Twenty-two years ago, two planes crashed into the Twin Towers. Another plane hit the Pentagon, and another crashed in Pennsylvania — killing nearly 3,000 people in total. The attacks became the pretense for a sprawling, ongoing war on terror that has directly and indirectly claimed some 4.5 million lives in post-9/11 war zones, including Afghanistan, Pakistan, Iraq, Syria, and Yemen, according to a 2023 estimate from Brown University.  In his 2021 podcast, 9/12, Dan Taberski brought us the story of a documentary filmmaker named Dylan Avery, whose 2005 film Loose Change helped embolden the 9/11 Truther Movement. In this piece, OTM reporter Micah Loewinger speaks with Taberski about Loose Change, and the complicated notoriety it brought to Avery. He also interviews Korey Rowe, a producer on Loose Change, about how Google Video helped it become the internet's first viral film. Then, Micah speaks with Charles B Strozier, author of Until the Fires Stopped Burning: 9/11 and New York City in the Words and Experiences of Survivors and Witnesses, about the moment when exactly 9/11 conspiracy theories broke into the mainstream.
