The stick shaker is a stall warning system fitted to Boeing aircraft, where a motor shakes the control yoke to alert pilots before lift is lost. The sound has become familiar beyond real cockpits through flight simulator videos, aviation training clips and online explainers, where creators replay the rattling to show how close an aircraft is to stalling. It remains widely used because the noise is instantly recognisable as a cockpit emergency cue, even for viewers who have never flown a plane.
