It reveals events that led up to each disaster, the causes of the incidents and the measures recommended in the report by the NTSB or the investigating Commission to prevent a similar incident happening again. It features re-enactments, interviews, eyewitness testimony, computer-generated imagery, and in some episodes cockpit voice recordings were used to reconstruct the sequence of events to the audiences.
