ayday, also known as Air Crash Investigation in the United Kingdom, Ireland, Australia, South Africa and Asia, and Air Emergency and Air Disasters in the United States, is a Canadian documentary television programme produced by Cineflix investigating air crashes, near-crashes and other disasters. Mayday uses re-enactments, interviews and computer-generated imagery to reconstruct for its audiences the sequence of events leading up to each disaster. In addition, aviation experts, retired pilots and crash investigators are interviewed explaining how these emergencies came about, how they were investigated and how they could have been prevented.
Cineflix started production on 13 August 2002, with a CDN$2.5 million budget. Cineflix secured deals with France 5, the Discovery Channel, Canal D, TVNZ, the Seven Network, the Holland Media Group and the National Geographic Channel, to take Mayday to 144 countries and 26 languages. The series was received well by critics and nominated for a number of awards. Sharon Zupancic won a Gemini Award for her work on the Mayday episode, "Lockerbie Disaster". UNSW's senior lecturer, Raymond Lewis, conducted a study on teaching strategy loosely based on the series. Lewis's results indicated using the strategy had "a positive effect on learning outcomes."Overview from themoviedb.org
