The F-35 Lightning II is a modern single-engine stealth fighter used by the United States and several allied air forces, known for its distinctive, extremely loud engine note at airshows and flypasts. Short recordings of its flybys have circulated widely on video platforms and soundboards, where editors reuse them as ready-made jet audio without needing original footage. The clip remains popular because the sound is instantly recognisable as a modern military jet, making it a quick shorthand for speed, power and high-tech warfare in edits, memes and gaming videos.
