The phrase cleared for takeoff is standard aviation radio language used by controllers around the world to authorise a departing aircraft, which is why it sounds so familiar even to people who have never flown. Short recordings of air traffic control have long circulated online among aviation fans, and the clip has since become a handy shorthand in short videos for starting a journey, leaving somewhere behind or building anticipation. Its calm, professional delivery keeps it instantly recognisable and easy to drop into travel content.
