Pull up is one of the most recognisable alerts from a modern airliner ground proximity warning system, which monitors an aircraft height above terrain and warns the crew to climb immediately. The McDonnell Douglas MD-11, a wide body trijet airliner developed in the late 1980s, carried such a system as part of its advanced cockpit. Recordings of its warning have circulated among aviation enthusiasts, flight simulator players and documentary makers, who reuse the sound because it instantly communicates danger without explanation. Its clipped synthetic delivery has made it a shorthand for an emergency in the air.

The sharp 'pull up' terrain warning from a McDonnell Douglas MD-11 cockpit, used in aviation videos and memes to signal danger or a last-second save.
This short clip captures the urgent pull up warning heard in a McDonnell Douglas MD-11 cockpit when the aircraft is dangerously close to terrain. A firm synthetic voice repeats the command over a sharp alert tone, cutting through engine noise with an unmistakable sense of emergency. The warning is designed to demand an immediate climb, and hearing it outside the cockpit instantly raises tension because listeners recognise it from aviation documentaries, flight simulator videos and crash investigations. Even at just a few seconds long, it creates a feeling of narrow escape, making it a powerful cue for moments when something is about to go badly wrong.
