The 'pull up' callout is the classic Ground Proximity Warning System alert, the automated voice that warns pilots of dangerous terrain closure and commands an immediate climb. Heard in airliner cockpits since the 1970s, when terrain warning systems became standard equipment, it is one of the most recognisable sounds in aviation. The Boeing 707, the pioneering four-engine jet airliner of the late 1950s, gives this clip its vintage flavour. Online it circulates through flight simulator videos and aviation meme edits, where the urgent command turns any close call into instant comedy or tension.
À propos de ce son
The robotic 'pull up' terrain warning from a Boeing 707 cockpit, repeating urgently over engine noise. Creators use it for near-miss clips, fails and memes.
This is the unmistakable 'pull up' terrain warning from the cockpit of a Boeing 707. A flat, robotic synthetic voice repeats the command again and again, urgent and emotionless, layered over the low roar of jet engines. It is the sound of a jet seconds from disaster, the last automated plea before the pilots react. Hearing it makes any viewer tense instantly, because the voice never panics while the situation clearly is. That contrast between the calm machine voice and the implied danger is what gives the clip its punch.
