This recording was made during takeoff aboard Aer Lingus EI-DVH, an Airbus A320-200 powered by CFM56 engines. The buzzsaw nickname comes from the distinctive sound those engines make at high thrust, caused by fan blade tips interacting with the intake airflow. Aviation fans have shared the effect for years in plane spotting communities, flight simulator videos, and social media edits. Its short, punchy character keeps it popular as a recognisable cue for jet power, departure, and the excitement of getting airborne.
