Air Holocaust (English: Mayday, Air Crash Investigation or Air Emergency) is a documentary program produced by Cineflix of Canada and broadcast on National Geographic Channel and Discovery Channel around the world. This program mainly introduces the major aviation accidents that occurred after the invention of the black box in the 1970s. Season 11 is currently on the air, and season 12 is also planned. In the third season, there are three episodes interspersed with railway accidents and navigation accidents (these three episodes may not be classified as a series of air havoc when broadcast overseas, and Taiwan's National Geographic Channel lists them as the "scene of Holocaust" series).
