADOW has been added to the history program at the University of Houston and the third season has been integrated into Harvard Law School's curriculum on the Second Amendment. Season 4 LONG SHADOW: BREAKING THE INTERNET When was the last time you felt good about the internet? Today’s online landscape is a harrowing one. People screaming at each other on social media. Violent videos going viral. Cyberbullying, racism, misogyny. Back in the day, the web gave power to the people, and going online could actually be fun. LONG SHADOW: BREAKING THE INTERNET retraces 30 years of web history — a tangle of GIFs, blogs, apps, and hashtags — to answer the bewildering question many ask when they go online today: “How did we get here?” It’s the story of mankind’s greatest invention, a tool that gave everyone access to all the world’s information and unlocked democracy across the globe. But LONG SHADOW: BREAKING THE INTERNET is also about the biggest crisis facing society today: how the web's unlimited feed of data morphed into a firehose of hoaxes, conspiracy theories, and lies that divided Americans over things we once agreed on, like science, diversity, and even democracy itself. Chronicling innovations, revolutions, cyber attacks, and meltdowns across seven episodes, this limited series podcast untangles the web in a way you’ve never considered before. Featuring memes and moments you know — like when the world became transfixed by the color of a dress — and others you don’t, but should — like how people sent death threats to the woman who posted that meme online — LONG SHADOW: BREAKING THE INTERNET both scales the heights of internet virality and plumbs the depths of social media's depravity. Within weeks of its launch in 2021, LONG SHADOW became a No. 1 history show on Apple Podcasts, and its first season, 9/11’s LINGERING QUESTIONS, won Best History Podcast at the inaugural Signal Awards. Its second season, RISE OF THE AMERICAN FAR RIGHT, was named Best Podcast at the 2024 Edward R. Murrow Awards. IN GUNS WE TRUST, the show’s third season produced in collaboration with The Trace, was nominated for a Peabody Award and awarded the RFK Human Rights Journalism Award for its coverage of America’s gun violence epidemic. LONG SHADOW: BREAKING THE INTERNET premiered June 24, 2025 and won three Signal Awards (for Best Technology, Documentary, and History podcast) as well as an Anthem Award for Best Responsible Technology Awareness.
