Canadian documentary series featuring airline accidents and incidents. It has a strong following on niconico and thus, many memes were made about the dub and the various featured crews, whether they show superior Airmanship (as in the Gimli Glider incident) or complete ineptitude (as in Air France Flight 447).
Pixiv users often add this tag humorously to images that cause the viewer to panic.
