The clip comes from the cockpit voice recording of Polish Air Force Tu-154M flight 101, which crashed while approaching Smolensk, Russia, on 10 April 2010. The repeated pull up call is the aircraft's terrain warning, triggered as the jet descended toward ground it should have cleared. Transcripts and excerpts from the recording later circulated online, where the short warning sequence was separated into a standalone soundboard clip. It remains in use mainly as a historical and educational reference, rather than as a meme, because listeners recognise the alarm instantly.
