Mayday, also known as Air Crash Investigation(s) in the United Kingdom, Australia and Asia and Air Emergency and Air Disasters in the United States, is a Canadian documentary television program produced by Cineflix investigating air crashes, near-crashes, fires, hijackings, bombings and other disasters. 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.
As of Febuary 17, 2012, a total of 83 episodes of Mayday have aired including five "Science of Disaster" specials and three "Crash Scene Investigation" spin-offs.
