The phrase comes from aircraft ground-proximity warning systems, which alert pilots when terrain rises dangerously close beneath the plane, rather than from a film or television character. Because the DC-10 is a well-known wide-body airliner, clips labelled with that aircraft often circulate among aviation fans and flight simulator players. Online, the sound spread through crash compilations, simulator streams and short aviation memes, where its instantly recognisable alarm cuts through other audio. It remains popular because it signals danger in seconds, even to viewers who know nothing about flying.
