20th anniversary of 9/11: When to watch documentary series ‘Ten Steps to Disaster: Twin Towers’

Details of how flawed safety planning opened the world’s eyes to a new form of radical terrorism

For over 25 years, the Twin Towers defined the New York skyline and epitomized everything the United States of America stood for. But in a couple of hours, the iconic building was gone, and with them, almost three thousand people died victims of the deadliest act of terrorism on American soil, while thousands more were injured.

People often question how an attack of this scale happened and why the nation was so unprepared for it? To answer this interrogative and many more, the Smithsonian Channel has prepared the documentary series “Ten Steps to Disaster: Twin Towers” to shed light on the storm of mistakes, missteps, and missed opportunities that led to one of the world’s worst disasters, the World Trade Center terror attacks, also known as 9/11.
