For over 25 years, the Twin Towers defined the New York skyline and epitomized everything the United States stood for. And then in just a couple of hours, they were gone. 9/11 remains the deadliest act of terrorism on American soil, but how did an attack of this scale happen and why were we so unprepared for it? Through investigative reports, declassified documents, and interviews with first responders and those who were involved at the highest level, we reveal ten fatal mistakes that together led to that horrific, tragic day.

Two air catastrophes within five months of each other, both involving the same plane: the Boeing 737 MAX. How could these brand-new passenger jets, built by one of aviation's most trusted companies, just fall out of the sky? Now, through newly uncovered records, plus interviews with experts who investigated the crashes, we reveal why this seemingly reliable aircraft was headed toward disaster from the very beginning, and list the series of miscalculations, mistakes, and fraudulent maneuvers that sent 346 people to their deaths in 2018 and 2019.
